Answer:

Step-by-step explanation:

Arithmetic expressions are best evaluated using a reliable calculator. The Google calculator always follows the Order of Operations, so can give you a good answer to such questions.

(1/4)^-2 - (5^0)(2)(1^-1)

= 16 - (1)(2)(1) . . . . evaluate the exponents first

= 16 -2 . . . . . . . . . evaluate the product next

= 14 . . . . . . . . . . . finally, evaluate the sum

___

The rule of exponents is ...

a^-b = 1/(a^b)

Ellen has a bag with 3 red marbles and 2 blue marbles in it. She is going to randomly draw a marble from the bag 300 times, putt

sweet [91]

Answer:

No. of times Ellen draws a blue marble = 120

Step-by-step explanation:

No. of red marbles = 3

No. of blue marbles = 2

$\text{Probability of drawing a blue marble = }\frac{\text{No. of possible outcomes}}{\text{Total no. of outcomes}}\\\\P(B)=\frac{2}{5}\\\\No. of draws (n) = 300\\\text{So, total probability = }n\times P(B)\\\\=100\times \frac{2}{5}=120.$

So, the required probability is 120.

The 6 angles with vertex P are:

Angle APB
Angle APC
Angle APD
Angle BPC
Angle BPD
Angle CPD

The letter P must be in the middle since this location is the vertex. Something like angle BPA is the same as angle APB. We can swap the order of the outer letters without any change to the angle itself. Effectively, this means each angle has two possible names.
