Morgarella [4.7K]

Answer:

The quotient = x + 5 and the remainder = 20

Step-by-step explanation:

$\frac{x^{2}+0-5 }{x-5}=x+\frac{5x-5}{x-5}$

$\frac{5x-5}{x-5}=5+\frac{20}{x-5}$

The quotient = x + 5 and the remainder = 20

Chris is 11 5/6 years old. Marian is 1 1/3 years younger than Chris and Jane is 1 1/4 years younger than Marian. How old is Jane

jarptica [38.1K]

Answer:

Step-by-step explanation:

chris is 11 5/6 years old

marian is 1 1/3 years younger...

(11 - 1) = 10 : (5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2)...so marian is 10 1/2

jane is 1 1/4 years younger then marian...

10 1/2 - 1 1/4...

(10 - 1) = 9 : (1/2 - 1/4 = 2/4 - 1/4 = 1/4)....so Jane is 9 1/4 years <==

The number of surface flaws in a plastic roll used for auto interiors follows a Poisson distribution with a mean of 0.05 flaw pe

ElenaW [278]

Answer:

0.6065

Step-by-step explanation:

Probability mass function of probability distribution : $P(X=x)=\frac{e^{-\lambda} \times \lambda^x}{x !}$

a mean of 0.05 flaw per square foot

Each car contains 10 sq.feet of the plastic roll

Mean = 0.05

Mean = $\lambda = 0.05 \times 10=0.5$

We are supposed to find What is the probability that there are no flaws in a given car’s interior i.e,P(X=0)

Substitute the value in the formula

$P(X=0)=\frac{e^{-0.5} \times (0.5)^0x}{0 !}$

$P(X=0)=\frac{e^{-0.5} \times (0.5)^0}{1}$

$P(X=0)=0.6065$

Hence the probability that there are no flaws in a given car’s interior is 0.6065
