Answer:
Sardar has a 29% chance of inheriting at least some money.
Step-by-step explanation:
Since Sardar has two old rich aunts, Betty and Gwenda, assuming they will both die before he does, for each aunt, Sardar thinks the chance that she will leave him some money if she dies first is 1/3, but Sardar thinks that if Gwenda dies first, the chance that Betty will leave him money is only 1/4, and if Betty dies first, the chance Gwenda will leave him money is also 1/4, to determine what is the probability that he will inherit at least some money by the time they both die the following calculation must be performed:
(1/3 + 1/4) / 2 = X
(0.333 + 0.25) / 2 = X
0.58333 / 2 = X
0.29 = X
Therefore, Sardar has a 29% chance of inheriting at least some money.
12:36 for the first one
6:21 for the second one
And 21:15 because let's say that for every 7 cans that a group gets , the other group gets 5
Answer:
20
Step-by-step explanation:
If you fill those variables in, you will get 3 times 6 + 2 times 4 over 3-2 squared
you do your operations to get 20 over 1 which equals to 20
Answer:
494000
Step-by-step explanation:
2.5 percent of 130000 is 3250, so 3250 x number of years. There are 112 years in between. So 112 x 3250=364000. 364000 + 130000=494000.
Answer: ![-\sqrt{2}](https://tex.z-dn.net/?f=-%5Csqrt%7B2%7D)
Step-by-step explanation:
The trigonometric function secant is the reciprocal of cosine:
![sec(\alpha)=\frac{1}{cos(\alpha)}](https://tex.z-dn.net/?f=sec%28%5Calpha%29%3D%5Cfrac%7B1%7D%7Bcos%28%5Calpha%29%7D)
For
