Answer:
D. 0.80
Step-by-step explanation:
P(A or B) = P(A) + P(B)
P(A or B) = 0.60 + 0.20
P(A or B) = 0.80
The probability of P(A or B ) is 0.80.
The correct option is D.
Since A and B are mutually exclusive events, they cannot occur simultaneously.
Thus, the probability of A or B occurring is equal to the sum of their individual probabilities:
P(A or B) = P(A) + P(B)
Therefore, we need to subtract the probability of the intersection of A and B:
P(A and B) = 0 (since A and B are mutually exclusive)
Thus, we have:
P(A or B) = P(A) + P(B) - P(A and B)
Substitute all the given values to the equation,
we get,
= 0.60 + 0.20 - 0
= 0.80
Therefore, the probability of A or B occurring is 0.80 or 80%.

Kendall bought 6 notbooks and 3 pens for a total of $27. The cost of one notebook is $1.50 more than the cost of one pen. What is the combined cost of one notebook and one pen?
Answer:
$5.5
Step-by-step explanation:
6 * N (notebook) + 3 * P (pen) = 27
n = 1.5 +P
6 * (1.5 + P) + 3 * P = 27
9 +6p +3p = 27
9p = 18
p (pen): $2
N (notebook): $3.5
combined cost of 1 pen and 1 notebook: $2 + $ 3.5 = $ 5.5

A coordinate plane with a line passing through (negative 3, negative 4) and (5, 0).
Answer:
Graph D
Step-by-step explanation:
Look, I'm trying here, I tried the graphing calculator and it appeared as Graph D
The graph of the equation is a coordinate plane with a line passing through (-3, -4) and (5, 0). Option D is correct
Equation of a lineA line is the shortest distance between two points. The equation of a line in slope intercept form is expressed as y = mx + b
where:
m is the slopeb is the y-interceptGiven the equation x - 2y = 5
Write in slope-intercept form;
-2y = -x + 5
y = 1/2 x - 5/2
We need two points passing through the line, we will find the x and y-intercept
If x = -3
y = 1/2(-3) - 5/2
y = -3/2 - 5/2
y = -4
Hence one of the coordinate point is (-3, -4)
If x = 5
y = 1/2(5) - 5/2
y = 5/2 -5/2
y = 0
Hence one of the coordinate point is (5, 0)
Hence the graph of the equation is a coordinate plane with a line passing through (-3, -4) and (5, 0).

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB = 3 and AC = 9, what is the length of AD? (Note: the figure is not drawn to scale.)
Answer:
The length of AD is 1 unit
Step-by-step explanation:
Let us solve the question
In Δ ABC
∵ ∠B is a right angle
∵ BD is perpendicular to the hypotenuse AC
∴ (AB)² = AD × AC ⇒ rule
∵ AB = 3 units
∵ AC = 9 units
∵ AD = x
→ Substitute them in the rule above
∴ (3)² = x × 9
∴ 9 = 9x
→ Divide both sides by 9
∵ [tex]\frac{9}{9}[/tex] = [tex]\frac{9x}{9}[/tex]
∴ 1 = x
∴ The length of AD is 1 unit

Graph a line that has a slope of -3 and contains the point (4,-2)
Answer:
The equation of the line is:
[tex]y = -3x+10[/tex]
The graph is attached below.
Step-by-step explanation:
Given that the line has a slope of -3, so
m = -3
As the point contains the point (4, -2), so we can use the point-slope form of the line equation to determine the line.
Point slope form:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
so substituting the values m = -3 and the point (4, -2)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - (-2) = -3(x-4)[/tex]
[tex]y+2 = -3x+12[/tex]
[tex]y = -3x+12-2[/tex]
[tex]y = -3x+10[/tex]
Therefore, the equation of the line is:
[tex]y = -3x+10[/tex]

m∠1= 180° -52°
m∠1= 128°
m∠3= 47° (alt. ∠s)
m∠4 +47°= 180°
m∠4= 180° -47°
m∠4= 133°

the x-axis and then shifted 4 units down.
a. g(x) = 7x + 4
b. g(x) = -7x + 4
c. g(x) = 7x - 4
d. g(x) = -7x - 4
Answer:
d. g(x) = -7x - 4
Step-by-step explanation:
If it is reflected over the x-axis, there is a negative sign to the x term.
There is a shift of 4 units, so it is -4.
Change the word sentence into a mathematical equation. Tell what each variable represents.
1. A music club membership costs $17.00 and $7.00 per CD.
2. The total cost of a carpet is $3.00 times the number of square feet.
3. The amount of money you earn for allowance is $20 times the number of months.
4. The cost of belonging to a fitness club is $200 to join and $30 a month in membership dues.
Answer:
1. $17 + $7C.
This equation provides the total cost if you want to purchase a music CD along with a music club membership. C represents the amount of CDs you wish to purchase, and since each CD costs $7, the amount of money you would need to purchase C amount of CDs is $7C.
2. $3A.
This equation provides the total cost of the area of carpet you want to purchase. A represents the area of the carpet that you want to purchase, measured in square feet as provided by the question, and since each square foot costs $3, the total cost is $3A.
3. $20M.
This equation provides the total money you earn for allowance after M months. M is the number of months that have passed, and since you earn $20 for allowance every month, the total allowance you have earned is $20M.
4. $200 + $30M.
This equation provides the total cost for joining and staying in a fitness club for M months. The initial cost, $200, is applied no matter how many months you join, so we add it from the start; since each month, M, you have to pay $30, the total amount of membership dues is $30M.

Preston started the summer owing $15 to his brother and $20 to his sister. He earned $75 mowing lawns, and paid his brother and sister back what he owed them. Which expression represents the amount of money that Preston has after paying back his brother and sister?
Answer:
$75 - $15 - $20 = $40
Step-by-step explanation:
Given that:
Money owed by Preston to his brother = $15
Money owed by Preston to his sister = $20
Total money earned by Preston = $75
Now, the money is paid back that he owed to his sister and brother.
To find:
The expression to represent the amount of money left with Preston after clearing all his dues?
Solution:
Once Preston pays back the money that he owed to his brother and sister, he will not have all $75 left with him.
He will have lesser amount of money.
Money left with Preston = Total money earned by Preston - Money owed to brother - Money owed to sister
Putting the values given as per the question statement, we get:
Money left with Preston = $75 - $15 - $20 = $40
Therefore, the expression to represent the amount of money left with Preston = $75 - $15 - $20 = $40

Bir su deposunun 17/24 şu ile doludur depodaki suyun 80 litresi kullaninca deponun yarısı dolu oluyor buna göre deponun tamamı kaç litre su alir
Answer:
384 Litre
Step-by-step explanation:
Tankın alabileceği toplam su miktarı = x
(17/24) x - 80 Litre = 1 / 2x
Benzer terimleri toplayın
17 / 24x - 1 / 2x = 80 Litre
5 / 24x = 80 Litre
5x / 24 = 80 Litre
Çapraz Çarpma
5x = 80 Litre × 24
x = 80 Litre × 24/5
x = 384 Litre
Dolayısıyla tüm tankın alabileceği su miktarı 384 Litredir.
