The cost of one pair of shoes is $8.
The cost of one shirt is $12.
<h3>What are the linear equation that represent the question?</h3>
2a + b = 32 equation 1
2a + 3b = 48 equation 2
Where:
- a = cost of 1 shirt
- b = cost of one pair of shoes
<h3>What is the cost of one pair of shoes?</h3>
Subtract equation 1 from equation 2
2b = 16
b = 16/2
b = $8
<h3>What is the cost of one shirt?</h3>
Substitute for b in equation 1
2a + 8 = 32
2a = 32 - 8
2a = 24
a = 24 / 2
a = $12

Step-by-step explanation:
put it in decimal form. -4/3 is -1.34 so -1.34 = g/.5.
divide -1.34 by .5 and you get g= -2.68 or cose to -8/3.
Using the expected value of a discrete distribution, it is found that:
a) His expected value is of -$2.5.
b) The fair price of a ticket is of $0.5.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the distribution for the net value of the ticket is:
Item a:
The expected value is given by:
His expected value is of -$2.5.
Item b:
With an unknown ticket price, the distribution is:
The game is fair if E(X) = 0, hence:
0.5 - x = 0
x = 0.
The fair price of a ticket is of $0.5.

Answer:
5/3
Step-by-step explanation:
if you find the common denominator for both fractions, 5/3 comes out to 32/24 and 10/8 comes out to 30/24
Answer:
angle 3 is 140°
Step-by-step explanation:
angle 2 and angle 3 are equal
angle 4 and 1 are also equal
angle 3 =
180-40= 140
angle 3 is 140
