Which inequality has an arrow pointing to the left when the solution set is graphed on a number line?

kupik [55]

Answer:

$x \le 5$

Step-by-step explanation:

Given

Options (a) to (d)

Required

Which represents an arrow pointing left

When an arrow points left on an inequality graph, the inequality is either of the following:

$x < a$ or $x \le a$

From the given options (a) to (d), only $x \le 5$ fits the above description.

Other options illustrate an arrow pointing to the right

To further explain this;

Looking at (b), we have:

$4 \le x$

This is rewritten as:

$x \ge 4$ --- the same form as (c) and (d)

A campus has 55% male students. Suppose 30% of the male students pick basketball as their favorite sports compared to 20% for fe

krok68 [10]

This is question of probability finding using bayes theorem
It is used to calculate probability of two competing statements
now p(m) = .55
p(~m)= .45
now for basketball for male
p(b|m)=.30
and for female
p(b|~m)=.20
so by bayes theorem
p(m|b)=p(b|m)*p(m)/(p(b|m)*p(m)+p(b|~m)*p(~m))
so answer is E
(.55)(.30) / (.55)(.30) + (.45)(.20)
