the annual salaries at a particular company are approximately normally distributed with a mean of $100,000 and a standard deviat
Jobisdone [24]

The annual salaries at a particular company are approximately normally distributed with a mean is 0.42124

Manufacturing job :

Mean (m) = 40,000

Standard deviation (s) = 9000

Sales job :

Mean (m) = 35000

Standard deviation (s) = 9000

Probability of earning more than 45000 if one or the other job is selected;

Obtaining the standardized scores and probability for each :

Z = (x - m) / s

P(x > 45000)

Z = (45000 - 40000) / 9000 = 0.5555

= 0.56

P(Z > 0.56) = 0.28774(Z probability calculator)

For sales

P(x > 45000)

Z = (45000 - 35000) / 9000 = 1.1111111

= 1.11

P(Z > 1.11) = 0.1335 (Z probability calculator)

0.28774 + 0.1335 = 0.42124

On a piece of paper, use a protractor to construct right triangle ABC with AB=3 in. , m∠A=90° , and m∠B=45° .
n200080 [17]

Option A: $A C=3 \ in is true about the triangle.

Explanation:

The measurements of the right triangle ABC is A B=3 \ in , m \angle A=90^{\circ} and \mathrm{m} \angle{B}=45^{\circ}

The image of the triangle having these measurements is attached below:

Option A: $A C=3 \ in

Using Pythagorean theorem, we have,

tan \ 45^{\circ}= \frac{AC}{3}

   1\times 3= AC

         3=AC

Thus, the length of AC is $A C=3 \ in

Therefore, Option A is true about the triangle.

Hence, Option A is the correct answer.

Option B: $B C=3\ in

Using Pythagorean theorem, we have,

cos \ 45^{\circ}=\frac{3}{BC}

     BC=\frac{3}{cos \ 45^{\circ}}

     BC=\frac{3}{0.707}

     BC=4.24

Thus, the length of BC is BC=4.24 \ in

Therefore, Option B is not true about the triangle.

Hence, Option B is not the correct answer.

Option C: $B C=6\ in

Using Pythagorean theorem, we have,

cos \ 45^{\circ}=\frac{3}{BC}

     BC=\frac{3}{cos \ 45^{\circ}}

     BC=\frac{3}{0.707}

     BC=4.24

Thus, the length of BC is BC=4.24 \ in

Therefore, Option C is not true about the triangle.

Hence, Option C is not the correct answer.

Option D: $A C=6\ in

Using Pythagorean theorem, we have,

tan \ 45^{\circ}= \frac{AC}{3}

   1\times 3= AC

         3=AC

Thus, the length of AC is $A C=3 \ in

Therefore, Option D is not true about the triangle.

Hence, Option D is not the correct answer.
