x - 2/5= 7
find out what x is

Answers

Answer:

see below

Step-by-step explanation:

x - 2/5= 7

Add 2/5 to each side

x - 2/5 + 2/5 = 7+2/5

x = 7 2/5

or if

( x-2) /5 = 7

Multiply each side by 5

(x-2) /5 *5 = 7*5

x-2 = 35

Add 2 to each side

x-2+2 = 35+2

x = 37

Answer:

x = 37

or

x = 7 ²/₅

Step-by-step explanation:

x - 2/5= 7

find out what x is

x - 2/5 = 7

x - 2 = 7 (5)

x - 2 = 35

x = 35 + 2

x = 37

--------

or

x - 2/5 = 7

x = 7 + 2/5

x = 7 ²/₅

8.23 A manufacturing company produces electric insulators. You define the variable of interest as the strength of the insulators. If the insulators break when in use, a short circuit is likely. To test the strength of the insulators, you carry out destructive testing to determine how much force is required to break the insulators. You measure force by observing how many pounds are applied to the insulator before it breaks. You collect the force data for 30 insulators selected for the experiment and organize and store these data in Force: 1,870 1,728 1,656 1,610 1,634 1,784 1,522 1,696 1,592 1,662 1,866 1,764 1,734 1,662 1,734 1,774 1,550 1,756 1,762 1,866 1,820 1,744 1,788 1,688 1,810 1,752 1,680 1,810 1,652 1,736 Construct a 95% confidence interval estimate for the population mean force. What assumption must you make about the population distribution in order to construct the confidence interval estimate in (a)

Answers

Answer:

The 95% confidence interval estimate for the population mean force is (1691, 1755).

Step-by-step explanation:

According to the Central Limit Theorem if we have an unknown population with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from the population with replacement, then the distribution of the sample mean will be approximately normally.

The sample selected here is n = 30.

Thus, the sampling distribution of the sample mean will be normal.

Compute the sample mean and standard deviation as follows:

[tex]\bar x=\frac{1}{n}\sum x=\frac{1}{30}\times 51702=1723.4\\\\s=\sqrt{\frac{1}{n-1}\sum (x-\bar x)^{2}}=\sqrt{\frac{1}{30-1}\times 232561.2}=89.55[/tex]

Construct a 95% confidence interval estimate for the population mean force as follows:

[tex]CI=\bar x\pm z_{\alpha /2}\times\frac{s}{\sqrt{n}}[/tex]

    [tex]=1723.4\pm 1.96\times\frac{89.55}{\sqrt{30}}\\\\=1723.4\pm 32.045\\\\=(1691.355, 1755.445)\\\\\approx (1691, 1755)[/tex]

Thus, the 95% confidence interval estimate for the population mean force is (1691, 1755).

Step-by-step explanation:

If the sum of two consecutive even integers ‘a’ and ‘b’ is k, what is the sum of the next two consecutive integers greater than ‘b’ in terms of k?

Answers

Answer:

We have two consecutive even integers:

a and b.

We know that we can write a even integer as:

a = 2*n

where n is an integer.

Then the consecutive integer to a, b, will be:

b = 2*n + 2.

Then the sum of a and b is:

a + b = 2n + 2n + 2 = 4*n + 2 = 2*(2n + 1) = k.

The next two consecutive integers greater than b will be:

c = 2n + 4

d = 2n + 6

then:

c + d = (2n + 4) + (2n + 6) = 4n + 10 = k + 4.

64-10

54

Answer:

Here's how to solve this.

Step-by-step explanation:

a=5 b=5 c=8

so

3*8 + 5*8 - 2*5

Well 3*8=24

5*8= 40

2*5=10

Therefore 24 + 40 - 10.

24 + 40= 64

64 - 10= 54

would be your answer.

Five time a number plus nine is less than or equal to six times the number plus 5?

Answers

Answer:

1.  Let x = #

2.  "Five less than six times a number" can be written as:  6x - 5

3.  "is at least" is the same as "greater than or equal to" and can be written as:  >=

4.  "nine subtracted from two times that number"  can be written as:  2x - 9

5.  the equation is: 6x - 5 >= 2x - 9

6.  solve for x by grouping the x variable terms on one side and the constants on the other side:

             6x - 5 >= 2x - 9

            -2x +5     -2X +5

             4x      >=      -4    

7.  divide each side by 4, and you get: x = -1

Step-by-step explanation:

Company A sells hats for $11 per hat plus a fixed $7 shipping and handling fee. Company B sells hats for $8 per hat plus
a fixed $16 shipping and handling fee. The marketing director of company A wants to set up a system of equations to find
the number of hats for which the total cost of an order for the two companies is the same. He uses the variables x and y.
He lets y represent the total cost of an order. What will x represent?
O x = total cost of an order
O x = shipping costs for company B
O x = shipping costs for company A
O x= number of hats

Answers

Answer:

Its D

Step-by-step explanation:

x represents the number of hats.

What are Systems of equations?

Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.

Given, Company A sells hats for $11 per hat plus a fixed $7 shipping and handling fee. Company B sells hats for $8 per hat plus a fixed $16 shipping and handling fee.

Let x be the number of hats and y be the total cost for x hats

For Company A:

per hat charges = 11

charge for x hats = 11 * x

Since, shipping charges = 7

Thus,

Total cost for x hats, y = 11x + 7

For Company B:

per hat charges = 8

charge for x hats = 8 * x

Since shipping charges = 16

Thus,

Total cost for x hats, y = 8x + 16

If the Cost is the same,

11x + 7 = 8x + 16

3x = 9

x = 3

therefore, If we order 3 hats then the cost from both companies will be the same. and x represents the number of hats.
