Turn 1/4 into 3/12. Circle 5 of them, and put an x on 3 of them

This question is finding out if you know how to find fractions in simple things. If you have 12 balloons, to circle 5/12 of the balloons means to circle 5 balloons because 5 out of 12, or 5/12, is 5 of the 12 balloons. The other question is asking mark an x on 1/4 of the balloons. If you look at the 12 balloons, then you have 12/12 balloons, but it wants you to only mark an x on 1/4 of the balloons, so what number goes into 12 4 times? It's 3, 3+3+3+3 is 12, so it goes in 4 times, which means that 3/12 is the same thing as 1/4 of the balloons. 1/4 and 3/12 is the same thing, it's just that 1/4 is reduced down more. So you would mark an x on 3 of the 12 balloons, and circle 5 of the 12 ballons

I WILL MARK YOU BRAINLIEST!I REALLY NEED HELP WITH 20 PLEASE HELP ME

Answer:

AP is 11.25 so the answer is F

Step-by-step explanation:

Since they are similar triangles (due to the ~ symbol)

You can write this:

AC/XZ = AP/XQ

since XZ=12

XQ=5

AC=27

you can write:

27/12=AP/5

then cross multiply:

27x5=135

135/12=11.25

AP is 11.25

Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following p

aev [14]

Answer:

P(X < 3) = 0.7443

Step-by-step explanation:

We are given that the random variable X has a binomial distribution with the given probability of obtaining a success. Also, given n = 6, p = 0.3.

The above situation can be represented through Binomial distribution;

$P(X=r) = \binom{n}{r}p^{r} (1-p)^{n-r} ; x = 0,1,2,3,.....$

where, n = number of trials (samples) taken = 6

r = number of success = less than 3

p = probability of success which in our question is 0.3.

LET X = a random variable

So, it means X ~ $Binom(n=6, p=0.3)$

Now, Probability that X is less than 3 = P(X < 3)

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

= $\binom{6}{0}0.3^{0} (1-0.3)^{6-0}+ \binom{6}{1}0.3^{1} (1-0.3)^{6-1}+ \binom{6}{2}0.3^{2} (1-0.3)^{6-2}$

= $1 \times 1 \times 0.7^{6} +6 \times 0.3^{1} \times 0.7^{5} +15 \times 0.3^{2} \times 0.7^{4}$

= 0.11765 + 0.30253 + 0.32414 = 0.7443

Therefore, P(X < 3) = 0.7443.
