A. 2/7
B. 3/2
C. 2/3
D. 3/5
E. 5/9
NO LINKS
Answers
Answer:
B and D
Step-by-step explanation:
A terminating decimal differs from a repeating decimal in that ; terminating decimals have a finite number of numbers after a decimal point whereby repeating decimals Don not have a fine number of numbers after the decimal point.
Given :
A. 2/7 = 0.2857...
B. 3/2 = 1.5
C. 2/3 = 0.6666...
D. 3/5 = 0.6
E. 5/9 = 0.5555...
B and D are terminating decimal values.

A manufacturer wants to inspect the absorption capacity of a new sponge. Based on past data, the average sponge could absorb 3.5 ounces. After the redesign, the absorption amounts of a sample of 10 sponges were (in ounces): 4.1, 3.7, 3.3, 3.5, 3.8, 3.9, 3.6, 3.8, 4.0, and 3.9. At a level of significance of 1%, would you claim that the new design is better than the old one?
Requried:
a. No because we don't reject the Null Hypothesis at Alpha = 0.01
b. Yes because we reject the Null hypothesis at Type 1 error = 1%
c. Yes because the cut-off is more than the sample mean
d. No because the cut-off is less than the sample mean
Answers
Answer:
c. Yes because the cut-off is more than the sample mean
Step-by-step explanation:
The null and alternate hypotheses are
H0 : u= 3.5 ounces vs Ha: u > 3.5 ounces
The mean and standard deviation of the sample are calculated to be 3.76 and 0.24
The test statistics is
t= x`- u/s√n
= 3.76-3.5/0.24/√10
= 0.26/0.07589
=3.426
The critical region for z test is z > ± 2.33
The critical region for t test is t > ± 2.82 for 9 d.f
For both the tests( z and t) the test statistic =3.426 lies in the critical region.
Hence we reject H0 and accept the hypothesis that the new design is better than the old one at a level of significance of 1%.
cut-off = mean + 3 times the standard deviation
= 3.76 + 3* 0.24
cut-off =4.48
Yes, the cut off is more than the sample mean.
So choice c is the best option.

harrison bought a 10 foot ramp to load his dirt bike into the back of his truck. the ramp hooks to the 3 foot high tailgate. how far away from the tailgate doe the ramp sit in the ground?
Answers
Answer:
9.54 feet
Step-by-step explanation:
Using Pythagoras rule :
Length of ramp = 10 feets = hypotenus
Hypotenus² = opposite² - adjacent²
d² = 10² - 3²
d² = 100 - 9
d² = 91
d = √91
d = 9.5393920
d = 9.54 feets

The most common railroad boxcars are 52 feet long, 9.5 feet wide, and 11 feet
tall. What is the volume, in cubic feet, of common railroad boxcars?
Answers
Answer:
Box volume ≈ 5,434 ft³
Step-by-step explanation:
Given: Railroad boxcars are 52 feet long, 9.5 feet wide, and 11 feet
To find: The volume, in cubic feet, of common railroad boxcars
Solution: To find the volume of a box, simply multiply the length, width, and height.
52 × 9.5 × 11 = 5434
Therefore, the volume, in cubic feet, of common railroad boxcars is 5,434 ft³
For dimensions that are relatively small whole numbers, calculating volume by hand is easy.

The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
Ranks in a dancing competition: This is an illustration of ordinal measurement since the values can be ranked or ordered, but the differences between the values are meaningless.
Basketball player heights: Although there isn't a genuine zero point, the values have significant variances between them, making this an example of an interval measurement.
Monthly electric bills are an example of a ratio measurement because there are real zero points and significant variances between the values.
Calendar day count: Because the values are categorical and cannot be ranked or sorted, this is an example of a nominal measurement.
Score on an aptitude test: This is an instance of an interval measurement because there are actual disparities between the results, but no actual zero point.

Number 5 is L because you have 18 coins but you only want to find the probability of the pennies. So take 3/18 and simplify to 1/6 by dividing both the numerator and the denominator by 3.
Number 6 can be (-6x - 3), just use the distributive property on the original expression.
Answer:
5. I.
6. -6x - 3
Step-by-step explanation:
For number five you add up all the coins, which equals 18. Secondly, you see how many pennies there are. There are 3 so the answer is 3/18. Then you simpy into 1/6.
For number six, you want to multiply 3 by -2x and then multiply 3 by -1. You will get the answer -6x -3. If you see a number outside the parenthesis then multiply by the number inside of it.
