Help i'm doing missing assignments and this is a lil tricky.

Answer: 25.12 ft

To find the circumference of a circle, multiply the diameter with π (pi)

Formula: 2πr (2 × radius) (π = 3.14)

In the problem...

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

We can multiply 3.14 by 8 to get the circumference.

3.14 × 8 = 25.12

Hence, 25.12 is the answer, but we can do it another way.

Let me know if you have any questions.

~ Lily, from Brainly.

<em>Note to asker: Hi there, make sure to write down these formulas!</em>

<em />

<em>Circumference: 2πr</em>

<em />

<em>Area: πr²</em>

<em />

<em>Radius: </em>\frac{diameter}{2}<em />

<em />

<em>Diameter: radius × 2</em>

H/4 + 7z <br><br><br> Variables <br><br><br> h= 8 z = 9
kramer

Step-by-step explanation:

what do we need to do ?

just calculate the value of the expression by using the given values for the variables ?

what's the problem ? this is just basic calculation.

8/4 + 7×9 = 2 + 63 = 65

remember (please, for your life !) that multiplication and division always happens before any addition or subtraction (except for the case, where brackets force us in a different direction).

An industrial/organizational psychologist wants to improve worker productivity for a client firm, but first she needs to gain a
Illusion [34]

Answer:

a) Standard Error = 0.6578

b) 99% confidence interval = (7.303, 10.697)

c) A population mean of 8.5 hours would not surprise the psychologist as this is within the confidence interval.

Step-by-step explanation:

a) Standard error = Standard deviation/√n

n = sample size = 250

Standard deviation = 10.4

Standard error = (10.4/√250)

Standard error = 0.6578

b) 99% confidence interval

Confidence interval = (Sample mean) ± (Margin of error)

Sample mean = 9 hours

Margin of Error = (critical value) × (standard error or standard deviation of the distribution of sample means)

Critical value for a 99% confidence interval = 2.58 (from the z-tables)

Standard error or standard deviation of the distribution of sample means = 0.6578

margin of error = 2.58 × 0.6578 = 1.697

Confidence interval = 9 ± 1.697

Lower limit of the confidence interval = 9 - 1.697 = 7.303 hours

Upper limit of the confidence interval = 9 + 1.697 = 10.697 hours

99% confidence interval = (7.303, 10.697)

c) A population mean of 8.5 hours would not surprise the psychologist as this is within the confidence interval.

Hope this Helps!!!
