Out of 6, the chance for a 1 or a 5 is 2. Probability is the something is the number of desired outcomes over the number of all possible outcomes. Therefore the probability is 2/6 to roll a 1 or a 5. From here, we need to find how much 2/6 of 100 is.
2/6 = x/100
200/6 = x
33.3 = x
Since its impossible to roll part of a dice, we'll round to a whole number. 33.3 rounds to 33, therefore he will roll a 1 or a 5 33 times.

Answer:
Here are my answers
hope this helps
Step-by-step explanation:
1. isosceles triangle
2. 3x + 15 = 90 x = 25
x + 25 = 90 x = 65
x + 55 = 90 x = 35
3. The size for DAB is 84
My reasoning is I went from one angle to another by subtracting 180 from my answers. For example angle 132 is supplementary to the missing angle next to it. I subtract 180 from 132 and get 48. That already solves the 2 equivalent angles in the triangle so I have 48+48+x = 180 because a full triangle equals 180. I get x = 84 then I do the same thing I did with angle 132. Angle 84 is supplementary to the missing angle next to it. I subtract 84 from 180 and get 96 then go diagonal from angle C (which is 96) to angle A. Those are supplementary so I subtract 96 from 180 and get 84.
Answer:
16.373,16.4
Step-by-step explanation:
Given that a random sample of 11 university students produced the following data, where x is the minutes spent studying per day, and y is the first exam score (out of a maximum of 100 points).

We get regression line as y =2.369x+16.373
a) value of intercept = 16.373
b) 16.4
I know B is on possible choice for this and maybe d almost certain
