Answer:

36 people would order chicken.

Step-by-step explanation:

Case I: (50 People in Total)

Total Number of People Ordering=8+10+18+14=50

Percentage of People ordering chicken=people ordering chicken/total number of people=18/50=0.36%

Case II: (100 People in Total)

Number of People ordering chicken=percentage of people ordering chicken x total number of people=0.36 x 100=36

The clouds are 226.68 meters above the spotlight.

Step-by-step explanation:

Step 1:

The angle measuring device is 65 meters from the spotlight and the angle of elevation from the ground to the spot of light is 74°.

So a right-angled triangle can be formed using these measurements. The angle of the triangle is 74° while the opposite side of the triangle measures x meters while the adjacent side of the triangle measures 65 meters.

We need to calculate the opposites side's length of the triangle.

Step 2:

Since we have the adjacent side's length and need to calculate the opposite side's length we use the tan of the given angle.

The opposite side of the triangle = x meters.

\tan \theta = \frac{oppositeside}{adjacentside} = \frac{x}{65}.

tan 74 = 3.487, x = 3.487(65) = 226.07.

So the spot of light is 226.07 meters above from the spotlight.

1. Many Alpine ski centers base their calculations of revenues and profits on the belief that the average skier ski’s four times
pshichka [43]

Answer:

We cannot infer at the 10% significance level that the assumption of ski centers is wrong

Step-by-step explanation:

The null hypothesis for this question can be stated as  

Null hypothesis H0:  =4  

Alternate hypothesis Ha:  

The test is two tailed

Standard Deviation –  

 = 2

z=(4.84-4)/(2/sqrt(63))

=3.33

Z(0.1/2)=1.645 is less than Z =3.334

Hence, we will reject H0  

Hence, the average growth skier ski’s four times a year is not true

PLEASE HELP ME OUT WITH THIS, WILL MARK BRAINLIEST<br><br> 50PTS
spayn [35]

Answer:

E

Step-by-step explanation:

Let's say "s" represents the number of steps you still need to take to achieve your goal of at least 12,100 steps. You've already walked 5204 steps, and if we add this to s, we should get a total of <em>at least</em> 12,100 steps:

s + 5204

The words "at least" means that we need to use ≥, so:

s + 5204 ≥ 12,100

The answer is E.

If we were to solve this inequality:

s + 5204 ≥ 12,100

s ≥ 6896

In other words, you still have to take at least 6896 more steps.
