What is the difference between the percentage of the female students who preferred pizza and the percentage of the male students who preferred pizza?
Answer:
35%
What is a percentage?
A percentage is a way of representing how much of a whole is present. Like a decimal or a fraction, a percentage is another form of showing these ratios and portions.
Finding Necessary ValuesFrom the chart, we need to find how the total number of female students and the total number of male students.
Female
[tex]18+12=30[/tex]
Male
[tex]5+15=20[/tex]
Solve - Female Students with Pizza Preference
First, take the number of female students that prefer pizza and divide it by the total number of female students.
[tex]\displaystyle \frac{18}{30}[/tex]
[tex]\displaystyle \frac{3}{5}[/tex]
Convert the fraction into a decimal by using a calculator.
[tex]\displaystyle \frac{3}{5} = 0.6[/tex]
Then, convert the decimal to a percentage by multiplying by 100.
[tex]0.6\times100=60\%[/tex]
The percentage of female students who preferred pizza is 60%.
Solve - Male Students with Pizza PreferenceTake the number of male students that prefer pizza and divide it by the total number of male students.
[tex]\displaystyle \frac{5}{20}[/tex]
[tex]\displaystyle \frac{1}{4}[/tex]
Convert the fraction into a decimal by using a calculator.
[tex]\displaystyle \frac{1}{4}=0.25[/tex]
Then, convert the decimal into a percentage by multiplying by 100.
[tex]0.25\times100=25\%[/tex]
The percentage of male students who preferred pizza is 25%.
Solve - Find the DifferenceFinally, subtract the percentage of male students who preferred pizza from the percentage of female students who preferred pizza.
[tex]60\%-25\%=35\%[/tex]
The final answer is 35%.

Answer:
#1:
cos a = opp/hyp = cb/ca
tan a = opp/ajd = cb/ab
sin c = adj/hyp = ab/ca
cos c = opp/hyp = ab/ca
tan c = opp/adj = ab/cb
2: *i dont have the square root symbol*
sin 60 = 3/2
cos 60 = x/2
tan 60 = 3/x
sin 30 = x/2
cos 30 = 3/2
tan 30 = x/3
3: *i dont have the square root symbol*
sin 45 = 2/x
cos 45 = x/2
tan 45 or 48 = x/y

Question 4
What is f(-5) for the function f?
f (x) =
9(x-11)
4
90x="
answer: [x]
Answer:
-36
Step-by-step explanation:
replace x with -5 and solve for the parenthesis and then take that number which would be -16 and multiply it by 9 which then would give you -144. So then you would take -144 and divide it by 4 and your answer would be -36.
Find the surface area of this rectangular prism.
a - 3 square units
b - 9 square units
c - 21 square units
d - 102 square units
Answer:
102 un²
Step-by-step explanation:
Area surface = 4( 3 x 7 ) + 2( 3 x 3 )
4( 21 )+ 2( 9 ) =

A doctor compiles a numbered list of all his 350 patients. He selects every 25th patient to receive a survey after
choosing to randomly start with the seventh name on the list. Which statement correctly identifies and justifies
whether the scenario represents an SRS?
O This represents an SRS because the sample was selected with a chance process.
O This represents an SRS because there were no restrictions placed on the sample group.
This does not represent an SRS because each individual chosen does not have an equally likely chance of being
chosen.
O This does not represent an SRS because each group of patients chosen does not have an equally likely chance
of being chosen.
Answer: This does not represent an SRS because each group of patients chosen does not have an equally likely chance of being chosen.
Answer:
the answer is D. This does no represent an SRS because each group of patients chosen does not have an equally likely chance of being chosen

Answer:
20
Step-by-step explanation:
First step is finding an angle in the rightmost triangle (angle K)
Using TOA we have
Tan(x)=4/8
x=26.565
which means that 90-26.565= 63.4349 will give us angle K in regards to the left triangle
Using this we can solve for JM
Tan(63.4349)=x/8
8tan(63.4349=x
x=16
So if JM = 16
and LM=4
take their sum to find JL
16+4=20
What are two numbers that multiple to -64 and add to -12
Answer:
-16,4 are the two numbers

Answer:
26
Step-by-step explanation:
The triangle equals 180 degrees the two measurements we already have is 90 degrees (the right angle) and 64 degrees.
90+64=154 and 180-154=26.
So 26 is your answer because 90+64+26=180

or, x= √50
or, x= √25×√2=5√2
Mahmoud is working out the height, h metres, of a tower
BT which stands on level ground.
He measures the angle TAB as 25°.
He cannot measure the distance AB and so he walks 80 m
from A to C, where angle ACB = 18° and angle ABC = 90°.
Calculate
Answer:
24.72 m
11.53 m
Step-by-step explanation:
Horizontal distance AB can be obtained from △ABC
From trigonometry :
Sin18° = opposite / hypotenus
Sin18° = AB / 80
AB = 0.3090169 * 80
AB = 24.72 m
The height BT, of tower from △ABT
From trigonometry :
Tan25° = opposite / Adjacent
Tan25° = h / 24.72m
h = Tan25 * 24.72
h = 11.527
h = 11.53 m
Hence, height of tower BT = 11.53 m

When Jamel went to the store, he spent $7 on 2.5 pounds of hamburger meat. What are two different ways to express the rate in this situation?
Answer:
a) [tex]0.357[/tex] pounds of hamburger meat can be purchased by spending 1 dollar
b) 1 pound of hamburger meat costs 2.8 dollars
Step-by-step explanation:
Rate in this case can be defined in two ways
a) The maximum amount of hamburger meat that can be purchased by spending 1 dollar
[tex]\frac{2.5}{7} \\= 0.357[/tex] pounds of hamburger meat can be purchased by spending 1 dollar
b) The maximum cost of 1 pound of hamburger meat
[tex]\frac{7}{2.5} \\2.8[/tex] dollar
Thus, 1 pound of hamburger meat costs 2.8 dollars

If the purchase price for a house is $309,900, what is the monthly payment if you put 20% down for a 30 year loan with a fixed rate of 6%? A. $729.98 b. $912.48 c. $1,486.41 d. $1,858.01 Please select the best answer from the choices provided A B C D
Answer:
The correct answer is A. $729.98.
Step-by-step explanation:
Given that the purchase price for a house is $ 309,900, to determine what is the monthly payment if you put 20% down for a 30 year loan with a fixed rate of 6%, the following calculation must be performed:
100 - 20 = 80
(309,900 x 0.80) x 1.06 / (30x12) = X
247,920 x 1.06 / 360 = X
262,795.2 / 360 = X
729.98 = X
Therefore, the monthly payments will be $ 729.98.
Answer:
Monthly Payment = 1,486.41
