Mean = 12000
Standard Deviation = 2000
We have to find how many standard deviations is 14,500 away from the mean.
This can be achieved by calculating the z-score
Z-score tells us how many standard deviations above or below is a sample value from the mean. A positive z value shows, sample value is above the mean.
z score can be calculated as = (Sample Value - Mean )/Standard Deviation)
So,
Z-score =
This means, 14,500 is 1.25 standard deviations above the mean value 12,000.
Part A: 5 is the coefficient, w is the variable, 50 is the constant
Part B: 10 x 5 = 50 + 2 x 20 = 40+ 50 = $140
Part C: the constant,50,would change and become 85. Hope this helps :)
Hi there!
First we need to realise that the 18% discount equals John's savings. Therefore 18% of the original price is $13.23.
When we know 18% of the price, we can also find 1% of the total price.
18% = $13.23
Divide both sides by 18.
1% = $0.735
To find the total price, which equals 100%, we know only need to multiply both sides by 100.
100% = $73.50.
Therefore, the original price for the coat is $73.50.
~ Hope this helps you!
The answer 456 fe
Because it the benefit is doing today
The answer is zero because the the discriminant is negative
