In the given figure, find the measure of angle BOC, angle COD and angle DOE ?
Answer:
Step-by-step explanation:
[tex]2x - 10^o + 2x + 30^o + x + 10^o + 50^o = 180^o \\\ 5x + 80^o = 180^o \\\ 5x = 180^o - 80^o \\\ 5x = 100^o \\\ x = \frac{100^o}{5} \\\\ x = 20°[/tex]
I hope I've helped you.
Explanation:-
From the given figure :
∠AOB = 50°
∠BOC = x+10°
∠COD = 2x+30°
∠DOE = 2x-10°
We know that
The sum of the angles lie on the same line = 180°
⇛ ∠AOB + ∠BOC + ∠COD + ∠DOE = 180°
⇛ 50°+x+10°+2x+30°+2x-10° = 180°
⇛ 5x+80° = 180°
⇛ 5x = 180°-80°
⇛ 5x = 100°
⇛ x = 100°/5
⇛ x = 20°
∴ x = 20°
Now,
The measure of ∠BOC = x+10°
= 20°+10°
= 30°
The measure of ∠COD = 2x+30°
= 2(20°)+30°
= 40°+30°
= 70°
The measure of ∠DOE = 2x-10°
=2(20°)-10°
= 40°-10°
= 30°
Answer:-
The measure of ∠BOC = 30°
The measure of ∠COD = 70°
The measure of ∠DOE = 30°
Remember:-The sum of the angles lie on the same line is 180°

jill and her brother jack both walked up a hill. they started at the same time, but jill arrived at the top ten minutes before jack. while resting at the top, jack calculated that if he had walked 50% faster and jill had walked 50% slower, then they would have arrived at the top at the same time. how long did jack actually take to walk up to the top of the hill?
It took Jack 15 minutes to walk up to the top of the hill.
Let v = Jill's speed and v' = Jack's speed. Let t = time it takes Jill to walk up to the top of the hill, since Jill arrives 10 minutes earlier, Jack's time, t' = t + 10.
Since the distance covered by both Jack and Jill is the same, we have that
vt = v't'
vt = v'(t + 10)
Since Jack calculated that if he walked 50 % slower and Jill 50 % faster, they would arrived at the top at the same time, Jack's new speed is V = v' + 0.5v'. (since there is a 50 % increase in speed).
Also, Jill's new speed is V' = v - 0.5v (since there is a 50 % decrease in speed)
Since they both arrive at the top at the same time, T, and the distance covered is equal, we have that VT = V'T
(v' + 0.5v')T = (v - 0.5v)T
1.5v' = 0.5v
v'/v = 1.5/0.5
v'/v = 3
From (1)
vt = v'(t + 10)
(v'/v)t = t + 10
3t = t + 10
3t - t = 10
2t = 10
t = 5 minutes
Since Jack's time t' = t + 10, substituting t = 5 into the equation, we have
t' = t + 10
= 5 + 10
= 15 minutes
So, it took Jack 15 minutes to walk up to the top of the hill.

Answer: a = 0.98
Explanation: For this case we have the following table:
x | P(x)
0| 0.1296
1| 0.3456
2| 0.3456
3 | 0.1536
4| 0.0256
We can find the expected value as:
E(X)= 0*0.1296 + 1*0.3456+ 2*0.3456+ 3*0.1536+ 4*0.0256= 1.6
Now we can find the second moment like this:
E(X^2)= 0^2*0.1296 + 1^2*0.3456+ 2^2*0.3456+ 3^2*0.1536+ 4^2*0.0256= 3.52
And the variance is given by:
Var(X)= E(X^2)- [E(X)]^2 = 3.52 -(1.6^2)=0.96
Then the standard deviation is:
Sd(X)= sqrt(0.96)=0.98

Answer:
Reflected along x axis
Translated 7 units to the right
Step-by-step explanation:
If a point (x, y) is reflected along the x axis, its x coordinate remains the same and the y coordinate is opposite (negated). The new point is at (x, -y)
If a point (x, y) is translated h units to the right, the new coordinate is (x+h, y).The transformation are as follows:
It is reflected along the x axis so that the new coordinates would be at A1 at (- 4, -4), B1 at (- 2, -2), C1 at (- 2, 1), D1 at (- 4, -1)
It is translated 7 units to the right, The new coordinates are A' at (3, -4), B' at (5, -2), C' at (5, 1), D' at (3, -1)

Step-by-step explanation:
Column 3, labeled 20 Years, would be the column you want for a 20-year loan.
Row 2, labeled 5.5%, would be the row you want for a 5.5% loan.
The value in the table at row 2 of column 3 appears to be 6.88. The is the amount of the payment per $1000 of loan value. A $160,000 loan will have a monthly payment that is 160 times $6.88 = $1100.80.
The 20-year loan will be paid back with 20×12 = 240 monthly payments. The total amount of those payments will be ...

The figure is obviously rotated 180°. If the rotation is first, the image would be in the 4th quadrant, where it would stay after translation downward.
If the translation is downward first, it would be in the 3rd quadrant, moving to the first quadrant after rotation by 180°. This is the apparent sequence of transformations:

the mean is 100. One individual score is at the 20th percentile and has a raw score of 85. What is the standard deviation
Answer:
Look at it this way. About two-thirds of the populace are thought to possess IQs between 85 and 115, which is to say, more or less average. That leaves about one sixth of the populace significantly below average and one sixth significantly above average.
Why such a large range for average — there’s a 30-point gap between 85 and 115? That’s because IQ tests measure only certain kinds of intelligence, and people who might be weak in some areas might be strong in other areas. Consider the difference between being book-smart and being street-smart. A person who is book-smart would be expected to score well on an IQ test but might not fare so well in a dangerous neighborhood after dark. A person who is street-smart would know better than to visit that neighborhood after dark but might not score so well on an IQ test.
Step-by-step explanation:
Answer:
Step-by-step explanation:
To calculate the value of the standard deviation in this equation, we must use Z-scores, therefore we are assuming that the distribution is regular.
At the twentieth percentile of a regular distribution, the z-score is -2.88. Using this information we can reverse-engineer the z-score calculation equation, [tex]z=\frac{n - x'}{s_{x} }[/tex]. x' being the mean of 100, n being the value of 85, z being the z score of -2.88 and s base x being the standard deviation.
[tex]-2.88=\frac{85-100}{s_{x}}[/tex].
The standard deviation is equivalent to 5.2083
A survey of 70 people found that 50 like coffee, 25 like tea, and 13 like both. How many people like coffee or tea, or both?
62 people like coffee or tea, or both
A survey of 70 people found that 50 like coffee, 25 like tea, and 13 like both.
The amount of people that like only coffee = 50 - 13 = 37
The amount of people that like only tea = 25 - 13 = 12
The amount of people that like neither = 70 - (37 + 12 + 13) = 8
The amount of people who like coffee or tea, or both = 37 + 12 + 13 = 62

Answer:
13 like both
12 like tea
37 like coffee
62 people like coffee, tea or both
8 don't like neither of them
Step-by-step explanation:
let us remember that 25 people like tea but 13 of them like both. And 50 people like coffee but 13 like both.
so:
25-13=12
12 equals to the number of people that only like tea.
50-13=37
37 equals to the number of people that only like coffee.
If you add the 13 (that like both) + 12 (that like tea) + 37 (that like coffee) that equals to 62 people that like coffee or tea, or both.
13+12+37=62
62 equals to the number of people that like coffee or tea, or both
So that means that 8 people don't like either coffee or tea.

Answer:7 on both sides all together 14
Step-by-step explanation:32 is length and width combined so 18 all together for width which leaves 14 cm for width so both sides are 7
Answer:
width ≥ 7 cm
Step-by-step explanation:
The perimeter formula is ...
P = 2(L +W)
We have P ≥ 32 and L = 9. We want to find W. (Dimensions are cm.)
2(9 +W) ≥ 32 . . . . substitute for P and L
2W ≥ 14 . . . . . . . subtract 18 and simplify
W ≥ 7 . . . . . . . . . divide by 2
Possible widths are at least 7 cm.
