If A and B are dependent events, which of these conditions must be true? A. P(A and B) = P(A) P(B) B. P(A and B) = P(B) P(A) C. P(B|A) = P(B) D. P(A|B) = P(A) E. P(B|A) P(B).
The true condition about the dependent events, P(B|A) is not equal to P(B).
What is dependent probability?Dependent events in probability mean events whose occurrence of one affect the probability of occurrence of the other.
Two events are said to be dependent if the outcome or occurrence of the first affects the outcome or occurrence of the second so that the probability is changed.
Also, Two events are said to be independent if the outcome or occurrence of the first does not affect the outcome or occurrence of the second so that the probability is not changed.
For independent events: P(A and B) = P(A) x P(B).
Recall that P(B|A) = P(A and B) / P(A) = P(A) x P(B) / P(A) = P(B).
Therefore, for dependent events, P(B|A) is not equal to P(B).

Answer:
-11
Step-by-step explanation:
See the picture for your understanding.
Since a and b are oppoiste angles of 80° and 60° respectively
a = 80°
b = 60°
Since sum of three angles in a triangle is 180°
x + 51 + 60° + 80° = 180°
x = -11
A and C are right angles. p =
degrees.
Answer
Find out the m∠p .
To prove
As in ΔDAB is a right triangle
Apply pythagorean theorem
Hypotenuse ² = Perpendicular ² + Base²
DB² = AB² + AD²
AB = 5 units
AD = 6 units
Put in the above formula
DB² = 5² + 6²
= 25 + 36
= 61
= 7.8 units (approx)
Now in ΔDCB is a right triangle .
By using the trignometric identity .
As DC = 4 units
DB = 7.8 units (approx)
Put all the values in the trignometric identity .
∠p = 59.15 ° (approx)
What is the radius of a circle with the equation x2 y2 – 14x 10y = 250?.
Answer:
Step-by-step explanation:
x² + y² - 14x - 10y = 250
(x² - 14x) + (y² - 10y) = 250
Divide the co efficient of x by 2 ⇒ 14÷2 = 7
Divide the co efficient of y by 2 ⇒ 10÷ 2 = 5
Now, add 7² and 5² to both sides of equation. {addition property of equality}
(x²- 2*7x + 7²) + (y² - 10y + 5²) = 250 + 7² + 5²
(x - 7)² + (y - 5)² = 250 +49 + 25
(x -7)² + (y - 5)² = 324
(x -7)² + (y - 5)² = 18²
Radius = 18
Mr Sosha teaches 4 math classes, with the same number of students in each class. Of those students , 80 are sixth graders and 40 are fifth graders. Write an equation to determine whether there 22, 25, or 30 students in each class. How many are in each class?
Answer:
30
Step-by-step explanation:
80 + 40 = 120
120 represents the total students for all 4 classes. And since there is an even amount in each class...
120 / 4 = 30
So 30 would be your answer.
The Science Club went on a two-day field trip. The first day the members paid $60 for transportation
plus $11 per ticket to the planetarium. The second day they paid $90 for transportation plus $8 per
ticket to the geology museum. Write an expression to represent the total cost for two days for the
n members of the club.
An expression that represents the total cost in dollars for two days for the n members of the club is
given by
Answer:
day 1 total $60+$15=$75
day 2 total $95+$12=$107
total 2 days = $181
Step-by-step explanation:
Answer:
Total cost for two days for the n members of the club = 155 + 27 n
Step-by-step explanation:
Total number of persons = n
The first day the members paid $60 for transportation plus $15 per ticket to the planetarium.
Day 1 cost = 60 + 15 x n = 60 + 15 n
The second day they paid $95 for transportation plus $12 per ticket to the geology museum.
Day 2 cost = 95 + 12 x n = 95 + 12 n
Total cost = Day 1 cost + Day 2 cost
Total cost = 60 + 15 n + 95 + 12 n = 155 + 27 n
Total cost for two days for the n members of the club = 155 + 27 n
QUESTION 1 of 10: The cost of a garment was determined to be $12. 50. You have been instructed to lower the cost to $10 per garment. What
is percentage you were asked to reduce the cost by?
Answer:
20%
Step-by-step explanation:The answer is minus 2.50 so if you plug 12.50 times .2 you get your answer
The percentage reduction is 20% if the cost of a garment was determined to be $12. 50.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
The cost of a garment was determined to be $12. 50. You have been instructed to lower the cost to $10 per garment.
The difference in cost = 12.50 - 10
The difference in cost = $2.50
The percentage reduction = (2.50/12.50)100
The percentage reduce = 20%
Thus, the percentage reduction is 20% if the cost of a garment was determined to be $12. 50.

There are sto students in a school. If the number of boys and girls are in the ratio 4:3, find their numbers.
Answer:
number of boys = 320
number of girls = 240
Step-by-step explanation:
Total students in school = 560
Ratio of boys to girls = 4 : 3
Add the ratios together: 4 + 3 = 7
Divide the total by this number: 560 ÷ 7 = 80
Now multiply the original ratio numbers by 80 to find the numbers of boys and girls:
⇒ number of boys = 4 x 80 = 320
⇒ number of girls = 3 x 80 = 240
Total students are 560.
Let boys be 4x and girls 3x[tex]\\ \rm\hookrightarrow 4x+3x=560[/tex]

tommy went to frosty and bough fruit slushies for $0.75 each and cones for $1 each. He spent a total of $12.75 and bought 15 total items. How many of each item did he buy?
Answer:
9 fruit slushies; 6 cones
Step-by-step explanation:
Let f = number of fruit slushies.
Let c = number of cones.
c + f = 15
c + 0.75f = 12.75
0.25f = 2.25
f = 9
c + f = 15
c = 6
Answer: 9 fruit slushies; 6 cones
Sam Kramer earns an annual salary of $38,900. He is paid semimonthly. His personal exemptions total $4826. The state income tax on taxable wages is 2% of the first $1000, 3% on the next $3000, 3. 5% on the nest $3000, and 4% on the amount over $7000. How much is deducted from Sam’s salary each pay period for state income tax?
Step-by-step explanation:
we pay taxes of the income without the exemptions.
so, the tax-interresting amount is
38,900 - 4826 = $34,074
2% of the first $1000 = $20
$34,074 - 1000 = $33,074
3% of the next $3000 = $90
$33,074 - 3000 = $30,074
3.5% of the next $3000 = $105
$30,074 - 3000 = $27,074
4% of $27,074 = $1,082.96
so, in total he pays state taxes over a year
20+90+105+1082.96 = $1,297.96
now, he gets paid semimonthly, that means twice a month.
his salary but also his deductions (incl. tax deductions) are all split across these 24 paychecks per year.
so, each state income tax deduction is then
$1,297.96 / 24 = $54.08 on every paycheck.

Answer:
80
Step-by-step explanation:
3x8=24
7x8=56
24+56=80
For the 7x8, I'm not including x1/2 also because if we do it once without the x1/2, then it will take it for 2 triangles, and that's what we have here.
So hence, the area of the trapezoid is 80sq.units

v
[tex] \frac{72000}{s} [/tex]
Answer:
72000/s
Step-by-step explanation:
In order to find the number of seats in each section, think of 72000 people as the total number of people that need a seat.
If you want to find how many people can go to each section evenly, you need to divide the number of people by the number of sections.
Now that the same number of people are going to each section, this will give you the number of seats in each.

I will give Brainliest to the first person :)
Answer:
(4k^2+7)(7k+6)
Step-by-step explanation:
1. group the first two terms (28k^3-24k^2). The greatest common factor is 4k^2. If you factor that out you get 4k^2(7k-6)
2.When you group the last two terms (49k-42). you can factor out a 7.
7(7k-6).
3. There is a (7k-6) in both sections so you can combine all the terms.
4k^2(7k-6) 7(7k-6) becomes (4k^2)(7k-6)

Carl is standing the top of 35ft cliff looking down at a rock for notion in the sea. He estimates the angle of depression to the formation is 30' . What is the hozonal distance from Carl to the island?
Answer:
70 ft
Step-by-step explanation:
If you draw a diagram, a right triangle is formed from this scenario. Because Carl is directly 35 ft above the ground, this represents the opposite side length in the triangle model. The distance between Carl and island would represent the hypotenuse.
The trig function that corresponds with opposite and hypotenuse legs is Sine.
The equation is sin(30°) = [tex]\frac{35}{h}[/tex]
sin(30) is 1/2. The value of h that would make this equation true is 70. Therefore he is 70 feet away from the island
