A teacher has a bag of marbles. There are 10 red, 10 blue, 8 green, 8 purple, and 8
yellow marbles in the bag. As the students enter the classroom, they draw a marble
and keep it. If the first student in the room draws a yellow, and the second draws a
blue, what is the probability that the third student will draw a green?

Step-by-step explanation:
(8/42) * 100 = 19%
Thenks and mark me brainliest :))
Answer:
The probability that the third student will draw a green is 19%.
Step-by-step explanation:
Definition of Probability Probability means possibility of occurrence. It is a branch of mathematics which deals with the occurrence of particular event out of some random events.Given marbles 10 red, 10 blue, 8 green, 8 purple, and 8 yellow marbles .
Therefore total marbles will be 44.
Since the first student in the room draws a yellow, and the second draws a blue ,thus remaining marbles will be 42.
So, the probability that the third student will draw a green is [tex]\frac{8}{42}[/tex]×[tex]100\\[/tex] = 19%

Which equation represents the linear relationship between x and y that is shown in the
table below?
Answer:
y= 5-x
Step-by-step explanation:
We notice that when we put 5 for x we get 0 which means that we must be subtracting the given x value by constant
y= 5-x makes sense, try plugging in any x value given in table and you will get its y counterpart back.
For eg, when x= -1
y= 5- (-1) = 6 (negatives add)

Answer:
The height of the square pyramid is 24 unit.Step-by-step explanation:
Given that:
Edge of the square pyramid = 14 unit Slant height of the square pyramid = 25 unitTo Find:
The height of the square pyramid.We know that:
In pythagoras theorem.
H² = P² + B²Where,
H = Hypotenuse = 25 unitP = Height = Let xB = Base = 14/2 = 7 unitFinding the height of the square pyramid:
⇒ H² = P² + B²
⇒ (25)² = x² + (7)²
⇒ 625 = x² + 49
⇒ x² = 625 - 49
⇒ x² = 576
⇒ x = √576
⇒ x = 24
Hence,
The height of the square pyramid = 24 unitfind a:c and a:b:c of a:b =4:5, b:c=3;5
pls ans with explanation
Here's the solution,
a : b = 4 : 5
b : c = 3 : 5
now, we can combine the ratios if the value of b is equal in both of them, and we have to make sure it's the minimum value since we have to obtain it in the simplest form, so let's take the L.C.M of b in both proportions .
L.C.M of b in both ratios is 15
so
ratio 1.)
a : b = 4 : 5 a : b = 12 : 15( just multiplied both numbers by 3 to make b = 15 )
ratio 2.)
b : c = 3 : 5b : c = 15 : 25( just multiplied both numbers by 5 to make b = 15)
now, simply combine the equations to get,
a : b : c = 12 : 15 : 25
and hence,
a : c = 12 : 25
What is the distance between two points(0,0)(-3,5)
Step-by-step explanation:
Think of it like a right triangle. Do you have a graph handy?
Ok, graph both of the points. Now connect the points. That's our hypotenuse and the side length we want to find.
Now, bring down a line from (-3,5) to the x axis. Do you see a right triangle?
All we have to do is find the hypotenuse of this right triangle we just drew. We already have the leg lengths which are 3 and 5. Using this, do the pythagorean theorem.
9+25=34
√34 is our hypotenuse & distance between the points

Answer:
y>x-2
Step-by-step explanation:
When we see an inequality on a coordinate plane, we first treat it like a linear equation. The red inequality, or the red line, clearly has a positive slope. One can assume that this slope is 1. This line is also 2 units down, making the inequality x-2. There you have it!
Furthermore, we can tell it is the 1st choice because the line is dashed. In inequalities, the line is only dashed when the inequality contains < or >. Also, the shading is "above" the line, meaning the y must be greater than the line.

Answer:
Lisa's new area will be 3600 ft ^ 2
It will be 9 times the original
Dan should increase the length by 5 times
Step-by-step explanation:
Original length = 40
New length = 40 x 3 = 120
Original length = 10
New length = 10 x 3 = 30
120 x 30 = 3600 ft^2
3600/400 = 9
It will be 9 times larger
For Dan:
ex:
length = 1
width = 2
Area = 2
He wants it to be 20 times 2
Lisa says increase 4 times
2 x 4 = 8
2 x 20 = 40
40/8 = 5

Joe and Steve went to a chocolate shop and got some fudge. The fudge cost $32 per kilogram. Joe ordered 75 grams of fudge. Steve ordered 235 grams of fudge. How much did each person pay? How much MORE did Steve pay than Joe?
Answer: Joe paid $2.4; Steve paid $7.52
Steve paid $5.12 more than Joe
Step-by-step explanation:
Cost of I Kg fudge = $32
But we know that 1 kg =1000g
That is to now say that
Cost of 1000g of fudge = $32
a)
If Joe ordered 75 grams of fudge then he paid
Now 1000g of fudge = $32
75g of fudge will cost =75 x 32 /1000 =$2.4
also .
b) 235 grams of fudge ordered by Steve will cost
235 x 32 / 1000=$7.52
Therefore, Steve paid $5.12 ($7.52-$2.4) more than Joe

llHappiest♡Writerll4) A zoologist was checking the weights of three gorillas. Gorilla A weighed 559 pounds, gorilla B weighed 827 pounds and gorilla C weighed 130 pounds. What is the combined weight of all three gorillas?
Answer:
1,516 pounds
Step-by-step explanation:
Gorilla A weighed = 559 pounds Gorilla B weighed = 827 pounds Gorilla C weighed = 130 pounds
Total weight of the gorillas = gorilla A + gorilla B + gorilla C
= 559 pounds + 827 pounds + 130 pounds
= 1,516 pounds
