Answer is C
Explanation-
Here’s an easier way to add negative numbers. Unlike adding positive numbers and positive numbers together and getting a larger positive number, do the opposite of what the symbol is telling you.
For example:
-12 + 9 = -4
Instead of adding, I subtract 12 and 9 to get to 4 but the reasons the four is a negative is because any number from 0 to any higher value is always considered a negative.
Answer:
range=u ± 3.09 sd
Step-by-step explanation:
Given:
mean, u= 26.8 mpg
standard deviation, sd=72 mpg
% contained in interval = 99.8%
the interval for 99.8% of the values of a normal distribution is given by
mean ± 3.09 standard deviation= u ± 3.09 sd
=26.8 ± 3.09(72)
=26.8 ± 222.48
= 249.28 , -195.68
range=u ± 3.09 sd = 249.28 , -195.68 !
D have neither a cat nor a dog
f(x)=2x^2+0x-5
Find the vertex
0/4=0=x
Input x into the equation to find y or f(x)
0+0-5=f(x)
(0,-5) = Vertex
Now find a random x coordinate to input into the equation.
Let's do 4.
32+0-5=f(x)=27
It may not look like a parabola due to it being uneven.
