Answer:
6. x = 28 degrees
7. z = 1.6 cm
Step-by-step explanation:
6.
Notice that you can use the property that tells us that the addition of all internal angles of a triangle must give 180 degrees, then you write the following equation:
50 + 69 + (2 x +5) = 180
combine like terms:
119 + 2 x + 5 = 180
124 + 2 x = 180
subtract 124 from both sides:
2 x = 56
divide by 2 both sides:
x = 56 / 2
x = 28 degrees
Problem 7.
If the two triangles are congruent, then the side MN must equal side RS.
Since MN measure 1,8 cm, then RS must also measure 1.8 cm
and we can write the equation:
1.8 = 3 z - 3
adding 3 to both sides:
1.8 + 3 = 3 z
4.8 = 3 z
dividing both sides by 3:
z = 4.8 / 3
z = 1.6 cm

How do you find what p is?
Answers
Answer:
p > -3
Step-by-step explanation:
This is an alternating p-series. It is absolutely convergent if│an│converges. 1 / nᵖ⁺³ converges if the exponent is greater than 1.
p + 3 > 1
p > -2
The series is conditionally convergent if │an│diverges. 1 / nᵖ⁺³ diverges if the exponent is greater than 0 and less than or equal to 1.
0 < p + 3 ≤ 1
-3 < p ≤ -2
Combining these two, we get p > -3.

Step-by-step explanation:
B. Yes, we are 99% confident that the population mean is within the interval.
C. Yes, 225 is below the interval minimum, so it is reasonable to conclude the average cholesterol level is greater than 225 mg/dl.
D. No. Increasing the sample size would decrease the margin of error, so the ends of the interval would move closer to the sample mean of 251.9. So the interval minimum would still be higher than 225.

Which line is perpendicular to y=2x-7
Answers
Answer:
y=-1/2x−5/2
Step-by-step explanation:
The equation of a line perpendicular to given line is y=-x/2.
The given equation of a line y=2x-7 and passes through the point (0, 0).
What is slope of an equation?The slope formula is used to calculate the inclination or steepness of a line. It finds application in determining the slope of any line by finding the ratio of the change in the y-axis to the change in the x-axis.
The standard form of equation of a line is y=mx+c, where m=slope and c=y-intercept.
So, slope of a given equation is y=2x-7
m=2
Now, slope of a line perpendicular to given line is -1/m = -1/2
Put m= -1/2 and (0, 0) in y=mx+c and simplify.
That is, 0=0+c
c=0
Then, the equation of a line is y=-x/2
Therefore, the equation of a line perpendicular to given line is y=-x/2.

A normal population has mean =μ7 and standard deviation =σ5. (a) What proportion of the population is less than 18?
Answers
Answer:
P(x< 18) = 0.986
Step-by-step explanation:
Step 1: find the z-score using the formula, z = (x - µ)/σ
Where,
x = randomly chosen values = 18
µ = mean = 7
σ = standard deviation = 5
Proportion of the population that is less than 18 = P(x < 18)
Plug in the values into z = (x - µ)/σ, to get z-score.
z = (18 - 7)/5
z = 11/5 = 2.2
Step 2: Find P(x< 18) = P (z<2.2) using z-table.
The probability that corresponds with z-score calculated is 0.986.
Therefore,
P(x< 18) = 0.986

Find mo 8 5 m n o
Mo=
Answers
Answer:
MO is 13 units
Step-by-step explanation:
If point lies on a segment, then this point divides the segment into two parts, the sum of their lengths equals the length of the segment
∵ Point N ∈ segment MO
→ That means point N divide segments MO to two parts MN and NO
∴ Point N divides segment MO into two parts MN and NO
→ That mans the length of segment MO equals to the sum of
lengths of MN and NO
∴ MO = MN + NO
∵ MN = 8 units
∵ NO = 5 units
∴ MO = 8 + 5
∴ MO = 13 units

Just one more question I need this in a step by step please
Answers
Answer:
2x+20+3x+40=90
5x+60=90
5x=30
x = 6
2x+20 = 2(6)+20
12+20
=32
3x+40 = 3(6)+40
18+40
=58
Answer:
Here we can first find the value of x simply by using the concept of corresponding angles.
As we know that angle with measurement 2x+20Degree and the right angle below are corresponding as we can consider the line (underlined in red) as a transversal intersecting lines underlined in green. {PLEASE SEE THE ATTACHMENT TO SEE THE HIGHLIGHTED LINES}
So, we get 2x+20 degree = 90 degree.
= 2x+20=90
= 2x=90-20
= 2x=70
= x= 70/2
= x=35 degree.
Now as we know the value of x we can find the other unknown angle by substituting it in the equation for the other angle.
Therefore, 3x+40degree= 3*35+40
105+40
= 145 degrees.

does the surface in contact with ground affect the going motion of the car ?why?
Answers
Answer:
Yes, it does. The ground is bumpy and it creates friction acting against the car's motion.

Step-by-step explanation:
This is a fun one! Think about a ball rolling on a smooth surface, now on a bumpy sandpapery one. Which one do you think is faster? The smooth surface! This is because of this friction of the sandpaper which slows down the ball. On the other hand, the smooth one has very little friction. The same applies to cars.
