Can’t have to outputs for a function
Answer:
26 y + 5
Step-by-step explanation:
Simplify the following:
7 3 y + 4 3 y - 3 y - 2 2 y + 5
7×3 = 21:
21 y + 4 3 y - 3 y - 2 2 y + 5
-2×2 = -4:
21 y + 4 3 y - 3 y + -4 y + 5
4×3 = 12:
21 y + 12 y - 3 y - 4 y + 5
Grouping like terms, 21 y + 12 y - 3 y - 4 y + 5 = (21 y - 4 y + 12 y - 3 y) + 5:
(21 y - 4 y + 12 y - 3 y) + 5
21 y - 4 y + 12 y - 3 y = 26 y:
Answer: 26 y + 5
Answer:
The 95% confidence interval for the difference of the hours worked is [-0.052 , 0.0012]
Step-by-step explanation:
Formula for Confidence interval based on difference =
p1 - p2 ± z × √[p1(1 - p1)/n1] + [p2(1 - p2)/n2]
p1 = proportion for the first group = x/n
= 8.5/10.2
= 0.8333333333
≈ 0.83
n1 = 1000
p2 = proportion for the second group = 6.9/8.1
= 0.8518518519
≈ 0.85
n2 = 1000
Confidence Interval = p1 - p2 ± z × √[p1(1 - p1)/n1] + [p2(1 - p2)/n2]
= 0.83 - 0.85 ± 1.96 √[0.83(1 - 0.83)/1000] + [0.85(1 - 0.85)/1000]
= -0.02 ± 1.96 × √0.83 × 0.17/1000 + 0.85 × 0.15/1000
= -0.02 ± 1.96 × √0.0001411 + 0.0001275
= -0.02 ± 1.96 × √0.0002686
= -0.02 ± 1.96 × 0.0163890207
= -0.02 ± 0.0321224806
-0.02 - 0.0321224806
= -0.0521224806
≈ -0.052
-0.02 + 0.0321224806
= 0.0121224806
≈ 0.012
Therefore, the 95% confidence interval for the difference of the hours worked is [-0.052 , 0.0012]
Answer:
10\frac{7}{12}
Step-by-step explanation:
First thing you want to do is find the common denominator for \frac{1}{3} and \frac{3}{4}. You do this by multiplying to denominators together, so 3*4=12.
Next, multiple the numerators with the opposite denominator. 1*4=4 and 3*3=9.
Now you are left with \frac{4][12] and \frac{9}{12}.
Add those back to your numbers
16\frac{4}{12} - 5\frac{9}{12} = 10\frac{7}{12}
Answer:
2
Step-by-step explanation:
8*8 is 64
Since it looks like the empty box is an exponent, and there are 2 8s being multiplied, the answer is 2
