Answer:

Step-by-step explanation:

From the Pythagorean Theorem

a^2 + b^2 = c^2

a = 1

b = ?

c = 2

1^2 + b^2 = 2^2

1 + b^2 = 4

b^2 = 4 - 1 = 3

b = sqrt(3)

Tan(30) = opposite / adjacent.

adjacent = sqrt(3)

Tan(30) = 1/sqrt(3)

=========

If you need a decimal, it is

1 / 1.321

tan 30 = 0.5774

Name a point that is not coplanar with points A, B, and C.
boyakko [2]
Points are coplanar if they are located on the same plane. A plane is one of the undefined terms in geometry. It is described as a flat surface in a two-dimensional area. If you look at the given figure, find points that are not included in the shaded plane of points A, B and C. That would be point M or point D.

We have a null hypothesis that u=3.75, but we are reluctant to accept this as the population value in case the true value is dif
Gala2k [10]

Answer:

option A

Step-by-step explanation:

To Test

H₀ : μ = 3.75            

H₁ : μ ≠ 3.75                

now,                                        

If μ = 3.95 then it means H₀ is not true.                  

then the probability is rejecting the null hypothesis.        

Hence, the probability is the power of the test against the alternative μ=3.95                      

The correct answer is option A

Jamal states that ax + b = a(x + c), given a, b, and c are not equal to 0. What must be the value of c for Jamal's statement to
Anna35 [415]

ANSWER

For Jamal statement to be true,

c = \frac{b}{a}

EXPLANATION

The given statement is:

ax + b = a(x + c)

We expand the left hand side to obtain,

ax + b = ax + ac

Subtract ax from from both sides of the equation.

b=ac

We know that, a≠0 , so we can divide through by 'a'.

\frac{b}{a}  = c
