Answer:
Q1: 0.88015 ~ 88.015%, are
Q2: 0.88176 ~ 88.176%, are not
Step-by-step explanation:
Okay so a simple way to do these probability ones is to add an extra space around each side
A B C D
ACCURATE 310 262 246 144 ___
NOT ACCURATE 31 51 37 12 ___
___ ___ ___ ___ ___
Now in these spaces add all the the rows and columns accordingly
A B C D
ACCURATE 310 262 246 144 _962_
NOT ACCURATE 31 51 37 12 _131_
_341_ _343_ _283_ _156_ _1093_
Now the number in the place where the additional rows meet is your total number of orders, so this is what you would use for your probability.
So we are looking for ACCURATE / ALL which is 962
Now do 962 divided by 1093 and your probability comes out to 0.88015, so as a percentage, would be 88.015%
With replacement, all variables become independent, however without replacing that changes the probability.
When the 2 orders are selected, the final number of probability changes - so it would take down the total each time, the find the mean or average of the probability for your answer.
So since there is no replacement for ACCURATE / ALL which is 962, the division instead would be by 1091, since we are taking 2 orders out and not putting them back, it brings down the total number by 2, which would make the probability come out to 0.88176, or 88.176%

Answer:
x = 12.633, -0.633
Step-by-step explanation:
x^2 -12x + 36 = 44
the underlined part is (x - 6) ^2
(x - 6)^2 = 44
(x - 6) = ± [tex]\sqrt{44}[/tex] (both positive and negative)
(x - 6 ) = + 6.6332495807108
x = 12.6332495807108 = 12.633
(x - 6 ) = - 6.6332495807108
x = - 6.6332495807108 + 6
= -0.6332495807108 = -0.633

five more than one-third of a number is -2. Find the number
Answers
Answer:
x = -21
Step-by-step explanation:
Words To Algebra:Words : Five more than one-third of a number = -2
Algebraic Equation: 5 + (1/3)x = -2
Isolate x:5 + (1/3)x = -2 [tex]\longmapsto\\[/tex] Subtract 5 from both sides
5 + (1/3)x - 5 = -2 - 5
(1/3)x = -7 [tex]\longmapsto\\[/tex] Multiply All sides by 3
(1/3)x * 3 = -7 * 3
x = -21
Check:5 + (1/3)-21 = -2
5 + -7 = -2
-2 = -2

Which equation represents a line which is parallel to the line y = -5/8x + 6?
A) 8x + 5y = 10
B) 8x - 5y = 15
C) 8y - 5x = -24
D) 5x + 8y = 32
Answers
Step-by-step explanation:
y = -5x/8 + 6
8y = 8 × (-5x/8 + 6)
8y = -5x + 42
5x + 8y = 42
5x + 8y = K, k element real
Option → D
The equation for parallel line is 5x + 8y = 32.
The correct option is (D).
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Equation: y = -5/8x + 6
Now, the parallel line to above equation must have the slope same as the given equation i.e., -5/8.
Then, writing the equation in slope intercept form
A) 8x + 5y = 10
5y= 10 - 8x
y= 10/5 - 8x/5
y= -8/5x + 2
B) 8x - 5y = 15
-5y= 15 - 8x
y= 8/5 x + 3
C) 8y - 5x = -24
8y= -24 + 5x
y= -24/8 +5/8x
y= +5/8x - 3
D) 5x + 8y = 32
8y= 32 -5x
y= -5/8x + 4
Hence, the equation for parallel line is 5x + 8y = 32.

w than Peyton.
Answers
Answer:
Aaron earns $1.3 per hour more than Peyton
Step-by-step explanation:
Aaron's income is represented by y=29.8x
x represents the number of hours worked
Given that Peyton earns 627 in 22 hours. We want to know how much Aaron earn in 22 hours. We then substitute 22 into the equation as x.
y = 29.8(22)
y = $655.6 in 22 hours
This means that Aaron earns $655.6 in 22 hours.
Therefore, Aaron earns 28.6 dollars more in 22 hours.
We want to know the rate per hour so we divide 28.6 by 22.
rate per hour = 28.6/22
rate per hour = $1.3
Therefore, Aaron earns $1.3 per hour more than Peyton.

The length of a rectangle is 4 units more than triple its width. If the perimeter is 64,
what is the length of the rectangle?
Answers
Answer: Length = 25, width = 7
Step-by-step explanation:
Let width be w, and length be 3w + 4.
Perimeter of a rectangle = 2l + 2w
64 = 2(3w + 4) + 2w
64 = 6w + 8 + 2w
64 = 8w + 8 [subtract 8 from both side]
56 = 8w [Divide 8 from both side]
w = 7
Plug w in l, where l = 3w + 4 = 21 + 4 = 25
