Answer:

The total money raised by two Friends in fundraiser is $ ( 17 d + 15).

Step-by-step explanation:

Money raised by one friend = $ (9 d + 10)

Money raised by other friend = $ (8 d + 5)

Now, Total Money raised together

= Money Raised by friend 1 + Money raised by friend 2

= $ (9 d + 10) + $ (8 d + 5)

= ( 9d + 8d) + ( 10 + 5)

= 17 d + 15

or, Total Money = ( 17 d + 15 )

Hence, the total money raised by two Friends in fundraiser is $ ( 17 d + 15).

Nuetrik [128]

Let p be 0.831 denote the percentage of defective welds and q be 0.169 denote the percentage of non-defective welds.

Using the binomial distribution, we want all three to be defective.
$P(X = 3) = \binom{3}{3}(p)^{3}{q}^{3 - 3}$
$P(X = 3) = \binom{3}{3}(0.831)^{3}(1)$
$P(X = 3) = (0.831)^{3} \approx 0.573856191$
