Answer:
Write a system of equations
Step-by-step explanation:
2x + y = 15
3x - y = 20
5x = 35
x = 7
2(7) + y =15
y = 1
Answer:16 is x
Step-by-step explanation:
this is a equilateral triangle witch means the sides are the same. 3x is more than 2x so they put - 8 to get to 2 x and 8 times 2 is 16 and there you go.
It’s 21 it technically just means your increasing the 15 by 50 percent
Answer:
See attached
Step-by-step explanation:
Given function:
Table and graph are attached
Zeros are included in the graph
<u>Zero's are obtained:</u>
x = 0 ⇒ y = 8
y = 0 ⇒ Solving quadratic equation
- -2x² + 5x + 8 = 0
- x = (-5 ± √(25 + 2*4*8))/-4
- x = 3.608
- x = -1.108
So zeros are (0, 8), (3.608, 0) and (-1.108, 0)
By definition, an absolute frequency is the measure of how frequently an event occurs based on data from an experiment of survey.
This frequency is independent of what the other events in the experiment are and thus is termed absolute frequency.
Thus, for the given question, option B, absolute frequency is the correct option.
