Question:
Obtian the equation that can be used to solve for c
Answer:
Sin50 = 3/c
Step-by-step explanation:
A triangle showing the information given has been attached below for clarity :
Using trigonometry :
AC = 3 = opposite side of angle 50°
AB = c = hypotenus
Using the sine relation of a right angled triangle :
Sin θ = opposite / hypotenus
θ = 50°
Sin 50° = 3 / c
Sin50 = 3/c
Answer: 8mph
Step-by-step explanation:
If Marco bicycles 20 miles in 2.5 hours. divide 20 by 2.5 to get the average rate.
20/2.5 = 8
(Don't forget to add units)
8mph
Answer:
Step-by-step explanation:
A+C=38,000
8A+5C=257,125
Answer:
mean= 5.5
median=5.5
No mode.
range=9
Step-by-step explanation:
Recall that the mean of a data set is the sum of its terms divided by the number of terms.
1+2+3+4+5+6+7+8+9+10=55
55/10=5.5
Recall that the median of a data set is the value at the middle (the median) of the data set. In order to find the median, the data set must be arranged from lowest to highest. Once it is, we cross out one at the end, one at the beginning, one at the end, one at the beginning, and so on until we find the middle value.
Since there are an even number of terms, the median will be between the two middle values. Take the average of the two:
median=5+6 divided by 2=5.5
The mode of a data set is the element that appears most frequently. Since each element in this data set is unique and only appears one time, there is no mode.
Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is
10-1=9
