A * 4 = E........A = E / 4
B / 4 = E........B = 4E
C + 4 = E......C = E - 4
D - 4 = E.......D = E + 4
A + B + C + D = 100
(E/4) + (4E) + (E - 4) + (E + 4) = 100
E/4 + 6E = 100 ....multiply by 4
E + 24E = 400
25E = 400
E = 400/25
E = 16 <===
Answer:
0,3
Step-by-step explanation:
Well 0,3 is the only one that is on here... I apologize if I am wrong!
This problem is easier solved by finding the probability that she does NOT do her homework both Monday and Tuesday, which is obtained by the multiplication rule.
P(no HW on Monday) = 1-0.75 = 0.25
P(no HW on Tuesday) = 1-0.75 = 0.25
P(no HW on both Monday and Tuesday) = 0.25*0.25=0.0625
[by the multiplication rule]
This means that the rest of the time (1-0.0625=0.9375) Elsie does her homework either Monday, or Tuesday, or both days.
=>
P(HW either Monday, Tuesday, or both) = 0.9375
(note: in current English, Monday or Tuesday means "either Monday, Tuesday, or both days")
Your missing the diagram. Thus, I will try my best to help
Answer/Step-by-step explanation:
Given;
The diagram below shows how much time Antoine spends doing different activities each day.
How many hours does Antoine sleep in a day?

Answer:
79
Step-by-step explanation:
To find the value of
, when x = 3, simply plug in the value of x in the expression and solve as follows:
![10(3)^2 – 7(3) + 10](https://tex.z-dn.net/?f=%2010%283%29%5E2%20%E2%80%93%207%283%29%20%2B%2010%20)
![10(9) – 21 + 10](https://tex.z-dn.net/?f=%2010%289%29%20%E2%80%93%2021%20%2B%2010%20)
![90 – 21 + 10](https://tex.z-dn.net/?f=%2090%20%E2%80%93%2021%20%2B%2010%20)
![79](https://tex.z-dn.net/?f=%2079%20)
The value of
, when x = 3, is 79
