Answer:
Step-by-step explanation:
To calculate the speed of each one we proceed as follows:
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)
=10/3×5/3
=5 5/9 mi/hr
Anna was the fastest

Answer:
There are many points that are solutions to the equation, but one of which would be (1, 2)
Step-by-step explanation:
In order to tell if they are a solution, we use the values in the inequality and see if it results in a true statement.
y < -1/2x + 2
1 < -1/2(1) + 2
1 < -1/2 + 2
1 < 3/2 (This is a true statement)
Since it is a true statement, we know it is a solution.
4 rock, 2 reggae, 2 country...total of 8
P(1st song is reggae) = 2/8 which reduces to 1/4
P(2nd song is reggae) = 1/7
P(both events happening) : 1/4 * 1/7 = 1/28
<u>Answer:</u>
The expected value of construction company is $30500.
<u>Solution:</u>
Given, A construction company is planning to bid on a building contract.
The bid costs $1,500 and has an 80% chance of being accepted.
If accepted, the company will receive $40,000 dollars.
We have to find the expected value.
We know that,
Expected value = probability 
amount gained by bidding – bid amount
Expected value = 80% x 40000 – 1500
Expected value = 0.8 x 40000 – 1500
Expected value = 32000 – 1500
Expected value = 30500
Hence, the expected value is $30500.
