Answer:
10
Step-by-step explanation:
in scientific notation a number cant be greater than 10. so you have to move the decimal to make it under 10.
Answer: No, the events are not mutually exclusive
Work Shown:
P(A and B) = P(A) + P(B) - P(A or B)
P(A and B) = 0.51 + 0.79 - 0.66
P(A and B) = 0.64
Since the result is not zero, this means the events are not mutually exclusive.
Mutually exclusive events are ones that cannot happen at the same time. Example: getting a "2" and a "3" on the same roll of a number cube.
<h3>Answer</h3><h2>{EQUATION}</h2>
<h3>*Twice a number increased by four is ten.</h3><h3>*The difference of a number and 2 is 5. </h3>
<h2>{EXPRESSION}</h2>
<h3>*Seven less than half a number squared.</h3><h3>*The difference of a number and two is five. </h3>
You flip the signs when you are dividing by a negative value.
-2x+3>15
-2x>15-3
-2x>12
x<12/-2
x<-6
Now to test this
Try putting x in the original equation when it is -5.
-2(-5)+3>15
10+3>15
13>15
This is false because our answer says x is less than -6.
Now any value less than -6 will work so let's go with -7.
-2(-7)+3>15
14+3>15
17>15
This result is True.
Hope this helps out!
