Answer: x= -3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(x−4)+3x−9x=6−(2x+5)+8x

(5)(x)+(5)(−4)+3x+−9x=6+−2x+−5+8x(Distribute)

5x+−20+3x+−9x=6+−2x+−5+8x

(5x+3x+−9x)+(−20)=(−2x+8x)+(6+−5)(Combine Like Terms)

−x+−20=6x+1

−x−20=6x+1

Step 2: Subtract 6x from both sides.

−x−20−6x=6x+1−6x

−7x−20=1

Step 3: Add 20 to both sides.

−7x−20+20=1+20

−7x=21

Step 4: Divide both sides by -7.

Answer:

a

The 95% confidence interval is [tex]1003 < \mu <1023[/tex]

b

Yes there is statistically significant evidence that students in Florida perform differently from other students in the United States

Step-by-step explanation:

From the question we are told that

   The population mean is  [tex]\mu = 1000[/tex]

   The sample size is  [tex]n = 453[/tex]

   The sample mean is  [tex]\= x = 1013[/tex]

    The standard deviation is [tex]s = 108[/tex]

Given that the confidence level is  95% then the level of significance is mathematically represented as

            [tex]\alpha = 100 - 95[/tex]

=>         [tex]\alpha = 5\%[/tex]

=>          [tex]\alpha = 0.05[/tex]

The critical value  for [tex]\frac{\alpha }{2}[/tex] obtained from the normal distribution table is          

          [tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]

Generally the margin of error is mathematically represented as

         [tex]E = Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{n} }[/tex]

=>     [tex]E = 1.96 * \frac{108}{\sqrt{453} }[/tex]

=>      [tex]E = 9.946[/tex]

Generally the 95% confidence interval is mathematically represented as

           [tex]\= x - E < \mu < \= x + E[/tex]

=>         [tex]1013 - 9.946 < \mu < 1013 + 9.946[/tex]

=>         [tex]1003 < \mu <1023[/tex]

Given that the population mean(1000) is not within the 95% confidence interval for l for the average test score for students in Florida, then it means that there is statistically significant evidence that students in Florida perform differently from other students in the United States

Answer:

The value is  [tex]\r p  =  2.9\%[/tex]

Step-by-step explanation:

From the question we are told that

Answer:

Step-by-step explanation:

In this problem, we are expected to estimate the number of bricks he can set in 8 hours.

let us convert hours to minutes we have

60 min make 1 hour

x min make 8 hours

cross multiply

x= 60*8

x= 480 min

We are assuming the same rate with which he sets 2.5 brick is the same as the rate with which he will set bricks for the 8 hours windows

so if the bricklayer sets

2.5 bricks in 1min

y bricks in 480 min

Cross multiply we have

y=2.5*480

y= 1200  bricks

hence in 8 hours, he will set 1200 bricks

Answer:

Parker>Richard

Step-by-step explanation:

So we know Parker has 12 marbles(blue) and Richard has 3/4(.75) of that.

You do not need multiplication as the answer is above this

Come on look above, what do you see?

Richard has .75 or 75% or 3/4 but not 1 or higher so he has less

Answer: Parker>Richard

The number of marbles Parker has > the Number of marbles Richard has.

Parker has 12 blue markers.

Richard has 3/4 of the blue marbles that Parker has.

A fraction represents a part of a whole or, more generally, any number of equal parts.

For example, when We say 3/4, it means there will be 4 equal parts out of which we are considering 3 parts.

Same way, Richard has 3/4 of the blue marbles that Parker has.

This means Parker has 4 equal parts of 12 marbles.

This means Parker has 4 equal parts with each part consisting of 3 marbles.

Since each part contains 3 marbles

So 3 parts will contain 3+3+3 =9 marbles

Since Richard has 3 parts of the blue marbles that Parker has.

This means Richard has 9 marbles.

Therefore, the Number of marbles Parker has > the Number of marbles Richard has.

Answer:

[tex]x = \frac{8d-10e-3a-2b}{c}[/tex]

Step-by-step explanation:

In order to find x, our goal is to isolate it on one side of the equation.

To do this, let's first apply the distributive property on the right side of the equation.

[tex]3a+2b+cx = 8d - 10e[/tex]

Now we can subtract [tex]3a[/tex] and [tex]2b[/tex] from both sides:

[tex]cx = 8d - 10e - 3a - 2b[/tex]

And now we can divide both sides by [tex]c[/tex] so that x is alone on the left side.

[tex]x = \frac{8d-10e-3a-2b}{c}[/tex]

Answer: 5 or 55

Step-by-step explanation:

The remainder is 98 when 7842 is divided by 176 after using the arithmetic operation.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have two numbers:

7842 and 176

7842 is divided by 176

Mathematically,

= 7842 ÷ 176

We can write the above number expression in the form of a fraction:

= 7842/176

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The remainder will be:

Quotient = 44

Remainder = 98

Thus, the remainder is 98 when 7842 is divided by 176 after using the arithmetic operation.

Answer:

x = 21

Step-by-step explanation:

Step 1: Write out equation

-5x - 72 = -12x + 75

Step 2: Add 5x to both sides

-72 = -7x + 75

Step 3: Subtract 75 on both sides

-147 = -7x

Step 4: Divide both sides by -7

21 = x

Step 5: Rewrite

x = 21

Answer:

Step-by-step explanation:

1. perp. 1/2

y - 2 = 1/2(x - 4)

y - 2 = 1/2x - 2

y = 1/2x

2. 2y = -4x + 8

   y = -2x + 4

   perp. 1/2

  y - 2 = 1/2(x - 6)

  y - 2 = 1/2x - 3

  y = 1/2x - 1

3. perp. -3/2

 y - 2 = -3/2(x - 2)

  y - 2 = -3/2x + 3

   y = -3/2x + 5

4. perp. -4

y - 8 = -4(x - 2)

y - 8 = -4x + 8

y = -4x + 16

Answer: (2,-3)

Step-by-step explanation:

To solve by elimination method, we need to choose which variable to eliminate. Let's eliminate y. We need to make sure that the y coefficients in both equations are equal. To do that, you multiply the first equation by 5 and the second by 9.

(11x + 9y = -5)5        [multiply entire equation by 5]

(7x + 5y = -1)9          [multiply entire equation by 9]

--------------------------------------------------------------------------------------------------------

55x+45y=-25

63x+45y=-9

Now that the y are both the same, we can eliminate y by subtracting both equations and solve.

-8x=-16                     [divide both sides by -8]    

x=2

Now that we have x=2, we can plug that in to any equation to find y.

7(2)+5y=-1                [multiply]

14+5y=-1                   [subtract both sides by 14]

5y=-15                      [divide both sides by 5]

y=-3      

With the y-value, we know that the answer is (2,-3).
