A superintendent of a school district wants to understand the link between attendance and grade point average, or GPA. The GPA is out of 4.0 points, with 4.0 being the highest possible. The percent attendance and GPA of 10randomly sampled students from the superintendent's district were collected. This sample data is reproduced in the table below. Calculate the correlation coefficient r using a TI-83, TI-83 plus, or TI-84 graphing calculator (round your answer to two decimal places).
"GPA" 3.5 2.38 1.16 3.83 3.28 3.69 3.46 3.87 3.69 3.75
Attendance 91% 74% 80% 97% 59% 78% 90% 98% 94% 87%
r=_______.
Answer:
0.4136
Step-by-step explanation:
Given the data:
"GPA":
3.5
2.38
1.16
3.83
3.28
3.69
3.46
3.87
3.69
3.75
Attendance
0.91
0.74
0.80
0.97
0.59
0.78
0.90
0.98
0.94
0.87
The value of R (correlation Coefficient) obtained for the two variables GPA and ATTENDANCE is 0.4136. This shows that a fairly weak relationship between the GPA obtained and the attendance of students. Hence, even though a positive relationship exist between the two variables, that is, an increase in one variable yields a corresponding increase in the other and vice versa. The correlation Coefficient value for both values is just fairly strong.

amy ate 27.5 cookies in 5.5 minutes. How many cookies did she eat per minute?
Answer:
5 cookies per minute.
Step-by-step explanation:
To do this, we divide 27.5 by 5.5 to get the unit rate, in other words, the amount of cookies eaten per minute. This gets us 5. That means Amy ate 5 cookies per minute.
Answer:
Amy ate 5 cookies per minute
Step-by-step explanation:
Do get the unit rate - the number of cookies per minute - you can divide 27.5/5.5. You then get 5. This means that Amy ate 5 cookies per minute.

A rectangular box has length 20cm, width 6cm and height 4cm. find how many cubes of size 2cm that will fit into the box.
Answer:
[tex]\boxed{\pink{\sf The \ number \ of \ cubes \ that \ can \ be \ fitted \ is 60 .}}[/tex]
Step-by-step explanation:
Given dimensions of the box = 20cm × 6cm × 4cm .
Dimension of the cube = 2cm × 2cm × 2cm .
Therefore the number of cubes that can be fitted into the box will be equal to the Volume of box divided by the Volume of the cube. So ,
[tex]\boxed{\red{\bf \implies No. \ of \ cubes \ = \dfrac{Volume \ of \ box}{Volume \ of \ cube }}}[/tex]
[tex]\bf \implies n_{cubes} = \dfrac{20cm \times 6cm \times 4cm .}{2cm \times 2cm \times 2cm } \\\\\bf\implies n_{cubes} = 10 \ times 3cm \times 2cm \\\\\implies \boxed{\bf n_{cubes}= 60 }[/tex]
Hence the number of cubes that can be fitted in the box is 60 .

Step-by-step explanation:

The inequality which is graphed on the coordinate plane is y > -x + 2, the correct option is B.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
An inequality is a mathematical statement that compares two values or expressions using a relational operator, such as less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥), or not equal to (≠). Inequalities are used to describe relationships between quantities or to express constraints or conditions.
We are given that;
The graph of inequality
Now,
the graph shows a dashed line with a slope of -1 and a y-intercept of 2, which is the equation y = -x + 2. The dashed line means that the points on the line are not included in the solution set of the inequality. The shaded region above the line means that the points in that region satisfy the inequality.
Therefore, by the inequality the answer will be y > -x + 2.

To find,
Draw the graph.
Solution,
We have,
y-5>2x-10
First we simplify the above inequality.
Taking variables to LHS and constant to RHS.
y-2x>5-10
y-2x>-5
The points are (0,-5) and (3,1).
The attached figure shows the graph for the above equation. So, the correct graph is in option (2).

The cost of a ticket to a Circus & Fan Fair show is $69 for adults and $26 for children. On a
certain day, 5 times as many children attend the show than adults, and the total revenue is
$94,908. About how many adults bought tickets?
Let the number of adults equal x, and the number of children equal 5x.
26(5x) + 69x = 94908
194x = 94908
x = approx. 489
About 489 adults bought tickets.
A total of 489 adults take tickets to the circus & Fan Fair show.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of tickets that adults bought is a and the number of tickets that children bought is c.
Then,
26(5a) + 69c = 94908
194a = 94908
a = 489.21 but we need to take the whole number and practical number so it will be 489.
Hence "A total of 489 adults take tickets to the circus & Fan Fair show".

Answer:
{12, 4, -6}
Step-by-step explanation:
f(x)=4-2x
x = -4
f(-4) = 4 - 2(-4) = 12
x = 0
f(0) = 4 - 2(0) = 4
x = 5
f(5) = 4 - 2(5) = -6

Answer:
Rate of interest r = 2.83 % (Approx.)
Step-by-step explanation:
Given:
Amount invested p = $2,600
Amount get A = $4,300

In distributions in which many scores differ greatly from the distribution’s mean, the bigger the:
A) statistical significance.
B) correlation.
C) reliability.
D) standard deviation.
Answer:
In distributions in which many scores differ greatly from the distribution’s mean, the bigger the:
D) standard deviation.
Step-by-step explanation:
The more spread out or variable a data distribution is, the greater its standard deviation. A standard deviation is the square root of the variance. A mean is an average of all set of available data. It is obtained by dividing the value of data by the number of the data set. The standard deviation is the statistics that basically measure the distance from the mean, and is calculated as the square root of variance determined by each data point relative to the mean.

His restaurant serves about 500 customers a day. He timed 5 orders, and the order times he collected, given in minutes, are shown below. Can the approximate order fulfillment time for all of the restaurant's customers be calculated from the given data? If so, calculate it. Non-integer answers should be rounded to the nearest tenth. If no assumption can be made, type "0" in the box. The approximate order fulfillment time for all of the restaurant's customers is minutes.
