Step-by-step explanation:
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
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 :)

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. :(

15/5 = 3, 21/7 = 3 -- scale factor is 1/3 since he must divide by 3 to get the side lengths for the photo card
B.
Area = width*length, and scale factor is 5. Therefore, the new width is (15*5) and the new length is (21*5), so the new area is 15*5*21*5 = 15*21*5² = 15*21*25 = 315*25 = 7875 in²

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

Consider the data set. 2, 3, 5, 6, 7
(a) Find the range.
(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.)
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

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

Find the distance between the following points (1 , 6) and (13 , -3)
Answer:
15 units
Step-by-step explanation:
[tex]distance \: between \: 2 \: points \\ = \sqrt{(x1 - x2)^{2} + (y1 - y2)^{2} } [/tex]
Using the formula above, distance
[tex] = \sqrt{ {(13 - 1)}^{2} + {( - 3 - 6)}^{2} } \\ = \sqrt{ {12}^{2} + {( - 9)}^{2} } \\ = \sqrt{144 + 81} \\ = \sqrt{225} \\ = \textbf{15 units}[/tex]

43
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.

The largest Prime number less than 100 is ?
Answer: 97
Step-by-step explanation: The first 25 prime numbers (all the prime numbers less than 100) are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97 (sequence) just if you need all the primes
The largest prime number less than 100 is 97 by using the definition of prime number and examine the prime numbers that are smaller than 100.
To find the largest prime number less than 100, to examine the prime numbers that are smaller than 100.
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
Starting from 99 and moving downwards, check each number for divisibility by smaller numbers.
Any number that has divisors other than 1 and itself is not prime.
99 is not a prime number as it has more than one factors.
99 = 1, 3, 9, 11, 33, 99.
98 is not a prime number as it has more than one factors.
98 = 1, 2, 4, ........, 98.
97 is a prime number as it has more than one factors.
97 = 1, 97.
By doing this process, eventually reach 97, which is the largest prime number less than 100.

Given P(A) = 0.4 and P(B) = 0.6, do the following.(a) If A and B are independent events, compute P(A and B).(b) If P(A | B) = 0.5, compute P(A and B).
Answer:
Solution in photo
Step-by-step explanation:
Answer:
a) 0.24
b) 0.3
Step-by-step explanation:
Given the following probability
P(A) = 0.4 P(B) = 0.6
a) P(A and B) =P(A)P(B) {Independent)
P(A and B) = 0.4×0.6
P(A and B) = 0.24
b) Given P(A | B) = 0.5, this is a conditional probability
If P(A | B) = P(A and B)/P(B)
Since If P(A | B) = 0.5
0.5 = P(A and B)/P(B)
P(A and B) = 0.5(P(B)
P(A and B) = 0.5(0.6)
P(A and B) = 0.3
