Answer:
Domain: 5, 6, 7, 8
Range: 0, -2, 10, -3
The relation is a function because each x-value has its own y-value.
Step-by-step explanation:
Domain: Set of all first elements in relation
Range: Set of all second elements in relation
How to determine if the relations is a function:
1. Identify the input values.
2. Identify the output values.
3. If each input value leads to only one output value, classify the relationship as a function.
the rate of change of function g from x=-3 to x=-1 is the same as it is from x=-1 to x=1. Is function g linear, quadratic or exponential?
Answer:
We conclude that we conclude that the rate of change of a linear function g from x=-3 to x=-1 is the same as it is from x=-1 to x=1.
Thus, the function is linear.
Step-by-step explanation:
We know that the rate of change remains constant for a linear function.
In other words, the rate of change does not change for the entire domain of a linear function.Comparing with the slope-intercept form
The slope-intercept form of a linear function is
[tex]y = mx+b[/tex]
where m is the slope or rate of change
For example, considering the linear function
[tex]y = 6x + 4[/tex]
Then the average rate of change is 6 over any interval selected.
Therefore, we conclude that we conclude that the rate of change of a linear function g from x=-3 to x=-1 is the same as it is from x=-1 to x=1.
Thus, the function is linear.
30 is 5/6 of what number?
Answer:
12
Step-by-step explanation: because 30 divided by 5/6 gives you your simplified answer of 12 when you switch over the incomplete progress of elimination when overwriting your decimal place so , that gives you 12
The solution for a number that satisfies the condition ''5/6 times a number is 30.'' is, 12
We have to give that,
To find a number which is 5/6 times a number is 30.
Now, let us assume that,
A number = x
Hence, it can be written as,
⇒ [tex]\dfrac{5}{6} \times x = 30[/tex]
Solve for x,
Multiply by 6 on both sides,
⇒ [tex]5x = 10 \times 6[/tex]
⇒ [tex]5x = 60[/tex]
Divide 5 on both sides,
⇒ [tex]x = \dfrac{60}{5}[/tex]
Simplify it,
⇒ [tex]x = 12[/tex]
Therefore, the solution is, x = 12

To increase attendance for a flower show, flower shops in the area offered discount coupons to their customers. Show attendance was higher this year, which the organizers attributed to the many discount coupons attendees used. However, the organizers are warned that weather could be a confounding variable in interpreting the rise in attendance.
Which statement could explain the effect of confounding?
Because the weather was worse last year, fewer coupons were distributed compared to this year.
Because the weather was similar in both years, it most likely played no role in the attendance increase.
Because coupons were handed out this year and not last year, the weather was different this year compared to last year.
Because the weather was generally better this year compared to last year, the attendance may have increased.
Answer:
The statement which could explain the effect of confounding is:
Because the weather was generally better this year compared to last year, the attendance may have increased.
Step-by-step explanation:
A confounding variable has some effect on the dependent variable. Confounding variables are the variable(s) that are additional to the independent and dependent variables in an experiment. Since the presence of confounding variables affect the variables being studied so that the results do not reflect the actual relationship, it is best to exclude or control them through randomization, restriction, and matching.

Use the normal distribution to approximate the following binomial distribution. A recent survey indicated that 55% of the people in a certain community own a motorcycle. If 35 people from this community are chosen at random, what is the probability that fewer than 23 own a motorcycle?
Answer:
0.86 (Approx)
Step-by-step explanation:
Given:
n = 35
P = 55% = 0.55
Q = 1 - p = 0.45
Computation:
Standard deviation σ = √npq
Standard deviation σ = √(35)(.55)(.45)
Standard deviation σ = 2.9432
Mean μ = np = 35 x 0.55 = 19.25
p[(x-np)/ σ ]
P[z<1.04204]
= 0.86 (Approx)
Which three lengths could be the lengths of the sides of a triangle?
A. 6 cm, 23 cm, 11 cm
B. 10cm, 15cm, 24cm
C. 22 cm, 6 cm, 6 cm
D. 15 cm, 9 cm, 24 cm
Answer:
D. 15 cm, 9 cm, 24 cm
Step-by-step explanation:
The three lengths that could be the lengths of the sides of a triangle, must satisfy the following condition;
---sum of any two smaller sides chosen must be equal to the third side.
Test option A : 6 cm + 11 cm = 17 cm ( 17 cm ≠ 23 cm)
Test option B: 10 cm + 15 cm = 25 cm (25 cm ≠ 24 cm)
Test option C: 6 cm + 6 cm = 12 cm (12 cm ≠ 22 cm)
Test option D: 15 cm + 9 cm = 24 cm (24 cm = 24 cm) ---correct option.
Thus, the three lengths that could be the lengths of the sides of a triangle are 15 cm, 9 cm, and 24 cm
Profit is the amount of money that remains after all expenses of a project have been paid. The year has just ended, and Ajax Construction's owner is anxious to find out if the company had a profitable year. The company was awarded five contracts totaling $7,435,000. The costs associated with each project were: Project 1: $1,245,000 Project 2: $985,689 Project 3: $1,723,000 Project 4: $2,567,054 Project 5: $633,768 How much profit did the company earn?
Answer:
the Profit earned by the company is $280,489
Step-by-step explanation:
Total Cost of 5 projects awarded = $7,435,000
Cost of Project 1 = $1,245,000
Cost of Project 2 = $985,689
Cost of Project 3 = $1,723,000
Cost of Project 4 = $2,567,054
Cost of Project 5 = $633,768
We need to find the profit earned by the company.
First we need to find Total cost spent on all 5 projects.
It can be found by adding cost spent on all projects.
Total cost spent on all 5 projects = Cost of Project 1 + Cost of Project 2 + Cost of Project 3 + Cost of Project 4 + Cost of Project 5
Total cost spent on all 5 projects = $1,245,000+ $985,689 + $1,723,000+ $2,567,054 + $633,768
Total cost spent on all 5 projects = $7,154,511
Now we can calculate profit earned using formula:
Profit earned = Total Cost of 5 projects awarded - Total cost spent on all 5 projects
Profit earned = $7,435,000 - $7,154,511
Profit earned = $1,280,489
So, the Profit earned by the company is $280,489

takes. How long will her sister take to knit 8 similar scarves?
The time taken by sister of Eva to knit 8 similar scarves, if Eva can knit 2/5 of a scarf in an hour. Her sister takes 3/4 of the time she takes is 2.4 hours.
What is the ratio?It is the contrast of two different quantities. For instance, if your father weighs 90 kg, and you weigh 30 kg, the weight ratio is 1:3.
Given:
Eva can knit 2/5 of a scarf in an hour. Her sister takes 3/4 of the time she takes,
Calculate the time taken by the sister of Eva as shown below,
The time taken by the sister to knit a scarf = 3 / 4 × 2 / 5 hours
The time taken by the sister to knit 8 scarves = 3 / 10 × 8 hours

6. Given a line with slope m=-2 that passes through the point (-3, 4), find the equation of
in standard form.
A. 2x + y - 2 = 0
B.2x -y-2 = 0
C. 2x + y + 2 = 0
D.y = 2x + 2
Answer:
first write the equation in point-slope form
y - 4 = -2 (x - (-3)) (then, solve the equation to get your answer)
y -4 = -2 (x +3) (use the distributive property)
y - 4 = -2x -6 (add 6 to both sides)
y +2 =-2x (add 2x to both sides)
2x +y +2= 0 (this is your answer)

The square below represents one whole. Express the shaded area as a fraction, a decimal, and a percent of the whole. Fraction: Decimal: Percent: %
Answer:
Fraction = [tex]\frac{19}{50}[/tex]
Decimal = 0.38
Percent = 38%
Step-by-step explanation:
Number of shaded rectangles = 38
Total number of rectangles = 100
Fraction represented by the shaded area = [tex]\frac{\text{Number of blocks shaded}}{\text{Total number of blocks}}[/tex]
= [tex]\frac{38}{100}[/tex]
= [tex]\frac{19\times 2}{50\times 2}[/tex]
= [tex]\frac{19}{50}[/tex]
Decimal form of the shaded area = [tex]\frac{38}{100}[/tex] = 0.38

(6e-3f-3/4) in a equivalent expression
Answer:
Step-by-step explanation:
(6e-3f-3/4) contains two terms which do not involve fractions and one fractional term (3/4).
We can safely remove the parentheses. Then:
(6e-3f-3/4) => 6e - 3f - 3/4
That is "an equivalent expression."
We could go further and create one equivalent fraction. Multiply the first two terms by 4/4, obtaining:
24e 12f 3 24e - 12f - 3 3(8e - 4f - 1
------ - ------ - ----- => ---------------------- => -------------------
