Any sample would need to be random. However, we can assume that people may come to the bagel shop at all times it is open, and their opinions would be different from others. So, we should take a stratified sample of each hour the bagel shop is open. For example, we would randomly select a number of customers from 8 - 9, say, and continue that process for each hour the bagel shop is open.

Hope this helps!! :)

HIJK is a parallelogram because the midpoint of both diagonals is ____ which means the diagonals bisect each other.
just olya [345]
ANSWER

The midpoint of both diagonals is

(1,0)
EXPLANATION

We can use either diagonals to determine the midpoint.

We use the midpoint formula

( \frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2} )

Let us use the first diagonals H(-2,2) and J(4,-2)

( \frac{ - 2 + 4}{2} , \frac{ - 2+ 2}{2} )

( \frac{ 2}{2} , \frac{ 0}{2} )

( 1, 0)

Using the second diagonals also gives,

( \frac{ - 2 + 4}{2} , \frac{ - 3+ 3}{2} )

( \frac{ 2}{2} , \frac{ 0}{2} )

( 1, 0)

An urn contains 2 red marbles and 3 blue marbles. 1. One person takes two marbles at random from the urn and does not replace th
Strike441 [17]
<h2>Answer with explanation:</h2>

Given : An urn contains 2 red marbles and 3 blue marbles.

Total marbles = 2+3=5

a) The general ways in which the person could get a red marble and a blue marble are :

1)  He draws red marble first and then second marble as blue.

2)  He draws blue marble first marble and then second marble as red.

b)  The number of ways to get one red and one blue marble is given by :-

^2C_1\times^3C_1=2\times3=6                          (i)

c) Number of ways to get 2 marbles from 5 is given by :-

^5C_2=\dfrac{5!}{2!(5-2)!}=\dfrac{5\times4\times3!}{3!\times2}=10     (ii)

Now, The probability the person gets a red and a blue marble will be :-

P(R\ \&B)=\dfrac{6}{10}=0.6       [Divide (i) by (ii)]

Hence, the  probability the person gets a red and a blue marble= 0.6

Jason wanted to place all 540 marbles in the 3 newly bought boxes. If he wants to
kotegsom [21]

Answer:

The first box will have 90 marbles, the second 180 and the third 270.

Step-by-step explanation:

Division in a ratio of 1:2:3

1 + 2 + 3 = 6

So

The first box will have 1/6 of the marbles.

The second box will have 2/6 = 1/3 of the marbles

The third box will have 3/6 = 1/2 of the marbles.

First box:

One sixth, so:

(1/6)*540 = 540/6 = 90

Second box:

One third, so:

(1/3)*540 = 540/3 = 180

Third box:

One half, so:

(1/2)*540 = 540/2 = 270

The first box will have 90 marbles, the second 180 and the third 270.
