Let us assume the number of free throws attempted this season = x
Number of free throws made = 93
Percentage of free throws made = 75%
Then
(75/100) * x = 93
3x/4 = 93
3x = 93 * 4
x = (93 * 4)/3
= 31 * 4
= 124
So the total number of free throws attempted is 124. I hope the procedure is clear enough for you to understand. You can always attempt similar type of problems on your own using the method described.
I tried to read this I only see the last set . So I can’t answer it I only see half of the question
Well first off those numbers add up to 163.
A way to check this is to add 52 with 23 which is 75 then add 78 by 10 which is 88 now add 75 with 88 which is 163
If you know how to use built-in statistical functions on a calculator such as the TI-83 or 84, you can solve this problem with one press of the ENTER key on the calculator:
normalcdf(-100, 400, 504, 111) = 0.17 (answer)
Otherwise, find the z-score associated with 400:
400-504
z= ------------- , and the use a z-score table to find the area under the
111 standard normal curve to the left of this z value.
Perfect squares are:
1,4,9,16,25,36,49,64,81,100,....
the sum of the digits of our biggest number is 16 so any perfect square bigger than 16 doesn't work for us
1-
1+0=1 so any number containing the digits will work(keep in mind we only will look into whole numbers because digits can't be negative or have fractions or be irrational)
thereful 10 works for our category
2-
0+4=4
1+3=4
2+2=4
22 13 31 and 40 will work two
3-
0+9
1+8
2+7
3+6
4+5
90 18 81 27 72 36 63 45 54
4-
0+16
1+15
2+14
3+13
4+12
5+11
6+10
7+9
8+8
79 97 88
so our set of numbers contain:
10 22 13 31 40 90 18 81 27 72 36 63 45 54 79 97 88
