Answer:
D. a = 3 1/2
Step-by-step explanation:
Plug in values
10 = 2a +3
Subtract 3 from both sides
7 = 2a
Divide both sides by 2
3 1/2 = a
There are 5 shelves in the bookcase.
2/5 of one shelve is occupied.
That would be:
2/5*1/5=2/25 of all shelves
7/2 is more than 1, so it refers to the bookcase instead
of one shelve. The same with 11/10.
So the total is:
2/5+7/2+11/10 = 5
So all shelves are completely full.
So there is no room for any other book.
Answer:
$3066
Step-by-step explanation:
We have been given that employees in 2012 paid 4.2% of their gross wages toward social security (FICA tax), while employers paid another 6.2%. We are asked to find the amount paid by an employee earning $73,000 per year toward social security.
To find the amount paid by an employee with annual gross earnings of $73,000, we need to find 4.2% of $73,000.
Therefore, the employee will pay $3066 toward social security out of their gross wages.
Answer:
The null hypothesis is that there is no difference in the mean number of male and female cats
H₀; μ₂ - μ₁ = 0
Step-by-step explanation:
The given parameters are;
The given percentage of male stray cat population = 50%
The given percentage of female stray cat population = 50%
The number of areas the researcher visits, n = 15
The number of stray male cats he finds = 11
The kind of test to be performed = Sign test
The significance level, α = 0.05
A) Therefore the null hypothesis is H₀; μ₂ - μ₁ = 0
The alternative hypothesis is Hₐ; μ₂ - μ₁ ≠ 0.
Answer:
there is no such number
