There are 10 marbles in a bag .2 red, 5 green and 3 blue. Aron picks up 2 marbles without
replacing the first marble. What is the probability that both the marbles are blue.
Answer:
It would be 0.09
Step-by-step explanation:
First, note the original Probability for picking a blue marble in the first try:
0.3
Now, if this were to happen again, knowing that no marbles would be taken out, it would be another chance of 0.3 for Aron to pick up a blue marble on his second pick up.
Due to these being independent events, you can do:
0.3*0.3 = 0.09
To get your answer, 0.09.
Answer:
27/90 = 3/10
Step-by-step explanation:
Calculate the probability that neither is blue
7/10 * 6 / 9
63/90
Now the remainder of the choices are what the probability is when both are blue
1 - 63 / 90
27/90 is the probability of choosing 2 blues.

Answer:4.76
Step-by-step explanation:

The angle of inclination x of this ramp is 4.76 degrees.
What is a right-angle triangle?'A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any one angle is a right angle.'
According to the given problem,
Perpendicular = 1 inch
Base = 12 inches
Angle of inclination = x
We know,
tan (x) = [tex]\frac{Perpendicular}{Base}[/tex]
⇒ tan(x) = [tex]\frac{1}{12}[/tex]
⇒ x = [tex]tan^{-1} \frac{1}{12}[/tex]
⇒ x = 4.76 degrees.
Hence, we can conclude, the angle of inclination is 4.76 degrees.

What is the area of an equilateral triangle with the base of 8 cm? Round your answer to the hundredths place.
Step-by-step explanation:
[tex] \frac{{x}^{2} \times \sqrt{3}}{4} [/tex]
for x=8, area=16*root(3)
Answer:
Let's find the height:
Half of 8 is 4.
4^2 + 8^2 = 80
80(lets find the square root of 80): 8.944 ^2 = 79.995136 close enough to 80
Your new height is 8.944.
8 x 8.944 = 71.552, 71.552 x 1/2 (basically just dividing by 2) = 35.776 rounded would be = 35.78 cm^2
Formula of area of a triangle:
B(base)H(height) x 1/2(basically just dividing by 2)
In this case 8 is your base and 8.944 is your height.
7(2x - 8) = -2x + 8

Find the first 5 terms of the sequence
A(n)=n+A(n-1) a1 = 3
Answer:
A(1) = 3, A(2) = 5, A(3) = 8, A(4) = 12, A(5) = 17
Step-by-step explanation:
Given A(n) = n + A(n–1) a1 = 3.
A(1) = 3.
A(2) = (2) + A(2–1)
= (2) + A(1)
= (2) + (3) = 5
A(3) = (3) + A(3-1)
= (3) + A(2)
= (3) + (5) = 8
A(4) = (4) + A(4–1)
= (4) + A(3)
= (4) + (8) = 12
A(5) = (5) + A(5–1)
= (5) + A(4)
= (5) + (12) = 17

nope. bc...
0 ≠ 72 + 9.
yw!
Answer:
no.
Step-by-step explanation:
y (0) = 8(9) + 9

The graph of y = 7x + 56 passes
through (-5, 7a) in the standard(x, y)
coordinate plane. What is the value of a ?
Answer:
a = 3
Step-by-step explanation:
The point (- 5, 7a ) satisfies the equation
Substitute the coordinate points into the equation and solve for a
7a = 7(- 5) + 56 = - 35 + 56 = 21 ( divide both sides by 7 )
a = 3

Find the surface of the prism.
Answer:
520 yd^2
Step-by-step explanation:
The prism is a rectangular prism
2 * (14 * 5) + (5 * 10) + (14 * 10)= 520
Answer: 520 yards squared
Step-by-step explanation: The surface area is basically the area on every surface. So it’s (14x10)x2 + (14x5)x2 = 520 yards squared. Hope it helped! :)

A stack of identical 8-centimeter-by-10-centimeter rectangular playing cards is sitting on a table. The stack is 1 centimeter high and has a volume of 80 cubic centimeters. The table is bumped and the stack of cards is shifted so that the stack is no longer a right rectangular prism, but all of the cards are still part of the stack.
Which of the following statements are true of the shifted stack of cards? Select all that apply.
A) The shifted stack of cards has a volume of 80 cubic centimeters because it has the same base area and height.
B) The area of a card at any location in the stack remains the same.
C) The width of the stack from the leftmost edge to the rightmost edge will remain 10 centimeters because the volume is the same.
D) Cavalieri’s principle cannot be applied to the volume of the stack because the stack is a rectangular prism instead of a cylinder.
E) The area of the middle card in the stack is 40 square centimeters because it is half of 80.
Answer: A, B, C.
If the stack of cards are shifted so it is not straight, it still has everything the same.

Steve ran a 12-mile race at an average speed of 8 miles per hour. If Adam ran the same race at an average speed of 6 miles per hour, how many minutes longer did Adam take to complete the race than did Steve?
Answer:
the picture is the formula.
D stands for distance
S stands for speed
T stands for time
Step-by-step explanation:
Steve
Time = Distance divided by speed
=12miles divided by 8miles per hour
=1.5hours or 90minutes
Distance= 12miles
Speed= 8miles per hour
Adam
Speed= 6miles per hour
Distance= 12miles
Time= distance divided by speed
= 12miles divided by 6miles per hour
=2hours or 120minutes
120minutes - 90minutes=30 minutes
What is the mean absolute deviation and population standard deviation of this data set? 1, 4, 6, 7, 9, 9
Answer:
a)2.33
b) 2.83
Step-by-step explanation:
What is the mean absolute deviation and population standard deviation of this data set? 1, 4, 6, 7, 9, 9
Step 1
Find the Mean
n = 6
Mean = Sum of values/Number of value
= 1 +4 + 6 +7 + 9+ 9/6
= 36/6
= 6
a) Mean Absolute Deviation
Formula
= |x - Mean|/n
= | (1 - 6)+(4 - 6) + (6 - 6)+(7 - 6)+ (9 - 6) + (9 - 6)|/6
= 5 + 2 + 0 + 1 + 3 + 3/6
= 14/6
= 2.3333333333333
Approximately = 2.33
b) Population Standard deviation
Formula
=√(x - Mean)²/n
= √ (1 - 6)²+(4 - 6)² + (6 - 6)² +(7 - 6)² + (9 - 6)² + (9 - 6)²/6
= √25+ 4+0+ 1+ 9+9/6
= √48/6
= √8
= 2.828427125
Approximately = 2.83
