Step-by-step explanation:

Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years. *

The formula for Depreciation rate =

y = a(1 - r) ^t

Where

y = Value of the car after t years

a = Initial value of the car = $23,000

t= time in years = 4 years

r = Depreciation rate = 12% = 0.12)

y = $23000 (1 - 0.12)⁴

y = $13792.99328

Approximately = $13,793:

ycow [4]

Answer:

The price of a package of chocolate chip is $13.25

The price of a package of gingerbread is $17.18

Step-by-step explanation:

11x + 12y = 352

10x +8y = 270

Let "x" be the price of a package of chocolate chip.

Let "y" be the price of a package of gingerbread.

11x + 12y = 352(Multiply the 1st row by 10)

10x +8y = 270 (Multiply the 2nd row by 11)

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

110x + 120y = 3520

110x +88y = 2970

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

3y = 550

y =550/3

y = 17.1875

The price of a package of gingerbread "y" is $17.18

Let's pick the first equation "110x + 120y = 3520"

110x + 120y = 3520

110x+ 120(17.1875)= 3520

110x+2062.5=3520

110x=3520−2062.5

110x=1457.5

x= 1457.5/110

x=13.25

The price of a package of chocolate chip is $13.25

A) 0.2076
B) 0.6786
C) 0.3214

Explanation:
A) $P(X=5)=_8C_5(0.75)^5 \times(1-0.75)^{8-5}
\\
\\=_8C_5(0.75)^5 \times (0.25)^3=0.2076$
B) We find the probability that X=6, 7, or 8:
$P(X=6)=_8C_6(0.75)^6(0.25)^2=0.3115
\\
\\P(X=7)=_8C_7(0.75)^7(0.25)^1=0.267
\\
\\P(X=8)=_8C_8(0.75)^8(0.25)^0=0.1001
\\
\\0.3115+0.267+0.1001=0.6786$
C) P(X≤5) = 1-P(X>5) = 1-0.6786 = 0.3214
