Step-by-step explanation:

The Z-score for a weekly rental is 2.45 which is the correct answer would be option (B).

A Z-score is defined as the fractional representation of data point to the mean using standard deviations.

Given the average cost to rent a car for a week is $276

And the standard deviation is $60

To determine the Z-score for a weekly rental of $423.00

Here,

ц = 276

σ = 60

X = 423

⇒ z-score = (X-ц )/σ

Substitute the values,

⇒ z-score =  (423 - 276)/60

⇒ z-score = 147/60

⇒ z-score = 2.45

Hence, the z-score for a weekly rental is 2.45.

Answer:

1 [tex]\frac{1}{2}[/tex] miles

Step-by-step explanation:

Convert 3 [tex]\frac{3}{4}[/tex] and 2 [tex]\frac{1}{2}[/tex] into improper fractions

Subtract them like a regualr equation

[tex]\frac{15}{4}[/tex] - [tex]\frac{9}{4}[/tex] = [tex]\frac{6}{4}[/tex]

Convert  [tex]\frac{6}{4}[/tex] into a mixed number to get 1 [tex]\frac{1}{2}[/tex]

Answer: b

Step-by-step explanation:

Cuz is a negative get in absolute value it always comes out positive

And it says below 0-9=-9

Answer:

Step-by-step explanation:

__________________________________________________________

B is the answer because,

if the negative sign is not inside the "brackets," then the number will still be negative.

__________________________________________________________

But, if the negative sign is connected to the number, or inside the "brackets," then it will always be positive.

__________________________________________________________

Here are the reasons why the rest are wrong.

__________________________________________________________

A is not correct because the outcome isn't negative, even though it's correct in mathematical instances.

__________________________________________________________

C is not correct because it is plainly not correct in itself.

__________________________________________________________

D is also not correct because it is not correct in the mathematical equations, even though it has a -9 as the equal, it's still wrong.

Answer:

The answer is "[tex]22,246 \ H_z \ \ and \ \ 7.3\%[/tex]"

Step-by-step explanation:

The sampling rate: [tex](f_s) = 52,500 \ \frac{samples}{sec}[/tex]

In point a:

The sample signal frequency = f  

They recognize that the id [tex]\geq[/tex] 2f sampling frequency could be returned to its original signal unless the aliase effect is detected elsewhere,  Yet under percentage =18%

[tex]\ sampling \ rate = 2 \times 1.18 \times f[/tex]

[tex]\to f = \frac{52,500}{2 \times 1.18}\\\\[/tex]

       [tex]= 22,246 \ h_z[/tex]

In point b:

Maximum 22,242 frequency is increased by [tex]10 \ \%[/tex]

[tex]f_a =22,246 \times 1.1[/tex]

    [tex]= 24,470.6\\\\=24,471[/tex]

[tex]\ sampling \ rate= x \times 2 \times 24,2471 \\[/tex]

                    [tex]x= \frac{52,500}{48,942} \\\\x= 1.073\\\\[/tex]

over sampling percentage [tex]= 7.3 \ \%[/tex]

Maya mistake is in step 1

Step-by-step explanation:

Answer:

Maya in Step 1

David in Step 3

Step-by-step explanation:

Maya

5 (x-3) = 12

5x - 15 =12 (step 1)

David

3x + 3 = 2 (x - 1)

3x + 3 = 2x - 2

3x - 2x + 3 = 2x - 2x - 2

x + 3 = -2  (step 3)
