You are given that XW and WT are similar and they share and angle W.
You need to know another set of sides are similar.
The answer would be C. VW ≅ RW
1/5 = 0.2
2/8 = 0.25
1/5 is less than 2/8
2/8 is greater than<span> 1/5</span>
<span>1/5 </span><<span> 2/8</span>
<span>2/8 </span>><span> 1/5</span>
Answer:
0.0537
Step-by-step explanation:
This follows a binomial distribution with : n
Number of trials 'N' = 12 ; Probability of success (difference between speakers) 'p' = 1/2 or 0.5 ; Probability of failure (no difference b/w speakers) = 1/2 or 0.5 ; No of success 'r' = 3
P (X = 3) = 
= 12C3 (0.5)^3 (0.5)^9
0.0537
Lol it’s 3.75. 3*4 is 12 leaving 3.
Answer:
We want to construct a confidence interval at 99% of confidence, so then the significance level would be
and the value of
. And for this case since we know the population deviation is not appropiate use the t distribution since we know the population deviation and the best quantile assuming that the population is normally distributed is given by the z distribution.
And if we find the critical value in the normal standard distribution or excel and we got:

And we can use the following excel code:
"=NORM.INV(0.005,0,1)"
Step-by-step explanation:
For this case we have the following info given:
