Answer:
5
Step-by-step explanation:
This is how far the number is from 0
Answer:
It's A and B
Step-by-step explanation:
Since she took 75% off of her commute time, she has 25% left. 25% as a decimal is 0.25 and 0.25 as a decimal is 1/4.
Also, since it says choose two answers, C and D are not equal to each other.
Answer:
a. True
b. False
c. False
d. True
e. True
Step-by-step explanation:
a.
True,
A 99% confidence interval covers more than a 95% confidence interval.
This is because, more potential values must be allowed within the interval, to be more confident that the true population value falls within the interval
b.
False,
Decreasing the significance level will decrease the probability of making a type 1 error because the probability of a Type I error is the same as α.
c.
False,
The evidence is not sufficient to make a conclusion that µ = 5.
d. True
The probability of making a type II error (failing to reject the null hypothesis when it is actually false) is called β (beta).
The probability of not making this error is 1 - β
1 - β + β = 1
e.
True,
Large sample sizes can decrease the margin of error.
Because the relationship between margin of error and sample size is simple is that when the sample size increases, the margin of error decreases and vice versa
The area (A) of a regular hexagon in terms of its side length s is
... A = (3√3)/2·s²
For a regular hexagon, its side length is equal to the radius of its circumcircle, given here as 10√3 cm. Putting this value in the formula gives
... A = (3√3)/2·(10√3 cm)² = 450√3 cm²
... A ≈ 779.4 cm² . . . . area of the hexagon
Answer:
uh, I think it's 4.13
Step-by-step explanation:
5*sin(65)=4.13 now this seems a bit off but this was the only one that actually worked
