Answer:

b) 1.34

Step-by-step explanation:

The z score is used to determine the number of standard deviations by which the raw score is above or below the mean. If the z score is positive then the z score is above the mean while for a negative z score implies that it is below the mean. The z score is given by:

z=\frac{x-\mu}{\sigma}

For the largest 9%, the score is 100% - 9% = 91% = 0.91

From the normal distribution table, the z score that corresponds to 0.91 is 1.34

Find the derivative of g(y)=(y-4)*(2y+y^2)
sasho [114]

Answer:

g'(y)=3y^2-4y-8

Step-by-step explanation:

start by foiling out the given function

g(y)=(y-4)(2y+y^2)\\=2y^2+y^3-8y-4y^2\\=y^3-2y^2-8y

next, use the power rule to find the derivative

power rule: To use the power rule, multiply the variable's exponent n, by its coefficient a, then subtract 1 from the exponent. If there's no coefficient (the coefficient is 1), then the exponent will become the new coefficient.

g'(y)=3y^2-4y-8

Kevin bought a membership to a golf club. He pays $250 per month and $18 every time he plays a round of golf. Write an equation
Arturiano [62]
Hi there!

Let's solve this problem step by step!

The cost of 1 round of golf is $18
and therefore the total cost for all of the tickets is $18 × 
the amount of golf plays, mathematically $18 × g, hence 18g

The membership cost of 1 month is $250
and therefore the total cost for all of the tickets is $250 × 
the amount of months, mathematically $250 × m, hence 250m.

Now we can set up the equation. The only thing we need to do is adding up the individual functions.

Answer:
C = 250m + 18g
