Step-by-step explanation:

I can only answer part 2 of your question, "If we multiply two positive numbers, is the result positive or negative?". if you multiply 2 positive numbers your answer would be positive.

If we multiply two positive numbers, then the result is also positive.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that If a car is traveling east when it passes the camera, then;

the position be positive 60 seconds after it passes the camera.

Therefore, If we multiply two positive numbers, then the result is also positive.

Answer:

The angle of elevation from the base to the top of the mountain is 30°.

Step-by-step explanation:

Given: Vertical height of mountain is 650 feet and the distance from the top of the mountain to the base is 1300 feet.

To find: The angle of elevation from the base to the top of the mountain.

Let AB be the height of mountain and BC be the base.

Then, according to question, AB=650 feet and AC=1300 feet.

Let ∠ACB=[tex]\Theta[/tex].

Then, in ΔABC,

[tex]sin\Theta=\frac{AB}{AC}[/tex]

⇒[tex]sin\Theta=\frac{650}{1300}[/tex]

⇒[tex]sin\Theta=\frac{1}{2}[/tex]

⇒[tex]\Theta=30[/tex]°

Hence, the angle of elevation from the base to the top of the mountain is 30°.

the answer is 162

Answer: $65; $35+r•2

Step-by-step explanation:

So if every ride Brayden goes on costs $2 and he rides 15 rides, 2•15= $30 from rides alone. Then you add the $35 from admission to that number to get $65. This works for any amount of rides, just change the number to how many rides he goes on and use the same formula, 35+r•2 where r equals the number of rides ridden.

Step-by-step explanation:

The required estimate of the area in square inches of the stove top that does not include the area of the burners is 415 square inches.

Surface area is defined as the measure of a region or surface is called as surface area.

The best estimate of the area of the stovetop that does not include the area of the burners can be obtained by subtracting the total area of the four burners from the total area of the stovetop.

The total area of the stove top is given by the product of its length and width:

Length = 24 inches

Width = 22 inches

Area = Length × Width = 24 × 22 = 528 square inches

The area of each burner is given by the formula for the area of a circle:

= π × (diameter/2)²,
where π is approximately equal to 3.14

Since the diameter of each burner is 6 inches, the radius of each burner is 6/2 = 3 inches.

Area of one burner = Pi × (3)² = 3.14 × 9 = 28.26 square inches

The total area of the four burners is 4 × 28.26 = 113 square

The area of the stove top = 528 - 113
                                       = 415 square inches.

Thus, the required estimate of the area in square inches of the stove top that does not include the area of the burners is 415 square inches.

Step-by-step explanation:

132 is what percent of 880? = 15.

Answer:

The answer is below

Step-by-step explanation:

For a normal distributed population with a mean (μ), and a standard deviation (σ), if a sample size of n is selected from the population, the mean of the sample ([tex]\mu_x[/tex]) =  μ and the standard deviation of the sample ([tex]\sigma_x[/tex]) = [tex]\frac{\sigma }{\sqrt{n} }[/tex]

Let the normal distribution population have a standard deviation of σ. If the standard deviation is to be decreased by half, the sample size (n) needed is:

[tex]Using:\\\\\sigma_x=\frac{\sigma}{\sqrt{n} } \\\\but\ \sigma_x=\frac{\sigma}{2}\\\\Hence:\\\\ \frac{\sigma}{2}=\frac{\sigma}{\sqrt{n} }\\\\Divide\ through\ by \ \sigma\ to\ get:\\\\ \frac{1}{2}=\frac{1}{\sqrt{n} }\\\\\sqrt{n}=2\\\\square\ both\ sides:\\\\(\sqrt{n} )^2=2^2\\\\n=4\\\\[/tex]

To decrease the standard deviation of the sampling distribution by half we need a sample size of 4

Answer:

2, (x+13)/6, -7

Step-by-step explanation:

The -1 bit means do it backwards, so look the for the output of the function with the value given.

In g, when we put in 2 we get 9 out, so g^-1(9) is 2.

For the second one we need to rearrange it to get x = something.

h(x) + 13 = 6x

x = (h(x) + 13)/6

Then replace the h(x) with x and the x with h^-1(x) to get

h^-1(x) = (x + 13)/6

The last one is a trick. Note that h and h^-1 are opposites. If we do something then do the opposite of it, we haven't done anything at all! So the number stays the same.

Number of flips it would take for tail to appear first :

Treatting the question as a geometric function :

Using the relation :

1 / p

Expected number of flips until first tail :

1 / P = 1/ 0.64 = 1.5625

E(x) = expected number of flips until first tail = 1.563
