Answer:

2/5

Step-by-step explanation:

P(drive to school) = number of students that drive to school ÷ total number of students

P(drive to school) = 40/100

P(drive to school) = 2/5

Answer:

<u>The probability would be:</u>

<em>(number of students drive to school)/(total number of selected students)</em>

  • The number of students who drive to school can be calculated as 2+13+25=40
  • The total number of students is stated as 100.

<u>Therefore, the probability would be:</u>

\frac{40}{100}=\frac{4}{10}  =\frac{2}{5}

The function for the total cost will be given as h(x)  =  5.94x  +  2.25.

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

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

Given that:-

  • The function f(x) = 4.95x represents the cost to purchase x pounds of chocolate from a candy company
  • The function g(x) = 0.99x + 2.25 models the cost to ship x pounds of chocolate from the company.

The function h(x) for total cost will be calculated as:-

h ( x )  =  4.95x   +   0.99x  +   2.25

h ( x )  =  5.94x   +   2.25

Therefore the function for the total cost will be given as h(x)  =  5.94x  +  2.25.

Your friend, Jamie, rolled a number cube and got the number 5. On his next turn, he says he won’t be able to roll another 5 beca
olga nikolaevna [1]

Answer with explanation:

When a Number cube numbered from 1 to 6 is rolled once,

total possible outcome ={1,2,3,4,5,6}

Probability of each outcome that is ,

P(1)=P(2)=P(3)=P(4)=P(5)=P(6)=\frac{\text{total favorable outcome}}{\text{Total possible outcome}}=\frac{1}{6}

→So, each outcome has equal chance when a die is rolled 6 times.But in actual ,that is in experimental probability this seems impossible.

→When you are dealing with theoretical probability,we state that ,yes when a number cube is rolled six times each outcome has equal chance of coming.

→No, my friend is Incorrect,because here he is performing experiment in real life,there are chances that in next five trials ,number 5 only appears on the number cube,but  when number of rolling of number cube becomes very high and higher, then probability of occurring of each number becomes same.

Solve the equation x = 5/3 (pie) (r^3) for r.
DENIUS [597]

Answer and Step-by-step explanation:

To solve for r, we need to get everything away from r. We can start off by moving five thirds, and pi.

x = \frac{5}{3} \pi r^{3}

Multiply each side by \frac{3}{5}, then divide by \pi (pi)

\frac{3x}{5\pi }  = r^{3}

Now, take the cubed root of both sides.

\sqrt[3]{\frac{3x}{5\pi } }  = r

^^ That is the answer.
