Answer:
No it is wrong
Step-by-step explanation:
let's say the number is 15 is a substract 13 I get 2 but let's take 15 again of I add one I have 16 so it's incorrect
The graph of the function is a parabola.
The nose comes down as far as y=4 but no farther.
That happens when (x - 2)² = 0 , and THAT happens when x = 2 .
Answer:
A) 99.7% of people have an IQ between 64 and 136.
B) 5% of people have an IQ score less than 76 or greater than 124.
C) 16% of people have an IQ score greater than 112.
Step-by-step explanation:
The Empirical Rule tells us that, in a normal or 'bell-shaped' distribution, 68% of the data is one standard deviation from the mean, 95% of the data is two standard deviations from the mean, and 99.7% of the data is three standard deviations from the mean.
A) 64 and 136 are 3 standard deviations away from the mean, so 99.7% of people have an IQ between 64 and 136.
B) 76 and 124 are 2 standard devations away from the mean, but the answer is asking what percentage is not between them. 100% - 95% gives us 5%.
C) 112 is one standard deviation away from the mean. If we want to find the percentage greater, then we can do 100% - 50% (as 112 is to the left of the mean), then we can take half of 68 to get 34%, and after subtracting 50% and 34% from the 100%, we get 16%.
Twelve hundred times three equals 3600 so in 3 years it will cost 3600

Step-by-step explanation:
Hello
Match the points on the number line with the rational numbers.
a __ -6/8 = -(2 x 3)/(2 x 4) = -3/4
b __ -2/8 = -2/(2 x 4) = -1/4
c __ -4/8 = -4/(4 x 2) = -1/2
d __ 8/8 = 1
e __ 13/8
