### Answers

Cost of meal before tip + 15% = $99.50 Adding 15% is equal to multiplying by 1.15 Cost of meal before tip x 1.15 = 99.5 This can be rearranged to give; Cost of meal before tip = Cost of meal before tip =$86.52
Each meal was $9.95 a peice aND EACH HAD TO pay$1.50 on the tip

Evaluate the summation of 2 n plus 5, from n equals 1 to 12.. A. 29
B. 36
C. 216
D. 432

### Answers

Answer:

Option: C is the correct answer.

C.  216

Step-by-step explanation:

We are asked to evaluate the sum of the following summation:

Now, this summation could also be written as:

i.e.

Now, we know that:

Since,

i.e.

and

Hence, we have:

i.e.

i.e.

the correct answer is C)216 / Let f(n) = 2n + 5. Then we must simply calculate (f1), f(2), ..., (f12). And we have that f(1) = 2*1 + 5 f(1) = 7; f(2) = 2*2 + 5 f(2) = 9; f(3) = 2*3 + 5 f(3) = 11. And so on. It's easy to see that the rest of the results will be 13, 15, 17, 19, 21 and so on. So the summation will be S = 7 + 9 + 11 +... + 29 S = 216

An exponential random variable has a standard deviation of 16. Calculate The probability that it takes on a value < 11. Use 3 decimal places.

### Answers

Answer:

And using the cdf we got:

Step-by-step explanation:

Previous concepts

The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:

0" alt="P(X=x)=\lambda e^{-\lambda x}, x>0" align="absmiddle" class="latex-formula">

And 0 for other case. Let X the random variable that represent the random variable of interest and we know that the distribution is given by:

We know the variance on this case given by :

So then the deviation is given by:

And if we solve for we got:

The cumulative distribution function for the exponential distribution is given by:

Solution to the problem

And for this case we want to find this probability:

And using the cdf we got:

Roses 7
Carnations 5
Total 12 96

The ratio of roses to carnations is 7 to 5. If 96 flowers are needed for table decorations, ______ roses and ______ carnations are needed.

### Answers

Step-by-step explanation:

Let the common multiplier of the given ratios be x.

Therefore, no. of roses = 7x & no. of carnations = 5x

According to the given information:

Thus,

Number of roses = 56

Number of carnations = 40
