Answer:
Step-by-step explanation:
The manager of fast food restaurant collected data to study the relationship between the number of employees working registers and the amount of time customers waited in line to order. He made a scatter plot of the data and credited a trend line with the equation y= -70x+300, where y is the total amount of time waited in seconds and x is the number of employees working registers.
1. Did the scatter plot of data positive, negative, or no association? Explain your reasoning.
2. Maria went to the restaurant and waited 90 seconds to place her order. Use the trend line equation to predict how many employees were working.
3. Kiara went to the restaurant and waited 3.5 minutes. Use the trend line to predict how many employees are working.
4. Ashton walked into the restaurant and 4 employees are working registers. Use the trend line equation to predict how long he will wait to place his order.
Answer:
Step-by-step explanation: "no association because depending on how many people are working and how many people are coming in at the same tome"

Tell whether ratios form a propotion
1/4; 3/12
54/10; 81/15
18/24; 15/20
someone help me pls:(
Answer: Ratios form a proportion if they are equal when cross-multiplied.
1/4 and 3/12
Cross-multiply these ratios to compare them: 1/4 * 12 = 3, 3/12 * 4 = 3.
So they are equal and form a proportion.
54/10; 81/15
Cross-multiply these ratios to compare them: 54/10 * 15 = 81, 81/15 * 10 = 54.
So they are equal and form a proportion.
18/24; 15/20
Cross-multiply these ratios to compare them: 18/24 * 20 = 15, 15/20 * 24 = 18.
So they are equal and form a proportion.
Hence, all the ratios mentioned above form a proportion.

Every New Year's Day, Jennifer brings 13 candies for each of her grandchildren and 20 more candies for the adults to share.
Let g represent the number of Jennifer's grandchildren and c represent the total number of candies she brings.
Find the value of c when g=9.
Answer:
We can use the given information to set up a system of two equations:
c = 13g + 20
c - 13g = 20
The second equation is obtained from the first equation by subtracting 13g from both sides.
To solve this system, we can use substitution.
First, we solve the second equation for c.
c = 20 + 13g
Then, we substitute this expression for c into the first equation.
20 + 13g = 13g + 20
Then, we simplify.
20 = 20
So, the value of c when g = 9 is 20 + 13 * 9 = 20 + 117 = 137.

4x+2+2x+10 = 90
6x + 12 = 90
x = 90-12/6
= x = 13
MARK ME AS BRAINLIEST
Answer:
x= 13
Step-by-step explanation:
4x+2+2x+10=90
collect like terms
4x+2x+10+2=90
6x+12=90
collect like terms again
move 12 to the other side then the sign will change to minus -
6x=90-12
6x=78
divide both sides by 6
6x/6=78/6
x=13

Sid has a baseball cap collection. 65% of his caps have sports team symbols. If 26 of the caps have the team symbols, how many total caps does Sid have?
39
40
73
91
B. 40
As we know Sid has 26 Caps
we also know that 26 is 65% of total
so let total caps = x
to calculate x
we know that percent = (Values*100)/total Values.......... i
and here Value = 26 caps
percentage = 65
So we have
65 = (26*100)/x---------------- (As we know that per = fraction*100)..... from i
65x= 2600x = 2600/65x=40 capsHence Answer is 40

A sports medicine major wanted to conduct an experiment to determine if there is a correlation between the members of the soccer team's leg strength and the time it takes for them to sprint 40 yards. He sets up the following test and records the data:
The time for 22 leg-press reps is 11.9 seconds.
Step-by-step explanation:The lines of best fit is the trend line of the dataset.
The equation of line of best fit is y = 0.120x + 9.274The time for 22 leg-press reps is 11.9 seconds(A) The equation of the line of best fitThe table is given as —
(x) : 12 32 7 26 28 15 1
(y) : 8.6 14.6 7.1 8.3 11.9 19.4 9.5
To determine the equation of line of best fit, we make use of a regression calculator.
Enter the above dataset in a regression calculator, the equation is: y = 0.120x + 9.274 (Approximated to Three Decimal Places / Rounded of to the Thousandths Place)
(B) The number of seconds for 22 leg-press repsThis means that x = 22.
So, we have:
y = 0.120 * 22 + 9.274
= 2.640 + 9.274
= 11.914
(Approximate to the nearest hundredths)
= 11.9
Hence, the time for 22 leg-press reps is 11.9 seconds.
