John withdraws $40.00 from her savings account each month. What integer represents the net effect on her balance after 5 months?

lina2011 [118]

Answer:

The net effect of amount in John account after 5 months is $A - $200

Step-by-step explanation:

Given as :

The amount of money withdraws by John each month from his account = $40

Let The total amount of money did John had in his account = $A

Let the amount left in John account after 5 months of withdraw = $x

So, According to question

∵ Each month the money withdraw from account = $40

∴ In 5 months , the money withdraw = $40 × 5

I.e In 5 months , the money withdraw = $200

So, The left money in account after withdraw in 5 months = $A - The amount withdraw in 5 months

I.e x = $A - $200

So, The balance in account after 5 months = x = $A - $200

Hence, The net effect of amount in John account after 5 months is $A - $200 Answer

A person on a moving sidewalk travels 40 feet in 8 seconds. The moving sidewalk has a length of 200 feet. How long will it take

beks73 [17]

Answer:

The man covers 200 ft in 40 seconds.

Step-by-step explanation:

A person is moving on the sidewalk from one end to the other end.

He walks 40 feet in 8 seconds.

Therefore his speed = $\frac{distance covered}{time}$

= $\frac{40}{8}$

= 5 ft/ $s^{2}$

He covers the sidewalk distance at a rate of 5 feet every second.

To calculate the time taken to cover 200 ft,

time = $\frac{distance to be covered}{speed}$

time = $\frac{200}{5}$

time = 40 seconds

Hence the man covers 200 ft in 40 seconds.

Suppose that the ages of members in a large billiards league have a known standard deviation of σ = 12 σ=12sigma, equals, 12 yea

asambeis [7]

Answer:

$n\geq 23$

Step-by-step explanation:

-For a known standard deviation, the sample size for a desired margin of error is calculated using the formula:

$n\geq (\frac{z\sigma}{ME})^2$

Where:

$\sigma$ is the standard deviation
$ME$ is the desired margin of error.

We substitute our given values to calculate the sample size:

$n\geq (\frac{z\sigma}{ME})^2\\\\\geq (\frac{1.96\times 12}{5})^2\\\\\geq 22.13\approx23$

Hence, the smallest desired sample size is 23
