Answer:

540 ft² ; 60 yd²

Step-by-step explanation:

1 square yard = 9 ft²

Dimension of room:

24ft 0in by 22ft 6in

1 in = 1/12 ft

6in = (1/12) * 6 ft = 0.5 feet

Hence, Dimension of room in feet ;

24ft by 22.5 ft ;

Square feet of ceiling tiles; (24 * 22.5)ft² = 540ft²

Square yards of carpet needed :

1 yd² = 9 ft²

Let yd² of carpet needed = x

1 yd² = 9 ft²

x yd² = 540 ft²

Cross multiply ;

9x = 540

x = 540 / 9

x = 60

Hence, 60yd² of carpet is needed

Answer:

49.85% of light bulb replacement requests numbering between 37 and 61

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 37, Standard deviation = 8

Using the empirical (68-95-99.7) rule, what is the approximate percentage of light bulb replacement requests numbering between 37 and 61

37 is the mean

61 = 37 + 3*8, so 61 is three standard deviations above the mean

The normal distribution is symmetric, which means that 50% of the measures are above the mean and 50% are below.

By the Empirical Rule, of the 50% of the measures that are above the mean, 99.7% will be between the mean of 37 and three standard deviations above the mean, which is 61. So, this percentage is:

0.5*0.997 = 0.4985 = 49.85%

Answer:

B

Step-by-step explanation:

Apply slope intercept form, y2-y1 / x2 - x1. -6 is y2, -2 is x2, 5 is y1, and -2 is x1.

-6 - 5 / - 2 - (-2)

-11 / -2 + 2

-11 / 0

0

The slope is 0. B is your answer. I hope this helps you!

Step-by-step explanation:

Answer:

y = 95° and x = 21°

Step-by-step explanation:

y + 85° = 180° { being co-interior angles }

y = 180° - 85°

y = 95°

y = 4x + 11°[ being vertically opposite angles ]

95° = 4x + 11°

4x = 95° - 11°

4x = 84°

x = 84° / 4

x = 21°

Answer:

Step-by-step explanation:

surface area of the given image

= 1/2 (24) 35 (2 sides)  = 840 cm²

= 44 x 37 (2 sides)       = 3256 cm²

= 24 x 44 (bot base)   = 1053 cm²  

total                             = 5152 cm²          

Answer:

the lines are perpendicular to each other

Step-by-step explanation:

The standard form of equation of a line is y = mx+c

m is the slope of the line

c is the intercept

Given the equations

10x – 3y = 3

3x + 10y = 30

Get the individual slopes

For 10x – 3y = 3

Rewrite in standard form

-3y = -10x + 3

y = 10/3 x - 3/3

y = 10/3 x  - 1

Slope of the line is 10/3

For the equation 3x + 10y = 30

10y = -3x+30

y = -3/10 x + 3

Slope of the line is -3/10

Take the product of the slopes

10/3 * -3/10 = -1

Since the product of their slopes is -1, hence the lines are perpendicular to each other

Answer:

B 12.375 is the answer

Step-by-step explanation:

Key skills needed: Fraction to Decimal Conversion

1) The mixed number that is in the question is --> [tex]12\frac{3}{8}[/tex]

2) We need to find 12 and 3/8 as a decimal.

[tex]12\frac{3}{8}= 12 + \frac{3}{8}[/tex]

This means it would be 12."something"

We need to find out what [tex]\frac{3}{8}[/tex] as a decimal is.

3) To do this, we do 3 ÷ 8 (to find the decimal form of a fraction, you do the numerator divided by the denominator).

4) Check the image I posted to see how I did 3 ÷ 8.

5) Well based on the division, 3 divided by 8 is 0.375

This means that [tex]12 + \frac{3}{8} = 12 + 0.375 = 12.375[/tex]

Therefore 12.375 is your answer

Hope you understood and have a nice day!! :D

Step-by-step explanation:

Answer:

37317600  beats she will have in 4 years.

Step-by-step explanation:

Given that,

A typical person has an average heart rate of 71.0 beats/min.

We need to find the number of beats she have in 4 years.

As 1 year = 525600 min

1 min = 71 beats

525600 min = 525600 × 71

=37317600  beats

Hence, 37317600  beats she will have in 4 years.

Answer: I think that if it is not 214 than you should just guess and see if that is the correct answer

Step-by-step explanation:

Answer:

A. y=-4/3x

Step-by-step explanation:

The line that passes through those points has a slope of -4/3

Slope intercept form is y=mx+b

whereas m is the slope and b is where the line intercepts the y-axis.

the line intercepts the y-axis at the origin.

Substitute the slope into the equation

y=-4/3x+0

y=-4/3x

The question is incomplete. Here is the complete question.

USA Today reported that 36% of adult drivers admit that they often or sometimes talk on a cell phone when driving. This was based on a random sample of 1004 adult drivers.

a) What is a 90% confidence interval for the true proportion of adult drivers who have often or sometimes talk on a cell phone when driving?

b) What is a 95% confidence interval for the true proportion of adult drivers who have often or sometimes talk on a cell phone when driving?

c) What is a 99% confidence interval for the true proportion of adult drivers who have often or sometimes talk on a cell phone when driving?

d) What do you notice?

Answer and Step-by-step explanation: The way to calculate confidence interval for proportions is by using the following formula:

[tex]z(\sqrt{\frac{p(1-p)}{n} } )[/tex]

where

p is the sample population proportion

n is the number of individuals in the sample

z is z-score associated of the % of confidence

a) A 90% confidence has a z-score of z = 1.645

Calculating:

Interval = [tex]1.645(\sqrt{\frac{0.36(1-0.36)}{1004} } )[/tex]

Interval = [tex]1.645(\sqrt{0.00023} )[/tex]

Interval = [tex]1.645(0.01515)[/tex]

Interval = 0.025

A 90% Confidence interval for true population is between 0.335 and 0.385.

b) A 95% confidence has a z-score of z = 1.96

Since the sample parameter didn't change, the interval will be:

Interval = 1.96(0.01515)

Interval = 0.03

For a 95% confidence, interval is between 0.33 and 0.39.

c) A 99% confidence has a z-score of z = 2.58

Interval = 2.58(0.01515)

Interval = 0.39

For a 99% confidence, interval is between -0.03 and 0.75

d) Confidence interval tells you how certain your results from polling or survey would represent the real population's behaviour. In the experiment above, as the percentage of certainty grows, closer the real population proportion actually is for adult drivers who often or sometimes talk on a cell phone when driving.
