Answer:
To determine the type of triangle using side lengths, you could use the converse of the Phythagorean theorem, acute triangle inequality theorem, and the obtuse inequality theorem. For example, if the square of the longest side of a triangle is greater than the sum of the squares of the other two sides, than its obtuse. And if the square of the longest side is less than the sum of the squares of the other two sides, then it would be acute. And if the square of the longest side is equal to the sum of the squares of the two other sides, then it would be a right triangle.

Use the box plots comparing the number of males and number of females attending the latest superhero movie each day for a month to answer the questions.
Two box plots shown. The top one is labeled Males. Minimum at 0, Q1 at 3, median at 10, Q3 at 15, maximum at 35. The bottom box plot is labeled Females. Minimum at 0, Q1 at 2, median at 6, Q3 at 9, maximum at 14, and a point at 31.
Part A: Estimate the IQR for the males' data. (2 points)
Part B: Estimate the difference between the median values of each data set. (2 points)
Part C: Describe the distribution of the data and if the mean or median would be a better measure of center for each. (4 points)
Part D: Provide a possible reason for the outlier in the data set. (2 points)
PLEASE HELP ME!!! IVE BEEN AVOIDING THIS FOR SO LONG
(a) The IQR for the males' data is 12, because Q3 is at 15 and Q1 is at 3.
(b) The difference between the median values of each data set is 4 because 10-6 = 4
(c) For the males' data, the median would be a better measure of center, since the data is skewed right. For the females' data, the mean would be a better measure of center, because the data is pretty balanced (except for the outlier).
(d) Maybe a superhero movie had their opening night one day of this month, which would explain the outlier.
Geometry, please answer question ASAP
Answer:
A
Step-by-step explanation:
The inscribed angle IJK is half the measure of its intercepted arc, so
arc IK = 2 × 75° = 150°
The 3 arcs sum to 360° , then
arc IJ = 360° - (150 + 110)° = 360° - 260° = 100° → A
What is an equation of the line that passes through the points (-2,8) and (1, -1)?
Answer:
y = -3x + 2
Step-by-step explanation:
y2 - y1 / x2 - x1
-1 - 8 / 1 - (-2)
-9/3
= -3
y = -3x + b
-1 = -3(1) + b
-1 = -3 + b
2 = b
Find KL
IJ=9
JK=11
KL?
Answer:
KL = 6
Step-by-step explanation:
IL = 26
IJ = 9
JK = 11
KL = ?
To find KL
Let KL be x
IJ + JK + KL = IL
9 + 11 + x = 26
20 + x = 26
transpose to find KL that is x
x = 26 - 20
x = 6
therefore KL = 6
Answer:
KL = 6
Step-by-step explanation:
First step is to create an equation
Given: IL = 26
This means that the sum of the segments that make up IL also equal 26
In other words, IJ + JK + KL = 26 ( note that this is the equation that we will use to solve for the missing segment )
Given: IJ = 9 , JK = 11 and KL = ?
To find the length of the missing segment we simply plug in the known segment lengths into the equation we created and solve for the unknown one.
Equation created: IJ + JK + KL = 26
Variables: IJ = 9 , JK = 11 and KL = ?
Plug in variables into equation
9 + 11 + KL = 26
Now solve for KL
Step 1 Combine like terms ( 9 + 11 = 20 )
20 + KL = 26
Step 2 Subtract 20 from both sides
20 - 20 + KL = 26 - 20
KL = 6
And we are done!

Q. A factory uses 800 watts of electricity in 40 minutes. How many watts does it uses in 3 hours?
Answer:
it uses 3,600 watts of electricity in 3 hours
Electricity used in 40 minutes = 800 watts
So, electricity used in 1 minute
= 800watts/40
= 20 watts
Electricity used in 3 hours
= electricity used in 180 minutes
= electricity used in 1 minute × 180
= 20 watts × 180
= 3600 watts

Why do 6.52 x 10^3 and 652,000 ÷ 10^2 have the same answer?
Answer:
6.52 x 10^3 is just basically 6.52 × 1000, which is 6520. But 652,000 ÷ 10^2 is just 652000 ÷ 100, which is 6520. That's why they have the same answer.

In a study on the placebo effect on 100 students, 64 were found to perform better on tests after taking a fake pill to improve concentration. What is the experimental probability the placebo pill induced better concentration on the student exams?
Answer:
16/25 or 64%
Step-by-step explanation:
In this problem we see that 64 out of the 100 students did better on the exams. So, to find the answer we must find the percentage form of 64 out of 100.
Step one:
what exactly is 64 out of 100? Well, in the math world when we see 'out of' we know that means 'divided by'. So, 64 out of 100 is 64/100.
Step two:
now we have to turn 64/100 into a percentage. We know that 1/100 is 1% so lets multiply 1 by 64. 64*1 = 64. This means that 64/100 = 64%.
I'm not 100% sure what form you need your answer in but if you need it in percentage for the answer is 64%. If you need your answer in a fraction form the answer would be 64/100 or 16/25 if we simplify the answer.

prove that.....cos^2α(cosec^2α-cot^2α)=cos^2α
Step-by-step explanation:
We must prove that
cos²a(csc²a-cot²a) = cos²a
If we look at both sides, we can see that we have cos²a * something = cos²a. Therefore, if we can get that something to equal 1, we have our proof. In this case, that something is csc²a-cot²a. Using this information, we can work from within the parenthesis and go from there.
We can start by expanding the items in the parenthesis. Taking that csc(x) = 1/sin(x) and cot(a) = cos(x)/sin(x), we can say that
cos²a(csc²a-cot²a) = cos²a(1/sin²a - cos²a/sin²a). Because both items in the parenthesis have a denominator of sin²a, we can subtract cos²a from 1 to get
cos²a(1/sin²a - cos²a/sin²a)= cos²a((1-cos²a)/sin²a))
Next, we know that cos²a+sin²a=1, so 1-cos²a = sin²a. Plugging that in, we get
cos²a((1-cos²a)/sin²a)) = cos²a(sin²a/sin²a)
= cos²a(1)
= cos²a

Write the equation of the line that passes through the point (-1, -2) and is parallel to the
graph of y-3x - 2.
XY
Answer:
y = -3x - 5
Step-by-step explanation:
In order to form a parallel line, the two lines must have the same slope. Substitute the values into the point-slope formula to make the equation.
[tex]y-y_1=m(x-x_1)\\y-(-2)=-3(x-(-1))\\y+2=-3(x+1)\\y+2=-3x-3\\y=-3x-5[/tex]
Therefore, the equation is y = -3x - 5.

Step-by-step explanation:
[tex]a^{2} +b^{2} = 150^{2}[/tex]
a=b
[tex]2a^{2} = 150^{2}[/tex]
[tex]a =\sqrt{150^{2}/2 }[/tex]
Answer:
Step-by-step explanation:
We are using a top down view. We have a square building with side length s. The diagonal is 150 ft
Using the Pythagorean theorem
s^2 + s^2 = 150^2
2s^2 = 22500
s^2 =11250
Taking the square root of each side
sqrt(s^2) = sqrt(11250)
s = sqrt(6225*2)
s = 75 sqrt(2)

Margo bought the following lengths of ribbon: 3/4 yd, 1/3 yd, 1/2 yrd. How much ribbon did she buy?
Answer:
she bought 19/12 lengths of ribbon or aka 1 7/12
Step-by-step explanation:
3/4 + 1/3 + 1/2 = 13/12 + 1/2
13/12 +1/2 = 19/12
19/12 simplify is 1 7/12
Margo bought [tex]1\frac{2}{3}[/tex] yards of ribbon.
What is a fraction ?A fraction represents how much part of total quantity is present.Fractions are of two types proper fraction and improper fraction.
According to the question given Margo bought some ribbons of length 3/4 yd, 1/3 yd and 1/2 yd.
To find the total ribbon she bought in yards we have to take the sum of all the fractions.
∴ (3/4) + (1/3) + (1/2) yards.
Now to sum these fractions we have to take LCM of the denominators which is 12.
So, { (3×3) + (1×4) + (1×6) }/12.
= (9 + 4 + 6)/12.
= 19/12 or 1 whole 2/3 yards of ribbon.
