Divide 24 by 3 to figure out how many cubes are in 1 step (24/3=8). Now divide 84 by 8 to figure out how many steps he built with 84 cubes (84/8=10.5). Ron's second staircase has 10 and a half steps :)

gtnhenbr [62]

Answer:

99\% CI=4.1602 \pm 0.0009

Step-by-step explanation:

From the question we are told that:

Sample size n=8

Mean \=x=4.1602

Standard deviation \sigma=0.001gram

Generally 99\% confidence from table  is mathematically given by

 99\% CI=4.1602 \pm *2.576*\frac{0.001}{\sqrt{{8}}}

 P(-z

 Z_{\alpha/2}=2.576

Generally the equation for 99\% confidence level (CI)  is mathematically given by

 99\% CI=\=x \pm Z_{\alpha/2*\frac{\sigma}{\sqrt{{n}}}

 99\% CI=4.1602 \pm 0.0009

What is the area of the rectangle with the given dimensions? *
exis [7]

Given:

The dimensions of a rectangle are 2x-5 and 3x+3.

To find:

The expression that represents the area of the rectangle in simplest terms.

Solution:

Area of a rectangle is:

Area=Length\times Width

The dimensions of a rectangle are 2x-5 and 3x+3. So, the area of the given rectangle is:

Area=(2x-5)\times (3x+3)

Area=2x(3x)+2x(3)-5(3x)-5(3)

Area=6x^2+6x-15x-15

Area=6x^2-9x-15

Therefore, the correct option is F, i.e., 6x^2-9x-15.

How do you calculate gross pay net pay and employee benefits
Sonja [21]

Gross pay is the amount of money your employees receive before any taxes and deductions are taken out. For example, when you tell an employee, “I'll pay you $50,000 a year,” it means you will pay them $50,000 in gross wages.

Hope this helps!!
