Given the table of values below, which of the following ordered pairs are
antiseptic1488 [7]

Answer:

(12,-2), (10,-1), (8,0), (6,1) and (4,2).

Step-by-step explanation:

If a function is defined as

f(x)=\{(x,y):x\in R,y\in R\}

then its inverse is defined as

f^{-1}(x)=\{(y,x):x\in R,y\in R\}

It means coordinates of ordered pairs are interchanged.

From the given table it is clear that the function passing through the points (-2,12), (-1,10), (0,8), (1,6) and (2,4).

Using the above definition, we can say that the inverse function passing through the points (12,-2), (10,-1), (8,0), (6,1) and (4,2).

Therefore, the required ordered pairs are (12,-2), (10,-1), (8,0), (6,1) and (4,2).

Answer to number 8? I and wondering the probability
Yuri [45]
The quantity you want is the area under the standard normal curve (with mean 100 and std dev 15) between 110 and 120.

According to my TI-83 calculator,

normalcdf(110,120, 100, 15) = 0.16, or 16%.

What is the probability of choosing a
sladkih [1.3K]

Answer:

Probability of choosing a penny at random is 1/5 or 0.2

Step-by-step explanation:

For many probabilities like this one, you have to add the total of materials or items together, even if they are different colors, shape, coin type, etc.

you have 12 pennies, 19 nickles, 14 dimes, and 15 quarters. This adds up to a total of 60 coins. Twelve of those are pennies.

You have twelve possible pennies to choose at random from a total of 60 in a bag.

So 12/60/ This simplifies to a probability of 1/5. If you divide 1 by 5 than it would be 0.2

The probability of choosing a penny from a bag of coins is 1/5, or 0.2.

Hope this helps

-15x=-4x... How to move the x to the left?
Delvig [45]
-15x=-4x

We know that adding zero wouldn’t change the value

-15x=-4x+0

Now we can add 4x (since that’s the opposite of the negative sign) to the other side

-11x=0

0 divided by 11 is 0

x=0
