Answer:
= 18 red marbles
Step-by-step explanation:
Let x be the number of red marbles that must be added
Therefore;
New number or red marbles = x+12
Total marbles will be x+32
Thus;
The probability of selecting a red marble = (x+12)/(x+32)
Therefore;
(x+12)/(x+32)=3/5
5(x+12)=3(x+32)
5x+60+3x+96
2x=36
x=18
That's true! you can use the speed triangle to help you remember

Step-by-step explanation:
Area of a rectangle is given by:
....[1]
where
A is the area of rectangle
l is the length of a rectangle
w is the width of a rectangle.
As per the statement:
A certain rectangle has an area of 
⇒
Now factor this trinomial :

⇒
⇒
unit square
On comparing with [1] we have;
unit and
unit
Therefore,the length and width of the rectangle are:

Answer:
Independent
Step-by-step explanation:
Dependent Sampling:
Dependent sampling is one in which the individuals in one sample are used to determine the individuals in the other sample.
But the third dash graders are divided into two groups independent of each other.
So the sampling is independent.
It is qualitative because it is showing quality irrespective of the number of students .
Quantitative Sampling is one in which the results change with the number of the individuals / tests etc. But in this experiment the number of the students is fixed so it is showing quality rather than quantity.
Answer:
a) 36 seconds
6 divided by 10= 0.6
0.6=60% of a minute which equals 36
b) 15
10 minutes = 6 hot wings + 10 minutes = 6 hot wings + 5 minutes = 3 hot wings
(10+10+5 = 25 minutes)
