The constant of proportionality is the slope of the line.
The slope is the change in y over the change in x
Using two pints on the line:
Slope = (3-0) / (1-0) = 3/1 = 3
The answer is 3
Answer:
Pual needs 3 gallons
Step-by-step explanation:
∵ The dimensions of the four walls are:
25 × 8 , 30 × 8 , 25 × 8 , 30 × 8
∴ The area of painting = 2(25 × 8) + 2(30 × 8)
= 400 + 480 = 880 square feet
∵ each gallon paint 400 square feet
∴ The number of gallons = 880/400 = 2.2, so he needs 3 gallons
The area of a rectangle is calculated my multiplying the length of the rectangle and the width of the rectangle. In this case, the length (the longer side) is 70 feet while the width (shorter side) is 30 feet. Hence the area is 2,100 ft2.
Answer:
Step-by-step explanation:
1/3 x 1/3 in exponential notation is 1/3². you are multiplying a number by itself so its squared, ig you are multiplying a number by itself three times, then its cubed, with a 3.
Sample mean : \overline{x}=10.6x=10.6
Standard deviation : s=1.7s=1.7
Significance level : \alpha:1-0.95=0.05α:1−0.95=0.05
Critical value : z_{\alpha/2}=1.96
Hence the 95% confidence interval for the number of chocolate chips per cookie for big chip cookies= (10.1989,\ 11.0011)(10.1989, 11.0011)
