A bag with 10 marbles has 2 yellow marbles, 4 blue marbles, and 4 red marbles. A marble is chosen from the bag at random. What is the probability that it is yellow?
Answer:
P(Y) = 2/10 = 1/5
Step-by-step explanation:
From the above question:
Total number of marbles = 10 marbles
Number of yellow marbles = 2 yellow marbles
Number of blue marbles = 4 blue marbles
Number of red marbles = 4 red marbles.
The probability of choosing a marble that is yellow is calculated as:
= P(Y) = Number of yellow marbles/Total number of marbles
P(Y) = 2/10
P(Y) = 1/5
9p²-?p+49
In order for the following expression to be a perfect square trinomial, fill in the missing number
Answer: ? = 42
Step-by-step explanation:
(a-b)² = a² - 2ab + b². From 9p² -?p + 49 we see
9p² = (3p)² and 49 = 7² Then Middle term is -2·(3p)·7 = -42p

Answer:
∠ ZWV = 39°, ∠ ZVW = 64° , x = 1
Step-by-step explanation:
∠ ZWV = ∠ ZYX = 39° ( alternate angles )
∠ ZVW = ∠ ZXY = 64° ( alternate angles )
The diagonals bisect each other , so
YZ = ZW

A hovercraft takes off from a platform. It's height (in meters), x seconds after takeoff, is modeled by h(x)=-(x-11)(x+3) How many seconds after takeoff will the hovercraft land on the ground?
Answer:
11seconds
Step-by-step explanation:
Given the height of the hovercraft expressed as;
(x)=-(x-11)(x+3)
The height of the hovercraft on the ground is 0, hence;
0 =-(x-11)(x+3)
-(x-11)(x+3) = 0
Multiply both sides by minus
(x-11)(x+3) = 0
x-11 = 0 and x+3=0
x = 11 and -3
Since time cannot be negative, hence the hovercraft will land after 11seconds
What is the surface area of a cylinder that has the following measurements?
area of each base: 50.24 ft2
area of lateral surface: 75.36 ft2
height of cylinder: 3 ft
Choices:
150.72 ft2
175.84 ft 2
125.6 ft2
128,6 ft 2
ASAP
Answer:
175.84 ft 2
Step-by-step explanation:
50.24 x 2 = 100.48
100.48 + 75.36 = 175.84
The surface area of the cylinder will be 175.84 square feet.
What is surface area?The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called as the surface area.
It is given that:-
Area of each base: 50.24 ft2
Area of lateral surface: 75.36 ft2
Total surface area = (Area of each base x 2 )+ Area of the lateral surface
Total surface area =( 50.24 x 2 )+ 75.36
Total surface area = 175.84 square feet
Hence the surface area of the cylinder will be 175.84 square feet.

Colleen divided integer a by −6 and got 6. Then she divided 6 by integer b and got −3. Find the quotient of integer a an integer b.
Answer:
12
Step-by-step explanation:
What Colleen did first: a / -3 = 8
Multiply each side by -3 : a = -24 <= now we know integer 'a'
What she did next: 8 / b = -4
Multiply each side by 'b' : 8 = -4 b
Divide each side by -4 : -2 = b <== now we know integer 'b'
The quotient a / b = -24 / -2 = 12

The ratio of the weights of A and B is equal to the ratio of the weights
of C and D. If A is 20 kg, B is 24kg and C is 40 find out the value of D .
Answer:
D = 48kg
Step-by-step explanation:
The ratio of the weights of A and B is equal to the ratio of the weights
of C and D.
From the above question
A : B = C : D
This can also be interpreted as
A/B = C/D
A is 20 kg
B is 24kg
C is 40kg
D is ?
Therefore:
20/24 = 40/D
Cross Multiply
20D = 24 × 40
D = 24 × 40/20
D = 48
Therefore, D = 48kg

Answer:
Solution given:
we have
f(x)=x²-9x-36
let
y=x²-9x-36
when
x=0
y=-36
when
y=0
0=x²-9x-36
x²-12x+3x-36=0
x(x-12)+3(x-12)=0
(x-12)(x+3)=0
either
x=12
x=-3
So,
x and y intercepts are (-3,0)(12,0) and 0,-36)

Carlo and his brother, agreed to buy a bicycle by sharing out the cost. The ratio of the amount of money paid by Carlo to that paid by his brother was 5: 2. The bicycle cost P3500. Find the amount paid by each of them.
Answer:
Carlo paid 2500 dollars and his brother paid 1000 dollars
Step-by-step explanation:
Given -
The ratio of cost shared by Carlo and his brother is 5:2
Which means Carlo paid 5/7th part of the total cost of bicycle
5/7 * 3500 = 2500 dollars
The amount paid by his brother is 3500 - 2500 = 1000 dollars

Given that events A and B are independent with P(A)=0.5 and P(B)=0.15, determine the value of P(A∣B), rounding to the nearest thousandth, if necessary.
The value of the independent variable probability is P ( A | B ) = 0.5
Given data ,
Let the independent events be represented as
P ( A ) = 0.5
P ( B ) = 0.15
Now , the value of the probability P ( A | B ) is given by
And , if events A and B are independent, then P(A|B) = P(A). Therefore, in this case, P(A|B) = P(A) = 0.5
Hence , the probability is P ( A | B ) = 0.5

NO LINKS I NEED A REAL ANSWER!!!!!!
Answer:
the diagonal distance from one corner to the opposite is 15 feet.
Step-by-step explanation:
using the pythagorean theorem, we know that a^2 + b^2 = c^2. if a=9 and b=12 we can set up our equation as follows:
9^2 + 12^2 = c^2
81 + 144 = c^2
225 = c^2
the square root of 225 is 15 therefore:
15 = c
