Heather flipped a coin five times, and each time it came up heads. Heather flips the coin one more time. Which is the theoretical probability that it will come up tails?

Answer:

[tex] {12}^{ - 11} [/tex]

Step-by-step explanation:

The expression to be simplified is

[tex] {12}^{ - 6} \times {12}^{ - 5} [/tex]

We can see that the expression involves the idea of indices.Thus,we need to consider one of the laws of indices when dealing with the expression.

One of the laws of indices states that,

[tex] {a}^{m} \times{a}^{n} = {a}^{m + n} [/tex]

This means that when multiplying indices and the bases are equal, you repeat one of the bases and add the exponents.

This implies that

[tex] {12}^{ - 6} \times {12}^{ - 5} = {12}^{ (- 6 - 5)} [/tex]

Simplifying the exponent we obtain

[tex] = {12}^{ - 11} [/tex]

Answer:

(2,1)

(-4,13)

Step-by-step explanation:

we have

[tex]2x+y=5[/tex] -----> equation A

[tex]3y=15-6x[/tex] ----> equation B

Multiply the equation A by 3 both sides

[tex]3(2x+y)=3(5)[/tex]

[tex]6x+3y=15[/tex]

isolate the variable 3y

[tex]3y=15-6x[/tex] -----> equation C

equation B and equation C are equal

That means -----> is the same line

so

The system has infinity solutions

Answer:

p = 3n + 2

Step-by-step explanation:

let n be the number of shapes and p the perimeter

We can construct the following table

n : 1    2    3

p : 5   8    11

The differences in p are constant

8 - 5 = 11 - 8 = 3

Thus p = 3n + ?

n = 1 → 3(1) + ? = 5 ⇒ 3 + ? = 5 ⇒ ? = 2

n = 2 → 3(2) + ? = 8 ⇒ 6 + ? = 8 ⇒ ? = 2

n = 3 → 3(3) + ? = 11 ⇒ 9 + ? = 11 ⇒ ? = 2

We require to add 2 to 3n

Thus

p = 3n + 2

The answer should be about 36,491,112‬

Answer:

[tex]minor\ arc\ BD=100^o[/tex]

Step-by-step explanation:

The picture of the question in the attached figure

we know that

A circumscribed angle is the angle made by two intersecting tangent lines to a circle

so

In this problem

BC and CD are tangents to the circle

BC=CD ----> by the Two Tangent Theorem

That means

Triangle ABC and Triangle ADC are congruent

so

[tex]m\angle BAC=m\angle DAC[/tex]

Find the measure of angle BAC

In the right triangle ABC

[tex]m\angle BAC+m\angle BCA=90^o[/tex]

substitute given value

[tex]m\angle BAC+40^o=90^o[/tex]

[tex]m\angle BAC=90^o-40^o=50^o[/tex]

Find the measure of angle BAD

[tex]m\angle BAD=2m\angle BAC[/tex]

[tex]m\angle BAD=2(50^o)=100^o[/tex]

Find the measure of minor arc BD

we know that

[tex]minor\ arc\ BD=m\angle BAD[/tex] -----> by central angle

therefore

[tex]minor\ arc\ BD=100^o[/tex]

Final answer:

The measure of the minor arc BD is d. 80°, because it is twice the measure of the inscribed angle BCA, which is 40°.

Explanation:

When we are looking for the measure of a minor arc in a circle, and we know the measure of the inscribed angle that subtends that arc, we can find the measure of the arc by understanding that the inscribed angle is half the measure of the arc it cuts from the circle. Given that angle BCA measures 40°, and assuming BCD is an inscribed angle that subtends the arc BD, we can deduce that the minor arc BD is actually twice the measure of the inscribed angle BCA.

Therefore, to find the measure of minor arc BD, we double the measure of angle BCA:

Measure of minor arc BD = 2 × measure of angle BCA
Measure of minor arc BD = 2 × 40°
Measure of minor arc BD = 80° (d.)

The slope-intercept form is [tex]y=\frac{1}{2} x+5[/tex].

Solution:

Given data:

Slope of the line, m = [tex]\frac{1}{2}[/tex].

Point on the line = (–2, 4)

Here [tex]x_1=-2, y_1=4[/tex]

Let us find the slope-intercept form of the line using point-slope formula.

Point-slope formula:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]$y-4=\frac{1}{2} (x-(-2))[/tex]

[tex]$y-4=\frac{1}{2} (x+2)[/tex]

[tex]$y-4=\frac{1}{2} x+1[/tex]

Add 4 on both sides of the equation.

[tex]$y=\frac{1}{2} x+5[/tex]

Hence the slope-intercept form is [tex]y=\frac{1}{2} x+5[/tex].

Step-by-step explanation:

if you see the number the line is divided into 6 or to get from 0 to 1 or 2 to 3 it takes 6 space that means the fraction should n/6.

n= a number

2 5/6 that means that there is 2 wholes or 2 6/6

6/6= 1

it is easy to plot 2 5/6 because it is already 5/6, you plot it right on the line that is before 3 or 5 spaces after 2.

1 2/3 is the same as 1 4/6

there is 1 whole or one 6/6. now it is easy you plot it on the line that is 4 spaces away from 1.

Plotted the points on the line. Please see attached.

Answer:   D) (x + 3)² + (y + 5)²  = 16

Step-by-step explanation:

The equation of a circle is: (x - h)² + (y - k)² = r²    

where (h, k) = center   and    r = radius

Given: (h, k) = (-3, -5)  r = 4

Equation: (x - (-3))² + (y - (-5))² = 4²

                 (x + 3)²  +  (y + 5)²  = 16

Using the cost equation C = $25 + ($1.50 x M), we solve for the greatest number of miles Kelly can travel with an $80 budget, which is 36 miles after rounding down to the nearest whole number.

To determine the greatest number of miles Kelly can travel, we use the equation provided by the truck rental company. The total cost of renting a truck is composed of a one-time fee and a per-mile charge. To begin, we subtract the one-time fee from the total budget to find out how much money is left for the per-mile charges.

The equation representing the total cost (C) for the miles (M) driven is:

C = $25 + ($1.50 × M)

Kelly has $80 to spend, so we set the total cost equal to $80:

$80 = $25 + ($1.50 × M)

Now, we solve for M:

$55 = $1.50 × M

M = $55 / $1.50

M = 36.67

Since Kelly cannot travel a fraction of a mile, we round down to the nearest whole number. The greatest number of miles Kelly can travel is 36 miles.

Answer:

The multiplication property of equality states that if two values a and b are equal when you multiply each by the same value c, the products are equal.

Step-by-step explanation:

Multiplication property of equality:

So, if

[tex]a = b[/tex]

Then, we can write by multiplication property of equality

[tex]a=b\\\Rightarrow a\times c = b \times c\\\Rightarrow ac = bc[/tex]

Thus, the correct answer is

The multiplication property of equality states that if two values a and b are equal when you multiply each by the same value c, the products are equal.

Final answer:

The statement in question highlights the equality property of multiplication, which states that if two values are equal, their products with a same multiplier are also equal. This principle is fundamental in mathematics, particularly in algebra, where it underpins the manipulation and understanding of equations.

Explanation:

The statement "if two values a and b are equal when you multiply each by the same value c, the products are equal" refers to the basic principle of the equality property of multiplication in mathematics. This property underlines that if a = b, then a × c = b × c. This fundamental concept is crucial for understanding algebraic expressions and equations, where the manipulation of variables and constants is based on such properties.

For example, if we assert that 3 (number a) and 3 (number b) are equal and we choose to multiply both by 2 (number c), the resulting products, 6 and 6, are indeed equal. This example clearly illustrates how the equality of products remains consistent regardless of the multiplier, as long as the initial quantities are equal.

This principle is foundational in mathematics and serves as a cornerstone for solving equations, thereby reinforcing the understanding that equality is maintained through operations of multiplication by a constant.

The largest radius for the swimming pool is 15.1 feet

Step-by-step explanation:

Step 1:

Circumference of the circular swimming pool built by Dan  = 95 feet

We need to determine the largest radius for the pool.

Step 2 :

Circle's circumference  is given by 2πr

Where r represents the radius

This shows that the radius is in direct proportion to the circumference. Hence the radius corresponding to the maximum circumference will be the largest possible radius

So we have 2πr = 95

=> r = [tex]\frac{95}{2\pi }[/tex]  

=> r =   [tex]\frac{95}{2}[/tex] × [tex]\frac{7}{22 }[/tex]  where [tex]\pi = \frac{22}{7}[/tex]

=> r = 15.1 feet (rounded off to tenth of a foot)

Step 3 :

The largest radius for the swimming pool is 15.1 feet

Final answer:

the largest radius possible for the pool, to ensure the circumference does not exceed 95 feet, is 15.1 feet.

Explanation:

Calculating the Largest Radius for a Swimming Pool

To find the largest possible radius for Dan's circular swimming pool with a circumference of no more than 95 feet, we will use the formula for the circumference of a circle, which is C = 2πr.

We need to solve for r (radius) when C ≤ 95 feet.

Setting up the equation:

Therefore, the largest radius possible for the pool, to ensure the circumference does not exceed 95 feet, is 15.1 feet.

Answer: They will travel about 131.18 yards.

Step-by-step explanation:

Given : A football field is 120 yards long by 53 yards wide.

We know that a football field is rectangular in shape.

Each interior angle in a rectangle is a right angle.

Then, by Pythagoras theorem, we have

(Diagonal)² = (Length)² + (Width)²

If a player runs diagonally from one corner to the opposite corner, then the length of the diagonal is given by :-

[tex](\text{Diagonal})=\sqrt{(120)^2+(53)^2}\\\\\Rightarrow\ (\text{Diagonal})=\sqrt{14400+2809}\\\\\Rightarrow\ (\text{Diagonal})=\sqrt{17209}\\\\\Rightarrow\ (\text{Diagonal})=131.183078177\approx131.18\text{ yards}[/tex]

Hence, they will travel about 131.18 yards.

Final answer:

The distance a player would travel running diagonally across a football field that is 120 yards long and 53 yards wide is approximately 131.183 yards.

Explanation:

The student asked about the distance a player would travel if they ran diagonally from one corner to the opposite corner of a football field that is 120 yards long and 53 yards wide.

To solve this, we need to apply the Pythagorean theorem in which the length and width of the football field will be the legs of the right triangle and the diagonal the player runs will be the hypotenuse.

The formula for the Pythagorean theorem is a² + b² = c², where a and b are the lengths of the legs and c is the length of the hypotenuse.

Therefore, the calculation will be as follows:

(120 yd)² + (53 yd)² = c².

Simplifying,

14400 yd² + 2809 yd² = c².

Adding these together gives us 17209 yd², and taking the square root of that gives us the length of the diagonal, which is the distance the player will travel.

Thus, c = √17209 yd2 ≈ 131.183 yards.

B. False

There are cases where this is not true, but if you want to prove that, you'll need to know what f and g are. For example, if f(x) = x - 3 and g(x) = x2, then f(g(x)) is not equal to g(f(x)) because

f(g(x)) = x2 - 3 and g(f(x)) = (x - 3)2. Those 2 functions are not the same because f(g(0)) = -3 ≠ 9 = g(f(0)).

The polynomial 1 - bx - x + b can be factored by rearranging the terms to (1 + b) - x(1 + b), allowing us to factor out 1 + b, resulting in the factored form (1 + b)(1 - x).

The polynomial in question, 1 \\u2212 bx \\u2212 x + b, can be factored by rearranging and grouping terms. Indeed, the suggestion to factor out at least one x from all terms that contain it can be helpful in some cases, for example, ax^2+bx+c. However, for the polynomial given, we need to rearrange the terms to (1 + b) \\u2212 x(1 + b). Notice that 1 + b can be factored out, resulting in (1 + b)(1 \\u2212 x).

Therefore, the factored form of 1 \\u2212 bx \\u2212 x + b is (1 + b)(1 \\u2212 x).

To find the number that 37.5% of it equals 6, set up an equivalent fractions equation, cross-multiply, and solve for the unknown number. In this case, 37.5% of 16 is 6.

The question pertains to finding a certain number when given a percentage of that number. Here, we're asked to find the number of which '37.5% is 6'. We can solve this through simple arithmetic and the use of equivalent fractions. An important rule to remember is that 'percentage' literally means 'per 100', so 37.5% can be written as the fraction 37.5/100.

To find the unknown number (let's call it X), you can set up the equation 37.5/100 = 6/x, where 'x' is the number we're trying to find. Then you cross-multiply to solve for 'x': 37.5 * X = 6 * 100.
