Mathematics

WINSTONCH [101]3 years ago
6 0

Answer:

The rate of sales tax is 6%.

Step-by-step explanation:

First you must subtract 12.50 from 13.25

This brings you to .75

Then, divide .75/12.50 to get 0.06 which is equivalent to 6 percent.

True or false: any nonzero integers, the product and the quotient have the same sign. Why?
serg [7]
False. This is because no matter what the number is, the properties of multiplication and division stay the same. So, if one odd and even number multiply/divide, then the answer will be negative. But, if two numbers of the same sign (both either negative or positive) are divided/multiplied, they will both be positive. Therefore, the result is not always the same sign as the starting integers

Hope this helped! :D

Anyone think they could help me with this ?
topjm [15]

Answer:

10

Step-by-step explanation:

As we can see in hint through it we can identify that it is right angled triangle so here

AB = 6

FE = BC ( being corresponding sides of congruent triangle)

BC = 8

Now In triangle ABC

perpendicular (p) = 6

base (b) = 8

hypotenuse (h) = ?

By using Pythagoras theorem we get

h = √ p² + b²

= √ 6² + 8²

= √ 100

= 10

So Now

AC = h = 10

Hope it will help :)

Suppose that telephone calls arriving at a switchboard follow a Poisson process with an average of 5 calls per minute. What is t
postnew [5]

Answer:

The correct answer is "0.0842".

Step-by-step explanation:

Given:

X = 5

By using the Poisson's distribution formula, we get

The probability will be:

⇒ P(x=2)=\frac{\lambda^x.e^{-\lambda}}{x!}

By substituting values, we get

                   =\frac{(5)^2\times e^{-5}}{2!}

                   =\frac{25\times e^{-5}}{2!}

                   =0.0842
