B+c+(c-b)+(b-c). That is your expression.  b 11 c 16
       
          First, let's convert the variables to real numbers:   11+16+(16-11)+(11-16)
             Now, let's solve that equation.                                    11+16+5+(-5)
                      5+(-5) cancels out, so all we have left is:                   27
                That is your perimeter.

What is the height of this triangle? Round your answer to the nearest tenth.
love history [14]

Answer:

5.7

Step-by-step explanation:

pythagorean theorem

A^2 + B^2 = C^2

sub in

A^2 + 7^2 = 9^2

simplify

A^2 + 49 = 81

solve

A^2 = 32

solve further

A = \sqrt{32

use calculator and get:

5.65685

round and get:

<u>5.7</u>

The distribution of SAT II Math scores is approximately normal with mean 660 and standard deviation 90. The probability that 100
gayaneshka [121]

Using the <em>normal distribution and the central limit theorem</em>, it is found that there is a 0.1335 = 13.35% probability that 100 randomly selected students will have a mean SAT II Math score greater than 670.

<h3>Normal Probability Distribution</h3>

In a normal distribution 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.
  • By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation s = \frac{\sigma}{\sqrt{n}}.

In this problem:

  • The mean is of 660, hence \mu = 660.
  • The standard deviation is of 90, hence \sigma = 90.
  • A sample of 100 is taken, hence n = 100, s = \frac{90}{\sqrt{100}} = 9.

The probability that 100 randomly selected students will have a mean SAT II Math score greater than 670 is <u>1 subtracted by the p-value of Z when X = 670</u>, hence:

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

By the Central Limit Theorem

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

Z = \frac{670 - 660}{9}

Z = 1.11

Z = 1.11 has a p-value of 0.8665.

1 - 0.8665 = 0.1335.

0.1335 = 13.35% probability that 100 randomly selected students will have a mean SAT II Math score greater than 670.

creativ13 [48]

Answer:

B

I

Step-by-step explanation:

A triangle's angles must add up to 180

68+90+x=180

158+x=180

22=x

3 and 2 must add up to 180

70+x=180

angle 2= 110

angle 2 and angle 1 have to add up to 180 as well

110+x=180

andgle 1= 70
