Answer:
10
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
The answer is 10 because:
1) Absolute value makes all negative or positive numbers positive (unless there is a negative sign outside the absolute value sign).
2) Therefore, the absolute value of 10 is positive 10.

REE A manufacturer of window frames knows from past experience that 10 per cent of the production will have some type of minor defect that will require adjustment. Suppose 20 window frames are selected at random: a. How many window frames would you expect to have minor defects? (2 points) b. Calculate the standard deviation for the number of window frames to have minor defects in this random sample of 20 window frames. (2 points) c. Calculate the probability that exactly 2 window frames will need minor . adjustment. (2 points) d. What is the probability that more than 3 window frames will need minor adjustments? (7 points)
Answer:
10% to decimal is equal to 0.1.
Therefore 20 x 0.1 = 2
Step-by-step explanation:
Each window is independently probable for having minor defects. The expected number of window frames having minor defects = 2.
Other figures are:
Standard deviation for the number of windows frames to have minor defects in this random sample of 20 window frames = 1.34 approx.P(Exactly 2 windows will need minor adjustment) = 0.285 approx.P(More than 3 windows will need minor adjustment) = 0.1329 approx.How to find that a given condition can be modeled by binomial distribution?Binomial distributions consists of n independent Bernoulli trials.
Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))
Suppose we have random variable X pertaining binomial distribution with parameters n and p, then it is written as
[tex]X \sim B(n,p)[/tex]
The probability that out of n trials, there'd be x successes is given by
[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]
The expected value and variance of X are:
[tex]E(X) = np[/tex][tex]Var(X) = np(1-p)[/tex]For the considered case, we can assume that each window is independent of each other for having defects or being perfect.
Each window can be having defects (call it success) or no defects(call it failure).
Then, we can take:
X = number of windows out of 20 windows being perfect (no defect).
Then we get:
Success = window having defectn = 20p = 10% = 0.10 (as given in the problem)[tex]X \sim B(n=20,p=0.1)[/tex]Evaluating each sub parts one by one:
Case a: How many window frames would you expect to have minor defects?Expect number of defective windows = E(X) = np = 20 × 0.1 = 2
Case b: Calculate the standard deviation for the number of window frames to have minor defects in this random sample of 20 window frames.Standard deviation is the positive root of variance.
Standard deviation of number of windows (out of 20 windows of sample) having defects = [tex]\sqrt{Var(X)} = \sqrt{np(1-p)} = \sqrt{2(0.9)} \approx 1.34[/tex]
Case c: Calculate the probability that exactly 2 window frames will need minor adjustment.P(X = 2) = [tex]^{20}C_2(0.1)^2(0.9)^{18} \approx 0.285[/tex]
Case d: What is the probability that more than 3 window frames will need minor adjustments?P(X > 3) = 1 - P(X ≤ 3)
[tex]P(X > 3) = 1 -[ P(X = 0) + P(X = 1) +P(X= 2)+ P(X = 3)]\\\\P(X > 3) = 1- [^{20}C_0(0.1)^0(0.9)^{20} +^{20}C_1(0.1)^1(0.9)^{19} +\\\: \:\: ^{20}C_2(0.1)^2(0.9)^{18} +^{20}C_3(0.1)^3(0.9)^{17} ]\\\\P(X > 3) \approx 1-[ 0.1216 + 0.2702 + 0.2852 + 0.1901]=1-0.8671=0.1329 \\\\P(X > 3) \approx 0.1329[/tex]
Thus, the needed figures are:
Expected number of window frames having minor defects = 2Standard deviation for the number of windows frames to have minor defects in this random sample of 20 window frames = 1.34 approx.P(Exactly 2 windows will need minor adjustment) = 0.285 approx.P(More than 3 windows will need minor adjustment) = 0.1329 approx.Learn more about binomial distribution here:

Ms.Barton ate an impressive number of slices, but Mr.weaver ate eight more slices than Ms.Barton did. Mr.Fitzgerald ate fifteen Fewer slices than twice as many as Ms.Barton did. Mr.Lloyd’s total was more thirty than half of Ms.Barton’s
If the teachers ate a total of 176 slices of pie, what was the finishing order of the contest and how many slices did the winner eat?
Let:
Ms. Barton = b
Mr. Weaver = b + 8
Mr. Fitzgerald = 2b - 15
Mr. Lloyd = 1/2b + 30
Find b:
176 = b + b + 8 + 2b - 15 + 1/2b + 30
176 = 9/2b + 23
153 = 9/2b
b=34
Plug in 9 to b:
Ms. Barton = 34 slices (4th place)
Mr. Weaver = 34 + 8 = 42 slices (3rd place)
Mr. Fitzgerald = 2(34) - 15 = 53 slices (1st place)
Mr. Lloyd = 1/2(34) + 30 = 47 slices (2nd place)

What is the solution of the system of equations below?
y = x + 2
y = 3x
Answer:
x=1,y=3
Step-by-step explanation:
in each linear equation, identify the slope (m) and the y-intercept (b)
Hey there!
Let's find the slope & y-intercept of each equation.
The first one is y=4x-5.
Please remember that
In slope-intercept equations. the slope is the coefficient of x (the number before x)Also, the y-intercept is the number/variable that's added/subtracted to/from the slope.In other words, in slope-intercept form (y=mx+b), m is always the slope and b is the y-intercept.
Therefore, the slope of the first linear equation is 4, and the y-intercept is -5.
or
m=4, b=-5 (option A)
Same with the other equation:
m=-1, b=2/3 (option C is the right option)
Hope everything is clear.

Answer:
CD = EC ⇒ proved down
Step-by-step explanation:
If a point lies on a segment, then it divides the segment into two parts, the sum of their length equals the length of the segment
Example:
If point Z lies on the segment XY, then Z divides XY into segments XZ and ZY, where XY = XZ + ZY
Let us use this fact to solve the question
∵ BD and EF intersected at point C
∴ C divides BD into two segments BC and CD
∴ C divides EF into two segments EC and CF
→ By using the fact above
∴ BD = BC + CD
∴ EF = EC + CF
∵ BD = EF ⇒ given
→ Equate their right sides
∴ BC + CD = EC + CF
∵ BC = CF ⇒ given
→ That means their adding segments are equal
∴ CD = EC ⇒ proved

Suppose you borrow $1,000 for 5 years at an add-on interest rate of 6%, what is the approximate APR? Round your answer to one decimal place. Include the correct unit.
The approximate APR generated when you borrow $1,000 for 5 years at an add-on interest rate of 6%, = $300
Calculation of Annual percentage rateAnnual percentage rate is defined as the yearly interest generated by a sum that's charged to borrowers.
The formula for APR = p×t×r/100
The principal amount deposited (p)= $1000
Time (t) = 5 years
At the rate (r) = 6%
Therefore APR=
[tex] \frac{p \times t \times r}{100} [/tex]
[tex] \frac{1000 \times 5 \times 6}{100} [/tex]
[tex] \frac{30000}{100} [/tex]
APR = $300
Therefore, the approximate APR = $300

Answer:
75 degrees and 105 degrees.
Step-by-step explanation:
So this is a transversal. We can use a couple different methods to solve this. We can use many different theorems to solve this problem. So we know that m<2=m<4 because of vertical angles, we also know that m<4=m<6 because of alternate interior angles. We also know that m<6=m<8 because of vertical angles. So we know that m<2=m<4=m<6=<8. In a transversal, there are only two different measurements. And those two different measurements add up to 180 degrees. So since once of the measurements is 75, that means the other measurement has to be 105 degrees. Also, we see that m<4 and m<5 are same side interior angles and according to that theorem, they have to equal up to 180 degrees.
