Which function best represents this graph?

Answer:

Step-by-step explanation:

a) 16^ (-1/4)=2^4(-1/4)=2^-1=1/2

b) 27*9^3x=

we write 27=3^3

9=3^2*3x=3^6x

3^3 x 3^6x=   k=3+6x

The scenario represented by the linear function y = x + 2 is given by:

Valerie has $2 and then earns $1 per week (where x is the number of weeks) in allowance, for a total of y dollars.

A linear function is modeled by:

y = mx + b

In which:

For this problem, we have that:

Thus the function is given by:

y = x + 2.

Which means that the initial amount is of $2, and increases by $1 for each unit of time, hence the correct option is:

Valerie has $2 and then earns $1 per week (where x is the number of weeks) in allowance, for a total of y dollars.

Answer: D. This was a random sample. It may have included anyone in attendance.

Step-by-step explanation:

The options are:

A. This was a biased sample. Jim should interview all in attendance.

B. This was a census. Any guest may have participated.

C. This was a random sample. It may not have included anyone in attendance.

D. This was a random sample. It may have included anyone in attendance.

A random sampling is simply referred to as a subset of individuals that are picked from a larger set of individuals.

With regards to the question, Jim wanted to find out what the audience thought about the debate and after the event, he stood at the exit to survey every fifth guest.

This means that it was a random sampling and anyone could have been picked, the sampling wasn't bias.

Answer:

x= 12

Step-by-step explanation:

Answer:

182.58842

Step-by-step explanation:

Given that:

Sample size (n) = 171

Population standard deviation σ = 11

Sample standard deviation s = 11.4

males is more than 11 bpm. For a random sample of 171 adult males, the pulse rates have a standard deviation of 11.4 bpm find the value of the statistic

The test statistic :

X² = ((n - 1) / σ²) * s²

X² = ((171 - 1) / 11²) * 11.4²

X² = ((170) / 121) * 129.96

X² = 1.4049586 * 129.96

X² = 182.58842

Answer:

the value of the dimes

Step-by-step explanation:

The expression 0.10y most likely represents the number of dollars when all dimes are clubbed together.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Amy has a collection of dimes and quarters. If the expression is given as,

V = 0.25x + 0.10y represents the total value of the coins Amy has.

The expression 0.10y most likely represents the number of dollars when all dimes are clubbed together.

Answer:

43$

Step-by-step explanation: Three tickets total.

2 tickets cost 13$    =26

1 ticket 17 = 43 total

Hope this helped! God Bless!!

The total cost of the tickets for William’s family with 1 adult and 2 children is $43.

William's age = 11 years

Price for an adult = $17

Price for a child = $13

The total number of tickets to be bought will be 3 i.e. William, His Granddad, and William's younger brother i.e. 1 adult ticket and 2 children tickets.

Total price = price of 1 adult ticket + price for 2 children's ticket

Total price =17+2*13

Total price =17+26

Total price =$43

Therefore, the total cost of the tickets for William’s family is $43.

Answer:

Use the two ordered pairs to find the slope, m.

Then substitute one set of ordered pairs and m into y = mx + b to solve for b

Step-by-step explanation:

If we are given two ordered pairs of a function and we need to write an equation that represents the linear function, first, what we need to do is to use the two ordered pair to find the slope, m, using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex].

After getting the slope (m), find the value of the y-intercept (b), by substituting the value of one of the ordered pairs and the slope value (m) into y = mx + b.

Once the value of m and b is known, plug in the value of m and b into y = mx + b to derive the equation of the linear function.

Use the 2 ordered pairs to find the slope, m .

Then substitute m and one set of ordered pairs into y = mx + b to solve for b.

If given the 2 ordered pairs for a function, the ordered pairs can be first used to find the slope of the function.

For example

(x₁, y₁)(x₂, y₂)

m = slope = y₂ - y₁ / x₂ - x₁

The slope(m) is then substituted in the slope intercept form equation.

y = mx + b

where

m = slope

b = y-intercept

And one set of the ordered pairs is also substituted in the equation to get the value of the y-intercept(b).

Step-by-step explanation:

For us to have an infinite number of solutions, then, what we have on the right hand side will be exactly what we have on the left hand side

Since we have -6x + 6 on the left hand side

To have infinite number of solutions, what we have on the right hand side will be the same

Thus, we have -6x + 6 on the second side

Step-by-step explanation:

Coz, the way you identify a perpendicular line is by looking for its negative reciprocal. The neagtive reciprocal of 5= 1/5

Now, to check the ans we can multiply the negative reciprocal by "m"

(m in y=mx+c or y=mx+b)

in this case the "m" is stated as 5, so all we need to do is  1/5*5 if the ans is 1 then your ans is right....and over here it is

So thats how you identify & check perpendicular lines!
