Answer: 15

Step-by-step explanation:

First step is to find the slope of the line given

y = -x - 2

y = mx + c where m is the slope of the line so the slope of the line is -1

If 2 lines are perpendicular to one another, the product of the slopes is -1 so the slope of the perpendicular line is -1/-1 = 1

y = 1x + c or y = x + c

As the line passes through the coordinate (-5,10), we can substitute the x and y value of the coordinates into the equation

10 = -5 + c

c = 15

So the equation of the line is y = x + 15

At the deli counter, Marisol orders 740 grams of ham, 520 grams of turkey, and half as much roast beef as ham. What is the total

Alenkasestr [34]

Answer:

1.63 Kilograms

Step-by-step explanation:

I started by finding out what the roast beef weighed. Then I added 740, 520, and 370 (what the roast beef weighs). I can work that way because they are all in grams. The total off all that equals 1630 grams. Then I converted that to kilograms. Which will end up giving you 1.63 kilograms.

Bill is playing a game of chance with the following payout. 30% of the time you will lose 20 dollars, 20% of the time you will l

Kamila [148]

Answer:

The expected value of playing the game is -$7.

Bill should not play this game.

Step-by-step explanation:

The probability distribution of gain and loss is as follows:

X P (X)

-$20 0.30

-$40 0.20

$50 0.10

$5 0.40

Total 1.00

The expected value of a probability distribution is given by:

$E(X)=\sum {X\times P(X)}$

Compute the expected value of playing the game of chance as follows:

$E(X)=\sum {X\times P(X)}$

$=(-\$20\times 0.30)+(-\$40\times 0.20)+(\$50\times 0.10)+($5\times 0.40)\\\\=-\$6-\$8+\$5+\$2\\\\=-\$7$

The expected value of playing the game is -$7.

The expected value of the game suggests that Bill will incur a loss of $7 if he plays.

So, it is safe not to play the game.

In a common log we have an unwritten base of 10. That is, filling in our equation correctly, we have $7.5= log_{10} x$ . Logs and exponential functions are opposites of one another, so we can rewrite that log as an exponential function, like this: $10 ^{7.5} =x$ . Doing that math on our calculators we get that x is 31622776.60
