Answer:
1.32t
Step-by-step explanation:
Raise 1.08 to the 4th power. (1.08 ^1/4)^4t=1.36t
The area of a triangle is A= 1/2bh. Plugging in the values you know, 30= 1/2*12*h.
Solving for h,
30= 1/2*12*h
30= 6h
h=5
The height of the triangle is 5 units.
A campsite is in the shape of a rectangle. The green region represents campsites with shade. The yellow region represents campsites without shade. The probability that your campsite has shade 1/2.
<h3>What is the probability?</h3>
Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
A campsite is in the shape of a rectangle.
The green region represents campsites with shade.
The yellow region represents campsites without shade.
There are only two possibilities either shaded or not shaded So, the total number of outcomes would be 2.
The probability that your campsite has shade = 1/2

Answer:
D. 68.00%
Step-by-step explanation:
Population mean time (μ) = 32 hours
Standard deviation (σ) = 2 hours
Assuming a normal distribution, for any given number of hours 'X', the z-score is determined by:
For X=30
For a z-score of -1, 'X' corresponds to the 15.87-th percentile of a normal distribution.
For X=34
For a z-score of 1, 'X' corresponds to the 84.13-th percentile of a normal distribution.
The percentage of the garages that take between 30 and 34 hours to erect is:
The percentage is roughly 68%.
