On an exam with μ = 52, you have a score of X = 56. Which of the following values for the standard deviation would give you the

Aleonysh [2.5K]

Answer:

σ = 2 (option a)

Step-by-step explanation:

You would want the smallest standard deviation possible.

Think of it like this: if everyone, other than you, got only 50, 51, 52, 53 then you would be the ultimate highest position in the class.

As opposed to being an average position if the scores were about 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60 ---your score would not put you in the highest position in the class distribution.

So, a standard deviation of σ = 2 would give you the highest position in the class distribution.

A new car is purchased for 23900 dollars. The value of the car depreciates at 9.75% per year. To the nearest year, how long will

inna [77]

Answer:

11 years

Step-by-step explanation:

we know that

The formula to calculate the depreciated value is equal to

$V=P(1-r)^{x}$

where

V is the depreciated value

P is the original value

r is the rate of depreciation in decimal

x is Number of Time Periods

in this problem we have

$P=\$23,900\\r=9.75\%=0.0975\\x=?\\V=\$7,700$

substitute in the formula

$7,700=23,900(1-0.0975)^{x}$

$(77/239)=(0.9025)^{x}$

Apply log both sides

$log(77/239)=xlog(0.9025)$

$x=log(77/239)/log(0.9025)$

$x=11\ years$

Plz help ASAP I can't figure out

NeTakaya

Answer:

x = ±√17

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side of the equation, you do to the other.

Also note that the x has a power of 2. To isolate the x, simply root both sides of the equation.

x² = 17 ; √x² = √17 ; x = ±√17
