The formula for the circumference is C=2piR (r is radius)

If the flagpole is in the center and it's 15 feet to the edge, that means that 15 feet is the radius. Draw it out, you'll see. Now you plug 15 into the formula, either use a calculator or don't, and solve. You will get
94.2 as your circumference.

C=pi times Radius squared

First input what you know which is C=3.14x15x15
Multiply 15 times 15 which equals 225, so now you have C=3.14x225
Multiply 3.14x225 which gives you the circumference which is 706
So C=706.5

What is an equation of the line that passes through the points (-3,-1) and
NARA [144]

The equation of line that passes through the points (-3,-1) and

(-6,3) is:

y=-\frac{4}{3}x-5

Step-by-step explanation:

Given points are:

(-3,-1) =(x1,y1)

(-6,3)=(x2,y2)

The slope-intercept form of equation of line is:

y=mx+b

We have to find the slope first

m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{3-(-1)}{-6-(-3)}\\=\frac{3+1}{-6+3}\\=\frac{4}{-3}

Putting the value of slope in the slope intercept form

y=-\frac{4}{3}x+b

To find the value of b, putting the point (-3,-1) in the equation

-1=-\frac{4}{3}(-3)+b\\-1= 4+b\\b=-4-1\\b=-5

Putting the values of b and m

y=-\frac{4}{3}x-5

The equation of line that passes through the points (-3,-1) and

(-6,3) is:

y=-\frac{4}{3}x-5

Keywords: Equation of line, slope intercept form

A cat gave birth to 3333 kittens who each had a different mass between 147147147147 and 159 g159\,\text{g}159g159, start text, g
harina [27]

Answer:

The correct option is (B).

Step-by-step explanation:

The median (m) is a measure of central tendency. To obtain the median, we assemble the data in arising order. If the data is odd, the median is the mid-value. If the data is even, the median is the arithmetic-mean of the two mid-values.

The mean of a data set is:

\bar X=\frac{1}{n}\sum\limits^{n}_{x=0}{X}

For the three kittens it is provided that the weights are in the range 147 g to 159 g.

So, the mean and median weight for the 3 kittens lies in the middle of this range.

Now a fourth kitten is born, with weight 57 g.

Now the range of the weight of 4 kittens is, 57 g to 159 g.

The mean is going to decrease as one more value is added to the data and the value is the least.

The median will also decrease because now the median will be mean of the 2nd and 3rd values.

But the mean would decrease more than the median because a smaller value is added to the data.

Thus, the correct option is (B).
