Answer: 200
Step-by-step explanation:
174 rounded to the nearest hundred is:
200
When rounding to the nearest hundred, like we did with 174 above, we use the following rules:
A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.
B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

Answer:
About 1.2 units long
Step-by-step explanation:
Circumference of a cirxle formula:
2*pi*r=C
Pi and Circumference are given so lets plug those in,
2*pi*r=7.85
6.28318530718*r=7.85
Divide both sides with 6.28318530718
r=1.24936630327
Answer:
There is significant evidence that treatment will create effect on the subject. Hence We reject H0
Step-by-step explanation:
H0 : μ = 37
H1 : μ ≠ 37
μ = 37 ; σ = 7 ; sample size, x = 51 ; sample size, n = 1
Decision region :
If P value < α ;
Reject H0
Using the Z test statistic :
Zstatistic = (x - μ) ÷ (σ / √n)
Zstatistic = (51 - 37) ÷ (7 / 1)
Zstatistic = 14 ÷ 7
Zstatistic = 2
Obtaining p value from Zstatistic using the p value calculator ;
Zscore = 2 ; 2-tailed test, significance level = 0.05
P value = 0.0455
Zcritical at α = 0.05 for a 2 - tailed test = 1.96
0.0455 < 0.05
There is significant evidence that treatment will create effect on the subject. Hence We reject H0

Step-by-step explanation:
<u>Expression:</u>
- 2∛x - 5√z + y² =
- 2∛27 - 5√64 + (-4)² =
- 2(3) - 5(8) + 16 =
- 6 - 40 + 16 =
- -18
12% of Gilbert's contribution is 600
0.12x = 600
x = 600/0.12
x = 5000 <==
