Solve the following inequality for x.
x - 9 ≤ 2(9 - x)
A. x ≤ 9
B. x ≥ 11
C. x < -7
D. x < 10
Step-by-step explanation:
x-9≤2(9-x)
distribute
x-9≤18-2x
add 2x on both sides
3x-9≤18
add 9 on both sides
3x≤27
divide by 3
x≤9
Answer:
here is the answer verified by edmentum if anyone needs it
Step-by-step explanation:
In manufacturing processes, it is of interest to know with confidence the proportion of defective parts. Suppose that we want to be reasonably certain that less than 4% of a company's widgets are defective. To test this, we obtain a random sample of 250 widgets from a large batch. Each of the 250 widgets is tested for defects, and 6 are determined to be defective, based upon the manufacturer's standards. Using α = 0.01, is this evidence that less than 4% of the company's widgets are defective? State the hypotheses, list and check the conditions, calculate the test statistic, find the p-value, and make a conclusion in a complete sentence related to the scenario.
Answer:
Less than 4% of a company's widgets are defective.
Step-by-step explanation:
In this case we want to be reasonably certain that less than 4% of a company's widgets are defective.
The significance level of the test is, α = 0.01.
The hypothesis can be defined as follows:
H₀: At least 4% of a company's widgets are defective, i.e. p ≥ 0.04.
Hₐ: Less than 4% of a company's widgets are defective, i.e. p < 0.04.
The information provided is:
n = 250
x = 6
The sample proportion is, [tex]\hat p=\frac{x}{n}=\frac{6}{250}=0.024[/tex]
Compute the test statistic value as follows:
[tex]z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}\\\\=\frac{0.024-0.04}{\sqrt{\frac{0.04(1-0.04)}{250}}}\\\\=-1.29[/tex]
The test statistic value is -1.29.
The decision rule is:
The null hypothesis will be rejected if the p-value of the test is less than the significance level.
Compute the p-value as follows:
[tex]p-value=P(Z<-1.29)=0.0985[/tex]
So,
p-value = 0.0985 > α = 0.01.
The null hypothesis will not be rejected at 1% significance level.
Thus, there is not enough evidence to support the claim.
Conclusion:
Less than 4% of a company's widgets are defective.

Eli wanted to order candy online. Company A is offering 2 1/2 pounds of chocolate for $32.00. How much is Company A charging per pound of chocolate?
A. $12.80 per pound of chocolate
B. $16.25 per pound of chocolate
C. $0.07 per pound of chocolate
D. $15.75 per pound of chocolate
Answer:
A) $12.80 per pound of chocolate
Step-by-step explanation:
As, 2 1/2 pounds = 5/2 = 2.5
So for 2.5 pounds = $32
For 1 pound = 32/2.5 = 12.80
So, = 12.80

All basketballs at a sporting goods store were marked down 25% during the first week of a sale. During the third week, all remaining basketballs were marked down an additional 30%. If a basketball was originally $22, how much does it cost during the third week?
Answer:
selling price= $9.9
Step-by-step explanation:
Giving the following information:
During the third week, all remaining basketballs were marked down an additional 30%.
Original price= $22
To calculate the selling price in the third week, we need to use the following formula:
selling price= original price*(1 - markdown)
selling price= 22*(0.45)
selling price= $9.9
A store sells 12-packs of ballpoint pens for $1.09 each and composition books for $2.79 each. Cindy buys m packs of ballpoint pens and n composition books. The store offers a 5% discount for every 50th customer who makes a purchase. If Cindy gets the 5% discount, which expression will represent Cindy’s bill?
A.
0.05 − 1.09m + 2.79n
B.
1.05 + 1.09m + 2.79n
C.
1.05(1.09m + 2.79n)
D.
0.95(1.09m + 2.79n)
Answer:
D
Step-by-step explanation:
100% is 1-
5% is 0.05
1-0.05 = 0.95

Can someone help me with this?
Answer:
8x + 5y > 400
(50, 0) for x-intercept
(0,80) for y-intercept
Step-by-step explanation:
We will let x be the # of tshirts and y be the # of hats.
The inequality is 8x + 5y > 400; the coefficient 8 comes from $8 per tshirt and 5 from $5 per hats.
For x intercept, you let y = 0;
8x + 5(0) = 400;
8x = 400; divide by 8
x = 50 or (50, 0)
For y intercept, you let x = 0;
8(0) + 5y = 400;
5y = 400; divide by 5
y = 80 or (0,80)

If DB = 36 and AC = 3x - 3, what is the value of x?
Answer:
A.) 13
Step-by-step explanation:
Since DB =36, and AC is the same line, then AC = 36. The new equation is 36 = 3x - 3. Do inverse operation. Add 3 to both sides of the equation: 36+3=39 & -3+3=0. New equation is 39=3x. Finally divide. 39/3= 13.

Answer:
\frac{30}{104}
Step-by-step explanation:
9 is the number of boys who play football AND wrestle. 18 is the mumber of footballers, and 12 is the number of wrestlers.
18 + 12, or 30, is the number of boys who EITHER play football or wrestle.
The total number of boys playing sports is 104, so 30 out of 104 boys either play football or wrestle.
You can write this in fraction form as [tex]\frac{30}{104}[/tex].
Answer:
39/143 (B)
Step-by-step explanation:
All the boys who play football, wrestle, or both equals 18 + 12 + 9 = 39
All of the boys are the boys who play football, wretle, or both (39) + the number of outlier boys, (104) = 143 boys in total.
There is a probability of 39/143 that a boy will wrestle or football.
Joshua was offered a job that paid a salary of $77,500 in its first year. The salary was set to increase by 2% per year every year.
If Joshua worked at the job for 5 years, what was the total amount of money earned over the 5 years, to the nearest whole
number?
Answer:
if you want it as dollars and cents it is $77.50 but in nearest whole number it would be 78 dollars
Step-by-step explanation:
step 1: multiply the 2 by 5 and you get 10%
step two: you put 10 over 100 and multiply 77,500
10/100 x 77,500/1= $77.50
but when you roung it off you get 78 dollars
