Answer:

77.4 (nearest tenth)

Step-by-step explanation:

76 is 100% of the original number.

To increase a number by 1.8% it will be 100% + 1.8% = 101.8% of the original number.

[tex]\begin{aligned}\implies \sf 101.8\%\; of\; 76&=\sf \dfrac{101.8}{100} \times 76\\\\&=\sf \dfrac{101.8 \times 76}{100}\\\\&=\sf \dfrac{7736.8}{100}\\\\&=\sf 77.368\\\\&=\sf 77.4\; (nearest\;tenth)\end{aligned}[/tex]

Therefore, the result when the number 76 is increased by 1.8% is 77.4 to the nearest tenth.

The compound interest is $348,966.97 and the future value is $464,966.97.

percentage, a relative value indicating hundredth parts of any quantity.

We can use the formula for compound interest to calculate the future value of the investment:

[tex]FV=P(a1+r/n)^{nt}[/tex]

where:

P = the principal amount (the initial investment)$116,000

r = the annual interest rate (as a decimal)=0.0429

n = the number of times the interest is compounded per year=52

t = the number of years=34

Plugging in these values, we get:

FV = $116,000(1 + 0.0429/52)¹⁷⁶⁸

FV = $464,966.97

So the future value of the investment after 34 years is $464,966.97.

Compound interest = $464,966.97 - $116,000 = $348,966.97

Therefore, the compound interest is $348,966.97 and the future value is $464,966.97.

The average rate of change of the function between x = a and x = a + h is -6

The slope is -6

From the question, we have the following parameters that can be used in our computation:

g(x) = -6x + 1

The interval is given as

x = a and x = a + h

So, we have

g(a) = -6a + 1

g(a + h) = -6(a + h) + 1

This gives

g(a) = -6a + 1

g(a + h) = -6a + -6h + 1

Subtract the functions

g(a) = -6a + 1

g(a + h) = -6a + -6h + 1

g(a) - g(a + h) = -6h

The average rate is then calcualated as

Average = [g(a) - g(a + h)]/(a - a - h)

Average = (-6h)/-h

original = 100% = 1

original + 8% increase = 1 + 0.08 = 1.08

Answer: Around 9,284 books.

Step-by-step explanation:

   First, we will find how large this sample is by using addition.

753 + 74 + 30 = 857

   Next, since we are looking for the expected minor or major damage, we will find the number of books from this sample that meet the requirements.

74 + 30 = 104

   Now, we will find the percentage of this sample that meets the criteria.

(104 / 857) * 100 ≈ 12.13536%

   Lastly, we will use this value to determine how many books in the collection are likely to have minor or major damage.

76,500 * 12.13536% = 9,283.55 ≈ 9,284 books

Answer:

Mrs. Parker should expect around 9284 books in the library's collection to have minor damage or major damage.

Step-by-step explanation:

To calculate the expected number of books with minor or major damage in the entire collection, we can scale up the sample proportion to the size of the full collection.

First, let's find the proportion of books with minor or major damage in the sample:

Proportion = (74 + 30) / (753 + 74 + 30) = 104 / 857 = 0.1214

Next, we'll scale up this proportion to the size of the full collection:

expected number of books with minor or major damage = proportion * 76,500 = 0.1214 * 76,500 = 9283.5472578763

Finally, we round the result to the nearest whole number:

expected number of books with minor or major damage = round(9283.5472578763 ) = 9284

So, Mrs. Parker should expect around 9284 books in the library's collection to have minor damage or major damage.

Answer:

0.4850 knots.

Step-by-step explanation:

To convert the speed of the California Current from centimeters per second to knots, we can use the conversion factor of 1 knot = 0.514444444 cm/s.

So, 0.25 cm/s * 1 knot / 0.514444444 cm/s = 0.4850 knots.

Therefore, the California Current moves at a speed of approximately 0.4850 knots.

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

What is a cost function?

For some fixed factor prices, the cost function calculates the lowest cost of generating a specified level of output. The economic potential of a corporation is described by the cost function.

According to the cost function, the optimal assignment in order to minimise the total cost is by assigning:

Job J1 to machine M2 having a cost of 11

Job J2 to machine M3 having a cost of 12

Job J3 to machine M1 having a cost of 14

Job J4 to machine M4 having a cost of 11
