find the mean and median for the following.
Answer:
mean = 6
median = 7
Step-by-step explanation:
mean: add all values and divide by the number of values
median: place all values in ascending order and choose the middle value; if there is an even number of values, the median is the mean of the two middle values.
There are 5 values: 7, 8, 8, 4, 3
a) mean
Add all values and divide by the number of values.
mean = (7 + 8 + 8 + 4 + 3)/5 = 30/5 = 6
mean = 6
b) median
Place values in ascending order.
3, 4, 7, 8, 8
The middle value is 7.
median = 7

Question 12
Researchers are investigating how the amount of monthly rainfall measured in centimeters (cm)affects the monthly growth, in cm, of a certain plant. From a sample of data, the researcher
created a least-squares regression line. Computer output is shown in the following table.

T
Intercept 1
0.350
Rainfall
0.025

6.00
Which of the following statements is an interpretation of the value 0.75 shown in the table?
Monthly growth is expected to increase by 0.75 cm when rainfall increases by 1 cm.
B
Rainfall is expected to increase by 0.75 cm when monthly growth increases by 1 cm.
С
For a month with 0 cm of rainfall, the monthly growth is expected to be approximately 0.75 cm.
D
For a plant with Ocm of monthly growth, the month had an expected rainfall of approximately 0.75 cm.
E
Approximately 75% of the variability in monthly growth is due to its linear relationship with rainfall.
Answer:
C
Step-by-step explanation:
We went over it in class.
The value of the y-intercept gives the value of predictor variable, y when the value of the explanatory variable, x is equal to 0.
Therefore, 0.75 is the value of the y-intercept which means that monthly growth will be 0.75 when the amount of Rainfall is 0cm.
The rate of increase per 1 cm increase in monthly Rainfall is the slope value the regression line. The intercept value of y(monthly growth) is 0.75 cm and it is the value of growth when the amount of Rainfall is 0cmThe approximate percentage of variability is given by the coefficient of determination and not the value of the intercept.Therefore, the value 0.75 infers that monthly growth will stand at approximately 0.75 when the value of Rainfall is 0cm.

9. You have a box that is a cube with side length of 10 cm. Will a pencil that
is 17 cm long fit inside the box? Explain your reasoning.
The pencil will fit if its length is smaller than length of the diagonal of the cube
The pencil will fit inside the box
How to determine if the pencil will fit?The dimension of the cube is given as:
L = 10 cm
Calculate the diagonal (D) of the cube using:
D = (3L^2)^(1/2)
So, we have:
D = (3 * 10^2)^(1/2)
Evaluate
D = 17.3
The length of the diagonal is greater than the length of the pencil (17 cm)
Hence, the pencil will fit inside the box

Kim's softball team was playing in the championship game. When there were 4 innings left, the team was losing by a score of 17 to 6 points. In the last 4 innings, her team scored the same number of points per inning, and the other team did not score any more points. Kim's team won with the most points.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
At 4 innings left ;
Kim's team was losing by 17points to 6 points
Given that her team scored the same number of points per inning in the last 4 innings while the other team didn't score any point per inning.
Hence, Kim's team won eventually,
Let point earned per inning = p
Hence, the number of points scored per inning : would be ;
Initial point of Kim's team + (number of innings left * point per inning) > point of opposing team
6 + 4p > 17
4p > 17 - 6
4p > 11
p > 11/4
p > 2.75
Nearest whole number :
Kim's team scored 3 points per inning

Nana has a water purifier that filters \dfrac13 3 1 start fraction, 1, divided by, 3, end of the contaminants each hour. She used it to purify water that had \dfrac12 2 1 start fraction, 1, divided by, 2, end fraction kilogram of contaminants. Write a function that gives the remaining amount of contaminants in kilograms, C(t)C(t)C, left parenthesis, t, right parenthesis, ttt hours after Nana started purifying the water.
Answer:
(1/2) * (2/3)^t
Step-by-step explanation:
Nana has a water purifier that filters 1/3 of the contaminants each hour. She used it to purify water that had 1/2 kilogram of contaminants.
Write a function that gives the remaining amount of contaminants in kilograms, C(t), t hours after Nana started purifying the water.
C(t)=
The water purifier will filter 1/3 of the current contaminants each hour.
1/3 ÷ 1/2
= 1/3 × 2/1
= 2/3
This means, it willreduce the contaminant into 2/3 of it current mass
To derive the equation,
Multiply the contaminant with 2/3 every hour
(1/2) * (2/3)^t
Where t = hours

3. A function f(x) has a slope of -and passes through
the point (-3,7). Explain how the graph of f(x)
could be used to find the y-intercept.
Answer:
Well. this is kinda trivial.
For a function f(x) = y.
The y-intercept is defined as the point where the graph of f(x) intersects the x-axis.
This always happens at x = 0.
So the y-intercept is equal to f(0).
Now, if we have the graph of f(x), you simply can see at what value of y does the graph intersect the x-axis, and that will be the y-intercept.
