<u>Answer-</u>

Ed exhibited the most variable year to year performance over this 5 year span.

<u>Solution-</u>

Most variable performance means varying performance or non-consistence performance.

As shown in the graph,

Jill's performance was constant throughout 2005-07.

Ralph's performance was constant throughout 2006-07 and also in 2008-09.

Tina's performance was constant throughout 2007-09

Sam's performance was constant throughout 2008-09.

All of them has been consistence for at-least once. But, in case of Ed, throughout the time, his performance was in-consistence or variable.

The teacher that exhibited the most variable year to year performance over this 5 year span is Jill. Even though she started out at a constant rate from 2005 to 2007, her performances gradually increases in the year 2007 and beyond.

The area of a circle is 43.25cm2.<br> Find the length of the radius rounded to 2 DP.

Monica [59]

Answer:

3.71 cm

Step-by-step explanation:

Hi there!

Area of a circle equation: $A=\pi r^2$ where r is the radius

Plug in the area 43.25 cm²

$43.25=\pi r^2$

Divide both sides by π to isolate r²

$\frac{43.25}{\pi} =\frac{\pi r^2}{\pi} \\\frac{43.25}{\pi}=r^2$

Take the square root of both sides to isolate r

$\sqrt{\frac{43.25}{\pi}} =r\\3.71=r$

Therefore, the length of the radius rounded to 2 decimal points is 3.71 cm.

I hope this helps!

The two-way table shows the number of people whose hobbies are reading or solving puzzles and who either ride a motorcycle or do

enot [183]

The number of people whose hobby is reading but not riding a motorcycle is 5.

<h3>What is the relative frequency of not riding a motorcycle?</h3>

We want to calculate the number of people whose hobby is reading but they don't like riding the motorcycle,

therefore, when we look into the table we will find out that block A2 is the block that represents the number of people whose hobby is reading but not riding a motorcycle.

Hence, the number of people whose hobby is reading but not riding a motorcycle is 5.

What is the point-slope form of the equation of a line that passes through the point (1, 4) and has a slope of −3?

zmey [24]

So y=mx+b
m=slope

y=-3x+b
subsitutue 1 for x and 4 for y
4=-3(1)+b
4=-3+b
add 3 to both sides
7=b

the equaiton is y=-3x+7
