The likelihood that they will choose to work in an animal shelter for each of the six options they choose is around 0.2214 or 22.14%

The probability is given as,

P = (Favorable event) / (Total event)

The likelihood of choosing an opportunity at an animal shelter is 7/9. If each chance is equally likely to be chosen, the likelihood of choosing six in a row from an animal shelter may be estimated by multiplying the likelihood of choosing one opportunity by itself six times:

P = (7/9) x (7/9) x (7/9) x (7/9)

P = (7/9)⁶

P = 0.2214 or 22.14%

Answer:

x is 25

Step-by-step explanation:

There is a common ratio between the sides. In this case, 35/28 is 1.25. This is the number you have to multiply to 20. 1.25 * 20 = 25.

The equation that could be used to determine the amount of money the Hensing apartment complex bills in rent each month when all of their units are rented out is A. y = $(600x^2 - 180).

The Hensing apartment complex rents out each unit for $20 less monthly than the Winberg complex, so the rent for each unit is $200x - $20 = $180x.

The equation that represents this situation is: y = $(600x^2 - 180

So the answer is (A) y = $(600x^2 - 180).

The class that contains the 80 th percentile is d) 32-34.

First, find the total frequency of the income :

Total frequency = 2 + 11 + 8 + 5 + 4 = 30

The required vertical distance from the top of the slide to the bottom of the pool is 43.8 feet.

We can use trigonometry to solve this problem. Let's call the vertical distance from the top of the slide to the bottom of the pool "h" (in feet). We can use the angle of depression (45°) to find the horizontal distance from the top of the slide to the bottom of the pool. Since the slide has a constant slope, the angle between the slide and the ground is also 45°. It implies that the vertical height is equal to the horizontal projection of the slide.

Apply Pythagorean theorem,
45² = h² + h²
h = 45/√2
h = 31.8

Now, as mentioned that depth of the pool is 12 feet so, the total vertical height is given as,
= h + 12
= 31.8 + 12
= 43.8 feet

Thus, the required vertical distance from the top of the slide to the bottom of the pool is 43.8 feet.

3. The radii of the gravel bases must be greater than or equal to the radii of the food containers, which is equal to x:

4. The radii of the gravel bases must also be less than or equal to half the width of the pen, which is equal to y/2:

System of inequalities that can be used to determine the width of the pen, y, and the radii of the gravel bases, x, is:

Answer:

Step-by-step explanation:

The sum of the diameters of the gravel bases cannot exceed the width of the pen, so 2⁢x+2⁢x≤y. Rewrite this to get y≥4⁢x as the first inequality in the system.Next, to write the expression for the cost of the fencing, find the perimeter of the rectangle and multiply the perimeter by the cost per foot of fencing. The pen is a rectangle, so the perimeter is 2⁢(10)+2⁢(y), or 20+2⁢y. Multiply the cost ($4.00 per foot) by the perimeter to get 4⁢(20+2⁢y).Now write an expression for the gravel bases for the circular food containers. Because A=π⁢r2 and the cost of the gravel is $2.00 per square foot, multiply the cost of the material by the sum of these areas to get 2⁢(π⁢x2)+2⁢(π⁢x2).The total cost must be less than or equal to $150, so we can say that 4⁢(20+2⁢y)+2⁢(π⁢x2)+2⁢(π⁢x2)≤150. Finally, simplify and solve for y.80+8⁢y+2⁢π⁢x2+2⁢π⁢x2≤15080+8⁢y+4⁢π⁢x2≤1508⁢y≤70−4⁢π⁢x2y≤8.75−0.5⁢π⁢x2So, this is the system.

y≥4⁢x

y≤8.75−0.5⁢π⁢x2

Answer:

The area of one planter is:

4 1/5 in × 1 1/3 in = (21/5) in × (4/3) in = 28/5 in²

In a 3 x 3 array, there are 3 planters in each row and 3 planters in each column, so there are a total of 9 planters.

The area covered by the planters is:

9 × (28/5) in² = 252/5 in² ≈ 50.4 in²

Therefore, the area covered by the planters is approximately 50.4 square inches.

The z-score for 71 is -1.

z-score is a measure of how many standard deviations an observation or data point is away from the mean of a distribution.

It is calculated by subtracting the mean from the observation and then dividing the result by the standard deviation: z = (x - μ) / σ

A positive z-score means that the data point is above the mean, while a negative z-score means that it is below the mean.

Applying the formula to solve our question

Here is a proven formula to use:

z = (x - μ) / σ

where:

x = the data item (x = 71)

μ = the mean of the distribution (μ = 80)

σ = the standard deviation of the distribution (σ = 9)

Substituting the values, we get:

z = (71 - 80) / 9

z = -1

Answer:

Step-by-step explanation:

To find the mean of a set of data, we add up all the values in the set and then divide by the number of values.

Adding up the values in the set, we get:

3 + 5 + 4 + 4 + 5 + 7 + 7 = 35

There are 7 values in the set, so we divide the sum by 7 to get the mean:

mean = sum of values / number of values

mean = 35 / 7

mean = 5

An inequality can be represented graphically as a region on one side of a line. Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.

The first inequality with a solid line has a y-intercept of -1 and since it is shaded above the line, we will use ≥.

Two coordinates on the line are: (0, -1) and (1, 2)

The slope = (2 + 1)/(1 - 0) = 3

Thus, inequality is:

y ≥ 3x - 1

The second inequality with a dashed line has a y-intercept of 4 and since it is shaded below the line, we will use <.

Two coordinates on the line are: (4, 0) and (0, 2)

The slope = (2 - 0)/(0 - 4) = -1/2

Thus, inequality is:

y < -¹/₂x + 4

The coordinates of vertex B' are (76, -86).

In Mathematics and Geometry, a dilation is a type of transformation which typically changes the size of a geometric object, but not its shape.

Next, we would have to dilate the coordinates of the preimage by using a scale factor of 9 centered at the point D (-5, 5) by using this mathematical expression:

(x, y)  →  (k(x - a) + a, k(y - b) + b)

For coordinate B, we have;

Coordinate B = (4, -4)  →  (9(4 - (-5)) + (-5), 9(-4 - 5) + (-5))

Coordinate B = (4, -4)  →  (9(9) - 5, 9(-9) - 5)

The measure of the angle CAB in a right angled triangle ABC using given measurements is equal to  37°.

In the triangle ABC,

From the figure we have,

Measure of angle ABC = 90 degrees

Measure of angle ACB= 53 degrees

Sum of all the interior angles of a triangle is equal to 180 degrees .

⇒Measure of angle ABC + Measure of angle ACB + Measure of angle CAB = 180 degrees

⇒ 90° + 53° + Measure of angle CAB = 180°

⇒143° + Measure of angle CAB = 180°
