Answer: Fraction of the estate Debra will received is
Step-by-step explanation:
Since we have given that
Amount shared by Debra and Lan = $1000,000
Amount received by Lan = $125,000
According to question, Debra received the rest.
So, Amount received by Debra is given by
Fraction of the estate Debra will receive is given by
Hence, Fraction of the estate Debra will received is
Answer:
A ) The Equation of the circle (x−10)2+(y−24)2=676
Step-by-step explanation:
step1:-
The equation of the circle whose center is (a,b) and radius r is
in this circle equation centre is (g,f) = (10,24)
and formula of radius of a circle is
r =
Step2:-
The Equation of the circle (x−10)^2+(y−24)^2=676
Answer:
P(6) = 0.6217
Step-by-step explanation:
To find P(6), which is the probability of getting a 6 or less, we will need to first calculate two things: the mean of the sample (also known as the "expected value") and the standard deviation of the sample.
Mean = np
Here, "n" is the sample size and "p" is the probability of the outcome of interest, which could be getting a heads when a tossing a coin, for instanc
So, Mean = n × p = (18) ×(0.30) = 5.4
Next we we will find the standard deviation:
Standard Deviation =
n = 18 and p = 0.3 "q" is simply the probability of the other possible outcome (maybe getting a tails when flipping a coin), so q = 1 - p
Standard Deviation =
= 1.944
Now calculate the Z score for 6 successes.
Z = ( of successes we're interested in - Mean) ÷ (Standard Deviation)
=(6-5.4) ÷ (1.944) = 0.309
we have our Z-score, we look on the normal distribution and find the area of the curve to the left of a Z value of 0.309. This is basically adding up all of the possibilities for getting less than or equal to 6 successes. So, we get 0.6217.
