A hotel has 480 rooms. Of these rooms,
are non-smoking. How many rooms are smoking?

Answers

Answer 1

Answer:

The number of smoking rooms [tex]N_s = \frac{480(100-x)}{100}[/tex], in which x is the percentage of non-smoking rooms.

Step-by-step explanation:

We are given a percentage of rooms that are non smoking, lets say x%, and (100-x)% will be smoking rooms. The number of rooms which are smoking is the total number of 480, multiplied by (100-x) and divided by 100.

Then:

[tex]N_s = \frac{480(100-x)}{100}[/tex]

Need Help With My Geometry Work Plz Help

Answers

Answer:

Step-by-step explanation:

(number of sides-2)*180 = (6-2)*180 = 720°

a= 720/6= 120°

lines form 180° angles

b= 180-120= 60°

sum of angles in a triangle is 180, and the angles are ≡

c=180/3 = 60°

c and d are supplementary angles (they add to 180)

d= 180-60 = 120°

d ≡ e+e because are vertical angles

e= 120/2 = 60°

sum of angles in a triangle is 180

f= 180 -90-60 = 30°

(number of sides-2)*180 = (5-2)*180 = 540°

g= 540/5= 108°

The cost of a shirt decreases by 18%. After the discount, the shirt costs $61.91. How much did the shirt cost before the
discount?

Answers

Answer:

$75.5

Step-by-step explanation:

The first step is to calculate the percentage decrease

= 100-18

= 82%

Therefore the original cost of the shirt before the discount can be calculated as follows

= 82/100 × x = 61.91

= 82x/100= 61.91

Cross multiply

82x= 100×61.91

82x= 6191

x = 6191/82

= 75.5

Hencd the original cost of the shirt is $75.5

Answers

Answer:

H0 : the treatment has no effect

Step-by-step explanation:

The test is formulated as hypothesis . Here the test ist that whether the treatment has  affected or not . So the null hypothesis can be formulated as

H0 : the treatment has no effect

against the claim

Ha: the treatment has an effect.

The null hypothesis  is the test performed and the alternate hypothesis is the claim against the test. Therefore they are opposite of each other.

Five candy bars and two cupcakes cost $12. Three candy bars and three cupcakes cost $11.25. Find the cost of each item

Answers

Answer:

$23.25

Step-by-step explanation:

12+11.25

Answer:

candy bars = a

cupcakes = b

a=1.5$

b=2.25$

Step-by-step explanation:

candy bars = a

cupcakes = b

1)5a+2b = 12

2)3a + 3b = 11.25

We can understand

3a + 3b = 3(a+b)= 11.25

a+b = 11.25÷3 = 3.75

from No.2 equation.

than we do

(5a+2b) - 2(a+b)

and we got 3a

so

12 - 7.5 = 4.5 = 3a

a=1.5$

b=2.25$

The capacity of a water tank is 1000 litres. If 7/10 parts of the tank is emptied, how many litres of water are left in the tank?​

Answers

Answer:

300litres

Step-by-step explanation:

capacity of water tank=1000litres

7/10 parts of tank is emptied,

method 1

so, to know the litres of water left in the tank has to be equal to 1000litres-emptied tank

let X to represent water left in the tank

X=1000litres-(7/10*1000litres)

X=1000litres-700litres

X=300litres

hence, litres of water left in the tank =300litres

method 2

since, full tank is 10/10 and you know the emptied tank has 7/10. meaning the remaining part of water is

10/10-7/10

3/10 of the tank with water

therefore, 3/10*1000litres

300litres.

The rate at which a chemical decomposes is increasing at a continuous 6.6 % % . What is the actual hourly percent increase

Answers

Answer:

the actual hourly percent increase is 6.823 %

Step-by-step explanation:

Given that data in the question;

rate chemical decomposes increasing continuously at 6.6 %,

r = 6.6% = 0.066

actual hourly percent increase = ?

Now,

hourly percent increase = ( [tex]e^r[/tex] - 1 ) × 100%

we substitute

hourly percent increase = ( [tex]e^{0.066[/tex] - 1 ) × 100%

hourly percent increase = ( 1.06823 - 1 ) × 100%

hourly percent increase = 0.06823 × 100%

hourly percent increase = 6.823 %

Therefore, the actual hourly percent increase is 6.823 %

134-86=48
1/5 • 48/134 =0.0716
0.0716•100=7.16
when rounded you get 7%

The probability that when she opens a random picture from the computer folder, it will be a blurry picture she took with her cell phone is 7%.

What is probability?

Probability is the likelihood or tendency that something will occur.

Probablility of blurry picture=(134-86)×0.2/134

Probablility of blurry picture=48×0.2/134

Probablility of blurry picture=9.6/134×100

Probablility of blurry picture=7.16

Probablility of blurry picture=7% (Approximately)


Thus, the probability that when she opens a random picture from the computer folder, it will be a blurry picture she took with her cell phone is 7%.

The daily stock price for International Business Machines (IBM) historically has followed an approximately normal distribution (when adjusting for inflation) with a mean of $143.311 and standard deviation of $3.9988 Approximately 38.34% of days IBM had a stock price greater than what dollar amount

Answers

Answer:

Greater than $144.49.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of $143.311 and standard deviation of $3.9988.

This means that [tex]\mu = 143.311, \sigma = 3.9988[/tex].

Approximately 38.34% of days IBM had a stock price greater than what dollar amount?

Greater than X when Z has a p-value of 1 - 0.3834 = 0.6166, so X when Z = 0.295.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.295 = \frac{X - 143.311}{3.9988}[/tex]

[tex]X - 143.311 = 0.295*3.9988[/tex]

[tex]X = 144.49[/tex]

Greater than $144.49.

To estimate the mean length of rattlesnakes, 10 such snakes are randomly selected. Their lengths, in inches, are as follows: 40.2 43.1 45.4 44.5 39.5 40.2 41.0 41.6 43.1 44.9 Find a 90% confidence interval for the mean length of all rattlesnakes.

Answers

Answer:

The confidence interval will be "41.04, 43.81".

Step-by-step explanation:

Given that,

Sample size,

n = 10

Sample total,

423.5

Sample mean,

[tex]\bar X =\frac{423.5}{10}[/tex]

   [tex]=42.35[/tex]

Sample variance,

[tex]s = \sqrt{4.5894}[/tex]

  [tex]=2.1423[/tex]

[tex]df=n-1[/tex]

   [tex]=9[/tex]

[tex]t^*=18331[/tex]

Now,

The margin of error will be:

⇒ [tex]E=\frac{s\times t^*}{\sqrt{n} }[/tex]

       [tex]=\frac{2.1423\times 1.8331}{\sqrt{9} }[/tex]

       [tex]=\frac{3.928}{3 }[/tex]

       [tex]=1.309[/tex]

hence,

The 90% confidence level will be:

= [tex](\bar X-E),(\bar X+E)[/tex]

By substituting the values, we get

= [tex](42.35-1.309),(42.35+1.309)[/tex]

= [tex](41.04),(43.81)[/tex]
