Answer:
$480
Step-by-step explanation:
From the above question, we are told that:
A saleswoman earns 60% commission on all that she sells. Last month she sold $800 worth of merchandise.
The amount of commission (In dollars) she earned last month is calculated as:
60% of $800
= 60/100 × $800
= $480
Therefore, the amount of commission shoe earned last month in dollars = $480
To get a certain percentage as a decimal, all you have to do is divide this percentage by 100.
Applying this on the given question, we will find that:
3.58% = (3.58) / (100) = 0.0358
Comparing the calculated value to the given choices, we will find that the correct choice is:
<span>c) 0.0358</span>

Answer: We can be 95% confident that the true proportion of all college students gain weight in their freshman year.
Step-by-step explanation:
- A 95% confidence interval interprets that a person can be 95% confident that the true population parameter lies in it.
Given : A popular claim, nicknamed "freshman fifteen," states that many college students gain weight in their freshman year.
The 95% confidence interval as 55.9% < p < 78.4%.
Here : Population parameter = p , where p is the proportion of college students gain weight in their freshman year.
Interpretation of 95% confidence interval : We can be 95% confident that the true proportion of all college students gain weight in their freshman year.
Answer:
x=1
y=-3
(1,-3)
Step-by-step explanation:
3x+2y=-3
3x-y=6 then y=3x-6
substitute for y
3x+2(3x-6)=-3
3x+6x-12=-3
reduce
9x=9
x=1
substitute for x
y=3(1)-6
y=-3
