She needs to read 20 more minutes.
10x4=40
60-40=20
Answer:
The value of x is 11 degrees
Step-by-step explanation:
Here, given that two angles are vertical angles, we are interested in calculating the value of x. We simply want to use an important property of vertical angles to get the value of x as given in the question.
When we talk of vertical angles, they are angles which lies on opposite side to each other when we have two intersecting line.
By property, vertically opposite angles are equal.
Thus, in this case, we are to equate the angles we are having since they are both vertical angles;
Thus,
Mathematically;
angle A = angle B
3x + 3 = 4x -8
Collect like terms;
4x-3x = 3 + 8
x = 11 degrees
Answer:
it would be -4 degrees F
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let X be length of life of the participants in the plan.
Given that X is N(68,3.5)
We convert this to standard normal score z using

a) proportion of the plan recipients that would receive payments beyond age 75=
b) proportion of the plan recipients die before they reach the standard retirement age of 65=
c) x for 86% ceased
