Answer:

n+10

Step-by-step explanation:

This is applicable because if you plug in the numbers it will work for example. -

what sequence is 12 in, it is the second number so n=2

so add 10 to 2 which is 12

So as seen the answer is n+10

Answer:

No they would be $100 short.

Step-by-step explanation:

Answer: Solving for a missing exponent can be as simple as solving 4=2^x, or as complex as finding how much time must pass before an investment is doubled in value. (Note that the caret refers to exponentiation.) In the first example, the strategy is to rewrite the equation so both sides have the same base.

Answer:

x=35 y=18

Step-by-step explanation:

We have two triangles. These triangles are Similar as stated in the statement. Since they are similar, there side length will be in proportion.

To find x and y we need to set up a proportion of the corresponding sides of the triangles.

Let find the corresponding sides of both triangle.

JK corresponds with NM

KL corresponds with ML

JL corresponds with NL

To find side x we can use this proportion

JK/KL=NM/ML

Plug in the lengths

[tex] \frac{40}{kl} = \frac{16}{14} [/tex]

Cross multiply

[tex]560 = 16kl[/tex]

Divide by 16

[tex]kl = 35[/tex]

so x=35

Now to find y use this proportion

JL/JK=LN/NM

[tex] \frac{45}{40} = \frac{y}{16} [/tex]

Cross multiply

[tex]720 = 40y[/tex]

[tex]y = 18[/tex]

Answer:

X = 35

Y = 18

Step-by-step explanation:

The triangles are similar meaning that they are scaled up and down differently. ( and in this case rotated) Notice the shape of the triangles. The side measuring 40 in the larger triangle correlates to the side measuring 16 in the smaller triangle. We can use this to find the scale difference between the two triangles. 40/16 = 2.5. The larger triangle is scaled up 2.5 times the smaller triangle. X correlates to the side measuring 14. Scale 14 up 2.5 times. 14* 2.5 = 35, so x= 35.

Y correlates to the side measuring 45. Scale 45 down 2.5 times. 45/2.5 = 18. Y = 18

Answer:

Step-by-step explanation:

because the outer line is one line and the triangle in other line

Answer:

3

Step-by-step explanation:

There is a line of symmetry from each vertex of the triangle through the square opposite it. I can't draw it out here but there's one going straight down the middle, another going from the triangles leftmost point through the right hand square and another from the triangles rightmost point through the left hand square.

The solution set for the quadratic equation (2x - 7)² = 25 is 6 and 1.

A quadratic equation is an algebraic expression in the form of variables and constants.

A quadratic equation has two roots as its degree is two.

The solution set for a quadratic equation is the roots of the quadratic equation.

Given, (2x - 7)² = 25.

2x - 7 = ± 5.

2x = ± 5 + 7.

x = (± 5 + 7)/2.

x = 12/2 Or 2/2.

x = 6 or 1.

Those are the side lengths not the angles so I'm not sure, also are you sure that's right? I believe there has to be a hypotenuse and the hypotenuse is the sum of the two shorter sides added together.

Step-by-step explanation:

Answer:

Accept the null hypothesis

Step-by-step explanation:

Two years ago, the average number of customers in your all of your company's stores per week was 3173 customers. Assume that you are doing a current study to test the claim that the mean weekly number of customers is different than it was two years ago.

The null hypothesis is:

[tex]H_{0} = 3173[/tex]

The alternate hypothesis is:

[tex]H_{A} \neq 3173[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

Due to our test, we have that [tex]\mu = 3173[/tex]

Assume a population standard deviation of 1,550 customers.

This means that [tex]\sigma = 1550[/tex]

Suppose you look at a random sample of 73 stores and find an average weekly customer total of 3,391.

This means that [tex]n = 73, X = 3391[/tex]

Test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{3391 - 3173}{\frac{1550}{\sqrt{73}}}[/tex]

[tex]z = 1.24[/tex]

p-value:

Since we are testing if the mean is different of a value, and the z-score is positive, the pvalue is 2 multiplied by 1 subtracted by the pvalue of z = 1.24.

z = 1.24 has a pvalue of 0.9251

2*(1 - 0.9251) = 2*0.0749 = 0.1498

0.1498 > 0.1, which means that we accept the null hypothesis, that is, that the mean weekly number of customers is equal to what it was two years ago at the 0.1 level of significance.

Answer:

y=-12x+20

Step-by-step explanation:

-4=-12(2) +b

-4=24+b

(add 24 both sides)

20=b

slope: -12

y intercept: (0,20)

Answer:

y + 4 = -12(x - 2)

Step-by-step explanation:

Use the point-slope formula for the equation of a straight line:

y - k = m(x - h)

Here m = -12, h = 2 and k = -4, and so we have:

y + 4 = -12(x - 2)

Answer:

8,10,12

Step-by-step explanation:

Answer:

integer 1 = 8

integer 2 = x+2 = 8+2 = 10

integer 3 = x+4 = 8+4 = 12

Step-by-step explanation:

integer 1 = x , smallest

integer 2 = y , x+12

integer 3 = z , largest, x+4

three times the smallest is twice the largest.

3 (x) = 2 (x+4)

solve for x:

3x = 2x + 8

3x-2x = 8

x = 8

Replacing:

integer 1 = 8

integer 2 = x+2 = 8+2 = 10

integer 3 = x+4 = 8+4 = 12

Answer:

Every month, he will spend $30 of his $1000.

Step-by-step explanation:

The first thing I did was found out 3% of 1000. To do this, you need to move the decimal point in 3% over twice. Like this:

3 → .03

Then, multiply 1000 by .03.

1000 * .03 = 30

So, this means that he will spend $30 of his money each month.
