Aye please help! It is a late assignment I missed math class so please helppp!
Answer:
$3
Step-by-step explanation:
When doing estimation, you would want the estimated amount to be rounded off to a number that can be divisible by the question, which in this case is 4. Thus, I will be rounding $11.87 to $12.
11.87 ≈ 12
Amount each friend will pay ≈ 12÷4
= 3
Can someone please do this?

A truck is moving at a fixed speed. e Find the speed of the truck. Write a formula that connects D and T. What is the coefficient of variation k?
Answer:
1. The speed of the truck, S = D/T.
2. The formula that connects D and T is: S = D/T.
3. The coefficient of variation, k, is the ratio of the standard deviation to the mean speed.
Step-by-step explanation:
a) The speed of a truck at a fixed speed is given as the distance covered by the truck divided by the time it takes the truck to cover the said distance. This implies that speed is a function of distance and time. However, this formula represents the mean speed. There are variations in speed.
b) If the truck covers a distance of 60 kilometers, for example, under 3 hours, we can conclude that the speed is 20 kilometers per hour (60/3) or 20 km/hr.

situation: the ratio of my friends that like basketball to the ratio of my friends that don’t like basketball is 41:30. This means that 41 out of my 71 friends like basketball. 57.74% of my friends like basketball and 42.26% of my class doesn’t like basketball.
question: if the ratio stayed constant for the whole school, what would your equivalent ratio be with a new total of 310 total people?
Answer:
17.9:13
Step-by-step explanation:
I know this because in order to find the percentage of 310, you must mutiply 310 by the percentage.
The number of students who like basketball:
310 x 0.05774 = 17.9
The number of students who don't like basketball:
310 x 0.04726 = 13
Hope this helps! :)

Last month, Jason’s dog drank about 728 ounces of water and his cat
drank about 252 ounces of water.
If Jason’s dog continues to drink this amount, how many ounces of water will he have consumed after 6 months? Show your work in the box below.
Answer:
131,040
Step-by-step explaination:
There is around 29-31 days in a month, so if you just round it's around 30 days a month.
30×6= 180 (days)
180×728= 131,040 ounces
jasons dog would drink 131,040 in 6 months.

Suppose it is certain that an earthquake will occur someday. What is the probability (to the nearest percent) that it will occur while you are at work? Assume you are at work 8 hours per day, 240 days per year.
Answer:
22%
Step-by-step explanation:
Given that:
Number of hours at work daily = 8 hours
Number of days at work per year = 240
Total number of hours at work per year = Number of hours at work daily [tex]\times[/tex] Number of days at work per year
Total number of hours at work per year = 8 [tex]\times[/tex] 240 = 1920 hours
Total number of days in an year = 365
Total number of hours per day = 24
Total number of hours in an year = 24 [tex]\times[/tex] 365 = 8760
Here, to find the probability that the earthquake will occur while the person is at work, we actually have to find the fraction of number of hours at work to the total number of hours in an year.
Therefore, the required probability is:
[tex]\dfrac{1920}{8760} \approx \bold{0.2191}[/tex]
Therefore the probability to the nearest percent is: 22%
To rent a certain meeting room, a college charges a reservation fee of $36 and an additional fee of $5.60 per hour. The film club wants to spend at most $58.40
on renting the meeting room.
What are the possible amounts of time for which they could rent the meeting room?
Use t for the number of hours the meeting room is rented, and solve your inequality for 1.
Answer:
t≤4
Step-by-step explanation:
58.40≥36+5.60t
Solve like any equation
58.40≥36+5.60t subtract 36 from both sides
22.40≥5.60t divide by 5.60
t≤4
convert 6 2/5 to a percent?
A) 6.4%
B) 64%
C) 640%
D) 6,400%
Answer:
C) 640%
Step-by-step explanation:
6 2/5
Convert it to an improper fraction -
6 2/5 = 32/5
Convert the improper fraction to a decimal -
32/5 = 6.4
Multiply 6.4 by 100
= 640%
Hope this helps :)
Answer: Oooohhhh, I knew the answer the answer is 640%.
Step-by-step explanation: So start by separating the parts: [tex]6+\frac{2}{5}[/tex],
Then I know that [tex]\frac{2}{5} = 2/5[/tex],
∴ [tex]6\frac{2}{5} = 6+(2/5)[/tex],
Then I use The Long Division for 2 divided by 5, so I have [tex]6+0.4=6.4[/tex],
And last but not least is onverting our number to a percentage: [tex]6.4*10=640%[/tex] (Rounded to a Max of 2 Decimal Places.), so I hope this formula could be helpful, but if you have struggle to convert the mixed number fraction to percentage, please ask me, okay? :)

7 identical taps can fill 3 identical tanks in 45 min. How long it will take 5 of the taps to fill one of the tanks?
Answer:
21 minutes
Step-by-step explanation:
Given that:
7 identical taps fill 3 identical tanks in 45 minutes
Since the taps and tanks are identical :
Hence, the 7 taps can fill 1 tank in :
45 /3 = 15 minutes
Therefore, 1 tap will fill 1 tank in :
7 tap = 15 minutes
1 tap = (15 * 7) = 105 minutes
Hence, 5 taps will fill 1 tank in :
105 minutes / 5
= 21 minutes

sin(5x)
Step-by-step explanation:
Recall that the half angle identity relates the sine of half an angle to the square root of one minus the cosine of the angle as shown below:
[tex]sin(\frac{\theta}{2} )=+/-\sqrt{\frac{1-cos(\theta)}{2} }[/tex]
therefore, in our case:
[tex]sin(5\,x )=+/-\sqrt{\frac{1-cos(10\,x)}{2} }[/tex]
so, make sure you type the expression : "sin(5x)" in the provided text-box.
The number 1.255 is an example of a terminating or repeating
decimal number?
Answer:
Terminating
Step-by-step explanation:
Since the number ends exactly after 3 decimal places, it is a terminating decimal number.
On the other hand, repeating decimal numbers are numbers such as 2.33... or 8.66... that repeat the number forever.
So, the number 1.255 is terminating.

What's the axis of symmetry of y = 3x2 - 6x + 4
Answer: The axis of symmetry = 1
That's a vertical line passing through 1 on the x-axis
Step-by-step explanation: From standard form, ax² + bx + c
Use the values of a and b in the equation x = -b/2a to find s, the axis of symmetry.
x = -(-6)/2(3)
x = 6/6
x = 1
The required axis of the symmetry of the given parabola is x = 1.
Given that,
To determine the axis of symmetry of y = 3x² - 6x + 4.
A parabola is a cross-section cut out of the cone and represented by an equation.
Here,
The axis of symmetry of a parabola is given by -b/2a
Now. from the given parabolic equation y = 3x² - 6x + 4. we have a = 3 and b = 6.
Substitute the value in the symmetry equation
Axis of symmetry, x = -(-6)/2(2)
x = 1
Thus, the required axis of the symmetry of the given parabola is x = 1.

What is linear regression line?The connection between the independent (x) and dependent (y) variables in the graph can be graphically represented using regression lines.
In a linear model, the terms are added rather than multiplied, divided, or provided as a non-algebraic function, as has been the case thus far in this section. Analysis of experimental, monetary, and biological data as well as complex system prediction are both possible using linear modelling.
A statistical technique used to build a linear model is called linear regression. The model explains how one or more independent variables Xi relate to a dependent variable y (also known as the response) (called the predictors). The distance between each data point and the regression line is called a residual.
Given data ,
Let the linear regression line be represented as A
Now , the value of A is
Let the first coordinate on the graph be P ( 1 , 5.5 )
Let the second coordinate on the graph be Q ( 2 , 6 )
And , the data plots on the graph represents a curve or parabolic equation
So , it is a quadratic equation
Hence , the data plot of the regression line is quadratic

6 friends all use $2 off coupons to buy themselves movie tickets. They spend a total of $42 Write the equation
Answer:
(C / n) + 2
Step-by-step explanation:
Amount spent (C) = 42
Number of friends (n) = 6
Coupon on ticket = $2
Original price of ticket will be :
Cost per coupon ticket = (Total amount spent / number of friends)
(Total amount spent / number of friends) + coupon on ticket
= (C / n) + 2
= (42 /6) + 2
= 7 + 2
= 9
