Assuming 6 is the radius, we can use the formula to find the area of a whole circle, which is πr2

So it’s π6^2

Which is 113.1. BUT it’s a semi circle, so just divide by 2. So the answer should be 56.52 units squared.

The heights of American men are normally distributed. If a random sample of American men is taken and the confidence interval is

solmaris [256]

Answer:

Step-by-step explanation:

Given the confidence interval of the heights of american heights given as (65.3,73.7);

Lower confidence interval L = 65.3 and Upper confidence interval U = 73.7

Sample mean will be the average of both confidence interval . This is expressed mathematically as $\overline x = \frac{L+U}{2}$

$\overline x = \frac{65.3+73.7}{2}\\\overline x = \frac{139}{2}\\\overline x = 69.5$

Hence, the sample mean is 69.5

Instructions: Factor 715 as a product of primes.

Drupady [299]

Answer:

{1, 5, 143}

Step-by-step explanation:

715 is evenly divisible by 5, so one factor of 715 is 5 and the next is 715/5, or 143. 143 is not factorable further. Thus, the factors of 715, in ascending order, are 1, 5 and 143.

Vance bought 2 packages of large beads

VashaNatasha [74]

The no. of more buttons than beads that Vance bought is 1 (medium package)

<h3>What is an algebraic expression?</h3>

In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.).

<h3>How to solve algebraic expressions? </h3>

A General Rule for Equation Solving

B Remove parenthesis from either side of the equation and combine similar phrases to make it simpler.

C To separate the variable term on one side of the equation, use addition or subtraction.

D To find the variable, use division or multiplication.

Given:- The no: of package of large beads is 2

The no: of the package of medium beads is 1

The no: of the package of large buttons is 2

The no: of the package of medium buttons is 2

Hence large packages

2(buttons)-2(beads)=0

For medium packages

2(buttons)-1(beads)=0

therefore, the no of more buttons than beads is 1 medium package
