Answer:
$15.90
Step-by-step explanation:
Richardo saved $80 from his job.
Subtract the change he received by how much money he has.
$80-$16.40=$63.60
Then, since he bought 4 games, you will divide $63.60 by 4.
Therefore resulting in my answer of $15.90
Y=-2/1+0, or just y=-2/1 because it goes through 0 so it really makes no difference
Answer: 16
Step-by-step explanation:
Standard deviation is 2
Margin error for the problem is 1
Probability 95%, that means thet the siginficance level α is 1 – p
α = 1 – 0.95 = 0.05
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.05/2) = Z(0.025)
Using a z table Z = 1.96
Now, replacing in the equation and find n
1 = 1.96 * 2/ √n
1 = 3.92 / √n
√n = 3.92
n = 3.92^2
n = 15.36 = 16
i hope this work for you
Your question is:
Then, the above formula equate:
Factor out 8 from the numerator we get:
Factorization of the denominator:
Simplifying the numerator and the denominator by (u-9) we get:
Number of cookie boxes bought by James = 5
Number of cakes bought by James = 2
Cost of each cakes = $4
Total bill paid by James = $28.50
Let us assume the cost of the each boxes of cookies = x
Then
5x + (2 * 4) = 28.50
5x + 8 = 28.50
5x = 28.50 - 8
5x = 20.50
x = 20.50/5
= 4.10
So we can see from the above deduction that the cost of each boxes of cookies bought by James is $4.10
