No, You only reverse the inequality symbol when you divide by a negative number.

State whether the relationship between x and y in y = 0.5x is proportional or non-proportional. Then graph the function.

Mars2501 [29]

Step-by-step explanation:

A relationahip is proportional if both variables can be both 0.

y = 0.5x

(0) = 0.5(0)

Since the equality is true, it is proportional.

To graph the function, plot (0, 0) and (10, 5) on the graph and draw a line through the points.

You must reverse the inequality sign when solving this inequality: x + 7 < 4

SSSSS [86.1K]

I'm not 100% sure what you want me to do with this but i hope this helps:

x < -3

or if you want me to flip the sign then the solution becomes

Mrs. Daly's reading classes were surveyed about their reading preferences. The data is summarized in the table below.

andriy [413]

Answer:

Required probability is 0.19

Step-by-step explanation:

The two-way table for the given data is,

Fiction Non-Fiction Total

9th grade 35 8 43

10th grade 52 12 64

Total 87 20 107

It is required to find the probability of the students who prefer to read non-fiction novels, given that they are in 9th grade.

That is, to find the conditional probability $P(Non-fiction| 9th\ grade)$ .

Now, $P(A|B)=\dfrac{P(A\bigcap B)}{P(B)}$

So, we get,

$P(Non-fiction| 9th\ grade)=\dfrac{(Non-fiction\bigcap 9th\ grade)}{P(9th\ grade)}\\\\P(Non-fiction| 9th\ grade)=\dfrac{8}{43}\\\\P(Non-fiction| 9th\ grade)=0.19$

<h3>Thus, the required probability is 0.19.</h3>
