Answer:
7.5 mph
Step-by-step explanation:
Given :
Distance traveled in miles = 10 miles
Time taken = 1 hour 20 minutes
In other to express average speed on terms of miles per hour :
Time in hour = 80 / 60 = 1.333333 hours
Average speed = Distance traveled / time taken
Distance = 10 miles / 1.33333 hours
Distance = 7.5 miles per hour
Answer:
(D) Pie chart
Step-by-step explanation:
The most appropriate method to represent the resulting data is the pie chart. This is because, in this sample, the variables are few and of nominal type.
Of the rest of the options, the only other that could be used is the histogram, since it can represent nominal variables with their corresponding frequency. The rest of the options have other uses not appropriate for this type of sample.
Answer: They have to sell 21 t-shirts to reach their goal.
T-shirt: $5
Goal: $150
$45 has been raised so far (that means they sold 9 T-shirts) 5 x 9 = $45
150/5 = 30 t-shirts (they need to sell 30 t-shirts in the total)
150-45 = They need $105 to archive their goal
105/5 = 21 t-shirts
Answer:
x = -3/8
Step-by-step explanation:
4(3-2x)=15
Distribute
12 -8x = 15
Subtract 12 from each side
12-8x-12 = 15-12
-8x =3
Divide each side by -8
-8x/-8 = 3/-8
x = -3/8
The first plane would be going about 23.83 km/h
