I am assuming that you are talking about problem 2. so I will answer that.

Step-by-step explanation:

-2x + 6 ≥ 3x - 34

+2x        +2x

        6 ≥ 5x - 34

      +34       + 34

       40 ≥ 5x

       ÷5    ÷5

        8 ≥ x

So, x can be anything equal to or less than 8.

Answer:

x≤8

For the graph closed circle on 8 with the shading going to to left

Step-by-step explanation:

-2x+6≥3x-34 (given)

Subtract 6 on both sides

-2x≥3x-40

Subtract 3x on both sides

-5x≥-40

Divide by -5 on both sides

x≤8

You are researching the average emails received per day. You want to know how many employees you should survey if you want to know, at a 90% confidence level, that the sample mean emails per day is within 47 emails of the true mean emails per day. From above, we know that the population standard deviation is 155, and z-value is 1.645$_

Answers

Answer:

The value is  [tex]n =29 \ employees [/tex]

Step-by-step explanation:

Generally the number of employee to survey(sample size) is mathematically represented as

       [tex]n = [ \frac{z *  \sigma }{E} ]^2[/tex]

Here E is the margin of error which is given as E = 47

So substituting 1.645 for z and   155 for  [tex]  \sigma[/tex]

     [tex]n = [ \frac{1.645 *  155 }{47} ]^2[/tex]

=>    [tex]n =29 \ employees [/tex]

Answers

Answer:

for A=[tex]\frac{7b-7}{6}[/tex] and for B=[tex]\frac{6a+7}{7}[/tex]

Step-by-step explanation:

For A

[tex]\left(6a-3\right)=\left(7b-10\right)[/tex]

[tex]6a-3+3=7b-10+3[/tex]

[tex]6a=7b-7[/tex]

[tex]\frac{6a}{6}=\frac{7b}{6}-\frac{7}{6}[/tex]

[tex]a=\frac{7b-7}{6}[/tex]

For B

[tex]\left(6a-3\right)=\left(7b-10\right)[/tex]

[tex]7b-10=\left(6a-3\right)[/tex]

[tex]7b-10=6a-3[/tex]

[tex]7b-10+10=6a-3+10[/tex]

[tex]7b=6a+7[/tex]

[tex]\frac{7b}{7}=\frac{6a}{7}+\frac{7}{7}[/tex]

[tex]b=\frac{6a+7}{7}[/tex]

Step-by-step explanation:

2 + 34233 = 34235 - 2943 = 31292 + 291 = 31583 x 45 = 1421235

2 + 34233 = 34235 - 2943 = 31292 + 291 = 31583 ➗ 45 = 701.844444444

If its multiplication the answer is = 1421235

1) On a road map, the distance from Louisville to St. Louis is 12 cm. If the map has
a scale of 2 cm = 20 miles, what is the distance to St. Louis?

Answers

On the scale of 2cm = 20 miles, take 12 Divided by two which will give you 6 Times 20 equals 80 miles

120 miles.

All you have to do to understand this problem is the relationship between the cm and mi.

In this case:

2cm =20mi.

The relationship is times 10, because 2 x 10=20

So multiply 12 by 10, and you will get 120mi.

Therefore, the answer is 120mi.

length 1. What is the area in
square feet of a rug with a
length of 13 feet and width of
6 feet?

Answers

Answer:

78 ft^2

Step-by-step explanation:

A = lw

l = 13 ft

w = 6 ft

A = 13ft  x 6 ft

A = 78 ft^2

Multiply the length by width to find Area. The unit for Area will be feet squared because both the numbers for length and width had the same unit.

-40 = -b

b = 40

Answer:

b = 40

Step-by-step explanation:

-b/4 = - 10              Multiply both sides by 4

-b/4 * 4 = - 10 * 4

- b = - 40               Multiply both sides by -1

(-1) * (-b) = (-40)(-1)

b = 40

Thirteen less than twice a number is fifteen. What is the equation? What is the number?

Answers

2x-13=15 is the equation. The number (x) is 14

Hi there!

Let the unknown number be c.

Twice a number means we multiply that number by 2:

2c

Now, subtract 13:

2c-13

This expression is equal to 15:

2c-13=15

As soon as I added the equal sign, and the number than the expression is equal to, the expression turned into an equation.

Now, let's solve it for c.

2c=15+13

2c=28

c=14
