grigory [225]
3.6% compounded quarterly=.036/4=0.009 per period
FV=5600(1+.009)^4y where FV=future value, and y is time, in years. So:
FV(6)=5600(1.009)^4(6)=5600(1.009)^24=$6943.46

Suppose the average commute time of your employees is unknown. The standard deviation of their commute time is estimated as 22.8
nexus9112 [7]

Answer:

96 employees

Step-by-step explanation:

Given that the standard deviation = 22.8

The width in the question = 12

We solve for the margin of error E.

E = width / 2

= 12/2 = 6

At 99%

Alpha = 1-0.99

= 0.01

Alpha/2 = 0.01/2 = 0.005

Z0.005 = 2.576

Sample size n

= ((2.576x22.8)/2)²

= 95.8

= 96

The number of employees is 96

Thank you!

Can anyone answer this please? I need help
BARSIC [14]

Answer:

84 cm squared, 30 cm squared, 18 cm squared

Step-by-step explanation:

Formula for triangle area= 1/2 Base * Height

Area for triangle ABD= 1/2 (12cm)*(14cm)

                                   =84 cm squared

Area for triangle BC(orange triangle)= 1/2 (6cm)*(10cm)

                                   =30 cm squared

BC=  half of BD

Area for triangle CD(Green  triangle)= 1/2 (6cm)*(4cm)

                                   =12 cm squared

Travka [436]

9 inches across the floor Brendan rolls his ball if Sydney rolls a ball 63 inches across the floor.

<h3>What is linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

Sydney rolls a ball 63 inches across the floor. This is 7 times the distance that Brendan rolls his ball across the floor.

Sydney rolls = 7n

Here n represent the number of inches Brendan rolls his ball.

63 = 7n

n = 63/7 = 9 inches

Thus, 9 inches across the floor Brendan rolls his ball if Sydney rolls a ball 63 inches across the floor.
