I need this math problem to be solved ASAP!!! Solve for X.
1 answer:
Answer:
A: x ≤ −4
Step-by-step explanation:
Hi there!
We're given the two inequalities -8x + 3 ≥ 27 and −13x + 5 ≥ 57
we need to find the set of solutions that make the two inequalities true (the intersection)
First, let's solve the two inequalities, starting with -8x + 3 ≥ 27
-8x + 3 ≥ 27
subtract 3 from both sides
-8x≥24
divide both sides by -8 and remember to FLIP the inequality sign, as we're dividing with a negative
x ≤ -3
now for the other inequality:
−13x + 5 ≥ 57
subtract 5 from both sides
-13x ≥ 52
divide both sides by -13 and remember to FLIP the sign
x ≤ -4
please see below for the graph to find the intersection, as well as the final answer
Hope this helps! :)

The lottery's anticipated worth is $80.
Given that,
The probability of receiving $125 is 0.25; the likelihood of receiving $100 is 0.3; and the likelihood of receiving $50 is 0.45.
A) EV=125*.2+100*.3+50*.5=$80
The lottery's anticipated worth is $80.
The expected value is obtained by multiplying each result by its likelihood.
The expected value of the lottery is then calculated by adding up all of these.
This is what we have: ;;
125(0.2) + 100(0.3) + 50(0.5) (0.5)
= 25 + 30 + 25 = $80
B) This is the formula for variance is shown in figure :
So, we can calculate the variance as follows:
.2*(125-80)^2+.3*(100-80)^2+.5*(50-80)^2=975
C) A risk-neutral person would pay $80 or less to play the lottery.

Answer:
If the lines that forms < X are perpendicular, it can be assumed that it is a right angle.
Step-by-step explanation:
An indirect proof of an angle is an assumption about the value of the angle that can be made by mere inspection and some considerations.
< X = right angle =
A right angle is one that is equal to . As an indirect proof, if the lines that forms the angle are perpendicular; then it can be assumed to be a right angle. Because perpendicular lines are at right angle to one another.
