Let the temperature at 10am be x, then
x + 8 = 56
x = 56 - 8 = 48 degrees F

Let y be the temperature at 8am, then
y - 2 = 48
y = 48 + 2 = 50 degrees.

\bar{x}=61.98

Step-by-step explanation:

The sample mean \bar{x} is a point estimate of the population mean μ.

Given the heights of the 6 tomato plants sample below:

55.6, 59.4, 59.9, 62.9, 64.9, 69.2

Point Estimate,

\bar{x}=\dfrac{55.6+59.4+59.9+62.9+64.9+69.2}{6} \\=\dfrac{371.9}{6} \\\bar{x}=61.98

A single tennis court is 75% the width of a doubles tennis court. The singles court is 27 feet wide. How wide is the doubles cou
grandymaker [24]
X = 75% * y

Where 'x' is the single tennis court width, and 'y' is the doubles tennis court width.

Plug in what we know:

27 = 75% * y

75% = 0.75

27 = 0.75 * y

27 = 0.75y

Divide 0.75 to both sides:

y = 36

So the doubles court is 36 feet wide.
