5. Which of the following statements is true?
(a) Two acute angles can be complementary to each other
(b) Two obtuse angles can be complementary to each other
(c) Two right angles can be complementary to each other
(d) One obtuse angle and one acute angle can be complementary to each other​

Answers

Answer 1
A- two acute angles can be complementary

Complementary angles add to 90°, and obtuse angles are defined as being over 90°, so no answer with obtuse would work.
A right angle is 90° exactly, and 2 would add to 180°, so C cannot be right.

an airplane travels 480 miles in 3 hours with the Wind. the return trip against the wind takes 4 hours. what is the wind speed and the speed of the airplane in still air?​

Answers

Answer:

Plane speed: 100  &  Wind:20

Step-by-step explanation:

Plane speed =x mph

wind speed =y mph

against wind 6 hours

with wind 4 hours

Distance against 480 miles distance with 480 miles

t=d/r against wind -

480 / ( x - y )= 6

6 ( x - y ) = 480

6 x - 6 y = 480 ....................1

480 / ( x + y )= 4.00

4.00 ( x + y ) = 480

4.00 x + 4.00 y = 480 ...............2

Multiply (1) by 4

Multiply (2) by 6 24

we get

24.00 x + -24 y = 1920

24.00 x + 24 y = 2880

48 x = 4800

/ 48

x = 100 mph

plug value of x in (1)

6 x -6 y = 480

600 -6 y = 480

-6 y = 480 -600

-6 y = -120 mph

y = 20

Plane speed 100 mph

wind speed 20 mph

A poster is to have a total area of 500 square centimeters. There is a margin around the edges of 4 cm at the top and 8 cm on the bottom and sides where nothing is printed. Express the printed area A in terms of the width w (in centimeters) of the bottom.

Answers

Answer:

A(w) = 692 - 12w - (8000/w)

Step-by-step explanation:

Since it has a total area of 500 cm², it means that;

A = hw

Where;

A is area

h is height

w is width

Thus;

500 = hw

h = 500/w

We are told that There is a margin around the edges of 4 cm at the top and 8 cm on the bottom and sides where nothing is printed.

Thus;

We have height as; (h - 4 - 8) and width as; (w - 8 - 8)

Thus;

Area = (h - 4 - 8) × (w - 8 - 8)

Area = (h - 12) × (w - 16)

We know that h = 500/w

And we want to find the printed area in terms of the width(w)

Thus;

A(w) = ((500/w) - 12) × (w - 16)

A(w) = 500 - 12w - 8000/w + 192

A(w) = 692 - 12w - (8000/w)

Using the area formula, the appropriate expression for the area of the poster is A(w) = - 8000/w - 12w + 692

Total Area = 500 cm²

Area = Length × width

Entire area can be expressed thus :

500 = l × w l = 500 / w

Area with print can be expressed thus :

Length with print = (l - 8 - 4) = (l - 12) cm

Height with print = (w - 2(8)) = (w - 16) cm

Area = (l - 12)(w - 16)

Area = (500/w - 12)(w - 16)

Expressing in terms of width :

A(w) = 500 - 8000/w - 12w + 192

A(w) = - 8000/w - 12w + 692

Hence, the required expression is : A(w) = - 8000/w - 12w + 692

[tex]r=160-12m[/tex]

We can also rearrange it to look like a point-slope equation. Either way works, it's the same equation.

Given here, After sprinting, Emilie has a heart rate of 160. As

she cools down, her heart rate falls by 12 beats therefore, we can form the equation as if the time  is t minutes of cooling down then we can the heartbeat at a given time as y=160-12t

The salaries of pharmacy techs are normally distributed with a mean of $32,000 and a standard deviation of $3,000. If a pharmacy tech is selected at random, what is the probability they make more than $39,000?

Answers

Answer:

The probability is  [tex]P( X > 39000) =0.01[/tex]

Step-by-step explanation:

From the question we are told that

   The mean is  [tex]\mu = \$ 32000[/tex]

    The standard deviation is [tex]\sigma = \$ 3000[/tex]

Generally the probability that they make more than $39,000 is mathematically represented as

         [tex]P( X > 39000) = P( \frac{X - \mu }{\sigma } > \frac{39000 - 32000}{3000} )[/tex]

 [tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

          [tex]P( X > 39000) = P(Z > 2.33 )[/tex]

From the z table  the area under the normal curve to the right corresponding to  2.33  is      

         [tex]P(Z > 2.33 ) = 0.01[/tex]

So

         [tex]P( X > 39000) =0.01[/tex]

     

The probability they make more than $39,000 is 1%

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation\\\\Given \ that:\\\\\mu=32000,\sigma=3000.For\ x>39000:\\\\z=\frac{39000-32000}{3000}=2.33[/tex]

From the normal distribution table:

P(x > 39000) = P(z > 2.33) = 1 - P(z < 2.33) = 1 - 0.9901 = 0.0099 = 1%

Therefore the probability they make more than $39,000 is 1%

An FBI survey shows that about 30% (i.e., 0.3) of all property crimes go solved. Suppose that in New York City 15 such crimes are committed and they are each deemed independent of each other.

a. What is the probability that exactly 3 of these 15 crimes will be solved? b. What is the probability that at most 3 of these 15 crimes will be solved? c. What is the probability that more than 11 of these 15 crimes will be solved?

Answer:

0.17

0.29686

0.000092

Step-by-step explanation:

Given that :

Probability of success (p) = 0.3

Number of cases (n) = 15

1 - p = 1 - 0.3 = 0.7

Usung binomial distribution formula :

a. What is the probability that exactly 3 of these 15 crimes will be solved?

P(x = 3)

Recall:

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

P(x = 3) = 15C3 * 0.3^3 * 0.7^12

P(x = 3) = 455 *

P(x = 3) = 0.17

B.) What is the probability that at most 3 of these 15 crimes will be solved?

P( X ≤ 3) = P(x = 0) + p(x = 1) + p(x = 2) + p(x = 3)

To save computation time, we can using the binomial probability calculator :

P( X ≤ 3) : 0.00474 + 0.03052 + 0.09156 + 0.17004 = 0.29686

c. What is the probability that more than 11 of these 15 crimes will be solved?

P( X > 11) = P(x = 12) + p(x = 13) + p(x = 14) + p(x = 15)

P( X > 11) = 0.000092

151°

Step-by-step explanation:

First, we must identify the geometric figure in the diagram. It has five angles, so it's a pentagon.

It is also important to remember that the sum of all interior angles in a pentagon is 540°. So that means:

5x+2 + 10x-3 + 8x-19 + 13x-31 + 7x-11 = 540

43x-62 = 540

43x = 602

x = 14°

Now, we just plug in value of x into the expression for angle S:

S = 13x-31

The experimental probability of rolling an odd number is 60%, which is 10% more than the theoretical probability.

What is probability?

The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

A special 8-sided die is marked with the numbers 1 to 8.

It is rolled 20 times with these outcomes:

{3 4 5 2 7 1 3 7 2 6 2 1 7 3 6 1 8 3 5 6}

The experimental probability of rolling an odd number is :

⇒ 12/20

⇒ 0.6

The percentage of experimental probability = 0.6 × 100 = 60%

Theoretical probability as:

⇒ 4/8 × 100 = 50%

Difference between experimental and theoretical probability

⇒ 60 - 50 = 10%

Hence, the experimental probability of rolling an odd number is 60%, which is 10% more than the theoretical probability.
