Step-by-step explanation:

Answer:

0.1515

Step-by-step explanation:

To convert 1 mile to 800 feet, we can set up a proportion:

\( \frac{1 mile}{5,280 feet} = \frac{x \: miles}{800 feet} \)

where x is the number of miles equivalent to 800 feet. To solve for x, we can cross-multiply:

\({5,280 feet}^{x miles} = {800 \: \: feet}^{1 mile}\)

Dividing both sides by 5,280 feet, we get:

\(x miles = \frac{800 feet}{5,280 feet} \\ x miles = 0.1515151515 miles\)

Therefore, 1 mile is equivalent to approximately 0.1515 miles or 800 feet is equivalent to approximately 0.1515 miles.

Logarithmic equations with negative logs have no solution. Always use the original logarithmic equation to check for solved values.

The rules apply to any logarithm logbx, with the exception that any occurrence of e must be replaced with the new base b. Equations (1) and (2) defined the natural log. It is acceptable for x to be 0 or negative. However, when substituted or evaluated into the original logarithm equation, it is not allowed to have a logarithm of a negative number or a logarithm of zero, 0.

If we solve for x using log rules and properties, then plug those x values into the original equation, the equation should be satisfied. Also, keep in mind that the log's argument after plugging in the x values must be positive. There is no solution because the log's argument is negative.

The probability of getting at least 2 defective chips out of 8 is 0.0061, or about 0.61%

To solve this problem, we need to use the binomial distribution formula, which is:

P(X = k) = nCk * p^k * (1-p)^(n-k)

Where:
- P(X = k) is the probability of getting k successes
- n is the total number of trials (in this case, n = 8)
- k is the number of successes we're interested in (at least 2, so we need to calculate P(X = 2) + P(X = 3) + ... + P(X = 8))
- p is the probability of getting success on one trial (in this case, p = 0.01)

So let's calculate each term:

P(X = 2) = 8C2 * 0.01^2 * (1-0.01)^(8-2) = 0.0059
P(X = 3) = 8C3 * 0.01^3 * (1-0.01)^(8-3) = 0.0002
P(X = 4) = 8C4 * 0.01^4 * (1-0.01)^(8-4) = 0.0000
P(X = 5) = 8C5 * 0.01^5 * (1-0.01)^(8-5) = 0.0000
P(X = 6) = 8C6 * 0.01^6 * (1-0.01)^(8-6) = 0.0000
P(X = 7) = 8C7 * 0.01^7 * (1-0.01)^(8-7) = 0.0000
P(X = 8) = 8C8 * 0.01^8 * (1-0.01)^(8-8) = 0.0000

Now we can add up all the probabilities:

P(at least 2 defective chips) = P(X = 2) + P(X = 3) + ... + P(X = 8) = 0.0061

So the probability of getting at least 2 defective chips out of 8 is 0.0061, or about 0.61%. This is a relatively small probability, but it's not impossible, so the manufacturer should still take measures to minimize the number of defective chips produced.

3)  since we don't have the information about the interest paid (I), we cannot determine the rate of interest at this time.

(1) To find the total amount Adrian paid in 36 months, we can multiply the monthly installment by the number of installments:

Total payment A = Monthly installment * Number of installments

              = $375 * 36

              = $13,500

Therefore, Adrian paid a total of $13,500 over the course of 36 months.

(2) In the simple interest formula I = Prt, the letters used represent the following variables:

I: Interest (the amount of interest paid)

P: Principal (the initial amount, or in this case, the car worth)

r: Rate of interest (expressed as a decimal)

The other root can be found using the formula of the roots of a quadratic equation which states that the roots of a quadratic equation are given by:

\($$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$\)

The coefficients of the quadratic equation. Since the quadratic equation has complex roots, the coefficients must be real and the discriminant

\($(b^2 - 4ac)$\) must be negative.

Substituting the given values into the equation, we have:

\($$(2+j4)^2 + b(2+j4) + c\) = 0

Expanding the terms, we get:

Step-by-step explanation:

In the question it is given that the volume of a sphere is 4,500π cubic yards. And we have to find the radius.

We know that,

Now, Substituting the values in the fomulae :

⇒ 4/3πr³ = 4500π

Cancelling π from both sides :

⇒ 4/3r³ = 4500

⇒ 4r³ = 4500 × 3

⇒ 4r³ = 13500

⇒ r³ = 13500/4

⇒ r³ = 3375

Taking cube root on both sides we get :

⇒ r = 15

Therefore,

Answer:

Step-by-step explanation:

In this question we have provided volume of sphere that is 4500π cubic yards . And we are asked to find the radius of the sphere .

We know that ,

\( \qquad \: \frak{Volume_{(Sphere)} = \dfrac{4}{3}\pi r {}^{3} } \quad \bigstar\)

Where ,

Solution : -

As in the question it is given that volume of sphere is 4500π . So equation it with volume formula :

\( \dashrightarrow \: \qquad \: \dfrac{4}{3} \pi r {}^{3} = 4500\pi\)

Step 1 : Cancelling π as they are present on both sides :

\(\dashrightarrow \: \qquad \: \dfrac{4}{3} \cancel{\pi }r {}^{3} = 4500 \cancel{\pi}\)

We get ,

\(\dashrightarrow \: \qquad \: \dfrac{4}{3} r {}^{3} = 4500\)

Step 2 : Multiplying with 3/4 on both sides :

\(\dashrightarrow \: \qquad \: \dfrac{ \cancel{4}}{ \cancel{ 3}} r {}^{ 3} \times \dfrac{ \cancel{3}}{ \cancel{4}} = \cancel{ 4500} \times \dfrac{3}{ \cancel{4} }\)

On further calculations, We get :

\(\dashrightarrow \: \qquad \: r {}^{3} = 1125 \times 3\)

\(\dashrightarrow \: \qquad \:r {}^{3} = 3375\)

Step 3 : Applying cube root on both sides :

\(\dashrightarrow \: \qquad \: \sqrt[3]{r {}^{3} } = \sqrt[3]{3375} \)

We get :

Step-by-step explanation:

A good trick for fractions is to take the top number and divide it by the bottom number. This gives you the number version of the fraction. For example in question 4. 5/4 is 1.25. And 10/8 is 1.25. therefore they have the same value. Also another good trick. If the top number is more than the bottom number we know it will be 1 something because their is more than the bottom number. So if we have for example question 3 we know that 4 thirds will be at least 1 something if we divide it. And if we look at 8 ninths we know it will be less than 1 something since I is less than nine. Therefore if divided they will have different numbers

Damian earn $43 on friday if he works for 2. 75 hours and is obtained by putting value of time in function f(x).

since the function f(x) = 12x+10 is the function which models the amount Damain earns on each day working x hours, so we have the value of x which is 2.75 for this question so, after putting the value of x in f(x) we will get total earning of Damian on that day.

the function that calculates the total earning of damian on each day is given by the function :

    f(x) = 12x + 10  

 so by working 1 hour we get

   f(1) = 12 * 1 +10 = $22

  it is given that on firday damain works 2.75 hours so we have to find   f(2.75)

f(2.75) = 12 * 2. 75 +10 = 33 +10

When forecasting techniques are being considered, an analyst must choose between two techniques for weekly sales of roller blades. The two techniques are linear trend equation and naive approach. The linear trend equation is given as \(F_t\) = 127 + 2.1t.

Linear Trend Equation: Linear trend equation is one of the forecasting techniques used to predict trends and estimate the relationship between variables. It is calculated as\(F_t\) = a + bt, where \(F_t\)represents the forecasting value, b represents the slope and a represents the y-intercept.

The equation is used to forecast values for the dependent variable based on independent variables. The linear trend equation is used to forecast future values and interpret the relationship between variables. The equation can be used to forecast the trend of data that shows a linear trend or a straight line, as well as predict values for future periods in time.

Naive Approach : The Naive approach is one of the simplest forecasting techniques used to make predictions. This method assumes that the best estimate of a future value is the current value. It is based on the belief that the most recent value of a time series provides the best estimate of the future.

In conclusion, the analyst must choose between two forecasting techniques, linear trend equation and naive approach. The linear trend equation is based on estimating the relationship between variables, while the Naive approach assumes that the best estimate of a future value is the current value.
