The value of c that makes the equation true is: c = -13/21.
What is an Equation?An equation is a mathematical statement whose values on the right and left sides are equal.
Given:
c + 15 = 23c + 2 − 43c
Find the value of c
c + 15 = -20c + 2
c + 20c = -15 + 2
21c = -13
c = -13/21
Thus, the value of c that makes the equation true is: c = -13/21.

The value of c which makes the equation c + 15 = 23c + 2 − 43c true is –13/21
Data obtained from the question c + 15 = 23c + 2 − 43c Value of c =? How to determine the value of cc + 15 = 23c + 2 − 43c
The value of c in the expression above can be obtained as illustrated below:
c + 15 = 23c + 2 − 43c
Collect like terms
c – 23c + 43c = 2 − 15
21c = –13
Divide both side by 21
c = –13/21

How many litres of fuel will a car use to travel 450 km if its fuel consumption is 6,8 km/l?
Step-by-step explanation:
are you sure the fuel consumption is given by 6,8 km/l ?
normally it is given by l/100km.
but ok, let's assume this is correct.
it would mean the car can drive 6,8 km with every liter of fuel in the tank.
how many liters will the car need to go 450 km ?
well, as many liters as 6,8 fits into 450 :
450/6,8 = 66.17647059... liters
this is not a very fuel efficient car ...

dave builds a crate to hold veggies. the volume of the crate is 48 cubic feet. the base area of the crate is 16 square feet. what is the height of the crate?
16 sq ft = 2 ft x 8 ft
4 ft x 4 ft
but..
4 ft x 4 ft x 4 ft = 64 cubic ft
So 4 cannot be the height of this crate.
h represents the height of the crate (defined variable)
2 ft x 8 ft x h = 48 cubic ft
16h = 48
h = 3 ft
The height of the crate is 3 feet.
Check:
2 ft x 8 ft x 3 ft = 48 ft ³

Which value for R in the table would most likely indicate an association between the conditional variables? 0. 09 0. 10 0. 13 0. 79.
The value for R in the table which is most likely to indicate an association between the conditional variables is 0.79.
What is an association between the conditional variables?The association between the conditional variables, exist when the relative frequencies between the two variables are not similar.
The more the difference in the values shows the stronger the association between two.
The table given in the problem is attached below. The given option for the R value in the table is, 0.09, 0.10, 0.13, and 0.79.
As it is known that the bigger the difference, gives the stronger the association. Here, the R value with 0.79 is the most opposite to the value above the R.
Hence, the value for R in the table which is most likely to indicate an association between the conditional variables is 0.79.

a can be a triangle (obtuse)
b can be a triangle (acute)
Step-by-step explanation:
Let 1995 correspond to x=0. Let b be the ratio between the population in 1995 and 1996. Determine an exponential function of the form y=a(b)^x to represent the population symbolically. Round to 3 decimal places.
The table is an illustration of an exponential function
The equation of the table is [tex]y = 148 * 0.997^x[/tex]
How to determine the equation of the tableGiven that 1995 corresponds to x = 0, then
The initial value (a) of the function is:
a = 148.0
The equation of the function is:
[tex]y = ab^x[/tex]
When x= 1, we have:
[tex]147.6 = ab^1[/tex]
[tex]147.6 = ab[/tex]
This gives
[tex]147.6 = 148b[/tex]
Divide both sides by 148
[tex]b = 0.997[/tex]
Hence, the equation of the table is:
[tex]y = 148 * 0.997^x[/tex]

What is the standard deviation around the regression line?.
Answer:
The standard deviation of the residuals calculates how much the data points spread around the regression line. The result is used to measure the error of the regression line's predictability.
Step-by-step explanation:
How do you find the standard deviation around the regression line?STDEV. S(errors) = (SQRT(1 minus R-squared)) x STDEV. S(Y). So, if you know the standard deviation of Y, and you know the correlation between Y and X, you can figure out what the standard deviation of the errors would be be if you regressed Y on X.
What does standard deviation tell you?A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

The first step of finding the percent tip, we must find how much tip she paid:
Tip = $38.61 - $33 = $5.61
To find the percent tip, we must divide the tip amount by the amount she paid before the tip
$5.61 / $33 = 0.17 --> 17%
Thus the percent tip is 17%
