Hence the correct answer is C) -23
Further explanation:
We have to put the values of m and n into both expression first separately and then multiply the answers.
Given expressions are:
The values are:
Putting the values in expression 1:
Putting the values of m and n in second expression
Multiplying both expressions:
Hence the correct answer is C) -23

Answer:
x = 15
Step-by-step explanation:
y = family members = 7
x = cost of ticket
7x + 6y = 147
Substitute 7 for y:
7x + 6(7) = 147
7x + 42 = 147
Subtract 42 on both sides:
7x + 42 = 147
- 42 -42
7x = 105
Divide both sides by 7:
7x = 105
x = 15
Answer: 547
Step-by-step explanation: The margin of error formulae is given below as
Margin of error = critical value ×(σ/√n)
Where σ = standard deviation and n is the sample size.
From our question, margin of error = 0.08
Variance is 1.691,
hence σ = √variance = √1.691
= 1.3.
We will be using a z test for our critical value this is because a soft drink manufacturer will always produce drinks more than 30 in numbers.
The critical value for a 85% confidence interval is 1.44.
Hence critical value is 1.44.
By substituting the parameters, we have that
0.08 = 1.44 × 1.3/ √n
0.08 = 1.873/ √n
By cross multiplying
0.08 × √n = 1.873
√n = 1.873/ 0.08
√n = 23.41
n = (23.41)²
n = 547.
Answer:
The domain is all the possible inputs for this function. The range is all the possible outputs for this function.
The line starts at the <em>x-value</em> of 0 and ends at the <em>x-value</em> of 12. Therefore, your domain is D: [0, 12].
The line starts at the <em>y-value</em> of 9000 and ends at the <em>y-value</em> of 0. Therefore, your range is R: [0, 9000].
Hello,
there are some words that I could not read. But:
I support evements are independants.
p(s)=0.2
p(l)=1-0.2=0.8 l=lose
1)0.8*0.2=0.16
2) 0.8²*0.2=0.128
3) 0.8^3*0.2=0.1024
4) 0.2*0.8^(n-1)
