Answer:
For the answer to the question above, the numbers of pages in the books in a library follow a normal distribution. If the mean number of pages is 180 and the standard deviation is 30 pages, you can conclude that about 16% of the books have fewer than 150 pages.
Are you looking for the value of x?
We can complete the square/factor:
x^2+7x-30=0
(x+10)(x-3)=0
By the zero product property rule, we have two equations, x+10=0 and x-3=0.
So the zeroes of x are -10 and 3
Hope this helped. Comment below if this didn't make sense.
Answer:
Answer is 46.50
Step-by-step explanation:
I look everywhere and said it was this hehe
A.) 155
123 + 47 + 35 = 205
Subtract 205 with 360 (360 is the measure of a circle) and you will be left with 155°.
