Answer:
the third
Step-by-step explanation:
Answer:
P (X≤1) = 0.000
Step-by-step explanation:
Data given:
p = 79% = 0.79
q = 1 - 0.79 = 0.21
n = 16
P (no more than 1 in 16 adults) = P (X≤1)
P (X≤1) = P (X=0) + P (X=1)
We can find the probability by using binomial functions:
![P=\frac{n!}{x!(n-x)!}p^x(1-p)^{n-x}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7Dp%5Ex%281-p%29%5E%7Bn-x%7D)
<h3>P(X=0):</h3>
P(X=0) = (16! / 0!(16-0)!) · 0.79⁰ · 0.21¹⁶
Use calculator to solve:
P(X=0) = 0.000000000798
<h3 /><h3>P(X=1):</h3>
P(X=1) = (16! / 1!(16-1)!) · 0.79¹ · 0.21¹⁵
Use calculator to solve:
P(X=1) = 0.000000034506
<h3>P(X≤1)</h3>
P (X≤1) = P (X=0) + P (X=1)
P (X≤1) = 0.000000000798 + 0.000000034506
P (X≤1) = 0.00000003530
P (X≤1) = 0.000
As 1 is a very low number, its probability is very small
Answer:
x = -1
Step-by-step explanation:
Given: ![f(x) = - 3x + 3](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20-%203x%20%20%2B%203)
Solve for x, When: ![f(x) = 6](https://tex.z-dn.net/?f=f%28x%29%20%3D%206)
Step by step:
![- 3x + 3 = 6](https://tex.z-dn.net/?f=%20-%203x%20%2B%203%20%3D%206)
![- 3x = 6 - 3](https://tex.z-dn.net/?f=%20-%203x%20%3D%206%20-%203)
![- 3x = 3](https://tex.z-dn.net/?f=%20-%203x%20%3D%203)
![x = 3 \div - 3](https://tex.z-dn.net/?f=x%20%3D%203%20%5Cdiv%20%20-%203)
![\boxed{\green{x = - 1}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cgreen%7Bx%20%3D%20%20-%201%7D%7D)
Answer:
100
Step-by-step explanation:
7 - (-93) = 100
-93 - (-193) = 100
-193 - (-293) = 100
As we can see, we get 100 for subtracting them all.
Best of Luck!
