Answer:

.

c)"At least 1 O+" is equivalent to "not none O+" (forgive the incorrect English).

P(not none O+)+P(none O+)=1

P(not none O+)=1-P(none O+)

P(not none O+)=1-0.00491

P(at least 1 O+)=0.995

What is the answer ?
MrRissso [65]

The angle B will be equal to ∠B=53.13 degrees.

<h3>What is the triangle?</h3>

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

It is given that:-

Three sides of the triangle are:- a= 3, b=4  and c =5

The angle B will be calculated by the following formula;-

\angle B=Cos^{-1}\dfrac{a^2+c^2-b^2}{2ac}\\\\\\\angle B=Cos^{-1}\dfrac{3^2+5^2-4^2}{2\times 3\times 5}\\\\\\\angle B=Cos^{-1}(0.6)\\

∠B=53.13 degrees

Hence the angle B will be equal to ∠B=53.13 degrees.

The original price of an item is $130. The item is on a discount of 1/5 off the original price. You then pay a sales tax of 10%.
ahrayia [7]
Hello!

First, find 1/5 of $130, and then subtract that from the original price of the item, because it is a discount.

Divide the price of the item by 5.

130 ÷ 5 = 26

130 - 26 = 104

So, the price of the item (not including tax) is $104. Now, we must calculate the sales tax and then add that onto the price of the item, as tax is money collected by the government.

To calculate the tax, multiply the discounted price of the item by the percentage of tax, and then add it.

104 × 10% = 10.4

104 + 10.4 = 114.4

ANSWER:

The amount of money you paid fot the item is $114.4.
