Answer:
Ian
Step-by-step explanation:
this is because you divide the total wage by how many hours each person works for, ian earns 13 dollars an hour, Cody earns 11 dollars an hour, and Cindy ears 12 dollars and 50 cents per hour.
For this case, what we must do is calculate the mean of the given data.
For this, we must do the following:
Add the given numbers and divide by the number of numbers.
We have then:
From here, we clear the value of x.
We have then:
Answer:
Tasha would have to score 90 on the sixth test to have a mean of 85
Answer:
the area of a trapezoid is equal to half the product of the height and the sum of the two bases. Area = ½ x (Sum of parallel sides) x (perpendicular distance between the parallel sides).
Answer:
B
Step-by-step explanation:
5x - 1 = x =4
<h3>Answer: Choice D</h3>
4x - 3y = 15
====================================================
Explanation:
The two points (-1,-1) and (2,3) are marked on the line
Let's find the slope of the line through those two points.
The slope is 4/3 meaning we go up 4 and to the right 3.
-------------
Parallel lines have equal slopes, but different y intercepts. We'll need to see which of the four answer choices have a slope of 4/3.
Solve the equation in choice A for y. The goal is to get it into y = mx+b form so we can determine the slope m.
Equation A has a slope of -3/4 and not 4/3 like we want.
Therefore, this answer choice is crossed off the list.
Follow similar steps for choices B through D. I'll show the slopes of each so you can check your work.
- slope of equation B is 3/4
- slope of equation C is -4/3
- slope of equation D is 4/3
We have a match with equation D. Therefore, the equation 4x-3y = 15 is parallel to the given line shown in the graph.
You can use graphing tools like Desmos or GeoGebra to confirm the answer.
