Answer:

Positive association

Step-by-step explanation:

You can see the weight go up by the model number going up, if you put it on a graph it will show the trend line going up.

So say

"This has a positive association because the weight is going up while the model # is going up. thus gives a positive association when graphed"

ABCD ~ EFGH

vredina [299]

Answer:

FG = 20 in

Step-by-step explanation:

∵ ABCD ≈ EFGH

∴ AD/EH = BC/FG

∵ AD = 45 in

∵ EH = 60 in

∴ BC = 15 in

∴ 45/60 = 15/FG

∴ FG = (60 × 15) ÷ 45 = 20 in

A circle has a central angle measuring startfraction 7 pi over 6 endfraction radians that intersects an arc of length 18 cm. wha

mash [69]

The radius of this circle is (B) 4.9 cm.

<h3>To find the radius of the circle:</h3>

To solve this problem, we need to, first of all, convert the angle from radians to degrees.

data;

length of an arc = 18cm
angle = 7/6π rads
π= 3.14

$\frac{7\pi }{6rads} =210^{0}$

Length of an Arc:

The formula for the length of an arc is given:

$l_{arc} =$ θ/360 × $2\pi r$

Let's substitute the values and solve:

$18=\frac{210}{360} *2\pi r\\18=3.663r\\r=\frac{18}{3.663} \\r=4.9cm$

From the calculations above, the radius of this circle is 4.9cm.

Therefore, the radius of this circle is (B) 4.9 cm.

People who said yes: $24-18=6$

Decimal: $\frac{6}{24} = \frac{6/6}{24/4} = \frac{1}{4} =0.25$

Percentage: $0.25*100=25$ --> 25%
