Answer:

5050

Step-by-step explanation:

Gauss has derived a formula to solve addition of arithmatic series to find the sum of the numbers from 1 to 100 as follows:

1 + 2 + 3 + 4 + … + 98 + 99 + 100

First he has splitted the numbers into two groups (1 to 50 and 51 to 100), then add these together vertically to get a sum of 101.

1 + 2 + 3 + 4 + 5 + … + 48 + 49 + 50

100 + 99 + 98 + 97 + 96 + … + 53 + 52 + 51

1 + 100 = 101

2 + 99 = 101

3 + 98 = 101

:

48 + 53 = 101

49 + 52 = 101

50 + 51 = 101

It was realized by him that final total will be fifty times of 101 means:

50(101) = 5050.

Based on this, Gauss has derived formula as:

The sequence of numbers (1, 2, 3, … , 100) is arithmetic and we are looking for the sum of this series of sequence. As per Gauss, the special formula derived by him can be used to find the sum of this series:

S is the sum of the series and n is the number of terms in the series, in present case, from 1 to 100, Hence

As per the Gauss formula, the sum of numbers from 1 to 100 will be 5050.

Answer:

the answer is 236.25

Step-by-step explanation:

The interest rate on annual basis on the given account should be considered as 0.9%.

Here the interest amount be

= Future value - principal

= $12,324 - $12,000

= $324

Now the interest rate be like

Interest = Principal * rate * time period

$324 = $12,000 * rate * 3/ 100

So, the rate be 0.9%.

Hence, The interest rate on annual basis on the given account should be considered as 0.9%.

Answer:

[tex]Height= 5cm[/tex]

Step-by-step explanation:

Given

Tank:

[tex]Base =20cm\ by\ 17cm[/tex]

[tex]Depth = 28cm[/tex]

Water:

[tex]Quantity = 1\frac{1}{4}L, 350mL, 100mL[/tex]

Required

Determine [tex]the\ height[/tex] of the water in the tank

First, we calculate the total volume of water added.

[tex]Quantity = 1\frac{1}{4}L+ 350mL + 100mL[/tex]

[tex]Quantity = 1.25L+ 350mL + 100mL[/tex]

Convert all units to Litres

[tex]Quantity = 1.25L+ 0.35L + 0.1L[/tex]

[tex]Quantity = 1.7L[/tex]

Convert to cm^3

[tex]Quantity = 1.7 * 1000cm^3[/tex]

[tex]Quantity = 1700cm^3[/tex]

The volume of the water in the tank is calculated as:

[tex]Volume =Base\ Area * Height[/tex]

i.e. the base area of the tank multiplied by the height of the water in the tank

[tex]Volume =20cm * 17cm* Height[/tex]

[tex]Volume =340cm^2* Height[/tex]

Since the above represents the quantity of water, we can substitute 1700cm^3 for Volume

[tex]1700cm^3=340cm^2* Height[/tex]

Make height the subject

[tex]Height= \frac{1700cm^3}{340cm^2}[/tex]

[tex]Height= \frac{1700cm}{340}[/tex]

[tex]Height= 5cm[/tex]

Step-by-step explanation:

The aim of this question is to find the probability that the student makes it to the second class prior to when the lecture commences.

Provided that A, B, and C are independent of each other from the full complete question.

Then; we want P(A + C < B)

So A [tex]\sim[/tex] N (2, 1.5)

B [tex]\sim[/tex] N (10, 1)

C [tex]\sim[/tex] N (6, 1)

P(A + C - B < 0)

Since they are normally distributed( i.e. A + C - B)

Then;

E(A + C -B) = E(A) + E(C) - (B)

E(A + C -B) = 2 - 10 + 6

E(A + C -B) =  -2

Var(A+C -B) = Var(A) + Var (B) + Var (C)

Var(A + C -B) = (1.5)² + (1)² + (1)²

Var(A + C -B) = 4.25

The standard deviation = [tex]\sqrt{4.25}[/tex]

The standard deviation = 2.06155

[tex]P(A+C-B) = p \Big (Z < \dfrac{0-(-2)}{2.06155} \Big )[/tex]

[tex]P(A+C-B) = p \Big (Z \le 0.97014 \Big )[/tex]

[tex]\mathbf{P(A+C-B) = 0.8340}[/tex]

Answer: The answer is two.

Step-by-step explanation: start by making a tree diagram and dividing all three numbers by two. Each number needs to end in whole numbers with no decimals or fractions. 1248 will be 624, 2024 will be 1012, and 1070 will be 535. Then as you keep dividing the only numbers that match together is two on all three as you will get 3 and 13 added to 1248, 11 and 23 added to 2024, and 5 and 107 to 1070. The only numbers that match are two so your answer is two.

The answer is below

Step-by-step explanation:

Given that the length of the plastic string is 3 3/4 feet = 15 / 4 feet.

Bracelets of 5/8 foot long is needed to be made. To determine the maximum number of bracelets that can be made; using the number line, 5/8 is subtracted repeated times from 15/4.

We can see that when 5/8 is subtracted 6 times from 15/4, the result is 0.

15/4 ÷ 5/8 = 6

Hence Tara can make 6 bracelets from the plastic sting.

Answer:

Since there is no initial condition, the exact value of v cannot be determined, but you can set the equation up for a general evaluation of the situation.

s = 1/2a^2*v+c

First you need to subtract c from both sides to get

s-c = 1/2a^2*v

then you can just divide both sides by 1/2a^2 to get v

(2(s-c))/a^2=v

when dividing a fraction, such as 1/2, make sure to keep in mind that you're really multiplying the flipped version, so that dividing by 1/2 means multiplying by 2.

Answer:

3.75%

Step-by-step explanation:

Principal , P= $800

Number of years, t = 2

Total Amount paid back(principal + simple interest) , A = $860

To obtain the interest rate on the loan :

We use the Relation :

A = P(1 + rt)

r = interest rate

860 = 800(1 + 2r)

860 / 800 = 1 + 2r

1.075 = 1 + 2r

1.075 - 1 = 2r

0.075 = 2r

r = 0.075 / 2

r = 0.0375

Hence, interest rate on loan = 0.0375 = (0.0375 * 100%) = 3.75%

As per the given ratio comparison, We can say that the Second job generates the most income and that position makes him $5 per hour.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, An employee working 40 hours per week earns a salary of $600 per week but gets a second job offer to work 40 hours per week, hourly at $20 an hour.

For the first job, we will calculate the ratio of the employee Salary to the working hours to compare with the salary of the Second job:

Since,

He makes $600 per week for working 40 hours

Thus,

His hourly salary = 600/40

His hourly salary will be $15.

For the second job, it is already mentioned that the employee gets $20 per hour for the same working hours.

therefore, the Second job generates the most income and that position makes him $5 per hour.
