The value of the expression 2-(-4)+(-y)^2-(-4)+(-y)^2 after substituting y = 7 is 108

<h3>Evaluation of Expression</h3>

The given expression is:

2-(-4)+(-y)^2-(-4)+(-y)^2

Simplifying the expression, we have:

2+4+y^2+4+y^2\\\\2y^2+10

Substitute y = 7 into the simplified expression

2(7)^2+10\\\\=2(49)+10\\\\=98+10\\\\=108

Therefore, after substituting y = 7, into the expression 2-(-4)+(-y)^2-(-4)+(-y)^2, the resulting value is 108

His error is in step 3. The variable x is being multiplied by -7 and therefore he should have divided both sides by -7, not 7 as he did.

58+28=86.
8+8=16
5+2=7
take the 1 from 16 and add it onto the 7
1+7=8: thats the tens place.
Now we only have 6. So thats the ones place. Combine the two numbers and you get 86.

An experiment consists of rolling a single die and selecting a card from a standard deck. Use this information to answer the fol
Alexus [3.1K]

Answer:

1/160

Step-by-step explanation:

Assuming that you want to roll a 5 and then select the ace of hearts that would make this a sequence of events. In order to find the probability of this happening, you would need to multiply the probability of each of these events happening separately with one another.

Since there are a total of 6 possible outcomes when rolling a die (1,2,3,4,5,6) which rolling a 5 is only one of the options. Meaning that the probability of rolling a 5 is 1/5.

In a deck of cards, there are a total of 32 cards in the deck and only 1 of those cards is an ace of hearts. Meaning that the probability of getting the ace of hearts is 1/32. Now we simply multiply these two probabilities together to get the probability of the sequence.

1/5 * 1/32 = 1/160
