Well, the problem is that he does not replace the first marble after he draws it. Therefore, yes, he has a 2/12 probability of drawing a yellow marble first, but then he has a 4/11 probability of drawing a red marble second, not 4/12. This is because there are going to only be 11 marbles left in the bag after he draws the first marble and does not replace it.

The correct answer would be:
(2/12)(4/11)=8/132=4/66=2/33

Find the slope Y=5x+12
NikAS [45]

Answer: The slope = 5.

Step-by-step explanation:

The equation of a line in the slope -intercept form is given by :-

y=mx+c

,where  m= slope , c= y-intercept.

The slope of a line represents the rate of change of y with respect to x.

Given: Equation of line : Y= 5x+12

icang [17]

Answer:

-10 feet below the surface of the water

We are told that the dive rings position at the bottom of the pool is 10 feet below the surface of the water.

Now, an integer is basically a whole number that can either be be zero, positive or negative.

In this case, it's below the surface which means it's below zero.

Thus, it's negative.

So the integer is -10 feet below the water surface.

xz_007 [3.2K]

Answer:

D.A(n) = 250 + (n – 1)(0.03 • 250); $347.50

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=(14-1)=13\ years\\ P=\$250\\r=0.03

substitute in the formula above

A=\$250(1+0.03*13)

A=\$250(1.39)=\$347.50
