<h3>
Answer: 4/13</h3>
=======================================================
Explanation:
There are A = 13 hearts and B = 4 copies of "7"
The count A+B = 13+4 = 17 may seem like it's the count of hearts or "7" cards, but we're double counting the 7 of hearts. So the true count is actually 17-1 = 16
There are 16 cards we want (either a heart or a "7") out of 52 total. Therefore, the probability is 16/52 = (4*4)/(4*13) = 4/13
Ten times greater. The 9 in 9000 stands for 9000, the 9 in 900 stands for 900. 9000/900 = 10

Answer: 1/1024
Step-by-step explanation:
When a fair coin is flipped the coin would show either head or tail meaning only 2 outcomes are possible. So, getting an head means 50% chance or 1/2 chance.
Now, it means chance for 10 times head every time= (1/2)^10
Chance= 1/1024
Chance= 0.00097
We are given the following function:

We are asked to do the following tranformations:
1. Shift down 5 units and left 77 units.
First, to shift a function down a number "n" of units we follow the next rule:

And, to shift a function "m" units to the left we use the following rule:

Applying both rules simultaneously we get:

2. Reflect about the y-axis.
The rule to reflect a function about the y-axis is the following:

The means that we will change "x" for "-x" in the function we are going to reflect. Applying the rule we get:

3. Compress vertically by a factor of 2.
To compress a function vertically by a factor "m" we multiply the entire function by 1/m, like this:

Applying the rule we get:

And thus we get to the final function.
