Imagine
at the top of the triangle and
at the bottom. (or used the attached picture for reference)
One thing to note, however, is that the side opposite
is the same side as the one adjacent to
! Thus
.
Substitute these values for
and
and solve.
Answer:
13.6 cm
Step-by-step explanation:
The slope of -0.6 tells you the change in height in 7 hours will be ...
(-0.6 cm/h) · (7 h) = -4.2 cm
This is added to the candle height after 12 hours, so the height after 19 hours is ...
17.8 cm -4.2 cm = 13.6 cm
Answer: 16
Step-by-step explanation:
Standard deviation is 2
Margin error for the problem is 1
Probability 95%, that means thet the siginficance level α is 1 – p
α = 1 – 0.95 = 0.05
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.05/2) = Z(0.025)
Using a z table Z = 1.96
Now, replacing in the equation and find n
1 = 1.96 * 2/ √n
1 = 3.92 / √n
√n = 3.92
n = 3.92^2
n = 15.36 = 16
i hope this work for you
HEY THERE:)
The expression you can use is 57 * 11 and it equals 627.
Hope this helps u!
good luck.
