A council reviews the number of bedrooms in 40 houses located in the same area. The table shows the information gathered. Find the modal average number of bedrooms. Work out the mean number of bedrooms
The modal average number of bedrooms is 3, while the mean number of bedrooms is 2.825.
What is Mean?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.

Write the SLOPE INTERCEPT FORM of the equation of the line parallel to y=23x+19 through the point (6, 2). First to answer correctly gets brainliest!
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

If a train travels 165 km in 1 hour 50 minutes at a constant speed, calculate how far it could travel in 3 hours
The train travel 270 Km in 3 hours.
What is speed- distance?Speed = Distance/Time Distance = Speed X TimeTime = Distance / SpeedGiven:
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

D.Micah's sample will be representative because anyone can surf at Breakers Point.
Answer:
B. The population for the survey is all people who surf at Breakers Point.
D.Micah's sample will be representative because anyone can surf at Breakers Point.
Step-by-step explanation:
hope it helps
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.
What is random sampling?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.
