The inner orbit is designated by the number 1
Answer:
Approximate probability that the number of households that use the Internet for banking in a sample of 1000 is less than or equal to 130 is less than 0.0005% .
Step-by-step explanation:
We are given that let X be the number that do some or all of their banking on the Internet.
Also; Mean,
= 310/1000 or 0.31 and Standard deviation,
= 14.63/1000 = 0.01463 .
We know that Z =
~ N(0,1)
Probability that the number of households that use the Internet for banking in a sample of 1000 is less than or equal to 130 is given by P(X <= 130/1000);
P(X <=0.13) = P(
<=
) = P(Z <= -12.303) = P(Z > 12.303)
Since this value is not represented in the z table as the value is very high and z table is limited to x = 4.4172.
So, after seeing the table we can say that this probability is approximately less than 0.0005% .
Answer:
Equations:
<u>Mia: 10 + 10x = y</u>
<u>Julie: 100 - 5x = y</u>
Solved: <u>(6, 70)</u>
Step-by-step explanation:
Mia: 10 + 10x = y
She already has 10 (<u>10</u>) and gains 10 (<u>+10</u>) per day (<u>x</u>). Total is y gained.
Julie: 100 - 5x = y
She already has 100 (<u>100</u>) and loses 5 (<u>-5</u>) per day (<u>x</u>). Total is y gained.
Then I simply solve
10 + 10x = y
100 - 5x = y
Resulting in (6, 70)
W: (5,9)
X: (7,8)
Y: (9,2)
Z: (2,5)
hope this helps! tell me if i got anything wrong!
