Looking at the means of these samples, which value is most likely to be the mean of the population from which the samples were taken? Sample Number Sample Mean 1 11. 8 2 12. 5 3 15. 1 4 14. 3 5 13. 2000 6 12. 9 10. 2 11. 5 12. 9 15. 4.

Answers

Answer 1

The most likely mean of the population from which the samples were taken is 12.96.

What is mean value?

The mean is the average or the most common value in a collection of numbers.

We are given the below data:

Sample Number              Sample Mean

1                                                 11.8

2                                                 12.5

3                                                 15.1

4                                                 14.3

5                                                 13.0  

6                                                 12.9

7                                                 10.2  

8                                                 11.5

9                                                 12.9

10                                                15.4

Now the most likely mean of the population can be found by finding the mean of given sample means. It is given below:

[tex]\rm Mean = \dfrac{11.8+12.5+15.1+14.3+13.2000+12.9+10.2+11.5+12.9+15.4}{10}\\\\ Mean =12.96[/tex]

Therefore, the most likely mean of the population from which the samples were taken is 12.96.

What divisor is represented by the synthetic division below? A vertical line and horizontal line combine to make a L shape. There are two rows of entries within the shape. Row 1 has entries 2, 10, 1, 5. Row 2 has entries blank, negative 10, 0, negative 5. Entry negative 5 is on the outside to the left of the shape, and a third row of entries is outside and below the shape. Row 3 has entries 2, 0, 1, 0. –5 5 x 5 x – 5.

Answers

One of the ways of dividing polynomials is by synthetic division

The divisor of the synthetic division is x + 5

How to determine the divisor of the division

From the question, we understand that:

Entry -5 is on the outside to the left of the shape

The entry represents the zero of the divisor.

Next, we set this entry to the variable (assume the variable is x)

So, we have:

[tex]x = -5[/tex]

Add 5 to both sides

[tex]x + 5= 0[/tex]

Hence, the divisor of the synthetic division is x + 5

Step-by-step explanation:

Demetrius is training for the same 1-mile race.
Demetrius ran at a constant speed of 7.5 miles per hour.
Yosef's progress is shown by the graph.
Who finished the mile first?

Answers

Yosef finished the mile in 9 minutes.

Distance = 1 mile

Demetrius' speed = 7.5 miles per hour

Demetrius' time = Distance/speed

= 8 minutes

Demetrius finished the mile first by taking 1 minute less than Yosef's finishing time.

Answer:

Demetrius wins the race by 7.5 minutes.

Step-by-step explanation:

We know that:

Demetrius = 7.5 miles = 60 minutesYosef = 1 mile = 9 minutes

Let's see how much time Yosef take in 7.5 miles.

Solution:

Yosef speed = 1 mile = 9 minutes=> 7.5 miles = 9 x 7.5 minutes=> 7.5 miles = 67.5 minutes60 minutes < 67.5 minutes

After working on this problem, we can conclude that Demetrius wins the race by 7.5 minutes.

A coke and a pretzel cost $2.08. If the coke is two dollars more than the pretzel, find the cost of the pretzel

Answers

Based on the information given, it should be noted that the cost of the pretzel is $0.04.

How to solve an equation.

Let the coke be represented by c.

Let the pretzel be represented by p.

Based on the information,

c = p + 2 ..... i

c + p = 2.08 ... ii

p + 2 + p = 2.08

2p + 2 = 2.08

2p = 2.08 - 2

2p = 0.08

p = 0.08/2 = 0.04

Therefore, c = 2 + 0.04 = 2.04

The probability can be expressed in the form of percentages as well as fractions form.

A local weather forecaster uses percentages to describe the chances of precipitation.

As we know, probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Let the chance of rain is 50% for tommorrow.

The probability for rain = 50%

We can write the above probability in the a form of fraction.

P = 50% = 50/100

P = 1/2

Thus, the probability can be expressed in the form of percentages as well as fractions form.

Answer #2 for me , all you have to do is graph the function which is y = 1/2 x - 5 and i completed the table .​

Answers

Answer/Step-by-step explanation:

The given function is linear. The curve will be a straight line.

Find two points. Plot them on a graph sheet. Join them with the help of a straight Line.

Given - y = 1/2 x - 5

Find the Y - intercept

At x=0;y=1/2(0)−5

(0,−5)  is one of the points.

For the other point we would normally find the X-intercept.

If we did that with this equation we would create a fraction. It may be little difficult to fix that point. So, instead, assign a value to y so that you get a whole number as x-co-ordinate.

In our case we shall assign +1 as y-co-ordinate.

At y=1;1=1/2x−5

1/2x−5=1

1/2x=1+5=6

x=6×2=12

(12,1) is another point.

Plot the points

(0,−5) and (12,1)

Join them with a straight line. You get the curve.
