I don't know how to solve this at all. please help
Answers
Answer:
5. 97
Step-by-step explanation:
Well, we know that all we have to do is add QRP and PRS. so 71+25 is 96 (but put 97). For the other one you can do 2x-5=x+1. Then you just solve for x. For the y value you do the same thing, 3y=5y+3. So, x=2 but y=1.5 but its not an answer choice... I know the second one didn't help you, sorry. :(
Salena has twice as many DVDs as Jolene,and Jolene has one third as many as Brodie.What fraction of the total DVDs has Salena?
Answers
Answer: 1/3
Step-by-step explanation:
Assume Jolene's DVDs are x.
Selena has twice as many DVDs as Jolene so Selena has 2x DVDs.
Jolene has 1/3 as many DVDs as Brodie which means that Brodie has 3 times as many DVDs as Jolene which is 3x.
Total DVDs = x + 2x + 3x
= 6x
Salena has 2x.
Fraction = 2x/6x
= 1/3

Answers
Answer:
X is 137.
Step-by-step explanation:
Because they are parallel, we can see that because of alternate exterior angles, the angle next to X is 43, and we subtract that from 180 which gives us x, or 137.

Derek heard someone say that high school quarterbacks in Texas are almost all more than 6
feet tall. Derek wonders about the validity of that statement. He decides to collect some
data to estimate the mean height of high school quarterbacks playing in the state of Texas.
Since it is impractical to try to measure every quarterback’s height personally, Derek decides
to randomly collect a sample of the heights of 15 Texas high school quarterbacks.
The quarterback heights, to the nearest inch, Derek collected are:
69”, 72”, 75”, 68”, 70”, 67”, 75”, 73”, 69”, 71”, 74”, 75”, 68”, 70”, 73”
Using this data, estimate the population mean of the heights of high school quarterbacks in
Texas to the nearest inch

Answer:
179/495
Step-by-step explanation:
x = 0.3616161.......... ---------------(I)
Multiply by 1000
1000x = 361.616161......
Multiply (I) by 10
10x = 3.616161........
1000x = 361.6161......
10x = 3.6161........ {Now subtract}
990x= 358
x = 358/990
x = 179/495

(b) Use the defining formula to compute the sample standard deviation s. (Round your answer to two decimal places.)
(c) Use the defining formula to compute the population standard deviation σ. (Round your answer to two decimal places.)
Answers
Answer:
5 ; 2.07 ; 1.85
Step-by-step explanation:
Given the data:
2, 3, 5, 6, 7
The range : ( highest - lowest)
The range = (7 - 2) = 5
Sample standard deviation :
sqrt[Σ(x - m)²/ (n - 1)]
The mean (m) = Σx / n
n = sample size = 5
Σx / n ;
(2+3+5+6+7) / 5
= 23 / 5
= 4.6
[(2-4.6)^2 + (3-4.6)^2 +(5-4.6)^2 + (6-4.6)^2+ (7-4.6)^2] / (5 - 1)
= 17.2 / 4
= 4.3
Sqrt(4.3) = 2.07
Population standard deviation :
sqrt[Σ(x - m)²/ n]
The mean = m = 4.6
n = sample size = 5
[(2-4.6)^2 + (3-4.6)^2 +(5-4.6)^2 + (6-4.6)^2+ (7-4.6)^2] / 5
= sqrt(17.2 / 5)
= sqrt(3.44)
= 1.8547 = 1.85

Write the slope-intercept form of an equation of the line that passes through (a, - 4) is parallel to the graph of 4x - y = 2 y = - 1/4 * x + 4 y = 1/3 * x - 4 y = 4x - 4 D y = - 4 - 4
Answers
The first questions answer:
Given (0, -4), 4x - y = 7. I converted the equation into slope intercept form and I got: y = 4x - 7. Once I had gotten that I put (0, -4) and the equation into Point-Slope Form and solved it: y - (-4) = 4(x + 0), y + 4 = 4x, y = 4x - 4 is the slope intercept form of your equation and point :)
