Answer:
x = 6
Step-by-step explanation:
Since the triangles are congruent, then corresponding sides are congruent, that is
QS = TV , substitute values
6x + 12 = 9x - 6 ( subtract 6x from both sides )
12 = 3x - 6 ( add 6 to both sides )
18 = 3x ( divide both sides by 3 )
6 = x
Answer:
x = 6
Step-by-step explanation:
x = ?
6x + 12 = 9x - 6
get the variables and numbers on different sides
6x + 12 - 6x = 12
9x - 6 + 6 = 9x
12 + 6 = 18
9x - 6x = 3x
3x = 18
divided each side by 3
3x / 3 = x
18 / 3 = 6
x = 6

what is the slope of -3/2 (3,1)
Answer:
y= -3/2
Step-by-step explanation:
formula: y-y1=m(x-x1)
y-1=-3/2(x-3)
y-1=-3/2x+9/2
y= -3/2x+11/2
this is now in y=mx+b form. m=slope /

Step-by-step explanation:
The slope is just x, and the y intercept will be one over from (1,-2) which is (0,-3), so -3 is the starting point.

The histograms below summarize the average travel time to work for random samples of 70
workers in the Los Angeles area and 61 workers in the New York City area.
(a) Briefly compare the distributions of travel times for these two regions.
(b) Suppose you wanted to make the point that typical travel time is longer in the New York City area than in the Los Angeles area. Which measure of center would you use? Justify
your answer.
Answer:
(a) The travel times of the Los Angeles workers have a higher variability than those of the New York City area and about 54 out the 70 Los Angeles workers take longer (over 20minutes) than the maximum travelling time for the New York City workers (18 minutes) when they travel to work
(B) (i) The percentage of workers that travel close to the maximum travel times given in the data of the two cities
(ii) Almost half of the New York City area workers spend between 40 and 100 minutes to work, while almost half (32) of the Los Angeles workers spend between 0 and 20 minutes to work every day
Step-by-step explanation:
The travel times for the 70 Los Angeles workers are;
Number of workers [tex]{}[/tex] Travel time
32 [tex]{}[/tex] 0 - 20 minutes
22 [tex]{}[/tex] 20 - 40 minutes
10 [tex]{}[/tex] 40 - 60 minutes
4 [tex]{}[/tex] 60 - 80 minutes
2 [tex]{}[/tex] 80 - 100 minutes
The travel times for the 61 New York City area workers are;
18 [tex]{}[/tex] 0 - 20 minutes
14 [tex]{}[/tex] 20 - 40 minutes
10 [tex]{}[/tex] 40 - 60 minutes
12 [tex]{}[/tex] 60 - 80 minutes

Workers in Los Angeles averagely take short time to reach to workplace than in New York.
Descriptive statistics like mode, IQR, skewness etc do care about how the data is more leaning on one side than other. That is why these types of measures are helpful here.
Given data includes:
For Los Angeles: 32, 22, 10, 4, 2 (skewed left)
For New York: (18, 14, 10, 12 ,7) (very slightly skewed left)
Part a.
Comparing the distributions of travel times for both of the regions:
Histogram of Los Angeles is more skewed to the left. (values like 32, 20 lies on the left, and 5, 2 on the right tail)
Histogram of New York, in comparison to the histogram of Los Angeles is not that skewed and lies approximately leveled but is slight skewed to left.
This hows that time taken by worker to travel in Los Angeles is averagely very short and count of workers taking longer time falls dramatically.
On the other hand, that above thing doesn't happen for workers in New York.
Part b.
Central measure "Mode" can be used here. The reason of choosing mode is that it focuses on frequency and gives weights to outliers too. Mean, on the other hand takes average of all values thus might forget the data of skewness.
The 3rd moment of measure of skewness can be used to measure the degree of skewness in both the data.
Inter Quartile Range is also useful since it will tell quartile to quartile measures which can help not loose the data of skewness.
So, the important thing that should be included in the measure we use to describe this data is to include the information of skewness of the graph.
Descriptive statistics like mean, standard deviation etc forget about skewness.
Descriptive statistics like mode, IQR, skewness etc do care about how the data is more leaning on one side than other. That is why these types of measures are helpful here.

Answer:
ductile
Step-by-step explanation:
Two other properties of copper that show it is a metal are malleable and ductile.
What is a metal?A metal is a substance that exhibits a better surface when properly processed, refined, or shattered, and transports warmth and electricity rather well. Generally speaking, metals generally malleable and ductile. These characteristics are the outcome of the metallic link that exists here between metal particles or atoms.
This suggests that the metal is ductile, malleable, and a superb energy and heat transmitter. It can be cleaned to a bright gloss and is smoother than zinc.
Unlike gold and silver, it is a member of group Ib on the regular chart. The chemical stability of copper is minimal. The metal when presented at room temperature will be in the solid phase.

How to find
range
mode
median
mean
Answer:
- Mode-The most repetitive number! - Median:The number in the MIDDLE when they are IN ORDER! - Mean- The AVERAGE OF ALL NUMBERS: You add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS! - Range - THE BIGGEST minus the Smallest!
branliest
Step-by-step explanation:
Range: To find the range we have find the smallest and highest numbers in a list or set. To find the range put the number on order, and then subtract the lowest number from the highest number.
Mode: To find the mode of a data set, we have to look the number that occurs most frequently in the set, and to find the mode we have to count how many times each number occurs.
Median: To find the median, first order the numbers from smallest to largest. Then find the middle number.
Mean: To find the mean we have to add up all the numbers, Then divide by how many numbers there are.
One cantaloupe costs $2. How many
cantaloupes can you buy for $6?
Answer:
3
Step-by-step explanation:
ignore this i need more letters lol have a good day
Answer:
You could buy 3 cantaloupes.
Step-by-step explanation:
So, you have $6. Now, what we would do is (O is 1 cantaloupe):
If O cost $2, do the following:
O O O O O
2 2 2 2 2
Now, lets count up til we get 6:
2 + 2 = 4; 4 + 2 = 6;
After you have done that step, count how many 2's you see in that equation. I see 3.
Therefore, you could buy 3 cantaloupes.

2. Will any of them taste different?

Be sure to use the vocabulary word: EQUIVALENT
RATIOS in your answer.
water
cups
1
4
12
0
18
Answer:
The answer to this question is given below in the explanation section.
Step-by-step explanation:
The table shows three different recipes. In this question, it is asked that will all the recipes taste same. To obtain the answer to this question, first, we measure the taste of each recipe in terms of calculating the ratio.
Water ............................. Cups
1 ............................. 3
4 ............................. 12
6 ............................. 18
1. The fraction of the first recipe is 1/3 so the ratio is 1:3(water to cup)
2. The fraction of the second recipe is 4/12
which can be simplified as 4/12=1/3 so the ratio is 1:3(water to cup)
3. The fraction of the third recipe is 6/18
which can be simplified as 6/18 = 3/9 = 1/3 so the ratio is 1:3(water to cup).
So based on the above answer, all recipes taste the same.
Answer 2:
No recipe taste different, all the recipe taste the same. Because all the recipe ratios are equivalent.

Answer:
The average rate of change from 0 to 20 years old is -2.
Step-by-step explanation:
Average rate of change means slope.
slope = y2 - y1 / x2 - x1
Pick any points between 0-20. They have given on the graph already (0, 112) and (20, 72) so plug it into slope equation.
112 - 72/ 0 - 20
40/-20
= -2
The average rate of change from 0 to 20 years old is -2.

Answer:
10 miles per hour
Step-by-step explanation:
60 / 6 = 10
Therefore, she is jogging 10 miles per hour.
Pretty sure this is running, not jogging.
The rate of jogging is 10 miles per hour
The calculation can be done as follows
Kelsey jogs a total of 60 feet in 6 seconds
The rate is = 60/6
= 10 miles/hour
Hence the rate in miles per hour to the nearest tenth is 10 miles per hour
