Answer:

Hi there!

The answer to this question is: A. 55 degrees

Step-by-step explanation:

Using a the triangle angle sum theorem, you know all angles of triangle add up to 180.

In picture you are given two angles, 90 and 35

all you do is add them to get 125

then you subtract 125 from 180 to get 55

so in other words your final answer should be 55

You can advertise that you need a sample of 50 minivan owners, and use them as a representative of the state. But this is biased and has some inaccuracy.

What is the equation of the circle in standard form see attachment

Elodia [21]

Center (-1,1), radius 5 so

$(x - -1)^2 + (y - 1)^2 = 5^2$

$(x+1)^2 + (y-1)^2 = 25$

The heights of adult males in the United States are approximately normally distributed. The mean height is 70 inches (5 feet 10

steposvetlana [31]

Using the normal distribution, it is found that the probability is 0.16.

<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.

In this problem, the mean and the standard deviation are given by, respectively, $\mu = 70, \sigma = 3$ .

The proportion of students between 45 and 67 inches is the p-value of Z when <u>X = 67 subtracted by the p-value of Z when X = 45</u>, hence:

X = 67:

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

$Z = \frac{67 - 70}{3}$

Z = -1

Z = -1 has a p-value of 0.16.

X = 45:

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

$Z = \frac{45 - 70}{3}$

Z = -8.3

Z = -8.3 has a p-value of 0.

0.16 - 0 = 0.16

The probability is 0.16.

When a can of soup is half full it weighs 8kg. when it is two fifths full it weighs 7 kg. what is the weight of the full can?

Sati [7]

14 kg because 2/5 equals 0.4 and 0.1 equals about 1 kg so I add 0.6 which equals 6 kg so i add 8 kg to 6 kg and get 14 kg
