This information provides the number of students who read a certain range of books. Those ranges are provided 0 to 4 (inclusive) 5 to 9 and 10-14.
Since 9 books or more covers two bins, this cannot be the answer.
The information doesn't offer specific values just ranges, so both the mean and median cannot be determined.
So the answer is C, the number of students who read 4 books or fewer.
The linear function rule is d = 103t
<h3>What Speed is?</h3>
The ratio of the distance travelled to the time taken is known as speed.
The formula for calculating the distance traveled is expressed as:
Speed = 618ft/6s
Speed = 103ft/s
Recall that:
d = st
Substitute s = 103 into the expression to have:
d = 103t
Hence the linear function rule is d = 103t

140,000 cm³ of plywood is needed to make the prop.
Explanation:
- The dimensions of the required box are 70cm × 40cm × 50cm.
- So we take the length equals 70cm, the width is equal to 40cm and the height is 50cm. The volume of this box is calculated by multiplying the given box's length, its width, and its height. The question does not provide which measurement is which but ultimately the volume will be equal no matter what the case.
- Volume of box = Length × Width × Height = 70cm × 40cm × 50cm = 140,000 cm³.
- So 140,000 cm³ of plywood is needed to make the prop in the play
Answer:
Exterior angle of a decagon will be 36°
Step-by-step explanation:
Measure of all interior angles of a polygon is represented by (n - 2)×180°
where n is the number of sides of the polygon.
Now we have to calculate the exterior angle of a regular decagon.
As we know exterior angle of polygon is supplementary of the interior angle.
So we will calculate interior angle first.
Sum of interior angles of decagon = (n - 2)×180° = 8×180° = 1440°
Since decagon is regular so all angles will be same.
So one angle of decagon = 1440 ÷ 10 = 144°
Now exterior angle = 180 - 144 = 36°
Each exterior angle of a decagon will be 36°.

Trade associations, such as the United Dairy Farmers Association, frequently conduct surveys to identify characteristics of their membership. If this organization conducted a survey to estimate the annual per-capital consumption of milk and wanted to be 95% confident that the estimate was no more than 0.5 gallon away from the actual average, what sample size is needed? Past data have indicated that the standard deviation of consumption of approximately 10 gallons.
Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The margin of error is 
The confidence level is 
%
Given that the confidence level is 95% the level of significance is mathematically represented as
%
Next we obtain the critical value of 
from the normal distribution table , the values is 
The reason we are obtaining critical values of
instead of
is because
represents the area under the normal curve where the confidence level interval (
) did not cover which include both the left and right tail while
is just the area of one tail which what we required to calculate the sample size
Now the sample size is mathematically represented as
![n = \frac{[Z_{\frac{\alpha }{2} }] ^2 * \sigma ^2}{MOE^2}](https://tex.z-dn.net/?f=n%20%20%3D%20%20%5Cfrac%7B%5BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%5D%20%5E2%20%2A%20%20%5Csigma%20%5E2%7D%7BMOE%5E2%7D)
