Answer:

hahaha

ok so 70=z

a line is 180 degrees

so 180-70 is 110

so set the 4x+12 = 110

solve for x

u figure that out i don' t feel like doing that rn

once you find x

input it into 3x

get an answer

then add z (z is 70, from the beginning) to the answer u just got

and then ur gonna take that answer and subtract it from 180 degrees(3 angles of a triaNile add to 180 degrees)

then u should get you answer

have a nice day and stay safe

hope this helps

Answer:

The answer to your question is below

Step-by-step explanation:

2. \sqrt{-128}                Just find the prime factors of 128 and simplify

   \sqrt{-2^{7}} = \sqrt{-2^{6} 2} = 2^{3}i \sqrt{2}

   8i\sqrt{2}

3.- \sqrt{-9} + \sqrt{-16}     Get the square roots and simplify

     3i + 4i

     7i

4.- None of the choices is equal to one, because the exponents are pair.

5.- 1/3x² + 10 = 7

    1/3x² = 7 - 10

    1/3x² = -3

         x² = -3(3)

         x² = -9

         x = ±3i

A recent study from the University of Virginia looked at the effectiveness of an online sleep therapy program in treating insomn
Ludmilka [50]

Answer:

1. The 99% confidence interval for the difference in average is -6.47377 < μ₁ - μ₂ < -11.34623

2. The possible issues in the calculations includes;

a. The confidence level used in the confidence interval can influence the result of the confidence interval observed

b. The sample size is small

Step-by-step explanation:

1. The number of adults with insomnia in the sample = 45

The number of adults that participated in the therapy, n₁ = 22

The number of candidates that served as control group, n₂ = 23

The average score for the for the 22 participants of the program, \overline x_1 = 6.59

The standard deviation for the 22 participants of the program, s₁ = 4.10

The average score for the for the 23 subjects in the control group, \overline x_2 = 15.50

The standard deviation for the 23 subjects in the control group, s₂ = 5.34

The confidence interval for unknown standard deviation, σ, is given by the following expression;

\left (\bar{x}_{1}- \bar{x}_{2}  \right )\pm t_{\alpha /2}\sqrt{\dfrac{s_{1}^{2}}{n_{1}}+\dfrac{s_{2}^{2}}{n_{2}}}

α = 1 - 0.99 = 0.01

α/2 = 0.005

The degrees of freedom, df = 22 - 1 = 21

t_{\alpha /2} = t_{0.005, \, 21} = 1.721

Therefore, we have;

\left (6.59- 15.5  \right )\pm1.721 \cdot \sqrt{\dfrac{4.10^{2}}{22}+\dfrac{5.34^{2}}{23}}

The 99% confidence interval for the difference in average is therefore given as follows;

-6.47377 < μ₁ - μ₂ < -11.34623

Therefore, there is considerable evidence that the participants in the survey  had lower average score than the subjects in the control group

2. The possible issues in the calculations are;

a. The confidence level used in the confidence interval can influence the result of the confidence interval observed

b. The sample size is small
