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.

A car travels 60 kilometers in one hour before a piston breaks, then travels at 30 kilometers per hour for the remaining 60 kilo

Varvara68 [4.7K]

Answer:

Total Distance : 1*60 +60=120

Total time taken = 1+ 60/30= 1+2=3

Hence average speed for the trip = 120/3= 40 kmph

Hence Answer is 40

2. The logo shown below was created by splitting a circle into 6 equal sections. Raphael is creating a stage-sized version of th

andrew11 [14]

From the shaded diagram, Raphael will need 3 of the 6 equal portions, or exactly 1/2 of the area of the circle. Given a radius of 12 ft, knowing that the area of any given circle is $\pi r^2$ , and knowing that the area of the fabric needs to be half of the total area, we can set up the equation for the area of the fabric $A$ :

$A= \frac{1}{2}\pi (12)^2$

Simplifying, we find that the area of the fabric is exactly

$\frac{1}{2} \pi (144)= \frac{144}{2} \pi=72\pi$ ft.² Using the approximation of 3.14 for π, we get an area of approximately $72(3.14)=226.08$ ft² of fabric.
