Solution 1.
Number of times the dice is rolled
= 11 + 22 + 7 + 8 + 13 + 19
= 80
Number of time 4 appeared = 8
Probability
= No. of preferred outcomes/Total number of outcomes
= 8/80
= 1/10
= 0.1
Solution 2.
Number of times the dice is rolled
= 11 + 22 + 7 + 8 + 13 + 19
= 80
Number of time 2 appeared = 22
Probability
= No. of preferred outcomes/Total number of outcomes
= 22/80
= 11/40
= 0.275
2s to expect if dice is rolled 400 times
= 0.275 × 400
= 110
Which angle pairs are supplementary? Check all that apply. ∠1 and ∠2 ∠4 and ∠3 ∠4 and ∠5 ∠7 and ∠5 ∠3 and ∠6.
Answer:
∠4 and ∠3
∠4 and ∠5
∠3 and ∠6.
Step-by-step explanation
Find the diagram attached
First you must note that the sum of two supplementary angles is 180°
Also, since the sum of angle on a straight line is 180°, the angles that are supplementary must lie on the same straight line.
Based on the diagram, the pair of angles that lies on the same straight line are ∠4 and ∠3, ∠4 and ∠5 and ∠3 and ∠6. If that is the case, hence this angles are supplementary.
Answer:
Answer is B.∠4 and ∠3, C.∠4 and ∠5, E.∠3 and ∠6
Step-by-step explanation:

Please help quick for 25 points with explanations. Any silly and absurd answers will be reported.
Answer:
Note that the tangents to the circles at A and B intersect at a point Z on XY by radical center. Then, since∠ZAB=∠ZQA and ∠ZBA=∠ZQB. ∠AZB+∠AQB=∠AZB+∠ZAB+∠ZBA=180°. ∴ZAQB is cyclic.But if O is the center of w, clearly ZAOB is cyclic with diameter ZO, so ∠ZQO is 90° ⇒Q is the mid-point of XY.Then, by Power of a Point, PY· PX = PA · PB = 15 and it is given that PY+PX = 11. Thus,PX=(11±[tex]\sqrt{61}[/tex])/2. So, PQ=[tex]\frac{\sqrt{61} }{2}[/tex], PQ²=[tex]\frac{61}{4}[/tex]. Thus, the answer is 61+4=65.

Target is having a huge winter season sale on all of their televisions. A 42in screen tv that usually retails at $580 is marked down by 20%. If you brought $450 to the store, do you have enough money to buy the tv? Explain your reasoning.
Answer: You do not because the tv costs $464.
Step-by-step explanation:
First find out how much 20% of 580 is:
= 20% * 580
= $116
The television was therefore marked down by $116. The current selling price is:
= 580 - 116
= $464
Since you came with $450, you will not be able to buy the television as you would be short of the $464 required.

Which equation represents the line with a slope of 5/6 that passes through the point (−2,1)?
Answer:
y = 5/6x + 8/3
Step-by-step explanation:
Remember that the slope intercept formula is:
y = mx + b (m is the slope and b is the y-intercept)
We know that slope = 5/6 therefore m = 5/6
So far we have the equation: y =5/6x + b
Now we must find b
To do that, you must plug in the point the line goes through in the x and y of the equation. Point (-2, 1) go through the equation:
y = 5/6x + b
1 = 5/6(-2) + b
Now solve for b
First, you will multiply 5/6 by -2
1 = -5/3 + b
Add 5/3 to both sides
1 + 5/3 = -5/3 + 5/3 + b
8/3 = b
Now that we have b, we can now complete the equation.
y = 5/6x + 8/3
The equation which represents line with slope 5 / 6 and passes through the point ( - 2 , 1 ) is y = 5 / 6 x + 8 / 3
What is a Linear Equation?
A linear equation is an algebraic equation of the form y = m x+ c involving only a constant and a first-order (linear) term, where m is the slope and c is the y-intercept.
Given data ,
Slope of the equation m = 5 / 6
Line passes through the point P ( x , y ) = P ( -2 , 1)
So the linear equation is y = m x + c
Substituting the value of slope m in equation , we get
y = ( 5 / 6 ) x + c
Substituting the values of x and y from the point P ( x , y ) = P ( -2 , 1) , we get
1 = ( 5 / 6 ) × ( - 2 ) + c
1 = ( - 5 / 3 ) + c
c = 1 + ( 5 / 3 )
And c = 8 / 3
Therefore , the equation y = m x + c becomes , y = ( 5 / 6 ) x + 8 / 3
Hence , the equation which represents line with slope 5 / 6 and passes through the point ( - 2 , 1 ) is y = 5 / 6 x + 8 / 3

Find the measure of angle KMJ
Answer:
54 Degrees
Step-by-step explanation:
We know that the interior angles of a triangle add up to 180 degrees.
we also know that angle KLM = 48 degrees
and angle JKM = 78 degrees
since these triangles are on parallel lines we know that their angles must be equal (just inverted)
and thus:
180 - (48+78) = 54
what is the measurement for N?
Answer:
ans: (D) 141°
Step-by-step explanation:
since, straight angle has 180°
180 = 39 + N
N = 180 - 39
N = 141°

Answer:
x = 3.6, y = 0.4
Step-by-step explanation:
make x the subject in equation 1:
x = 4 - y (equation 3)
substitute equation 3 into equation 2:
2(4-y) - 3y = 6
8 - 2y - 3y = 6
8 - 6 = 5y
2 = 5y
y = 2/5
y = 0.4
substitute (y=0.4) into equation 3:
x = 4 - 0.4
x = 3.6

Mike discovered that the pool in his backyard is leaking slowly. The pool holds 17,897 gallons of water, and is leaking at a rate of 5 gallons per day. If Mike does not replace the water that has leaked from the pool, how many gallons of water will remain in the pool after 187 days?
Answer:
Gallons of water remaining = 16,962 gallons
Step-by-step explanation:
Total capacity of the pool = 17,897 gallons
Rate of leakage per day = 5 gallons
Number of days = 187 days
how many gallons of water will remain in the pool after 187 days?
Gallons of water remaining = Total capacity of the pool - (Rate of leakage per day × Number of days
= 17,897 - (5 × 187)
= 17,897 - 935
= 16,962 gallons
Gallons of water remaining = 16,962 gallons

To compare two fractions one has to convert them to a common denominator (number underneath the fraction bar). This can be done by finding the LCM (least common multiple) of the two denominators, and then multiplying the numerator and denominator of each respective fraction such that the fraction's denominators are the same. Now all one has to do is compare the numerators, the numerator with a greater value indicates that the fraction is larger.

Explanation:
If the amount of change due to rounding is the same for both numbers, the original difference and the difference of rounded values will be the same. This will always be the case if the hundredths digits are the same to start with.
Example:
A = 0.56 ⇒ C = 0.6
B = 0.66 ⇒ D = 0.7

B - A = 0.66 -0.56 = 0.10
D - C = 0.7 -0.6 = 0.10 . . . . . same as B - A, ∴ Dominic is incorrect.
