Answer:

(A) -7

Step-by-step explanation:

The function is continuous if you can draw its graph without lifting your pencil. In this case, that means each of the piecewise function definitions must have the same value at x=3.

x^2 +2 = 6x +k . . . . . must be true at x=3

3^2 +2 = 6(3) +k . . . . substitute 3 for x

9 +2 -18 = k . . . . . . . . subtract 18

k = -7 . . . . . . . simplify

if two dice are thrown together , what is the probability of getting an even number on one die and odd number on the other die ?

Veronika [31]

Answer:

1/2

Step-by-step explanation:

the probability of the die rolling an even number = the probability of the die rolling an odd number =1/2

Let us name these 2 dice as A and B

One die can roll an even and the other can roll an odd, in the following cases

A rolls even and B rolls odd. The probability of this happening =1/2×1/2

A rolls odd and B rolls even. The probability of this happening =1/2×1/2

∴ The required probability

=1/2×1/2+1/2×1/2

=1/4+1/4

=1/2

What is the weekly gross pay?

romanna [79]

You want to multiply 40 hours by the regular hourly pay which would be $9.14,
9.14*40= 365.6

Overtime is generally 1.5 times regular pay so take 9.14*1.5= 13.71 and this would be your overtime hourly rate

Regular hourly rate (1x) : $9.14
Overtime hourly rate (1.5x): $13.71

Take your 8 hours of OT and multiply it by 13.71
13.71*8= 109.68

Add 365.6 and 109.68 to get a final answer of 475.28. The answer would've been C
