Answer: A and E
Step-by-step explanation:
The 150 students in the band will attend an awards assembly. A random survey of 30 was done to see what type of pizza they would order. 10 Pepperoni 15 Cheese • 5 Hamburger Based on the survey results, which of these is the best prediction of the types of pizza wanted by the 150 students? A. There are 40 students who want pepperoni B. There are 100 students who want either pepperoni or hamburger C. There are 10 more students who will want cheese than hamburger D. There are 5 more students would want pepperoni than hamburger (PLEASE ANSWER ILL GIVE BRAINLIEST)
Answer:
None are correct.
Step-by-step explanation:
10/30 wanted pepperoni, so 1/3 of them wanted pepperoni.
15/30 wanted cheese, so 1/2 wanted cheese.
5/30 wanted hamburgers, so 1/6 wanted hamburgers.
You can use this information to estimate the number of the 150 students who wanted each.
1/3 of 150 = an estimated 50 wants pepperoni
1/2 of 150 = an estimated 75 wants cheese
1/6 of 150 = an estimated 25 wants hamburgers
Now you can use this to see which one is true.
A. There are 40 students who want pepperoni
not true, there are 50
B. There are 100 students who want either pepperoni or hamburger
50(pepperoni) + 25(hamburger) = 75, so this is not true
C. There are 10 more students who will want cheese than hamburger
75(cheese) - 25 (hamburger) = 50, so this is not true.
D. There are 5 more students would want pepperoni than hamburger
50 (pepperoni) - 25 (hamburger) = 25, so this is not true
None of these answers are correct

Find the mode of the following number of countries randomly selected travelers visited in the past two years. 13,13,15,7,8,4,4,7,13
Answer:
The mode of the following number of countries randomly selected travelers visited in the past two years is 13.
Step-by-step explanation:
The mode of a data-set is the value that appears the most commonly, the most frequently.
In this data-set:
13 appears 3 times
7 and 4 twice
The others once
So 13 is the mode.

Find the Area of the figure below, composed of a parallelogram and two semicircles. Round to the nearest tenths place.
Please help
See the picture
Test
Please i need
Answer:
100.3 units²
Step-by-step explanation:
Area of the figure = area of two semicircles + area of a parallelogram
= 2(½*πr²) + b*h
Where,
Radius (r) = ½ of 8 = 4
Base (b) = 10
Height (h) = 5
Plug in the values
Area of figure = 2(½*π*4²) + 10*5
= 16π + 50
Area = 100.265482
Area of figure = 100.3 units² (nearest tenth)

Step-by-step explanation:
-3x+10y=2
-3x+3y=9
-3x=2-10y
-3x=9-3y
2-10y=9-3y
2-9=10y-3y
7y=-7
y=-1
-3x+3(-1)=9
-3x-3=9
-3x=12
x=-4
Answer:
X=4, y=-1
Step-by-step explanation:
-3x+10y=2 multiple by 3
-3x+3y=9 multiply by 10
9x+30y=6
30x+30y=90
Subtract equation 1 from 2
30x-9x+30y-30y=90-6
21x+0=84
21x=84
Divide both side by 21
X=4
Substitute 4 for x in equation 1
3x+10y=2
3(4)+10y=2
12+10y=2
10y=2-12
10y=-10
Divide both side by 10

Answer:
(2^-14 * 5^10)
Step-by-step explanation:
(2^-7 * 5^5)^2
From.the law of indices :
(a^m)^n = a^mn
Such that we multiply both powers
Hence the equation, W will become :
2^(-7*2) * 5^(5*2) = (2^-14 * 5^10)
The diameter of Joseph's bicycle wheel is 20 inches Which is the circumference to the nearest inch?use 3.14 for Π
Answer:
63 inches
Step-by-step explanation:
the diameter is the entire line across the circle, the things needed to find out the circumference of the circle are the radius. that means you would divide your diameter in half to get 10. after you done that, you would input that into the equation:
c=2Π10
that would get you about 62.83 or 63

How do you find the area of a triangle ?
Answer:
to find the Area of a Triangle, you have to multiply the base times the height of the triangle to find the Area.
Step-by-step explanation:
For example..
If the Base ( bottom part of the triangle) was 10 and the height ( the vertical line of the triangle) was 5, you would multiply them together to get 50. So 5o would be the area of the Triangle.

Two dice are tossed and the magnitude of the difference in the number of dots facing up in the two dice is noted. (a) What is the sample space of the event of tossing of the two dice
Answer:
Sample space S = {0,1,2,3,4,5}
Step-by-step explanation:
We all know that when a dice is tossed, the minimum value that can be obtained is 1 and the maximum value that can be obtained is 6.
Now, when two dice are tossed, the possible cases are:
[tex]= \left\{\begin{array}{cccccc}(1,1)&(1,2)&(1,3) &(1,4)&(1,5)&(1,6)\\(2,1)&(2,2)&(2,3) &(2,4)&(2,5)&(2,6)\\(3,1)&(3,2)&(3,3) &(3,4)&(3,5)&(3,6)\\(4,1)&(4,2)&(4,3) &(4,4)&(4,5)&(4,6)\\(5,1)&(5,2)&(5,3) &(5,4)&(5,5)&(5,6)\\(6,1)&(6,2)&(6,3) &(6,4)&(6,5)&(6,6)\end{array}\right\}[/tex]
However, the magnitude of the difference in no. of dots showing up in the two dice is:
[tex]= = \left\{\begin{array}{cccccc}(1,1)=0&(1,2)=1&(1,3)=2 &(1,4)=3&(1,5)=4&(1,6)=5\\(2,1)=1&(2,2)=0&(2,3)=1 &(2,4)=2&(2,5)=3&(2,6)=4\\(3,1)=2&(3,2)=1&(3,3)=0 &(3,4)=1&(3,5)=2&(3,6)=3\\(4,1)=3&(4,2)=2&(4,3)=1 &(4,4)=0&(4,5)=1&(4,6)=2\\(5,1)=4&(5,2)=3&(5,3)=2 &(5,4)=1&(5,5)=0&(5,6)=1\\(6,1)=5&(6,2)=4&(6,3)=3 &(6,4)=2&(6,5)=4&(6,6)=0\end{array}\right\}[/tex]
Thus, the sample space Sample space-related when two dice are tossed & the magnitude is:
S = {0,1,2,3,4,5,}
