If Mike does his mathematics homework today, the probability that he will do it tomorrow is 0.8. The probability that he will do
harina [27]

Answer:

d. 14:11

Step-by-step explanation:

There is a 7 in 10 chance that Mike does his homework today and a 8 in 10 chance he will do it tomorrow,  the probability that he will do it both today and tomorrow is:

P = \frac{7}{10}* \frac{8}{10}\\P=\frac{56}{100}=0.56

The odds are the probability that an event occurs over the probability that it does not occur:

Odds = \frac{0.56}{1-0.56}=\frac{56}{44}=\frac{14}{11}

The odds that he will do it both today and tomorrow are 14:11.

At the rate of $2.00 per square foot the cost of painting the rectangular board with a semicircular top shown in the figure is $
Elenna [48]
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
<span> 
it consists of a rectangle, dimensions  L = 4ft and W = 3ft = Ar = 4ft x 3ft = 12 ft^2

</span>then, you have one half of the area of the circle that has diameter  R = 3ft - radius will be r = 1.5ft the area of that half will be:

Ac = r^2 \pi/ 2
= (1.5 ft)^2 x 3.14 / 2
= 2.25 ft^2 x 3.4/2 
= 7.065 ft^2/ 2 
= 3.5325ft^2

A = Ar + Ac
A = 12ft^2 + 3.5325ft^2
A = 15.5325ft^2

<span>At the rate of $2 per square foot, the cost will be: 
$ 15.5325*2 = 31.07 </span>
