ANSWER ASAP David, Egil and Frances share money in the ratio 2:7:9. Explain why Frances will always get half of any money they s

8090 [49]

Answer: 80$

Step-by-step explanation:

Step-by-step explanation:

We have been given that David, Egil and Frances share money in the ratio 2:7:9.

Let 2x, 7x and 9x be the amounts of money that David, Agil and Frances get respectively.

We are told that Frances gets $80 more than David. So we can write this information in an equation as:

9x=2x+80

Now let us solve for x.

9x-2x=80

7x=80

x=\frac{80}{7}

Now let us substitute x=\frac{80}{7} in 7x (amount of money that Egil gets).

\text{ Amount of money that Egil will get}=7\cdot \frac{80}{7}

Upon cancelling out 7 from numerator and denominator we will get,

\text{ Amount of money that Egil will get}=80

Therefore, Egil will get $80.

Solve 5[8-(9x-7)]+6x=0

trapecia [35]

<span>5[8 - (9x - 7)] + 6x = 0

5[8 -9x + 7] + 6x = 0

5(15 -9x) + 6x = 0

75 - 45x + 6x = 0

-39x = -75

39x = 75

x = </span> $\frac{75}{39}$ = 1.923076923076923 ≈ 1.92

A quality control inspector has drawn a sample of 14 light bulbs from a recent production lot. If the number of defective bulbs

LekaFEV [45]

Answer:

0.1979 or 19.79%

Step-by-step explanation:

If 20% of all bulbs are defective, there is a 20% chance of each bulb being defective and an 80% chance of each bulb not being defective.

This is a binomial probability model with probability of success (bulb being defective) of p=0.20.

In order for the lot to pass inspection, it must contain either zero or one defective bulb, the probability of one of these scenarios occurring is:

$Pass= P(d=0)+P(d=1)\\Pass= 0.80^{14}+14*0.20*0.80^{13}\\Pass=0.1979$

The probability that the lot will pass inspection is 0.1979 or 19.79%.
