Answer:

The correct option is C) the product of 6 and a number y.

Step-by-step explanation:

Consider the provided expression 6y.

Let variable y is an unknown number or quantity.

Algebraic expression is the expression that consists of whole constants, variables and algebraic operations, where the operations are addition, subtraction, division, multiplication etc.

Now consider the provided expression 6y. It can be written as:

6×y

Here the sign × indicates the product.

Thus, the phrase can be 6 times of y or the product of 6 and a number y.

Hence, the correct option is C) the product of 6 and a number y.

Consider random samples of size 50 from a population with proportion 0.15

WITCHER [35]

Answer:

a) Mean = 0.75

b) Standard error = 0.051

c) Yes

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 50

Sample proportion , p = 0.15

a) Mean

$\mu = np = 50(0.15) = 7.5$

b) Standard error

$S.E = \sqrt{\dfrac{p(1-p)}{n}} = \sqrt{\dfrac{0.15(1-0.15)}{50}} = 0.051$

c) Application of central limit theorem

Since the sample size is larger than 30, we cam apply central limit theorem for normal approximation.

Can someone help me with this substitution method for algebra Y=4*-3x 5x-y=22

alexira [117]

$y=4-3x\\
5x-y=22\\\\
5x-(4-3x)=22\\
5x-4+3x=22\\
8x=26\\
x=\dfrac{26}{8}=\dfrac{13}{4}\\\\
y=4-3\cdot\dfrac{13}{4}\\
y=4-\dfrac{39}{4}\\
y=\dfrac{16}{4}-\dfrac{39}{4}\\
y=-\dfrac{23}{4}\\\\
\boxed{(x,y)=\left(\dfrac{13}{4},-\dfrac{23}{4}\right)}$

Can I get some help here?

andrew-mc [135]

Answer:

AB, CB, AC

Step-by-step explanation:

All the angles in a triangle added up equal 180 degrees

Start by finding the measure of angle A

A + 86 + 27 = 180

A + 113= 180

A = 67 degrees

Now order them

86 is greater than 67 and 27 so B is the greatest

27 is less than 86 and 67 so C is the smallest

67 is less than 86 but greater than 27 so A is in the middle

Now for the sides..

AB is opposite angle C so it's the shortest

CB is opposite angle A so it's in the middle

AC is opposite angle B so it's the longest

I hope this helps!!!
