write the ratio as a ratio of whole numbers using fractional notation 30 to 45

Answer:

B (1, -3)

Step-by-step explanation:

Step 1:  Use the midpoint formula to find the coordinates of the endpoint:

Normally, we find the midpoint of a segment using the midpoint formula, which is given by:

M = (x1 + x2) / 2, (y1 + y2) / 2, where

Since we're solving for the coordinates of an endpoint, we can allow (-5, 7) to be our (x1, y1) point and plug in (-2, 2) for M to find (x2, y2), the coordinates of the endpoint B:

x-coordinate of B:

x-coordinate of midpoint = (x1 + x2) / 2

(-2 = (-5 + x2) / 2) * 2

(-4 = -5 + x2) + 5

1 = x2

Thus, the x-coordinate of the endpoint B is 1.

y-coordinate of B:

y-coordinate of midpoint = (y1 + y2) / 2

(2 = (7 + x2) / 2) * 2

(4 = 7 + x2) -7

-3 = y2

Thus, the y-coordinate of the endpoint B is -3.

Thus, the coordinates of the endpoint B are (1, -3).

Answer:

x=17.... I checked on mathaway and did it myself should be correct

Answer:

x=17

Step-by-step explanation:

2(x-7)=(x+3) divide both sides by two

2x-14 =(x+3) distribute

2x-14-x-3=0 substract x+3  

x-17=0 combine like terms

x=17 add 17 to both sides

Amanda will catch up to Ben after approximately 36 minutes.

To determine how long it will take for Amanda to catch up to Ben, we can set up an equation based on their respective speeds and the time difference.

the distance traveled by Ben is given by:

Distance = Speed * Time

Distance = 2 mi/h * (t + 1.5) h

the distance traveled by Amanda is given by:

Distance = Speed * Time

Distance = 7 mi/h * t h

equating both distances

2(t + 1.5) = 7t

2t + 3 = 7t

3 = 5t

t = 3/5

Therefore, it will take Amanda 3/5 of an hour (or 36 minutes) to catch up to Ben.

The lower limit is 69.4 inches and the upper limit is 70.6 inches.

The 90% confidence interval for the mean height of all U.S. males can be calculated using the formula:

\(CI = \bar{x} \pm\(\dfrac{\sigma}{\sqrt{n}}\)

Here \(\bar{x}\) is the sample mean, σ is the population standard deviation, n is the sample size, and z is the z-score corresponding to the desired confidence level.

For a 90% confidence level, z = 1.645.

Substitute the given values, and we get:

CI = 70 ± 1.645(1.5/√18)

CI = 70 ± 0.581

Lower limit = 70 - 0.581= 69.419

Upper limit = 70 + 0.581= 70.581

Therefore, the 90% confidence interval for the mean height of all U.S. males is [69.4, 70.6] inches.

The required simplified expression is: x² - 9/ 9x⁴ + 9x² for all x ≠ 0 or 3.

The given expression below is:

x² - 9 / (3x²)(3x²) + 9x²

To simplify the given expression, we must first distribute the terms on the numerator and denominator.

The numerator becomes x² - 9 and the denominator becomes (3x²)(3x²) + 9x².

Next, we must simplify the denominator by combining like terms. The denominator becomes 9x⁴ + 9x².

Finally, we can simplify the entire expression by dividing the numerator by the denominator.

This gives us the simplified expression: x² - 9/ 9x⁴ + 9x².

Note that this expression is not defined when x = 0 or x = 3, as it would result in a division by zero.

Thus, the final simplified expression is x² - 9/ 9x⁴ + 9x² for all x ≠ 0 or 3.

Answer:

x = 0

Step-by-step explanation:

I think you mean

\( \dfrac{x^2 + 3x}{x^3} \)

The only undefined values of x come from the denominator, x^3.

A denominator cannot equal zero since division by zero is undefined.

Therefore if x^3 equals zero, you get an un defined expression.

We let x^3 = 0 and solve for x to find the values of x that would cause an undefined expression.

x^3 = 0

Solve for x by taking the cubic root of both sides.

x = 0

Answer: x = 0

Each friend had originally 13 action figures before buying 11 more.

Given that there are 5 friends and each of them has x action figures in his or her collection. When they buy 11 more action figures, the total number of action figures they will have is 120.

a) We need to find an equation that models the problem. Let x be the original number of action figures that each friend had.

Therefore, the total number of action figures that each friend will have after purchasing 11 more is x + 11.

The total number of action figures will be 5(x + 11) = 5x + 55.

Now, according to the problem,5x + 55 = 120

This is our equation that models the problem.

b) We have to solve the equation 5x + 55 = 120 to find the original number of action figures, x, that each friend had before buying 11 more action figures.

5x + 55 = 120

5x = 120 - 55 (subtract 55 from both sides)

5x = 65x = 13

Therefore, each friend had originally 13 action figures before buying 11 more.

When 1,493,600 is divided by 8 the quotient is 186,700.

To divide 1,493,600 by 8, you can follow these steps:

We have to write down the dividend (1,493,600) and the divisor (8).

Now start with the largest place value in the dividend (the leftmost digit) and perform the division.

Divide 1 by 8. Since 1 is smaller than 8, you move to the next digit.

Bring down the next digit (4) and combine it with the previous quotient (0). This gives you 04.

Divide 4 by 8. Since 4 is smaller than 8, you move to the next digit.

Bring down the next digit (9) and combine it with the previous quotient (0). This gives you 09.

Divide 9 by 8. The quotient is 1, and the remainder is 1.

Bring down the next digit (3) and combine it with the remainder (1). This gives you 13.

Divide 13 by 8. The quotient is 1, and the remainder is 5.

Bring down the next digit (6) and combine it with the remainder (5). This gives you 56.

Divide 56 by 8. The quotient is 7, and there is no remainder.

Bring down the next digit (0) and combine it with the quotient (7). This gives you 70.

Divide 70 by 8. The quotient is 8, and there is no remainder.

There are no more digits to bring down, and the division is complete.

The quotient is the result of the division. In this case, 1,493,600 divided by 8 is equal to 186,700.

Therefore, the result of 1,493,600 ÷ 8 is 186,700.

The mean population in the U.S. is 2,068,548.

The median population in the U.S. is 1,565,659.

There is no mode in the dataset.

The standard deviation of the populations for the top twelve largest cities in the U.S. is 2,279,894.12.

To find the mean population, we need to sum up all the populations and divide by the total number of cities.

Mean = EF / n

Mean = 8,336,817 + 979,576 + 2,693,976 + 2,320,268 + 1,680,992 + 1,584,064 + 1,547,253 + 1,423,851 + 1,343,573 + 1,021,795 + 978,908 + 911,507

Mean = 24, 822,580 / 12

Mean =  2068548.33333

Mean =  2,068,548

Arranging populations in ascending order:

\(911,507, 978,908, 1,021,795, 1,343,573, 1,423,851, 1,547,253, \\1,584,064, 1,680,992, 2,320,268, 2,693,976, 8,336,817, 979,576\)

Median population = (1,547,253 + 1,584,064) / 2

Median population = 1,565,658.50.

The mode represents the value(s) that appear most frequently in the dataset. In this case, there is no single mode as each population value occurs only once. Therefore, we can say that there is no mode in the dataset of the top twelve largest cities in the U.S.

Standard Deviation:

\(\sqrt{(8,336,817 - 1,574,232)^2 + (979,576 - 1,574,232)^2 + (911,507 - 1,574,232)^2) / 12}\\\\\)

\(= \sqrt{62,333,273,003,930 / 12}\\= \sqrt{5,194,439,417,828.33} \\\\= 2,279,894.12\)
