Answer:

y = 2(x-3)

Step-by-step explanation:

This is because Gavin representing "x" loses 3 marbles, which is shown by the -3 in the parenthesis, is half of what Cindy has, or as the problem says "Cindy has double the marbles that Gavin has." These two together result in y=2(x-3)

Answer:

50 kilometers

Step-by-step explanation:

All you need to do to solve is plug in 4.5 into x: y=10(4.5)+5. First you multiply 4.5 by 10 to get 45. Then, you add 5 to 5 to get 50.

Answer:

B

Step-by-step explanation:

Step one: 1/2 * 2 = 1

The reason for this step is to make it 1 full cup of tomatoes like it says in the problem.

Step two: 1/8 * 2 = 2/8 = 1/4

The reason for this step is because you doubled the cup of tomatoes so you have to double the cup of onions.

Answer:

Lesser x = -7

Greater x = 7

Step-by-step explanation:

g(x)= -10x² + 490

don't ask me Khan academy says so

Answer:

lesser x=-7 greater x=7

Step-by-step explanation:

use algebra to find x^2 by itself

x^2 =49

now take the square root of booth sides, both positive and negative

and you have your answer

The inequality is 12x + 18y ≥ 500 and , where x is the number of hours mowing lawns and y is the number of hours shoveling field

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the number of hours mowing lawns be x

Let the number of hours shoveling field be y

And , the amount earned per hour for mowing lawns = $ 12

So , for x hours , the amount earned = 12x

The amount earned per hour for shoveling = $ 18

And , for y hours , the amount earned = 18y

The minimum amount Liam should earn = $ 500

And , the inequality is

12x + 18y ≥ 500

Therefore , the value of A is 12x + 18y ≥ 500

Hence , the inequality equation is 12x + 18y ≥ 500

Answer:

     The decision rule is  

Reject the null hypothesis

        The conclusion is

There is no sufficient evidence to show that the claim that the vinyl gloves have a greater virus leak rate than latex gloves

Step-by-step explanation:

From the question we are told that

   The sample size of vinyl gloves [tex]n_1 = 216[/tex]

   The sample size of latex gloves is [tex]n_2 = 216[/tex]

   The sample proportion  of vinyl gloves that leaked virus is [tex]\^ p_1 = 0.68[/tex]

   The sample proportion of latex gloves that leaked virus is  [tex]\^ p_2 = 0.06[/tex]

    The significance level is  [tex]\alpha =0.05[/tex]

The  null hypothesis is [tex]H_o : p_1 = p_2[/tex]

The alternative hypothesis is  [tex]H_a: p_1 > p_2[/tex]

Generally the number of vinyl gloves that leaked virus is

        [tex]x_1 = \^ p_1 * n_1[/tex]

=>     [tex]x_1 = 0.68 * 216[/tex]

=>     [tex]x_1 = 146.88[/tex]

Generally the number of latex gloves that leaked virus is

        [tex]x_2 = \^ p_2 * n_2[/tex]

=>     [tex]x_2 = 0.06 * 216[/tex]

=>     [tex]x_2 = 12.96[/tex]

Generally the pooled population proportion is mathematically represented as

               [tex]\^ p = \frac{x_1 + x_2}{ n_1 + n_2}[/tex]

=>            [tex]\^ p = \frac{146.88 +12.96 }{ 216 + 216}[/tex]

=>            [tex]\^ p = 0.37[/tex]

Generally the test statistics is mathematically represented as

            [tex]z = \frac{ \^ p_1 - \^ p_2}{ \sqrt{\^ p (1- \^ p ) [\frac{1}{n_1} + \frac{1}{n_2} ]} }[/tex]

=>         [tex]z = \frac{ 0.68 - 0.06}{ \sqrt{0.37 (1- 0.37 ) [\frac{1}{216} + \frac{1}{216} ]} }[/tex]

=>         [tex]z =13.35[/tex]

From the z table  the area under the normal curve to the right  corresponding to  13.35  is

     [tex]P( Z > 13.35) = 0.00[/tex]

Generally the p-value is mathematically represented as

     [tex]p-value = 2 * P(Z > 13.35)[/tex]

=>  [tex]p-value = 2 * 0.00[/tex]

=>  [tex]p-value = 0.00[/tex]

From the value obtained we see that  [tex]p-value < \alpha[/tex] hence we have that

       The decision rule is  

Reject the null hypothesis

        The conclusion is

There is no sufficient evidence to show that the claim that the vinyl gloves have a greater virus leak rate than latex gloves

Answer:

.

Step-by-step explanation:

Each box of pens are valued at $1.50, thus for 2 boxers it would be 1.50 x 2 = $3. Thus, 2 boxes of pens = $3. Each box of pencils cost $1. therefore 3 boxes of pencils valued at $1 each = to $3. Final equation $3 + $3 = $6 for the first purchase. Using the same numbers we valued the 2 boxes of pencils at $1 each = $1 pencil box + $1 pencil box = $2 for 2 boxes. Then 4 pen boxes valued at $1.50 each = to $1.50 x 4 = $6 Final equation $6pen + $2pencil = $8 final

Answer:

[tex]\frac{6}{4}[/tex]

Step-by-step explanation:

Use the following formula:

slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

([tex]x_1, y_1[/tex]) = (-4 , -4)

([tex]x_2 , y_2[/tex]) = (0 , 2)

Plug in the corresponding numbers to the corresponding variables:

(m) = [tex]\frac{2 - (-4)}{0 - (-4)} = \frac{2 + 4}{0 + 4} = \frac{6}{4}[/tex]

Your slope is [tex]\frac{6}{4}[/tex]. (Rise 6, Run 4)

~

Answer:

This means our slope is equal to [tex]\frac{6}{4}[/tex].

Step-by-step explanation:

Your ordered pairs are:

(-4, -4) and (0, 2)

To solve for the slope, we must use slope formula.

[tex]\frac{y2-y1}{x2-x1}[/tex]

Substitute:

[tex]\frac{2+4}{0+4}[/tex]

Solve:

[tex]\frac{6}{4}[/tex]

This means our slope is equal to [tex]\frac{6}{4}[/tex].

Answer:

90 Confidence Interval for the proportion = [ 0.216,0.334]

Step-by-step explanation:

The confidence interval for proportion formula =

p ± z × √p(1 - p)/n

Where p = x/n

x = 42

n = number of samples = 153

p = 42/153

p = 0.2745098039 ≈ 0.275

z = z score of 90% confidence interval = 1.645

Confidence interval =

0.275 ± 1.645 × √0.275 - ( 1 - 0.275)/153

= 0.275 ± 1.645 × √0.0013031046

= 0.275 ± 0.0593820985

Confidence Interval

= 0.275 - 0.0593820985

= 0.2156179015

≈ 0.216

= 0.275 + 0.0593820985

= 0.3343820985

≈ 0.334

90 Confidence Interval for the proportion = [ 0.216,0.334]

Answer:

x^33   y^0       x is to the 33   y is to the 0

Step-by-step explanation:

Answer:

^33

y^0

Step-by-step explanation:

First simplify x^8y/x^-39

Which then gets you

x^47 y^-26'/x^14 y^-5 y^-21

Then you simplify x^47/x^14

Which gets you

x^33 y^26/y^-5 v^-21

Then simplify y^-26/y^-5

Which gets you afterwards

x^33/y^21 y^-21

Then you just simplify the numbers that are left x^33/y^21 y^-21

Then you get

X^33

(and since x^33 equals y^0 then)

Y^0
