Answer:
a. Mean
a. 79 points is an outlier, and the mean is most responsive to outliers.
Step-by-step explanation:
17, 14, 30, 24, 21, and 14
Let's calculate the measure of central tendency of the numbers first.
Mean = 120/6
Mean = 20
For Median
Let's arrange the numbers in ascending order
14,14,17,21,24,30
The median is 17 and 21
Median value =( 17+21)/2
Median = 38/2
Median = 19
Mode = 14.
After 79 was added.
Mean =( 120+79)/7
Mean = 199/7
28.43
For Median
14,14,17,21,24,30,79
Median= 21
Mode = 14
The value that changed the most was the mean value.
Answer:
1 5/6
Step-by-step explanation:
ab = (-2 3/4) * (-4/6)
= ( -11/4) * ( -4/6)
= (11 * 4) / (4 * 6 )
= 11/6
= 1 5/6
Step-by-step explanation:
4/5 + 2/3 = 2215 = 1 715 ≅ 1.4666667. Spelled result in words is twenty-two fifteenths (or one and seven fifteenths).
X = velocity of plane
y = velocity of wind
x - y = 1680/5 = 336 mph .....(1) [ plane flying against the wind]
&
x + y = 1680/4 = 420 mph....(2) [ plane flying with the wind]
Adding (1) and (2) to eliminate y gives
2x = 756
x = 378 mph is the speed of the plane with no wind.
Answer:
a) Table and graph showed
b) The distance will be 231 miles
c) Yes
Step-by-step explanation:
We know the van gets 22 mi/gal, so the distance D in miles traveled by the van can be expressed as
D(g)=22g, being g the number of gallons of gas used
a) The graph of the function D and its corresponding table of values is shown below.
b) If the van used g=10.5 gallons of gas, the distance would be:
D(10.5)=22 x 10.5 = 231 miles
c) The values of g are real in nature because they represent the amount of gas consumed by the van and it can be any real positive number. Being D a linear function of g, it also happens to take positive real values. Then it makes sense to connect the points with lines.
