The mean is usually the preferred measure of central tendency, but there are specific situations in which it is impossible to compute a mean or in which the mean is not particularly representative of the distribution. Which of the following statements about the mean are true?

a. It is commonly referred to as the arithmetic average.
b. It is algebraically defined (that is, there is an equation you can use to calculate its value).
c. It is easily influenced by extreme scores.
d. It can be used for data that are measured on a nominal scale.

Answer:1 inch per minute in/min = 0.017 inches per second in/sec

Step-by-step explanation:

The arc length of the sector will be 19.89 centimeters.

Let r is the radius of the sector and θ be the angle subtended by the sector at the center. Then the arc length of the sector of the circle will be

Arc = (θ/2π) 2πr

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The radius of the sector is 4 cm. And the central angle is 285°.

Then the perimeter of the sector is given as,

Arc = (285° / 360°) x 2 x 3.14 x 4

Arc = 19.89 cm

The arc length of the sector will be 19.89 centimeters.

More about the arc length of the sector link is given below.

Answer:

The exact value of [tex]10\cdot a[/tex] is [tex]253.77^{\circ}[/tex].

Step-by-step explanation:

Sine function is a bounded function between -1 and 1 and positive in the first and second quadrants. From statement we deduct that [tex]a[/tex] is in the first quadrant, that is, [tex]0^{\circ}< A < 90^{\circ}[/tex]. Then, we determine the angle by inverse trigonometric function:

[tex]A = \sin^{-1} \frac{3}{7}[/tex]

[tex]A \approx 25.377^{\circ}[/tex]

Then, the exact value of [tex]10\cdot a[/tex] is [tex]253.77^{\circ}[/tex].

Answer:

12

Step-by-step explanation:

substitute x = 7 into the equation:

[tex]4 (7-4)\\4(3)\\12[/tex]

Answer:

12

Step-by-step explanation:

First, you insert the 7 in place of the x. Then you do what is in the parenthesis, according to PEMDAS. 7-4 = 3. You end up with 4(3). You then do distributive property and you end up with 12.

Answer:

Step-by-step explanation:

Answer:

Associative

Step-by-step explanation:

Answer:

f(4) - g(3) = 28

Step-by-step explanation:

f(x) = 8x + 10

f(4) = 8(4) + 10

f(4) = 32 + 10

f(4) = 42

g(x) = 6x - 4

g(3) = 6(3) - 4

g(3) = 18 - 4

g(3) = 14

f(4) - g(3)

= 42 - 14

= 28

Answer:

Triangle C

Step-by-step explanation:

Given

Triangle A, B, C and D

Required

Pick the odd triangle

From the attachment, we can see that:

A = Right angled triangle

B = Right angled triangle

C = Obtuse triangle

D = Right angled triangle

This is so because triangle C has one of its angles to be greater than 90 (i.e. 115) and other triangles (A, B and D) have an angle equal to 90, each.

Because C is obtuse and others are right-angled, then C is the odd triangle.

Answer:

x= -1/3

y= -3 1/3

Step-by-step explanation:

Make both of them into y=Mx+b form

y=-x-3

y=(-x-7)/2

Substitute the x-3 in the first equation for the y in the second one.

x-3=(-x-7)/2

2x-6=-x-7

3x=-1

x=-1/3

Now that we have x, we can solve for y.

y=-x-3

y=-1/3-3

y=-3 1/3

Answer: x=6

Step-by-step explanation:

Answer:

(1.5,-4) top left (-1.5,4)

Step-by-step explanation:

The point lies in the bottom right at (1.5,-4), and if you reflcting it across the x and y axis the point is going to be in the oppisite quadrant and oppisite of the original point. example if the coordinates are X value, reflecting them will make it -x, making positves negatives and vice versa.

Answer:

48 square inches

plz mark brainliest

Step-by-step explanation:

l= 3w

perimeter = 2(l+w) =2(3w+w) = 2(4w)= 8w

32=8w

w=32/8 =4 inches

l= 3(4) =12 inches

area = l×w = 12×4 = 48 square inches
