The probability that either event A or B will occur is 43/60
Getting probability value :Using the parameters given
n(A) = 29
n(B) = 14
Total number of events = 29+17+14 = 60
The probability of each event :
P(A) = 29/60
P(B) = 14/60
P(A or B ) = P(A) + P(B)
P(A or B ) = 29/60 + 14/60
P(A or B ) = 43/60
Therefore, the probability of A or B is 43/60

(6d-5)-8(3/4d-1)
the 3/4 is a fraction. help please
Answer:
3
Step-by-step explanation:
The first step in simplifying this equation is multiplying out the 8 in front of the parentheses
(6d - 5) - 8(3/4d - 1)
(6d - 5) - (6d - 8)
Then multiply the minus sign, this is important to remember because it will cause the -8 to become + 8
(6d - 5) - 6d + 8
Combine like terms ( ie. 6d - 6d, -5 + 8)

A gardener has 640 feet of fencing to fence in a rectangular garden. One side of the garden is bordered by a river and so it does not need any fencing.
What dimensions would guarantee that the garden has the greatest possible area?
9514 1404 393
Answer:
160 ft (out from the river)320 ft (parallel to the river)Step-by-step explanation:
Let x represent the length of fence parallel to the river. Then the dimension of perpendicular to the river will be half the remaining fence: (640-x)/2. The total area will be ...
A = x(640-x)/2
This is the equation of a parabola that opens downward. It has zeros at x=0 and x=640, so its axis of symmetry is x = (0+640)/2 = 320. That is, the peak of the area curve is found when x=320.
The dimensions of the garden with the largest area are 160 ft wide by 320 ft long, where the long side is the river side.

The sum of two numbers is 52. The smaller number is 10 less than the larger number. What are the numbers?
Answer:
ta check the largest number to be x + 10 then the other number to be x then he quit x + 10 + x is equals to 52 collect the like terms x + x + 10 is equals to 52 2x + 10 is equals to 52 move channel to the equals sign so that it becomes 2 x is equals to 52 - 10 2 x is equals to 42 divide both sides by 2 x is equals to 21 so the largest number that was x + 10 now is 31 and the other number is 21
Answer:
The numbers are 21 and 31.
Step-by-step explanation:
For this problem, we have two unknowns which we can call x and y. To solve for two unknowns, we will need two equations so we can use it to substitute one of the unknowns.
We know that they add to 52 so we can write the equation:
x + y = 52
We also know that the smaller number is 10 less than the other one, so we can write the second equation:
y - 10 = x
Now we can use the second one to substitute for x in the first one and solve for y:
(y-10) + y = 52
Now we just need to solve it by simplifying and isolating the terms:
y-10 + y = 52
y+y - 10 + 10 = 52 +10
2y = 62
2y/2 = 62/2
y = 31
Now we can use either of the equations to solve for x now that we have y.
31 - 10 = x
x = 21
The numbers are 21 and 31.

Help with this question not sure why it’s confusing me
Answer:
see below
Step-by-step explanation:
We have two points, so we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -6- -6)/( 6-3)
= ( -6+6)/( 6-3)
= 0/3
= 0
The slope is zero
This means that it is a horizontal line ( the y value does not change)
Answer:
slope is 0, line is horizontal
Step-by-step explanation:
First we will have to find the slope
Slope is equal to: y2-y1/x2-x1 (rise/run)
So let's label the points
(3,-6), (6, -6)
x1=3
y1=-6
x2=6
y=-6
now plug those into the equation
-6-(-6)/6-3= 0/3=0
since the slope is equal to 0, that means the line is horizontal

Answer:
3.
Step-by-step explanation:
Since it states it needs to be cut into pieces, it's division, so since it's division we do KCF - keep change flip
We keep the first term, then we change the sign to a multiplication sign and flip the numerator and the denominator for the second term, so your equation would be :
6/8 × 4/1
6 times 4 would be 24, then we put 24 over 8, 24/8, - then you just divide 24 by 8 which would be 3. I hope this helps.

What is the number line?A horizontal line with evenly spaced numerical increments is called a number line. How the number on the line can be answered depends on the numbers present. The use of the number is determined by the question that if corresponds to, such as when graphing a point.
Descending order means arranging the numbers from largest to smallest.
Arranging the numbers in descending order:
B = 0.929
C = 0.844
A = 0.623
D = 0.062
Therefore, the numbers in descending order are B = 0.929, C = 0.844, A = 0.623, and D = 0.062.
