Answer:
○ -1
Step-by-step explanation:
Looking closely at this piecewise function, when the line on the left-hand side intersects at <em>-</em><em>3</em><em> </em><em>=</em><em> </em><em>y</em><em>,</em><em> </em><em>x</em><em> </em>is -1.
I hope this helps, and as always, I am joyous to assist anyone at any time.
Two negatives make a positive so, -13 - (-49) equals -13 + 49, or 49-13, they are all the same thing, all equal to 36.
Written out, this would be (x / 7) - 10 < -6
solved, it would be x < 28
Answer:
0.06597
Step-by-step explanation:
Given that thirty-seven percent of the American population has blood type O+
Five Americans are tested for blood group.
Assuming these five Americans are not related, we can say that each person is independent of the other to have O+ blood group.
Also probability of any one having this blood group = p = 0.37
So X no of Americans out of five who were having this blood group is binomial with p =0.37 and n =5
Required probability
=The probability that at least four of the next five Americans tested will have blood type O+
= 
A = lw
Plug in what we know:
25/54 = (5/9)w
Divide 5/9 to both sides or multiply by its reciprocal, 9/5:
25/54 * 9/5 = w
Multiply the numerators and denominators together:
225/270 = w
Simplify:
<span>w = 5/6</span>
