A spinner and 2 cards are shown below:A spinner with 7 equal sectors is shown in the figure. The colors Green, Red, Orange, Violet, Pink, Yellow, and Blue are marked on it. The arrow points at the red color. Two cards are shown on the right side. The colors Purple and Green are marked on them.

Sophie spins the spinner and picks up a card without looking. What is the probability that the spinner stops at red and a green card is selected?

1 over 49
1 over 16
1 over 14
1 over 2

Answers

Answer 1

Answer: P(red AND green card) = P(red) * P(green card)

P(red) = 1/7 (i.e. one color out of total of seven)
P(green card) = 1/2 (i.e. one card out of two)

P(red AND green card) = 1/7 * 1/2 = 1/14

Answer 2

Answer:

Hence, probability that the spinner stops at red and a green card is selected is:

1 over 14

Step-by-step explanation:

It is given that a spinner and two cards are selected.

A spinner has 7 colors in it:

Green,Red,Orange, Violet, Pink, Yellow, and Blue are marked on it.

Two cards are shown on the right side. The colors Purple and Green are marked on them.

Now we are asked to find the probability that the spinner stops at red and a green card is selected.

Let A denotes the event that the arrow stops at red.

and B denote the event that a green card is selected.

Now, we have to find:

P(A∩B)

Where P denotes the probability of an event.

As we know that event A and event B are independent.

Hence,

P(A∩B)=P(A)×P(B)

Now,

P(A)=1/7

( Since we have 7 choices out of which only one sector has red color)

Similarly,

P(B)=1/2

( since we have just two cards and one card is green).

Hence,

P(A∩B)=(1/7)×(1/2)=1/14

Hence, probability that the spinner stops at red and a green card is selected is:

1 over 14

Rick used 4 2/3 yards of fabric to sew 3 1/2 shirts. what is the unit rate of cloth he used in terms of yards per shirt

Answers

For sewing 3 1/2 shirts, he used = 4 2/3 yards of fabric
Then, for 1 shirt, it would be: 4 2/3 / 3 1/2

Fabric for 1 shirt = 14/3 / 7/2
We can re-write it as: 14/3 * 2/7 = 4/3 yards

In short, Final answer would be 4/3 or 1 1/3 yards

Three families each have three sons and no daughters. Assuming boy and girl babies are equally likely, what is the probability of this event?

Answers

I don't think it matters how many families are involved.
You're talking nine live births, and the probability of a
male birth each time is 50% .

So the probability of nine males in nine births is

(1/2)^9 = 1/512 = about 0.195 percent (rounded)

three families with three children all boys
parents-2
children-3
total-5 times 3= 15
then boys-3 times three=9

Answer: 9/12

Does anyone know how to to explain slope in a easy way

Answers

When you are given two points of a line, you can find the slope of the line.

Let's say that the two points we are given is $\sf(x_1,y_1) ~and ~(x_2,y_2)$ , then the slope is:

$\bf{Slope = (y_2-y_1)/(x_2-x_1)$

Another thing to keep in mind:

When you have 0 in the numerator, and a number in the denominator, that means that the slope is 0.
When you have 0 in the denominator, and a number in the numerator, that means that there is no slope, or that the slope is undefined.

Answer:

23/99

Step-by-step explanation:

0.23 is x.

Because x is recurring in two decimal places, we will multiply it by 100.

100x=23.23

Then we subtract.

100x-x=23.23-0.23

99x=23

x=23/99
