7 0

Look at your answer choices, most of them could be proportional.. Now if you look at the rest of your answer choices you can see that the only one that doesn't reduce or increase like that is C.

What is -1/2- (-2/5)=

Stolb23 [73]

= -1/2- (-2/5)
= -1/2 + 2/5
find common denominator (2 goes in 10 five times; 5 goes in 10 twice)
= -(5*1)/10 + (2*2)/10
= -5/10 + 4/10
= -1/10

Hope this helps! :)

A dartboard has a diameter of 18 inches.what are its radius and circumference?

sineoko [7]

We know, radius = diameter / 2 = 18 / 2 = 9 in.
Circumference = 2πr = 2π(9) = 18π = 18 * 3.14 = 56.52 in.

Hope this helps!

Answer:

c. 0.136.

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:

$\mu = 110, \sigma = 15$
