[Right Triangle Only] sin∅ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Define

We have a right triangle. We can use trig to find the angle.

Step 2: Identify Variables

Angle = x

Opposite = 15

Hypotenuse = 23

Step 3: Find Angle x

Substitute: sinx° = 15/23
Inverse: x° = sin⁻¹(15/23)
Evaluate: x = 40.7057°

A simple random sample of size n=10 is obtained from a population that is normally distributed with a mean of 40 and a standard

Eva8 [605]

Yes, the sampling distribution is normally distributed because the population is normally distributed.

A sampling distribution is a chance distribution of a statistic obtained from a larger variety of samples drawn from a specific populace. The sampling distribution of a given population is the distribution of frequencies of a variety of various outcomes that would probable occur for a statistic of a populace.

A sampling distribution is a probability distribution of a statistic this is obtained via drawing a huge variety of samples from a particular populace. Researchers use sampling distributions so that you can simplify the technique of statistical inference.

Solution :

mean = μ40

standard deviation σ σ= 3

n = 10

μx = 40

σ x = σ√n = 3/√10 = 0.9487

μ x = 4σ\x = 0.9487

σx = 0.9487

Yes, the sampling distribution is normally distributed because the population is normally distributed.

Chang knows one side of a triangle is 13 cm. Which set of two sides is possible for the lengths of the other two sides of th

Keith_Richards [23]

Answer:

8 cm and 9 cm

Step-by-step explanation:

The other two sides added together have to equal a larger number than 13, since 13 is the largest side.

5 + 8 = 13

6 + 7 = 13

7 + 2 = 9

8 + 9 = 17

Solve 4 square root of 3 = 8cos

sukhopar [10]

Therefore $\theta = 30^\circ$

Step-by-step explanation:

Given,

$4\sqrt{3 } =8 cos \theta$

$\Leftrightarrow cos \theta =\frac{4\sqrt{3} }{8}$

$\Leftrightarrow cos \theta =\frac{\sqrt{3} }{2}$

$\Leftrightarrow cos \theta =cos 30^\circ$

$\Leftrightarrow \theta = 30^\circ$

Therefore $\theta = 30^\circ$

Andre wants to save $40 to buy a gift for his dad. Andre’s neighbor will pay him weekly to mow the lawn, but Andre always gives

kirill115 [55]

Answer:

Andre’s neighbor pays him $ 10 each week to mow the lawn

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Cost of Andre's dad gift = $ 40

Weekly donation to the food bank = $ 2

Number of weeks to save $ 40 = 5

2. How much does Andre’s neighbor pay him each week to mow the lawn?

Let's calculate this amount, this way:

Weekly payment = [Cost of the gift + (Weekly donation * Number of weeks to save)]/Number of weeks

Replacing with the real values we know:

Weekly payment = [40 + (2 * 5)]/5

Weekly payment = 50/5 = 10

Andre’s neighbor pays him $ 10 each week to mow the lawn
