Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
Student being a boy.
8 boys from Wilmette
5 boys from Glencoe
3 boys from Winnetka
So
Total outcomes:
All students
Probability:
43.24% probability that the student will be a boy
Answer:
Step-by-step explanation:
<u>BOYS</u>
- 8 boys from Wilmette
- 5 boys from Glencoe
- 3 boys from Winnetka
<u>GIRLS</u>
- 4 girls from Winnetka
- 10 girls from Wilmette
- 7 girls from Glencoe
Total Number of Boys n(B)= 8+5+3=16
Total Number of Girls, n(G)=4+10+7 =21
Total Number of students, n(S) =21+16 =37

Using two unit multiplier 628 km is equal to 62800000 cm
<u>Solution:</u>
628 kilometer to centimeter
We will go from kilometers to meters to centimeters.
Start by putting 628 km over 1:
We want to get rid of km and bring in m.
We know that 1000 m = 1 km.
Since km is in the numerator, we will make the first unit multiplier by putting 1 km in the denominator and 1000 m in the numerator, so the km will cancel. So we multiply by the unit multiplier,
Now the km's will cancel:
Now we want to get rid of m and bring in cm.
We know that 100 cm = 1 m.
Since meter is in the numerator, we will make the first unit multiplier by putting 1 meter in the denominator and 100 cm in the numerator, so the meter's will cancel. So we multiply by the unit multiplier
We cancel the m's and we end up with:
= 62800000 cm
Thus 628 km is equal to 62800000 cm

<em>2 Bedroom</em>
The area is equal to
<em>3 Bedroom</em>
The area is equal to
The total area is equal to
A=A1+A2+A3
Approximate one gallon of paint covers 250 square feet
