Answer:

so his total pay for Saturday would be $104.50

Step-by-step explanation:

He works 5 hours at $11 per hour which gets a total of 55$

He also works 3 hours of overtime where he gets payed 1.5x pay

11 x 1.5 = 16.5 (10x1.5 = 15 1x1.5 = 1.5)

Answer:

d. 0.133

Step-by-step explanation:

-Standard error is calculated using the formula:

$E=\frac{\sigma}{\sqrt{n}}\\\\\sigma-=standard \ deviation\\n=sample \ size$

#We substitute the given values in the formula to solve for E:

$E=\frac{\sigma}{\sqrt{n}}\\\\=\frac{1.2}{\sqrt{81}}\\\\=0.133$

Hence, the standard error is 0.133 and the correct option is d

Which number is irrational? <br> A: √9<br> B: √8<br> C: 0.3333<br> D: 2/3<br><br> Answer fast please

Arisa [49]

$\sqrt{8}$ is an irrational number ⇒ answer B

Step-by-step explanation:

Let us explain the meaning of:

A rational number is a number that can be written as a fraction
An irrational number is a number that cannot be expressed as a fraction

Examples:

Rational numbers : 10 , $\frac{2}{5}$ , 0.333

Irrational numbers : π , √8 , ∛25 , (2 + √5) , $\frac{\sqrt{7}}{3}$

∵ $\sqrt{9}=3$

∵ 3 is a rational number

∴ $\sqrt{9}$ is a rational number

∵ $\sqrt{8}$

∵ There is no square root of 8

∴ $\sqrt{8}$ is an irrational number

∵ 0.3333 can be expressed as $\frac{3333}{10000}$

∴ 0.3333 is a rational number

∵ $\frac{2}{3}$ is a fraction

∵ All fractions are rational numbers

∴ $\frac{2}{3}$ is a rational number

$\sqrt{8}$ is an irrational number

1) The accumulated amount after six years and the total interest that Trevor will receive if the interest rate is 4.5% per annum simple interest after 6 years are <u>R25,400</u> and <u>R5,400</u> respectively.

2) The accumulated amount after six years and the total interest that Trevor will receive if the interest rate is 4.5% per annum compound interest after 6 years are<u> R26,045.20</u> and <u>R6,045.20</u> respectively.

<h3>Data and Calculations:</h3><h3>Simple Interest:</h3>

Principal = R20,000

Investment period = 6 years

Interest rate = 4.5%

Simple interest for 6 years = R5,400 ($20,000 x 6 x 4.5%)

Principal + Interest = R25,400 (R20,000 + R5,400)

<h3>Compound Interest:</h3>

Principal = R20,000

Investment period = 6 years

Interest rate = 4.5%

N (# of periods) = 6 years

I/Y (Interest per year) = 4.5%

PV (Present Value) = R20,000

PMT (Periodic Payment) = R0

<u>Results</u>:

FV = R26,045.20

Total Interest = R6,045.2
