Konrad has $500 in a savings account at the beginning of the summer. He wants to have more than $200 in the account by the end of the summer. He withdraws $25 each week for food, clothes, and movie tickets. How many weeks can Konrad withdraw money from his account?

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

He has $500 to start with, and he takes $25 out of the account each week. But he wants more than 200 in his account by the end of summer. 25 goes into 500 20 times. But if he wanted more than 200 left, like 300-400, he could spend 4 week's worth of money to have 400 left, or 8 weeks to have 300 left. This is the best-case scenario.

The numbers 4, 5, 6, and 7 are on a spinner. You spin the spinner twice. Which calculation proves that landing on an even number for the first spin and the second spin are independent events?

Answers

Not sure what that dude is even saying. The answer is C- P(A and B)=2/4*2/4

Hope this helped.


Answer:

As long as the numbers are in equal proportion on the spinner, the probabilty of landing on an even number for the first and second spin is 1/4, or 25%.  

Step-by-step explanation:

If there are four numbers on a spinner, all in equal proportion, than the probability of getting an even number (either 4 or 6) on any spin is 2/4, or 1/2, which is also 50%.  Since the results of the first spin do not influence the results of the second spin, then they are independent events.  So, if the likelihood of landing on even each time is 1/2, then we would mutliply 1/2 by 1/2 in order to find the probability that landing on an even number would happen in both spins.  Our result would be 1/4, or 25%.

What is the solution to the system of equations? y=2/3x+3 x=-2

Answers

Answer:

x=-2,y=(5)/(3)

Step-by-step explanation:

The given system of equations is

y=(2)/(3)x+3...(i)\n\nx=-2...(ii)

Plugging the value of x from (ii) in equation (i) and find the value of y

y=(2)/(3)*(-2)+3\n\ny=(-4)/(3)+3\n\ny=(5)/(3)

Therefore, the solution of the system of equations is

x=-2,y=(5)/(3)

We are going to solve for x=-2, y=2/3x+3, y=2/3(-2)+3, y=5/3. Therefore, x=-2 and y=5/3
