Answer:

The population is 34,000. The sample is 2,000

Step-by-step explanation:

Population in statistics can be explained as the group or set of all elements which are of particular interest to a researcher or a study. In the scenario above, the research interest concerns customers who pay with a debit card, whose number amounts to 34,000, this value refers to the population. The sample is referred to as the subset of the population or larger sample, the sample from the study corresponds to number of debit card users who were selected at random to participate in the survey. This value is 2000.

Answer:

The common factor is 1.

Step-by-step explanation

The common factor of 1 and 2 is 1 since 1x2=1.

Answer:

see explanation

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = [tex]\frac{1}{2}[/tex] x + 4 ( multiply through by 2 to clear the fraction )

2y = x + 8 ( subtract 8 from both sides )

2y - 8 = x

Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then

[tex]f^{-1}[/tex](x ) = 2x - 8

[tex]f^{-1}[/tex](4) = 2(4) - 8 = 8 - 8 = 0

Answer:

y = -2x - 3

Step-by-step explanation:

A standard equation written in slope-intercept form looks like this:

y = mx + b

m is the slope and b is the y-intercept.

First let's identify the y-intercept.

This is the point where the line crosses the y-axis. That point is (0, -3); therefore, our y-intercept is -3.

y = mx - 3

Now let's find the slope.

This is the rate of change of the line. It is represented by rise over run. "Over" means the number will be presented as a fraction.

We can see that from Point 2 (on the right), we rise 2 units to the level of Point 1 (on the left). This is expressed as 2.

To get directly to Point 1, we run backwards 1 unit. This is expressed as -1.

rise: 2

run: -1

rise/run = 2/-1 = -2

-2 is our slope.

y = -2x - 3

This is your equation.

Hope this helps!

Answer:

280.8 pounds

Step-by-step explanation:

Original weight of pig = 54 pounds

Percentage increase in weight = 420%

Current weight of pig = original weight + 420% of original weight

= 54 + 420% of 54

= 54 + 420/100 * 54

= 54 + 4.2 * 54

= 54 + 226.8

= 280.8 pounds

Current weight of pig = 280.8 pounds

HAVE A NICE DAY

Answer:

B

Step-by-step explanation:

; factor the left side of the equation

; (x−3) (x+5) = 0

set factors equal to 0

x − 3 = 0

or

x + 5 = 0

; so, x = 3  or  x = −5

Answer:

32 degrees.

Step-by-step explanation:

A triangle is 180 degrees.

180 - 85 - 63 = 32 degrees.

Answer:

x = 32

Step-by-step explanation:

All interior angles in a triangle equal to 180

use this to solve for x

180 = 85 + 63 + x

180 - 85 - 63 = x

32 = x

Answer:

60˚, 75˚

Step-by-step explanation:

for part a:

since all sides are the same length (represented by the 3 same type of tick marks on all sides) then the triangle is equilaterial. Which means all the angles are the same.

Sum of angles in a triangle is 180˚.

x represents the value of <N, <M, and <P

so since all angles are the same, 3x = 180, all angles of part a triangle are 60˚. Therefore, <M is 60˚.

for part b:

this is an isoceles triangle since two sides are the same length.

If it's isoceles, that means it's 2 base angles are the same value.

We've already been given the vertex angle.

x represents the value of <S and <Q

2x + 30 = 180.

2x = 150

x = 75˚

The Thales theorem states that: If three points A, B, and C lie on the circumference of a circle, whereby the line AC is the diameter of the circle, then the angle ∠ABC is a right angle (90°).

Answer:

7

Step-by-step explanation:

7.11 × 10^7

The number 71,100,000 can be written in scientific notation as 7.11×10⁷ after using the concept of the scientific form of a number.

A number is a mathematical entity that can be used to count, measure, or name things. For an example, 1, 2, 56 etc. are the numbers.

It is given that:

The number is 71,100,000

After converting it into the scientific notation:

7.11×10⁷

Which is equal to 71,100,000

Thus, the number 71,100,000 can be written in scientific notation as 7.11×10⁷ after using the concept of the scientific form of a number.

#SPJ2

Answer:

22.09

Step-by-step explanation:

Given the expression ln(x-2)^2=6

Take exponent of both sides

e^ln(x-2)^2=e^6

(x-2)² = e^6

(x-2)² = 403.43

x - 2 = √403.43

x - 2= 20.09

x = 20.09 + 2

x = 22.09

Hence the value of x is 22.09

Answer:

72 yd³

Step-by-step explanation:

Answer:

13, 14

Step-by-step explanation:

The parameters of the numbers are;

A whole number value = 2 × Another number + 6

The sum of the two numbers is less than 50

Given that the first number is equal to more than twice the second number, we have that the first number is the larger number, while the second number is the smaller number

Where 'x' represents the second number, we get;

x + 2·x + 6 < 50

Simplifying gives;

3·x + 6 < 50

x < (50 - 6)/3 = 14.[tex]\overline 6[/tex]

x < 14.[tex]\overline 6[/tex]

Therefore, the numbers for which the inequality holds true are numbers less than 14.[tex]\overline 6[/tex]. From the given option, the numbers are 13, and 14.

Answer:

x = 7

Step-by-step explanation:

The larger triangle is twice as big as the smaller triangle. Therefore, the length of the side EF is twice as large as the side YZ.

I multiplied 4.5 (the length of YZ) and 2 to get 9. The value of side EF is 3x-12 and should be equivalent to 9.

3x - 12 = 9

I solved this equation by adding 12 to both sides and dividing 3 on both sides.

The value of x is 7.

======================================================

Explanation:

The numbers up top are 1,1,1. They multiply to 1*1*1 = 1. So that means 1 is the numerator of the answer.

The numbers down below are 6,2,3. They multiply to 6*2*3 = 36. This is in the denominator for the answer.

That means (1/6)*(1/2)*(1/3) = 1/36

The rule I used is (a/b)*(c/d) = (a*c)/(b*d)
