Which expression are equivalent to 2(4f+2g)

Mathematics
1 answer:
Cloud [144]3 years ago
8 0

Answer:

8f+4g

Step-by-step explanation:

You have to distribute 2 to each number in the parentheses 2 times 4 is 8 and since 4 has a variable it is 8f and 2 times 2 is 4 and since 2 has a variable it is 4g. We don't combine the two because they have different variables. So the answer is 8f+4g. Hope this helped :)

Find the length of the missing side. PLEASE HURRY
Margarita [4]

Answer:

C. 40in

Step-by-step explanation:

a^{2}+b^{2} =c^{2} \\

so...

24^{2} +32^{2} =c^{2}

24^{2} = 576\\32^{2} =1024

576+1024=1600

\sqrt{1600} = 40

the missing side = 40in

An aptitude test is designed to measure leadership abilities of the test subjects. Suppose that the scores on the test are norma
Komok [63]

Using the normal distribution, it is found that 0.0329 = 3.29% of the population are considered to be potential leaders.

In a <em>normal distribution</em> with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

  • It measures how many standard deviations the measure is from the mean.  
  • After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem:

  • The mean is of 550, hence \mu = 550.
  • The standard deviation is of 125, hence \sigma = 125.

The proportion of the population considered to be potential leaders is <u>1 subtracted by the p-value of Z when X = 780</u>, hence:

Z = \frac{X - \mu}{\sigma}

Z = \frac{780 - 550}{125}

Z = 1.84

Z = 1.84 has a p-value of 0.9671.

1 - 0.9671 = 0.0329

0.0329 = 3.29% of the population are considered to be potential leaders.

A rectangle has an area of 54 square centimeters. The width is 3 more
Troyanec [42]

Answer:

W = 6

L = 9

Step-by-step explanation:

area = 54 = L x W

L = W + 3

substitute for L:

54 = W(W + 3)

W² + 3W = 54

W² + 3W - 54 = 0

(W + 9)(W - 6) = 0

W = 6

L = 6 + 3 = 9
