Answer:

$0.9613$

Step-by-step explanation:

we know that

Depending on your calculator, you enter the degree and then press the trig button or the other way around. Also, make sure the mode of your calculator is in DEGREES

we have

$sin(106^o)=0.9613$

An agency is studying the income of store managers in the retail industry. A random sample of 25 managers reveals a sample mean

aalyn [17]

Answer:

The Confidence Interval = ($44,745.55 , $46,094.45)

Step-by-step explanation:

The formula for Confidence Interval =

Confidence Interval = Mean ± z × Standard deviation/√n

Where n = number of samples = 25 managers

Standard deviation = $2,050

Mean = $45,420

z = z score of the given confidence interval

= z score of 90% confidence interval

= 1.645

Confidence Interval = $45,420 ± 1.645 × $2,050/√25

= $45,420 ± 1.645 × $2,050/5

= $45,420 ± 674.45

Confidence Interval =

$45,420 - 674.45 = $44,745.55

$45,420 + 674.45 = $46,094.45

Therefore, the Confidence Interval = ($44,745.55 , $46,094.45)

Answer:

-512

Step-by-step explanation:

The laws of exponents state that multiplying two exponents together of the same base allows you to add the exponents. Raising an exponent to another power allows you to multiply the exponents. In this case. you have $(-2)^3*((-2^3))^2$ . First, you take the second term, or $((-2^3))^2$ and simplify it. Since you're raising an exponent to another exponent you have $(-2)^(3*2)$ , or $(-2)^6$ . Now, you multiply by $(-2)^3$ . Since they both have the same base, you can add the exponents to get $(-2)^9$ . Since $(-2)^9$ is raised to an odd exponent, you know you're answer is going to be negative. $2^9$ is 512, so that negative would be -512. If you're looking for an expression for this, you can write $(-2)^9$
