For what value of x is line / parallel to line m in this figure?
Answers
Answer:
132
Step-by-step explanation:
The angle with a measure of 48 degrees and the angle labeled "x" are supplementary angles. Supplementary angles add up to equal 180
This means that we can find the value of the missing angle by subtracting the measure of the known angle from 180
So x = 180 - 48
180 - 48 = 132
Hence, x = 132
Brenda bought three time more black fabric than red fabric. She bought 72 inches of red fabric. If fabric costs 7.25 per yard, how much did Brenda spend on fabric
Answers
Answer:
$58 dollars
Step-by-step explanation:
Step 1: Find price of Red Fabric. So Brenda bougt 72 inches. So we convert that to amount of yards.(36 inches=1 yard). So the equation is 72/36=2 yards. Then do 7.25x2= $14.50 for red fabric.
Step 2: Find price of Black Fabric. So Brenda bought 3 times more the red favric. So she 216(72x3 is how I got the number). Now divide 216 by 36. That equals 6. So now do 7.25x6= $43.50
Step 3: Add the prices. So now add the price of the red and black fabric to find the answer. So $43.50 + $14.50= $58
Hence, the answer is $58 dollars.

What is Pythagoras theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
The triangle is a right-angled triangle.
The length of the perpendicular = 17 unit.
Two angles of the triangle are 45° and 45°.
That means, base = 17 unit.
And the triangle is an isosceles triangle.
By the Pythagoras' theorem,
a = √(289 + 289)
a = √578
a = 17√2 unit.
Therefore, the value of a is 17√2 unit.

A) x + 2 y = 1
C) x - 2y = 10
B) x-1= 2
D) x – 2y=
Answers
Answer:
B)
Step-by-step explanation:
y-intercept = -2
slope = 1
in slope-intercept form the line would be: y = x - 2
if we subtract 'x' from each side we get:
-x + y = -2
we don't want to leave 'x' as negative so we can multiply each term by -1 to get:
x - y = 2

Step-by-step explanation:
The mode is the number that is repeated the most there can be more than one mode.
Answer:
All in ft
Mean: 28,235
Median: 28,208
Range: 1,245
Step-by-step explanation:
Mean is the sum of the elements divided by the number of elements.
(29035+28250+28208+27890+27790)/5 = 28235
Median is the element in the exact middle of the set (if there is an even number of elements, take the average of the two elements in the middle).
After rearranging the numbers, we can see 28208 is in the exact middle.
27790 27890 28208 28250 29035
Range is the difference between the smallest and largest number in the set.
29035-27790=1245

For a 95% confidence interval what would the sample size need to be as it's most conservative to have a 2% margin of error
Answers
Answer:
The size of the sample 'n' = 2401
Step-by-step explanation:
Step:1
Given that the margin of error = 2 % = 0.02
The margin of error is determined by
[tex]M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]
we know that the proportion
[tex]\sqrt{p(1-p)} < \frac{1}{2}[/tex]
Step:2
The margin of error is determined by
[tex]0.02 = \frac{1.96( \frac{1}{2} ) }{\sqrt{n} }[/tex]
[tex]\sqrt{n} = \frac{1.96}{2 X 0.02}[/tex]
√n = 49
Squaring on both sides, we get
n = 49 × 49
n = 2401
Final answer:-
The size of the sample 'n' = 2401

James and Katie play a board game online which uses two dice to move around the board. Katie doesn’t have two dice, so uses a 12-sided spinner instead. The rules say that each player moves along the board the number of spaces shown on the two dice together. For example, throwing a 3 and a 6 means the player can move 9 spaces. An extra go is awarded each time the player rolls a double-six – James and Katie agree that Katie earns her extra ‘roll’ if she spins a ‘12’.After playing several games, James claims that Katie must be cheating because she gets many more extra ‘rolls’ than him on every game.
• Try to decide whether James is right. Must Katie be cheating, or is there some other explanation for her luck?
• Use probability to explain why this problem has arisen
• Try to devise a fairer way to play the game.
Answers
Answer:
Katie is not cheating. From the question, it sounds like Katie's spinner is 1-12. James has two dice so he has two sets of each number 1-6. This means that Katie can roll two numbers greater than six but James can only roll up to six. Using probability, I think there is a 50% chance that Katie's number will be bigger than James every time she spins. A fairer way would be for them both to play with the same dice or spinner.
