Part A.
Before you can write any sort of expression, you need to define variables. "grapes g" is not a definition, so the exercise seems meaningless as written. It seems the intent is to ...
let g, b, p represent the numbers of pounds of grapes, bananas, and pears, respectively.
Then, the total cost of some weight of fruit is
2.19g + 0.59b + 1.49p
Part B.
For g=3, b=3, p=2, the expression evaluates to
2.19*3 +0.59*3 +1.49*2 = 11.32
The total cost of 3 pounds of grapes, 3 pounds of bananas, and 2 pounds of pears is ...
$11.32
The answer is a.
Symmetric distribution have the same mean and median.
Answer:
A) Case A we dont rally have a nrmal distribution in case C
(See step by step explanation)
Step-by-step explanation:
Normal Distribution curve is a function of mean and standard deviation with these values we can plot the curve. The mean usually denoted by μ will show the most frecuent value of the population ( or sample ) and the standard deviation is a measure of the spread of the values around the mean. If we assume that for hitting the axis we should understand that the two given values are the end of the curve, then we can evaluate how spread is each of the curve then:
case A 115 - 75 = 40
case B 72 - 48 = 24
case C We do not touch x -axis in this case so curve is open we can find distribution values (theoretically) from -∞ to +∞ we dont really have a normal distribution in this case.
case D 38 - 28 = 10
Then if we dismiss case C the biggest standard deviation will be case A.
Note: we do not need to calculate standard deviation we just need to look how width it is
300 miles/5 hours=60 miles per hour
420 miles/7 hours=60 miles per hour
therefore they both have an equivalent proportion of 60 miles per hour
Given :
Time they traveled in a day , 
.
Average speed , 
.
To Find :
How far did they hike altogether in 4 days .
Solution :
We know , distance covered is given by :
So , distance covered in 4 days is :
Therefore , distance they hike in 4 days is 38.5 miles .
Hence , this is the required solution .
