316,480 if I get it right can I get brainlist
Answer:
B. 120
Step-by-step explanation:
<u>so his average speed is 20 mph in heavy traffic, and 50 mph in light traffic</u>
in 1 hour of heavy traffic, he would have gone 20 miles because if his average speed is 20 mph (miles per hour) in heavy traffic, then in 1 hour he would have gone 20 miles
20(1) = 20
in 2 hours of light traffic, he would have gone 100 miles because if his average speed is 50 mph (miles per hour) in light traffic, then in 2 he would have gone 100 miles
50(2) = 100
in total, if you add the 20 and 100, you find out how far abdul traveled:
20 + 100 = 120
so in 1 hour of heavy traffic and 2 hours in light traffic, abdul would have traveled 120 miles
Answer:
Slope m = 1/-2
Step-by-step explanation:
Given the formula for slope of a line to be
m = y - y_1 / x - x_1
Only if a point is given
But in this case, we are given two points
( 1 ,4 ) and ( -1 , 5)
x_1 = 1
y_1 = 4
x_2 = -1
y_2 = 5
Inserting the values given into the formula
m = y_2 - y_1 / x_2 - x_1
m = 5 - 4 / -1 - 1
= 5 - 4= 1
= -1 - 1 = -2
m = 1/ -2
Therefore, the slope of the line is 1 /-2
Answer:
(a)Mean=9
(b)Median=9.5
(c)Mode=12
(d)Standard Deviation=2.53
Step-by-step explanation:
The sample of the number of vehicles that proceeded through the intersection after the light changed for 6 days during a 1 month period is given below:
6 12 7 12 8 9
(a)Mean
(b)Median
First, arrange in ascending order
6,7,8,9,12,12
Since we have two terms in the middle, we take the average.
(c)Mode
The mode is the number with the highest frequency. The mode number of cars is 12.
(d)Standard Deviation
