When 18/x=-2 x’s value will be equal to -9
Answer: C) 50% of the students scored below 70%
<u>Step-by-step explanation:</u>
Mean is the average. To find the mean (aka average) you add up all of the scores and divide by the number of tests.
B) The mean can be 70 without any test scoring 70% so B is not true.
A) Since B is not true, then A is not a valid option.
D) We don't know any of the other data so don't know if it is skewed left, skewed right, or normal. Therefore, option D is not true.
C) If the average is 70%, then half received grades above that score and half received grades below that score. So, option C is TRUE!
with that template in mind.
![\bf f(x)=\sqrt[3]{x}\qquad \boxed{-f(x+2)+4}\implies f(x)=\stackrel{A}{-1}\sqrt[3]{\stackrel{B}{1}x\stackrel{C}{+2}}\stackrel{D}{+4}\qquad \\\\\\ f(x)=-\sqrt[3]{x+2}+4](https://tex.z-dn.net/?f=%5Cbf%20f%28x%29%3D%5Csqrt%5B3%5D%7Bx%7D%5Cqquad%20%5Cboxed%7B-f%28x%2B2%29%2B4%7D%5Cimplies%20f%28x%29%3D%5Cstackrel%7BA%7D%7B-1%7D%5Csqrt%5B3%5D%7B%5Cstackrel%7BB%7D%7B1%7Dx%5Cstackrel%7BC%7D%7B%2B2%7D%7D%5Cstackrel%7BD%7D%7B%2B4%7D%5Cqquad%20%0A%5C%5C%5C%5C%5C%5C%0Af%28x%29%3D-%5Csqrt%5B3%5D%7Bx%2B2%7D%2B4)
A = -1, reflected over the x-axis
B = 1, C = 2, horizontal shift of C/B or 2, to the left.
D = 4, shifted upwards by 4 units.
check the picture below.
It would be (6,9) from the given end point to the given middle point it is a 7 point difference, so we add 7 to the y value to get the other endpoint, hope it helps!
