7
This means the cube root of 343 which is 7.
Evaluate A² for A = -3.
(-3)² = (-3) * (-3) = 9
Your answer is 9.
If the question is, however, evaluate A2, which is 2A, for A = -3, then the answer is:
2A = 2(-3) = -6.
Ok, first set this up as an equation with your given variables. You know that Sylvie bought 1 container of cream cheese, which is $2.95, and you know that Sylvie spent $7.50
<u>(my best assumption is this is the subtotal)</u><u /> on the cream cheese and 13 bagels. As an equation, it would come out as:

To start solving the algebraic equation, wou can subtract 2.95 on both sides, resulting as

Now, to get "b" by itself, you must divide
13 on both sides, resulting as

This will answer your question as the cost of 1 bagel would be
$0.35 per bagel.
Answer:
The statistic for this system of hypothesis is given by:
If the statistic is equal to 1 then that means
and we don't have enough evidence to conclude that the two population variances and deviations are different.
Step-by-step explanation:
System of hypothesis
We want to test if the variation for a group1 is equal to another one 2, so the system of hypothesis are:
H0:
H1:
Calculate the statistic
The statistic for this system of hypothesis is given by:
If the statistic is equal to 1 then that means
and we don't have enough evidence to conclude that the two population variances and deviations are different.
~ Convert the decimal number to a fraction by placing the decimal number over a power of ten.
~ Next, add the whole number to the left of the decimal.
2 25/100
~ Reduce the fractional part of the mixed number.
2 1/4
Answer: 2 1/4
Hope this helps :)
