Where you see an x in the expression replace it with -5

3(-5) - 9

Using the rules of PEMDAS simplify

-15 - 9

-24

Hope this helped!

Consider an experiment with a deck of 52 playing cards, in which there are 13 cards in each suit, two suits are black, and two s
lakkis [162]

Answer:

<u>P (E1) = 1/2 or 50%</u>

<u>P (E2) = 3/13 or 23%</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of playing cards = 52

Number of suits = 4

Number of cards per suit = 13

Number of black suits = 2

Number of red suits = 2

2.  Suppose E1 = the outcome is a red card and E2 = the outcome is a face card (K, Q, J). Determine P(E1 or E2).

P (E1) = Number of red cards/Total of playing cards

P (E1) = 26/52 = 1/2 = 50%

P (E2) = Number of face cards/Total of playing cards

P (E2) = 12/52 = 3/13 = 23%

use the graph of y=e^x to evaluate the expression e^0. round the solution to the nearest tenth if necessary​
Wittaler [7]

In the attached picture you have the graph of y=e^x. To evaluate the function at x=0, you'll have to start from 0 on the x axis, and travel vertically until you meet the graph.

In this case, if you start from the origin, you have to go upwards one unit, until you meet the graph at (0,1).

So, if x=0, y=1.

Answer:

30 minutes

Step-by-step explanation:

Think of it as a fractions. Player 1: 6 min./1 lap, Player 2: 10 min./1 lap. So in order to do this you have to find the greatest common factor. The GCF is 30. [learned this 2 yrs ago, im not entirely sure]
