Answer:
The required number is 63
Step-by-step explanation :
Let the number be x
Now As per question , the equation is written as
x - 23 = 2 × [ 15 - ( - 3) ] + 4
Or, x - 23 = 2 × ( 18) + 4
Or , x - 23 = 36 +4
Or, x - 23 = 40
So, x = 40 + 23
∴ x = 63
Hence the required number is 63 Answer
Answer:
a) 1/5
Step-by-step explanation:
There are 25 students total in the class.
If you look at the Venn Diagram, you can see that only 5 people have only "Fb" accounts.
Therefore, the probability that the person has a “Fb” account but not a “Snap” account is 5/25 or 1/5.
Answer:
(^6√x^5) (√y)
(The 6 belongs in the left on top of the square root btw)
For x the 6 moves to the front of the square root while the 5 becomes the power of x.
For y, the power to the 1/2 is the same as a square root.

The larger the sample size (number of people asked), the more accurate the results generally are, due to the law of large numbers.
Answer:
312π mm^2
Step-by-step explanation:
to find the volume of the figure, you have to calculate the volume of a cone and the volume of a sphere divided it by 2.
The volume of a cone is 1/3 * π * r ^ 2 * h, replacing the information:
V = 1/3 * (6) ^ 2 * (14) = 168π mm^2
The volume of a sphere is 4/3 * π * r ^ 3, replacing the information:
V = 4/3 * π * (6) ^ 3 = 288π mm^2
but since you only have half the sphere
V = 288π / 2 = 144π mm^2
then the total volume is
Vt = 168π + 144π = 312π mm^2
