Using the arrangements formula, it is found that there are 240 ways for the students to sit.

The number of possible arrangements of n elements is given by the factorial of n, that is:

[tex]A_n = n![/tex].

In this problem:

Hence:

T = 5 x 2! x 4! = 240.

Answer:

Let me know if this is not what you meant by rays, I can change it if needed.

Using sine rule, the value of x in the triangle formed by five roads is 53.36 degrees.

The value of x can be found using sine rule.

Therefore,

73.2 / sin 37°  = 97.6 / sin x

cross multiply

73.2 sin x = 97.6 sin 37°

73.2 sin x  = 97.6 × 0.60181502315

73.2 sin x  = 58.7371462596

divide both sides by 73.2

sin x = 58.7371462596 / 73.2

x = sin⁻¹ 0.80242003086

x = 53.3618236772

x = 53.36°

Therefore, the value of x is 53.36°

The value of the z is −2.1 then the probability P(z < −2.1) is 0.0179. Then the correct option is A.

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

If the value of the z is −2.1. Then the probability will be

P(z < −2.1) = 0.0179.

The cost of 1 shirt would be 10

you would need to multiply the cost of one shirt by the number of shirts bought (x)

The expression that can be used to determine the number of years that it would take to have a balance of $600 is In2 ÷ In[tex]e^{0.005}[/tex].

When an amount is compounded continously, it means that both the amount deposited and the interest already accrued increases in value continously over a period of time.

Time = In(FV/PV) ÷ In([tex]e^{0.005}[/tex]

The cost of one pair of earing will be £8.59.

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.

Given that four friends, each bought matching necklaces and two pairs of earrings the necklace was priced at 15.00 if the total bill for all 4 friends was 128.00.

The cost of one pair of earing will be,

£128-£15-£15-£15-£15= £68

Number of pairs of earing,

2x4=8 pairs of earrings

The cost of one pair of earrings is,

£68 / 8 = £8.50

Therefore, the cost of one pair of earing will be £8.59.

[tex]\\ \rm\dashrightarrow V2=88in^3[/tex]

Answer:

88 in³

Step-by-step explanation:

we are given that the volume V of a given mass of gas varies directly as the temperature T and inversely as the pressure P.

Condition-1:

The volume V of a given mass of gas varies directly as the temperature T , thus

[tex]V\propto T\\\implies V=kT[/tex]

Condition-1:

The volume V of a given mass of gas varies inversely as the pressure P, therefore,

[tex]V\propto 1/P\\\implies V=k\cdot 1/P[/tex]

combining 1 and 2 yields

[tex]V\propto k\cdot T/P[/tex]

Case-1:

To find:

Finding the constant of proportionality

[tex]341= k\cdot 310/10\\\implies k=341\times 10/310 \\ \implies \boxed{k=11}[/tex]

Case-1:

To find:

when:

Finding the volume:

[tex]V= 11\times 120/15\\\implies V=11\times 8 \\ \implies \boxed{V=88}[/tex]

x mL of the 35% saline solution contains 0.35x mL of salt.

10 mL of the 75% solution contains 0.75 • 10 mL = 7.5 mL of salt.

After mixing, the scientist would have a total volume of (x + 10) mL. We know its concentration is 40%, so it contains 0.40 (x + 10) mL of salt.

The total amount of salt before and after mixing must be the same, so

0.35x + 7.5 = 0.40 (x + 10)

Solve for x :

0.35x + 7.5 = 0.40x + 4.0

0.10x = 3.5

x = 35

The scientist used 35 mL of the 35% solution.

The equation for the base is that of a circle, so the cross sections will have a leg of length equal to the vertical distance between its halves.

x² + y² = 16   ⇒   y = ±√(16 - x²)

⇒   length = √(16 - x²) - (-√(16 - x²)) = 2 √(16 - x²)

Cross sections with thickness ∆x have a volume of

1/2 length² ∆x = 1/2 (2 √(16 - x²))² ∆x = (32 - 2x²) ∆x

since they are isosceles triangles and so their bases and heights are equal.

Then the total volume would be (D)

[tex]\displaystyle \int_{-4}^4 \frac12 \left(2 \sqrt{16-x^2}\right)^2 \, dx[/tex]
