if a normal distribution has a mean of 132 and a standard deviation of 20 what is the value that has a z score of 1.8?

klasskru [66]

Answer:

168 = x

Step-by-step explanation:

mean = u=132

standard deviation =sigma = 20

z score =z=1.8

The formula is

z = (x-u)/ sigma

Substituting what we know

1.8 = (x-132)/20

Multiply by 20

1.8*20 = (x-132)/20 *20

36 = x-132

Add 132 to each side

36+132 = x-132+132

168 = x

SI on rs 5000 at 10percent for a certain period is rs 500 less then the interest on rs 6000 at 10 percent p.A for the same perio

svet-max [94.6K]

Answer:

The time period was of 5 years.

Step-by-step explanation:

The formula to compute the simple interest is:

$SI=\frac{P\times r\times t}{100}$

The information provided is as follows:

$P_{1}=5000\\\\r_{1}=10\%\\\\P_{2}=6000\\\\r_{2}=10\%\\\\SI_{1}=S_{2}-500$

The time period is same for both the amounts.

Compute the time t as follows:

$SI_{1}=SI_{2}-500$

$SI_{2}-SI_{1}=500$

$\frac{P_{1}\times r_{1}\times t}{100}-\frac{P_{2}\times r_{2}\times t}{100}=500$

$\frac{6000\times 10\times t}{100}-\frac{5000\times 10\times t}{100}=500\\\\$

$600t-500t=500\\\\$

$100t=500\\$

$t=5\ \text{years}$

Thus, the time period was of 5 years.
