75d+8w+25
Part A)
75 and 8 are coefficients because coefficients are the numbers before and multiplied to the variable.
d and w are variables because variables aresymbols to represent the unknown numbers.
25 is the constant because constants are not affected by the variable.
Part B)
75d+8w+25
75(5)+8(48)+25 replace the variables
375+384+25 multiply
784 add
Part C)
No, because his stipend is a constant, and constants are not affected by the variable.
Just multiply out the given expression, combine like terms and arrange them in descending order by powers of x.
<span>2x(3x-2)+5(3x-2) => 6x^2 - 4x + 15x - 10
Combining like terms results in 6x^2 + 11x - 10 (answer)</span>
Answer:
test statistic.
Step-by-step explanation:
The chi-square (
) test is a non-parametric statistical test(also known as Goodness of fit test) which is used to determine if a distribution of observed frequencies differs from the expected frequencies.
Chi-square statistic uses either nominal (categorical) or ordinal level data.
Hence, When determining how well an observed set of frequencies fits an expected set of frequencies, the test statistic is
test statistic.
Answer:
60.75
Step-by-step explanation:
First, you need to see how much one rose costs.
33.75/15 is 2.25
Next, you need to find out how many 27 roses costs.
2.25*27 is 60.75
Now you have your answer.
Hope this helps and is right!
Answer:
.0625 or A
Step-by-step explanation:
You have to work out the mean. (The simple average of those numbers) Then for each number subtract the Mean and square the result. Then work out the average of those squared differences.
