Ratio in X > Ratio in Z> Ratio in Y

lets assume: -

Total employees in Z = 50, Total Full Time = 30, Total Part Time = 20 Ratio in Z = 30/20 = 3/2

So, No. of Full time employees in X > 15(more than half) lets assume 18,

Also No. of part time employees in Y > 10(more than half). lets assume 12

So the no. of part time employees in X =8 Hence ratio in X = 18/8 = 9/4 >2

Similarly ratio in Y = 12/12 = 1

So Ratio in X > Ratio in Z > Ratio in Y

But we don't know the distribution of Full time Vs Part time employees in Z, X& Y

So lets flip to the no of F.T in Z = 20 and P.T = 30 Now Ratio in Z = 20/30 = 2/3

So No. F.T in X > 10 (Assume 12) so F.T in Y = 8

and P.T in Y > 15 (Assume 18) so P.T in X = 12

Ratio in X = 12/12 = 1

Ratio in Y = 8/18 = 4/9

Ratio in X = 2/3

Ratio in X > Ratio in Z> Ratio in Y

Sheba's initial horizontal velocity (Vx) is approximately 7.81 m/s, and her initial vertical velocity (Vy) is approximately 4.09 m/s.

To analyze Sheba's motion during dock diving, we can break down her initial velocity into horizontal and vertical components.

Given an initial speed of 8.72 m/s and an angle of 28 degrees, we can calculate the horizontal and vertical velocities using trigonometry.

The horizontal velocity (Vx) can be found using the cosine function:

Vx = V * cos(angle)

Vx = 8.72 m/s * cos(28 degrees)

Vx ≈ 7.81 m/s

The vertical velocity (Vy) can be determined using the sine function:

Vy = V * sin(angle)

Vy = 8.72 m/s * sin(28 degrees)

Vy ≈ 4.09 m/s

So, Sheba's initial horizontal velocity (Vx) is approximately 7.81 m/s, and her initial vertical velocity (Vy) is approximately 4.09 m/s.

If you received a gift of $10,000 3 years ago and you want to spend it in 3 years with interest rate is 4%, it will be worth $12,653.19. Option b is correct.

To calculate the future value of a present sum after a specified period, we can use the formula for compound interest:

Future Value = Present Value * (1 + Interest Rate)ᴺ

In this case, the present value is $10,000, the interest rate is 4% or 0.04, and the number of periods is 6 years because you received the gift 3 years ago and want to spend it in 3 years.

Using the formula:

Future Value = \(\$10,000 * (1 + 0.04)^6\)

Future Value = \(\$10,000 * (1.04)^6\)

Future Value = $10,000 * 1.1265319

Equation for G, representing the number of gallons of gas left after ‘T’ hours will be: G = 12 - 2T

Let G be the total number of gallons of gas left

And t be the time in hours

Since, car uses 2 gallons of gas in  1 hours

Therefore, total gallons of gas used in 4 hours will be 2 x 4 = 8 gallons

Total gallons of gas left after 4 hours = 4 gallons

Therefore, total gallons of gas before embarking on a road trip = 8 + 4 = 12 gallons

In general from the unitary method, number of gallons of gas used in time ‘T’ will be 2T

Therefore, Total gallons of gas left = (Total gallons of gas embarked on a road trip) - ( Total gallons of gas used in the trip at time ‘T’ )

From the above conclusions, we can write

G = 12 - 2T

Answer:

67,500 men

Step-by-step explanation:

Percent of children = 20% (.2)

30,000 x 5 = 150,000 (Total pop.)

150,000-30,000 = 120,000 (Pop. minus children)

.35 (Percent of women) x 150,000 =52,500

120,000-52,500 = 67,500

Answer:

67,500

Step-by-step explanation:

20 percent of the population is children. 45 percent is men. If children population is 30000, you multiply by 2 to get 40 percent. That means that if men were 40 percent, men population would be 60000. When you add another 5 percent to get 45 percent, it makes 67500 men.

Step-by-step explanation:

The head circumference of a newborn boy who marks the start of the 75th percentile is approximately 35.38 cm.

To find the head circumference of a newborn boy who marks the start of the 75th percentile, we need to first find the z-score corresponding to the 75th percentile using the standard normal distribution.

The z-score formula is

z = (x - μ) / σ

where x is the observed value, μ is the mean, and σ is the standard deviation.

To find the z-score that corresponds to the 75th percentile, we need to look up the z-score associated with a cumulative area of 0.75 under the standard normal distribution curve. This value can be found using a table or calculator and is approximately 0.674.

Now we can use the formula for the z-score to solve for the head circumference of a newborn boy at the 75th percentile

z = (x - μ) / σ

0.674 = (x - 34.5) / 1.3

0.674 × 1.3 = x - 34.5

0.8762 + 34.5 = x

x = 35.3762

x ≈ 35.38 cm

Step-by-step explanation:

you can just put in some values to check.

I actually used p =2 and q=3

the It will be

2^3-1 + 3^2-1 = 1 (mod 2×3)

2^2 +3^1 = 1 (mod 6)

4+3= 1 (mod6)

7= 1 (mod6)

which is true.

therefore p^(q-1) + q^( p-1) = 1 ( mod pq) is true

To show that p^(q-1) + q^(p-1) = 1 (mod pq), we can use Fermat's Little Theorem, which states that if p is a prime number and a is an integer not divisible by p, then a^(p-1) = 1 (mod p). Using this theorem, we can first show that p^(q-1) = 1 (mod q), since q is a prime number and p is not divisible by q. Similarly, we can show that q^(p-1) = 1 (mod p), since p is a prime number and q is not divisible by p.

Therefore, we can write:

p^(q-1) + q^(p-1) = 1 (mod q)
p^(q-1) + q^(p-1) = 1 (mod p)

By the Chinese Remainder Theorem, we can combine these two equations to obtain:

p^(q-1) + q^(p-1) = 1 (mod pq)

Thus, we have shown that p^(q-1) + q^(p-1) = 1 (mod pq).
We'll use Fermat's Little Theorem to show that p^(q-1) + q^(p-1) = 1 (mod pq).

Fermat's Little Theorem states that if p is a prime number and a is an integer not divisible by p, then:
a^(p-1) ≡ 1 (mod p)

Step 1: Apply Fermat's Little Theorem for p and q:
Since p and q are prime numbers, we have:
p^(q-1) ≡ 1 (mod q) and q^(p-1) ≡ 1 (mod p)

Step 2: Add the two congruences:
p^(q-1) + q^(p-1) ≡ 1 + 1 (mod lcm(p, q))

Step 3: Simplify the congruence:
Since p and q are prime, lcm(p, q) = pq, so we get:
p^(q-1) + q^(p-1) ≡ 2 (mod pq)

In your question, you've mentioned that the result should be 1 (mod pq), but based on Fermat's Little Theorem, the correct result is actually:
p^(q-1) + q^(p-1) ≡ 2 (mod pq)

The brick weighs 3.4 kilograms.

Quantities are values that can be measured or counted. They are typically represented by numerical values and units of measurement.

Let's assume that the weight of each brick is the same. Let's also denote the weight of each brick by "w" (in kilograms).

On one side of the scale, we have 9 bricks and 5 kilograms. So the total weight on this side is:

Total weight = (9 x w) + 5

On the other side of the scale, we have 4 bricks and 22 kilograms. So the total weight on this side is:

Total weight = (4 x w) + 22

Since the bricks on the scale are in balance, the total weight on both sides must be equal. Therefore, we can set the two expressions for total weight equal to each other and solve for w:

(9 x w) + 5 = (4 x w) + 22

Expanding and simplifying the equation, we get:

5 x w = 17

Therefore, the weight of each brick is:

w = 17 / 5

w = 3.4 kilograms

So each brick weighs 3.4 kilograms.
