How many minutes would you have to exercise each day to have a resting heart rate of 60 beats per minute?

Answer:

(1,-9)

Step-by-step explanation:

Answer:

- x + 2y = 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

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

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (3, 2)

m = \(\frac{2-0}{3+1}\) = \(\frac{2}{4}\) = \(\frac{1}{2}\), thus

y = \(\frac{1}{2}\) x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 2) , then

2 = \(\frac{3}{2}\) + c ⇒ c = 2 - \(\frac{3}{2}\) = \(\frac{1}{2}\)

y = \(\frac{1}{2}\) x + \(\frac{1}{2}\) ← in slope- intercept form

Multiply through by 2

2y = x + 1 ( subtract x from both sides )

- x + 2y = 1 ← in standard form

There are 8.0658 × \(10^{67}\) more form to shuffle a deck of cards than atoms.

What is the factorial?

Factorial is an important function, which is used to find how many ways things can be arranged or the ordered set of numbers.The factorial of a whole number is the function that multiplies the number by  number below it.

The number of ways to shuffle a deck of cards is astronomically large, far greater than the estimated number of atoms in the observable universe.

A standard deck of 52 playing cards can be arranged in 52 factorial ways, denoted as 52!. This means multiplying all the positive integers from 1 to 52 together:

52! = 52 × 51 × 50 × ... × 3 × 2 × 1=8.0658 × \(10^{67}\).

Therefore,the exact value of 52! is an  large number, approximately equal to 8.0658×\(10^{67}\).

Hey There!!~

Because, First thing to do is mulpity 2 x 8 = 16 so, You bring the 6 and bring up the 1. Then, 5 x 8 = 40 + 1 = 41. So, we bring down the 1 and bring up the 4. Then, 3 x 8 = 24 + 4 = 28. Then, The same thing bring down the 8 and let the 2 stay up there. 7 x 8 = 56 + 2 = 58. So, Right now the answer is 58, 816. So, We just completed the first step, But we're are not done yet... 4 x 2 = 8. Then, 5 x 4 = 20. So, we bring down the 0 and bring up the 2. Then, 4 x 3 = 12 + 2 = 14. So, The 4 stay down and 1 goes up. Then, 7 x 4 = 28 + 1 = 29. So, we just completed the second step. The last step is to add 58, 816 + 29, 408 = 352, 896. Hope This helps!!

The probability that over 40% will be willing to switch companies if offered a higher salary is 5%.

This problem can be modeled by a binomial distribution with n = 100 and p = 0.35. We want to find the probability that more than 40% (i.e., 0.4) of the executives in the sample are willing to switch companies.

Using the normal approximation to the binomial distribution, we can calculate the mean and standard deviation of the sample proportion as:

mean = np = 100 × 0.35 = 35

standard deviation = √(np(1-p)) = sqrt(100 × 0.35 × 0.65) ≈ 4.16

To standardize the distribution, we calculate the z-score:

z = (0.4 × 100 - 35) / 4.16 ≈ 1.68

Using a standard normal table or calculator, we find that the probability of a z-score greater than 1.68 is about 0.0465. Therefore, the probability that over 40% of the executives in the sample are willing to switch companies is approximately 0.0465 or 4.65%.

It took 1700 J of work to stretch a spring from its natural length of 2 m to a length of 6 m. The spring constant k will be 212.5 N/m.

The potential energy stored in a spring is given by the formula:

PE = (1/2) kx^2

where k is the spring constant, x is the displacement from the equilibrium position, and PE is the potential energy.

In this problem, the spring is stretched from its natural length of 2 m to a length of 6 m, so the displacement is x = 6 m - 2 m = 4 m.

The work done on the spring is equal to the change in potential energy, so:

Work = PE final - PE initial

1700 J = (1/2) k(4² - (1/2) k(0)²

1700 J = 8k

k = 212.5 N/m

Therefore, the spring constant is 212.5 N/m.

m<ACB  = 59degrees

Step-by-step explanation:

To get <ACB, first we need arcAB

arcAB + arcAC + arcBC = 360

arcAB + 89 + 153 = 360

arcAB+242 = 360

arcAB = 360 - 242

arcAB = 118

Also, m<ACB = 1/2arcAB

m<ACB = 1/2*118

m<ACB  = 59degrees

The variable x is 9 and the two adjacent angles have measures of 117° and 63°, respectively.

Parallelograms are quadrilaterals with two pairs of parallel sides of equal length. According to Euclidean geometry, the measures of two adjacent angles in a parallelogram are supplementary. Thus,

13 · x + 7 · x = 180°

II is higher. When there is very little scatter around the regression line, it means that the data points are tightly clustered and the relationship between the variables is strong.

In this scenario, the slope estimate, b1, is likely to be more precise and have less uncertainty. The regression line will have a small standard error of estimate, indicating that the predicted values are close to the actual values.

On the other hand, when there is a lot of scatter around the regression line, it means that the data points are more spread out and the relationship between the variables is weaker. In this scenario, the slope estimate, b1, is likely to be less precise and have more uncertainty. The regression line will have a larger standard error of estimate, indicating that the predicted values are further from the actual values.

In summary, the amount of scatter around the regression line affects the precision of the slope estimate. When there is very little scatter, the slope estimate is likely to be more precise and have less uncertainty. Conversely, when there is a lot of scatter, the slope estimate is likely to be less precise and have more uncertainty.

The probability of getting the same number of heads on the first two tosses as on the second two tosses is 1/4.

The probability of getting the same number of heads on the first two tosses as on the second two tosses is 1/4. This is because there are only four possible outcomes of tossing a fair coin four times: HHHT, HTHH, THHH, and TTHT. Of these four outcomes, only one has the same number of heads on the first two tosses as on the second two tosses (HTHH). Therefore, the probability of this outcome occurring is 1/4. This can also be determined by considering the possible combinations of heads and tails. There are 16 possible combinations of heads and tails when tossing a coin four times, and four of those combinations are HTHH. This means that, out of the 16 possible combinations, 4 of them will have the same number of heads on the first two tosses as on the second two tosses, making the probability of this outcome 1/4.

The edge length of each cube, out of 27 similar cubes with a total volume of 3375 cm³, is 5 cm.

To find the edge length of one cube, we can divide the total volume of the cubes by the number of cubes.

Given:

Total volume of 27 cubes = 3375 cm³

We need to find the edge length of one cube.

Let's denote the edge length of one cube as "x."

The volume of a cube is calculated by taking the cube of its edge length:

Volume of one cube = x³

Since we have 27 cubes with the same edge length, the total volume is the sum of the volumes of all the cubes:

Total volume of 27 cubes = Volume of one cube × Number of cubes

3375 cm³ = x³ × 27

To solve for x, we divide both sides of the equation by 27:

3375 cm³ / 27 = x³

125 cm³ = x³

Taking the cube root of both sides gives us:

∛125 cm³ = ∛x³

5 cm = x

Therefore, the edge length of one cube is 5 cm.

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

5x - y = 2 ( subtract 5x from both sides )

- y = - 5x + 2 ( multiply through by - 1 )

y = 5x - 2 ← in slope- intercept form

with slope m = 5

(a)

given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{5}\) , then

y = - \(\frac{1}{5}\) x + c ← is the partial equation

to find c substitute (15, 2 ) into the partial equation

2 = - \(\frac{1}{5}\) (15) + c = - 3 + c ( add 3 to both sides )

5 = c

y = - \(\frac{1}{5}\) x + 5 ← in slope- intercept form

(b)

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

y = - \(\frac{1}{5}\) x + 5 ( multiply through by 5 to clear the fraction )

5y = - x + 25 ( add x to both sides )

x + 5y = 25 ← in standard form

Given an AR(1) process with drift X = α + βX_{t-1} + ε_t, where α = 2, β = 0.7, and ε_t ~ N(0, 1).To find the mean of the process, we note that the AR(1) process has a mean of μ = α / (1 - β).

So, the mean is 6.67, the variance is 5.41, the first three ACF are 0.68, 0.326, and 0.161, and the first three PACF are 0.7, -0.131, and 0.003.

So, substituting α = 2 and β = 0.7,

we have:μ = α / (1 - β)

= 2 / (1 - 0.7)

= 6.67

To find the variance, we note that the AR(1) process has a variance of σ^2 = (1 / (1 - β^2)).

So, substituting β = 0.7,

we have:σ^2 = (1 / (1 - β^2))

= (1 / (1 - 0.7^2))

= 5.41

To find the first three autocorrelation functions (ACF) and the first 3 partial autocorrelation functions (PACF), we can use the formulas:ρ(k) = β^kρ(1)and

ϕ(k) = β^k for k ≥ 1 and

ρ(0) = 1andϕ(0) = 1

To find the first three ACF, we can substitute k = 1, k = 2, and k = 3 into the formula:

ρ(k) = β^kρ(1) and use the fact that

ρ(1) = β / (1 - β^2).

So, we have:ρ(1) = β / (1 - β^2)

= 0.68ρ(2) = β^2ρ(1)

= (0.7)^2(0.68) = 0.326ρ(3)

= β^3ρ(1) = (0.7)^3(0.68)

= 0.161

To find the first three PACF, we can use the Durbin-Levinson algorithm: ϕ(1) = β = 0.7

ϕ(2) = (ρ(2) - ϕ(1)ρ(1)) / (1 - ϕ(1)^2)

= (0.326 - 0.7(0.68)) / (1 - 0.7^2) = -0.131

ϕ(3) = (ρ(3) - ϕ(1)ρ(2) - ϕ(2)ρ(1)) / (1 - ϕ(1)^2 - ϕ(2)^2)

= (0.161 - 0.7(0.326) - (-0.131)(0.68)) / (1 - 0.7^2 - (-0.131)^2) = 0.003

Let us consider a binomial expression

For example,

x²+(a+b)x+ab

x²+ax+bx+ab

x(x+a)+b(x+a)

(x+a)(x+b)

Therefore, the above binomial expression has two factors (x+a) and (x+b).

Now by numericals

Consider, x²+12x+35

\( {x}^{2} + 12x + 35\\Factors\:of\: 35\: is\: 5\: and\:7 \\ {x}^{2} + 5x + 7x + 35 \\ x(x + 5) +7(x + 5) \\ (x + 5)(x + 7)\)

Here, (x+5) and (x+7) are the factors of the binomial expression x²+12x+35.

Answer:

Binomials are two-term expressions connected with a plus sign or minus sign, such as {ax+b}ax+b. The first term will always include a variable, while the second term may or may not. 1st: factoring is when you break a large number down into it's simplest divisible parts. Each one of these parts is called a "factor." So, for example, the number 6 can be evenly divided by four different numbers. 2nd:  A binomial is simply the addition or subtraction of two numbers, at least one of which contains a variable. Sometimes these variables have exponents, like x^5 or 5y^6. 3rd :When first factoring binomials, it can help to reorder equations with ascending variable terms. This means you find the highest possible number that both parts of the binomial are divisible by. If you're struggling, simply factor both numbers on their own, then see what the highest matching number is.

Step-by-step explanation:

the value of 2 tan¯¹(cosec tan¯¹x - tan cot¯¹x) is tan¯¹((1 - x)/(1 + x)), which can be further simplified to tan 1. Option A

To understand why the value is tan 1, let's break down the expression step by step. Starting from the innermost function, tan¯¹x represents the inverse tangent of x. Next, we have cot¯¹x, which is the inverse cotangent of x. Since the cotangent is the reciprocal of the tangent, cot¯¹x is equal to tan¯¹(1/x).

Moving to the outer function, we have cosec tan¯¹x. Here, tan¯¹x is the angle whose tangent is x, and cosec is the reciprocal of the sine function. Therefore, cosec tan¯¹x is equal to 1/sin(tan¯¹x), which simplifies to 1/cos¯¹x.

Now, we can substitute these values back into the original expression: 2 tan¯¹(cosec tan¯¹x - tan cot¯¹x) = 2 tan¯¹(1/cos¯¹x - tan tan¯¹(1/x)).

By applying the trigonometric identity tan(a - b) = (tan a - tan b)/(1 + tan a tan b), we can simplify the expression to 2 tan¯¹((1 - x)/(1 + x)).

Finally, the value of 2 tan¯¹(cosec tan¯¹x - tan cot¯¹x) is tan¯¹((1 - x)/(1 + x)), which can be further simplified to tan 1.

A ball is dropped from a height of 6 ft. assuming that on each bounce, the ball rebounds to one-third of its previous height, the total distance traveled by the ball is approximately 11.926 feet.

We have to calculate the distance traveled by the ball with the help of the given data, as shown below;The first height of the ball is 6 feet. Distance traveled by the ball at the first instance = 6 feet.The ball rebounds to one-third of its previous height, and the ball goes to a height of:6/3 = 2 feet.

Distance traveled by the ball after the first bounce = 6 + 2 + 2 = 10 feet.The ball rebounds again to one-third of its previous height, and the ball goes to a height of:2/3 = 0.6667 feet. Distance traveled by the ball after the second bounce = 10 + 0.6667 + 0.6667 = 11.3334 feet.

The ball rebounds again to one-third of its previous height, and the ball goes to a height of:0.6667/3 = 0.2222 feet. Distance traveled by the ball after the third bounce = 11.3334 + 0.2222 + 0.2222 = 11.7778 feet. The ball rebounds again to one-third of its previous height, and the ball goes to a height of:0.2222/3 = 0.0741 feet.

Distance traveled by the ball after the fourth bounce = 11.7778 + 0.0741 + 0.0741 = 11.926 feet. Therefore, the total distance traveled by the ball is approximately 11.926 feet.
