Answer:

Option C

Step-by-step explanation:

Option C would map (1,3) to (-1,4).

$(x,y)\rightarrow(x-2,y+1)$

$(1,3)\rightarrow(1-2,3+1)\rightarrow(-1,4)$

1 - 2 = -1

3 + 1 = 4

Option C should be the correct answer.

The lengths, in minutes, of the movies currently showing at a movie theater are shown in the data set. Create a histogram

alexdok [17]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the required lengths are not given.

I will use the following data set to answer the question.

$Dataset: 35, 51, 39, 42, 68, 62, 32, 59$

First, is to determine the range of the dataset

$Range = Highest - Least$

$Range = 68 - 32$

$Range = 36$

Next, we will make use of 4 classes. So, we divide range by 10 to get the number of class. 10 represents the interval

$Class= Range/10$

$Class = 36/10$

$Class = 3.6$

$Class \approx 4$

So, we use 4 classes

Plot the frequency distribution table as follows:

$\begin{array}{ccc}{Intervals} & {Observations} & {Frequency} & {31-40} & {32,35,39} & {3} & {41-50} & {42} & {1} & {51-60} & {51,59} & {2} & {61-70} & {62,68} & {2}\ \end{array}$

James had a peach that was 98mm in diameter. One day he watered it with a magical solution, and it grew to 188,869 mm in diamete

Archy [21]

We know that 98mm is the 100% of the diameter of the plant before James watered with the magical solution; after he watered, the diameter of the plant grew to 188.869mm. Let $x$ be the grew in the percentage of the diameter.
Now we can establish a ratio and solve for $x$ :
$\frac{98}{100} = \frac{188.869}{x}$
$x= \frac{(188.869)(100)}{98}$
$x=192.7$ %
Now that we know the diameter of the plant grew 192.7%, we just need to divide that quantity by 100% to find how many times the diameter grew:
$\frac{192.7}{100} =1.927$

We can conclude that the diameter of the peach become approximately 1.9 times larger after James watered it.

The amounts below show the change (measured in feet) in water level over four months. What is the average monthly change in wate

Harlamova29_29 [7]

Answer:

The average change in water level is: -3/4

Step-by-step explanation:

The average is calculated by adding up all the values and then dividing the sum by total number of values.

Given values are:

3/4, -9/4, -11/4, 5/4

The sum of values will be:

$=\frac{3}{4}+(-\frac{9}{4})+(-\frac{11}{4})+\frac{5}{4}\\=\frac{3}{4}-\frac{9}{4}-\frac{11}{4}+\frac{5}{4}\\=\frac{3-9-11+5}{4}\\=\frac{-12}{4}\\=-3$

Total number of values is 4

So,

$Average = \frac{Sum}{Values}\\= \frac{-3}{4}$

Hence,

The average change in water level is: -3/4
