We know area of triangle =
In triangle ABC , AB is the base and BC is the height
Now we find the distance between A and B
Distance formula is
A(0,3), B(7,3)
Distance AB =
= = 7
B(7,3), C(7,7)
Distance BC =
= = 4
area of triangle =
area of triangle =
= = 14
Answer:
265 quarters ($66.25)
Step-by-step explanation:
10$ in quarters is 250 quarters.
you subtract the 15 from winning (=235), then add 50 for the jackpot (=285). Subtract another 20 for her final plays (=265).
we know that
The conjugate of a complex number is the number with equal real part and imaginary part equal in magnitude but opposite in sign
so
In this problem we have
the conjugate is equal to-------->
therefore
<u>the answer is the option</u>
10+3i
Answer:(a) margin error = 2.4%
(b) The margin error gives the measure in percentage of how the population parameter determined differ from the real population statistics or value.
(c) in 90% of the samples of teens in the country, the percent who go online several times a day will be within 50.6% and 55.4%. of the estimated 100%
Step-by-step explanation:
Using the proportion formulae
Margin error = z √p(1-p)/n
n= 1170, p = 53% = 0.53, 1-p = 0.47
and the z value at 90% C.I = 1.645
M error= 1.645 √0.53×0.47/1170
Margin error = 0.024 = 0.024 ×100
Margin error = 2.4%
53 - 2.4 = 50.6% and 53 + 2.4 = 55.4%
In other words 90% of the time: the number of teens who go online several time a day will be between 50.6 and 55.4%.
