The sector of a circle with a 12 in. radius has a central angle measure of 60°. What is the exact area of the sector in terms of

Lana71 [14]

That is angle/360 times area

area=pir^2
r=12 in this one
and angle=60
so
60/360 times pi12^2=1/6 times 144pi=24pi square inches

Which phrase best describes the scatterplot below? strong negative correlation strong positive correlation weak negative correla

s344n2d4d5 [400]

*the scatter plot of the question is attached below

Answer:

Strong negative correlation

Step-by-step explanation:

In the scatter plot attached below, as the variable in the x-axis increases, the variable on the y-axis decreases. Thus, if a line of best fit is drawn, it would show a line that slopes downwards to our right. This shows a negative correlation between both variables in the scatter plot.

Also, we also see that the data points represented on the scatter plot are clustered more closely along the slope, showing strong negative correlation.

Therefore, the phrase that best describes the scatter plot is: strong negative correlation.

The table below shows all of the possible outcomes for rolling two six sided number cubes what is the probability of rolling an

Vanyuwa [196]

<u>Answer:</u>

The probability of rolling an even number first and an odd number second is $\frac{1}{4}$

<u>Solution: </u>

As two cubes are 6 sided, the total number of possibilities are $(6\times6) = 36$

Now in those possibilities the first number will be even and the second number will be odd. If we check the table, such pairs are,

(2,1), (2,3), (2,5), (4,1), (4,3), (4,5), (6,1), (6,3), (6,5)

So, we can see we have total 9 set with the combination of first number even and second number odd. So, the probability of rolling with this combination will be $\bold\frac{9}{36}=\frac{1}{4}\bold$
