Guys pls help with all the steps ​

Mathematics
1 answer:
Gwar [14]2 years ago
5 0

Step-by-step explanation:

To solve both questions you will have to use the Pythagoras theorem

{c}^{2}  =  {a}^{2}  +  {b}^{2}

c being the hypotenuse

so to find AB we say

{ap}^{2}  =  {pb}^{2}  +  {ab}^{2}

To make AB the subject of the formula, we take PB over. Therefore:

{ab}^{2}  =  {ap}^{2}  -  {pb}^{2}

now we just substitute

{ab}^{2}  =  {13}^{2}  -  {5}^{2}

{ab}^{2}  = 169 - 25

{ab}^{2}  = 144

square root both sides of the equation

ab = 12

We then use the same formula to find AQ(which is a hypotenuse)

{aq}^{2}  =  {ab}^{2}  +   {bq}^{2}

{aq}^{2}  =  {12}^{2}  +  {9}^{2}

{aq}^{2}  = 144 + 81

{aq}^{2}  = 225

square root both sides

aq = 15

UkoKoshka [18]

Answer:

The probability that 8 mice are​ required is 0.2428.

Step-by-step explanation:

Given : A scientist inoculates​ mice, one at a​ time, with a disease germ until he finds 3 that have contracted the disease. If the probability of contracting the disease is two sevenths.

To find : What is the probability that 8 mice are​ required? The probability that that 8 mice are required is nothing ?

Solution :

Applying binomial distribution,

P(X=r)=^nC_r p^rq^{n-r}

Where, p is the probability of success p=\frac{2}{7}

q is the probability of failure q=1-p, q=1-\frac{2}{7}=\frac{5}{7}

n is total number of trials n=8

r=3

Substitute the values,

P(X=3)=^8C_3 (\frac{2}{7})^3 (\frac{5}{7})^{8-3}

P(X=3)=\frac{8!}{3!5!}\times \frac{8}{343}\times (\frac{5}{7})^{5}

P(X=3)=\frac{8\times 7\times 6}{3\times 2\times 1}\times \frac{8}{343}\times \frac{3125}{16807}

P(X=3)=0.2428

Therefore, the probability that 8 mice are​ required is 0.2428.
