About 10% off since you divide 100 by 12 and times it by 13.2 so the percent comes to be 109.9 to you round up amd its 10 percent over

Brianna has 4 pink bracelets. One third of all her bracelets are pink . How many bracelets does Brianna have ?

Korvikt [17]

Answer:

Total number of bracelets Brianna have are 12 .

Step-by-step explanation:

Let us assume that the total numbers of the bracelets be x .

As given

Brianna has 4 pink bracelets.

One third of all her bracelets are pink .

Than the equation becomes

$\frac{1\times x}{3} = 4$

Simplify the above

x = 4 × 3

x = 12

Therefore the total number of bracelets Brianna have are 12 .

Human visual inspection of solder joints on printed circuit boards can be very subjective. Part of the problem stems from the nu

olga_2 [115]

Answer:

a

The probability that the selected joint was judged to be defective by neither of the two inspectors is $P(A' n B' ) = 0.8855$

b

The probability that the selected joint was judged to be defective by inspector B but not by inspector A is $P(A' n B) =0.0403$

Step-by-step explanation:

From the question we are told that

The sample size is $n_s = 10000$

The number of outcome for inspector A is $n__{A}} = 742$

The number of outcome for inspector B is $n__{B}} = 745$

The number of joints judged defective by both inspector is $n(A u B) = 1145$

The the probability that the selected joint was judged to be defective by neither of the two inspectors is mathematically represented as

$P(A' n B' ) = 1 - P(A u B)$

Now

$P(A\ u \ B) = \frac{n(Au B)}{n_s }$

substituting values

$P(A\ u \ B) = \frac{1145}{ 10 000 }$

So

$P(A' n B' ) = 1 - \frac{1145}{10 000}$

$P(A' n B' ) = 0.8855$

the probability that the selected joint was judged to be defective by inspector B but not by inspector A is mathematically represented as

$P(A' n B) = P(A \ u \ B) -P(A)$

Now

$P(A) = \frac{n__{A}}{n_s}$

substituting values

$P(A) = \frac{742}{10 000}$

So

$P(A' n B) = \frac{1145}{10 000} - \frac{742}{10 000}$

$P(A' n B) =0.0403$
