In the United States, 75 percent of adults wear glasses or contact lenses. A random sample of 10 adults in the United States wil

V125BC [204]

Answer:

0.4745 is the probability that fewer than 8 of the selected adults wear glasses or contact lenses.

Step-by-step explanation:

We are given the following information:

We treat adult adults wear glasses or contact lenses as a success.

P(Adults wear glasses or contact lenses) = 75% = 0.75

Then the number of adults follows a binomial distribution, where

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 10

We have to evaluate:

P(fewer than 8 of the selected adults wear glasses or contact lenses)

$P(x < 8)\\=1 - P(x = 8) - P(x = 9) - P(x = 10)\\=1 - \binom{10}{8}(0.75)^8(1-0.75)^2 - \binom{10}{9}(0.75)^9(1-0.75)^1- \binom{10}{10}(0.75)^10(1-0.75)^0\\=1 - 0.2815-0.1877-0.0563\\= 0.4745$

0.4745 is the probability that fewer than 8 of the selected adults wear glasses or contact lenses.

Dr.Bradley said that my cat Pumpkin was too heavy at 17 pounds and that he should lose weight.After three months on a cat weight

Alexxandr [17]

Answer: The percentage changes is $-11\frac{13}{17} \%$

Step-by-step explanation:

Since the initial weight of the dog = 17 pounds,

After 3 months, the weight of the dog = 15 pounds,

⇒ $\text{ The percentage in the weight of the dog} = \frac{\text{ Initial weight-final weight}}{\text{ initial weight}}\times 100$

⇒ $\text{ The percentage in the weight of the dog} = \frac{15-17}{17}\times 100$

= $-\frac{2}{17}\times 100$

= $-\frac{200}{17}$

= $-11\frac{13}{17}\%$

Why must s-phase occur before mitosis? ...?

stich3 [128]

Here is the answer of the given question above.
S phase happens after G1 phase and this is a crucial period because this is when DNA is copied. G2 phase then happens, which is prior to mitosis. Once this is complete, this then mitosis happens wherein the cells divides the contents of the nucleus between two daughter cells. Hope this answer helps.
