Answer: D) 54 inches = 1 1/2 yards

explanation: 1 1/2 yards = 54 inches.

Answer:

The probability that he answered neither of the problems correctly ​is 0.0625.

Step-by-step explanation:

We are given that a student ran out of time on a multiple-choice exam and randomly guess the answers for two problems each problem have four answer choices ABCD and only one correct answer.

Let X = Number of problems correctly ​answered by a student.

The above situation can be represented through binomial distribution;

\(P(X=r)=\binom{n}{r}\times p^{r}\times (1-p)^{n-r};x=0,1,2,3,....\)    

where, n = number of trials (samples) taken = 2 problems

           r = number of success = neither of the problems are correct

           p = probability of success which in our question is probability that

                 a student answer correctly, i.e; p = \(\frac{1}{4}\) = 0.75.

So, X ~ Binom(n = 2, p = 0.75)

Now, the probability that he answered neither of the problems correctly ​is given by = P(X = 0)

             P(X = 0) = \(\binom{2}{0}\times 0.75^{0}\times (1-0.75)^{2-0}\)

                            = \(1 \times 1\times 0.25^{2}\)

                            = 0.0625

The probability that the friend is between 10 and 30 minutes late is approximately 0.6667, or 66.67%.

Since the probability density function is uniform, the probability of the friend being between 10 and 30 minutes late is equal to the area of the rectangle that lies between x = 10 and x = 30, and below the curve of the probability density function.

The height of the rectangle is equal to the maximum value of the probability density function, which is 1/30 since the interval of possible values for x is [0, 30] minutes.

The width of the rectangle is equal to the difference between the upper and lower limits of the interval, which is 30 - 10 = 20 minutes.

Therefore, the probability of the friend being between 10 and 30 minutes late is:

P(10 < x < 30) = (height of rectangle) x (width of rectangle)

= (1/30) x 20

= 2/3

≈ 0.6667

So the probability that the friend is between 10 and 30 minutes late is approximately 0.6667, or 66.67%.

Step-by-step explanation:

The scale factor used is:

1 centimeter equals half millimiter.

The scale factor tells us how many units in the sculpture represent a real unit.

We know that:

Real length = 9mm

Length in the sculpture = 18cm

Then we have the relation between the lengths:

18cm = 9mm

Dividing both sides by 18 we will get:

1cm = 9mm/18

1cm = 0.5mm

Using equations we can solve for y, using the value of x as follows:

x = 1 is, y =4

x = 2 is, y = 7

x = 3 is, y = 10

x = -1 is, y = -2

The missing ordered pairs are:

(2, 7)

(3, 10)

(-1, -2)

Equations are logical assertions in mathematics that have two algebraic expressions on either side of an equals (=) sign. The expression on the left and the expression on the right are shown to be equal in reference to one another. All equations in mathematics start with LHS = RHS (left hand side = right hand side).

The value of an unknown variable, which equates to an unidentified quantity, can be determined through solving equations. In the absence of a "equal to" symbol, the statement is not an equation. That shall be taken into account as an expression.

here, the given equation is:

y = 3x + 1

Now putting the different values of x in the equation we can get the

respective values of y.

y = 3 × 1 + 1

⇒ y =4

So, when x = 1, y = 4

Similarly,

When x = 2, y = 7

When x = 3, y = 10

When x = -1, y = -2

Hence, the ordered pairs are: (2, 7), (3, 10) and (-1, -2).

Answer:

Step-by-step explanation:

Answer:

21.4%

Step-by-step explanation:

You would pay back a 21.4%

The simple interest rate on the loan of $1400 is approximately 21.4% per year.

The simple interest can be expressed as:

A = P( 1 + rt )

Where A is accrued amount, P is the principal, r is the interest rate and t is time.

Given the parameter:

Principal P = $1400

Accrued amount A = $2000

Time t = 2 years

Interest rate r =?

Plug these values into the above formula and solve for the interest rate.

A = P( 1 + rt )

\(r = \frac{1}{t} * ( \frac{A}{P} - 1 ) \\\\r = \frac{1}{2} * ( \frac{2000}{1400} - 1 ) \\\\r = \frac{1}{2} * ( \frac{2000}{1400} - 1 ) \\\\r = 0.21428\)

Convert r decimal to R a percentage

R = 0.214 × 100

R = 21.4% per year

Therefore, the rate is approximately 21.4% per year.

The total number of rows in the Theater after 125 seats are added is 60 rows.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The Outdoor theater currently has 1,375 seats.

If we add 125 new seats then the number of seats are

= 1375 + 125

= 1500

Each row have 25 seats in one row.

\(18*(7*(-3))=18*7+18*(-3)\\18*-21=126 - 54\\-378 \neq 72\)

LHS \(\neq\) RHS

Answer :

To verify an equation, we need to see if the LHS = RHS.

Equation \(\downarrow\)

\(18\times(7\times(-3))=18\times7+18\times(-3)\)

Let's solve the left hand side (LHS) first.

\(18\times(7\times(-3))\\= 18 \times (-21)\\=\underline{ -378}\)

Now, let's solve the right hand side (RHS).

\(18\times7+18\times(-3)\\= 126 - 54\\=\underline {72}\)

But,

\(\boxed{-378 \neq 72}\)

We can see that the LHS doesn't match or isn't equal to the RHS.

Hence, we can say that LHS \(\neq\) RHS & the  equation is NOT true.

Step-by-step explanation:

The expression that is equivalent to StartRoot \(8 x^7 y^8\) EndRoot is (\(2 x^3 y^4\) StartRoot 2 x EndRoot)^2.

To understand why this is the case, let's break down each expression and simplify them step by step:

StartRoot \(8 x^7 y^8\) EndRoot:

We can rewrite 8 as \(2^3\), and since the square root can be split over multiplication, we have StartRoot \((2^3) x^7 y^8\) EndRoot. Applying the exponent rule for square roots, we get StartRoot \(2^3\) EndRoot StartRoot \(x^7\) EndRoot StartRoot \(y^8\) EndRoot.

Simplifying further, we have 2 StartRoot \(2 x^3 y^4\) EndRoot StartRoot \(2^2\) EndRoot StartRoot \(x^2\) EndRoot StartRoot \(y^4\) EndRoot. Finally, we obtain 2 \(x^3 y^4\) StartRoot 2 x EndRoot, which is the expression in question.

(\(2 x y^2\) StartRoot 8 x^3 EndRoot)^2:

Expanding the expression inside the parentheses, we have \(2 x y^2\)StartRoot \((2^3) x^3\) EndRoot. Applying the exponent rule for square roots, we get \(2 x y^2\) StartRoot \(2^3\) EndRoot StartRoot \(x^3\) EndRoot.

Simplifying further, we have \(2 x y^2\) StartRoot 2 x EndRoot. Squaring the entire expression, we obtain (\(2 x y^2\) StartRoot 2 x EndRoot)^2.

Therefore, the expression (\(2 x^3 y^4\) StartRoot 2 x EndRoot)^2 is equivalent to StartRoot \(8 x^7 y^8\) EndRoot.

980 intervals.

Step-by-step explanation:

For each interval, there are only two possible outcomes. Either it captures the population mean, or it does not. One interval is independent of other intervals. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

\(E(X) = np\)

98% confidence interval

Has a 98% probability of capturing the population mean, so \(p = 0.98\)

1000 intervals

This means that \(n = 1000\)

How many of these 1000 intervals do you expect to capture the corresponding value of μ?

\(E(X) = np = 1000*0.98 = 980\)

980 intervals.
