Answer:
x<=119
Step-by-step explanation:
If it's no greater that the mean is 120 seconds, then the sum of the seconds should be 600. 600-118-129-120-114=119
So x should be less or equal to 119.

Answer:
Step-by-step explanation:
Nine cyclists were each asked the distance in miles they biked last week.
Their responses are given below.
Complete the grouped frequency distribution for the data.
In the distribution, the frequency of a class is the number of distances in that class.
(Note that we are using a class width of 6.)
The frequency for 2 to 7 is 3
The frequency for 8 to 13 is 4
The frequency for 14 to 19 is 2
The grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.
Given that, nine cyclists were each asked the distance in miles they biked last week. The distance travelled by 9 cyclists is 16, 8, 2, 6, 8, 11, 9, 15 and 7.
We need to complete the grouped frequency distribution for the data.
What is the grouped frequency distribution?In this type, the data is arranged and separated into groups called class intervals. The frequency of data belonging to each class interval is noted in a frequency distribution table. The grouped frequency table shows the distribution of frequencies in class intervals.
Now, the frequency distribution for the given intervals is as follows:
That is, for intervals 2 to 7 the frequency is 3.
For intervals 8 to 13 the frequency is 4.
For intervals 14 to 19 the frequency is 2.
Therefore, the grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.

The total change in the outdoor temperature over 6 hours was -21°F
What was the mean change in temperature per hour?
₋₋₋₋₋₋₋₋ °F per hour
Answer:
-3.5
Step-by-step explanation:
As there was a total change of -21, that would be the first part of your equation:
-21
As 6 hours had passed and you are trying to find the mean, your equation would now be:
-21 ÷ 6 = ?
Now you can solve the equation, and the answer is -3.5°F per hour.
The mean change in temperature per hour is -3.5 °F.
what is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
The total change in the outdoor temperature over 6 hours was -21°F
So, in one hour the mean change in temperature
= -21/6
= -3.5 °F
Hence, the mean change in temperature per hour is -3.5 °F.

The school band has a goal of raising $800 for some new uniforms. If they have raised $512 so far, what percent of their goal have they raised?
Answer: 64%
Step-by-step explanation:
The band needs $800 for new uniforms and of that, they only raised $512.
Set up a proportion [tex]\frac{part}{total} = \frac{percentage}{100}[/tex]and plug everything you know in.
[tex]\frac{512}{800}[/tex] = [tex]\frac{x}{100}[/tex]
Solve for x by cross multiplying and dividing.
512 × 100 = 51200
51200 ÷ 800 = 64
x = 64
The school band has raised 64% of their goal already.
Answer:
The Answer would be 64%

−5.6x=−4
What is the solution to the equation?
Enter your answer as a simplified fraction in the box.
Answer: 0.714285
Step-by-step explanation:
The solution of the equation (-5.6 = -4) is (x = 5/7) and this can be determined by using the arithmetic operations.
Given :
-5.6x = -4
The following steps can be used in order to determine the solution to the equation (-5.6x = -4):
Step 1 - The arithmetic operations can be used in order to determine the solution to the given equation.
Step 2 - Write the given equation.
-5.6x = -4
Step 3 - Add 4 on both sides in the above equation.
-5.6x + 4 = -4 + 4
-5.6x + 4 = 0
Step 4 - Add 5.6x on both sides in the above expression.
-5.6x + 4 + 5.6x = 5.6x
4 = 5.6x
Step 5 - Divide 4 by 5.6 in the above expression.
[tex]x = \dfrac{4}{5.6}[/tex]
Step 6 - Simplify the above expression.
[tex]x = \dfrac{5}{7}[/tex]

so , i said 5/10x area = length * width A=10*x a= 10x
then i said you should divide , next i said 10x/5 10x in five sections is 2 in each q1 said area 10*x but x=2 so 10*2=20 is this correct?
Write an expression to represent the perimeter of the figure below.
Step-by-step explanation:
A perimeter is when you add up all of the sides
Here would be our equation
[tex]2(x+4)+2(2x-8)[/tex]
Answer: The expression for this would be 2(x+4) + 2(2x-8)
Step-by-step explanation:
This is because when we calculate perimeter, we add up all the sides. So, instead of doing (x+4)+(x+4), we can just do 2(x+4) and add up all sides. So, here’s the answer in simplest form!
