1.  This probability is 1/2*1/2=1/4, or 0.25.
2.  There are three ways to do this: draw two 2s, a three then a two, or a two then a three.  So our probability is 3/16=.1875.
3.  We already calculated the probability that the sum is less than 6.  Using similar methods, we calculate that there are three ways for a sum to be greater than 8, so our probability is 6/16=0.375.

Solve each equation check your solution<br> 2(3b-1)=40
vitfil [10]

Answer:

b=7

Step-by-step explanation:

2(3b-1)= 40

divide both sides by 2

3b-1 = 20

then add 1 to each side

3b = 21

then divide both sides by 3

b = 7

then check 2(3*7-1) = 40

A circular oil slick is expanding at a rate of 3m/min. How fast is the area of the oil slick changing when the diameter is 48 me
olga55 [171]

Answer:

48\pi \:m/min

Step-by-step explanation:

Diameter = 48 m

Therefore radius r = 48/2 = 24 m

Area  \: of \:  circular  \: oil  \: slick  \\ A = \pi {r}^{2}  \\  differentiating \: w \: r \: to \: t \: on \: \\  both \: sides \\  \\  \frac{dA}{dt} =  \frac{d}{dt} (\pi {r}^{2} )\\  \\  \frac{dA}{dt} =\pi  \frac{d}{dt} {r}^{2} \\  \\  \frac{dA}{dt} =\pi  \times  2{r}\\  \\  \frac{dA}{dt} =2\pi {r} \\  \\   \bigg(\frac{dA}{dt} \bigg)_{r=24} =2\pi \times  {24} \\  \\   \bigg(\frac{dA}{dt} \bigg)_{r=24} =48\pi  \: m \: per \: min
