Answer:
a. The sum of the first 100 odd positive integers - Not a statement
b. Everybody needs somebody sometime - Atomic statement
c. The Broncos will win the Super Bowl or I'll eat my hat - Molecular statement (disjunction)
d. We can have donuts for dinner, but only if it rains - Molecular statement (conditional)
e. Every natural number greater than 1 is either prime or composite - Atomic statement
f. This sentence is false - Not a statement
Step-by-step explanation:
A statement in mathematics can be said to be any declarative statement that can either be true or false. While a sentence is considered to not be a statement if
Statements are divided into 2:
Atomic statements: These are statements that cannot be split into mini statements.Molecular statements: These are the opposites of atomic statements. They are statements that cannot be spilt. This can further be divided into; conjunction, disjunction, conditional, bi-conditional and negationMia is a songwriter who collects royalties on her songs whenever they are played in a commercial or a movie.

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
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.

A room 24'-0" x 22'-6" requires ____ square feet of ceiling tile and ____ square yards of carpet. (1 square yard = 9 square feet; 3' x 3' = 9')
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
X + 10y - 4y + 4x

a m=undintified
b m= 0
c m= 11 over 4
d m= negative 11 over 4
Answer:
B

The physical plant at the main campus of a large state university receives daily requests to replace florescent light bulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 37 and a standard deviation of 8. Using the empirical (68-95-99.7) rule, what is the approximate percentage of light bulb replacement requests numbering between 37 and 61
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%
For the given pair of equations, give the slopes of the lines, and then determine whether the two lines are parallel, perpendicular, or neither.
10x – 3y = 3
3x + 10y = 30
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The slope of 10x - 3y = 3 is
(Type an integer or a simplified fraction.)
O B. The slope of 10x - 3y = 3 is undefined.
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

Michelle is an architect who builds skyscrapers. She has a sheet of measurements that she needs convert before she can begin her next project. One wall is 12 ⅜ ft long and has a width of 19.73 ft. Change the given mixed number to a decimal. Circle the correct response.
A 12.3 ft
B 12.375 ft
C 12.38 ft
D 12.83 ft
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

The question is on the jpg link.
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

A typical person has an average heart rate of 71.0 beats/min. Calculate the given questions. How many beats does she have in 4.0 years
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.
