132+x=180

x=180-132

x=48

Answer:

48 DEGREES

Step-by-step explanation:

First you need to find the other two angles : 42 + 90 = 132 ( the 90 comes from the little square like shape on the other angle).

So x = 180 - 132 = 48 ( we use 180 because it is the sum of interior angles of a triangle.

Question: On this dartboard, the circle with 1-m radius is inscribed in an equilateral triangle. Find the probability that a dart that hits the board lands in the circular region. Justify your answer.

Let's start by finding the length of one of the sides of the equilateral triangle. We can do this by creating a 30-60-90 triangle from the radius of the inscribed circle.

I attached an image of what this should look like.

Solving for the length of half of the base of the equilateral triangle gives us 1√3. To get the length of the entire base of the triangle, we will double this value:

s = 2√3

The area of an equilateral triangle is [tex]\displaystyle A=\frac{s^2 \sqrt{3} }{4}[/tex].

We can substitute the known value of s (side length) into the formula and solve for A.

[tex]\displaystyle A_t=\frac{(2\sqrt{3})^2\cdot \sqrt{3} }{4}[/tex] [tex]\displaystyle A_t=\frac{4(3) \cdot \sqrt{3} }{4}[/tex] [tex]\displaystyle A_t=3\sqrt{3}[/tex]

The area of the equilateral triangle is 3√3.

Now, let's solve for the area of the inscribed circle. The formula for the area of a circle is [tex]\displaystyle A= \pi r^2[/tex].

We know the radius of the circle is 1, so let's substitute 1 for r:

[tex]A_c= \pi (1)^2[/tex] [tex]A_c=\pi[/tex]  

The area of the inscribed circle is π.

To find the probability of the dart hitting a specific area on the dartboard, we will divide the desired area by the total area of the dartboard.

[tex]\displaystyle P=\frac{\text{Desired area}}{\text{Total area}}[/tex] [tex]\displaystyle P=\frac{\pi}{3\sqrt{3} }[/tex] [tex]\displaystyle P=\frac{\pi \sqrt{3} }{9}[/tex] [tex]P \approx 0.60459978[/tex]

The probability that a dart that hits the board lands in the circular region is about 60.46%.

The weights of a certain brand of candies are normally distributed with a mean weight of 0.8544 g and a standard deviation of 0.0525 g.

If 1 candy is randomly​ selected, find the probability that it weighs more than 0.8535 g. The probability is:_____

Answers

Answer:

The probability is 0.508 = 50.8%.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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 p-value, we get the probability that the value of the measure is greater than X.

Normally distributed with a mean weight of 0.8544 g and a standard deviation of 0.0525 g.

This means that [tex]\mu = 0.8544, \sigma = 0.0525[/tex]

If 1 candy is randomly​ selected, find the probability that it weighs more than 0.8535 g.

This is 1 subtracted by the pvalue of Z when X = 0.8535. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{0.8535 - 0.8544}{0.0525}[/tex]

[tex]Z = -0.02[/tex]

[tex]Z = -0.02[/tex] has a pvalue of 0.492

1 - 0.492 = 0.508

The probability is 0.508 = 50.8%.

Normally distributed

Please give me brainliest, I really need it.

a)As the number of surveys increases, the mean of the sample means will approach the population mean.

b)Means will be normally distributed.

What is a normal distribution?

A normal distribution is a probability distribution that is symmetric about the mean, and data near the mean are more frequent than data far from the mean.

As the number of surveys increases, we will have more data.

So, the mean of the sample means will approach the population mean.

Means will be normally distributed because each survey has the same number of respondents.

Thus, a)as the number of surveys increases, the mean of the sample means will approach the population mean.

b)Means will be normally distributed.

Step-by-step explanation:

All parallel lines will meet their transversal (the line going through them) at the same angle. We can imagine sliding line m up to line l until the two are overlapping, and naturally all of those angles at the intersection will overlap, too. ∠6 will overlap ∠2, so the two angles are congruent. If m∠6 = 75°, then m∠2 = 75°!

Find the probability that when a couple has five children, at least one of them is a boy. (assume that boys and girls are equally likely.)​

Answers

Answer:

The easiest way to figure this is to find P(no girls in 5 births) = (1/2)^5 = 1/32 -------------- The P(at least one girl in 5 births) = 1 - 1/32 = 31/32

The probability that when they have five children, at least one of them is a boy is 31/32

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome:

The probability that a couple will have a boy or girl among the five children = 1/2

If they gave birth to 5 children:

The probability that when they have five children, at least one of them is a boy = 1 - (1/2)^n where:

n is the total number of children

The probability that when they have five children, at least one of them is a boy = 1 - (1/2)ⁿ

The probability that when they have five children, at least one of them is a boy = 1 - (1/2)⁵

The probability that when they have five children, at least one of them is a boy = 1- 1/32 = 31/32

Hence the probability that when they have five children, at least one of them is a boy is 31/32
