The greatest number of 40-kilogram crates is 517.5.

From the question, we have

Weight of the crate = 40 kg

Greatest weight that the container can load = 25500 kilograms

Weight of the other shipments on the container = 4800 kg

So the greatest number of 40 kg crates = c

Therefore, the weight of the other shipment + weight of crate x number of crates ≤ greatest weight of the container

4800 + 40c ≤ 25500

40c ≤ 25500 - 4800

40c ≤ 20700

c ≤ 517.5

Hence, the greatest number of 40-kilogram crates is 517.5.

Subtraction:

Subtraction represents the operation of removing objects from a collection. The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5. Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers.

The letter "-" stands for subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation. A minuend is the first number in a subtraction process and is the number from which we subtract another integer in a subtraction phrase.

Step-by-step explanation:

the circle's area is approximately 2173.22 mm².We can find the radius of the circle by dividing the diameter by 2

what is  diameter ?

Diameter is a straight line passing through the center of a circle or sphere and connecting two points on the circumference. It is the longest chord of the circle.

In the given question,

The diameter of a circle is 52.6 millimeters.

We can find the radius of the circle by dividing the diameter by 2:

radius = diameter/2 = 52.6/2 = 26.3 mm

Now, we can use the formula for the area of a circle:

area = π × radius²

Plugging in the values we have:

area = 3.14 × 26.3² = 3.14 × 691.69 ≈ 2173.21 mm²

Rounding to the nearest hundredth, we get:

area ≈ 2173.21 ≈ 2173.22 mm²

Therefore, the circle's area is approximately 2173.22 mm².

If reserve rate decreases from 5% to 4%  then money supply of $50000

deposits increases .i.e bank can save $2000 and can lend $48000.

The reserve ratio is the percentage of reserves (or cash deposits) that a bank must keep and not lend out. The higher the reserve requirement, the less money a bank can potentially lend—but this extra cash also prevents a bank from failing and strengthens its balance sheet. Still, when the reserve ratio rises, monetary policy is considered contractionary, and when it falls, monetary policy is considered expansionary.

Given this, the reserve rate falls from 5% to 4%.

$50000 is the initial deposit.

If the reserve ratio is 5%, the bank must keep 50000*0.05 = $2500 in reserve and may make loans totaling 50000-2500=$47500.

If the reserve ratio is reduced to 4%, a bank with $50000 in deposits must save 50000*0.04 = $2000 before it can lend $48000.

Thus, if reserve ratio decreases then the money supply increases.

Step-by-step explanation:

You want the solution and some observations about it for the system of equations ...

The graph shows the lines cross at the point (x, y) = (2, 5).

The solution to the equations is (x, y) = (2, 5).

i) For x=2, the value of y in the first equation is ...

  y = 2(2) +1 = 4 +1 = 5

For x=2, the value of y in the second equation is ...

  y = -(2) +7 = -2 +7 = 5

ii) The values of y are the same, and match the value we found in part (a).

Additional comment

The purpose of the exercise is to get you to see that the value of x that is the solution makes both equations have the same value of y, and that is the value of y that is the solution.

The graph is a plot of the y-value for each x-value. Where the lines cross, the y-values are the same for that x-value. That point of intersection of the lines is the solution to the system of equations: the values of x and y satisfy both equations at that point.

The 99% confidence interval for the population proportion of printers that are used in small businesses, using the z-distribution, is of:

(0.2743, 0.5493)

A confidence interval of proportions has the bounds given by the equation presented next:

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

In which the variables used to calculated these bounds are listed as follows:

The confidence level is of 99%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.

(the critical value can be found either with the z-table or with a z-distribution calculator).

The sample size and the estimate are listed as follows:

[tex]n = 85, \pi = \frac{35}{85} = 0.4118[/tex]

The lower bound of the interval is obtained as follows:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4118 - 2.575\sqrt{\frac{0.4118(0.5882)}{85}} = 0.2743[/tex]

The upper bound of the interval is obtained as follows:

Probability is a branch of mathematics that deals with numerical descriptions of how likely an event or statement is to occur.

Answer:

x = 27.1  y = 62.9  x + y = 90

Explaination:

Let's say you have 2 complimentary angles, x and y

So x + y = 90

if x is 35.8 degrees less than the measure of a complementary angle, then x = y - 35.8

Putting this into our x + y = 90 equation, we get (y - 35.8) + y = 90

2y - 35.8 = 90

2y = 90 + 35.8

2y = 125.8

y = 125.8/2 = 62.9 degrees.

so x = 62.9 - 35.8 = 27.1 degrees.

Now , Value of E(x) can be calculated using the formula,

E(x) = [tex]\sum x_{i} P( x_{i} )[/tex]

      = (0)(0.027) + (1)(0.189) + (2)(0.441) + (3)(0.343)

E(x²) = [tex]\sum x_{i} ^{2} P(x_{i})[/tex]

        =  (0)²(0.027) + (1)²(0.189) + (2)²(0.441) + (3)²(0.343)
