Answer:
m<1=117
m<2=99
Step-by-step explanation:
Answer:
Angle 1 is 117 degrees.
Angle 2 is 59 degrees.
Step-by-step explanation:
Let angle 1 be x, and angle 2 be y.
By the exterior angle theorem, x + 21 = 138, so x = 138 - 21 = 117.
Again, by the exterior angle theorem, 79 + y = x = 138, so y = 138 - 79 = 59.
The drive from savannah to Milwaukee takes approximately 15.5 hours how long is the drive in minutes

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $30,000 and $50,000. Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. Given the information in the Microsoft Excel Online file below, construct a spreadsheet to determine how large a sample should be taken for each desired margin of error.
Answer:
A. 384.16
B. 2,401
C. 9,604
D. No
Step-by-step explanation:
Calculation to determine how large a sample should be taken for each desired margin of error
First step is to find σ which represent Population Standard deviation
σ=($50,000-$30,000)/4
σ=$20,000/4
σ = 5,000
Now let calculate how large a sample should be taken for each desired margin of error
Using this formula
n = (Za/2*σ/E)^2
Where,
Za/2=1-0.95/2
Za/2=0.05/2
Za/2=0.025
Z-score 0.025=1.96
Za/2=1.96
σ =5,000
E represent Desired margin of error
Let plug in the formula
a. $500
n = (1.96* 5,000/$500)^2
n=(9,800/$500)^2
n=(19.6)^2
n = 384.16
b. $200
n = (1.96*5,000/200)^2
n=(9,800/$200)^2
n=(49)^2
n = 2,401
c. $100
n = (1.96*5,000/$100)^2
n=(9,800/$100)^2
n=(98)^2
n = 9,604
Therefore how large a sample should be taken for each desired margin of error will be :
A. $500= 384.16
B. $200= 2,401
C. $100= 9,604
d.NO, Based on the information calculation i would NOT recommend trying to obtain the $100 margin of error reason been that it is highly costly compare to $500 margin of error and $200 margin of error.

Answer:
square, parallelogram, rectangle, rhombus
Step-by-step explanation:
Considering the answer choices:
Square
Regular pentagon
Parallelogram
Rectangle
Rhombus
It can't be a pentagon because it only has four sides.
Properties of the shapes:
Rectangle - quadrilateral with two sets of congruent opposite sides and four right angles.
Rhombus - quadrilateral with four congruent sides.
Square - quadrilaterals with all properties of rectangles and rhombi.
Parallelogram - rectangles, rhombi, and squares are parallelograms.
This shape satisfies the properties of a square, meaning it is also a rectangle, rhombus, and parallelogram.
For the following compound interest problem, how much interest would you earn if you put $600 in the bank at 5.5% for 2.25 year.
Answer:
$74.25
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year,
then, solving our equation
I = 600 × 0.055 × 2.25 = 74.25
I = $ 74.25
The simple interest accumulated
on a principal of $ 600.00
at a rate of 5.5% per year
for 2.25 years is $ 74.25.

(20 Points) What is the solution to the equation [tex]\frac{1}{8}[/tex]n = 4?
Answer:
The answer to this question is n=2
Step-by-step explanation:
What is the equation of 35?
35 - X = 5
Simplifying
35 + -1X = 5
Solving
35 + -1X = 5
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-35' to each side of the equation.
35 + -35 + -1X = 5 + -35
Combine like terms: 35 + -35 = 0
0 + -1X = 5 + -35
-1X = 5 + -35
Combine like terms: 5 + -35 = -30
-1X = -30
Divide each side by '-1'.
X = 30
Simplifying
X = 30

Your digital camera has a 512 megabyte memory card. You take pictures at two resolutions, a low resolution requiring 4 megabytes of memory per photo and a high resolution requiring 8 megabytes of memory per photo. Write an equation to model the amount of each kind of photo you can take.
One possible answer is 8H + 4L = 512
=======================================================
Explanation:
H = number of high resolution photosL = number of low resolution photosH and L are placeholders for positive whole numbers, or 0 could replace either variable.
1 high resolution photo takes up 8 mb of space, so H of them take up 8H megabytes of space.
1 low resolution photo takes up 4 mb of space, so L of them take up 4L megabytes.
Overall, the two types of photos take up 8H+4L megabytes, which is equal to 512 since that's the max capacity. That leads to the equation 8H+4L = 512
----------------------------------
Extra info:
There are other ways to express the equation 8H+4L = 512. We could divide each part by 4 to get 2H+L = 128, but I think this equation loses its descriptive quality in a way. We no longer can see that each high resolution photo takes up 8 megabytes (instead we might mistakenly think only 2 megabytes are used per high resolution photo). A similar mistake may happen with the low resolution photos also.
The equation 2H+L = 128 can be rearranged into L = -2H+128 when solving for L.

Determine if the expressions 100 divided by (25 divided by 5) and (100 divided by 25) divided by 5 are equivalent. If so, tell what property is applied. If not explain why.
Answer:
They aren't equivalent because when using P.E.M.D.A.S you solve what is in the parenthesis first. After you solve what is in the parenthesis the two expressions are completely different.
Step-by-step explanation:
100/(5)=20 (4)/5= .8
The requried results of the two expressions are different (20 and 0.8), the expressions are not equivalent.
Expression 1:
100 ÷ (25 ÷ 5)
Evaluate the expression inside the parentheses.
25 ÷ 5 = 5
Replace the expression inside the parentheses with its result:
100 ÷ 5
Perform the division:
100 ÷ 5 = 20
So, the result of Expression 1 is 20.
Expression 2:
(100 ÷ 25) ÷ 5
Evaluate the expression inside the first set of parentheses.
100 ÷ 25 = 4
Replace the expression inside the first set of parentheses with its result:
4 ÷ 5
Perform the division:
4 ÷ 5 = 0.8
So, the result of Expression 2 is 0.8.
Since the results of the two expressions are different (20 and 0.8), the expressions are not equivalent.
The reason why they are not equivalent is due to the order of operations. In Expression 1, we first divide 25 by 5 and then divide 100 by the result, while in Expression 2, we first divide 100 by 25 and then divide the result by 5.

This one is hard because it will depend on what numbers you pick for each measurement.
-----------------------------------------------------------------------------
if a = 1, b = 2, c = 3, d = 4, and e = 5
find the volume for all the shapes
The post
V = lwh = (1)(1)(2) = 2
The bottom of the mailbox
V = lwh = (3)(4)(5) = 60
The top of the mailbox
V = πr²h = (3)(5)π = 15π = 48.2
Then add them all together:
2 + 60 + 48.2 = 110.2 is the total Volume

Which of the following could represent the question: How many 4/9s are in 6/5 as a multiplication equation?
x*4/9=6/5
x*6/5=4/9
6/5*4/9=x
4/9*6/5=x
Answer:
Select the third answer listed which states: 6/5 * 9/4
Step-by-step explanation:
To find how many of a quantity x are in another quantity y, we normally divide in the following fashion:
y divided by x = y ÷ x = y / x
Then we do the same here: 6/5 divided by 4/9 = 6/5 ÷ 4/9 = 6/5 * 9/4

So we are playing with variables here, lets look at 1.
5x + 9 = 29 if x = 4
This means that if x equals 4, would it make the equation true? Let's find out :
Substitute :
5(4) + 9 = 29
20 + 9 = 29
This is true, let's do the same for 2. :
7x - 8 = 13 if x = 3
7(3) - 8 = 13
21 - 8 = 13
This is also true.
