Answer:

A. (4,3)

Step-by-step explanation:

The vertex of a parabola is the maximum or minimum point on the graph of the quadratic function aka where you just have "one value" wether than be the very top, the very bottom, etc

In summary:

Here we can see it'll be the very bottom as the parabola is angled upwards.

Looking at the graph, we can see it is 4 units to the right and 3 units up.

The first number is the x, or the right/left, so our first number is 4

The second number is our y, or the up/down, so our second number is 3

This leaves us with the point (4, 3) and an answer of A!

Hope this helps, have a nice day :D

six people, including A,B, and C, form a queue in a random order (all 6! orderings are equiprobable). Consider the event "B is b

mojhsa [17]

Answer:

There is a 1.39% probability that "B is between A and C in the queue".

Step-by-step explanation:

The first step to solve this problem is find the total number of possible orderings:

The first person of the queue can be any of the six. The second, can be any but the first, so five.

There are 6*5*4*3*2*1 = 720 total queue orderings.

Now we find the number of queues that B is between A and C. So:

We have:

B as the second, A as the first and C as the third

B as the second, C as the first and A as the third

B as the third, A as the second and C as the fourth

B as the third, C as the second and A as the fourth

B as the fourth, A as the third and C as the fifth.

B as the fourth, C as the third and A as the fifth.

B as the fifth, A as the fourth and C as the sixth.

B as the fifth, C as the fourth and A as the sixth.

So 8 total outcomes in which B is between A and C.

What is its probability?

$P = \frac{8}{720} = 0.0111$

There is a 1.11% probability that "B is between A and C in the queue".

Nataly [62]

<h2>Answer:</h2><h2>2 hours & 10 minutes </h2><h2>Step-by-step explanation:</h2><h2>1/6 of an hour is 10 minutes. She vacuumed for 10 minutes. It took 4 times as long to wash the car so 10 * 4 = 40. She washed the car for 40 minutes. It took her twice as long to wax the car as it did for her to wash it so 40 * 2 = 80. She waxed the car for 80 minutes. 10 + 40 + 80 = 130 minutes or 2 hours and 10 minutes. </h2>
