Answer:
Approximately 50% of the vehicle speeds were less than 42 mph
Step-by-step explanation:
The normal distribution is symmetric:
That is, 50% of the measures are below the mean and 50% of the measures are above the mean.
In this problem, we have that:
Mean = 42 mph
So
Approximately 50% of the vehicle speeds were less than 42 mph
Here,
Time: 4 years
Rate: 5%
Simple interest:500$
So, principal:?
We know,
SI=P*T*R/100
500=P*4*5/100
500=20P/100
20P=50000
P=50000/20
P=2500$
So 2500$ is needed to make atleast 500$ interest in 4 years with 5% rate
Answer:
See below.
Step-by-step explanation:
Using the right triangle altitude theorem, the correct proportions are:
AC = 20 cm
CB = 15 cm
Answer:
The last choice, the graph.
Step-by-step explanation:
The 4 relations are:
A.
A set of ordered pairs.
This is not a function because 2 ordered pairs have the same x-coordinate, 1.
B.
Table.
All ordered pairs have 0 as the x-coordinate. Since the same x-coordinate appears more than once, it is not a function.
C.
x = 3y^2 - 7
This is a function of y, and it is a horizontal parabola, so it does not pass the vertical line test. It is not a function.
D.
The graph.
This is a function because it passes the vertical line test.
Answer: The last choice, the graph.
Percent means parts out of 100
18%=18/100=1.8/10=0.18
0.18<0.70
18%<0.7
0.7 is larrger because math
