Answer:
134.38
This value represents 134.38
Step-by-step explanation:
Find the mean.
950+620+545+810+775+1120+905+775=6500
6500/8=812.5
Subtract the mean of numbers.
950-812.5=137.5
812.5-620=192.5
812.5-545=267.5
812.5-810=2.5
812.5-775=37.5
1120-812.5=307.5
905-812.5=92.5
812.5-775=37.5
Find the mean.
137.5+192.5+267.5+2.5+37.5+307.5+92.5+37.5=1075
1075/8≈134.38
This means that 134.38 is $134.38
Solution:
The first car can travel 75 miles on 5 gallons of gas.
So per mile gas consumed by car
gallon
The second car can travel 240 miles on 20 gallons of gas.
So per mile gas consumed by car
gallon
It mean Sam should rent the First car.
Sam is renting one of two cars to go on a 300-mile trip.
So total number of gallons of gas required
Total cost of 20 gallons of gas
dollar
Answer:
Step-by-step explanation:
solid line means >=
y >= x+1
dotted line mean >
y > -x-2
combining
the system of inequalities is y >= x+1 and y > -x-2
Answer: The standard deviation was calculated incorrectly.
Step-by-step explanation:
- The standard deviation measures the dispersion of the data values from the mean value.
It cannot be negative , because it is the square root of the variance .
We add all squared deviations from the data points away from the mean and (then divide it by the number of data values) to evaluate variance.
Since , any squared number cannot give a negative result.
⇒ Standard deviation cannot be negative.
⇒The standard deviation was calculated incorrectly.
Rest other things (given in options) can not be interpreted on the basis of given information.
The measure of each base angle is 34 degrees and the measure of the vertex angle is 112 degrees
Find the diagram attached.
The base of the isosceles triangle is "b".
Since the base angles are equal, hence the sum of the interior angle is expressed as:
b + b + 112 = 180
2b + 112 = 180
2b = 180 - 112
2b = 68
b = 68/2
b = 34 degrees
Hence the measure of each base angle is 34 degrees and the measure of the vertex angle is 112 degrees
