Answer:

201

Step-by-step explanation:

The computation is shown below:

Given that

$= \sqrt{2704} \times 2^2 - \sqrt{49}$

= 52 × 4 - 7

= 208 - 7

= 201

Here we assume that V denotes the square so according to this we solve the given situation

After solving this, the answer is 201

mestny [16]

Percentage of Lemonade = 100 - (15 + 5)
= 100 - 20 = 80%

Now, We have to calculate the 80% of total amount of the drink i.e., 300 ml

So, 300 * 80%
= 300 * 0.80 [ 80% = 0.80 ]
= 240

In short, Your Answer would be: 240 ml

Hope this helps!

Answer:

You would expect for 35 people to have consumed alcoholic beverages.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they consumed alcoholic beverages, or they did not. The probability of a person having consumed alcoholic beverage is independent of any other person. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The expected value of the binomial distribution is:

$E(X) = np$

We learned in Exercise 3.25 that about 70% of 18-20 year olds consumed alcoholic beverages in 2008.

This means that $p = 0.7$

We now consider a random sample of fifty 18-20 year olds.

This means that $n = 50$

How many people would you expect to have consumed alcoholic beverages

$E(X) = np = 50*0.7 = 35$

You would expect for 35 people to have consumed alcoholic beverages.

Answer: 113.0 ft (bottom right corner)

=====================================

Explanation:

The triangle has a horizontal leg of 220 ft and a vertical leg of x ft. We'll use the tangent rule to connect the opposite side and adjacent side

opposite side = x
adjacent side = 220
this is with the reference angle shown in the diagram

So,
tan(angle) = opposite/adjacent
tan(26) = x/220
220*tan(26) = x
x = 220*tan(26)
x = 107.301169 ... see note below
x = 107.3

Now that we know the approximate value of x, we add on 5.7 to get
x+5.7 = 107.3+5.7 = 113.0

note: make sure your calculator is in degree mode. The value is approximate to 6 decimal places
