Answer:

Below in BOLD.

Step-by-step explanation:

1. x^2 = 3^2 + 6^2

x^2 = 9 + 36 = 45

x = √45

x = 3√5.

2. 15^2 = x^2 + 12^2

x^2 = 15^2 - 12^2 = 225 - 144 = 81

x = 9.

9, 10 and 15 are Pythagorean triplets.

3. x^2 = 10^2 - 6^2 = 64

x = 8.

6, 8 and 10 are Pythagorean triplets.

Answer:

 -1

Step-by-step explanation:

here's your solution

=> The value of x = 1

=> The value of y = 2

=> we need to find ( x - y)

=> so, put the value of above variables in it

=> hence, (1 - 2) = - 1

=> - 1 is correct answer

hope it helps

As part of his semester project, a BYU-Idaho Introductory Statistics student calculates a 95% confidence interval for the true p

lyudmila [28]

Answer:

a. There's a 95% chance that the true proportion is in the confidence interval.

Step-by-step explanation:

When we want to estimate a property of a population (a population's parameter), without surveying the population, we use samples.

Then, with the information of the samples we can calculate the statistics and infere properties about a population. This inferences obviously came with some uncertainty, depending on the properties of the sample and specially the sample size.

When we talk about confidence intervals, we use the statistic of the sample (in this case, the mean) to estimate a range of values it is expected to find the true mean of the population. The width of this interval depends on the sample standard deviation and the sample size.

The value of the confidence interval (95%, 99%, etc) represent the probabilty that the true mean is within this interval.

On Planet Galactica, common units of distance are alpha, beta, and gamma. 4 gammas equal 5 betas. 2 betas equal 3 alphas. How ma

siniylev [52]

Answer:

15/8 alphas = 1 gamma

Step-by-step explanation:

4 gammas = 5 beta

beta = 4/5 • gamma

2 betas = 3 alphas

beta = 3/2 • alpha

beta = beta

4/5 • gamma = 3/2 • alpha

multiply each side by 5/4

5/4 • 4/5 • gamma = 5/4 • 3/2 • alpha

gamma = 15/8 • alpha

Answer:

2. Find m

sin m˚ = 2/5

sin^-1 (2/5) = m˚

m˚ = 23.57˚

3. Sine law

$\frac{8}{sin103}=\frac{5}{sin\alpha }$

$\frac{5sin103}{8}=sin^{-1}(0.608)=37.5$
