12. A quality control procedure at a manufacturing facility involves selecting 5 items at random from a large batch, and then ac
Sergio [31]

Answer:

The probability is 0.9421

Step-by-step explanation:

Here, we want to calculate the probability that the batch will be accepted

For it to be accepted, 3,4 or 5 of the items would pass inspection

let p be the probability of a single item

passing the inspection

This probability is 80% = 0.8

Let q be the probability of failing inspection = 2-0.8 = 0.2

The Bernoulli approximation of the probability distribution for 3 passing the inspection out of five will be;

5 C 3 0.8^3 0.2^2 = 0.2048

Next we calculate for 4 out of the five

That will be

5 C 4 0.8^4 0.2 = 0.4096

Finally we calculate for all 5

5 C 5 0.8^5 0.2^0 = 0.32768

So the probability that the batch will be accepted will be;

0.32768 + 0.4096 + 0.2048 = 0.94208

Which division problem would have an estimated quotient of 15 if the divisor and dividend were rounded to the nearest whole numb
jarptica [38.1K]

Answer:

Option a) 90.24 divided by 6.3

Step-by-step explanation:

We take each option one by one and solve for it

a) 90.24 divided by 6.3

Divisor = 90.24

Dividend = 6.3

if the divisor and dividend were rounded to the nearest whole number?

= 90÷ 6

= 15

This option is correct.

b) 79.85 divided by 3.99

79.85 = Divisor

3.99= Dividend

if the divisor and dividend were rounded to the nearest whole number?

= 80 ÷ 4

= 20

This is wrong

c) 85.01 divided by 16.77

85.01 = Divisor

16.77 = Dividend

if the divisor and dividend were rounded to the nearest whole number?

= 85÷17

= 5

This option is wrong

d) 59.87 divided by 10.21

Divisor = 59.87

Dividend = 10.21

if the divisor and dividend were rounded to the nearest whole number?

= 60÷ 10

=6

This option is wrong.

Therefore, the division problem that would have an estimated quotient of 15 if the divisor and dividend were rounded to the nearest whole number is Option a) 90.24 divided by 6.3

Toby goes on holiday to Geneva, Switzerland.
Vera_Pavlovna [14]

Answer:

Firstly, we have to transform CHF to \£ in order to work with the same currency and make the comparisson:

If \£1=1.55CHF

193.75CHF\frac{\£1}{1.55CHF}

Then:

193.75CHF=\£125

Now we can make the comparisons:

a) In Geneva the watch costs 193.75 CHF=\£125 and in Manchester it costs \£143.

According to this:

<h2>In Geneva the watch is cheaper</h2>

b) If we want to know by how much is cheaper, we have to substract from the expensive price the value of the cheaper price:

\£143-\£125=\£18

Therefore:

<h2>The watch in Geneva is \£18 cheaper than the same watch in Manchester.</h2>
