1 answer:
Answer (numbers needed in boxes, going from top to bottom):
1
-1
-3
3
Step-by-step explanation:
f(x) is another way of saying y. So, the table is asking, "when substituting these x values for the x's in the function, what does y equal?" So, to answer the question, substitute each x value into the equation and solve.
1) Start with the x value of 1. Substitute 1 for x in y = 2x - 1 and solve:
So, when x equals 1, y equals 1. Therefore, the first box on the top must be filled out with the number 1.
2) Do the same with the rest of the x values. Here are the steps to solve each one, going in order from the top towards the bottom:
x = 0
x = -1
x = 2

Complete Question
The histogram from this question is shown on the first uploaded image
Answer:
The first quartile is
The median is
The third quartile is
The mean is
Step-by-step explanation:
From the question we are told that
The total number of girls is n = 74
Generally the median is mathematically represented as
So
=>
=>
From the histogram fall under 2 fruits per day
Generally the first quartile is mathematically represented as
=>
=>
From the histogram girl fall under 1 fruit per day
Generally the third quartile is mathematically represented as
=>
=>
From the histogram fall under 4 fruits per day
Generally from the histogram table the frequency [number of subjects (girls) ] and the servings of fruit per day can be represented as
Total
x(servings per day ) 0 1 2 3 4 5 6 7 8
f (number of subjects ) 15 11 15 11 8 5 3 3 3
xf 0 11 30 33 32 25 18 21 24
Generally the mean is mathematically represented as
