Answer:

P(outcome) - P(-outcome) = 1

Step-by-step explanation:

Given

Let the complementary probabilities be represented with P(outcome) and P(-outcome)

Required

Determine which of the options do not show complementary probabilities

In probability, complementary probability sums up to 1

i.e.

[tex]P(outcome) + P(-outcome) = 1[/tex]

Hence option C is correct

Make P(outcome) the subject of formula

[tex]P(outcome) = 1 - P(-outcome)[/tex]

Hence, option A is correct

Make P(-outcome) the subject of formula

[tex]P(-outcome) = 1 - P(outcome)[/tex]

Hence, option D is correct

So, from the list of given options,

[tex]P(outcome) - P(-outcome) = 1[/tex] is incorrect

Answer:

The probability is [tex]P(X > 25 ) = 1.667[/tex]

Step-by-step explanation:

From the question we are told that

    The  maximum wait is  [tex]b = 30 \ minutes[/tex]

      The  minimum wait would be  [tex]a = 0\ minutes[/tex]

Generally the probability that you will wait more than 25 minutes for a bus is mathematically represented as

   [tex]P(X > 25 )[/tex]

Now given that the time a person waits is uniformly distributed and that the maximum is  30 then we can evaluate the above probability as

    [tex]P(X > 25 ) = P(25 < X < 30 ) = \frac{30 - 25}{30 - 0}[/tex]

     [tex]P(X > 25 ) = 1.667[/tex]

Answer:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

Answer:

Option b (factor) is the correct choice.

Step-by-step explanation:

ANOVA would be used to assess whenever there were other statistically representative variations seen between results of two or even more individual (totally unconnected) categories.

Two different kinds of independent variables exist such as:

If the explanatory variables are such an effective variable otherwise we modify the argument of the variable to test its effect on something like a specific parameter.

Certain solutions don't apply to the specified scenario. So choice B was its perfect method for that.

Answer:

the area is: 90 square inches

Step-by-step explanation:

Since you use the same amount of material to create the rectangle, that means that the area of a parallelogram has the same formula as the area of a rectangle. That is:

Area of  parallelogram = base x height

Answer:

y = 3x - 9

Step-by-step explanation:

First, find the slope using rise/run (y2 - y1) / (x2 - x1)

Plug in the points:

(36 - 21) / (15 - 10)

15/5

= 3

Next, plug the slope and a point into the equation y = mx + b to find b (y-int)

y = mx + b

21 = 3(10) + b

21 = 30 + b

-9 = b

Then, plug this into the equation, as well as the slope:

y = 3x - 9

Answer:

14.9 miles

Step-by-step explanation:

If the road was created, the 3 different roads would form a right triangle where the new road would be the hypotenuse and the other 2 roads would be the legs.

We can use the pythagorean theorem to find the length of the hypotenuse, or the new road:

a² + b² = c²

14² + 5² = c²

221 = c²

14.9 = c

= 14.9 miles

Answer:

The ratio is 13:9

Step-by-step explanation:

Since the rest of the flowers in the vase are daisies, subtract the 4 roses from the 13 flowers. 13 - 4 = 9

There will be 9 daisies in the vase in total. Then they are asking for you to put the ratio of the total flowers to the daisies.

Total Flower = 13

Daisies = 9

The ratio would be 13 to 9.

The ratio of all flowers in the vase to daises is [tex]13:9[/tex]

Given the following data:

To determine the ratio of all flowers in the vase to daises:

First of all, we would solve for the number of daisies in the vase of flowers.

[tex]Number\;of\;daisies = 13-4[/tex]

Number of daisies = 9 daisies.

Now, we can find the ratio of all flowers in the vase to daises:

[tex]Ratio = F:D\\\\Ratio = 13:9[/tex]

This question is incomplete, the complete question is;

A bank is designing a new branch office and needs to determine how much driveway space to allow for cars waiting for drive-up teller service.

The drive-up service will have three tellers and a single waiting line. At another branch of the bank in a similar setting, the average service time for drive-up tellers is four minutes per customer, and average arrival rate is 36 customers per hour. It is expected that the new bank will have similar characteristics.

How many spaces should be provided to have a 96 percent probability of accommodating all of the waiting cars?

Answer:

Eleven (11) spaces should be provided to have a 96 percent probability of accommodating all of the waiting cars

Step-by-step explanation:

Given that:

the average service time for drive-up tellers is four (4) minutes per customer at each branch

Average number of customers per hour is 36

Therefore for 36 customers,

the branch can give ( 36 / 4 ) = 9, mins each customer

from the question, there is a probability of 96%

so we will calculate on the 9 as mentioned above

96% of 9 = 0.96

0.96 × 9= 8.64

If there are 3 tellers in a single line- , then

8.64 + 3 = 11.64 approximately 11

Therefore Eleven (11) spaces should be provided to have a 96 percent probability of accommodating all of the waiting cars

Answer:

y-9=4/3(x-2)

Step-by-step explanation:

First, find your slope:

The formula for finding slope is [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].

Our coordinate point for our x₁ and y₁ values will be (2,9) and our coordinate point for our x₂ and y₂ values will be (-1,5).  Now, let's plug those into our formula:

[tex]m=\frac{5-9}{-1-2}=\frac{-4}{-3}=\frac{4}{3}[/tex]

Your slope is 4/3.

Next, plug in your x₁ and y₁ values in for point-slope form.  The equation in variable form is "y-y₁=m(x-x₁)".  So, plugging in our point (2,9) for x₁ and y₁, we get:

y-9=4/3(x-2)

Answer:

-28

Step-by-step explanation:

-7 (2-1)-21

-7 (2-1)=-7

-7-21=-28

Answer:

a) The set of real numbers is the union of the set of Irrational numbers and the set of rational numbers.

b) Real numbers have a lot of properties, one example is that they are closed under a lot of operations, like addition or multiplication.

This means that if we have two real numbers A and B:

A + B is also a real number.

A*B is also a real number.

c) A good way to learn Algebra (or math in general) is:

First, read the textbook, have a general idea of the complete topic, if you don't understand something, keep reading, just take note of all the things you don't understand.

Second, ask the things that you do not fully understand, not shame in it, math has a lot of complex relations that sometimes can be really hard to understand, and there are a lot of cases (at least for me) where one can think that understands very well a topic, but it is wrong, so in order to avoid this, ask everything you can.

Third, do a LOT of exercises, the only way in which you can learn to use your equations and relations is applying them in math problems, and it will also help you to understand the meaning of those equations in a more profound way.

Answer:

x = 4/3

Step-by-step explanation:

15 - 5x = 6x + 3 - 2x

In this kind of equation, we try to seperate the x's and the numbers.

So we add 5x to both sides and subtract 3 from both sides to seperate these values

15 - 3 - 5x + 5x = 6x + 3 - 3 - 2x + 5x

=> 12 = 9x

=> 12/9 = x

=> 4/3 = x

=> x = 4/3

To check, we can plug this in.

15 - 5(4/3) = 6(4/3) + 3 - 2(4/3)

15 - 20/3 = 24/3 + 3 - 8/3

45/3 - 20/3 = 24/3 + 9/3 - 8/3

25/3 = 25/3

So our answer works.

Answer:

P = 8000*(n -c)

Step-by-step explanation:

Profit is the difference between cost and selling price.

For 8000 cars produced per month, the profit will be:

f(x) = g(x)

-3x+4 = g(x) ... f(x) replaced with -3x+4

-3x+4 = 2 .... g(x) replaced with 2

-3x+4-4 = 2-4 .... subtract 4 from both sides

-3x = -2

-3x/(-3) = -2/(-3) .... divide both sides by -3

x = 2/3

Answer:

C .128 ft²

Step-by-step explanation:

net with 4 rectangles and 2 squares.

The rectangles measure 6 feet by 4

Area of the rectangle=6*4

Area of the rectangle= 24.ft²

Total area of the rectangle= 4*24.

Total area of the rectangle= 96 ft²

the squares have side lengths of 4 feet.

Area of tge square= 4²

Area of the square= 16ft²

Total area of the square= 16*2

Total area of the square= 32 ft²

Total area of the cardboard needed

= Area of square + Are of rectangle

= 32+96

= 128 ft²

Answer: The value of the hypotenuse is 61.

Step-by-step explanation:

So we are given a triangle with two known sides; two legs with values of 11 and 60. We have to use the Pythagorean Theorem to find the value of the hypotenuse.

The Pythagorean Theorem states that, "the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides".

This means that:

a^2 + b^2 = c^2

leg^2 + leg^2 = hypotenuse^2

So just by looking at that, we know that we can just substitute the values in:

11^2 + 60^2 = x^2

121 + 3600 = 3721

sqrt of 3721 = 61

So the hypotenuse value is 61.
