Answer:
Part A)
Part B)
Part C)
Part D)
Step-by-step explanation:
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
Let
x------> size of the event space
y------> size of the sample space
P=x/y
Part A) What percent of all children are girls?
we have that
y= 360 children
x=198 girls
substitute
p = 198/360 0.55
Find the percentage
0.55*100=55%
Part B) What percent of all children are boys?
we have that
y=360
x=360-198
substitute
p= 162/360=0.45
Find the percentage
0.45*100=45%
Part C) The number of girls is what percent of the number of boys?
we have that
y=162
x=198
substitute
p=198/162=1.22
Find the percentage
1.22*100= 122%
Part D) The number of boys is what percent of the number of girls?
we have that
y=198 girls
x=162 boys
substitute
p=162/198=0.8182
Find the percentage
0.8182*100=81.82%
The percentage of the school are girls is 55%.
The percentage of the school are boys is 45%.
The number of boys in the school is 162.
The number of girls in the school is 198.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, In a school containing 360 children, 198 are girls.
Therefore, The percentage of the school are girls is,
(198/360)×100%.
= 55%.
The percentage of the school are boys is,
= [(360 - 198)/360]×100%.
= 45%.
Or The percentage of the school are boys is, (100 - 55)% = 45%.
The number of boys in the school is,
(360 - 198).
= 162 boys.
The number of girls in the school is 198.

L4 for f(x)=1/x−1; [2,3]
Answer:
[tex]L_4=0.7595[/tex]
Step-by-step explanation:
We are given that
[tex]f(x)=\frac{1}{x-1},[/tex][2,3]
We have to find L4
It means n=4
[tex]\Delta x=\frac{b-a}{n}=\frac{3-2}{4}=\frac{1}{4}=0.25[/tex]
Now, intervals are
[2,2.25],[2.25,2.50],[2.5,2.75],[2.75,3]
Now,
[tex]L_4=f(x_0)\Delta x+f(x_1)\Delta x+f(x_2)\Delta x+f(x_3)\Delta x[/tex]
[tex]L_4=\frac{1}{2-1}(0.25)+\frac{1}{2.25-1}(0.25)+\frac{1}{2.5-1}(0.25)+\frac{1}{2.75-1}(0.25)[/tex]

Answer:
Step-by-step explanation:
Gabriela's mass : Pierre's mass = 3 : 8
Gabriela's mass = 3x
Pierre's mass = 8x
Total mass= (1/4) of total height
3x + 8x = [tex]\frac{1}{4}(110 + 154)[/tex]
11x = [tex]\frac{1}{4}*264[/tex]
11x = 66
x = 66/11
x = 6
Gabriela's mass = 3x = 3*6 = 18 Kg
Pierre's mass = 8x = 8*6 = 48 kg
Solve for x.

The school show choir is holding a car wash to raise $350 for
new costumes. After spending $30 on supplies, the students will
wash cars for donations of $6 each.
This situation can be modelled by the inequality 6C + 30 > 350,
which has the solution c> 53.33. What is the best way to
interpret this solution?
A. Show choir needs $53.33 to meet their goal.
B. Show choir should have spent another $53.33 on supplies.
C. At least 54 show choir students must participate in the car
wash.
D. Show choir needs to wash at least 54 cars.
Answer:
D.
Step-by-step explanation:
It’s the only option that makes sense. Option A. Is invalid because they need to make $350. Option B. Is just purely invalid and has no context to support the theory. C. Is possible, but we can have students wash more than one car, so we don’t need fifty four kids.
D. Is your answer.

Answer:
angle 1 = 51
angle 2 = 34
angle 3 = 95
angle 4 = 38
angle 5 = 47
angle 6 = 74
angle 7 = 59
Step-by-step explanation:
a straight line is 180 degree, so to find angle 1, subtract 129 by 180.
angle 2 is found by adding angle 1 and 95 then subtract that by 180.
angle 3 and 95 are opposite angles, so they are the same
for angle 4, add angle three and 47 then subtract that by 180
angle 5 is 47, they are opposite
angle 7, subtract 121 by 180
angle 6, you add angle 5 and 7, and subtract that by 180
