Answer: 0.6
Step-by-step explanation:
The stock market dropped 220 points on Monday. It lost another 48 points on Tuesday, and on Wednesday, it gained 96 points. What was the amount of change over those three days.
Request you to finish this please
48 points gained in those 3 days.
Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.
Subtract 220-48.It‘ll be 172.
Add 172 with 96. 172+96=268.
Subtract 268 with how much points the stock market had 3 days ago. 268-220.
Sot eh stock market gained 48 points in 3 days.

Answer:
8.9
Step-by-step explanation:
1. DE:BC=AD:AB
2. AD=AB+BD, but according to the conditions AB=5, then
AD=5+BD.
3. after the substitution DE=16; BC=9; AB=5 and AD=5+BD into the formula:
16:9=(5+BD):5;
[tex]\frac{16}{9} =\frac{BD+5}{5};[/tex]
BD=80/9 - 5≈3.9.
4. if AD=AB+BD, then AD=5+3,9=8,9

A recent report indicated that 22 percent of the households in a certain community speak a
language other than English at home. A reporter will randomly select a household from the
community until the first houehold that speaks a language other than English at home is
selected. Let random variable Q represent the number of attempts needed until the first
household that speaks a language other than English at home is selected. The random variable
Q has a geometric distribution with p = 0.22. Which of the following is closest to the variance
of the random variable?
Answer:
16.1157
Step-by-step explanation:
The random variable Q has a geometric distribution with p = 0.22. The variance of the random variable will be 16.1157.
What is the variance of the random variable?A spread measure for a random variable distribution quantifies how much the values of a random variable deviate from the value that is predicted.
For a discrete random variable, the variance is determined by adding the square of the difference between the value of the random variable and the anticipated value, together with the chance that the value of the random variable will occur, across all of the values of the random variable.
It is given that 22 percent of people in the community speak a language other than English at home.
The required number of tries should be represented by the random variable Q.
The geometric distribution of the random variable Q has a p-value of 0.22.
The variance of a random variable is
V(Q) = (1-p)/p²
V(Q) = (1-0.22)/(0.22)²
V(Q) =0.78/0.484
V(Q) =16.1157
Thus, the random variable Q has a geometric distribution with p = 0.22. The variance of the random variable will be 16.1157.

Answer: Angle 1 = 150 - corresponding angles
Angle 2 = 150 - alternate exterior angles
Step-by-step explanation:
To find the measure of angles ∠1 and ∠2, we are using vertical angle theorem and corresponding angles concept.
From the given figure measure of one of the angle is 150°.
What are angles of parallel lines?Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.
Corresponding angles are angles that occur on the same side of the transversal line and are equal in size. They are either both obtuse or both acute.
Here, ∠1 = 150° (Corresponding angles)
∠1 =∠2 = 150° (Vertically opposite angles are congruent)
To find the measure of angles ∠1 and ∠2, we are using vertical angle theorem and corresponding angles concept.

Revenue from Monorail Service, Las Vegas In 2005 the Las Vegas monorail charged $3 per ride and had an average ridership of about 28,000 per day. In December 2005 the Las Vegas Monorail Company raised the fare to $5 per ride, and average ridership in 2006 plunged to around 19,000 per day.
a. Use the given information to find a linear demand equation.
b. Find the price the company should have charged to maximize revenue from ridership. What is the corresponding daily revenue?
c. The Las Vegas Monorail Company would have needed $44.9 million in revenues from ridership to break even in 2006. Would it have been possible to break even in 2006 by charging a suitable price?
Answer:
A)The required linear demand equation ( q ) = -4500p + 41500
B) $4.61
$95680.55
C) No it would not have been possible by charging a suitable price
Step-by-step explanation:
A) find the linear demand equation
given two points ; ( 3, 28000 ) and ( 5, 19000 )
slope ( m ) = ( y2 - y1 ) / ( x2 - x1 )
= ( 19000 - 28000 ) / ( 5 - 3 ) = -4500
slope intercept is represented as ; y = mx + b
where y( 28000) = -4500(3) + b
hence b = 41500
hence ; y = -4500x + 41500
The required linear demand equation ( q ) = -4500p + 41500 ----- ( 1 )
p = price per ride
B ) Determine the price the company should charge to maximize revenue from ridership and corresponding daily revenue
Total revenue ( R ) = qp
= p ( -4500p + 41500 )
hence R = -4500p^2 + 41500p ------ ( 2 )
To determine the price that should maximize revenue from ridership we will equate R = -4500p^2 + 41500p to a quadratic equation R(p) = ap^2 + bp + c
where a = -4500 , b = 41500 , c = 0
hence p = [tex]-\frac{b}{2a}[/tex] = [tex]- \frac{41500}{2(-4500)}[/tex] = 4.61
$4.61 is the price the company should charge to maximize revenue from ridership
corresponding daily revenue = R = -4500p^2 + 41500 p
where p = $4.61
hence R = -4500(4.61 )^2 + 41500(4.61) = $95680.55
C) No it would not have been possible by charging a suitable price
Write the standard form of the equation of the line parallel to the graph of 9x + 3y = 6 that passes through (0,3).
SHOW YOUR WORK
Answer:
y + 3x = 3
Step-by-step explanation:
Standard Form of the Equation of a Line
The equation of a line in standard form is:
Ax + By = C
Where A, B, and C are constants.
The equation of a line can also be expressed in slope-intercept form, where m is the slope, and b the y-intercept:
y = mx + b
Two lines are parallel if they have the same slope, that is if m1 is the slope of a given line, and m2 is the slope of a parallel line, then m2=m1.
We are given the line:
9x + 3y = 6
Dividing by 3:
3x + y = 2
Solving for y:
y = -3x + 2
The slope of this line is m1=-3, thus the slope of the required line is also m2=-3.
The equation of that required line is:
y = -3x + b
We still don't have the value of b. To find it, we substitute the coordinates of the given point (0,3):
3 = -3(0) + b
Thus, b = 3.
The required equation of the line is:
y = -3x + 3
To write it in standard form, we add 3x:
y + 3x = 3

6/7+9/14 simplify
The problem
Answer:
3/2 or 1.5
Step-by-step explanation:
We need the denominator to be the same so we multiply 6/7 by 2/2 to get 12/14. Now we add 12/14+9/14 which is 21/14. We can simplify 21/14 to 3/2, or 1/5 in decimal form. If you need it in mixed number form, it is 1 1/2
Step-by-step explanation:
[tex] \frac{6}{7} + \frac{9}{14} \\ LCM \: of \: 7 \: and \: 14 \: is \: 98)\\ = \frac{(84 + 63)}{98} \\ = \frac{147}{98} \\ = \frac{3}{2} \\ = 1 \frac{1}{2} [/tex]

Please help! :) (Whoever answers first I'll give Brainlest!)
Answer:
The answer is [10+(9x3]+4 and 5x4+(7x3).
Step-by-step explanation:
I can't really explain, but if you add 10+4, it'll be 14.
If you multiply 9x3, it'll be 27.
So, if you add 27+14, it will be 41.
For the second answer:
If you also multiply 7x3, it'll be 21. If you ALSO multiply 5x4, its 20. So if you add 20+21, it will equal 41.
