Here is the answer (look at the photo)
Answer:
a) 1/10
b) 110
Step-by-step explanation:
A) we start by getting the total number of rolls
That would be;
11 + 22 + 7 + 8 + 13 + 19 = 80
The frequency of getting a 4 is 8
The probability that the next roll will be a 4 is;
8/80 = 1/10
b) Firstly, we get the probability of getting a 2
We have this as:
22/80
So for 400 rolls, the number of 2’s will be;
22/80 * 400
= 22 * 5 = 110
Answer:
The value of f(5) is:
-8
Step-by-step explanation:
Lets make table which represents the function.
Th table has 2 columns, first column contains values for x, second column contains values of y
The table has 4 rows, which means that there are 4 values of x, which corresponds to 4 values of y.
The table is given as:
x f(x)
-4 -2
-1 5
3 4
5 -8
We need to find the value of f(5).
We can get the value of f(5) if we substitute x = 5 into f(x)
We can see in the table, that if we substitute x=5 in f(x), we get the value of f(5) = -8
Which is the answer
Surface area of a cuboid
= [2(length)(width)] + [2(width)(height)] + [2(height)(length)]
= {[2(4)(2.5)] + [2(2.5)(2)] + [2(2)(4)]} units²
= (20 + 10 + 16) units²
= 46 units²
So to find an area of a square is length times width. 45 times 37 =1665inches now convert that to ft and that’s your answer!
Hope this helps!
