This equation is incorrect because it is missing a division sign between 1.7 and 0.65p. The correct equation should be t = (1.7 / 0.65p) * 0.10

First, we need to isolate the variable 't' in the equation. To do this, we need to divide both sides of the equation by 0.10. This will give us 0.65p/0.10 = 1.70/0.10, which simplifies to t = (1.7 / 0.65p) * 0.10. This is the correct equation that we need to solve for 't'.

t = (1.7 / 0.65p) * 0.10

t = (1.7 / (0.65 * p)) * 0.10

t = (17 / (6.5 * p)) * 0.1

t = (17 * 0.1) / (6.5 * p)

t = (1.7) / (6.5 * p)

Step-by-step explanation:

You add all of your numbers up, and then you divide by how many numbers you have.

Part a: The margin of error and the interval estimate is E = 0.027 and 0.6120 < p < 0.666 respectively.

Part b:  The margin of error and the interval estimate is E = 0.027 and 0.3900 < p < 0.4440 respectively.

Considering the first query;

Since the confidence level for the question is 95%, the level of importance is;

α = (100 - 95)%

α = 0.05

Typically, the crucial value of comes out from normal distribution table of α/2 is;

Z(α/2) = 1.96

Typically, this margin of error is denoted mathematically as follows:

E = Z(α/2)*√P₁(1 - P₁)/n

E = 1.96*√0.639(1 - 0.639)/1200

E = 0.027

Mathematically, a 95% Interval estimate is typically written as;

P₁ - E < p < P₁ +E

0.639 - 0.027 < p < 0.639 + 0.027

0.6120 < p < 0.666

Thus, the margin of error and the interval estimate is E = 0.027 and 0.6120 < p < 0.666 respectively.

Part (b)

Since the confidence level for the question is 95%, the level of importance is;

α = (100 - 95)%

α = 0.05

Typically, the crucial value of comes from the normal distribution table and is;

Z(α/2) = 1.96

E = 0.027

Mathematically, a 95% Interval estimate is typically written as;

P₁ - E < p < P₁ +E

0.417 - 0.027 < p < 0.417 + 0.027

0.3900 < p < 0.4440

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Let,The no. of tapes be 'x' and the no. of CD be 'y'.

Given, She bought no more than 20 recordings.

Therefore, x + y ≤ 20.

And,

Each tape cost $5.95 and each CD cost $8.95.

An equation of line having slope 1/4 and passes through the point (-4,-3) is y = 1/4x - 2

We know that the slope-point form of line is:

(y - y1) = m(x - x1)

Here, we need to find an equation of line having slope 1/4 and passes pae through the point (-4,-3)

let (x1, y1) = (-4, -3)

and m = 1/4

substitute values in above formula,

(y - (-3)) = 1/4 (x +4)

y + 3 = 1/4 (x+4)

y = 1/4x -2

∠1 and ∠3 are adjacent angles

∠1 and ∠2 are supplementary angles

Vertically opposing angles are established when two lines intersect at a single place and the angles opposite to each other are created using the two intersecting lines. There is never a difference between these angles.

Those angles are referred to as vertical angles if they share an arm and a vertex. Additionally, the nearby angles are those that are produced side by side. The primary characteristic of these angles is that they never cross over.

When two angles add up to 180 degrees, they are said to be supplementary. Angles are referred to be supplementary angles when two of them are next to one another.

Answer:

7.4 mins

Step-by-step explanation:

135 -----> 1 min

1000 ----> x

1000/135 mins = x

= 7.4 mins

Answer:

To determine how long it will take to fill 1000 containers at a rate of 135 containers per minute, you can use the formula: time = number of containers / filling rate. In this case, the filling rate is 135 containers per minute, and the number of containers you want to fill is 1000. Plugging these values into the formula, we get: time = 1000 / 135 = 7.41 minutes.

The answer is 11(a - b), To solve this expression, we need to perform the subtraction operation on the terms inside the parentheses. First, we subtract the term "a + 6b" from "12a - 5b". This gives us 11a - 11b. Then, we can simplify this expression by combining the like terms 11a and -11b to get 11a - 11b = 11(a - b). This is the final answer.

We have,

a = 27

Common ratio:

The sum of the geometric sequence.

S(n) = a (1 - [tex]r^n[/tex]) / (1 - r)

Now,

a = 27,

r = -1/3

S(20):

The lowest term of 38/46 can be expressed as a decimal as 0.826087 and percentage as 82.6087%.

The fraction 38/46 is equivalent to 19/23.

Once the absolute value of the top number, or numerator, (38) is less than the absolute value of the bottom number, or denominator, the fraction is considered to be correct (46).

The fraction 38/46 can be reduced.

To make things simpler, we'll employ the Greatest Common Factor (GCF) technique.

The GCF is the largest number equally divisible by two or more other numbers.

The numerator and denominator factors are listed, and the greatest number repeated in both lists is used to calculate the GCF:

The factors of 38 exists 1,2,19,38;

The factors of 46 exists 1,2,23,46.

We can see that the GCD is 2 because it is the largest number by which 38 y 46 can be divided without leaving any residue.

Simply divide the numerator and denominator by 2 to lower this fraction (the GCF).

So, [tex]$\frac{38}{46}=\frac{38 \div 2}{46 \div 2}=\frac{19}{23}$[/tex]

Therefore, 38/46 exists equivalent to 19/23 in the reduced form.

The factors exists numbers that multiply each other to get another number.

The fraction 38/46 exists even equivalent to 38÷46 and can also be expressed as a decimal as 0.826087 and expressed as a percentage as 82.6087%.

Answer:

y = -0.11x + 0.89

Step-by-step explanation:

First find the slope of the tangent line, which is equal to dy/dx

Find the derivative of y at 1:

dy = cos(t) + 2cos(2t)

dy = cos(1) + 2cos(2)

dy = -0.292

Then the derivative of x at -1:

dx = -sin(t) - 2sin(2t)

dx = -sin(-1) - 2sin(-2)

dx = 2.66

So now calculate dy/dx:

dy/dx = -0.11

Now use point slope form to find the equation of the tangent line:

y - 1 = -0.11(x + 1)

y - 1 = -0.11x - 0.11

y = -0.11x + 0.89
