Answer:
10.5??
Step-by-step explanation:
Draw a diagram to illustrate problem as shown below.
Let h = the height of the tree.
Because ΔABC ~ ΔADE, therefore
DE/BC = AD/AB
That is,
h/1.94 = (5.1 + 10.2)/5.1 = 3
h = 1.94*3 = 5.82 m
Answer: 5.82 m
STEP-BY-STEP SOLUTION:
To solve this equation, first make ( h ) the subject and then simplify as much as possible as displayed below:
2 ( h - 8 ) - h = h - 16
2h - 16 - h = h - 16
2h - h - h = - 16 + 15
h = 0

Answer:
Option D) $275
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $235
Standard Deviation, σ = $20
We are given that the distribution of amount of money spent by students is a bell shaped distribution that is a normal distribution.
Formula:

We have to find the value of x such that the probability is 0.975
Calculation the value from standard normal z table, we have,

Approximately 97.5% of the students spent below $275 on textbook.
