Answer:

Probability of head and prime = 1/4 or 0.25

Step-by-step explanation:

Total number face in dice = 6

Face that is prime ( 2,3,5) = 3

Total number face in nickel = 2

Total number of head in nickel = 1

Probabilty of prime = 3/6

Probabilty of prime = 1/2

Probabilty of head = 1/2

Probability of head and prime

= 1/2 * 1/2

= 1/4

= 0.25

For this question, we use the Pythagorean theorem.

a^2+b^2=c^2

We know the lengths of the legs, a and b.
a=3
b=4

Now, let's solve for the hypotenuse, c.

3^2+4^2=c^2
25=c^2

Take the positive square root.

\boxed{c=5}

Hope this helps! :)

Find g(a - 1) when g(x) = 5x - 4.
pishuonlain [190]

Answer:

g(a-1) = 5a-9

Step-by-step explanation:

Hi there!

g(x) = 5x - 4

Replace all x's with a-1:

g(a-1) = 5(a-1) - 4\\g(a-1) = 5a-5 - 4\\g(a-1) = 5a-9

I hope this helps!

Hello!

First you to do 65 * 0.20

0.20 is 20% as a decimal

65 * 0.20 = 13

$13 is how much John saves.

To find out how much the skateboard cost you subtract how much he saved by the cost of the skateboard

65 - 13 = 52

The skateboard cost $52
