Answer 1

Answer:

68°

Step-by-step explanation:

the interior sum of a triangle is 180 so add and subtract

63 + 49 = 112

180 - 112 = 68

Answer 2

Answer:

w = 68

Step-by-step explanation:

All angles add up to 180 so:

w + 63 + 49 = 180

w + 112 = 180

w = 180 - 112

w = 68

Help asap pls. The mean of a math test took by 50 students is 85% Two students got a 10% on the test. If those outliers were removed, what would the new mean be? Pls don't answer for points. And also DONT ANSWER TO ASK A QUESTION COMMENT IT. it takes away a chance for people who actually know the answer to answer

Answers

Answer:

okay I'm not 100% sure but I have a good idea (it's okay if u remove me it's just an educated guess)

89%

Step-by-step explanation:

if there were 100 students that would mean 1 student represented 1% of the results. so if there were 50 students 1 student would represent 2% of the results. so if two students were removed then that would mean the result would improve by a total of 4% which would get you 89%

more plz help i kinda suck at dependent and independent

Answers

Answer:

I think T is the independant and B is the dependant

Step-by-step explanation:

the amount of time they have is not changed, however the amount of bands they can fit into that time slot is undetermined and relies on the time they have

Answer:

the first option

Step-by-step explanation:

independent is something you can change OR determine

dependent is something that will happen BECAUSE of the independent and you can not change it

in this case- the sentence states that " the amount of time that the venue has been reserved for DETERMINES how many bands will play"

You can change or schedule how long you want to reserve the venue but how many bands that will play depends on the independent variable (t)

Thats why it say determines, because (t) determines or changes (b)

The mean of four numbers is 7. Three of the numbers are 5, 7, and 7. What is the fourth number? Show your work.

Answers

Answer:

4th number = 9

Step-by-step explanation:

let 4th number = X

mean = 7

observations = 5, 7, 7, X

..............................................

mean = sum of observations ÷ numbers of observations

7 = 5+7+7+X ÷ 4

28 = 19 + X

28 - 19 = X

9 = X

The mean of the four numbers is 7. Three of the numbers are 5, 7, and 7. So, the 4th number would be 9.

How to find the mean value of a data set?

The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.

If the data set consists of values

[tex]x_1, x_2, ..., x_n[/tex]

, then we get the mean value as:

[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]

The mean of the four numbers is 7. Three of the numbers are 5, 7, and 7.

let 4th number = X

Mean = 7

observations = 5, 7, 7, X

Mean = sum of observations / numbers of observations

[tex]7 = 5+7+7+X / 4\\28 = 19 + X\\28 - 19 = X\\9 = X[/tex]

6x6x10=360 you have to multiply all sides
To answer this you must split the shape into 2 other shapes at least this how I do it

First do the square 6x6=36
Then do the 2 triangles
3x10=30
(Normally you would divide the answer by 2 since a triangle is half of a square but since there is another triangle this is not needed)
After that add the area of the square to the area of the 2 triangles and your answer is 66

A juice factory offers its juice in both bottles and cans. A class of students on a field trip decides to compare the numbers of cases of bottled juice and canned juice that are packaged each minute. The students count the number of cases that are packaged on each assembly line over several minutes.

What is the unit rate for canned juice, in cases per minute? Explain how you found this unit rate.

Answers

Answer: 50 cases per minute

Step-by-step explanation:

1. Select one of the points on the graph. Let's use (2, 100) in this case.

2. Divide the number of cases (y) by the amount of minutes (x) This means the equation would be 100 ÷ 2.

3. Since 100 cases ÷ 2 minutes = 50 cases per minute, that means that is unit rate, which can be expressed by y = 50x or f(x) = 50x.

50 cases per minute. Hope this helps
