Answers
Explanation:
Refer to the table below. I've added a third row where I multiplied each x value with its corresponding frequency value f. We can refer to this row as the xf row.
Once we know the xf values, we add them up to get 245.
We'll then divide that result over the sum of the frequency values (add everything in the second row). The sum of the frequency values is 39.
So the mean is approximately: 245/39 = 6.282051 which rounds to 6.282
Notice that this mean value is fairly close to the x value which has the highest frequency.

A ball is thrown upward and outward from a height of 8 feet. The height of the ball, f(x), in feet, can be modeled by
f(x) = -0.1x² +0.6x+8
where x is the ball's horizontal distance, in feet, from where it was thrown. Use this model to solve parts (a) through (c).

what is the answer and steps to 18(2 − 1) ÷ 3 + 4
Answers
The answer is 10, by using pemdas you can just either add, subtract, multiply or divide.
10
Hi! When you see problems like this, always refer to PEMDAS!
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Also note that you go from left to right and parenthesis is always first!
18(2-1)÷3+4
Start with the parenthesis and subtract 2 from 1. That'll leave you with 1.
18(1)÷3+4
Next is multiplication since there are no exponents. Multiply 18 by 1. That'll leave you with 18.
18÷3+4
Now, divide 18 from 3. That'll leave you with 6.
6+4
Finally, you may add the final two. 6 plus 4 is 10.
With that being said, the correct answer is 10.

The value of a certain SUV, in dollars, x years from its model year can be predicted by the exponential function shown in the table.
x| 0| 1| 2| 3| 4| 5|
g(x)| 21,000| 18,690| 16,634.10| 14,804.35| 13,175.87| 11,726.52|
How much more will the SUV be worth than the car 5 years after their model years? Round your answer to the nearest cent.
Answers
Using the exponential function, it is found that the SUV is worth $3,253.36 less than the car after 5 years.
The exponential function for the value of the SUV, after x years, is given by:
[tex]f(x) = 17000(0.87)^x[/tex]
Hence, after 5 years, the value is:
[tex]f(5) = 17000(0.87)^5 = 8473.16[/tex]
From the table, after 5 years, the car is worth $11,726.52.
11726.52 - 8473.16 = 3253.36.
The SUV is worth $3,253.36 less than the car after 5 years.

(b) A sum of money was to be shared among three friends Keisha, Tracey, and Kerry-Ann, in the
ratio 7:9:11 respectively. If Kerry-Ann received $3,300.00, find the sum of money that was
between the three friends.
Answers
The sum of the money that was between the three friends is $8100.
Let x represent the amount of money given to the three friends to share.
Keisha, Tracey, and Kerry-Ann shared the money in the ratio 7:9:11 respectively.
Since Kerry-Ann received $3300, hence:
(11/27) * x = 3300
11x/27 = 3300
x = $8100
The sum of the money that was between the three friends is $8100.
