you want to determine how many students consider math to be their favorite subject. you randomly survey 75 students. 33 students consider math their favorite subject and 42 do not. you conclude 40% of students at your school consider math to be their favorite subject. Is that valid?
Answers
33 is 44% of 75
33 ÷ 75 = 0.44
0.44 = 44%

Answer:
A. Cylinder.
C. Cone.
Step-by-step explanation:
Notice that the cross section is parallel to the base. So, if the cross section is a circle, then the base is also a circle.
Then, we just need to find all figures that have a circle at the bottom. The figures are a cylinder and a cone.
Therefore, the right answers are A and C.
Answer:
A. Cylinder
C. Cone
Step-by-step explanation:
Both a cylinder and a cone are three dimensional shapes that contain a circle as the base. If a cross section is made parallel to the base, that means that it should have the same shape as the base. Since a pyramid and cube both have straight edges, it would not be possible to form a circle from a parallel cut to the base, so the only options are cylinder and cone.

What is an arithmetic operation?
The four fundamental operations of arithmetic are addition, subtracting, multiplying, and dividing two or more numbers. Included is the study of integers, especially the order of operations, which is essential for all other aspects of mathematics, notably algebra, information management, and geometry.
As per the data given in the question,
7.2 × 4= $28.8
$28.8 - 10=18.8
which means that she saves $18.8 per week.
18.8 × 12 = 225.6
She has collected 225.6 dollars over 12 weeks.
225.6 × 0.25 = 56.4
she received $56.4 from her grandparents,
$56.4 + $225.6 = $282
she has $282.
To know more about arithmetic operations:
#SPJ2
she saves 18.8 dollars per week.
18.8 times 12=225.6
after 12 weeks she has saved 225.6 dollars
225.6 times 0.25=56.4
her grandparents giver her 56.4 dollars
56.4+225.6=282
she has 282 dollars

Step-by-step explanation:
Yes bill is correct because both numbers are easy to add without regrouping, since when each of the digit are added there won't be carried over. Also, I believe Bill should be able to do simple mathematics like 2+3, 3+5 and so on.
Then, he should be able to add 3 plus 0 in his head and keep the result as 3. And then add the other 2+4 and he will put the two result together as 63
3+0 you don't have to regroup
And 4+2 you don't have to regroup
hope this helps

Distribute
(3/4)(4c)+(3/4)(16)=2c/9
3c+12=2/9 c
Now subtract 2/9 c from both sides
3c+12-2/9 c=2/9 c-2/9 c
25/9 c+12 =0
Now we need to subtract 12 from both sides
25/9 c+12-12=0-12
25/9 c=-12
Just multiply both sides by 9/25 so we find the value for c
25/9 *(25/9 c)=-12(9/25)
c= -108/25
I hope that's help:0

Step-by-step explanation:
a. b+2 (b+2b)
b. 3b+b
c. 2(2b)
Answers
Answer:
They are b and c.
Step-by-step explanation:
Let's simplify each expression:
a. b+2 (b+2b)
= b + 2b + 4b = 7b.
b. 3b + b = 4b.
c. 2(2b) = 2 * 2b = 4b.
Answer:
hello :
expressions are equivalent to 4b :
b ) 3b +b = 4b
c) 2(2b) = 4b
but : a) is not equivalent to 4b
because : b+2 (b+2b) = b + 2b +4b = 7b
