Mathematics
1 answer:
Paraphin [41]2 years ago
3 0

Answer:

AB = 25 units

Step-by-step explanation:

In right triangle ACB, CD\perp AB

Therefore, by geometric mean property:

CD^{2} ={AD\times DB}  \\  \\  {10}^{2}  = AD\times 5 \\  \\ 100 = 5AD \\  \\  AD =  \frac{100}{5}  \\  \\ AD = 20

AB = AD + DB

AB = 20 + 5

AB = 25 units

The local operations manager for the Internal Revenue Service must decide whether to hire one, two, or three temporary tax exami
Helga [31]

Answer:

If she uses the Laplace criterion, the number of new examiners she will decide to hire is:

c. three

Step-by-step explanation:

a) Data:

Number of           Compliance

examiners     Low   Normal   High

One               50        50         50

Two              100        60         20

Three           150        70         -10

b) Outcome Calculations:

Number of                     Compliance

examiners            Low                      Normal                High

One              16.65 (50 *.333)     16.65 (50 *.333)     16.65 (50 *.333) =  50

Two              33.3 (100 *.333)      19.98 (60 *.333)      6.66 (20 *.333)  = 60

Three           49.95 (150 *.333)    23.31 (70 *.333)     -3.33 (-10 *.333) =  70

c) Decision:

Three has the highest payoff condition and is selected.

d) The Laplace criterion assumes that each compliance state is equally likely to happen.  Therefore, it assigns the same weight to each state of compliance.  Since there are three states of compliance, we shall assign each state a weight of 0.333.  The number of examiners that have the highest payoff condition is three, and therefore, the number "three" is selected.

Pi High School ordered 40 science books. The next week, the school ordered 30 algebra books. The bill for the first order was $3
maria [59]

Answer:

Each algebra book costs $60.

Step-by-step explanation:

A=bill for algebra books; S=bill for science books=A+$360

S+A=$3960 Substitute for S

A+$360+A=$3960 Subtract $360 from each side.

2A=$3600 Divide each side by 2.

A=$1800 The order for 30 algebra books cost $1800.

Individual book=A/30

individual book=$1800/30=$60 ANSWER: Each algebra book cost $60.

an aircraft carrier leads port heading due west at 28 knots. A helicopter is 175 nautical miles from the carrier at an angle of
emmainna [20.7K]
Let’s say it takes time t hours for the interception.
In that time the carrier travels 28t nm west and the helicopter 130t nm.
Now we use the sine rule to find the angle x which lies between the distance 175 and 130t.
sin(x)/28t=sin35/130t. So sin(x)=28sin35/130=14sin35/65=0.1235 and x=7.0964 degrees.
Therefore the helicopter should use a bearing of 35+7.0964=42.0964 degrees north of east or 47.9 degrees east of north approx.
