Find the length of "a", to<br> the nearest tenth, using<br> the Pythagorean Theorem.<br> Enter
bearhunter [10]

Answer:

\sqrt{28} \approx 5.3

Step-by-step explanation:

The Pythagorean Theorem says if you have a right triangle, then relationship between the three sides is the sum of the square of each leg is the hypotenuse squared.

So a^2+b^2=c^2

where a and b are legs and c is the hypotenuse.

Plug in your a,b, and c. In this case it is a,6, and 8.

This means we have

a^2+6^2=8^2

Simplify where you can before we begin the solving (the moving around of things to other sides).

a^2+36=64

Now time for the solving. We are first going to get a^2 by itself.

To do this, we just need to subtract 36 on both sides giving us:

a^2=64-36

a^2=28

Now to get rid of the square on a, just square root both sides:

a=\sqrt{28}.

Find the slope of the line that passes through each pair of points (8,2) (8, -1)
mash [69]

Answer:

Undefined

Step-by-step explanation:

Use the following formula to solve for slope:

\frac{y_2-y_1}{x_2-x_1} =m

m=\frac{(-1)-2}{8-8}

m=\frac{-3}{0}

The equation is not a function and therefore the slope is undefined because there are multiple y values for a single x value.

Suppose that IQ scores have a bell-shaped distribution with a mean of 95 and a standard deviation of 15. Using the empirical rul
professor190 [17]

Answer:

2.5% of IQ scores are no more than 65

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 95

Standard deviation = 15

Using the empirical rule, what percentage of IQ scores are no more than 65?

65 = 95 - 2*15

So 65 is two standard deviations below the mean.

By the Empirical Rule, 95% of the measures are within 2 standard deviation of the mean. Of those 5% which are not, 2.5% are more than 2 standard deviations above the mean and 2.5% are more than 2 standard deviations below the mean.

So 2.5% of IQ scores are no more than 65
