If a bicycle wheel has a diameter of 21 inches what the exact circumference?

Blababa [14]

Answer:

Circumference = 65.97344573

Step-by-step explanation:

Given the diameter of a circle, we can use the formula C = πd to find the circumference.

C = circumference

π = pi

d = diamater

Equation: 21(π) = 65.97344573

Make sure to round to whatever decimal place is asked for!

Sue took a test in both biology and math last week. The biology test had a mean of 70 and a standard deviation of 7 whereas the

Anna [14]

Answer:

c. the biology test

Step-by-step explanation:

To answer this problem we need to calculate the z-score of both tests, using the formula:

z = (x - μ) / σ

Where x is Sue's score, μ is the mean, and σ is the standard deviation.

For the biology test, the z-score is:

z = (76 - 70) / 7 = 6/7 = 0.857

For the math test, the z-score is:

z = (76 - 75) / 10 = 1/10 = 0.100

Because the z-score for the biology test is greater than the z-score for the math test, Sue did better in the biology test, in comparison to the rest of the class.

E=6c^2−2c−1 F=−4c^2+7c+5 E+F=

IRINA_888 [86]

The answer of given equation is $2c^{2}$ + 5c +4

Step-by-step explanation:

By putting the given values of E and F we get,

E + F

=( $6c^{2}-2c-1$ ) + (- $4c^{2}+7c+5$ )

Here we will take the coefficient of same variable together

=( $6c^{2}-4c^{2}$ ) +( -2c +7c) +( -1+5)

= $2c^{2}$ + 5c +4

Hope this helps you.
