The range of the data divided by four gives the standard deviation, which is approximately.

The range of the data divided by four gives the standard deviation, which is approximately. Simply put, that's it. To determine the range, find the highest value—the maximum—and deduct the lowest—the minimum. The range should then be divided by 4.

The range rule states that a sample's standard deviation is roughly equal to one-fourth of the data range.

In order to calculate the standard deviation, we must first determine the mean, take this mean away from each data point, square the differences, add them, divide by one less than the number of data points, and (at the very end) take the square root. The range rule, however, only needs one division and one subtraction.

The time taken for the rocket to reach its maximum height as required in the task content is; 2.25 seconds.

The maximum height reached by the toy rocket is; 88 feet.

It follows from the task content that the maximum height reached by the rocket is to be determined.

The given function is; h (t) = -16 t² + 72t + 7.

Since it follows from evaluation that; at maximum height, the rate of change of height to time is equal to 0.

Therefore; at maximum height;

h'(t) = 0

h'(t) = -32t + 72 = 0

-32t = -72

t = -72/-32

t = 2.25 seconds.

Therefore, the time taken for the rocket to reach its maximum height is; 2.25 seconds.

Also, the maximum height reached by the rocket is at; h (2.25);

h(2.25) = -16(2.25)² + 72 (2.25) + 7

= -81 + 162 + 7

= 88.

The maximum height reached is; 88 feet.

What is contract?

An agreement between parties that results in legal duties for both parties is known as a contract. Mutual consent, demonstrated by a valid offer and acceptance, sufficient consideration, capability, and legality are the fundamental components needed for the agreement to be a legally enforceable contract.

Provided data from the question;

Futures contract to buy in euros = €62,500

Future contract to buy in dollar = $93,750 ( €62,500 × $1.50)

Initial performance of bond = $1,500

Maintenance level = $500

To determine the settle price at which you get a demand for additional funds to be posted =

Future contract to buy in dollar - (initial bond performance - maintenance level) ÷ future contract to in euros

$93,750 - ($1,500 - $500)

= $93,750 - $1,000

$92,750 ÷ €62,500

The procedure to calculate the p-value from z-score depends on one of two choices: one-tailed (which may be Left-tailed or Right-tailed) or two-tailed tests.

A z-table, otherwise termed the standard normal table, provides the area under the curve to the left of a z-score.

The technique for using z-tables to find p-values depends on the test being carried out; which may be; one- or two-tailed test.

For one-tailed tests, the directionality is also a factor.

It therefore follows that;

For a Left-tailed z-test: the p-value = Φ(Zscore)

For a Right-tailed z-test: the p-value = 1 - Φ(z-score).

For a Two-tailed z-test: the p-value = 2 * Φ(−|z-score|).

Answer: 1/(x+2)

Step-by-step explanation:

[tex]\frac{x+4}{x^2+6x+8}\\[/tex]

[tex]\frac{x+4}{(x+2)(x+4)}[/tex]

the x+4 cancel each other so we are left with 1/(x+2)

if the main question was how to foil the denominator x2 + 6x + 8, i can quickly explain that.

x2 + 6x + 8

a2 + bx + c

first step is to multiply the first variable with that last or a * c which in this case would give 1 * 8 = 8

the next step would be to look at the middle number which is b, in our case 6.

so then you look for two number that can multiply to to give 8 as well as add up to 6. With easy guessing one will come up with 4 and 2.

with this values you can impute them directly into the equation as

x^2 +4x +2x+ 8

split the equation then factor

(x^2 +4x) (2x+ 8)

x(x+4) 2(x+4) note that the factored equation must always be the same in the bracket. If they are not the same then you have made a mistake somewhere across the line.

We can rewrite the equation of the circle as:

So the center is (-4, -4) and the radius is 12 units.

For a circle of radius R and center (a, b) the equation is:

(x - a)^2 + (y - b)^2 = R^2

Here we have the equation:

x^2 + 8x + y^2 + 8y - 112 = 0

We can complete squares to get:

(x^2 + 8x) + (y^2 + 8y) - 112 = 0

(x^2 + 2*4*x + 4^2) +  (y^2 + 8y + 4^2) - 4^2 - 4^2 - 112 = 0

(x + 4)^2 + (y + 4)^2 = 112 + 16 +  16 = 144

Analysis of variance is a collection of statistical models and the estimation procedures that go with them that are used to analyze the differences between means. Ronald Fisher, a statistician, invented ANOVA. The ANOVA test compares more than two groups at the same time to see if there is a relationship between them.

If the null hypothesis is correct, you should expect F to be close to 1.0 most of the time. A high F ratio indicates that the variation among group means is greater than would be expected by chance.
