Write and solve a problem for 42 divided 7 in which the quotient is the number of groups

jasenka [17]

The hardest part is finding the length of the curve at the top. To find arc length, multiply the circumference by the arc angle divided by full angle (360°) in a circle. Or:
$s = (2\pi r)( \frac{x}{360})$
x, the arc angle in a semicircle, is 180°.
r, the radius is 7/2 = 3.5.
Now just plug the numbers in and solve for arc length, s.

s = 2π(3.5)(1/2) ≈ 11.00

Now just add up all the sides. 11cm + 10cm + 10cm + 7cm = 38 cm.

60 POINTS!!!!!!!!!! If each square of the grid below is 0.5 cm by 0.5 cm, how many centimeters (cm) are in the perimeter of the

Aleks04 [339]

Answer:

21 cm

Step-by-step explanation:

The perimeter is the length of the outside of a shape. In this case, we can simply add up all the edges and multiply by .5(the length of one edge).

Horizontal Edges: 22

Vertical Edges: 20

Total: 42

Perimeter = $42 * 0.5 = 21 cm$

Please help me!! will give you brainliest!!!

1. ( -1,2) is the same as (x=-1, y=2)
Substitute in your equation
y=3x-2
2=3•(-1)-2
2=-5 this is NOT true so (-1,2) is not a solution for the equation y=3x-2

2. (0,-2)
9x-6=3y
9(0)-6=3•(-2)
-6=-6 this is true so ( 0, -2) is a solution for the given equation

A student wants to report on the number of movies her friends watch each week. The collected data are below: 2 14 1 2 0 1 0 2 Wh

Sunny_sXe [5.5K]

The student's friend watch 1.5 movies every week.

Data provided to us {2, 14, 1, 2, 0, 1, 0, 2}.

Number of data values = 8

Sorted or rearranged data {0, 0, 1, 1, 2, 2, 2, 14}

Median of the data provided;

Median is the mid point value of the data provided to us, but as in this case there are 8 data provided (even number of data), we will take the average of the 2 mid values of the data.

Mid Values = 1 and 2

$\bold{Median=\dfrac{1+2}{2} = 1.5}$

Mean of the data provided;

$Mean=\dfrac{Sum\ of\ all\ data\ values}{Number\ of\ data\ values} \\\\Mean= \dfrac{(0+0+1+1+2+2+2+14)}{8}\\\\Mean=2.75$

As we know, The data values provided are 0, 1 and 2, and there is 14 as well in the data which is the maximum value in the data provided to us but the value is far from the other data values provided to us. Therefore, the data value 14 is considered to be an outlier.

An outlier is the maximum value that increases the mean, which makes it larger than it should be.

If we were to compute the mean without the outlier,

$Mean=\dfrac{Sum\ of\ all\ data\ values}{Number\ of\ data\ values} \\\\Mean= \dfrac{(0+0+1+1+2+2+2)}{7}\\\\Mean=1.1428$

Now, we have understood that the mean is sensitive to outlier can be easily manipulated. thus, mean is not the right option to go for in this case.

Therefore, the median value of 1.5 is the right option.

Hence, the student's friend watch 1.5 movies every week.
