the sum of four consecutive odd numbers is 48?
Answers
Answer:
The numbers are 9 + 11 + 13 + 15.
Step-by-step explanation: The equation for this is simple.
Take x as the smallest number of the 4 numbers. The second number would be x +2, third number is x+4, and the fourth number is x+6. you add these together, and you get: 4x +12 = 48, you then solve this as a linear equation. 48-12 = 36. Then you divide by 4, which gives you 9 as the smallest number of the 4 numbers. Remember that the second number is 9+2=11, third is 9+4=13, and the fourth is 9+6=15. If you add these together you get 9+11+13+15=48.

Sam is framing a closet under a stairway. The stairway is 20 ft 6 in. long, and its angle of elevation is 31º. Find the depth of the closet to the nearest inch.
Answers
Answer:
The depth is 127 inches.
Step-by-step explanation:
The stairway and its depth can be compared to a right angled triangle. Let the depth be represented by d.
But,
12 inches = 1 foot
20 ft 6 in = 20 + [tex](\frac{6}{12} )[/tex]
= 20.5 feet
So that applying the appropriate trigonometric function, we have;
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
Sin 31º = [tex]\frac{d}{20.5}[/tex]
d = 20.5 x Sin 31º
= 20.5 x 0.5150
d = 10.5575
d ≅ 11 feet
Therefore,
d = 10.5575 feet = (10.5575 x 12) inches
= 126.69 inches
The depth is 127 inches.

To estimate the average education level, in years, of residents in a certain county, a marketing team draws a random sample of 100 residents. Their education level averages to about 12.5 years; the standard deviation is about 2.8 years. The team estimates the average education level of all the residents of that county to be 12.5 years with what margin of error, for approximately 90% confidence?
Answers
Answer:
The margin of error is [tex]E = 0.4606 [/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 100
The sample mean is [tex]\= x = 12.5 \ years[/tex]
The standard deviation is [tex]\sigma = 2.8 \ years[/tex]
From the question we are told the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 90 ) \%[/tex]
=> [tex]\alpha = 0.10[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.645[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E =1.645* \frac{ 2.8 }{\sqrt{100} }[/tex]
=> [tex]E = 0.4606 [/tex]

A coin is tossed three times. Use this information to solve these problems.1) List the sample space.2) Find the probability of tossing heads exactly twice.3) Find the probability of tossing tails at least twice.
Answers
Answer:
1) sample space = {HHH, HHT, HTH, THH, THT, TTH, HTT, TTT}
2) pr(tossing heads exactly twice) = [tex]\frac{3}{8}[/tex]
3) pr(tossing tails at least twice) = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
In tossing a coin three times, the sample space is the possible outcomes for the number of toss.
So that for the question,
1) The sample space = {HHH, HHT, HTH, THH, THT, TTH, HTT, TTT}
The total number of possible outcome is 8.
2) pr(tossing heads exactly twice) = [tex]\frac{numner of outcome with exactly two heads}{total number of outcome}[/tex]
= [tex]\frac{3}{8}[/tex]
3) pr(tossing tails at least twice) = [tex]\frac{number of outcome with at least two tails}{total number of outcome}[/tex]
= [tex]\frac{4}{8}[/tex]
= [tex]\frac{1}{2}[/tex]

heidi subtract 9 from 17. first she adds to get 10.then she added again to find her answer is heidi correct Heidi is not correct to add blank then you add blank more to get 10 to 17 the answer is
Answers
Answer:
Heidi wants to compute:
17 - 9.
First, she adds to get 10, (we want to subtract 10, this is easier than subtracting 9) then she can do:
17 - 9 + 0
adding zero does not change the sum
1 - 1 = 0
then:
17 - 9 + 0 = 17 - 9 + 1 - 1
Now we can do:
17 - 9 - 1 + 1
17 - (9 + 1) + 1
17 - 10 + 1
(17 - 10) + 1
7 + 1 = 8
Then, first she needs to add -1, in order to subtract 10, and then she must add 1. As we added a number and its inverse, in total we added zero, so the sum did not change, but was easier to compute.

Answers
Answer:

Step-by-step explanation:
An Arithmetic Combination states that two functions f and g at any x i.e in the domain of both f and g, with one exception.
The quotient is not defined at values of x, where g is equal to 0 or we can say that both the functions must be defined at a point for the combination to be defined.
Given: f(x) = 3-2x and g(x) =
Then, using arithmetic combination of function definition:
......[1]
Now, first find the value of f(9) and g(8) ;
f(8) =3-2(8) = 3-16 = -13 and
Substitute these in equation [1] ;
Therefore, the value of (f/g)(8) is; -169
