Carolyn earns $34 for an 8-hour day. Yesterday she took 3 hours off without pay. How much money did she lose?
Answer:
12.75$ lost
Step-by-step explanation:
34/8=4.25 × 3=12.75$
She lost $12.75 for taking 3 hours off without pay
Step-by-step explanation:
If she makes $34 every 8 hours, that goes down to $4.25 per hour. If she took 3 hours off without pay, we simply would multiply her hourly rate of $4.25 by the amount of hours she took off without pay (3) and we'd get our answer of $12.75 or the amount she lost!
) Beth wants to determine a 99 percent confidence interval for the true proportion p of high school students in the area who attend their home basketball games. Out of n randomly selected students she finds that that exactly half attend their home basketball games. About how large would n have to be to get a margin of error less than 0.01 for p
Answer:
n has to be at least 16577.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
Out of n randomly selected students she finds that that exactly half attend their home basketball games.
This means that [tex]\pi = 0.5[/tex]
99% confidence level
So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].
About how large would n have to be to get a margin of error less than 0.01 for p
We have to find n for which M = 0.01. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.01 = 2.575\sqrt{\frac{0.5*0.5}{n}}[/tex]
[tex]0.01\sqrt{n} = 2.575*0.5[/tex]
[tex]\sqrt{n} = \frac{2.575*0.5}{0.01}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.575*0.5}{0.01})^2[/tex]
[tex]n = 16576.6[/tex]
Rounding up
n has to be at least 16577.

Hey There!
So the first step is to solve for the figure with a length of 9 and a width of 15
15x9=135
The other figure has a length of 12 and a width of 6

1. The average length of all the trout in a river is 60 cm. This data summary represents a ____________________(parameter/statistic).
2. If the Hamilton High School freshman class is the sample in a statistical study, then which is not a possible for the study?
A. The student body of Hamilton High School
B. The students in Hamilton High School's district
C. The students in Ms. Anderson's science class
D. All freshman students in the state
Answers:
ParameterC. The students in Ms. Anderson's science class==========================================================
Explanation for problem 1
If all we're concerned with are the trout in this river, and this river only, then we are measuring the parameter population mean value of 60 cm. Parameters always go with populations; while statistics go with samples.
A quick way to remember:
parameter and population both start with pstatistic and sample both start with s----------------------------------------------------------
Explanation for problem 2
This question seems to be missing a key word. The portion that reads "then which is not a possible for the study?" seems to have a missing word where the blank is shown below
then which is not a possible _____ for the study?
I think "population" should be put into the blank. If that's the case, then choices A, B, and D are all possible populations here. They are larger than the sample of freshmen at this high school. Notice how the students in Ms. Anderson's class is a smaller set compared to the set of all freshmen at Hamilton High School. The sample must always be smaller than the population, or phrased another way, the population must always be larger than the sample.
So this is why choice C is the answer.

There are 12 students in an art class. They have 5 packs of crayons to share equally. How much of a pack of crayons will each student get?
Answer:
41%
Step-by-step explanation:
5 packs of crayons split among 12 people means we divide 5 by 12.
[tex]\frac{5}{12} = .4166666667[/tex]
we can round that decimal number to .41 which can be turned into a percentage by moving the decimals place.
.41 = 41%
help asap find the area of this trapazoid
Step-by-step explanation:
here you have the answers
Answer:
[tex]A=12[/tex]
Step-by-step explanation:
The formula to find the area of a trapezoid is,
[tex]A=(\frac{b_1+b_2}{2})(h)[/tex]
Where ([tex]b_1[/tex]) and ([tex]b_2[/tex]) represent the two bases of the trapezoid, and ([tex]h[/tex]) represents the hieght of the figure. As one can see on the coordinate plane,
[tex]b_1=2\\\\b_2=4\\\\h=4[/tex]
Substitute in the given values, and solve,
[tex]A = (\frac{b_1+b_2}{2})(h)\\\\A = (\frac{2+4}{2})(4)\\\\A = (\frac{6}{2})(4)\\\\A = (3)(4)\\\\A = 12[/tex]
In a cooler there are 5 orange juices, 2 apple juices and 6 grape juices. In a large bag there are 2 ham sandwiches and 7 turkey sandwiches.
If you choose a random juice from the cooler and a random sandwich from the bag, what is the probability you get orange juice and a ham sandwich? Round your answer to the nearest hundredth (2 decimal places).
Answer:
10/117 or 8.55% or 0.09
Step-by-step explanation:
5/13 x 2/9 = 10/117
The probability you get orange juice and a ham sandwich is,
⇒ 10/117
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Given that;
In a cooler there are 5 orange juices, 2 apple juices and 6 grape juices. In a large bag there are 2 ham sandwiches and 7 turkey sandwiches.
Hence, Total number of juice in a cooler = 5 + 2 + 6 = 13
And, Total number of sandwiches = 2 + 7 = 9
Thus, The probability you get orange juice and a ham sandwich is,
⇒ 5 / 13 × 2 / 9
⇒ 10/117
