A circle is inscribed in a square. A point in the figure is selected at random. Find the probability that the point will be in t

hram777 [196]

P of selecting point on the shaded region = shaded area/whole area
P( selecting point on the shaded ) = ( the four shaded circles ) / the whole square 
P of selecting point on the shaded = ( 4 * ( π * r^2 ) )/ x^2 
P of selecting point on the shaded = ( 4 * ( π * (x/4)^2 ) )/ x^2 
P of selecting point on the shaded = ( 4 * ( π * x^2/16 ) )/ x^2 
P of selecting point on the shaded = ( π * x^2/4 )/ x^2 
P of selecting point on the shaded = x^2( π/4 )/ x^2 
P( selecting point on the shaded ) = π/4 ≈ 0.7854 ≈ 79%
=80%

When Julio cracked open his piggy bank, he

jok3333 [9.3K]

Answer:

52 quarters, 42 dimes

Step-by-step explanation:

Let's call the number of quarters q, and the number of dimes d.

q+d=94

0.25q+0.1d=17.20

Subtract q from both sides of the first equation to isolate d:

d=94-q

0.25q+0.1(94-q)=17.20

0.25q+9.4-0.1q=17.20

0.15q=7.8

q=52

d=94-q=42

Hope this helps!

A researcher conducted an experiment to investigate the effectiveness of a medicated lotion in treating a skin irritation. A gro

Helga [31]

Answer:

It can be concluded that the medicated lotion has an effect on treating skin irritations.

Step-by-step explanation:

In this case we need to determine whether the medicated lotion was effective in treating the skin irritation or not.

The hypothesis can be defined as follows:

H₀: There is no difference between the two proportions, i.e. p₁ - p₂ = 0.

Hₐ: There is a significant difference between the two proportions, i.e. p₁ - p₂ ≠ 0.

The information provided is:

n₁ = 40

n₂ = 40

X₁ = 36

X₂ = 16

Compute the sample proportions and total proportions as follows:

$\hat p_{1}=\frac{36}{40}=0.90\\\\\hat p_{2}=\frac{16}{40}=0.40\\\\\hat P=\frac{X_{1}+X_{2}}{n_{1}+n_{2}}=\frac{36+16}{40+40}=0.65$

Compute the test statistic value as follows:

$z=\frac{\hat p_{1}-\hat p_{2}}{\sqrt{\hat P(1-\hat P)[\frac{1}{n_{1}}+\frac{1}{n_{2}}]}}=\frac{0.90-0.40}{\sqrt{0.65(1-0.65)[\frac{1}{40}+\frac{1}{40}]}}=4.69$

The test statistic value is 4.69.

The decision rule is:

The null hypothesis will be rejected if the p-value of the test is less than the significance level.

Compute the p-value as follows:

$p-value=2\times P(Z$

The p-value of the test is very small.

The null hypothesis will be rejected at any significance level.

Thus, there is a significant difference between the two proportions.

So, it can be concluded that the medicated lotion has an effect on treating skin irritations.
