The second Graph

Step-by-step explanation:

The question is asking what graph is linear.

The first graph is of an absolute value function which is not linear.

The second is of a line. This is linear.

The third looks to be either an exponential or a logarithmic function. Both of which are not linear.

Jenny has 6 marshmallows in her hot chocolate and Julie has 0 marshmallows in her hot chocolate

From the question, we are to determine the number of marshmallows Jenny and Julie each have in their hot chocolate

From the given information,

"Jenny put 6 more marshmallows in her cup than Julie"

Then, we can write that

x - y = 6  ---------- (1)

Also,

"Together Jenny and Julie had a total of 6 marshmallows"

That is,

x + y = 6 ---------- (2)

Add equations (1) and (2) together

   x - y = 6

+ [x + y = 6

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

2x = 12

x = 12/2

x = 6

Substitute the value of x into equation (2)

x + y = 6

6 + y = 6

y = 6 - 6

y = 0

Hence, Jenny has 6 and Julie has 0

Length of diagonal WY is 13.03 units

What is Distance Formula?

Distance between two points is the length of the line segment that connects the two points in a plane.

The formula to find the distance between the two points is usually given by d=√((x2 – x1)² + (y2 – y1)²).

This formula is used to find the distance between any two points on a coordinate plane or x-y plane.

According to the given question:

WXYZ is a rectangle and diagonals of a rectangle are equal in length

Coordinates of W = (-4,5) and Y = (3,-6)

To find the length of diagonal WY, we need to find distance between points W and Y.

Using distance formula to find WY

= √((3 – (-4))² + (-6 – 5)²)

= √170

After 11.61 years the given principal amount of $ 900 will be double.

What is Compound interest?  

Compound interest is interest charged on a loan and is determined by both the principal amount and the rate of interest compounding per year.

The formula for the Amount when compound interest is calculated is given by

                  Amount, A = P(1+r/n)^nt  

P = Principal amount

r = Rate of interest

n = Number of compounds

t = Time period in years

Given:

Principal amount = $ 900

Rate of interest = 6% = 6/100 = 0.06

Number of compounds = 12    [ ∵ compounded monthly]

We need to find the time period

Assume that after 't' years the amount will be doubled

From the given data and formula,

Amount, A = 900(1+0.06/12)^12t        

                  = 900(1+0.06/12)^12t

                  = 900(1 + 0.005)^12t

                  = 900 (1.005)^12t  

As we assumed after 't' years the amount is double

=> 900 (1.005)^12t  = 2 × 900

=>         (1.005)^12t  = 2    

Applying log on both sides

=>  log (1.005)^12t  = log 2

=>    12t log(1.005) = log 2

=>                     12t = log 2/log(1.005)

=>                     12t = 0.30108/ 0.00216  

=>                     12t = 139.888

=>                         t =  11.61

Hence, after  11.61 years the given principal amount of $900 will be double.

Just go backwards. translations on a graph are pretty simple once you understand left vs right and up vs down.

The required translation to move the image back to the original position is 3 units right and 3 units down. Option A is correct.

Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.

The translation processes in geometry enable the shift of figures from one location to other.

Here,
The given translation is ,
a figure is translated 3 units left and 3 units up,
(x' , y') ⇒ (x - 3 , y + 3 )

To shift back the image,
x' = x - 3  ⇒ x = x' + 3
y' = y + 3 ⇒ y = y' -3

Thus, the required translation to move the image back to the original position is 3 units right and 3 units down. Option A is correct.

Based on the provided information, Jerry's Z score will be negative, while Corey's Z score will be positive.

A Z-score refers to a numerical measurement that defines the raw value's relationship to the mean of a group of values. It is measured in terms of standard deviations from the mean. If a Z-score is 0, it means that the data point's score is identical to the mean score. A negative z-score indicates that the data point is below average or mean and a positive z-score indicates that the data point is above average or mean. Consider the formula for z score which is given by:

z = (x - µ)/σ where x is the given data value, µ is the mean, and σ is the standard deviation.

Hence, if the x < µ, the z score will be negative while if x > µ, the z score will be positive. As Corey scored higher than the mean on his SAT, his z score will be positive, and Jerry scored lower than the mean on his SAT, his z score will be negative.

A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more numbers, or coordinates.

Here, we have

Triangle ABC is dilated by a factor of 2 with the center of dilation at the origin to form triangle A'B'C'.

A = ( 0,2)

B = (2, 0)

C = (4,4)

After applying dilated by a factor of 2, we get

A' = (0,4)

B' = (4,0)

C' =(8,8)

In 11.71 years the amount will double to the principal amount

The interest charged on a loan or deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal amount and Compounded interest. This is the major distinction between compound and simple interest is this.

The formula  used for

where P = Principal amount

r = Rate of interest in decimal

n = Number of compounds per year  

t = Time period  

Here from the given data,

Principal amount, p = $ 2500

Rate of interest, r = 6% = 6/100 = 0.06

Number of compounds, n = 2    [ ∵ 12/6 = 2 ]

Here we need to find the time period

Let's assume that after 'n' years the amount will be doubled i.e $ 5000

From the given problem,

Amount, A = 2500(1+0.06/2)²ⁿ        

= 2500(1+0.06/2)²ⁿ  

= 2500(1 + 0.03)²ⁿ  

= 2500 (1.03)²ⁿ    

As we assumed after 'n' years the amount is $ 5000

=>  2500 (1.03)²ⁿ   = 5000

=> (1.03)²ⁿ   = 2  

Apply to log on both sides

=> log (1.3)²ⁿ  = log 2

=> 2t log (1.3) = log 2

=> 2t = log 2/ log(1.03)

=> 2t = 0.301029996/(0.0128372247)

[ use calculator for log (1.03) and log 2]

=> 2t = 23.4497722

=> t = 11.7248861  

=> t = 11.71 ≅ 11 years

In 11.71 years the amount will double to the principal amount

The required probability for purchasing more than one costume is 0.03.

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lies in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

The given problem can be solved as follows,

The number of visitors purchasing no costume, exactly one and more than one costumes are given as 81, 6 and 3 respectively.

Then, the total number is 81 + 6 + 3 = 90

Now, the probability of purchasing more than one costume is given as,

P(More than one costume) = 3/90

                                            =  1/30

                                            = 0.03

Hence, probability that the next person will purchase more than one costume is 0.03.

We want to study the population formula of a given US state according to exponential equation.

a) 23.1 millions.

b) in 2013 - 2014

What is exponential equation?

The exponential function may be a function denoted by f(x)=\exp or e^. Unless otherwise fixed, the term usually refers to the positive-valued operate of a true variable

Main body:

The population state is:

A = 23.1*e^(0.0153*t)

In millions.

Where t represents the number of years after 2000.

a) For the population at the year 2000, we need to evaluate the function at t = 0 (2000 is 0 years after 2000).

A(0) = 23.1*e^(0.0153*0) = 23.1

The population at year 2000 was 23.1 millions.

b) Now we want to solve:

A(t) = 28.3 = 23.1*e^(0.0153*t)

        28.3/23.1 = e^(0.0153*t)

       1.23 = e^(0.0153*t)

Now we can apply the natural logarithm to both sides:

ln(1.23) = ln( e^(0.0153*t) )

ln(1.23) = 0.0153*t

ln(1.23)/0.0153 = t = 13.5

Hence, 13.5 years after 2000 the population will be 28.3 million.
