Standard deviation is a statistical measure of how much scores in a sample vary around the mean. The correct option is B.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

Therefore, the standard deviation is a statistical measure of how much scores in a sample vary around the mean. The correct option is B.

Answer:

5 m/s²

Step-by-step explanation:

To find the acceleration we apply Newton's second law of motion

F = ma   where F is the net force in Newtons, m the mass of the object (kg) and a the acceleration in  meters/second² (m/s²)

Given

F = 200 N

m = 40 kg

we have 200 = 40a

So a = 200/40=5 m/s²

D) 2.65 gallons of gas left in his car after taking both friends home when 1.05 gallons of gas is used to take one friend home and three tenths gallon to take the other friend home.

Manny used 1.05 + 0.3 = 1.35 gallons of gas to take his friends home.

Since he originally had 4 gallons of gas, he had 4 - 1.35 = 2.65 gallons of gas left in his car after taking both friends home.

So the answer is D.

Here is the solution in more detail:

Manny started with 4 gallons of gas.

He used 1.05 gallons of gas to take one friend home.

He used 0.3 gallons of gas to take the other friend home.

The total amount of gas he used was 1.05 + 0.3 = 1.35 gallons.

Therefore, he had 4 - 1.35 = 2.65 gallons of gas left in his car.

Answer: y = 6.75x + 6

Step-by-step explanation:

Answer:

y=6.75x+6

Step-by-step explanation:

y=mx+b

we can find it by doing [tex]\frac{y^{2}-y^{1} }{x^{2} -x^{1} }[/tex]

I'm going to choose 2,19.5 and 5,39.75

[tex]\frac{39.75-19.5}{5-2}[/tex] we get [tex]\frac{20.25}{3}[/tex] simplified to 6.75

now we know that the slope is 6.75 we can find the y-intercept by plugging in one pair, I'm going to put the 2,19.5 in

19.5=(6.75)2+b then multiply 6.75 by 2

19.5=13.5+b then subtract 13.5 from both sides to remove the 13.5 on B to separate it

6=b so the y-intercept is 6

The measure of the corresponding central angle for XY in radians is; 229.1°

We know that an arc is a part of the entire perimeter of a circle.

Radian is defined as a unit of plane angular measurement that is equal to the angle subtended by the circle at the center by an arc that is of the length equal to the radius.

We also know that the circle as a whole contains 2π radians. Now, at first we are required to find the perimeter of the circle.

Perimeter of the circle is given by the formula 2πr.

Thus, perimeter of the circle = 2πr = 2π * 10 =20π = 62.851cm

Hence value of arc in radians = 40/62.851 * 2π = 0.636 x 2 π = 1.272π

Radian can be converted to degree by multiplying the radian measure by 180/π

Therefore, angle subtended by arc in degrees =1.272 π * 180 /π =229.1 °

Hence the angle subtended by arc is 229.1°

Answer: A

Step-by-step explanation:

Multiply the first equation by 7 and the second equation by 2, and then add.

2f - 5g=-9

-7f + 3g=4

To eliminate any variable , we need to make the coefficients same with different sign and add it

the coefficient of 'f' in first equation is 2

the coefficient of 'f' in second equation is -7

We already have different sign so we make the coefficients same

To make the coefficient same , we multiply the first equation by 7  and second equation by 2

So equation becomes

14f - 35g = -63

-14f + 6g = 8

Now when we add both equations, 'f' gets cancelled

The dimension of the base of the rectangular building is 340 x 135ft.

Perimeter of Rectangle:

The definition of perimeter of the rectangle is the total length or distance of its boundary on all sides.

The general formula to calculate the Perimeter of a rectangle is,

P = 2(l + w)

Where,

l represents the length of the rectangle

w represents the width of the rectangle.

Given,

The building in a city has a rectangular base. the length of the base measures 65ft less than three times the width.

The perimeter of this base is 910ft.

Now, we need to find the dimensions of the rectangular base.

According to the given details, the values of

L = 3W - 65

W = W

P = 910

Apply the values on the formula, then we get,

=> 910 = 2 * (L + W)

=> 910/2 = (L + W)

=> 455 = L + W

Apply the value of L,

=> 475 = 3W - 65 + W

=> 475 + 65 = 4W

=> 540 = 4W

=> 540/4 = W

=> W = 135

Apply the value of W as 135, in order to get the value of L,

=> L = 3*135 - 65

=> L = 405

=> L = 340

Therefore, the dimension of the rectangular base is 340 x 135 ft.
