Janet = 7.55 x 15(hours) = 113.25
Kelsey = 15.10 x 15(hours) = 226.50
Ty = 13.85 x 15(hours) = 207.76
To gets Kelsey’s wage per hour you do 7.55 x 2 and to get ty you do 15.10(Kelsey’s wage per hour) - 1.25 which is 207.76
Answer: Volume of cylinder is (3.14) x (radius squared) times height, or nr^2h
Step-by-step explanation:
Answer: 554
Step-by-step explanation:
Formula we use to find the sample size :
Given : Standard deviation :
Margin of error : E=one quarter hour = 0.25 hour
Two-tailed , Critical value use for 0.95 degree of confidence:
i.e.
Hence, the required sample size = 554
i.e. 554 executives should be surveyed.
"Rationalizing the denominator" of a number is exactly what its title implies: turning its denominator into a rational number.
For an example, let's take the fraction 1/√2. We call √2 <em>irrational</em> because it cannot be expressed as a <em>ratio </em>of two integers. Oftentimes when we have irrational numbers like √2 in the denominator, it helps to perform a little bit of algebraic manipulation on them to make the denominator rational. Here's where that "form of 1" comes in. Remember that, as a rational number, 1 can be expressed as n/n, where n is any number. We can use this fact to rationalize the denominator of 1/√2 <em />by multiplying it by √2/√2, which is equivalent to 1.
When we multiply the two together, we get:
Crucially, multiplying by 1 in the form of √2/√2 <em>keeps the fraction's value the same</em>, since 1 times any number just equals that same number. If we weren't multiplying but some form of 1, we'd change the number entirely, making the whole attempt at rationalizing the denominator pointless.
Answer: The slope of the line = 4.
Step-by-step explanation:
We know that ,
Slope of a line passes through and =
Here , the line passes through points (2,18) and (8,42).
Then the slope of the given line =
Hence, the slope of the line = 4.
