Answer:

50/77

Step-by-step explanation:

(1÷2 3/4)+(1÷3 1/2)

2 3/4 is same as 11/44

1/2 is same as 7/2

so to divide fraction you have to flip the second number and multiply

so 1 times 4/11=4/11

and 1 times 2/7=2/7

4/11 +2/7=28/77+22/77=50/77

The height the anchor begins to drop is 17.5 m

Since a Naval Carrier dropped anchor off the coast. The massive anchor drops at 3.5 m/s and will be 52.5 meters under the surface of the water after 20 seconds.

Let

The total height the anchor drops is thus H = h + h'

Now, the total height the anchor drops H = vt where

So, equating both equations, we have

vt = h + h'

Making h subject of the formula, we have that

h = vt - h'

Given that

Substituting the values of the variables into the equation, we have that

h = vt - h'

h = 3.5 m/s × 20 s - 52.5 m

h = 70 m - 52.5 m

h = 17.5 m

So, the anchor drops 17.5 m

Answer:

Step-by-step explanation:

Answer:

m∠JKM = 63°

m∠MKL = 27°

Step-by-step explanation:

Since ∠JKL is a right angle. This means that by summing up both m∠JKM and m∠MKL will result in the same as ∠JKL figure. Thus, m∠JKM + m∠MKL = m∠JKL which is 90° by a right angle definition.

\(\displaystyle{\left(12x+3\right)+\left(6x-3\right) = 90}\)

Solve the equation for x:

\(\displaystyle{12x+3+6x-3 = 90}\\\\\displaystyle{18x=90}\\\\\displaystyle{x=5}\)

We know that x = 5. Next, we are going to substitute x = 5 in m∠JKM and m∠MKL. Thus,

m∠JKM = 12(5) + 3 = 60 - 3 = 63°

m∠MKL = 6(5) - 3 = 30 - 3 = 27°

The coefficient of variation (CV) is a measure of relative variability and is calculated by dividing the standard deviation by the mean, and then multiplying by 100 to express it as a percentage.

In this case, the mean weight is 340 grams, and the standard deviation is 5.2 grams.

CV = (Standard Deviation / Mean) * 100

CV = (5.2 / 340) * 100

CV ≈ 1.53%

Therefore, the correct answer is option B: 1.53%.

If you work 12 hours per day, the total earnings under your current wage structure would be:

8 hours * £20 per hour + 4 hours * £35 per hour = £160 + £140 = £300

Under the new job offer with a flat rate of £25 per hour, your total earnings would be:

12 hours * £25 per hour = £300

Therefore, both job options would result in the same total earnings of £300 per day.

The first 8 hours of work in your current job pay £20 per hour, while the remaining 4 hours pay £35 per hour. This means that the additional 4 hours you work beyond the initial 8 hours in your current job are compensated at a higher rate. However, since the new job offers a flat rate of £25 per hour for all 12 hours of work, the total earnings for both options become equal.

In this scenario, the decision between the two job offers would not be solely based on the wage rate but could consider other factors such as job stability, benefits, work environment, career prospects, and personal preferences.

If f(x)=2x²-5x-3 g(x)=2x²+5x+2 then (f/g)(x) = (x - 3) / (x + 2).

What is function?

In mathematics, a function is a relationship between two sets of elements, called the domain and the range, such that each element in the domain is associated with a unique element in the range.

To find (f/g)(x), we need to divide f(x) by g(x) as follows:

f(x) = 2x² - 5x - 3

g(x) = 2x² + 5x + 2

f(x) / g(x) = (2x² - 5x - 3) / (2x² + 5x + 2)

To simplify this expression, we can factor the numerator and denominator:

f(x) / g(x) = [(2x + 1)(x - 3)] / [(2x + 1)(x + 2)]

Now, we can cancel out the common factor of (2x + 1) from both the numerator and denominator:

f(x) / g(x) = (x - 3) / (x + 2)

Therefore, (f/g)(x) = (x - 3) / (x + 2).

Answer: y=\(-\frac{1}{10} x-7\)

Step-by-step explanation: The slope of a perpendicular line is always negative and the reciprocal (opposite fraction) of the regular slope so the slope would be \(-\frac{1}{10}\). If the line passes through (-10,-6) then the y intercept would be (0,-7) because every time x goes 10 right y goes down 1 because of the slope.

The relation's graph can be seen in the graphic at the bottom, where it is clear that it is   function.

The actual function can be specified using this "mapping" notation. Writing f:(x,y)x+y would allow us to define the above f(x, y). Real numbers are referred to as scalars to distinguish them from vectors. Each input is translated into a single output in a relation known as a function (input, output).

The horizontal axis is used for inputs, and the vertical axis is used for outputs. Here, we have the relationship shown below:

(-5,-1), (-4,1), (-3,3), (-1,5), (1,7) (1,7)

The figure below shows the graph of these points. Since there are no two points on the same vertical line, the relation is a function, as you can see.

For all samples of 5, there is a 0.05 probability that the sample mean would be higher than 22 pounds.

The assortment of bags weighs 19.7 pounds on average.

3.1 pounds is the standard deviation.

The sampling distribution theorem and the normal probability density function were both utilized.

The z-score formula is used to address problems involving samples with regularly distributed data.

Mean standard deviation, the z-score of a measure X is given by:

z = (x - μ) ÷ σ

The Z-score computes the number of standard deviations. The metric used is the average.

After calculating the Z-score, we look at the p-value associated with it in the z-score table.

This p-value represents the probability that the measure's value is smaller than X, or the percentage of X.

By taking away 1, we can determine the chance that the measure surpasses X.

If n is at least 30, the Central Limitation Theorem can also be applied to variables that are skewed.

No of the sample size, the sample mean will always be the same.

However, the standard error will change.

P(a > 22) denotes the likelihood that the sample means will be greater than 22.

The likelihood that they give it a chance will weigh more than 22 pounds is around 0.05 for all sampling of size 5.
