Answer:

15 dimes

Step-by-step explanation:

6 quarters = 6 * .25 = 1.50

a dime equals .10

d * .10 = 1.50

Divide each side by .10

d = 1.50/.10

d = 15

15 dimes

Hello!

The equation of a circle is

(x - h)^2 + (y - k)^2 = r^2

Put in the values we know

(x - h)^2 + (y - 7)^2 = 10^2

It went through point (3, -1)

(3 - h)^2 + (-1 - 7)^2 = 100

(3 - h)^2 + (-8)^2 = 100

(3 - h)^2 + 64 = 100

Subtract 64 from both sides

(3 - h)^2 = 36

Take the square root of both sides

3 - h = +6 or -6

Subtract 3 from both sides

-h = 3 or -9

Since h is negative we can multiply both sides by -1 to make it positive

3 = -3 or 9

The answer is B) 9, -3

Hope this helps!

In a recent contest, the mean score was 210 and the standard deviation was 25. a) Find the z-score of John who scored 190 b) Fin

Answer:

a) $Z = -0.8$

b) $Z = 2.4$

c) Mary's score was 241.25.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

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

The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 210, \sigma = 25$
