Required data table is attached below :

Answer:

D. The fewest students prefer black Model A1 calculators.

Step-by-step explanation:

From the data Given :

Larger proportion of students prefer White calculators(0.65) to black calculators (0.35)

Also, Fewer proportion of students like black model C3 (0.20) than white model A1 (0.40)

Also, the proportion of students who like model C3 calculators(0.30) are fewer than those who prefer the model A1 (0.45)

Therefore, the true inference which can be derived from the data is, the least preferred calculator is the Black model A1 calculator with a proportion of 0.05

7(5x - 13) = 14

vfiekz [6]

Answer:

Part A, one solution

Part B, x=3

Step-by-step explanation:

divide both sides of the equation by 7 (5x-13=2)

move the constant to the right hand side and change its sign (5x=2+13)

add numbers (5x=15)

divide both sides of the equation by 5 (x=3)

hope this helps, have a good day

Please help, I’m very confused

Answer:

1st picture: (0,4)

The lines intersect at point (0,4).

2nd picture: Graph D

2x ≥ y - 1

2x - 5y ≤ 10

Set these inequalities up in standard form.

y ≤ 2x + 1

-5y ≤ 10 - 2x → y ≥ -2 + 2/5x → y ≥ 2/5x - 2

When you divide by a negative number, you switch the inequality sign.

Now you have:

y ≤ 2x + 1

y ≥ 2/5x - 2

Looking at the graphs, you first want to find the lines that intersect the y-axis at (0, 1) and (0, -2).

In this case, it is all of them.

Next, you would look at the shaded regions.

The first inequality says the values are less than or equal to. So you look for a shaded region below a line. The second inequality says the values are greater than or equal to. So you look for a shaded region above a line.

That would mean Graph B or D.

Then you look at the specific lines. You can see that the lower line is y ≥ 2/5x - 2. You need a shaded region above this line. You can see the above line is y ≤ 2x + 1. You need a shaded region below this line. That is Graph D.
