Answer:
24
Step-by-step explanation:
The range of a data set is the difference between the largest value and the smallest value.
{98 76 100 88 82}
The lowest grade is a 76 and the highest grade is a 100.
100-76=24
The range of the test scores should be 24.
Answer:
13/15
Step-by-step explanation:
2/3 + 1/5
You first,
- Find the L. C. M, i hope u know the full name, if u don't, let me know in the comment section.
- the L. C. M is 15
- therefore it will be 10+3/15
- 13/15
Answer:
1/4a+3/4b
Step-by-step explanation:
OP=OA+AP
OA=a
AP=3/4AB
AB=-a+b
thus AP=3/4(-a+b) which is-3/4a+3/4b
OP=a-3/4a+3/4b thus 1/4a+3/4b
Answer:
6
Step-by-step explanation:
2904 = 2 x 2 x 2 x 3 x 11 x 11 = (2 x 3) x (2 x 2) x (11 x 11)
=> Smallest number by which 2904 must be divided so that it becomes a perfect number MUST belong to
{(2 x 3), (2 x 3) x (2 x 2), (2 x 3) x (2 x 2) x (11 x 11)} = {6, 24, 2904}
It is easy to see that the solution is 6
(this is the smallest number in collection above)
Answer:
Solving the equation by completing the square method we get
Option B is correct option.
Step-by-step explanation:
We need to solve the equation by completing the square method.
For completing the square method: we need to follow:
We are given:
Solving by completing the square
We need to find ? in our case ? is 3 because 2*3= 6 and our middle term is 6x i,e 2(x)(3)=6x.
So, adding and subtracting (3)^2
So, solving the equation by completing the square method we get
Option B is correct option.
