A week = 7 days
6 inches = 7 days
x             = 24 days
cross multiply -> 6 x 24 divide by 7

7 days = 1 week/ 6 inches 21 days = 3 week ( 3 x 6 = 18 inches) + 3 days makes total of 24 days = 28 days make 4 weeks - 4 days short of 4 weeks. That means 21 inches in 24 days

There is a 70% chance that your car will get stuck in the snow during the next big snow fall. Given that you are already stuck i
nikdorinn [45]

Answer:

63%

Step-by-step explanation:

This is a problem of conditional probability.

The two events that are given are:

  • Car stuck in the snow - Let it be event S. P(S) = 70% = 0.70
  • Require a tow truck - Let it be event T.

We have to find the probability of being stuck in the snow AND requiring a tow truck which can be given as P(S and T)

We are also given the conditional probability, which is P(T | S) = 90% = 0.90

Using the given formula for our case we can modify the formula as:

P(T|S)=\frac{P(S \cap T)}{P(S)}

0.90=\frac{P(S \cap T)}{0.70}\\\\ P(S \cap T)=0.90 \times 0.70\\\\ P(S \cap T)=0.63

Therefore, there is 63% (0.63) chance that you will get stuck in the snow with your car AND require a tow truck to pull you out

Expression (5x² - 2x + 7), (\frac{1}{5}x^3 -\frac{7}{2}x^2 -2) and (y⁵ - √(5y²) + 7) are polynomials.

<h3>What is a polynomial ? </h3>

A polynomial is a type of algebraic expression where exponents of all variables are whole number.

1) 5x² - 2x + 7

Since there are no variables raised to negative or fraction exponents,

the expression is a polynomial.

2) \frac{1}{5}x^3 -\frac{7}{2}x^2 -2

Since there are no variables raised to negative or fraction exponents,

the expression is a polynomial.

3) y⁵ - √(5y²) + 7

This can be re-written as

y^5-(\sqrt{5})y+7

Since there are no variables raised to negative or fraction exponents,

the expression is a polynomial.

4) \frac{y^3}{3} -\sqrt{y} +2

This can be re-written as

\frac{1}{3}y^2 -y^{1/2}+2

Since variable y is raised to a fraction exponent,

the expression is not polynomial.

Therefore, expression (5x² - 2x + 7), (\frac{1}{5}x^3 -\frac{7}{2}x^2 -2) and (y⁵ - √(5y²) + 7) are polynomials.
