F(x) = 2x2 – 15<br> Find f(-2)

bogdanovich [222]

Wherever you see an x, replace it with -2,
So f(-2) = 2(-2^2) -15
= (2x4)-15
= -7

Which expression is equivalent to 4 sqrt 16x^11y^8/ 81x^7y^6 Assume x> 0 and y=0

Romashka [77]

One interpretation of your intent would be as follows:

16x^11y^8

Find 4 √ [-----------------]. Is that what you meant?

81x^7y^6

4*x^5*√x*y^4

If so, then the correct result would be 4 ---------------------

9*x^3*√x*y^3

and this could be reduced to:

4*x^5 * y^4 * √(x) 4*x^2*y

4 --------------------------- = -------------

9*x^3*y^3 √(x) 9

The grades on a language midterm at Oak Academy are roughly symmetric with = 67 and 0 = 2.5. Ishaan scored 70 on the exam. Find

rodikova [14]

Answer: 1.2

Step-by-step explanation:

Let X denotes the grades on a language midterm at Oak Academy.

As per given ,

X follows normal distribution ( because it has symmetric graph)

$\mu=67,\ \ \ \ \sigma= 2.5$

Formula for z : $z=\dfrac{X-\mu}{\sigma}$

For X = 70, we have

$z=\dfrac{70-67}{2.5}=\dfrac{3}{2.5}=1.2$

Hence, the z-score for Ishaan's exam grade = 1.2
