The Falcons’ starting running back injured his knee in last week’s game. There is a 35% chance that he will play in the next game. If he can play in the next game, he will likely rush 80 yards. If he does not play, the backup running back will likely rush 60 yards. Find the
Let X denote the rush
X = 80 with a probability of 0.35
and X = 60 with a probability of 0.65
Expected value:
E(X)=80*0.35 + 60*0.65 = 67

- solve with steps Three different machines A1, A2, A3 were used for the producing a large batch of similar manufactured items. Suppose that 10% of items are produced by machine A1, 20% by A2 and 40% by A3. Suppose further that 1%of the items produced by A1, 2% by A2 and 3% by A3 machine are defective. Suppose one item is selected from the entire batch and it is found to be defective. Calculate the probability that this item was produced bymachine A2A hacker breaking into a computer system has a 15% chance of breaking into a system in 2 minutes, a 25% chance after 5 minutes, and a 60% chance after 20 minutes.

If 45 more 6B pencils are put in the bag, the probability of randomly picking a 6B pencil now will be quadruple that of the previous probability of picking a 6B pencil. With the given information, evaluate the original number of 6B shade in the pencil bag.

Determine the number of points the team can expect to score.
- You believed that sending positive thoughts to your classmates that have been so much bothered with virtual classes will change their performance. You got their prelim grades before you send them bunch of thoughtful messages then got their midterm grades. Did your positive messages somehow made difference in their performance?AJ’s sleep pattern had been fluctuating due to stress and diet, so he started to keep a diary of how many hours he slept each night. On the 4th night after he started the diary, AJ slept 9.4 hours, which was the most sleep he got any night. Gradually, he got less sleep each successive night until, on the 18th night after he started the diary, AJ slept 6.2 hours, which was the least sleep he got any night. After keeping his diary for 6 months, he realized that the number of hours he got each night followed a sinusoidal curve. Let t be the number of nights since he started his diary, and s be how many hours he slept that night. It may be helpful to draw a crude sketch of the sleep time function and label the known t − and s − values on it. POSITIVE or NEGATIVE SIN or COS Maximum s − value = Minimum s − value = ______________ ______________ Middle s − value = ______________ = D Amplitude = ______________ = A ⇒ B = ______________ Given the crude sketch of the height function, the…Please solve practice question 2 and show the steps for the required areas.
