Fred needs 12 meters of ribbon to wrap each gift. He has a spool of ribbon that contains 18 feet of ribbon. One meter is equivalent to approximately 3 feet. How many gifts of same dimension can he wrap using the spool of ribbon
Answer:
5
Step-by-step explanation:
The computation of the gits is shown below;
Given that
The ribbon which is used to wrap the gift = 1.2m
The ribbon that he spoiled = 18feet
based on the above information
As we know that 3feet = 1m
1foot = 1 ÷ 3 m
Now
18feet = 1 ×18 ÷ 3
18 feet = 6m
Now,
gift can be packed = 6 ÷ 1.2
= 60 ÷ 12
= 5
suppose that a data set has an approximately symmetrical distribution, with one outlier. what could you do if you wanted to use the mean and standard deviation to characterize the data?
Answer:
The median is known as a measure of location; that is, it tells us where the data are. As stated in , we do not need to know all the exact values to calculate the median; if we made the smallest value even smaller or the largest value even larger, it would not change the value of the median. Thus the median does not use all the information in the data and so it can be shown to be less efficient than the mean or average, which does use all values of the data. To calculate the mean we add up the observed values and divide by the number of them. The total of the values obtained in Table 1.1 was 22.5

7. Set up the trig equation with the correct values plugged in that you would use to solve for x. *
sin (29) = 8/x
sin (29) = x/8
cos (29) = x/8
tan (29) = 8/x
Answer and Step-by-step explanation:
To solve for x, we would use the Sine trig function.
[tex]sin(theta) = \frac{opposite"side}{hypotenuse}[/tex]
Plug in the values.
[tex]sin(29) = \frac{x}{8}[/tex] is the answer.

Kong took 15\%15%15, percent fewer seconds than Nolan took to complete his multiplication timed test. Kong took 858585 seconds.
How many seconds did Nolan take?
kong: 15% 15x100=1,500
Nolan:85 seconds 85x2=170
then when you multiple kong by 15 and 100 it gives you 1,500 however nolan did of the seconds 85x 2 gives you 170 . in conclusion Nolan did 15x2=30 . which means Nolan did 30 seconds.

Ali swam 0.5 squared kilometers in January and 0.3 cubed kilometers in February. What is the total distance he swam for both months? 1.9 kilometers 0.277 kilometers 0.727 kilometers 0.8 kilometers
Answer:
d = 0.277 km
Step-by-step explanation:
Distance covered in January = 0.5² km
The distance covered in February = 0.3³ km
We need to find the total distance he swam for both months. It can be calculated by finding their sum. So,
[tex]d=0.5^2+0.3^3\\\\d=0.25+0.027\\\\d=0.277\ km[/tex]
So, he swam 0.277 km for both months. Hence, the correct option is (b).

Find the slope
Answer:
slope = 4/11
Step-by-step explanation:
To find the slope, use delta y/ delta x
(4,6) (-7,2)
(2-6)/(-7-4)
(-4)/(-11)
slope = 4/11
Let m = slope
m = difference of y-values divided by the difference of x-values.
m = (2 - 6)/(-7 - 4)
m = -4/-11
m = 4/11
17. A line passes through the points (0,5) and (3, 11). Which of the following is the value of y when this line passes through x = 10? (1) 16 (3) 21 (2) 19 (4) 25
Answer:
(4) 25
Step-by-step explanation:
First, find the slope using rise over run:
(y2 - y1) / (x2 - x1)
Plug in the points:
(11 - 5) / (3 - 0)
6 / 3
= 2
The y intercept, (0, 5), has already been given. Using the equation y = mx + b, plug in the slope and y intercept to create the equation:
y = mx + b
y = 2x + 5
Now, plug in 10 as x to find the value of y:
y = 2x + 5
y = 2(10) + 5
y = 20 + 5
y = 25
So, the correct answer is answer choice 4, 25.
The value of the variable 'y' at x = 10 will be 25. Then the correct option is D.
What is the equation of a line passing through two points?Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).
Then the equation of the line is given as,
[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]
A line passes through points (0,5) and (3, 11). Then the equation of the line is given as,
(y - 5) = [(11 - 5) / (3 - 0)](x - 0)
y = 2x + 5
If the value of the variable 'x' is 10, then the value of the variable 'y' is calculated as,
y = 2(10) + 5
y = 20 + 5
y = 25
The value of the variable 'y' at x = 10 will be 25. Then the correct option is D.

If gas costs $2.85 per gallon, how many whole gallons of gas could you buy with $30.00?
Answer:
11
Step-by-step explanation:
We can buy 10 gallons of gas with $30, whose unit price is $2.85.
What is unit rate?The rate calculated for one quantity of something is called unit rates.
Given that, the gas costs $2.85 per gallon, we need to find how many whole gallons of gas could you buy with $30.00.
Let the x gallons cost $30.00
Therefore,
2.85x = 30
x = 30 / 2.85
x = 10.52
x ≈ 10
Hence, we can buy 10 gallons of the gas from $30.

Answer:
the answer is c 1.2
Step-by-step explanation:
to calculate the iqr you have to do the following:
q3 - q1 = answer
4.5 - 3.3 = 1.2
The IQR(interquartile range) for the distribution of the song length is 1.2.
What is interquartile range(IQR)?Interquartile range gives information on the spread of the middle half of your distribution.
Mathematically, the interquartile range can be represented as follows:
IQR = Q₃ - Q₁
where
Q₃ = 4.5
Q₁ = 3.3
Therefore,
IQR = 4.5 - 3.3
IQR = 1.2
Therefore, the interquartile range is 1.2.
