Answer:
10 red marbles
Step-by-step explanation:

Probability of red= 2/9
Number of red= 45*2/9= 10
Answer:
y = 8x-3
Step-by-step explanation:
The sampling distribution standard deviation is the population standard deviation divided by the root of the sample size.
sampling distribution standard deviation = 6.00/√36 = 1.00
Answer:

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = -
x + 3 ← is in slope- intercept form
with slope m = - 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 
Answer:Only one triangle can be constructed
Step-by-step explanation:
According to the question sides given are 1m, 2m and 2m
For the possibility of a triangle the sum of the two sides must be greater
than the third side
We have 1+2>2
⇒3>2
Also 2+2>1
⇒4>1
So the possibility of a triangle is fulfilled
Only an isosceles triangle can be constructed
as two sides are equal
