Shureka Washburn has scores of 80, 76, 85, and 85 on her algebra tests

Mathematics
1 answer:
Aliun [14]2 years ago
8 0

She must have a score greater than 69 in her final tests

Let the required score be "x"

<h3>What is Mean?</h3>

The mean of the data is the ratio of the sum to the total sample

Mean = 80+76+85+85+x/5

80+76+85+85+2x/5 > 79

326+x/5 > 79

326 + x > 395

x > 395 - 326

x > 69

This shows that she must have a score greater than 69 in her final tests

First line joins ordered pairs negative 4, 3 and 2, negative 3. Second line joins negative 4, negative 3 and 2, 3. Part A shaded
elena55 [62]

The part that represents the solution to the inequality will be Part B shaded below first line and above second line.

<h3>How to depict the inequality?</h3>

From the information given, the equation of the first line will be:

y - 3 = (-3 - 3/2 + 4)(x + 4)

y - 3 = -1(x + 4)

y + x = -4 + 3

x + y = -1

The equation of the second line will be:

y + 3 = -1(x + 4)

y = x + 4 - 3

y = x + 1

This is plotted on the graph attached.

From the systems of equations, the statement that is correct about the two systems of equations is that They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 3 times the second equation of System A.
