Corresponding Angles are congruent. Which angle corresponds with 3? 1/2 3/4 fine 7/8 5 6 [?]​

Answer:

(- 2, - 8 )

Step-by-step explanation:

y = 4x → (1)

y = 8x + 8 → (2)

substitute y = 8x + 8 into (1)

8x + 8 = 4x ( subtract 4x from both sides )

4x + 8 = 0 ( subtract 8 from both sides )

4x = - 8 ( divide both sides by 4 )

x = - 2

substitute x = - 2 into (1)

y = 4x = 4(- 2) = - 8

solution is (- 2, - 8 )

To make "x" the subject of the equation, we can isolate it on one side of the equation by multiplying both sides by 15:

x/15 = h

Multiplying both sides by 15 gives:

x = 15h

The equation in terms of "x" is x = 15h.

Step-by-step explanation:

Answer:

From the given figure, we can write the following equations:

n(A) = 2x + 4

n(B) = x + 5

n(A∪B) = n(A) + n(B) - n(A∩B)

Since we are given that n(A) = n(B), we can substitute the expressions for n(A) and n(B) to get:

2x + 4 = x + 5

x = 1

(a) x = 1

(b) n(A) = 2x + 4 = 2(1) + 4 = 6

(c) n(B) = x + 5 = 1 + 5 = 6

(d) n(A∪B) = n(A) + n(B) - n(A∩B)

We still need to find n(A∩B) to calculate n(A∪B). Looking at the figure, we can see that there are 2 elements that are common to both A and B. Therefore,

n(A∩B) = 2

Substituting this value, we get:

n(A∪B) = n(A) + n(B) - n(A∩B) = 6 + 6 - 2 = 10

Therefore, (d) n(A∪B) = 10.

Step-by-step explanation:

The line of reflection is y = -1, which is the equation of the horizontal line passing through the midpoint of the line segment joining E and E'.

Two different points on a line define the boundaries of a line segment in geometry. Or, a line segment is a section of the line that links two points, as another alternative. In contrast to a line, which has no endpoints and can go on forever, a line segment has two distinct endpoints that are set or identifiable.

From the given image, we can see that the original polygon ABCDE has point E at (-3, 1), and the reflected polygon A'B'C'D'E' has point E' at (-3, -3). This means that the reflection must have occurred across the horizontal line passing through the point (-3, -1), which is the midpoint of the line segment joining E and E'.

Therefore, the line of reflection is y = -1, which is the equation of the horizontal line passing through the midpoint of the line segment joining E and E'.

The intervals during which the ball's height is increasing are: [0, 2.5] and

[5, 7.5]

In a graph, an interval represents a range of values along the x-axis or y-axis. It is a continuous segment of the axis between two points, often used to indicate a particular range of values or a specific time period.

Since the graph represents the height of the ball h in feet after t seconds, we can find the interval during which the ball's height is increasing by examining the slope of the graph.

If the slope of the graph is positive, the height of the ball is increasing. If the slope is negative, the height of the ball is decreasing.

Looking at the graph, we can see that the slope of the graph is positive between approximately 0 and 2.5 seconds, and between approximately 5 and 7.5 seconds.

1.Jake became anemic after the first blood transfusion because his body reacted to the foreign antigens.

2.He went into an anaphylactic shock after the second transfusion due to an even stronger allergic reaction.

1. After the first blood transfusion, Jake became anemic because he was given type O blood, which is not compatible with his own blood type. Incompatible blood transfusions occur when a person is given blood that carries a different antigen than the one they have. In this case, Jake was given type O blood, which carries both the A and B antigens, while Jake’s own blood carries the Rh antigen. Therefore, Jake’s body reacted to the foreign antigens and created antibodies to fight against them. This reaction caused Jake to become equation anemic, as his body was not able to absorb the oxygen from the transfused blood.

2. After the second blood transfusion, Jake went into an anaphylactic shock because he was given type O blood, which carries both the A and B antigens, while Jake’s own blood carries the Rh antigen. Since Jake’s body had already created antibodies to fight against the foreign antigens, when it was exposed to the same foreign antigens a second time, his body reacted with an even stronger immune response. This reaction caused Jake to go into an anaphylactic shock. In other words, the second transfusion caused an allergic reaction in Jake’s body, which was much more severe than the allergic reaction caused by the first transfusion.

If the 8th term of an A.P is twice the 4th term and the sum of the first terms is 47. the five common difference is 3.

Let the first term be "a" and the common difference be "d".

The 4th term of the AP is: a + 3d

The 8th term of the AP is: a + 7d

We know that the 8th term is twice the 4th term, so:

a + 7d = 2(a + 3d)

Simplifying and solving for "a", we get:

a = d

Substituting this value of "a" in the sum of the first terms, we get:

47 = (5/2)(2a + 4d)

47 = 5(a + 2d)

9.4 = a + 2d

Answer:

Step-by-step explanation:

The equation you provided, y = 2/5 + 2, appears to be missing the variable x. Assuming you meant y = 2/5x + 2, here's how you can find the x-intercept:

To find the x-intercept, we need to find the value of x when y = 0. This is because the x-intercept is the point on the graph where the line crosses the x-axis, and at that point, the y-coordinate is always 0.

So, we can set y = 0 in the equation:

0 = 2/5x + 2

Subtracting 2 from both sides:

-2 = 2/5x

Multiplying both sides by 5/2:

-5/2 = x

Therefore, the x-intercept is at the point (-5/2, 0).

For the first finding on job-search satisfaction scale, the estimated Cohen’s d is not provided in the question. However, assuming that it is provided in the actual data, the psychologist can use Cohen’s guidelines for interpreting the effect size based on the estimated Cohen’s d. According to Cohen’s guidelines, an effect size of 0.2 is considered small, 0.5 is considered medium, and 0.8 or higher is considered large. Therefore, the psychologist needs to compare the estimated Cohen’s d with these values to evaluate the effect size.

For the second finding on the number of months worked in the last year, the estimated Cohen’s d is also not provided in the question. The psychologist can use the same approach to evaluate the effect size using Cohen’s guidelines based on the estimated Cohen’s d.

Alternatively, the psychologist can also use r² as a measure of effect size. R² represents the proportion of variance in the outcome variable that is explained by the treatment or intervention. According to Cohen’s guidelines for r², an effect size of 0.01 is considered small, 0.09 is considered medium, and 0.25 or higher is considered large. Therefore, the psychologist can compare the estimated r² with these values to evaluate the effect size.

Based on the information provided, both findings show statistically significant results with treatment effects. However, the actual effect sizes cannot be evaluated without the estimated Cohen’s d or r² values.

Effect size for job-search satisfaction is Cohen's d = 0.7, t statistic = 4.12 and r² = 0.49.

According to Cohen's guidelines, a Cohen's d of 0.7 is considered a large effect size. This means that the workshop had a significant impact on the job-search satisfaction of the participants. The t statistic of 4.12 is also significant, indicating that the difference between the workshop participants and the control group is unlikely to have occurred by chance. The r² of 0.49 indicates that the workshop accounted for 49% of the variance in job-search satisfaction.

Effect size for months worked

Cohen's d = 0.36

t statistic = 2.38

r² = 0.13

According to Cohen's guidelines, a Cohen's d of 0.36 is considered a medium effect size. This means that the workshop had a significant impact on the number of months worked by the participants. The t statistic of 2.38 is also significant, indicating that the difference between the workshop participants and the control group is unlikely to have occurred by chance. The r² of 0.13 indicates that the workshop accounted for 13% of the variance in months worked.

Interpretation

Both of the effect sizes found by the psychologist are significant, indicating that the workshops had a positive impact on the job-search satisfaction and the number of months worked by the participants. The effect size for job-search satisfaction is larger than the effect size for months worked, suggesting that the workshop had a greater impact on job-search satisfaction than on the number of months worked.

Conclusion

The psychologist's findings suggest that the workshops had a positive impact on the job-search satisfaction and the number of months worked by the participants. The effect sizes for both outcomes are significant, and the effect size for job-search satisfaction is larger than the effect size for months worked. These findings suggest that the workshops may be an effective way to help unemployed people find jobs.

Area of shaded region= 1142.96mm²

Step-by-step explanation:

•First calculate the Area covered by the interior circle.

•To calculate the Area of the exterior circle first add the two radii to get the radius from the centre of the interior circle to the circumference of the exterior circle.

•Use the calculated radius to calculate the Area covered from the centre to the circumference of the exterior circle.

•Now subtract the Area of the interior circle from the area covered by the bigger circle to get the Area of the shaded region.

Answer:

1141.76

Step-by-step explanation:

To solve for the area of the entire circle, we must first solve for the radius. Adding 6 and 14 will get us the total radius of the circle.

Therefore, the radius of the entire circle is 20.

The expression you can use to solve for the area of a circle is:

Inserting the radius into the expression:

Therefore, the area of the entire circle is 400π.

If there is a hole in the circle in the shape of a circle, we must subtract the area of that hole to find the area of the shaded region.

Inserting 6 into the expression to solve for area:

Therefore, the area of the hole is 36π.

Now, we need to subtract the area of the gap from the area of the entire circle.

Because π is approximately equal to 3.14, we can calculate an approximate value for 364π by multiplying 364 by 3.14. This gives us:

Therefore, the area of the shaded region is [tex]1141.76^{2}[/tex]

Answer:

We can use the concept of proportions to solve this problem. We know that the ratio of the height of the tree to the length of its shadow is the same as the ratio of the height of the mailbox to the length of its shadow.

Let's call the height of the mailbox "x". Then, we can set up the proportion:

height of tree / length of tree's shadow = height of mailbox / length of mailbox's shadow

Plugging in the values we know, we get:

36 / 18 = x / 4

Simplifying the left side of the equation, we get:

2 = x / 4

To solve for x, we can multiply both sides of the equation by 4:

8 = x

Therefore, the mailbox is 8 feet tall.

→ A mail box casts 4 foot shadow.

Now we have to,

→ Find the height of the mail box.

Let us assume that,

→ Height of mail box = h

Forming the equation,

→ 36/18 = h/4

Then the value of h will be,

→ 36/18 = h/4

→ h/4 = 36/18

→ h/4 = 2

→ h = 2 × 4

→ [ h = 8 ft ]

Hence, the value of h is 8.

The ratio 3 mm : 3000 mm is 1:1000.

The ratio of 7500g:2 Kg is 3.75:1.

The ratio of 250ml:2l is 1:8.

To simplify this ratio, we need to find the greatest common factor (GCF) of 75 and 125, and divide both terms by it.

The factors of 75 are: 1, 3, 5, 15, 25, 75.

The factors of 125 are: 1, 5, 25, 125.

The GCF is 25.

Dividing both terms by 25, we get:

75 ÷ 25 = 3

125 ÷ 25 = 5

Therefore, the simplified ratio is 3:5.

1.1.2. 3mm:3m

To simplify this ratio, we need to convert the units so that they are the same.

1 m = 1000 mm

So, 3 m = 3000 mm

Now, the ratio is 3 mm : 3000 mm.

We can simplify this ratio by dividing both terms by 3:

3 mm ÷ 3 = 1 mm

3000 mm ÷ 3 = 1000 mm

Therefore, the simplified ratio is 1:1000.

1.1.3. 7500g:2 Kg

To simplify this ratio, we need to convert either grams to kilograms or kilograms to grams so that both terms have the same unit.

7500 g = 7.5 kg (since 1 kg = 1000 g)

Now, the ratio is 7.5 kg : 2 kg.

We can simplify this ratio by dividing both terms by 2:

7.5 kg ÷ 2 = 3.75 kg

2 kg ÷ 2 = 1 kg

Therefore, the simplified ratio is 3.75:1.

1.1.4. 250ml:21

To simplify this ratio, we need to convert milliliters to a whole number.

We can convert 250 ml to 250/21 ml by dividing both terms by 21:

250 ml ÷ 21 = 11.9 ml (rounded to one decimal place)

Now, the ratio is 11.9 ml : 21.

We can simplify this ratio by dividing both terms by 0.1:

11.9 ml ÷ 0.1 = 119 ml

21 ÷ 0.1 = 210

Therefore, the simplified ratio is 119:210.

1.1.5. 250 kg:2 tonnes

To simplify this ratio, we need to convert either kilograms to tonnes or tonnes to kilograms so that both terms have the same unit.

1 tonne = 1000 kg

So, 2 tonnes = 2000 kg

Now, the ratio is 250 kg : 2000 kg.

We can simplify this ratio by dividing both terms by 250:

250 kg ÷ 250 = 1 kg

2000 kg ÷ 250 = 8 kg

Answer: According to the histogram, a sum of 28 is not unusually low. The bar representing a sum of 28 has a height of 9, which is relatively high compared to some of the other bars. Additionally, the histogram is roughly symmetric, so a sum of 28 is not far from the mean of the distribution.

To find the probability that a person would roll a sum less than 28, we can standardize the value using the formula z = (x - mu) / sigma, where x is the sum of 28, mu is the mean of 35, and sigma is the standard deviation of 5.72.

z = (28 - 35) / 5.72 = -1.22

Using a standard normal distribution table or calculator, we can find that the probability of getting a z-score less than -1.22 is approximately 0.1112, or 11.12%. Therefore, there is about an 11.12% chance that a person would roll a sum less than 28.

Step-by-step explanation:

1. The number of sides of the polygon is 8

2. The value of x is 36

A polygon can be defined as a flat or plane. The sum of a regular polygon is expressed as (n-2)180. The sum of exterior angle of a polygon is 360.

Therefore the sum of the interior is 5 times the exterior.

(n-2)180 = 5×360

180n - 360 = 1800

180n = 1800-360

180n = 1440

divide both sides by 180

n = 1440/180

n = 8

therefore the number of sides of the polygon is 8

2. The number of sides of the polygon is 6

Therefore the sum of angle in the polygon = 6-2)180 = 4× 180

= 720°

x+3x+6x+4x+4x+2x = 720

20x = 720

x = 720/20

x = 36

therefore the value of x is 36
