Answer:
2,100 cubic feet
Step-by-step explanation:
20 × 15 × 8 = 2,400
20 × 15 × 1 = 300
2,400 - 300 = 2,100
Answer:
C
Step-by-step explanation:
There is a common ratio between consecutive terms
r = 24 ÷ 16 = 36 ÷ 24 = 54 ÷ 36 = 1.5 = 
This indicates the sequence is geometric with nth term ( explicit formula )
f(n) = a₁
where a₁ is the first term and r the common ratio
Here a₁ = 16 and r =
, then
f(n) = 16
→ C
If there is a decimal, you usually round when graphing.
The multinomial setting goodness of fit test allows to check whether the distribution of a sample corresponding to a qualitative variable (or discrete quantitative variable) is consistent with the expected results.
The Chi-square goodness of fit test is a statistical hypothesis test used to determine whether a variable is likely to come from a specified distribution or not. It is often used to check whether the sample data is representative of the full population or is it biased.
The degrees of freedom for the chi-square goodness of fit is calculated by using the following formula: df = (r-1)(c-1) where r is the number of rows and c is the number of columns. The following conditions are the conditions required: The sampling method should be simple random sampling. The variable being observed is categorical. The expected value of the number of sample observations for each variable is at least 5.
Therefore, The multinomial setting goodness of fit test allows to check whether the distribution of a sample corresponding to a qualitative variable (or discrete quantitative variable) is consistent with the expected results.

<u>Answer:</u>
The ratio of the complement of x to the supplement of x is 2:5. The value of x is 30
<u>Solution:</u>
It is given that x represents the measurement of an acute angle in degrees. It is also given that the ratio of the complement of x to the supplement of x is 2:5.
Since it is given that x is an acute angle it means that it has to be less than 90.
Complement of an angle = 90 - x
Supplement of an angle = 180 - x
In this case it is given that the ratio of the complement of x to the supplement of x is 2:5
So we can write the relation as follows:

Therefore the value of x is 30.
