Answer:
10
Step-by-step explanation:
(4 * 5) / 2 = 20 / 2 = 10
Answer:
Triangle R and triangle S are congruent triangles, so finding the area of triangle S would give us the area of triangle R.
The area of a triangle can be calculated as 1/2(bh), where b is the base and h is the height.
In this case, we have: 1/2(5)(4). This simplifies to 10.
So, the area of triangle R is 10 square meters.

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
Answers
Doing the mean, is the same as providing a weighted average of bedrooms, with the weights being the frequency a given number of bedrooms appears at. As such, I need to multiply each element of the first column with the respective element of the second column. For example, for 1 bedroom, I have 1 x5 = 5; for 2 bedrooms I have 2x10 =20; if we do this across all number of bedrooms, and then add it all up, we get 113. We then divide this 113, by the number of flats being surveyed ie 40. This gives an average (or mean) of 2.825
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.

Solve each problem. Round to the nearest tenth if necessary. Use 3.14 for π. What is the radius of a circle with a circumference of 15 cm? Show your work! I will be giving out brainliest!
Answers
Answer:
2.3
Step-by-step explanation:
First off, you start with the circumference formula which is 2(pi)r. Since we know our circumference, we can create the equation solving for r. so we have 15=2(pi)r. Now in order to solve for r, we need to transfer everything to the other side, meaning dividing by 2(pi). So 15/2(pi)=2(pi)r/2(pi). Since we are using 3.14 for pi, 3.14*2 is 6.28. 15/6.28 which is about 2.388 So the radius of the circle is 2.3 (rounded to the nearest tenth)

Answers
Answer:
$1.6
Step-by-step explanation:
We need to find the cost of 80 cm of copper pipe at $2 a metre.
Cost of 1 metre = $2
80 cm = 0.8 m
It means,
0.8 m = $2 × 0.8
= $1.6
So, the cost of 80 cm of copper pipe is equal to $1.6.

If a train travels 165 km in 1 hour 50 minutes at a constant speed, calculate how far it could travel in 3 hours
Answers
162 x 2= 330
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

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.

Answer:
x=72 degrees
Step-by-step explanation:
180-108=72
it is 180 because a straight angle is 180 degrees.
then you subtract 108, which is an alternate interior angle, to get 72, which is an alternate exterior angle.
Answer:
x=72
Step-by-step explanation:
Since the whole angle is 180 you have to do 180-108 which you get 72.
Then since x and 72 are vertical angles they have to be the same so x=72

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
