Igoryamba

Answer:

0.4629

Step-by-step explanation:

Using the binomial probability relation :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

Number of trials, n = 25

Probability of having defective tablet greater than 3 p(x ≥ 3) ;

p = 0.10 ;

1 - p = 1 - 0.10 = 0.90

P(x ≥ 3) = P(x = 3) + p(x = 4) +.... + p(x = 25)

Using a binomial probability calculator :

P(x ≥ 3) = 0.4629

Therefore, the probability that shipment would be sent back to the vendor is 0.4629

Write 77.5% as a fraction or mixed number in simplest form.
Delicious77 [7]

Answer:

The answer is  77\frac{1}{2} .

Step-by-step explanation:

Given:

77.5%.

Now, to write as a fraction or mixed number in simplest form.

77.5%

So, we divide by 10 by removing decimal as decimal is at tenth place.

= \frac{775}{10}

So, simplifying it:

=\frac{155}{2}

Now, we change into mixed fraction:

=77\frac{1}{2}

Therefore, the answer is 77\frac{1}{2} .

BabaBlast [244]
<span>We need to use the distance formula for this problem. d = sqrt[(x2 - x1)^2 + (y2 - y1)^2] We need to find these values. d = (52)^2 + (30)^2 Thus, these ships are approximately sqrt(3604) = about 60 miles apart.</span>
