There are 500 students in a school. Sara asked 100 of the students what their favorite lunch is. Out of the students surveyed 45 said pizza, 15 said burritos, 30 said hamburgers, and 10 said hot dogs. Based upon the results, how many students out of the whole school should want the items listed? (Round to the nearest whole number.) Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50 Pizza: 22500 Burritos: 7500 Hamburgers: 15000 Hot Dogs: 5000 Pizza: 125 Burritos: 125 Hamburgers: 125 Hot Dogs: 125 Pizza: 45 Burritos: 15 Hamburgers: 30 Hot Dogs: 10
Answers
Answer: Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50
Step-by-step explanation:
Since Sara asked 100 of the students for their favorite lunch but there are 500 students in a school, this means that the items listed will have to be multiplied by 5 (500/100) in order to get the number of students in the whole school that'll need the items listed. This will therefore be:
Pizza = 45 × 5 = 225
Burritos = 15 × 5 = 75
Hamburgers = 30 × 5 = 150
Hot dogs = 10 × 5 = 50
The correct option is A:
Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50

PLEASE SHOW WORK ILL MARK BRAINLIEST.
Answers
Answer:
a = 3 - (7/4)b
Step-by-step explanation:
Start by performing the indicated multiplication:
2a+3b=12-2(2b+a) => 2a+3b=12 - 4b - 2a
Next, combine like terms: 4a + 7b = 12
Isolate 4a by subtracting 7b from both sides:
4a = 12 - 7b
Finally, divide both sides by 4:
a = 3 - (7/4)b
Which expression can be used to represent the 9 more than the quotient of 14 and 2? (14 + 2) ÷ 9 14 ÷ 2 X 9 (14 X 2) + 9 (14 ÷ 2) + 9
Answers
Answer:
The expression that can be used to represent 9 more than the quotient of 14 and 2 is (14 ÷ 2) +9
Step-by-step explanation:
The statement 9 more than the quotient of 14 and 2 means
9 + the quotient of 14 and 2.
Now, for the quotient of 14 and 2
Recall that,
Dividend ÷ Divisor = Quotient.
Here, Dividend = 14 and the Divisor is 2
Hence, the quotient of 14 and 2 can be represented by 14 ÷ 2
∴ The statement 9 more than the quotient of 14 and 2 becomes
9 + (14 ÷ 2) OR (14 ÷ 2) +9
Hence, the expression that can be used to represent 9 more than the quotient of 14 and 2 is (14 ÷ 2) +9

These four numbers are plotted on a number line: -2/3, 5/8, -3/5, and -1/2. Which is the correct ordering on the number line from left to right?
A. -1/2, -3/5, 5/8, -2/3
B. -3/5, -2/3, -1/2, 5/8
C. -2/3, -3/5, -1/2, 5/8
D. -1/2, -3/5, -2/3, 5/8
Answers
Answer:
-2/3 ; - 3/5 ; - 1/2 ; 5/8
Step-by-step explanation:
Given that:
We could convert the numbers to decimal to obtain a better view of the values :
-2/3 = - 0.66666
5/8 = 0.625
-3/5 = - 0.6
-1 /2 = - 0.5
Negative values are always arranged first on left of a number line.
-0.66666 < - 0.6 < - 0.5 <0.625
Hence,
-2/3 ; - 3/5 ; - 1/2 ; 5/8

The times to pop a regular bag of microwave popcorn without burning it are Normally distributed with a mean time
of 140 seconds and a standard deviation of 20 seconds. The times to pop a mini bag of microwave popcorn
without burning it are Normally distributed with a mean time of 90 seconds and a standard deviation of 15
seconds. Suppose two independent random samples, 25 of each, are taken and the mean popping times are
calculated. Let R = the popping time of a randomly selected regular-sized bag and M = the popping time of a mini-
sized bag. Which of the following best describes the standard deviation of the sampling distribution of 5-7 ?
1 second
5 seconds
25 seconds
35 seconds
Answers
Answer:
3
Step-by-step explanation:
Approximately normal with mean of 140 seconds and standard deviation of 10 seconds.
What is Central Limit Theorem:?The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean.
here, we have,
Given,
In the question:
The times to pop a regular bag of microwave popcorn without burning it are Normally distributed with a mean time of 140 seconds and a standard deviation of 20 seconds. The times to pop a mini bag of microwave popcorn without burning it are Normally distributed with a mean time of 90 seconds and a standard deviation of 15 seconds.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 140, standard deviation of 20, sample of 4:
By the Central Limit Theorem, the distribution is approximately normal.
Mean is the same, of 140.
n = 4 , σ = 20, thus:
s = σ /√n
= 20/√4
= 10
Thus, the correct answer is:
Approximately normal with mean of 140 seconds and standard deviation of 10 seconds.

Adam's Printing Inc. has two types of printing presses: Model A and Model B. Model A can print 80 books per day and Model B can print 55 books per day. Altogether Adam has 9 printing presses. If he can print 670 books in a day, then how many of each press does he have?
Answers
Answer:
Solution given:
model A printers [a] prints=80books per day
model B printers [b] prints=55books per day
total no of printers =9
no of model A printers be x
and
no of model B printers be [9-x]
According to the question;
ax+(9-x)b=670 books
substituting value of a and b; we get
80x+(9-x)55=670
80x-55x+495=670
25x=670-495=175
x=[tex] \frac{175}{25} [/tex]=7

no of model A printers =x=7
no of model B printers =9-x=9-7=2

Brent runs around a football field ,14m long and 12m inside. How much metre does Brent need in two laps
Answers
Answer:
Distance cover by Brent in 2 Lap = 104 meter
Step-by-step explanation:
Given:
Length of football field = 14 m
Width of football field = 12 m
Find:
Distance cover by Brent in 2 Lap
Computation:
Distance cover by Brent in 2 Lap = 2 x Perimeter of rectangular field
Perimeter of rectangle = 2[l+b]
Perimeter of rectangular field = 2[14 + 12]
Perimeter of rectangular field = 2[26]
Perimeter of rectangular field = 52 m
Distance cover by Brent in 2 Lap = 2 x Perimeter of rectangular field
Distance cover by Brent in 2 Lap = 2 x 52
Distance cover by Brent in 2 Lap = 104 meter
