PLZZZ HELP ME!!!!! Complete the table for the function f(x) = 2x - 3

Mathematics
1 answer:
Lana71 [14]3 years ago
4 0

Answer:


Step-by-step explanation:

f(x) = 2x - 3

f(-2) = 2(-2) -3 = -4 - 3 = -7

f(-1) = 2(-1) -3 = -2 - 3 = - 5

f(0) = 2(0) -3 = 0 - 3 = -3

f(1) = 2(1) -3 = 2 - 3 = -1

f(2) = 2(2) -3 = 4 - 3 = 1

f(3) = 2(3) -3 = 6 - 3 = 3

A certain city with population of 132,000 is to be divided into 11 voting districts, and no district is to have a population tha
galben [10]

Answer: Therefore, Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Number of population = 132000

Number of voting districts = 11

According to question,  no district is to have a population that is more than 10 percent greater than the population of any other district.

Let the number of population that the least populated district could have be 'x'.

So, it becomes,

x+10(1.1x)=132000\\\\x+11x=13200\\\\12x=132000\\\\x=\dfrac{132000}{12}\\\\x=11000

Hence, there are 11000 population that the least populated district could have.

Therefore, Option 'D' is correct.

A data set includes 103 body temperatures of healthy adult humans having a mean of 98.3degreesF and a standard deviation of 0.73
faust18 [17]

Answer:

CI = (98.11 , 98.49)

The value of 98.6°F suggests that this is significantly higher

Step-by-step explanation:

Data provided in the question:

sample size, n = 103

Mean temperature, μ = 98.3

°

Standard deviation, σ = 0.73

Degrees of freedom, df = n - 1 = 102

Now,

For Confidence level of 99%, and df = 102, the t-value = 2.62      [from the standard t table]

Therefore,

CI = (Mean - \frac{t\times\sigma}{\sqrt{n}},Mean + \frac{t\times\sigma}{\sqrt{n}})

Thus,

Lower limit of CI =  (Mean - \frac{t\times\sigma}{\sqrt{n}})

or

Lower limit of CI =  (98.3 - \frac{2.62\times0.73}{\sqrt{103}})

or

Lower limit of CI = 98.11

and,

Upper limit of CI =  (Mean + \frac{t\times\sigma}{\sqrt{n}})

or

Upper limit of CI =  (98.3 + \frac{2.62\times0.73}{\sqrt{103}})

or

Upper limit of CI = 98.49

Hence,

CI = (98.11 , 98.49)

The value of 98.6°F suggests that this is significantly higher and  the mean temperature could very possibly be 98.6°F

Three times the sum of a number and six<br> 3(x=6)<br> 3(x-6)<br> 3(x+6)<br> 3x+6
Stels [109]

Answer:

3(x+6)

Step-by-step explanation:

Parenthesis after a number typically means multiply, so 3 times the sum of an unspecified number (x), plus 6 would be 3 (x+6)
