find the value of x and y in the parallelogram

Answer:

A and C are true.

Step-by-step explanation:

-16 = -16 that's just a given, they are the same number. And -47 is less than -43, since -43 would be a higher number considering it's in the negatives.

Answer:

a = 15b

Step-by-step explanation:

It's given in the question that Alice has 15 times as many crayons as Bryan.

Let the number of crayons with Bryan = b

And the number of crayons with Alice = a

Therefore, equation representing the number of crayons with Alice will be,

a = 15b

Answer:

553

Step-by-step explanation:

All we need to do is get the ? by itself in both equations.

-4 - ? = - 7

-? = -7 + 4

-? = -3

? = 3

? - ( -3) = 5

? + 3 = 5

? = 5 - 3

? = 2

Answer:

First ?: 3

Second ?: 2

Step-by-step explanation:

Do the inverse operation of what is shown to get the answer.

First ?:

-4 - ? = -7

-7 + 4 = -?

-3 = -?

3 = ?

Second ?:

? + 3 = 5 (Two negatives in a row make a positive.)

5 - 3 = ?

2 = ?

Answer:

6x + 20 + 4x + 80 - 2x=180

6x + 4x - 2x= 180 - 80 - 20

8x = 80

x = 10

The value of x in the triangle is 10, the value of each angle are; 80, 40 , 60 respectively

The total angle can be added as

note that the total angle in the triangle is 180

[tex]6x + 20 + 4x + 80 - 2x=180[/tex]

[tex]6x + 4x - 2x= 180 - 80 - 20[/tex]

[tex]8x = 80x = 10[/tex]

Then we can know the angles as ;

[tex]6x + 20=(6*10) +20 =80\\4x = 4*10 = 40\\80 - 2x = 80 - (2*10) = 60[/tex]

Answer:

The best point estimate of the population proportion p is 0.0251.

The 99​% confidence interval for the proportion of adverse reactions is (0.0191, 0.0311).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

In clinical​ trials, among 4547 patients treated with the​ drug, 114 developed the adverse reaction of nausea.

This means that [tex]n = 4547, \pi = \frac{114}{4547} = 0.0251[/tex]

The best point estimate of the population proportion p is 0.0251.

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.0251 - 2.575\sqrt{\frac{0.0251*0.9749}{4547}} = 0.0191[/tex]

The upper limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.0251 + 2.575\sqrt{\frac{0.0251*0.9749}{4547}} = 0.0311[/tex]

The 99​% confidence interval for the proportion of adverse reactions is (0.0191, 0.0311).

Answer:

slope:2

Step-by-step explanation:

Slope is rise/run, or change in y/change in x.

With that being said, we only need two points to solve this.

Let's take the points (0,7) and (1,9)

The formula for finding the slope from two points is m=(y2-y1)/(x2-x1).

M is the slope.

y2 would be the y-value of the second point,9. y1 would be the y-value of the first point, 7.

x2 would be the x-value of the second point, 1. x1 would be the x-value of the first point, 0.

Plugging those values in to the formula, we get m=(9-7)/(1-0)

Simplifying, we get m=2/1, which is m=2.

Step-by-step explanation:

if you worked 40 hours normally and had 10 hours over time, that equation for the gross pay would be X = 20(40) + 30(10)

X = 20(40) + 30(10)

X = 800 + 300
