10
Step-by-step explanation:
30 - 1, 2, 3, 5, 10, 15, 30
100- 1, 2, 4, 5, 10, 20, 25
Answer:
48
Step-by-step explanation:
821 rounded down to 800
17 rounded up to 20
820/20 =41
20x41=820
17 x 41 = 697
17 x 51 = 867
Midpoints
697+867/2 = 782
41 +51/2 = 46
46 x 17 = 782
47 x 17 = 799
48 x 17 =816
49 x 17 =833
50 x 17 =850
So, the highest number is 48.
The closest we can get is 48 x 17=816 & without going over 821.
Answer:
21 adults and 139 children
Step-by-step explanation:
x=adult (8$)
y=child (5$)
8x + 5y =863
x+y=160
-x -x (subtract x on both sides)
y= -x + 160
plug that in for y on the other equation
8x + 5(-x + 160) =863
distribute 5 to both
8x + -5x + 800 = 863
combine both x values
3x + 800 = 863
-800 -800 (subtract on both sides)
3x = 63
divide by 3 on both sides
x = 21 adults
now plug x in one of the equations
21 + y = 160
-21 -21
y=139 children
Answer:
A. n = 22
Step-by-step explanation:
Hello!
The researcher conducted a one-sample t-tas with the following hypotheses:
H₀: μ = μ₀
H₁: μ ≠ μ₀
α:0.05
The one-sample t-test has "n-1" degrees of freedom and since the hypotheses are two-tailed you know that the rejection region will be divided into two tails with "α/2" for each tail. ± 
If α:0.05 then α/2:0.025 and 1-α/2= 0.975
Using the given sample sizes as a reference you look in the table for the corresponding DF for an accumulated probability of 0.975
For n = 22 
For n= 21 
For n= 20 
The correct answer is a) n= 22
I hope this helps!
