Answer:

If a set of points is a function, the elements of the set must have the same number of elements.

For example, if the function is from A→B, the elements must be ordered pairs.

So Y is not a function.

---------------------------------------------------------------------------------------------

If Y is in fact  {(2, 6), (3, 1), (4, 1), (5, 6)}

then Y is a function, because each of the first coordinates appears only once.

In functional notation, we have f(2)=6, f(3)=1 etc....

remark: if a first coordinate is repeated, for example if we have (2, 6) and also (2, 8)

this would mean f(2)=6, but also f(2)=8, which means f is not a function.

Answer:

18.38 B

Step-by-step explanation:

let x be the cost of 3.5 pounds

5.25/1 = x/3.5

5.25=x/3.5

18.375=x

since you can't buy 3.5 pounds with 18.37 (1 penny short), you need 18.28

Answer:

The  estimate the proportion of college students who drive cars with manual transmissions with 90% confidence is  

      [tex]0.171 <  p <  0.297 [/tex]  

Step-by-step explanation:

From the question we are told that

    The sample size is  n  =  124

    The population proportion p =  0.06

     The number of cars with manual transmissions is  k =  29

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 the sample proportion is mathematically represented as

       [tex]\^ p = \frac{ 29 }{124 }[/tex]

=>   [tex]\^ p = 0.234[/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} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]

=>   [tex]E =   1.645  * \sqrt{\frac{0.234 (1- 0.234 )}{124} } [/tex]

=>   [tex]E =  0.063  [/tex]

Generally 95% confidence interval is mathematically represented as  

      [tex]\^ p -E <  p <  \^ p +E[/tex]

=>  [tex]0.234  - 0.063  <  p <  0.234  + 0.063 [/tex]

=>  [tex]0.171 <  p <  0.297 [/tex]  

Answer:

960

Step-by-step explanation:

If there are 120 calories in 3/4 or 0.75 cup

In one cup = 120/0.75

= 160 calories per cup

160 * 6 cups = 960 calories in 6 cups

Answer:

25%

Step-by-step explanation:

Initial no of students = 16,000

Final no of students = 20,000

We need to find the percent increase in enrollment.

The increase in no of students = 20,000 - 16,000

= 4000

Percentage = (increase/initial no of students) × 100

[tex]\%=\dfrac{4000}{16000}\times 100\\\\=25\%[/tex]

Hence, the percent increase is 25%.

Step-by-step explanation:

Answer:

8 and -7

Step-by-step explanation:

Note that multiplication is commutative, in simpler terms, the order of multiplication doesn't matter at all. We shall use this to solve the problem.

[tex](-4)\times(-3\frac{5}{6} )= (-4)\times(-3)\times(\frac{5}{6})[/tex]

Now, what we also know is that a negative number times a negative number is a positive number. And we also know that 4 times 3 is 12.

So,

Writing the same thing in a more convenient way:

[tex]12\times\frac{5}{6} = 12\frac{5}{6}[/tex]

So the answer is the second alternative

Answer:

The cost of 2 quintal of rice is $10,000.

Step-by-step explanation:

To determine the cost of 2 quintals of rice, knowing that 90 kilos of said product is worth $ 4,500, it is first necessary to establish the equivalence between quintals and kilograms. In this regard, a quintal is equivalent to 100 kilograms, so 2 quintals are equivalent to 200 kilos.

Now, to determine the cost per kilogram of rice, the following calculation is required:

4,500 / 90 = X

50 = X

Therefore, 1 kilogram of rice costs $ 50. Thus, since 200 x 50 equals 10,000, 2 quintals of rice will cost $ 10,000.

Answer:

2nd option is the correct answer

Step-by-step explanation:

[tex]m \angle 1 > m \angle 3 \: \& \: m \angle 1 > m \angle 7 \\ [/tex]

According to the Exterior Angle Theorem, the true statement should be considered as the option b.

The exterior angle theorem defined that at the time when a triangle's side should be extended, the resultant exterior angle formed should be equivalent to the sum of the measures of the two opposite interior angles of the triangle.

So based on this, we can say that the option b is correct.

Answer:

1.08 is the constant of proportionality.

Step-by-step explanation:

The constant value (often written k) relating amounts that rise or fall uniformly together.

It is the ratio of the amounts y and x:

k = y/x

Put another way: y = kx

Example: you are paid $20 an hour

The constant of proportionality is 20 because: Pay = 20 × Hours worked
