The table gives the scores of 6 students from a class of 25 in a competitive exam. The point estimate of the mean score for the students is _____-
. (Round off your answer to the nearest tenth.)

Answers

Answer 1
Answer:

Answer

593.3

Explanation

Mean is also called average. It represents the average mark of a given data.

For the question above, you to add all the marks of the students then you divide by the number of students.

Mean = (650+550+380+720+710+ 550)÷6

= 3,560 ÷ 6

=593.3333

Answer to the nearest tenth = 593.3
Answer 2
Answer:

The point estimate of the meanscore for the students is 593.34 if the number of observation is 6.

What is mean?

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

We know,

Mean = (sum of observation)/(number of observation)

Sum of scores = 650+550+380+720+710+550 = 3560

Number of observation = 6

Mean = 3560/6 = 593.33 = 593.34

Thus, the point estimate of the meanscore for the students is 593.34 if the number of observation is 6.

Answers

Answer:

the y value is 5. (-1,5)

Step-by-step explanation:

first you plug in -1 to the equation where the x is. f(-1)=-2(-1)+3. then solve with a calculator and you will get 5 as your y value. plug the equation in Desmos.

Is the following relation a function ?

Yes

No

Answers

Answer:

No

Step-by-step explanation:

For a relation to be a function, each value of x must map to exactly one unique value of y

Here x = 4 and x = 0 both map to y = 3

Thus the relation is not a function

Two cell phone companies have different rate plans. Runfast has monthly charges $25 plus $10 per gig of data. B A &D’s monthly charge is $18 plus 15 per gig of data. Your task is to determine under what circumstances each company has the better pricing. You will derive and solve a set of equations, graph those equations, and evaluate the meanings for these events. Don’t worry; I have a series of questions to guide you through the process. Good luck!Determine the equation for the monthly charges for Runfast and BA&D.

Runfast= $35 per month

BA&D= $33 per month

Answers

Given:
Runfast = 25 + 10g
BA&D = 18 + 15g

Runfast = 35 per month
35 = 25 + 10g
35 - 25 = 10g
10 = 10g
10/10 = g
1 = g

BA&D = 33 per month
33 = 18 + 15g
33 - 18 = 15g
15 = 15g
15/15 = g
1 = g

If g = 2;
Runfast = 25 + 10(2) = 25 + 20 = 45
BA&D = 18 + 15(2) = 18 + 30 = 48

Based on my computation, if the gig of data is only equivalent to 1g then BA&D is cheaper. However, if 2gig or above is used, then Runfast is cheaper.
