The probability of a quarter, a dime, and a penny all landing on heads is found by multiplying the individual probabilities for each coin, resulting in a 12.5% likelihood.

The question asks about the probability of a quarter, a dime, and a penny all landing on heads when accidentally dropped. To determine this, we assume each coin has a 50-50 chance of landing on heads or tails, i.e., the probability of heads is 0.5 for each coin toss. Since each coin is independent of the others, we apply the product rule of probability for independent events.

Therefore, the probability of all three coins landing on heads is:
Probability(Quarter on heads) × Probability(Dime on heads) × Probability(Penny on heads) = 0.5 × 0.5 × 0.5 = 0.125 or 12.5%.

This represents an application of the product rule, as each coin toss is an independent event and the final probability is the product of the individual probabilities.

Answer:

A right angled triangle is a triangle where one of the internal angles is 90°.

Consider the general right angle triangle, in figure 1 below, with angle β and sides labeled as shown below

Right-Angle-Triangle

The sides are labeled with respect to the angle β, so that the nearest side is called the adjacent side, the side that is directly opposite is called the opposite side while the longest side is called the hypotenuse.

Therefore, given any angle in a triangle, it should be easy to identify the adjacent, the opposite side and the hypotenuse.

Example

Reference to the figure below.

Example1

1. Identify the right angle triangles in the above diagram.

Solution: A right angled triangle is a triangle where one of the internal angles is 90°. Such triangles are ABC, ABN, DAC and DNC.

2. Identify the adjacent sides to angles θ, α, β and µ.

Solution:

   Angle θ is in triangle DAC. The angle is nearer to line AC hence, it is the adjacent line.

   Angle α is in triangle ABN. The angle is nearer to line AB hence, it is the adjacent line.

   Angle β is in triangle DNC. The angle is nearer to line DC hence, it is the adjacent line.

   Angle µ is in triangle ABC. The angle is nearer to line AB hence, it is the adjacent line.

3. Identify the opposite sides to angles θ, α, β and µ.

Solution:

   Angle θ is in triangle DAC. The angle is opposite to line DC hence, it is the opposite line.

   Angle α is in triangle ABN. The angle is opposite to line AN hence, it is the opposite line.

   Angle β is in triangle DNC. The angle is opposite to line CN hence, it is the opposite line.

   Angle µ is in triangle ABC. The angle is opposite to line AC hence, it is the opposite line.

4. Identify hypotenuse with respect to angles θ, α, β and µ.

Solution:

   Angle θ is in triangle DAC. The longest side in that angle triangle is AD hence, it is the hypotenuse.

   Angle α is in triangle ABN. The longest side in that angle triangle is NB hence, it is the hypotenuse.

   Angle β is in triangle DNC. The longest side in that angle triangle is DN hence, it is the hypotenuse.

   Angle µ is in triangle ABC. The longest side in that angle triangle is CB hence, it is the hypotenuse.

Step-by-step explanation:

The area of a square is equal to the side squared.

[tex]s^{2} = A[/tex]

We can plug in 24 for A and then take the square root of each side to

find s.

[tex]s^{2} = 24[/tex]

[tex]s = \sqrt{24}[/tex]

We can simplify √24.

The prime factorization of 24 is 2 x 2 x 2 x 3.

Since we have 2 x 2 inside the radical we can simplify to have 2

outside the racial.

[tex]\sqrt{24} = \sqrt{4*6} = 2 \sqrt{6}[/tex]

We can then use a calculator to find an approximate decimal value

To determine the sign of the sum of two numbers, we need to consider the signs of the individual numbers (A and B) involved in the sum.

1. If both numbers are positive, their sum is also positive.
2. If both numbers are negative, their sum is also negative.
3. If one number is positive and the other is negative:
  - If the positive number has a greater absolute value than the negative number, the sum is positive.
  - If the negative number has a greater absolute value than the positive number, the sum is negative.
  - If both numbers have the same absolute value, the sum is zero.

The question only presents the expression "B + A" without any information regarding the values or signs of A and B. Therefore, without additional information, it's impossible to determine the sign of their sum. The sum could be positive, negative, or zero depending on the values (and their respective signs) of A and B. Consequently, we cannot choose any of the options above with certainty.

For a complete answer, we would need more details about the values of A and B.

Answer: ( - ∞ , 10 ] , { y| y ≤ 10 }

Step-by-step explanation: You have to find the domain by finding where the function is defined. The range is the set of the values that correspond with the domain.

The range of the function f(x) = 10 - x^2 is all real numbers less than or equal to 10.

To find the range of the function f(x) = 10 - x^2, we need to consider the maximum and minimum values that f(x) can take. The parabola opens downwards since the coefficient of x^2 is negative, which means it has a maximum value and no minimum value. The vertex of this parabola occurs at x = 0, which gives us the maximum value of f(0) = 10. Therefore, the range of f(x) is all real numbers less than or equal to 10, which can be expressed as f(x) ≤ 10 or in interval notation, \\[10, -∞).

Answer: 701

Answer:

(x-6)^2 + (y-2)^2 = 64

Step-by-step explanation:

We can write the equation of circle as

(x-h)^2 + (y-k)^2 = r^2

Where (h,k) is the center and r is the radius

(x-6)^2 + (y-2)^2 = 8^2

(x-6)^2 + (y-2)^2 = 64

Circle equation: (x - h)² + (y - k)² = r²

The center is (h, k) and the radius is r.

(x - 6)² + (y - 2)² = 8²

(x - 6)² + (y - 2)² = 64

Final answer:

The growth factor of Star City is calculated by converting the rate of increase to a decimal and adding it to 1, resulting in a growth factor of 1.023.

Explanation:

The growth factor of Star City with an annual rate of increase of about 2.3% can be calculated as follows:

Identify the percentage of growth as a decimal by dividing the percentage by 100, which would be 2.3/100 = 0.023.

Add this decimal to 1 to find the growth factor: 1 + 0.023 = 1.023.

Therefore, the growth factor of Star City is 1.023.

The value of x in the expression given is 72.

From the equation given, we can calculate the value of x thus :

cross multiply

9(366 + x) = 6(585 + x)

3294 + 9x = 3510 + 6x

9x - 6x = 3510 - 3294

3x = 216

x = 216/3

x = 72

Hence, the value of x is 72

Step-by-step explanation:

You need to get everything on one side to have a quadratic equation:

x^2+6x-4 -(3x+6) = x^2+3x-10

All factors of 10 are 1*10 and 2*5.

5-2 = 3 and 5*-2 = -10

Factoring x^2+3x-10 gives us (x-2)(x+5)

x=2

x=-5

Answer:

x=-5      x=2

Step-by-step explanation:

x^2+ 6x - 4 = 3x + 6

Subtract 3x from each side

x^2+ 6x-3x - 4 = 3x-3x + 6

x^2+ 3x - 4 =  6

Subtract 6 from each side

x^2+ 3x - 4-6 = 6 - 6

x^2 +3x -10 =0

Factor

What 2 numbers multiply to -10 and add to 3

5*-2 =-10

5+-2 = 3

(x+5) (x-2) =0

Using the zero product property

x+5 =0   x-2 =0

x=-5      x=2

Answer:

y-intercept=32

Step-by-step explanation:

You can find the y-intercept using the slope-intercept form:

[tex]y=mx+b[/tex]

M is the slope and b is the y-intercept. To find the y-intercept, first find the slope. Take two of the points from the table (x,y) and use the slope formula:

[tex](64,12)(48,17)\\\\\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =\frac{rise}{run}[/tex]

Rise over run is the change in the y-axis over the change in the x-axis:

[tex](64(x_{1}),12(y_{1}))\\(48(x_{2}),17(y_{2}))[/tex]

[tex]\frac{17-12}{48-64}= \frac{5}{-16}=-\frac{5}{16}[/tex]

Now that we have the slope, insert into the equation:

[tex]y=-\frac{5}{16} x+b[/tex]

Take a point from the table and insert into the x and y values:

[tex](64_{x},12_{y})\\\\12=-\frac{5}{16}(64)+b[/tex]

Solve for b. Simplify parentheses:

[tex]-\frac{5}{16}*\frac{64}{1}=-\frac{320}{16}=-20[/tex]

[tex]12=-20+b[/tex]

Add 20 to both sides to isolate b:

[tex]20+12=-20+20+b\\32=b\\b=32[/tex]

If b equals 32, then the y-intercept is 32.**

Finito.

**The y-intercept is where x is equal to 0 (0,32)
