What does please stat on the dot mean?

Anyway yeah he messed up on step 1 because he should have added the two on the other side instead of subtracting.

The real answer is 9.7

Answer:

Mitch made a mistake in step 1.

Step-by-step explanation:

7.7 = w - 2

Add two to both sides

7.7 + 2 = w - 2 + 2

9.7 = w is the right answer.

I need help, I dont know how to convert ratios into decimals and percentages [EX: write the ratio 5 to 8 in a decimal/percent]

Anon25 [30]

Fractions are just unsimplified numbers. For example 5/8 is just 5 divided by 8 so 0.625. To find the percent from that you move the decimal two places to the right making it 62.5%. Hope this helps!

Priya's cat is pregnant with a litter of 5 kittens. Each kitten had a 30% chance of being chocolate brown. Estimate the probabil

aniked [119]

Answer:

So, the probability is P=0.3087.

Step-by-step explanation:

We know that Priya's cat is pregnant with a litter of 5 kittens, so n=5.

Each kitten had a 30% chance of being chocolate brown.

We get that p=0.3 and q=1-0.3=0.7.

We calculate the probability that exactly 2 kittens will be chocolate brown, so k=2.

We use the formula:

$\boxed{P(X=k)=C_k^n\cdot p^k\cdot q^{n-k}}$

we get

$P(X=2)=C_2^5\cdot 0.3^2\cdot 0.7^3\\\\P(X=2)=\frac{5!}{2!(5-2)!}\cdot 0.03087\\\\P(X=2)=10\cdot 0.03087\\\\P(X=2)=0.3087\\$

So, the probability is P=0.3087.
