Answer:
35 - 2.4(7-5)
= (35/1)-(24/10)(7-5)
= [(35×10)/(1×10)]-(24/10)(2)
= (350/10)-(24/10)(2)
= (350-24)/10(2)
= 326/10(2)
= 32.6(2)
= 65.2
Thank you.
BY GERALD GREAT.
The correct answer is b), the probability of B occurring given A has occurred.
Jerry had a 3 in 10 chance or a 30 percent chance to hit area A randomly
Mu=80, sigma=39, X=85
Z=(X-mu)/sigma = 5/39=0.128=0.13
P(X<=85)= 0.5517 (from Z-table)
so, P(X>85)=1-0.5517=0.4483 approx. thats 44.8% probability.
Question that needs to be solved:You use 4 gallons of water on 30 plants in your garden. At that rate, how much water will it take to water 45 plants?=> 4 gallons is to 30 plants.=> 4 gallons / 30 plants = 0.13 gallons per plants.Now, it needs to water around 45 plants, let us solve how much will it need => 0.13 gallons * 45 plants = 6 gallons<span>Thus, to water 45 plants you need to have 6 gallons of water</span>
