Answer:

x = 50

Step-by-step explanation:

2485 ÷ x = 49 R 35

We know that 2485 ÷ x = 49 R 35, or 2485 ÷ x = 49 + 35

Step 1:

Now, I want to subtract 35 from the left side of the equation:

Step 2:

Now I want to find x. We can start by multiplying both sides by x, then dividing by the coefficient.

Answer:

29 ft x 58 ft

Step-by-step explanation:

Let x be the length of each side perpendicular to the wall, and y be the length of the side parallel to the wall.

The amount of wire available is:

\(116 = 2x+y\\y=116-2x\)

The area of the region is:

\(A=xy=x(116-2x)\\A(x)=116x-2x^2\)

The value of 'x' for which the derivate of the area function is zero will yield the maximum area:

\(A(x)=116x-2x^2\\A'(x) = 116-4x=0\\x=29\ ft\)

The value of y is:

\(y=116-2*29\\y=58\ ft\)

The dimensions of the region with the largest area are 29 ft x 58 ft.

Answer: x = 2

Intersecting Chords states:

Answer:

144.6ft

Step-by-step explanation:

Given

\(u = 45ft/s\) --- initial velocity

\(a = -7ft/s^2\) --- deceleration

Required

Distance traveled

To do this, we make use of:

\(v^2 = u^2 + 2as\)

Where

\(v = 0\) --- final velocity

So, we have:

\(0^2 = 45^2 - 2*7*s\)

\(0 = 2025 - 14s\)

Collect like terms

\(14s = 2025\)

Solve for s

\(s = \frac{2025}{14}\)

\(s = 144.6\)

The ratio of his role-playing games to all of his other games is 3:4.

An ordered pair of integers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you might express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. Ratios contrast two figures by typically dividing them. A/B would be your formula if you were comparing one data point (A) to another data point (B). This indicates that you are multiplying information A by information B. For instance, your ratio will be 5/10 if A is 5 and B is 10.

Here,

a) False. The percentage or proportion of top loaders that are faster than front loaders cannot be determined from the confidence interval. It merely offers a range of reasonable values for the mean cycle time difference.

b) False. The confidence interval does not indicate the likelihood that a specific event will occur once, but rather the likely range of the population parameter.

c) True. The confidence intervals for each sample would contain the real difference in mean cycle time in around 98% of the repeated random samples of top-loading and front-loading washers.

d) True. A confidence interval's confidence level indicates the likelihood that the interval contains the actual population parameter. Since there is a 98% degree of confidence in this situation, we would anticipate that 98% of the generated confidence intervals will contain the actual difference in mean cycle time.

e) False. The 98% confidence interval does not offer a probability or confidence level about a certain sample mean. Instead, it offers a range of logical estimates for the mean cycle time difference.

The approximate solution to the equation 1/x-1 = |x-2| after three iterations of successive approximation is x ≈ 5/2 or x ≈ 2.5.

To solve the equation 1/x-1 = |x-2| using three iterations of successive approximation, we will start with an initial guess and refine it using an iterative process.

Given that the equation involves absolute value, we will consider two cases:

Case 1: x - 2 ≥ 0

In this case, |x-2| simplifies to x-2, and the equation becomes 1/(x-1) = x-2.

Case 2: x - 2 < 0

In this case, |x-2| simplifies to -(x-2), and the equation becomes 1/(x-1) = -(x-2).

Now, let's perform the successive approximation:

Iteration 1:

Let's start with an initial guess, x = 2.

Case 1: When x - 2 ≥ 0,

1/(2-1) = 2-2,

1/1 = 0,

which is not true.

Case 2: When x - 2 < 0,

1/(2-1) = -(2-2),

1/1 = 0,

which is not true.

Since our initial guess did not satisfy the equation in either case, we need to choose a different initial guess.

Iteration 2:

Let's try x = 3.

Case 1: When x - 2 ≥ 0,

1/(3-1) = 3-2,

1/2 = 1,

which is not true.

Case 2: When x - 2 < 0,

1/(3-1) = -(3-2),

1/2 = -1,

which is not true.

Again, our guess did not satisfy the equation in either case.

Iteration 3:

Let's try x = 2.5.

Case 1: When x - 2 ≥ 0,

1/(2.5-1) = 2.5-2,

1/1.5 = 0.5,

which is true.

Case 2: When x - 2 < 0,

1/(2.5-1) = -(2.5-2),

1/1.5 = -0.5,

which is not true.

Our guess of x = 2.5 satisfies the equation in Case 1.

Therefore, the approximate solution to the equation 1/x-1 = |x-2| after three iterations of successive approximation is x ≈ 5/2 or x ≈ 2.5.

If a particular fruit's weights are normally distributed, with a mean of 598 grams and a standard deviation of 22 grams and I pick 9 fruits at random, then their mean weight will be greater than 605.29263 grams 16% of the time.

As per the question statement, a particular fruit's weights are normally distributed, with a mean of 598 grams and a standard deviation of 22 grams and I pick 9 fruits at random.

We are required to calculate their mean weight will be greater than how many grams for 16% of the time.

Given (μ = 598), (σ = 22), and (n = 9)

Therefore, the standard deviation of the distribution of sample, otherwise know as the standard error, will be [s = (sdp)/√(ss)]

Where, "s" is the standard error, "sdp" is the standard deviation of the population and "ss" is the sample size.

Therefore, [s = (22/√9) = (22/3) = 7.33...

Now, we need to look up the z-score for an area to the right of it being equal to (0.16) since we are concerned about (16%) times among the random selection, and [16% = (16/100) = 0.16]

That is, we need to look up the z-score for an area of [(1 - 0.16) = 0.84] to the left of it.

Hence, a z-score with an area of 0.84 to the left of it will be equal to 0.99445.

Now to find the raw score associated with this, we will have to use the formula to calculate z-score which goes as [(x - m)/s].

Where, "z" is the z-score, "x" is the raw score, "m" is the mean and "s" is the standard error.

Therefore, with a mean of 598 and a standard error of 7.333 and a z-score of 0.99445, applied to the above mentioned formula to calculate z-score, we get:

[0.99445 = (x - 598)/7.33]

Or, (x - 598) = (0.99445 * 7.33)

Or, (x - 598) = 7.29263

Or, x = (598 + 7.29263)

Or, [x = 605.29263]

That is, if I pick a sample of 9 fruits at random, then their mean weight will be greater than 605.29263 grams 16% of the time.

Answer:

30.4 minutes

Step-by-step explanation:

The tank already has 240L in it, so we need to fill 1000 - 240 = 760L of water.

Since the pump pumps 25L per minute, we can find how many minutes it takes to pump 760L.

760 / 25 = 30.4 minutes.

It will take 30.4 minutes to fill the tank completely.

Two or more expressions with an equal sign are defined as an equation.

Given that, The 1000 L tank contains 240 L of water, therefore, the free space in the tank is :

1000-240

= 760 L

The pump fills the tank at a rate of 25 L per minute.

Therefore, it can be represented as:

25 L = 1 minute

1 L = (1/25) minutes

760 L = (1/25)×760 minutes

760 L = 30.4 minutes.

Hence, it will take 30.4 minutes to fill the tank completely.

Answer:

the  price sold per kg to earn a profit of 20% is 7.2 kg

Step-by-step explanation:

The computation of the price sold per kg to earn a profit of 20% is shown below:

But before that the normal price per kg is

= 5.4  per kg × 100 ÷ 90

= 6 per kg

Now for 20% profit, the price per kg is

= 6 × (1 + 0.20)

= 6 + 1.2

= 7.2 kg

hence, the  price sold per kg to earn a profit of 20% is 7.2 kg

Step-by-step explanation:

120 is 120 spaces from zero

-130 is 130 spaces from zero

130+120=250

250 spaces from each other

Answer:

250

Step-by-step explanation:

You can think of this in different ways. Here are two ways.

1) The distance between any two points on the number line is the absolute value of the difference of the coordinates. Since you will take the absolute value of the difference, it makes no different in which order you do the subtraction.

For points on the number line with coordinates a and b,

distance = |a - b| = |b - a|

Here the coordinates are -130 and 120.

distance = |-130 - 120| = |-250| = 250

distance = |120 - (-130)| = |120 + 130| = |250| = 250

As you can see, the distance comes out the same no matter the order of the subtraction.

distance = 250

2) Just think of what the problem means and do a little calculation.

120 is a positive number, so it is located 120 units to the right of zero.

-130 is a negative number, so it is located 130 units to the left of zero.

To find the distance between the two numbers, think of starting at -130. You need to go 130 units right to reach zero. Then from zero you need to move another 120 units right to reach 120. The total distance is 130 + 120 which equals 250.

distance = 250
