Alice has 15 times as many crayons as Bryan. Write an equation to find the total number of crayons that Alice has.
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
Use the sample data and confidence level given below to complete parts (a) through (d). A drug is used to help prevent blood clots in certain patients. In clinical trials, among 4547 patients treated with the drug, 114 developed the adverse reaction of nausea. Construct a 99% confidence interval for the proportion of adverse reactions. a) Find the best point estimate of the population proportion p.
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).

The Johnson family pays 1,783 per month for rent. If the cost of their rent remains the same, how much will they pay for rent over 15 years?
Answer:
1 year= 12 months
1 months rent=1783
1783x12=21396
15 years = 180 months
the equation would be
1783x180=320940

What is the slope represented in the table ?
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.

Which of the following is true? A) −16=−16 B) −29>24 C) −47<−43 D) −70<−77
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.

Can anyone help me with this question? I can’t find the answer for the ? Box
The question(s) are :
-4 - ? = -7
? - (-3) = 5
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 = ?

Find x and the size of each angle
in this triangle.
6x + 20
4.2
80 - 2.0
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
How can the value of x be gotten?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]

Your pay rate is $20 per hour and you have a weekly pay period. You have worked overtime and accumulated 50 hours for the week. You get paid time and a half for overtime hours. Calculate your gross pay. *
Answer:
$1200 gross pay
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
X = 1200
