Answer:

Any of the 4 sequences gives another rectangle

Explanation:

Any rotation or traslation you make over a rectangle wont change the fact that you have still a rectangle.

The same will happen if you make a reflection of any on the axis. Therefore any of the 4 sequences given will give you a rectangle.

Here are Barry Bonds's home-run totals, mostly for the San Francisco Giants, during the years 1991 - 2005:25, 34, 46, 37, 33, 42
elixir [45]

Answer:

Refer the attached figure.

Step-by-step explanation:

Given : Here are Barry Bonds's home-run totals, mostly for the San Francisco Giants, during the years 1991 - 2005

The data A={25, 34, 46, 37, 33, 42, 40, 37, 34, 49, 73, 46, 45, 45}  

To find : Modified box plot for this distribution?

Solution :

Arranging the data from lowest to highest,

{25,33,34,34,37,37,40,42,45,45,46,46,49,73}  

Find the median of the data  

As the data is even numbers so the median is

M=\frac{40+42}{2}=\frac{82}{2}=41

Median = 41

For Box plot Graph,

q_1=Q(A,0)

q_1=25

q_2=Q(A,0.25)

q_2=34.75

q_3=Q(A,0.5)

q_3=41

q_4=Q(A,0.75)

q_4=45.75

q_5=Q(A,1)

q_5=73

Plotting the Box plot of the data.

Refer the attached figure below.

The mean GPA of student in a course at UCDevis is 3.2 with a standard deviation of 0.3. What percent of student in a course have
Orlov [11]

Answer:

81.86%

Step-by-step explanation:

We are given that the mean GPA of students in a course at UC Davis is 3.2 with a standard deviation of 0.3.

Assuming that the data follows normal distribution.

Let X = GPA of students in a course at UC Davis

So, X ~ Normal()

The z score probability distribution for normal distribution is given by;

                              Z  =   ~ N(0,1)

where,  = population mean GPA = 3.2

           = standard deviation = 0.3

Now, the probability that the students in the course have a GPA between 2.9 and 3.8 is given by = P(2.9 < X < 3.8)

       P(2.9 < X < 3.8) = P(X < 3.8) - P(X  2.9)

       P(X < 3.8) = P(  <  ) = P(Z < 2) = 0.97725

       P(X  2.9) = P(    ) = P(Z  -1) = 1 - P(Z < 1)

                                                        = 1 - 0.84134 = 0.15866

The above probability is calculated by looking at the value of x = 2 and x = 1 in the z table which has an area of 0.97725 and 0.84134 respectively.

Therefore, P(2.9 < X < 3.8) = 0.97725 - 0.15866 = 0.8186

Hence, 81.86% of students in the course have a GPA between 2.9 and 3.8.

What are the dimensions of the rectangle shown below? Remember to use the axes on the coordinate grid to help you.
miskamm [114]
Keep in mind its been a while since i did this type of work lol.....

did you try to draw it out on a grid paper....what will be helpful is if you got the coordinates and put the points down and then if you connect the dots you get your shape now you will count the unis in which the width and length is timed. so like if you had grid and it gave you coordinates and you did all that now you will count how many units is in the width and how many in the length. 
 but your best answer might be 14 units x 4 units

What is the numerical sum of the degree measures of ∠DEA and ∠AEB?
inessss [21]
The angles are supplementary, therefore totaling them at 180°.

And because I'm bored, I'll solve for x for you!

(x + 25) + (9x + 10) = 180
10x + 35 = 180
Subtract 35 from both sides.
10x = 145
Divide by 10 on both sides.
x = 14.5

N ΔCAB, if the measure of segment AB is 8 units and the measure of segment segment AC is 5 units, which of the following could b
muminat

Answer:

∴Third side = 12 units

Step-by-step explanation:

In ΔCAB, the measure of segment AB is 8 units and the measure of segment AC is 5 units.

The sum of two sides of a triangle always grater than third side.

Therefore,

(5+8)=13 units

third side<13

∴Third side = 12 units
