Note that [ (2x)^x ]^(1/x) = 2x, and that [ (2x)^(2x) ]^(1/x) = (2x)^2 = 4x^2

Multiplying these 2 results together, we get (2x)(4x^2) = 8x^3 (answer)

Answer:

Callie needs to hide both her and her brother's candy from him so that none is eaten/stolen.  Then count each stash separately.  Put the candies in groups of 10 to quickly establish that over 70 pieces were collected.  Callie should steal a stack from her brother's pile while he's not looking.  Just calmly shift one stack of ten candies to her side.  She should announce she got 47 pieces and her brother only 32.

forsale [732]

Answer: 0.9617

Step-by-step explanation:

Given : The proportion of adults use their phones in meetings or classes : p=0.57

Number of adults randomly selected : n= 9

Let x be the random variable that represents the number of adults use their phones in meetings or classes.

By using binomial probability formula, to find the probability of getting success in x trials.

P(x)=^nC_xp^x(1-p)^{n-x}

The probability that at least 3 of them use their smartphones in meetings or classes will be :-

P(x\geq3)=1-P(x

Hence, the required probability is 0.9617 .

castortr0y [4]

Answer:

x + 2y ≤ 100 and x + 3y ≤ 400

Maximum profit = 6x + 5y.

Step-by-step explanation:

Let there be x number of small dishes and y number of large dishes to maximize the profit.

So, total profit is P = 6x + 5y .......... (1)

Now, the small dish uses 1 cup of sauce and 1 cup of cheese and the large dish uses 2 cups of sauce and 3 cups of cheese.

So, as per given conditions,  

x + 2y ≤ 100 ........ (1) and  

x + 3y ≤ 400 .......... (2)

Therefore, those are the constraints for the problem. (Answer)
