PLEASE ANSWER ASAP!!! FULL ANSWERS ONLY!!!!!! WILL GIVE BRAINLIEST!!!!!!!!!Dakota's wife sends him to the store to buy pickles and ice cream. Ice cream cost 5 dollars per pound and pickles costs 4 dollars per pound. Dakota has 100 dollars in his wallet.

Let x be the number of pounds of ice cream and y be the number of pounds of pickles that Dakota purchases. State the inequality that represents his budget, and graph the solution that represents the possible combinations of x and y. Express your answer with the standard form ax+by on the left side.

The budget inequality is _________________________

Answers

Answer 1
Answer:

Answer: 5x + 4y ≤ 100

Step-by-step explanation:

  • x = amount of ice cream($5 each)
  • y = amount of pickles($4 each)

5x + 4y ≤ 100

It has to be ≤ 100 because the dude only has $100 and can't exceed that.

Select the correct answer. Martin runs 100 meters in 15 seconds. What is the equation for d, the distance in meters that Martin covers per second? O A. 15+ d = 100 B. 100 + d = 15 O c. dx 15 = 100 D. d x 100 = 15​

Answers

Answer:

C) d*15=100

Step-by-step explanation:

The word problem already gives us the product or the end result “Martin runs 100 meters in 15 seconds. So the 100 has to be equal to the expression.

=100

“Per second” this suggests that we should multiply

the most logical answer is d*15=100 or dx15=100

An urn contains 11 balls, 3 white, 3 red, and 5 blue balls. Take out two balls at random, without replacement. You win $1 for each red ball you select and lose a $1 for each white ball you select. Let X be the random variable that notes the amount you win. Find the probability mass function (p.m.f.) of X.

Answers

Answer with explanation:

Given: An urn contains 11 balls, 3 white, 3 red, and 5 blue balls.

You win $1 for each red ball you select and lose a $1 for each white ball you select.

Let X be the number of times you win.

The total number of ways to select 2 balls (order does not matter) =

The number of ways so that two balls are white (and X=-2):^3C_2=3

P(X=-2)=(3)/(55)

The number of ways so that two balls are red (and X=2):^3C_2=3

P(X=2)=(3)/(55)

The number of ways so that one ball is red, one is white (and X=0):^3C_1*^3C_1=9

The number of ways so that two balls are blue (and X=0 ): ^5C_2=(5 \cdot 4) / 2=10

i.e. P(X=0)=(10+9)/(55)=(19)/(55)

The number of ways so that one ball is blue, one is white (and X=-1 ): ^5C_1*^3C_1=15

P(X=-1)=(15)/(55) =(3)/(11)

The number of ways so that one ball is blue, one is red (and X=1 ): ^5C_1*^3C_1=15

P(X=1)=(15)/(55) =(3)/(11)

Thus, the probability mass function (p.m.f.) of X would be ( in attachment) :

8x - 3 = 5 (2x + 1) solve for x

Answers

Answer:

-4

Step-by-step explanation:

Given:

  • 8x - 3 = 5 (2x + 1)

Solving for x:

  • 8x - 3 = 10x + 5
  • 10x - 8x = -3 - 5
  • 2x = - 8
  • x = -8/2
  • x = -4

Answer:

x=−4
