Step-by-step explanation:
s=(4+6t)3/2
t=2s
t is seconds
s is meters
s=(4+6×2)3/2
=(4+12)3/2
=16×3/2
s=24m
Answer:
- (b) x- intercept is -1/3; y-intercept is -3/2
Step-by-step explanation:
<u>Given function:</u>
<u>x- intercept is:</u>
- y = 0 ⇒ -9x = 3 ⇒ x = -1/3
<u>y-intercept is:</u>
- x = 0 ⇒ -2y = 3 ⇒ y = -3/2
Correct answer choice is (b)
Answer: 
Step-by-step explanation:
The confidence interval for population mean is given by :-

Given : Sample size :
, which is a large sample , so we apply z-test .
Sample mean : 
Standard deviation : 
Significance level : 
Critical value : 
Now, a confidence interval at the 95% level of confidence will be :-

Answer:
1/7^2
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
a^-b = 1/a^b
__
Then your expression simplifies to ...
