Wyatt's class:
Each group of 3 students eats 1 1/2 pizzas.
There are 18 students.
18/3 = 6
There are 6 groups of 3 students.
Since each group of 3 students eats 1 1/2 pizzas, 6 groups eat
6 * 1 1/2 = 6 * 3/2 = 18/2 = 9
Answer: 9 pizzas
Jennifer's class:
There are 15 students. Each student eats 1/3 of a pizza.
15 * 1/3 = 15/3 = 5
Answer: 5 pizzas

What is the are of parallelogram ABDC?
Answer:
9 cm2
Step-by-step explanation:
area=3×3=9cm2
.....
Answer:
9 cm^2
Step-by-step explanation:
inside the parallelogram, two right angled triangles form.
Use the formula, A = [tex]\frac{1}{2}[/tex] x base x height (Area of a triangle) and multiply by 2 as there are two triangles. So,
A = ([tex]\frac{1}{2}[/tex] x base x height) x 2
= ([tex]\frac{1}{2}[/tex] x 3 x 3 ) x 2
= 9 cm^2
(1 point) A recent report for a regional airline reported that the mean number of hours of flying time for its pilots is 56 hours per month. This mean was based on actual flying times for a sample of 51 pilots and the sample standard deviation was 9.5 hours.2. Calculate a 90% confidence interval estimate of the population mean flying time for the pilots. Round your result to 4 decimal places.( , )3.Using the information given, what is the smallest sample size necessary to estimate the mean flying time with a margin of error of 1.25 hour and 90% confidence
Answer:
(53.812 ; 58.188) ; 156
Step-by-step explanation:
Given that :
Sample size (n) = 51
Mean (m) = 56
Standard deviation (σ) = 9.5
α = 90%
Using the relation :
Confidence interval = mean ± Error
Error = Zcritical * (standard deviation / sqrt (n))
Zcritical at 90% = 1.645
Error = 1.645 * (9.5 / sqrt(51))
Error = 1.645 * 1.3302660
Error = 2.1882877
Hence,
Confidence interval :
Lower boundary = 56 - 2.1882877 = 53.8117123
Upper boundary = 56 + 2.1882877 = 58.1882877
Confidence interval = (53.812 ; 58.188)
2.)
Margin of Error (ME) = 1.25
α = 90%
Sample size = ((Zcritical * σ) / ME)^2
Zcritical at 90% = 1.645
Sample size = ((1.645 * 9.5) / 1.25)^2
Sample size = (15.6275 / 1.25)^2
Sample size = 12.502^2 = 156.3000
Sample size = 156

TARGET SELLS 24 BOTTELS OF WATER FOR 3 DOLARS AND 36 DOLARS WHICH IS THE BETTER BUY AND BY HOW MUCH
Answer:
The 36-pack is a better buy by $0.50 per 36 bottles.
Step-by-step explanation:
24 bottles for $3 compared to 36 bottles for $4
Unit rates:
$3/24 = $0.125/bottle
$4/36 = $0.111/bottle
The 36-pack is a better buy since the unit price is lower.
$0.125 - $0.111 = $0.013888...
$0.01388888... * 36 = $0.50
Answer: The 36-pack is a better buy by $0.50 per 36 bottles.
why can you use fraction multiplication to check the answer to a fraction division problem? How do you use multiplication to check a division problem
Answer:
Division and multiplication are inverse operations. This means they "undo" each other. You can check your answer by multiplying the quotient by the divisor. You should get the dividend.

Using two normal number cubes, what is the probability of rolling numbers
that add up to 4?
A. 1/18
B. 1/36
C. 1/12
D. 1/9
Answer:
1/12
Step-by-step explanation:
When we roll 2 dice, there are 36 possible rolls
How can we get 4
1and 3, 3 and 1, 2 and2 = 3 different rolls
P( 4) = number of rolls with sum of 4/ total rolls
= 3/36 = 1/12

What is hcf of the polynomial
Answer:
the highest common factor of the polynomial is (x + 2) (x - 3)
Step-by-step explanation:
The computation of the highest common factor of the polynomial is as follows:
According to the question, the following equation is given
'[tex]x^2 - x - 6[/tex]
Now do the factorization
[tex]x^2 -3x + 2x - 6[/tex]
x(x - 3) +2 (x - 3)
(x + 2) (x - 3)
hence, the highest common factor of the polynomial is (x + 2) (x - 3)
The same is to be considered

Use the linear equations to answer the questi
y= -3
y= x+2
Which statement about the lines is true?
Answer: Though no choices of statements are shown, you can predict that x+2=-3, since both numbers are equal to y. (This isn't really an answer but I hope it'll at least help you in some way!)
-By subtracting 2 on both sides, you end up with x=-5. So in both equations, y is -3 and x is -5.
-The point where they intersect is (5,-3)
A city planner is considering adding a pedestrian crossing signal to a particular intersection. They know that on average 11.5 cars go through the intersection each minute. It takes an average person 10 seconds to walk across the intersection. Name the distribution appropriate to model the time to the next car crossing this intersection (in minutes). Use the proper notation, and include the value of the distribution parameter (s).
Answer:
The number of cars that go through the intersection each minute X has Poisson distribution with parameter λ = 11.5
and the PMF of X is;
P (X = x) = e^-λ ( λˣ / x! ); where x = 0, 1, 2, 3, , , , , ,
Step-by-step explanation:
Given that;
on average eleven and a half cars go through the intersection each minute and It takes an average person ten seconds to walk across the intersection.
Therefore
The number of cars that go through the intersection each minute X has Poisson distribution with parameter λ = 11.5
and the PMF of X is;
P ( X = x ) = e^-λ ( λˣ / x! ) ;
where x = 0, 1, 2, 3, , , , , ,

Step-by-step explanation:
a line passeses through the ponts (2, a) and (4a,5) and has a slope of 1/2 find the value of a
Answer:
a=2
Step-by-step explanation:
Slope is found by (y2-y1)/(x2-x1)
Using the points, that is (5-a)/(4a-2) = 1/2
multiply both sides by the denominator 4a-2
5-a = (1/2)(4a-2)
5-a=2a-1
put like terms on opposite sides by adding a to both sides so a terms on the right, adding 1 on both sides so numbers are on the left
6=3a
divide both sides by 3
a=2
