Answers

Answer 1

The required equation has the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p is 230p – 1010 = 650p – 400 – p.

What is an equivalent expression?

Equivalent expressions are even though they appear to be distinct, their expressions are the same. when the values are substituted into the expression, both expressions produce the same result and are referred to be equivalent expressions.

We have the given expression below:

⇒ 2.3p – 10.1 = 6.5p – 4 – 0.01p

Convert the decimal into a fraction to get

⇒ (23/10)p – (101/10) = (65/10)p – 4 – (1/100)p

⇒ (23p – 101)/10 = (650p – 400 – p) /100

⇒ 230p – 1010 = 650p – 400 – p

As a result, the equation that has the same answer as 230p – 1010 = 650p – 400 – p.

What is the average rate of change from f(-1) to f(1)?Type the numerical value for your answer as a whole number, decimal or fractionMake sure answers are completely simplified

Answers

The average rate of change of the function is the average rate at which one quantity is changing with respect to another.

Average rate of change = (y2 - y1)/(x2 - x1)

y represents the output values and it is also called f(x)

x represents the input values

For the given interval,

for f(- 1), x = -1 and f(x) = 8

For f(1), x = 1, f(x) = 4

Average rate of change = (4 - 8)/1 - - 1) = - 4/(1 + 1) = - 4/2

Average rate of change = - 2

To find the area of a shape region:Find the area of the entire region:Fimd the area of the unshaded region(s)Subtract the area of the unshape region from the area of the entire region

Answers

IN order to find the area of the shaded region, proceed as follow:

calculate the area of the right triangle:

A = b·h/2

A = (21 yd)(34 yd)/2 = 357 yd²

next, calculate the area of the circle:

A' = π r²

A' = (3.1415)(7 yd)² = 153.93 yd²

next, subtract the area of the circle to the area of the rectangle:

AT = A - A' = 357 yd² - 153.93 yd²

AT = 203.07 yd²

Hence, the area of the shaded region is 203.07 yd²

The average velocities of the stone are: i) 12.96 m / s, ii) 13.20 m / s, iii) 13.20 m / s, iv) 13 m / s. The instantaneous velocity is approximately equal to 13 meters per second.

How to find the average velocity and the instantaneous velocity of a stone

The average velocity (u), in meters per second, is the change in the height (h), in meters, divided by the change in time (t), in seconds. And the instantaneous velocity (v), in meters per second, is equal to the average velocity when the change in time tends to zero.

a) Then, the average velocities are determined below:

Case i)

u = [f(1.05) - f(1)] / (1.05 - 1)

u = (18.748 - 18.1) / 0.05

u = 12.96 m / s

Case ii)

u = [f(1.01) - f(1)] / (1.01 - 1)

u = (18.232 - 18.1) / 0.01

u = 13.20 m / s

Case iii)

u = [f(1.005) - f(1)] / (1.005 - 1)

u = (18.166 - 18.1) / 0.005

u = 13.20 m / s

Case iv)

u = [f(1.001) - f(1)] / (1.001 - 1)

u = (18.113 - 18.1) / 0.001

u = 13 m / s

The fourth option offers the best estimation for the instantaneous velocity at t = 1 s. Then, the instantaneous velocity is approximately equal to 13 meters per second.

What is a confidence interval of proportions?

The bounds of a confidence interval of proportions is given according to the equation presented as follows:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which the parameters are described as follows:

[tex]\pi[/tex] is the sample proportion.z is the critical value of the distribution.n is the sample size, from which the estimate was built

The confidence level is of 90%, hence the critical value is z = 1.645, using a z-distribution calculator.

The values of the sample size and of the estimate are given as follows:

[tex]n = 447, \pi = \frac{169}{447} = 0.3781[/tex]

Hence the lower bound of the interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3781 - 1.645\sqrt{\frac{0.3781(0.6219)}{447}} = 0.3404[/tex]

The upper bound is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3781 + 1.645\sqrt{\frac{0.3781(0.6219)}{447}} = 0.4158[/tex]

As a percentage, the interval is given as follows: (34.04%, 41.58%).

The confidence interval does not contain 0.25, hence the true percentage would not be equal to 25%, contradicting the expectation.

An equation of line with a slope of 1/3 and containing the point (-4,7) is

In this question, we have been given

slope (m) = 1/3

We need to find an equation of a line with a slope of 1/3 and containing the point (-4,7)

Using the formula for the slope-point form of equation of line,

y - y1 = m(x - x1)

y - 7 = 1/3(x + 4)

y - 7 = (1/3)x + 4/3

y = (1/3)x + 4/3 + 7

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: 2x = 4 is an equation.

We have,

Let the number be K.

K thinks of a number, then doubles the number, and then multiplies the result by 3.

This can be written as:

(2 x k) = 2k ____(1)

3 x (2k) = 6k ____(2)

If her final number is 65 more than her original number can be written as:

6k = 65 + k _____(3)

From (3) we get,

6k = 65 + k

Subtract k on both sides.

6k - k = 65 + k - k

5k = 65

Divide both sides by 5.

5k / 5 = 65 / 5

k = 13

Thus,

Point 2 = (x2,y2) = (0,3)

Lines to be parallel must have the same slope, and to be perpendicular, they must have negative reciprocal slope.

None of the slopes are equal or negative reciprocal. SO, A and B are false-
