Answer:
alright so basically solve and find each value out of exponent so it would be 16-8 over 32-16 which is 8/16 which simplifies to 1/2 which is ur answer
<h3>
Answer: 34% (approximate)</h3>
=================================================
Explanation:
We have 7 at the center. Going 2 units to the left of center gets us to 7-2 = 5. Going 2 units to the right of center gets us to 7+2 = 9.
Since the mean is 7 and the standard deviation is 2, this tells us that the values 5 and 9 are exactly one standard deviation away from the mean.
Due to the empirical rule (aka 68-95-99.7 rule), we just found that roughly 68% of the population is between 5 and 9.
Half of this is 68/2 = 34%, so this is the percent of values between 7 and 9.
Answer:
1.5
Step-by-step explanation:
the slope formula is y2-y1/x2-x1
so take two given points (I'll use (-1, -5) and (3,1))
1--5/3--1
6/4
1 2/4

let calculator do the rest and then ur done
Answer:
100㏑²
Step-by-step explanation;
first of all you find the base using the pythagoras theorem
that is, √13² - 12² =√25 = 5
so 5 is the base of the right angle in the big isoceles triangle
so the base of the isoceles triangle is 10 [5 + 5]
so for the first triangle the area is 60㏑²
the second triangle is 40㏑²
therefore 60 + 40 = 100㏑²
