As the train’s engineer, Erin guided the train on a 64 mi run, which took 1.7 h. She then stopped on a side rail to let a second train pass. She then continued another 80 mi, which took 1.9 h.What was the train’s average speed for the entire run?
Answers
64+80=144 miles
let's also calculate the complete time: (we can ignore the waiting time here, since they also didn't move during this time:
1.7h+1.9h=3.6 hours.
And now we only need to divide the distance per time:
So the correct answer is 40 miles per hour!

Answers
Answer:
The statements i) and iii) are best supported by the dot plot.
i) The range of the number of miles Amanda skated in
August is less than the range of the number of miles she
skated in July.
iii) The mode of the number of miles Amanda skated in July
is equal to the mode of the number of miles skated in
August.
Step-by-step explanation:
i) The range of the number of miles Amanda skated in August is 1 to 3
The range of the number of miles Amanda skated in July is 1 to 4
The range of the number of miles Amanda skated in August is less than the range of the number of miles she skated in July.
This is a true statement and this is the correct answer
ii)The distribution of data for the month of July is almost symmetrical but the
data in August is not.
The range of the number of miles Amanda skated in August is less than the range of the number of miles she skated in July.
This statement is not true.
iii)The mode of the number of miles Amanda skated in July is 1.
The mode of the number of miles Amanda skated in August is 1.
The mode of the number of miles Amanda skated in July is equal to the mode of the number of miles skated in August.
This is also a true statement.

Answers
The correct order from least to greatest among the given sets is:
H. V16, 4.2, 45, V18
The correct order among the given sets of numbers is H: V16, 4.2, 45, V18.
Let's explore this order further:
V16: This represents the square root of 16, which is 4. So, V16 is equal to 4.
4.2: This is a decimal number and is the smallest in the set.
45: This is a whole number, larger than 4.2.
V18: This represents the square root of 18, which is approximately 4.24. Therefore, V18 is greater than 4.2 but smaller than 45.
The correct order, from least to greatest, is 4.2, V16 (4), 45, V18 (approximately 4.24).
This order is consistent with the values of these numbers.
It's important to note that square roots like V16 and V18 are essentially values between the whole numbers 4 and 5, with V18 being slightly closer to 4.
So, they fall between 4 and 4.2 in terms of magnitude, which is why they are in the middle of the ordered set.
H. V16, 4.2, 45, V18

tr to isolate the unknown by itself
3x+3=12
minus 3 both sides
3x+3-3=12-3
3x+0=9
3x=9
divide by 3
x=3
x/4+4=8
minus 4
x/4=4
multiply 4
x=16
To solve these type of equations, we need to apply the inverse operation to both sides of the equation. Next, we'd isolate the variable.
Here's how it's done:
3x + 3 = 12
- 3 -3
Notice, we subtracted 3 from both sides.
3x = 9
3x/3 = 9/3
x = 3
Now for the other:
x/4+4=8
- 4 -4
8 - 4 = 4
x/4 = 4
x/4 * 4/1 = 4 * 4
x = 16
We're officially done:
1st one: x = 3
2nd one: x = 16

Answers
Answer:
option: A and Option: B are correct.
Step-by-step explanation:
We are given a scatter plot we are asked to find which of the given statements hold true such that it's ranges describe the cluster in the scatter plot.
Clearly from the scatter plot we could see that:
The most of the points are between 6-12 years of experience in the scatter plot.
also the earnings are between $40,000 and $60,000 that covers most of the data.
Hence, option A. ( A. between 6 and 12 years of experience) and Option B ( B.
between $40,000 and $60,000 ) are correct.
and
D. between 10000 and 60000
