Answer:
first step.
times both sides by 4
that way your left side is no longer a fraction. then times both sides my x+3
that way you have no more fractions no simplfy and devide

Step-by-step explanation:
Part A. The group of points labeled A is the dataset which reveals a decreasing linear relationship. Point B could be considered an outlier because it falls outside the normal pattern of data points. A possible reason for the outlier is that there are other factors effecting students test scores that are not being taken into I account like their environment/homelife, parental involvement in education and students responsibilities , time-management. This may reveal an underlying flaw in the hypothesis as any hours spent in extracurricular activities or other time consuming tasks/chores are not considered either.
part B. In the dataset (group A) there is a decreasing linear relationship meaning that as the number of hours spent playing pc games increases, test scores decrease.
Answer: The volume of the grapefruit is approximately 8 times as great as the volume of the lime.
Step-by-step explanation:
You need to use the formula for calculate the volume of a sphere. This is:
Where "r" is the radius.
<u>Volume of the grapefruit</u>
You know that its diameter is 16 centimeters.
Since the radius is half the diameter, you get that its volume is:
<u> Volume of the lime</u>
According to the information given in the exercise, the diameter of the lime is 8 centimeters.
As it was explained above, the radius is half the diameter. Knowing that, you get that volume of the lime is the shown below:
In order to find approximately how many times as great is the volume of theat grapefruit as the volume of that lime, you need to divide the volumes calculated above. Then:
Answer:
Step-by-step explanation:
First we need to compute the side length as a function of h
So x be the side length of the right isosceles triangle, in Pythagorean formula we have
The cost for the legs is
The cost for the hypotenuse is
So the total cost in term of h is
