Some of the children at a school arrive by car.

scZoUnD [109]

Answer:

74%

Explanation:

You can build a two-way relative frequency table to represent the data:

These are the columns and rows:

Car No car Total

Boys

Girl

Total

Fill the table

30% of the children at the school are boys

Car No car Total

Boys 30%

Girl

Total

60% of the boys at the school arrive by car

That is 60% of 30% = 0.6 × 30% = 18%

Car No car Total

Boys 18% 30%

Girls

Total

By difference you can fill the cell of Boy and No car: 30% - 18% = 12%

Car No car Total

Boy 18% 12% 30%

Girl

Total

Also, you know that the grand total is 100%

Car No car Total

Boy 18% 12% 30%

Girl

Total 100%

By difference you fill the total of Girls: 100% - 30% = 70%

Car No car Total

Boy 18% 12% 30%

Girl 70%

Total 100%

80% of the girls at the school arrive by car

That is 80% of 70% = 0.8 × 70% = 56%

Car No car Total

Boy 18% 12% 30%

Girl 56% 70%

Total 100%

Now you can finish filling in the whole table calculating the differences:

Car No car Total

Boy 18% 12% 30%

Girl 56% 14% 70%

Total 74% 26% 100%

Having the table completed you can find any relevant probability.

The probability that a child chosen at random from the school arrives by car is the total of the column Car: 74%.

That is because that column represents the percent of boys and girls that that arrive by car: 18% of the boys, 56% of the girls, and 74% of all the the children.

Please Help? A circle has an arc length of 5π in. The central angle for this arc measures π/3 radians. What is the area of the a

Zielflug [23.3K]

Answer:

The area of the associated sector is $\frac{25}{24}\pi \ in^{2}$

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$C=5\pi\ in$

substitute and solve for r

$5\pi=2\pi r$

$r=2.5\ in$

step 2

Find the area of the circle

we know that

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=2.5\ in$

substitute

$A=\pi (2.5^{2})=6.25\pi\ in^{2}$

step 3

Find the area of the associated sector

we know that

$2\pi\ radians$ subtends the complete circle of area $6.25\pi\ in^{2}$

so

by proportion

Find the area of a sector with a central angle of $\pi/3\ radians$

$\frac{6.25\pi }{2\pi} =\frac{x}{\pi/3}\\x=6.25*(\pi/3)/2\\ \\x=\frac{25}{24}\pi \ in^{2}$
