what is difference between 10 and 12?

The initial position is the starting point, and the final position is the endpoint.

We proceed to explain the initial and final position:

For example, if an object starts at the 2 meter mark (initial position) and moves 3 meters to the right, its final position would be at the 5 meter mark.

Answer:

92%

Step-by-step explanation:

The highest 5% of all IQs in the N(100, 15) Normal model are bounded by a value of 124.68, while the lowest 30% are bounded by a value of 92.64. The middle 80% of IQs are bounded by values between 80.77 and 119.23.

In the Normal model N(100, 15):

The highest 5% of all IQs are bounded by a z-score of 1.645, which corresponds to a value of 100 + (1.645 * 15) = 124.68. This means that an IQ of 124.68 or higher is in the top 5% of all IQs in this model.

The lowest 30% of the IQs are bounded by a z-score of -0.524, which corresponds to a value of 100 + (-0.524 * 15) = 92.64. This means that an IQ of 92.64 or lower is in the lowest 30% of all IQs in this model.

The middle 80% of the IQs are bounded by z-scores of -1.282 and 1.282, which correspond to values of 100 + (-1.282 * 15) = 80.77 and 100 + (1.282 * 15) = 119.23, respectively. This means that IQs falling between 80.77 and 119.23 are in the middle 80% of all IQs in this model.

The 1 1/2 cups divided by 2 is 0.75  cups

Division is the opposite of multiplication. If 3 groups of 4 are multiplied by 12, then dividing 12 into 3 equal groups yields 4 in each group when divided.

Dividend: The dividend is the number that is being divided in the division process.

Divisor: The number by which the dividend is being divided by is called the divisor.

Quotient: The quotient is a result obtained in the division process.

Remainder: Sometimes, we cannot divide things exactly. There may be a leftover number. That leftover number is called the remainder.

The relationship between these four parts can be expressed as follows:

Dividend = Divisor x Quotient + Remainder

The main purpose of sharing is to see how many equal groups form, or how many people belong to each group, when sharing equitably.

In the above example, to divide the 12 donuts into 3 similar groups, we need to place 4 donuts in each group. So dividing 12 by 3 gives 4.

The number outcomes in the sample space is option (3) 64

In mathematics, combination is a way of selecting a group of objects from a larger set, where the order in which the objects are selected does not matter.

The number of outcomes in the sample space can be calculated by finding the total number of possible combinations of genders for the six children.

For each child, there are two possible genders: male or female. Therefore, the number of possible outcomes for one child is 2.

To find the total number of outcomes for six children, we need to multiply the number of possible outcomes for each child together:

2 × 2 × 2 × 2 × 2 × 2 = 64

This is a word problem and the value of the unknown number is equal to 5.5.

We can write algebraically the second question as 3(x - 1).

Simplifying fully 15xy ÷ 15xy = 1/y

Word problems are mathematical problems which involves the use of ordinary words, instead of mathematical symbols.

Let us represent the unknown number with the letter x so that we derive the equation;

2x - 2 = 9

we add 2 from both sides of the equation

2x - 2 + 2 = 9 + 2

2x = 11

divide through by the coefficient of x which is 2

2x/2 = 11/2

x = 5.5.

Using x as the unknown, we can write the statement in the second question as 3(x - 1).

Suav deposits $450 every quarter into an account earning a quarterly interest rate of 2.225%. After 10 years, he would have $7,395 in the account to the nearest dollar.

The formula for calculating the future value (FV) of an investment is: FV = PV(1 + r/n)nt, where PV is the present value, r is the interest rate per period, n is the number of compounding periods per year, and t is the number of years.

In this problem, PV is $450, r is 2.225%, n is 4 (quarters in a year), and t is 10 years. Plugging these values into the formula gives us:

FV = 450(1 + 0.02225/4)4*10 = 450(1.0055625)40 = 450(2.7326) = $7,395

Therefore, after 10 years, Suav would have $7,395 in the account to the nearest dollar.

The linear equation y = -5x - 4 has a slope of -5 and a y-intercept of -4. Therefore, the correct graph should be a straight line with a slope of -5 and a y-intercept of -4.

Out of the four given options, the graph of a line that passes through the points (-1, 1) and (0, -4) represents the linear equation y = -5x - 4. To see why, we can use the two given points to find the slope of the line:

slope = (change in y) / (change in x) = (-4 - 1) / (0 - (-1)) = -5

The shape of the cross section is circle from the following option given.

A cylinder has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes.

When a cylinder is sliced parallel to its bases, the shape of the cross section will be a circle. This is because the bases of a cylinder are circular, and any plane that is parallel to the bases will intersect the cylinder in a circle of the same radius as the bases. Therefore, regardless of the position of the slice, the shape of the cross section will always be a circle.

An algebra over a field F is a vector space over F equipped with a bilinear operation called multiplication.

Let F be a field and let A be a vector space over F. An algebra over F is a triple (A, ×, 1) where × is a bilinear operation A x A -> A, and 1 is an element of A such that:

a × (b × c) = (a × b) × c for all a,b,c in A (associativity)

There exists an element 1 in A such that a × 1 = a = 1 × a for all a in A (existence of identity)

a × (b + c) = (a × b) + (a × c) and (a + b) × c = (a × c) + (b × c) for all a,b,c in A (distributivity)

a × b = b × a for all a,b in A if and only if A is commutative

The operation × is usually referred to as multiplication and the element 1 as the unit or identity element.

Answer:

15.585 is the radius of the cone

We need to add approximately 14.86 mL of water to 14 mL of 14% alcohol solution to reduce the concentration to 7%.

First, let's figure out how much alcohol is in the first 14 mL of the 14% alcohol solution.

Alcohol is equal to 0.14 x 14 (14%) times 14%, or 1.96 mL.

We need to add water so that the amount of alcohol stays the same while the overall volume grows in order to lower the concentration to 7%.

Assume that x mL of water needs to be added.

The volume of the solution will be (14 + x) mL with the addition of x mL of water, while the amount of alcohol will remain at 1.96 mL.

The equation for the ultimate concentration can be written as follows:

1.96 mL / (14 + x) mL = 0.07

When we find x and simplify, we get:

x = (1.96 mL / 0.07) - 14 mL

x ≈ 14.86mL

In order to lower the concentration to 7%, we must therefore add around 14.86 mL of water to 14 mL of 14% alcohol solution.

slides off the 0.86 m high counter and lands 1 m from the base. what was its initial speed ⇒ Ø = 56.87˚ beneath the horizontal

A. Suppose the horizontal component of the velocity is vx and the vertical is vy.

At first at t=0 (as the mug leaves the counter) the components are v0x and v0y.

v0y = 0 since the customer slides it horizontally so applied force is in the x component as it were.

The equations for horizontal and vertical shot movement are:

x = x0 + v0x t

y = y0 + v0y t - 1/2 g t^2 = y0 - 1/2 g t^2

Setting the beginning to be the end corner of the counter so that x0=0 and y0=0, thus:

x = v0x t

y = - 1/2 g t^2

Given esteem are: x=1.50m and y=-1.15m (y is negative since mug is going down)

1.50m = v0x t - - - - > v0x= 1.50/t

-1.15m = - (1/2) (9.81) t^2 - - - - - > t =0.4842 s

Working out for v0x:

v0x = 3.10 m/s

B. v0x is constant since there could be no other horizontal forces so, v0x=vx=3.10m/s

vy can be calculated from the recipe:

vy = v0y + at where a=-g (negative since going down)

vy = - gt = - 9.81 (0.4842)

vy = - 4.75 m/s

Presently to get the point beneath the horizontal, tan(90-Ø) = - vx/vy

tan(90-Ø )= 3.1/4.75
