Answer:

Step-by-step explanation:

The trick here is to know PEMDAS.

PEMDAS stands for: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

This is the order in which you should simplify a problem.

Parentheses:

(5 + 1)^2 - (11 + 32) + 4

(6)^2 - (43) + 4

Exponents:

(6)^2 - (43) + 4

36 - 34 + 4

We have no multiplication or division, so we can skip those steps.

Addition:

36 - 34 + 4

40 - 34

Subtraction:

40 - 34

So 6 is our answer.

∠C and ∠D are vertical angles with m∠C=−3x+58 and m∠D=x−2 . What is m∠D ?

Y_Kistochka [10]

So we have to find out what x is before we can solve for either angle

because vertical angles are always congruent we can set the two equations to equal each other and solve for x

-3x + 58 = x - 2

we need to get all the x terms on one side before we can solve for x so let's add 2 to both sides to get x alone on the right side

now we have

-3x + 60 = x

now we add 3x to both sides

60 = 4x

we isolated the terms and now we can solve for x by dividing both sides by 4

15 = x

so if x = 15 we need to plug that in to both equations to check our work

C = -3(15) + 58

C = 13

D = 15 - 2

D = 13

x does in fact equal 15 because both equations got the same answer and we found out that angle D = 13

population mean =72 and standard deviation =10, what is standard error of distribution of sample means for n=4 and n=25

mixer [17]

Answer:

The standard error of distribution for n = 4 is 5 and for n = 25 is 2.

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Population mean = 72

Standard deviation = 10

Sample₁ = 4

Sample₂ = 25

2. For finding the standard error of the mean, we use the following formula:

Standard error = Standard deviation / √Size of the sample

Standard error for Sample₁ = 10/√4

Standard error for Sample₁ = 10/2 = 5

Now, let's find the standard error for Sample₂

Standard error for Sample₂ = 10/√25

Standard error for Sample₂ = 10/5 = 2
