The FitnessGram PACER Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The test is used to measure a student's aerobic capacity as part of the FitnessGram assessment. Students run back and forth as many times as they can, each lap signaled by a beep sound. The test get progressively faster as it continues until the student reaches their max lap score. The PACER Test score is combined in the FitnessGram software with scores for muscular strength, endurance, flexibility and body composition to determine whether a student is in the Healthy Fitness Zone™ or the Needs Improvement Zone™.

Answers
this one makes the most sense :)
Answer: Someone who sells tickets is always in the ticket wagon, which is stationery in spite of its wheels.
Step-by-step explanation: Do usage of the comma in answers C , and D are incorrect , so that leaves us with answers A and B , in option A stationery is miss spelled so your answer would be : Someone who sells tickets is always in the ticket wagon, which is stationery in spite of its wheels.
a. Create a real world scenario of a study with a population mean and a population standard deviation. Include the information that a random sample of a given size (greater than 30) was selected from the population.
b. Check the conditions for the assumptions about the sampling distribution.
c. Draw, label and describe the sampling distribution in context.
Answers
Answer:
The t-score has the same interpretation as the z-score. It measures how far in standard deviation units \stackrel{-}{x} is from its mean μ. For each sample size n, there is a different Student’s t-distribution. The degrees of freedom, n – 1, come from the calculation of the sample standard deviation s. Remember when we first calculated a sample standard deviation we divided the sum of the squared deviations by n − 1, but we used n deviations \left(x-\stackrel{-}{x}\text{values}\right) to calculate s. Because the sum of the deviations is zero, we can find the last deviation once we know the other n – 1 deviations. The other n – 1 deviations can change or vary freely. We call the number n – 1 the degrees of freedom (df) in recognition that one is lost in the calculations. The effect of losing a degree of freedom is that the t-value increases and the confidence interval increases in width.
Properties of the Student’s t- Distribution 0.05, 95% level of confidence, we find the t-value of 1.96 at infinite degrees of freedom.

Answers
Answer:
£ 559.39
Step-by-step explanation:
To know the actual cost of replacing the flooring with new laminate, we must first obtain the total area of the floor. This can be obtained as follow:
1. Determination of the area of class room
Length (L) = 8.8 m
Breadth (B) = 220 cm
Area of class (A₁) =?
Next, we shall convert 220 cm to m. This can be obtained as follow:
100 cm = 1 m
Therefore,
220 cm = 220 cm × 1 m / 100 cm
220 cm = 2.2 m
Finally, we shall determine the area of the class as follow:
Length (L) = 8.8 m
Breadth (B) = 2.2 m
Area of class (A₁) =?
A₁ = L × B
A₁ = 8.8 × 2.2
A₁ = 19.36 m²
Therefore, the area of the class room is 19.36 m²
2. Determination of the area of storage cupboard
Length (L) = 2.3 m
Breadth (B) = 2.1 m
Area of cupboard (A₂) =?
A₂ = L × B
A₂ = 2.3 × 2.1
A₂ = 4.83 m²
Thus, the area of the cupboard is 4.83 m²
3. Determination of the total area of the floor.
Area of class (A₁) = 19.36 m²
Area of cupboard (A₂) = 4.83 m²
Total area (A) =?
A = A₁ + A₂
A = 19.36 + 4.83
A = 24.19 m²
The total area of the floor is 24.19 m²
4. Determination of the cost.
1.6 m² = £ 37
Therefore,
24.19 m² = 24.19 m² × £ 37 / 1.6 m²
24.19 m² = £ 559.39
Therefore, it will cost £ 559.39 to replace the flooring with new laminate.

On Saturday and Sunday jarrod went running and burned a total of 6475 calories he burned 320 of those calories on Saturday which addition equation could be used to find the number of calories c jarrod burned on Sunday
A 647.5+c=320
B. 320 + c = 647.5
C. 320 + 647.5=c
D. 647.5 + 320 =c
Answers
Answer:
The answer is B.
Step-by-step explanation:
It is saying that 647.5 calories is the total amount and 320 is a part of it. so when you do 647.5-320, it becomes 327.5 and that is c. You can only do this with the equation that letter B is saying.
When Lila conducted an experiment on citywide pond water, all of her samples came from the pond in her uncle's backyard. Explain her error.
Answers
Her area of study is too narrow. There are other sources of water in the city that she is not considering. So her sample is too biased leaning toward the Uncle's pond water, and that leaves out every other source. We say that the Uncle's source of water is over-represented while the other sources are completely under-represented.
Let's put it this way: We have a hypothetical city that has 100 acres of pond water either in or surrounding the city limits. If the Uncle's pond only represents 1% of this, then she's ignoring the other 99% of the ponds.
What Lila needs to do to to fix this error is to draw up a map of each major pond and mark those ponds with numbers 001,002,...998,999. In this example, there are 999 ponds. Then she needs to either use a random number table or computer software to help randomly generate values to help select the ponds. Doing so will ensure that she spans a good portion of the city and not stay focused on just the narrow area of her Uncle's backyard.
The reason why she needs to enlarge her area of study is because the results of her Uncle's pond study may lead to the wrong conclusion of the city overall. Let's say his pond is contaminated somehow, and it's only his pond that's the unfortunate one. She would likely see the pond is contaminated and conclude that the whole city's water is ruined as well, which isn't the case. Or we could have nearly the entire city's pond water in trouble, but her Uncle's pond is one of the lucky ponds not to get contaminated. We can see that Lila would likely conclude that no action needs to be taken to clean up the city's water sources, which is also not the case.
If Lila only cared about her Uncle's pond, then that pond (and perhaps immediate close surrounding area) would be her population of study. However, her study is about citywide pond water which is why she needs to extend to other places in the city or in the outer surrounding areas.
What happens to a 44-degree angle if you rotate it 90 degrees counterclockwise? Explain your answer.
Answers
Answer:
it would melt
Step-by-step explanation:
at 40 degrees, the angle will stay in its natural shape. if increased to 90 degrees on the counter, and with the wisdom of mr. clock, the angle will start to warp, and lose its shape. evidently, if the angle is heated at a steady 90 degrees, the melting process will occur, and it will make a mess on your counter. thats why, when melting angles, I recommend putting it in a container, so as to not make too big of a mess.

A large software development firm recently relocated its facilities. Top management is interested in fostering good relations with their new local community and has encouraged their professional employees to engage in local service activities. They believe that the firm's professionals volunteer an average of more than 21 hours per month. If this is not the case, they will institute an incentive program to increase community involvement. A random sample of 24 professionals yields a mean of 22 hours and a standard deviation of 2.22 hours.
12 13 14 14 15 15 15 16 16 16 16 16
17 17 17 18 18 18 18 19 19 19 20 21
The sample has a mean of 16.6 hours and a standard deviation of 2.22 credit hours.
At α = 0.05,
I. we reject the null hypothesis.
II. we fail to reject the null hypothesis.
III. the firm shouldn't need to institute an incentive program because the evidence indicates that professional employees volunteer an average of more than 15 hours per month in their local community.
a. II and III
b. I and III
c. II only
d. I only
e. III only
Answers
Answer:
B. i and iii
Step-by-step explanation:
There are mistakes in your question. But I solve this problem using the average mean of 15 because that is what is contained in the solution
Hypothesis
H0: u <= 15
H1: u > 15
Mean of x = 16.6
S = 2.22
Test statistic used is t test
16.6 - 15 / 2.22/√24
= 3.531
We find the critical value
Degree of freedom = 24-1 = 23
This is a one tailed test
Critical value = 1.714
We find p value using Ms excel T distribution function
= 0.000894
To make the decision
3.531 > 1.714 so we conclude that
I.) Reject null hypothesis
Iii) conclude an average if more than 15 hours is volunteered per month. So no need to institute the program.
The answer option Is B

Speed = 100/Time
Step-by-step explanation:
(a). Speed is a function of time : As seen from equation (1) Speed of the students varies according to the value of time. So, This a true statement.
(b). Time is a function of distance : Distance is not varying in the equation (1), it is fixed to be 100. So, time is not a function of distance because here the distance is made constant. So, This is false statement.
(c). Speed is a function of number of students racing : Speed is not depending on the number of students racing so sped is independent of the number of the students racing. Therefore, Speed is not a function of number of students racing. This is False statement.
(d). Time is a function of speed : As seen from equation (1) Time of the students varies according to the value of their speed. So, This a true statement.
Hence, the true statements are (a) and (d)

The object above is made up of 1-inch cubes. What is the surface area of the object?
A.
52 inches2
B.
63 inches2
C.
48 inches2
D.
54 inches2
Answers
Answer:
52 inches2
Step-by-step explanation:
The figure is a rectangular solid with length (L) = 4 in., width (W) = 3 in. and height (H) = 2 in. To find the surface area, first find the area of each side and then add them together.
Sides 1 & 2 will have an area equal to L × W = 12 inches2.
Sides 3 & 4 will have an area equal to L × H = 8 inches2.
Sides 5 & 6 will have an area equal to W × H = 6 inches2.
The total surface area is
(2 × 12 in.2) + (2 × 8 in.2) + (2 × 6 in.2)
= 24 in.2 + 16 in.2 + 12 in.2
= 52 inches2.
