if we have a class of 15 students and we want to choose a committee of 5 students, their order and position don't matter, 3003 many different ways are there of creating a 5-person committee among the 15 students.

The combination formula is used to determine how many options there are for choosing things from a collection so that the order in which they are chosen is irrelevant. Combination, to put it simply, is the choosing of items or things from a bigger group when the order doesn't important.

Since order and position doesn't matter in this problem, use the combination formula.

The combination formula is: n! / (n-r)! r!

where n is the total number of items (15 in this case) and r is the number of items being selected at once (5 in this case)

Plugging our numbers into the formula:

= 15! / (15-5)! 5!

= 3003 ways.

So, there are 3003 ways of picking 5 people from a group of 15.

Answer:

Yes, both men could drive at the rate of 112 miles in 2 hours. This is because you need to find the unit rate. For Theo's unit rate it is 57 miles per hour while Lex could drive at 62 miles per hour. Finally, the last statement ask if they could drive at a unit rate of 56 miles per hour and yes both men can.

Step-by-step explanation:

Answer: Theo's speed is 240 miles / 4 hours = <<240/4=60>>60 mph.

Lex's speed is 183 miles / 3 hours = <<183/3=61>>61 mph.

To determine whether Theo can drive 118 miles in 2 hours, we can calculate the time it would take him to travel 118 miles at his speed of 60 mph: 118 miles / 60 mph = <<118/60=1.97>>1.97 hours.

Since 1.97 hours is less than 2 hours, Theo could drive 118 miles in 2 hours.

To determine whether Lex can drive 118 miles in 2 hours, we can calculate the time it would take him to travel 118 miles at his speed of 61 mph: 118 miles / 61 mph = <<118/61=1.93>>1.93 hours.

Since 1.93 hours is less than 2 hours, Lex could also drive 118 miles in 2 hours.

Therefore, both Theo and Lex could drive 118 miles in 2 hours.

Answer:

28

Step-by-step explanation:

Determine which integer in the solution set will make the equation true. t − 42 = −14 {−56, −28, 3, 28}

replace 28 for t:

t − 42 = −14

28 − 42 = −14

−14 = −14

Answer:

  28

Step-by-step explanation:

You want the value of t that satisfies t − 42 = −14.

The solution to this 1-step linear equation is to add the opposite of the unwanted constant (-42).

Adding 42 to both sides of the equation gives ...

  t -42 +42 = -14 +42

  t = 28

The integer that makes the equation true is 28.

The given statement " All else being equal, the further the t statistic falls from 0, either in the positive or negative direction, the more likely it is that the difference between two population averages is statistically significant. " is true.

The term t statistics refers the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error.

Here we have the statement All else being equal, the further the t statistic falls from 0, either in the positive or negative direction, the more likely it is that the difference between two population averages is statistically significant.

And we need to identify whether the statement is true or not.

As per the definition of t statistics, we have identified that the t statistic falls from 0. which states that is goes on the negative direction.

Therefore, the more likely it is that the difference between two population averages is statistically significant.

So, the statement is correct.

Answer: S

Step-by-step explanation:

The required value of "a" would be 3.

Perpendicular lines are two lines that cross one other and create a 90-degree angle.

As per the question, we have

Line m has the equation y = −13x − 2

Here slope of line m = -13

The slope of the given line m will be -13,

Line k passes through the points (0,4) and (9, a).

The slope of line k = (a - 4)/(9-0)

The slope of line k = (a - 4)/9

Given line m and line k are both perpendicular to each other,

We know that two lines are perpendicular if the product of their slopes is -1.

So,  -13 × (a - 4)/9 = -1

⇒ -13a + 52 = 13

⇒ 13a = 52 - 13

⇒ 13a = 39

⇒ a = 39/13

⇒ a = 3

Therefore, the required value of "a" would be 3.

The null hypothesis of a test always predicts no effect or no association between variables, but the alternative hypothesis reflects the effect or relationship that your research predicts.

Hypothesis;-

A put forward explanation for a phenomenon is called a hypothesis (plural: hypotheses).

A hypothesis cannot be called a scientific hypothesis unless it can be tested using the scientific process. Observations from the past that cannot be fully explained by the body of knowledge at this time often serve as the foundation for scientific ideas.

A scientific hypothesis is distinct from a scientific theory, despite the fact that the phrases "hypothesis" and "theory" are sometimes used interchangeably.

A working hypothesis is a theory that has been accepted provisionally and is put forth for further investigation[1], beginning with an educated guess or way of thinking.

Answer:

d) y = -3x-3

e) y = -3x - 1

f) y = -3x + 2

Step-by-step explanation:

Knowledge Needed:

Slope-Intercept Form: y = mx + b

y and x stay as variables so you can solve for the intercepts and graph.

m is the slope, or the constant amount that the y-value on a line changes when the x-value increases by 1.

b is the y-intercept, or when t he line has an x-value of 0.

When lines are parallel, they have the same slope.

Question

d)

Examine the line: At what y-value does the line have a x-value of 0?

y-value: -3

Alternatively, you could also solve be getting a set of points on the line and plugging in.

(1,0)

Our equation for line d:

y = -3x - b

0 = -3(1)  - b

0 = -3 - b

0 + 3 = -3 + 3 - b

3 = -b

b = -3

d) y = -3x-3

e)

Repeat the same steps.

y-intercept: -1

Because they are parallel, they have the same slope.

e) y = -3x - 1

f)

Repeat the same steps.

y-intercept: 2

Because they are parallel, they have the same slope.

f) y = -3x + 2

Height, length, and width are the three dimensions that all of the places we dwell and things we utilize on a daily basis have.

Height, depth, and other dimensions are examples of dimensions.

The dimensions of a line, a square, and a cube are each one, two, and three, respectively.

However, we consider the Universe to have one temporal dimension and three spatial dimensions (north-south, east-west, and up-down).

So, we have the area (A):

A = (54 – 2x)x

A = 54x - 2x²

Differentiate to obtain: dA/dX = 54 - 4x

We shall differentiate and equate to zero for a maximum Area, so dA/dx = 0.
