draw an array to show how to arrange 20 chairs into 5 equal rows. Explain what each part of the array represents.

Answers

Answer 1

Answer: Since there are 20 chairs and should be arrange into 5 equal rows. So the number of chairs in each row is equal to 20 / 5 which equal to 4. so let x represent a chair in the array. so the drawing should be like:
x x x x
x x x x
x x x x
x x x x
x x x x

A spinner and 4 cards are shown below: A spinner with 5 equal sectors is shown in the figure. The colors Green, Blue, Purple, Yellow, and Red are marked on it. The arrow points at the purple color. Four cards are shown on the right side. The colors Red, Yellow, Blue, and Pink are marked on them. Jane spins the spinner and selects a card without looking. What is the probability that the spinner stops at purple and a pink card is selected?

Answers

The probability that the spinner stops at purple and a pink card is selected is 80%.

We have given that,a spinner with 5 equal sectors is shown in the figure.

What is the formula probability?

$P=(number of feverable outcome )/(Total number of outcome )$

The spinner has a 1/5 chance of landing on purple, since the number of favorable outcomes is the numerator, and the number of possible outcomes is the denominator.

There are total four cards, which means we have a 1/4 chance of picking pink,

for the samereason as above.

Therefore 1/5 x 1/4 = 4/5

4/5 =0.80= 80% chance.

EXPLANATION

In linear functions we often have the slope-intercept form of the equation:

$f(x)=mx+b$

Which can also be written in a different order, for example:

$f(x)=b+mx$

m is the slope of the line. The slope of the graph of a function is the rate of change.

b is the y-intercept. This
