Answer:
.5 or (1/2)
.5 or (1/2)
2.5 or (5/2)
Step-by-step explanation:
all you really have to do is mulitply the numbers by .5
1*.5= .5
5*.5= 2.5
Answer:
x = -4
Step-by-step explanation:
(x - 4) = 2x
We need an x that when is subtracted by 4 is equal to multiplying it by 2
((-4) - 4) = 2(-4)
(-8) = (-8)
Therefore x = -4

<h2>
The required probability is 0.1224.</h2>
Step-by-step explanation:
Here, given:
The probability of having 0 dental checkup = 0.3
The probability of having 1 dental checkup = 0.6
The probability of having 2 dental checkup = 0.1
Number of people chosen at random = 7
So, the number of ways 2, 4 and 1 checkup are : ![(\frac{7!}{2! \times 4! \times 1!} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B7%21%7D%7B2%21%20%5Ctimes%204%21%20%20%5Ctimes%201%21%7D%20%29)
Now, the combined probability that two will have no checkups, four will have one checkup, and one will have two checkups in the next year
= ![(\frac{7!}{2! \times 4! \times 1!} ) \times (0.3)^2 \times (0.6)^4 \times (0.1)^1 = 0.1224](https://tex.z-dn.net/?f=%28%5Cfrac%7B7%21%7D%7B2%21%20%5Ctimes%204%21%20%20%5Ctimes%201%21%7D%20%29%20%5Ctimes%20%280.3%29%5E2%20%5Ctimes%20%280.6%29%5E4%20%5Ctimes%20%280.1%29%5E1%20%20%3D%20%200.1224)
Hence, the required probability is 0.1224.
Answer:
406.35
Step-by-step explanation:
40 times $9.45=378
2 times (9.45times1.5)= 28.35
28.35+378= 406.35
