Answer:
Q1 A Scatter plot. Q2
Step-by-step explanation:
Q1. We have a data set containing values of car and age group, if we plot value of the car on y-axis and the age on x, it is logical that two different age groups can own a care with same value, so we can have two values on x corresponding to one value on the y-axis, if we can use scatter plot to visually depict this data.
Q2 50 couples with bride age and groom age , here we can take age difference and number of couples that fit in the catogery, a two way table can be used to describe this data(two columns ).
Answer:
Each hour he fly 107.76 miles
Step-by-step explanation:
we know that
Charles Lindbergh flew 3,610 miles in 33.5 hours
To find out the unit rate, divide the total distance by the total time
so

therefore
Each hour he fly 107.76 miles

Answer:
cos(18°)=sin(72°)
Step-by-step explanation:
we know that
In a right triangle
cos(A)=sin(B)
If A and B are complementary angles
so
A+B=90°
In this problem
A=18°
B=90-18=72°
therefore
cos(18°)=sin(72°)
