Answer:
438.55 ft²
Step-by-step explanation:
1 bag = 125.3 ft²
3.5 bags = 125.3 • 3.5 ft²
= 438.55 ft²
Answer:
y = 20 + 40x
Step-by-step explanation:
You can see that where x = 0, y = 20, which gives us the y intercept. We can also see that for each step on the grid, x increases by 0.5, and y increases by 20. Which means that y increases at a rate of 20/0.5 - or 40 - with respect to x.

Answer:
A confidence interval for a mean should be constructed to estimate the variable of interest.
Step-by-step explanation:
The confidence interval for a mean uses the sample mean to estimate the true population mean. Since it is a confidence interval, instead of a single number for the mean, the result shows a lower estimate and an upper estimate of the mean. In this experiment, the confidence interval cannot be for a proportion since the population of healthy males is unknown, but the calculation is being done with a sample of 75 healthy males.
Answer:
The length of arc of circle with interior angle 60° is 18 meter
Step-by-step explanation:
Given as :
The circumference of circle = C = 108 meters
The interior angle at center of circle = 60°
Let The length of arc = L
So ,
Length of arc = L = 
∵ circumference of circle =
Or, 108 =
∴ r =
So, Length of arc = 
Or, L = 
Or, L =
= 18 m
Hence The length of arc of circle with interior angle 60° is 18 meter Answer
