Answer:
<em>Sherita would need to make 10 free throws</em>
Step-by-step explanation:
<u>Proportions</u>
Sherita made 46 of her first 60 free throws in this basketball season. Calculating the average we get:
Sherita wants to have a free throw average of at least 80% in her next x free throws. This means she will have 46+x made throws out of 60+x total throws. For this new performance, the new average would be:
And we equate it to 80% (0.8 in decimal):
Multiplying by 60+x:
Operating:
Subtracting 46 and 0.8x:
0.2x=2
Dividing by 0.2
x = 10
Sherita would need to make 10 free throws
The solution to this problem is (-2,0). Your welcome, and yes im positive this is the correct answer.
We first determine the z-scores for the given x-values of 64 and 96.
For x = 64: z = (64 - 80) / 8 = -2
For x = 96: z = (96 - 80) / 8 = 2
Therefore we find the probability that -2 < z < 2, which is around 0.95. Therefore, out of 100 students, approximately 100(0.95) = 95 students will weigh between 64 and 96 pounds.

Step-by-step explanation:
it has two sides that are the same length, but not all three sides are the same length
An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides equal
