Multiply the employee's current pay rate by that decimal. So it is 31.05 if i'm correct
They are both right triangles so we can use the Pythagorean
theorem to solve.
6. B = sqrt(15^2-9^2)
B = 12 mm
7. B = sqrt(26^2-10^2)
B = 24 Cm
Part (a)
The raw score is x = 25. The mean and standard deviation are mu = 45 and sigma = 13.8 respectively.
The z score is computed with the formula below
z = (x-mu)/sigma
z = (25-45)/13.8
z = -1.449275 approximately
z = -1.45 is the final answer
========================================================
Part (b)
We want the z score to be larger than 2. So z > 2.
This is the same as wanting the expression (x-mu)/sigma to be larger than 2
(x-mu)/sigma > 2
(x-45)/13.8 > 2
x-45 > 2*13.8
x-45 > 27.6
x > 27.6+45
x > 72.6
If a customer's age is greater than 72.6 years, then this means they have a z score greater than 2. We can say they are more than 2 standard deviations above the mean.
If you need a whole number, then I'd round up to 73. Or you could pick any age larger than this.
Answer:
2000
Step-by-step explanation:
Hello,
A or C means 2 ways
and then a digit means 10 ways 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
so in total we have 2*10*10*10 = 2000 possible codes
Hope this helps
Answer:
1.17
Step-by-step explanation:
(MUCH BETTER!)
From the definition of the sin of an angle, you know:
sin(45°) = AC/AB = 4/AB ⇒ AB = 4/sin(45°) ≈ 5.6569
sin(63°) = AC/AD = 4/AD ⇒ AD = 4/sin(63°) ≈ 4.4893
Then the difference AB-AD is:
AB -AD = 5.6569 -4.4893 = 1.1676
AB -AD ≈ 1.17 units
Sorry this took me so long to answer!
