What is the slope of a line that is perpendicular to the line that passes through the points (4, 7) and (9, 3)?

Answers

Answer 1

Answer:

5/4

Step-by-step explanation:

The original line is

7 - 3 / 4 - 9

4/-5, so the slope is -4/5

Perpendicular means the opposite sign and reciprocal.

5/4

You buy a sweater that is on sale for 20% off of the original price. The sweater cost $28. What was the original price?

Answers

Answer:

The original price was $50.

Step-by-step explanation:

Your sweater now cost $28 after 20% off.

To find this we need to start with the price you paid ($28). We then use this cost to find the pre-coupon price. Since the coupon affords a 20% discount, that means you pay for 80%. To solve this, simply divide the price you paid by the percentage you paid.

$28/.80 = $35.

Now that we have the pre-coupon price ($35), we can use that to find the original price. Again, we'd want to divide that by the percentage you paid for, which is 70%.

$35/.70 = $50

Step-by-step explanation:

Think of doing 35*4 but dividing the result by 100, or 2 decimal places to the left:

Answers

Answer:

[tex]y \: = \: \frac{2}{13} x \: + \: \frac{9}{13} [/tex]

Step-by-step explanation:

we need to write it in the form y = mx + c where m is the slope(gradient) and y is the y intercept

1) add 9 to both sides

2x = 13y - 9

2x + 9 = 13y

2)divide 13 on both sides

2x + 9 = 13y

2/13x + 9/13 = y

final equation is

Estimate the line of best fit using two points on the line.

Answers

Answer:   i think it's b

Answer:

C.

Step-by-step explanation:

A and D are immediately wrong since the line is increasing.

Using the formula of rise over run, we can find the slope. We then use 40 as the rise and 5 as the run

40/5 is 8.

We can now put 8 as the slope in the y=mx+b equation. We can see the line intersect at 20 at the y-axis, which makes 20 the y-intercept. We can now insert that into the b part of the equation. This leaves us with y=8x+20.

Answers

Using the z-distribution, it is found that the value of the test statistic is z = 10.33.

At the null hypothesis, it is tested if the proportion is of [tex]\frac{3}{4} = 0.75[/tex], hence:

[tex]H_0: p = 0.75[/tex]

At the alternative hypothesis, it is tested if the proportion is different, that is:

[tex]H_1: p \neq 0.75[/tex]

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

[tex]\overline{p}[/tex] is the sample proportion. p is the proportion tested at the null hypothesis. n is the sample size.

For this problem, the parameters are: [tex]p = 0.75, \overline{p} = 0.89, n = 1201[/tex]

Hence:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.89 - 0.75}{\sqrt{\frac{0.75(0.25)}{1021}}}[/tex]

true or false 3 x 10^4 is 5 times as much as 6 x 10^3

Answers

Answer:

True

Step-by-step explanation:

1. To find if this statement is true or false, we first have to evaluate the value of these numbers.

[tex]3 * 10^4 = 3 * 10 * 10 * 10 * 10 = 30 * 10 * 10 * 10 = 300 * 10 * 10 = 3000 * 10 = 30000[/tex] [tex]6 * 10^3 = 6 * 10 * 10 * 10 = 60 * 10 * 10 = 600 * 10 = 6000[/tex]

2. Next, we divide 30,000 by 6,000. If our quotient is 5, then this is true.

[tex]30,000/6,000[/tex] [tex]5[/tex]

Therefore, this is true.

Find the value of x and the indicated angles.

Answers

Answer:

x = 19

Indicated angles: 113°

Step-by-step explanation:

We can tell that 6x - 1 is equal to 2x + 75 because they are vertically opposite angles. Now, let's solve.

=> 6x - 1 = 2x + 75=> 6x - 2x = 1 + 75=> 4x = 76=> x = 19

Since we have found the required variable, we can now solve the indicated variables.

Given angles:

6(19) - 12(19) + 75

Let's solve 6(19) - 1 first.

6(19) - 1=> 114 - 1=> 113

Therefore, 6(19) - 1 measures about 108°. Now, let's solve 2(19) + 75

2(19) + 75=> 38 + 75=> 113

We can clearly see that both angles are equal (113 = 113) Because of vertically opposite angles.

Conclusion:

Therefore, the required variable is 'x = 19' and when we substitute the variable in both angles, we find that both angles show 113°.

The remainder when the polynomial is divided by x + 1 is 2

Given the function P(x)=3x^4 −2x^3 +2x^2 −1, to get the rmainder if the polynomial is divided by x + 1, we will substitute x = - 1 into the function to have:

P(-1) = 3(-1)^4 −2(-1)^3 +2(-1)^2 −1

P(-1) = 3(1) - 2 + 2(1) - 1

P(-1) = 1 + 1

P(-1) = 2

Hence the remainder when the polynomial is divided by x + 1 is 2
