Answer:
n = 484
Step-by-step explanation:
If Confidence Interval CI = 95 % then α = 5% and α/2 = 2,5 %
α/2 = 0,0125
MOE for normal distribution is:
MOE = z * σ/√n
For α/2 = 0,0125 ⇒ z(score) = -2,2
MOE = |-2,2| * 4/√n
0,4*√n = 8,8
√n = 8,8 / 0,4
√n = 22
n = 484
Answer:
Option 3,5 are under first expression and Option 1,2 are under second expression.
Step-by-step explanation:
1). 
2). 
3). 
4). 
5). 
6). 
Hmm, so they seem to be increaeing by powers of 5
10=2 times 5
25=5 times 5
35=7 times 5
60=12 times 5
so maybe it is
nth term=5(n+2) or 5n+10
lets try it
0th term
5(0)+10
0+10=10
corrrect
3rd term
5(3)+10
15+10
25
correct
so the function is
f(x)=5(x+2)
In x^7•x^4, how many x’s are multiplied together? (There’s 7 in the first factor and 4 in the second.)
x^7•x^4 = x^__? This is your a-value.
Similarly, y^2•y^5 = y^__? How many y’s are there in total being multiplied? This is your b-value.
Answer:
B)1
Step-by-step explanation:
When you replace x with three your equation is 2*3-5. By doing order of operations you multiply 2*3 and get 6 then subtract 5 getting 1.
