Hi there!
<u>1) Find the length of the other leg in the right triangle</u>
There are two ways we can go about this. The first way is to use trigonomic ratios:
We're given one of the legs and we're trying to solve for the other, so we can use the tangent ratio:
Let x be equal to the length of the other leg. Plug in the known values:
The other way to find this is to observe the angles. Because we're given that two of the angles are 45 and 90 degrees, we know that the third angle is 45 degrees. This makes this an isosceles triangle, meaning the other leg is 7 ft long.
<u>2) Determine the height of the hoop</u>
Add 7 ft and 5 ft (the person's height):
7+5=12 ft
I hope this helps!
Answer:
probability of 1st defective = 0.844
correct option is d. 0.844
Step-by-step explanation:
given data
probability defective = 0.17%
undefective microscopes = 100
to find out
the probability that the first defective microscope
solution
we know defective probability P = 0.17% = 0.0017
so non defective probability (1-P) = 1 - 0.0017
non defective probability (1-P) = 0.9983
and
1st defective come after 100 it mean 1st 100 are non defective so
probability of 1st defective =
probability of 1st defective =
probability of 1st defective = 0.844
so correct option is d. 0.844
