A triangle has sides with lengths of 10 millimeters, 17 millimeters, and 18 millimeters. Is it a right triangle?
Answer:
no, it is not
if it were a right triangle, 10² + 17² = 18²
but this is not the case
Step-by-step explanation:
we would use Pythagoras theorem to determine if it is a right angle
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
10² + 17² =
100 + 289 = 389
square root of 389 is 19.72 and not 18. thus, it is not a right triangle
In order for the data in the table to represent a linear function with a rate of change of +5, what must be the value of a?
a = 3
a = 8
a = 18
a = 33
Answer: C: A=18
Step-by-step explanation: If your are adding 5 every time the x value goes up by one, then you would add 5 to13, henceforth getting 18.
The value of a that completes the table is 18
Rate of change of a functionThe rate of change of a function is expressed in term of the slope.
In order to determine the value of a, we will use the expression below;
Slope = a - 13/4-3 = 23-13/5-3
a-13 = 10/2
a - 13 = 5
Add 13 to both sides
a =5 + 13
a = 18
Hence the value of a that completes the table is 18

A student evaluated -4+x for x = -9 1/2and got an answer of 5 1/2? What might th student have done wrong.
Answer:
Step-by-step explanation:
Expression evaluated by the student is,
(-4 + x)
For x = [tex]-9\frac{1}{2}[/tex]
Value of the expression will be,
(-4 + x) = [tex]-4+(-9\frac{1}{2})[/tex]
= [tex]-4-9-\frac{1}{2}[/tex]
= [tex]-13-\frac{1}{2}[/tex]
= [tex]-13\frac{1}{2}[/tex]
While student evaluated the value of the expression as [tex]-5\frac{1}{2}[/tex].
Mistake done by the student may be in the first step [tex][-4+(-9\frac{1}{2})][/tex].
He might have subtracted [tex](-9\frac{1}{2})[/tex] from (-4).

A company surveyed its employees regarding the number of miles
commuted each day. The data set below shows the results
9, 15, 26, 32, 65, 5, 10, 19, 26, 32, 8, 15, 25
30, 40, 7, 12, 21, 27, 35, 60, 29, 23, 14,8
Using a box plot, determine the outlier value of the data set above.
A. 65
OB. 23
C. 60
D. The data set does not contain an outlier.
E. 5
Answer: According to Study Island the answer is 65
Step-by-step explanation:
In order to determine the outlier value, create a box plot.
To create a box plot, order the data.
5, 7, 8, 8, 9, 10, 12, 14, 15, 15, 19, 21, 23, 25, 26, 26, 27, 29, 30, 32, 32, 35, 40, 60, 65
Find the median, the first quartile (Q1), the third quartile (Q3), and the interquartile range (IQR).
Median = 23
Q1 =
10 + 12
2
= 11
Q3 =
30 + 32
2
= 31
IQR = Q3 - Q1 = 31 - 11 = 20
Find the upper and lower fences for the given data.
Lower Fence = Q1 - 1.5 × IQR
= 11 - 1.5 × 20
= -19
Upper Fence = Q3 + 1.5 × IQR
= 31 + 1.5 × 20
= 61
What is the median. I have 3 more questions that have to deal with the median.
Answer:
47.5Step-by-step explanation:
Median - The middle number in a list of numbers starting from least to greatest.
Knowing this, we can start.
The first step is to rewrite all the numbers from least to greatest
15, 19, 28, 32, 43, 52, 66, 72, 72, 81
Now cross off a number from the least and greatest until there is 1 or 2 numbers left
19, 28, 32, 43, 52, 66, 72, 72
28, 32, 43, 52, 66, 72
32, 43, 52, 66
43, 52
If you are left we 1 number, that is your answer. If you are left with 2 numbers, there is an extra step
In the case that you have 2 numbers, you need to add them together, and divide by 2
43 + 52 = 95
95 ÷ 2 = 47.5
Thus 47.5 is our answer
In physics class, Carrie learns that a force, F, is equal to the mass of an object, m, times its acceleration, a. She writes the equation F=ma.
Using this formula, what is the acceleration of an object with F=7.92 newtons and m=3.6 kilograms? Express your answer to the nearest tenth.
Note: The unit for Force (the Newton) is measured in .
Answer:
2.2
Step-by-step explanation:
if force equals mass times acceleration then you divide 7.92(the force) by 3.6(the mass) to find out what would be multiplied by 3.6 to get 7.92.
Sorry if I'm wrong.
The acceleration of an object with F=7.92 newtons and m=3.6 kilograms is 2.2 m / s²
What is force:Force is a pull or push upon an object that causes motion .
Mathematically, force is express as follows:
F = ma
where
m = mass
a = acceleration
Force is measured in Newton.
Let's find the acceleration of an object with F =7.92 newtons and m = 3.6 kilograms.
7.92 = 3.6a
divide both sides by 3.6
a = 7.92 / 3.6
a = 2.2 m / s²

A total of 40 parents volunteered to bring a cake for the Holiday fair.Of the 40 volunteers that brought cake,10 of them brought two cakes. Out of all the cakes at the holiday Fair , 30% were chocolate. How many cakes were chocolate?
Answer:
15!
Step-by-step explanation:
so 40 people volentered to bring cakes, but 10 brought 2. So (30*1)+(10*2)=50 cakes. So, 30 percent of 50 cakes would be 15. To double check, times 50 by 100 and then 30 percent would become 30 (making super sure the actual answer is 15)

In the first half of the basketball season, Jean made 15 free throws out of the 25 free throws she attempted, for a free-throw shooting percentage of 60%. How many consecutive free-throw shots would Jean have to make to raise her free-throw shooting percentage to 80%?
Answer:
She has to make 25 consecutive free throws
Step-by-step explanation:
Let the number of consecutive throws be x
So, that would mean the number of free throws would total 25 + x
while the number of free throws made would be 15 + x
So for us to have an 80% raise ;
That would mean;
(15 + x)/(25 + x) * 100 = 80
100(15 + x) = 80(25 + x)
1500 + 100x = 2000 + 80x
2000-1500 = 100x-80x
20x = 500
x = 500/20
x = 25
Answer:
She has to make 25 consecutive free throws
Step-by-step explanation:
Let the number of consecutive throws be x
So, that would mean the number of free throws would total 25 + x
while the number of free throws made would be 15 + x
So for us to have an 80% raise ;
That would mean;
(15 + x)/(25 + x) * 100 = 80
100(15 + x) = 80(25 + x)
1500 + 100x = 2000 + 80x
2000-1500 = 100x-80x
20x = 500
x = 500/20
x = 25

Mean = 69Median = 69Mode = {68, 70}===============================================
Explanations:
To get the mean, you add up all of the values and then you divide by N, where N is the number of values in the list. In this case, you'll divide by N = 8.
Adding up all the values gets you 70+68+70+72+68+66+65+73 = 552. Dividing that over 8 then leads to the arithmetic mean of 552/8 = 69
-------
To find the median, you'll first sort the values from smallest to largest. You should have this set {65, 66, 68, 68, 70, 70, 72, 73} after sorting. Next, cross off the smallest and largest values to end up with this smaller set {66, 68, 68, 70, 70, 72}. We do this so we can locate the middle-most item.
Repeat the process of crossing off the smallest and largest items to get {68, 68, 70, 70}. Do so one more time and we get {68,70}.
The midpoint of those two values is (68+70)/2 = 138/2 = 69. The median is 69. The mean and median may not always be the same value.
--------
The mode is the most frequent value. In this case, we have 68 and 70 show up exactly twice for each unique value. This is the most compared to the other unique values that only show up exactly once.
It is possible to have more than one mode, as long those values are more frequent than the rest. We denote the mode as a set, so the mode is {68, 70}
