Answer:

-5

Step-by-step explanation:

We can find the slope between two points by using

m = (y2-y1)/(x2-x1)

    = ( -9-6)/(-6 - -9)

   =(-9-6)/( -6+9)

  -15/3

   -5

Answer:

C

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (- 9, 6) and (x₂, y₂ ) = (- 6, - 9)

m = \(\frac{-9-6}{-6+9}\) = \(\frac{-15}{3}\) = - 5 → C

\(\boxed {\boxed {\sf SA= 753.6 \ in^2}}\)

Step-by-step explanation:

The surface area of a cylinder is found using this formula.

\(SA=2 \pi rh+ 2 \pi r^2\)

We know the diameter is 20 inches and the height is 2 inches. We must find the radius.

Now we know that:

\(r= 10 \ in \\h= 2 \ in\)

Substitute the values into the formula. Also, plug 3.14 in for pi.

\(SA=2 (3.14)(10 \ in)(2 \ in)+ 2 (3.14)(10 \ in)^2\)

Solve according to PEMDAS: parentheses, exponents, multiplication, division, addition, and subtraction.

Solve the exponent.

\(SA=2 (3.14)(10 \ in)(2 \ in)+ 2 (3.14)(100 \ in^2)\)

Multiply all the numbers together.

\(SA=2 (3.14)(20 \ in^2)+ 2 (3.14)(100 \ in^2)\)

\(SA=125.6 \ in^2+628 \ in^2\)

Add.

\(SA= 753.6 \ in^2\)

The surface of the cylinder is 753.6 square inches.

The expected value of the total number of tosses is 1/(p + q).

Let's break down the problem step by step:

First, we toss coin A until we obtain heads for the first time. The expected number of tosses for this is 1/p, where p is the probability of obtaining heads with coin A.

Once we obtain heads with coin A, we move on to tossing coin B until we obtain heads for the first time. The expected number of tosses for this is 1/q, where q is the probability of obtaining heads with coin B.

Since the tosses of coin A and coin B are independent, we can sum up the expected number of tosses for each coin to find the total expected number of tosses.

Therefore, the total expected number of tosses is 1/p + 1/q.

In the given exercise, the probabilities of obtaining heads with coin A and coin B are not specified, so we cannot provide a specific numerical answer. However, the general formula for the expected value of the total number of tosses is 1/(p + q).

In the given equation r = 2/5 t "r" is the dependent variable.

In mathematics, a variable is a symbol that represents a quantity that can take on different values. In many cases, variables can be divided into two types: dependent variables and independent variables.

An independent variable is a variable that can be changed freely, and its value is not dependent on any other variable in the equation.

A dependent variable is a variable whose value depends on the value of one or more other variables in the equation

Answer:

Step-by-step explanation:

The value of Expected value, variance, and standard deviation of y of given probability distribution is 6.4, 9.76 and 3.12 respectively.

To compute the expected value of y, denoted E(y), we use the formula:

E(y) = Σ [y × f(y)]

Using the given probability distribution, we have:

E(y) = (2 × 0.20) + (4 × 0.30) + (7 × 0.40) + (8 × 0.10) = 1.6 + 1.2 + 2.8 + 0.8 = 6.4

Therefore, the expected value of y is 6.4, rounded to 1 decimal place.

To compute the variance of y, denoted Var(y), we use the formula:

Var(y) = E(y^2) - [E(y)]^2

where E(y) is the expected value of y, and E(y^2) is the expected value of y squared. To find E(y^2), we use the formula:

E(y^2) = Σ [y^2 × f(y)]

Using the given probability distribution:

E(y^2) = (2^2 × 0.20) + (4^2 × 0.30) + (7^2 × 0.40) + (8^2 × 0.10) = 1.6 + 3.6 + 19.6 + 6.4 = 31.2

Substituting this and the previously calculated E(y) into the formula for Var(y), we get:

Var(y) = E(y^2) - [E(y)]^2 = 31.2 - 6.4^2 = 31.2 - 40.96 = 9.76

Therefore, the variance of y is 9.76, rounded to 2 decimal places.

we take the square root of the variance to find the standard deviation:

σ = √Var(y) = √9.76 = 3.12

Therefore, the standard deviation of y is 3.12, rounded to 2 decimal places.

Answer: The area of a rectangular room is 750 square feet and the width of the room is 5 feet less than the length of the room.

Three equations that can be used to solve for y, the length of the room are:

y(y + 5) = 750: This equation uses the formula for the area of a rectangle, which is length x width. Since the width is 5 feet less than the length, we can substitute y-5 for the width.

750 – y(y – 5) = 0: This equation uses the same method as the first equation, but it is rearranged to solve for y.

(y + 25)(y – 30) = 0: This equation uses the quadratic formula to solve for the length of the room, this equation is also useful when the length is an irrational number.

Note that the fourth equation y(y – 5) + 750 = 0 is not valid because it is not possible to have negative area, hence y(y-5) should not be added to 750.

The fifth equation (y+25)(y-30)=0 is also not valid because it gives y = -25 and y = 30 as solutions but the length of the room can't be negative.

  C.  19.50 lbs

Step-by-step explanation:

3 feet 3 inches is nearly 4 feet, but is a little shorter. That means the weight of the bar will be nearly 24 pounds, but a little less.

It cannot be 29 or 78 pounds, because those weights are more than 24 pounds. It cannot be 3 pounds, because that weight is significantly less. The only viable answer choice is 19.50 pounds.

__

We assume the weight is proportional to the length. Then the weight (w) of the shorter bar will be ...

  w/39 = 24/48 . . . . . weight in pounds/length in inches

  w = 39(24/48) = 39/2 = 19.5

The weight of the shorter bar is 19.5 pounds.

The polynomial that passes through the given points is \(P(x) = (5x^2 - 13x + 8) / 6.\)

To find a polynomial that passes through the given points (1, 1), (2, 4), and (4, 10) using Lagrange interpolation, we can construct a polynomial of degree two since we have three points.

The Lagrange interpolation formula states that for a set of distinct points (xi, yi), the polynomial P(x) that passes through these points is given by:

P(x) = Σ [yi * Li(x)], where Li(x) = Π [(x - xj) / (xi - xj)], for i ≠ j.

Let's calculate the polynomial:

For the point (1, 1):

L1(x) = [(x - 2)(x - 4)] / [(1 - 2)(1 - 4)] = (x - 2)(x - 4) / 3

For the point (2, 4):

L2(x) = [(x - 1)(x - 4)] / [(2 - 1)(2 - 4)] = -(x - 1)(x - 4) / 2

For the point (4, 10):

L3(x) = [(x - 1)(x - 2)] / [(4 - 1)(4 - 2)] = (x - 1)(x - 2) / 6

Now, we can substitute the values into the Lagrange interpolation formula:

P(x) = 1 * (x - 2)(x - 4) / 3 + 4 * -(x - 1)(x - 4) / 2 + 10 * (x - 1)(x - 2) / 6

Simplifying, we get:

\(P(x) = (x^2 - 3x + 2) / 3 - 2(x^2 - 5x + 4) / 2 + 5(x^2 - 3x + 2) / 6\\P(x) = (x^2 - 3x + 2) - (x^2 - 5x + 4) + (5x^2 - 15x + 10) / 6\\P(x) = (5x^2 - 13x + 8) / 6\)

Therefore, the polynomial that passes through the given points is \(P(x) = (5x^2 - 13x + 8) / 6.\)

Answer:

89.6

Step-by-step explanation:

The formula to convert Celsius to Fahrenheit is given by °F = °C × (9/5) + 32

F = [ C × (9/5) + 32 ]

Given that, C = 32

F = 32 × (9/5) + 32

F = 32 [ 1 + (9/5) ]

F = 32 [ 1 + 1.8 ]

F = 32 × 2.8

F = 89.6

The solution to the equation -1/2w - 3/5 = 1/5w is w = -6/7, meaning that w equals negative six-sevenths when the equation is true.

To solve the equation -1/2w - 3/5 = 1/5w, we'll start by simplifying and rearranging the terms to isolate the variable w.

First, we'll combine like terms on the left side of the equation:

-1/2w - 3/5 = 1/5w

To make the equation easier to work with, let's get rid of the fractions by multiplying every term in the equation by the common denominator, which is 10:

10 * (-1/2w) - 10 * (3/5) = 10 * (1/5w)

This simplifies to:

-5w - 6 = 2w

Next, we'll group the w terms on one side of the equation and the constant terms on the other side:

-5w - 2w = 6

Combining like terms, we have:

-7w = 6

Now, we'll isolate the variable w by dividing both sides of the equation by -7:

(-7w)/(-7) = 6/(-7)

This simplifies to:

w = -6/7

Therefore, the solution to the equation -1/2w - 3/5 = 1/5w is w = -6/7.

In conclusion, w is equal to -6/7 when the equation -1/2w - 3/5 = 1/5w is satisfied.
