A. Box Plot 2 is very consistent and the datas are tight. Box Plot 2 is more spread and opened.

B. Box Plot 1 has an outlier that makes the range of upper 25% of the data larger.

D. Box Plot 2 is 75% the size Box Plot 1’s sections. Since the shape of Box Plot 1 is tighter, this means that Box Plot 2 have a lower deviation in the data numbers.

The annual rate of depreciation, x, on a car that was purchased for $9,000 and is worth $4,500 after 5 years can be found using

Zolol [24]

Answer:

Step-by-step explanation:

We know that exponential formula of depreciation

$A=P(1-x)^t$

where

P is the initial amount

x is the interest rate

A is the amount after t years

we are given

The annual rate of depreciation, x, on a car that was purchased for $9,000

so, P=9000

we can plug value it

$A=9000(1-x)^t$

we are given

when x=5 , A=4500

so, we can plug it and solve for x

$4500=9000(1-x)^5$

$\frac{9000\left(1-x\right)^5}{9000}=\frac{4500}{9000}$

$\left(1-x\right)^5=\frac{1}{2}$

$x=-\left(\frac{1}{2}\right)^{\frac{1}{5}}+1$

$x=0.12945$

so, interest rate is 13%

now, we can plug x

and we get

$A=9000(1-0.13)^t$

$A=9000(87)^t$

Answer:

Square root of 87.35 will be plotted between 9 and 10 as shown below.

Step-by-step explanation:

We are given that, 'The number line is numbered in tenths'

Also, the square root of 87.35 is given by,

$\sqrt{87.35}=9.4$

That is, we have to plot the point 9.4 on the number line numbered in tenths.

As, 9.4 will lie between the points 9 and 10.

Thus, we get that square root of 87.35 will be plotted between 9 and 10 as shown below.

Please help me. math.

KiRa [710]

Answer:

y =293(1.06) ^x

y = 370 after 4 years

Step-by-step explanation:

If we are using the model for growth

y = a ( 1+b)^x

a is the initial population

b is the increase rate

We can substitute the values into the equation

y =293 (1+.06) ^ x

y =293(1.06) ^x

Let x equal 4 for the 4 years

y = 293(1.06)^4

y=369.9
