Answer: 0.86 of the exam scores are between 68 and 77.99 points
Step-by-step explanation:
Since the set of computer science exam scores are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = computer science exam scores .
µ = mean score
σ = standard deviation
From the information given,
µ = 71.33 points
σ = 3 points
We want to find the proportion of the exam scores are between 68 and 77.99 points. It is expressed as
P(68 ≤ x ≤ 77.99)
For x = 68,
z = (68 - 71.33)/3 = - 1.11
Looking at the normal distribution table, the probability corresponding to the z score is 0.13
For x = 68,
z = (77.99 - 71.33)/3 = 2.22
Looking at the normal distribution table, the probability corresponding to the z score is 0.99
P(68 ≤ x ≤ 77.99) = 0.99 - 0.13 = 0.86
Answer and Step-by-step explanation:
It be more than 2 ounces and less than 1.5 ounces
The amount of plastic that is melted in 5.7 minutes is 1.71
To find this, you would use the point on the graph. Divide both of those numbers by 4.
(4, 1.2)
4/4 = 1.
1.2/4 = 0.3.
So, for every minute, 0.3 of an ounce of plastic is melted.
We then multiply 0.3 by 5.7 to get 1.71.

Answer:
Isosceles triangle has two equal sides and two congruent bases.
Step-by-step explanation:
Isosceles triangle has three sides out of which two are equal. It has two congruent sides. The angle opposite to base is vertex. The two sides of the triangle are congruent and the angles opposite to these sides are also congruent. It is a special type of triangle which is also called equilateral triangle.
