Complete Question
A sample of 1200 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature claimed that more than 50% do not fail in the first 1000 hours of their use. Is there sufficient evidence at the 0.10 level to support the company's claim
Answer:
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to conclude that the company's promotional literature claimed that more than 50% do not fail in the first 1000 hours of their use is correct
Step-by-step explanation:
From the question we told that
The sample size is n = 1200
The significance level is [tex]\alpha = 0.100[/tex]
The sample proportion is [tex]\^ p = 0.53[/tex]
The null hypothesis [tex]H_o : p = 0.50[/tex]
The alternative hypothesis is [tex]Ha : p > 0.50[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{\^ p - p }{ \sqrt{\frac{p(1 - p )}{n} } }[/tex]
=> [tex]z = \frac{ 0.53 - 0.5 }{ \sqrt{\frac{0.50 (1 - 0.50)}{1200} } }[/tex]
=> [tex]z = 2.078[/tex]
From the z table the area under the normal curve to the right corresponding to 2.078 is
[tex]P(Z > 2.078 ) = 0.018855[/tex]
So
[tex]p-value = 0.018855[/tex]
Generally the value obtained we see that [tex]p-value < \alpha[/tex] , Hence
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to conclude that the company's promotional literature claimed that more than 50% do not fail in the first 1000 hours of their use is correct
Mrs. Jackson earned a $500 bonus for signing a one-year contract to work as a nurse. Her salary is $22 per hour. If her first week’s check including the bonus is $1,204, how many hours did Mrs. Jackson work
Answer:
32 hours
Step-by-step explanation:
First setup an equation
500 + 22x = 1204 the x represents how many hours she worked an that is what we want to know. So to find out x you do this......
22x + 500 = 1204
1204-500= 704
704/22 = 32
So, X = 32 hours

Jane has 34 candles leftover from the last craft show and Brianna
has 2 candles. They are making more candles for the next show.
Jane makes 24 candles per hour and Brianna makes 32 candles per
hour. They are also going to use the candles left over from the last
show and want to have the same number of candles at their stalls for
this show. Let h represent the number of hours they need to work
for this.
Answer:
4 hours
Step-by-step explanation:
Given that the number of leftover candles for Jane = 34
and the number of leftover candles for Brianna = 2
Rate of candle making for Jane = 24 candles/ hour
Rate of candle making for Jane = 32 candles/ hour
As they work for h hours to make candles.
So, in h hours, the number of new candles made by Jane = 24h candles
For Jane, the total number of candles after h houres, including the leftover candles [tex]= 24h+34 \cdots(i)[/tex]
Similarly, in h hours, the number of new candles made by Brianna = 32h candles
For Brianna, the total number of candles after h houres, including the leftover candles [tex]= 32h+2 \cdots(ii).[/tex]
As they want to have the same number of candles at their stalls, so equating the numbers of candles from equations (i) and (ii), we have
[tex]24h+34=32h+2 \\\\\Rightarrow 32h-24h=34-2 \\\\\Rightarrow 8h=32\\\\[/tex]
[tex]\Rightarrow h=32/8=4[/tex] hours.
Hence, both need to work for 4 hours to have the same number of candles.

None of the other answers are correct
Answer:
Step-by-step explanation:
U right it’s not any of them and if u single I’m here
Answer:
B.
Step-by-step explanation:
AD, the entire segment, is composed of the three segments AB, BC, and CD. In other words:
[tex]AD=AB+BC+CD[/tex]
Since AB=CD, we can substitute:
[tex]AD=CD+BC+CD\\ AD=2CD+BC[/tex]
We know that CD is 9 and BC is 5x. AD is 53. So, substitute:
[tex]53=2(9)+5x[/tex]
Solve for x:
[tex]\begin{aligned} 53&=18+5x \\ 35&=5x \\ 7&=x \end{aligned}[/tex]
The value of x is 7.
Hence, our answer is B.

Jose bought 1.5 pounds of apples for $3.60.
How much would 34 of a pound of apples cost?
Enter your answer in the box.
Answer:
81.6
Step-by-step explanation:
If you do a table and find the unit rate by dividing 3.6/1.5. That gives you 2.4.
Now you multiply 2.4 (the price per pound) by 34 because that's how many pounds you need. You get 81.6
Answer:
$14.28
Step-by-step explanation:
1.5 / 3.60 = 0.42
0.42 * 34 = 14.28
you would divide the pounds by the money because you are trying to find 5e pounds per dollar. So then you get 0.42 the multiply that by 34 and you would get the answer of 34.
Find the slope of the line through points
(-8,2) and (1,3).
Write your answer in simplest form.
Answer:
The answer is
[tex] \huge \frac{1}{9} \\ [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
From the question we have
[tex]m = \frac{3 - 2}{1 - - 8} = \frac{1}{1 + 8} = \frac{1}{9} \\ [/tex]
We have the final answer as
[tex] \frac{1}{9} \\ [/tex]

brainiest plzzA man decides to buy a nice horse. He pays $60 for it, and he is very content with the strong animal. After a year, the value of the horse has increased to $70 and he decides to sell the horse. But already a few days later he regrets his decision to sell the beautiful horse, and he buys it again. Unfortunately he has to pay $80 to get it back, so he loses $10. After another year of owning the horse, he finally decides to sell the horse for $90. What is the overall profit the man makes?
Answer:
80!
Step-by-step explanation:
Goodluck!
Answer:
Horse Trade
Consider the trade-story as if it describes two separate trades, where:
In the first trade, the man buys something for $60 and sells it again for $70, so he makes a profit of $10.
In the second trade, the man buys something for $80 and sells it again for $90, so he makes again a profit of $10.
Conclusion: The man makes an overall profit of $10 + $10 = $20.
You can also look at the problem as follows: the total expenses are $60 + $80 = $140 and the total earnings are $70 + $90 = $160. The overall profit is therefore $160 - $140 = $20.

Answer:
HP=11
Step-by-step explanation:
Now that we have \blueE{HP}HPstart color #0c7f99, H, P, end color #0c7f99, we can find HDHDH, D.
\begin{aligned} HD&=\blueE{HP}+DP \\\\ &=\blueE{2}+9 \\\\ &=11 \end{aligned}
HD
=HP+DP
=2+9
=11
Using the AAA similarity theorem, the length of segment HD in the diagram given is: 11 units.
What is the AAA Similarity Theorem?If all corresponding angles of two triangles are congruent, then, they are similar triangles, based on the AAA similarity theorem.
ΔPOH ~ ΔPID by AAA similarity theorem.
Therefore, their corresponding sides would be proportional. Thus:
PH/PD = PO/PI
Substitute
PH/9 = 6/27
PH = (9 × 6)/27
PH = 2
HD = 2 + 9
HD = 11 units.

Step-by-step explanation:
i did it trust me
Using exponents, we know that expression (B) 125 × 125 is equivalent to the given expression 5⁶.
What are exponents?Exponentiation is a mathematical process that involves the base b and the exponent or power n. It is represented as bⁿ and is pronounced as "b to the n." The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself. For instance, the number 6 is multiplied by itself four times, yielding 6 6 6 6. You can write this as 6⁴. In this case, the exponent is 4 and the base is 6.So, 5⁶:
We know that 6 = 3 + 3:
Similarly,
5³⁺³We can say that:
5⁶ = 5³⁺³ = 5³ × 5³Now, simplify as follows:
5³ × 5³125 × 125Therefore, using exponents, we know that expression (B) 125 × 125 is equivalent to the given expression 5⁶.
