The cost price of a wrist watch of 2500 at 25% gain what’s the selling price

Answer:

Step-by-step explanation:

sin^2 − sin^4 = cos^2 − cos^4

sin^2 (1-sin^2) = cos^2 − cos^4

sin^2 (cos^2) = cos^2 − cos^4

(1-cos^2) (cos^2) = cos^2 − cos^4

cos^2 − cos^4 = cos^2 − cos^4

9/10 - 4/10 =  (9-4) / 10 = 5/10 = 1/2

Answer:

9/10 - 4/10 = 5/10 (0.5) zero and a half.

Step-by-step explanation:

The denominators are the same so you only need to subract 4 from nine, you could even simplify it after by dividing the top of the fraction and the bottom by the same number. goodluck btw

Answer:

LN = 14

Step-by-step explanation:

In parallelogram diagonals bisect each other. That means that one diagonal cuts the other in half.

LJ is the diagonal and LN is a half of the diagonal.

Answer:

P(1 or 2) = 2/9

Step-by-step explanation:

OR means we add each probability

If it is 9-sided, I will assume the die will be numbered 1-9

Probability of getting a 1 in mathematical notation is:

P(1) = 1/9

Probability of getting 2:

P(2) = 1/9

We add their probabilities since we want to know if we get either 1 or 2

P(1) + P(2) = 1/9 + 1/9 = 2/9

If the question asked what the probability was of getting a 1 and a 2 by rolling the die twice, we would multiply the probabilities together

1/9 x 1/9 = 1/81

Answer:

From what we know about percentages and unit rates, the correct options are:

1) 100

2) 1

What is a percent?

Suppose we have an amount A, this would be the 100%.

If we want to know how much a quantity B represents, compared to A, we have:

A = 100%

B = x

where x is a percentage, to find the value of x we compute:

x = (B/A)*100%

While there is a dependence on A, we actually are comparing the term with 100 (because A represents a 100%), so the correct option is A: 100

  (b)  The area of the square pizza is larger

Step-by-step explanation:

The areas can be computed using the appropriate formulas, then compared.

__

  A = πr² . . . . . r = half the diameter

  A = π(5 in)² = 25π in² ≈ 78.5 in²

  A = s² . . . . . s is the side length

  A = (9 in)² = 81 in²

The area of the square pizza (81 in²) is larger than that of the circular pizza (78.5 in²).

1:If three pairs of sides of two triangles are equal in length, then the triangles are congruent. ASA (angle-side-angle): If two pairs of angles of two triangles are equal in measurement, and the included sides are equal in length, then the triangles are congruent. 2:All sides are equal in length. Diagonals bisect each other at a 90-degree angle. The sum of any two adjacent interior angles is 180 degrees. Opposite sides are equal and parallel to each other.3:Each pair of opposite sides is parallel, and adjacent sides are perpendicular. This means that every angle in a rectangle is a right (90∘) angle.

The area of the triangle with the given base and height where a = 4 and c = 2 is: 608 cm²

Area = 1/2(base)(height).

Given the parameters:

If a = 4 and c = 2, then:

Area = 1/2(base)(height) = 1/2(2ac²)(2ac² + 6)

Area = 1/2(2 × 4 × 2²)(2 × 4 × 2² + 6)

Area = 1/2(32)(38)

Area = 608 cm²

Answer:

Using the binomial distribution, it is found that

P(X > 3) = 0.0256

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, with p probability.

[tex]P(X = x) = C_{n, x} * p^{x} (1 - p)^{n- x }[/tex]

[tex]C_{n, x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n, x} = \frac{n!}{p!(n - x)!}[/tex]

P(X > 3) = P(X = 4)                         since it above next whole number above 3

In which

[tex]P(X = x) = C_{n, x} * p^{x} (1 - p)^{n- x }[/tex]

[tex]P(X = 4) = C_{4, 4} * (0.4)^{4} (1 - 0.4)^{4 - 4}\\C_{4, 4} = \frac{4!}{4!(4 - 4)!}\\\\P(X = 4) = \frac{4!}{4!(0)!} * (0.4)^{4} (0.6)^{0}\\[/tex]

Then

P(X > 3) = P(X = 4)

P(X > 3) = 0.0256

Answer:

3:2.

Step-by-step explanation:

They have 15 - 6 = 9 problems to do, so it is:

9:6

Answer:

9/15

Step-by-step explanation:

15 - 6 = 9 as a fraction would be 9 meaning what is left and 15 as meaning how much they started with so it is 9/15 also called 9 over 15

The proofing of Fermat's last theorem shows that y = a² - b², z = a² + b² and x = 2ab.

The equation x² + y² = z². We can assume that x, y, and z are positive and relatively prime. Suppose that x is even. Then:

(z - y/2)(z + y/2) = (x/2)²

Hence,

(z - y)/2 = b²

(z + y)/2 = a²

Then, y = a² - b², z = a² + b² and x = 2ab.

Answer:

  A.  200 packages

Step-by-step explanation:

The number of packages per roll can be found by dividing the length of a roll by the length of tape needed for each package.

__

For each package:

  (2.375 in/piece)×(4 piece/package) = 9.5 in/package

Per roll:

  (1900 in/roll) / (9.5 in/package) = (1900/9.5) packages/roll

  = 200 packages/roll

The machine can seal 200 packages with a roll of tape 1900 inches long.

There are a total of 11 chocolates in the box.

The probability of picking milk chocolate first is 4/11.

Now that you eat one, there are 10 chocolates in the box.

The probability of picking a dark chocolate second is 7/10.

This is a compound probability problem, so multiply the two probabilities together.

4/11 x 7/10 = 28/110

Answer:

x = 2√5

Step-by-step explanation:

Isosceles right angle triangles have two congruent sides ( for more reference , kindly check the attached image ) making it a special 45-45-90 degree triangle.

Special triangles have simple easy rules to help identify the lengths of the other sides lengths. For the 45-45-90 degree triangle, the hypotenuse (longest side) is equal to the value of the triangles leg(shorter sides) times √2 ( for more reference kindly check the other attached image )

Here, the value of the leg it equal to √10

If the value of the hypotenuse (x) = leg × √2

Then the value of x = √10 × √2

x = √10 × √2 = √(10 × 2) = √20

==> simplify radical

x = 2√5

Answer:

Step-by-step explanation:

Given :

f(x) = x − 3

g(x) = x² − x

Note : (f+g)(x) = f(x) + g(x)

then

(f+g)(2) = f(2) + g(2)

           = (2 - 3) + (2² - 2)

           = -1  +  2

           = 1

another method:

(f+g)(x) = f(x) + g(x) =  x − 3 + x² − x = x² - 3

then

(f+g)(2) = 2² - 3 = 4 - 3 = 1

Step-by-step explanation:

Elena should go to the south market because there is 0.52 probability of both cherries and asparagus being available.

The table is given as:

                   North market     South market

Cherries          0.96                   0.8

Asparagus       0.5                   0.65

The probability of buying both produce at both markets is calculated as:

P(North) = 0.96 * 0.5 = 0.48

P(South) = 0.8 * 0.65 = 0.52

0.52 is greater than 0.48

Hence, Elena should go to the south market because there is 0.52 probability of both cherries and asparagus being available.
