Lamont should sample only registered voters to predict who will be elected mayor

A survey is a research method used for collecting data from a predefined group of respondents to gain information and insights into various topics

Since Lamont is trying to predict who will be elected, surveying people that are not registered to vote will not give him an accurate prediction.  If someone is not registered to vote, they cannot vote for any candidate.

To get more accurate results, Lamont should only sample people that are registered voters.

Answer:

2.27

Step-by-step explanation:

Let's start the sum as follows:

x³ = 8

X × X × X = 8

This means there are 3 number which after Multiplication gives answer 8.

If 2 is multtiplied 3 times it will give you 8

Thus the answer of x is 2

x = 2.

x^3 = -8

The cube root of 8 is 2 = 2 x 2 x 2 is 8.

But, the answer is negative, which means that the cube root of -8 must be -2.

-2 x -2 x -2 = -8

x = -2

The length of the side labeled x is Option B.  [tex]\sqrt{21}[/tex].

Pythagorean theorem is a basic principle to be applied when determining the unknown side of a given right triangle when the values of two sides are given. The theorem states that;

/Hyp/^2 = /Adj/^2 + /Opp/^2

From the triangle given, we have;

/Hyp/^2 = /Adj/^2 + /Opp/^2

x^2 = 4^2 + ((5)^1/2)^2

      = 16 + 5

      = 21

x = 21^1/2

Given:

Angle 6 = 25 degrees

To Find:

The value of Angle 7

Solution:

We know that,

the value of Angle 6 is equal to 25 Degrees

Since Angle 6 and Angle 7 together comprise of a Straight Line, this means that they are Supplementary Angles.

Therefore,

Angle 6 + Angle 7 = 180 degrees

This implies that,

25 degrees + Angle 7 = 180 degrees.     (since Angle 6 = 25 Degrees)  

Angle 7 = (180-25) degrees

Thus ,

Angle 7 = 155 degrees

Hence, Angle 7 is  155 degrees (Option 1)

Answer:

$16.77

Step-by-step explanation:

1. Grapefruit cost 1/2 pound = 0.5 pound

2. Since the bag weighs 6.5 pounds, you can do 6.5/0.5 to find the number of grapefruits

3. 6.5/0.5 = 13

4. The total cost of the grapefruits would be $1.29 * 13 = $16.77

Answer:

{x | x ≠ -1, 2, 4}

Step-by-step explanation:

Domain: input values (x-values)

Asymptote: a line which the curve gets infinitely close to, but never touches.

Hole: a point on the graph where the function is not defined.

From inspection of the graph:

As vertical asymptotes and holes restrict the domain of a rational function, the domain is  {x | x ≠ -1, 2, 4}

Answer:

The student would need to save $9.17 more per month

Step-by-step explanation:

350 = 12(x+20)

350 = 12x + 240

12x = 110

x = 110/12

x = $9.17

Answer:

10.9 units

Step-by-step explanation:

Let the hight of the wall be " x ".

( Height = x )

Here,

12 foot ladder is the hypotenuse side.

( Hypotenuse = 12 )

5 feet away is the base side.

( Base = 5 )

Formula : -

Height² + Base² = Hypotenuse²

x² + 5² = 12²

x² + 25 = 144

x² = 144 - 25

x² = 119

x = √119

x = 10.9 approximately

Therefore,

High up the wall does the top of the ladder reach is 10.9 units.

Answer:

9 days

Step-by-step explanation:

because if you turn 7 ⅞ into 63/8 then do 63÷7 you get 9

Answer:

9 days.

write 7/8x9, and put a 1 under it.

7x9=63

8x1=8

63/8 simplified is 7 7/8

Step-by-step explanation:

Answer:

Statement 1 - false

A function is one-to-one or many-to-one.

One-to-one means each value in the range (y-values) corresponds to exactly one value in the domain (x-values)

Many-to-one means some values in the range (y-values) correspond to more than one (many) value in the domain (x-values).

Therefore, as some y-values correspond to more than one x-value, this is a many-to-one function.

The true statement should be:

The relation is a function because some y-values correspond to more than one x-value.

Statement 2- true

The domain is the set of input values (x-values).  Therefore, the domain is 3 ≤ x ≤ 8 as the smallest x-value is 3 and the highest x-value is 8.

Statement 3 - true

The range is the set of output values (y-values).  Therefore, the range is {6, 7, 8, 10} as these are the y-values of the ordered pairs.

Answer:

The mode would not increase or decrease.

Step-by-step explanation:

I say this because the mode is the value(s) in the data set that occur most frequently. 30 is the mode before adding 80 because 30 is in the set 3 times, more than the other values. Because 80 would be the only 80 in the set it would not become the mode once added. I hope this explained my reasoning and helped!
