Answer:

34

Step-by-step explanation:

<u>We have to find the value of the expression ( 4x - 2y ).</u>

Also, given that,

x = 7

y = -3

<u>So, to find the value of the given expression, you have to replace x and y with 7 & -3 respectively.</u>

<em>Let us solve it now.</em>

4x - 2y

4 × 7 - 2 × -3

28 + 6

<u>34</u>

Please solve, 1-8n-8= -7n-6n-12?​
Marta_Voda [28]

Answer:

n = -1

Step-by-step explanation:

1 - 8n - 8 = -7n - 6n - 12

Simplify

-8n - 7 = -13n - 12

Add 7 to both sides

-8n = -13n - 5

Add 13n to both sides

5n = -5

Divide both sides by 5

n = -1

Tina is joining 3 sections of a quilt. Each section has 3 rows of 15 square pieces of fabric. How many squares will be in the co
Tomtit [17]

Answer: There are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.

Step-by-step explanation:

Since we have given that

Number of sections = 3

Number of rows in each sections = 3

Number of square pieces in each row = 15

So, the number of squares that will be in the completed quilt would be

3\times 3\times 15\\\\=9\times 15\\\\=135

Hence, there are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.

Suppose commute times in a large city are normally distributed and that 63.70% of commuters in this city take more than 22 minut
USPshnik [31]

Answer:

The mean is 24.205

Step-by-step explanation:

Firstly, we need to get the z-score

From the question, the probability we have is the probability that commuters take more than 22 minutes to commute one-way

So the probability we had was;

P( x > 22)

So we need the z-score corresponding to 63.70% or simply 0.637

We can use the standard normal distribution table to get this

Mathematically, from the standard normal distribution table this is -0.35

z-score = (x- mean)/SD

-0.35 = (22-mean)/6.3

22-mean = -2.205

mean = 22 + 2.205 = 24.205
