Answer:
the measure of x is 38
Step-by-step explanation:
180-134=46 the value of one side of a line is 180 degrees so to find the vaule of the inside angle we have to subtract 180 by the outside angle's
180-84=96
46+96=142 we then add the value's of both inside angles
180-142= 38
then we subtract that number by 180 because the total of all three angles of any triangle is always 180
Answer:
x = 38°
Step-by-step explanation:
Maths problem always go back to a number of foundational rules;
Once you recognise the ones that are relevant, you can then apply them to find the value or solution you want to find;
First thing is to look at the question and information provided in order to identify the relevant rules;
This question is asking for an angle and we can see a triangle (not a right-angle triangle) and line beneath it;
What rules should we think of with this in mind?
The following;
Angles in any triangle always add to 180°Angles on a straight line add to 180°Using these rules, we can find x;
Firstly, according to rule 2, we can find angle OLM:
134 + OLM = 180
OLM = 180 - 134
OLM = 46
Secondly, also according to rule 2, we can find angle OML:
84 + OML = 180
OML = 180 - 84
OML = 96
Lastly, according to rule 1, we can find angle x:
OLM + OML + x = 180
46 + 96 + x = 180
x = 180 - 96 - 46
x = 38

Answer:
y=-1/7x
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-1)/(7-(-7))
m=-2/(7+7)
m=-2/14
simplify
m=-1/7
--------------------
y-y1=m(x-x1)
y-1=-1/7(x-(-7))
y-1=-1/7(x+7)
y=-1/7x-7/7+1
y=-1/7x-1+1

Answer: < less than
Step-by-step explanation:
1. Find LCM of 20 and 13.
20: 20,40,60,80,100,120,140,160,180,200,220,240,260,280
13: 13, 26, 39, 52, 65, 78, 91, 104, 107, 110 ...... 234, 247, 260
The LCM is 260.
2. 20*13 = 260 13*20=260
therefore we need to multiply the numerator by those 13 and 20.
8*13 = 104 7*20 = 140

Step-by-step explanation:
2x + 3y = 18
x + y = 7, so x = 7 - y
Substitute in for x
2(7 - y) + 3y = 18
14 - 2y + 3y = 18
14 + y = 18
y = 4
Now put 4 in for y to solve for x
2x + 3(4) = 18
2x + 12 = 18
2x = 6
x = 3

8x =8
Divide both sides of the equation by 8 to have:
8x/8 = 8/8
x = 1

The number of potholes in any given 1 mile stretch of freeway pavement in Pennsylvania has a bell-shaped distribution. This distribution has a mean of 47 and a standard deviation of 7. Using the empirical rule, what is the approximate percentage of 1-mile long roadways with potholes numbering between 40 and 68?
Answers
This value is approximate.
==========================================================
Explanation:
Let's compute the z score for x = 40
z = (x-mu)/sigma
z = (40-47)/7
z = -1
We're exactly one standard deviation below the mean.
Repeat these steps for x = 68
z = (x-mu)/sigma
z = (68-47)/7
z = 3
This score is exactly three standard deviations above the mean.
Now refer to the Empirical Rule chart below. We'll add up the percentages that are between z = -1 and z = 3. This consists of the two pink regions (each 34%), the right blue region (13.5%) and the right green region (2.35%). These percentages are approximate.
34+34+13.5+2.35 = 83.85
Roughly 83.85% of the one-mile roadways have between 40 and 68 potholes.
