Step-by-step explanation:
let d+e=2 be equation 1
let d-e=4 be equation 2
lets make d the subject in equa 1
d = 2-e equation 3
put equation 3 in 2
2-e=4
e=2-4
e=-2
put e=-2 in equa 1
d-2=2
d=4
e is -2 and d is 4
Answer:
The significance level is 
and since we are conducting a right tailed test we need to find a critical value who accumulate 0.01 of the area in the right of the normal standard distribution and we got:
So we reject the null hypothesis is 
Step-by-step explanation:
For this case we define the random variable X as the number of entry-level swimmers and we are interested about the true population mean for this variable . On specific we want to test this:
Null hypothesis: 
Alternative hypothesis: 
And the statistic is given by:
The significance level is and since we are conducting a right tailed test we need to find a critical value who accumulate 0.01 of the area in the right of the normal standard distribution and we got:
So we reject the null hypothesis is
Answer:
The answer is 4.
Step-by-step explanation:
8/3 ÷ 2/3 = 8/3 x 3/2 = 4
Answer:
W=4
Step-by-step explanation:
When you plug 4 into w, it changes into 4/8 which simplifies to 1/2.
1/2 times 6 is 3.
11+3=14
Honestly it's fun and people need to stop hating on it just because most of the people are toxic and weird. I don't play it, but It's really not worth the hate. People just hate just to hate about it.
Same with ro blox.
