Answer:
b. 14x+4y
Step-by-step explanation:
The perimeter is determined by two times the length plus two times the width.
We will use the formula P = 2L+2W:
P = 2L+2W
P = 2(5x-y)+2(2x+3y)
P = (10x-2y)+(4x+6y)
P = 14x+4y

x = 6
x = 3
x = 5
x = 4
Answers
Answer:
[tex](d)\ x = 4[/tex]
Step-by-step explanation:
Given
[tex]f(x) = -x^2 + 4x + 12[/tex]
[tex]g(x) = x + 8[/tex]
Required
Find x such that: [tex]f(x) = g(x)[/tex]
This gives:
[tex]-x^2 + 4x + 12 = x+8[/tex]
Collect like terms
[tex]-x^2 + 4x -x + 12 -8=0[/tex]
[tex]-x^2 + 3x +4 =0[/tex]

from top to bottom: 12, 17, 90
Step-by-step explanation:
the total for the first row is 45, and 2 of the numbers are 23 and 10. so, what you do is add 23 and 10 to get 33. Then you just subtract 33 from 45 to get 12.
Same with the other one. the total is 40 so you just subtract 23 from 40 to get 17.
The last one you add the numbers up. So 40+17+33 is 90.

Step-by-step explanation:
to help consumers assess the risks they are taking, the food and drug administration (FDA) publishes the amount of nicotine found in all commerical brands of ciagrettes. a new ciagrette has recently been marketed. the FDA tests on this ciagrette yielded mean nicotine content of 24.3 milligrams and standard deviation of 2.1 milligrams for a sample of 9 ciagrettes. construct a 99% confidence interval for the mean nicotine content of this brand of ciagrette.
Answers
Answer:
The 99% confidence interval for the mean nicotine content of this brand of cigarette is between 21.95 and 26.65 milligrams.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 9 - 1 = 8
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 8 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 3.3554
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 3.3554\frac{2.1}{\sqrt{9}} = 2.35[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 24.3 - 2.35 = 21.95 milligrams
The upper end of the interval is the sample mean added to M. So it is 24.3 + 2.35 = 26.65 milligrams
The 99% confidence interval for the mean nicotine content of this brand of cigarette is between 21.95 and 26.65 milligrams.

Which of the following pairs of triangles can be proven similar through SSS similarity?
Answers
Answer:

Step-by-step explanation:
The ΔDGF and ΔABC can be proven similar through SSS similarity. Therefore, option D is the correct answer.
We need to find which of the given pairs of triangles can be proven similar through SSS similarity.
What is SSS similarity?If all the three sides of a triangle are in proportion to the three sides of another triangle, then the two triangles are similar.
Now, form option D.
DF/AB=DG/AC=FG/BC
⇒8/2=10/2.5=11/2.75
⇒4=4=4
Thus, ΔDGF and ΔABC are similar.
Therefore, option D is the correct answer.
