The statements that are true are:

The population for the survey is all people who surf at Breakers Point.

Micah will not get a representative sample.

Options B and C are the correct answer.

It is the way of choosing a number of required items from a population given.

Each item has an equal probability of being chosen.

We have,

A.

Micah will obtain a random sample by talking to as many surfers as possible.

This statement is not necessarily true as Micah may not be able to talk to all the surfers at Breakers Point during the time frame mentioned. Additionally,

Randomly selecting surfers would result in a better representation of the population.

B.

The population for the survey is all people who surf at Breakers Point.

This statement is true, as the population of interest is the surfers at Breakers Point.

C.

Micah will not get a representative sample.

This statement is also true, as the survey is conducted only between 8:00 A.M. and 12 P.M, which may not be representative of all surfers at Breakers Point.

Additionally, there may be bias in the sample if Micah only surveys surfers at a certain location or time period.

D.

Micah's sample will be representative because anyone can surf at Breakers Point.

This statement is not necessarily true as not all surfers may surf at the same time or location, or have the same level of experience or preference for surfboard style.

Thus,

The population for the survey is all people who surf at Breakers Point and

Micah will not get representative sample statements are true.

Answer:

y = 23x - 136

Step-by-step explanation:

Since the lines are parallel, they have the same slope. So, the slope of the new line is 23 as well.

Now we have: y = 23x + b

plug in the points that are on this line (6,2) :

2 = 23 x 6 + b

2 = 138 +b

-136 = b

Line: y = 23x - 136

The train travel 270 Km in 3 hours.

Given:

Distance = 165 Km

Time= 1 hour 50 min

        = 1 5/6 hour = 11/6 hour

So, speed= distance/ time

speed = 165 / (11/6)

           = 165 x 6/11

           = 15 x 6

          = 90 Km/ h

Then, In three hour the train travels

Distance= 90 x 3

Distance= 2700 Km

Answer:

d + m = 100

12d + 10m = 1120

Step-by-step explanation:

d = 60

m = 40

Answer: 60 kg dark chocolate, 40 kg milk chocolate

Step-by-step explanation:

Okie soooo

Let's name the variables (which they did for us lol)

d = kg of dark chocolate and m = kg of milk chocolate

He needs 100 kg of chocolate

d + m = 100

and he wants to spend 1120 when dark chocolate costs $12/kg and milk chocolate costs $10/kg

12d + 10m = 1120

Now we solve the system (I shall use elimination method)

Multiply the first equation my -10

-10(d + m) = (100)(-10)

which becomes

-10d - 10m = -1000

12d + 10m = 1120 (rewrite the second equation)

------------------------- (add the two equations together)

2d = 120

d = 60

now substitute d into either equation

60 + m = 100

m = 40

60 kg dark chocolate

40 kg milk chocolate

The modal average number of bedrooms is 3, while the mean number of bedrooms is 2.825.

A mean is an arithmetic average of a set of observations. it is given by the formula,

Mean = (Sum of observations)/Number of observations

A.) The modal average number is a mode of a given data set. Now, if the mode of the given data is needed to be taken then we need to observe the row that has the highest frequency.

Therefore, the modal average number of bedrooms is 3.

B.) The mean number of bedrooms can be found as shown below.

Mean number of bedrooms = (1×5 + 2×10 + 3×15 + 4×7 + 5×3)/40

                                               = (5 + 20 + 45 + 28 + 15)/40

                                               = 113/40

                                               = 2.825

Hence, the modal average number of bedrooms is 3, while the mean number of bedrooms is 2.825.
