The correct answer is other measures of location need not be the same.

What is mean, mode, median and standard deviation?

When the group of numbers have the same mean then the other measures of location need not be the same. That means the standard deviation, median and mode should not be equal. All three widely used parameters that are mean, mode, median and standard deviation are the measure of central tendency.

If the given data has no outlier then mean value and the median value are closer to each other but the mode value is different. Similarly, standard deviation is calculated for the dispersion data. And it means when mean value is same then standard deviation will be different for a group of numbers.

A conclusion which can be inferred about an individual score that corresponds to a z-value of 1.0 is that: c.) it is likely to come from the healthy distribution.

A z-value is also referred to as a z-score or standard score and it can be defined as a measure of the distance between a raw score and the mean, when standard deviation units are used.

In Statistics, z-values can either be positive or negative and it can be calculated by using this formula:

[tex]Z=\frac{x\;-\;u}{\delta}[/tex]

Answer:

a = -30

Step-by-step explanation:

In order to solve for a in the equation [tex]\sf 11 = \dfrac{-3}{10} a + 2[/tex], we can follow these steps:

Subtract 2 from both sides of the equation:

[tex]\sf 11 -2= \dfrac{-3}{10} a + 2-2[/tex]

[tex]\sf 9 = \dfrac{-3}{10} a[/tex]

Multiply both sides of the equation by [tex]\sf -\dfrac{10}{3}[/tex]:

[tex]\sf 9 *-\dfrac{10}{3}= \dfrac{-3}{10} a*-\dfrac{10}{3}[/tex]

-30 = a

Therefore, the solution to the equation 11 a + 2[tex]\sf \dfrac{-3}{10} a + 2[/tex] is a = -30.

Answer: 24

Step-by-step explanation:

t=seconds. h=height

t=3

h=3+55t-16t^2

h=3+55(3)-16(3)^2

h=3+165-16*9

h=168-144

h=24 ft

The ball's height 3 seconds after it was kicked is 24 feet above the ground.

Given that a formula h = 3 + 55t-16t² describes a ball's height above the ground h, which has been kicked vertically upward from a height of 3 feet with an initial speed of 55 feet per second.

We need to find the height of the ball after 3 seconds.

To find the ball's height 3 seconds after it was kicked, we can use the formula provided:

h = 3 + 55t - 16t²

where h represents the height in feet and t represents the time in seconds.

To find the height after 3 seconds (t = 3), plug the value into the formula and calculate:

h = 3 + 55(3) - 16(3)²

Now, perform the calculations step by step:

h = 3 + 55(3) - 16(9)

h = 3 + 165 - 144

h = 24 feet

Hence the required height is 24 feet.

From the inequality given by -2w < 24, w is greater than -12.

Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.

Solving the inequality,

-2w < 24

Making sure the unknown variable is in one side and the constants in the other side.

-2w < 24

Divide both sides by -2, the coefficient beside the unknown variable,

(-2/-2)w < 24/-2

w < -12

Note that when we multiply or divide by a negative number

we must reverse the inequality.

w < -12 ⇒ w > -12

Therefore, w is greater than -12.

The original price of the table set was $400.

Customers are given discounts by shop owners in order to increase sales. A discount is a rebate or offer created to consumers on the listed price of goods.

Now, as per the given question;

The paid price by Maria is $240 called selling price.

The total discount on the table set was 40%.

Let us consider the original price/marked price of the table set was 'x'.

Then the formula for calculating the original price/market price is;

Marked price - discount = selling price

x - 40%of x = 240

x - (40x)/100 = 240

100x - 40x = 24,000

60x = 24,000

x = 400

Therefore, the original price of the table set was $400.

The probability that four or fewer of the people who called will sign up for a class = 0.9805

For given question,

Eric estimates that one out of every five people who call for information about a class will sign up for the class.

Last week he receive nine calls.

We need to find the probability that four or fewer of the people who called will sign up for a class.

Total number of calls = 9

⇒ n = 9

Since one out of every five people who call for information about a class will sign up for the class.

the probability of success (p) = 1/5

                                                  = 0.2

and the probability of failure (q) = 1 - p

                                                      = 1 - 0.2

                                                      = 0.8

To find the probability that four or fewer of the people who called will sign up for a class.

So, x would take values 0, 1, 2, 3, 4

Using Binomial principal,

For x = 0,

[tex]P(x=0)= ~^9C_0(0.2)^0(0.8)^{9-0}\\\\P(x=0)=0.13422[/tex]

For x = 1,

[tex]P(x=1)= ~^9C_1(0.2)^1(0.8)^{9-1}\\\\P(x=1)=0.30199[/tex]

For x = 2,

[tex]P(x=2)= ~^9C_2(0.2)^2(0.8)^{9-2}\\\\P(x=2)=0.30199[/tex]

For x = 3,

[tex]P(x=3)= ~^9C_3(0.2)^3(0.8)^{9-3}\\\\P(x=3)=0.17616[/tex]

For x = 4,

[tex]P(x=4)= ~^9C_4(0.2)^4(0.8)^{9-4}\\\\P(x=4)=0.06606[/tex]

So, the required probability would be,

P = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4)

P = 0.1342 + 0.3020 + 0.3020 + 0.1762 + 0.0661

P = 0.9805

Therefore, the probability that four or fewer of the people who called will sign up for a class = 0.9805

The slope of the given function is not constant therefore it will not be a linear function so option (A) will be correct.

A straight line on the coordinate plane is represented by a linear function.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

Given the data table,

If we take its point as coordinate then (1,6),(6,27),(11,50)(13,56) and (16,70).

Slope associated with two points (1,6), (6,27)

(27 - 6)/(6 - 1) = 4.2

Now Slope is associated with two points(6,27),(11,50)

(50 - 27)/(11 - 6) = 4.6

Since the slope is not the same therefore given function is not the linear function because the linear function has a constant slope.

Hence "The slope of the given function is not constant therefore it will not be a linear function".
