The cost of four and three-fourths pounds of beef is $18.95.

Given,

Amount of beef purchased = 4 and 3/4th  pounds.

Cost of beef per pound = $3.99

We need to find how much four and three-fourths pounds of beef cost.

Find the cost of 1 pound of beef.

1 pound = $3.99

We can write four and three-fourths as:

= 4 3/4

= 19/4

Find the cost of 19/4 pounds of beef.

1 pound = $3.99

Multiplying by 19/4 on both sides.

19/4  x 1 pound = 19/4 x $3.99

19/4 pounds =$18.95

Thus the cost of four and three-fourths pounds of beef is $18.95.

I think the answer is KL, KJ, JL

Step-by-step explanation:

if treated as a right triangle (angle k is 92 degrees instead of 90) then JL would be the hypotenuse which would make it the longest. KL would be the shortest side (angle L acts as a 60-degree angle). this would mean KJ would be the middle length.

A. The measures of center shows that the mean is 41.3 and the median is 5.

B. The measure of variability shows that the range is 8 and IQR is 5.

C. Based on the given data, if you are interested in a smaller class size, Bay Side School would be a better choice for you.

Part A: For Bay Side School:

Mean: We sum up the class sizes and divide by the total number of classes.

Class sizes: 8, 6, 5, 8, 6, 5, 4, 2, 0, 5, 3, 2, 0, 0, 3

Sum = 8 + 6 + 5 + 8 + 6 + 5 + 4 + 2 + 0 + 5 + 3 + 2 + 0 + 0 + 3 = 62

Mean = 62 / 15 = 4.13

Class sizes in ascending order: 0, 0, 2, 2, 3, 3, 4, 5, 5, 5, 6, 6, 8, 8, 8

Median = (5 + 5) / 2 = 5

For Seaside School:

Mean: We sum up the class sizes and divide by the total number of classes.

Class sizes: 5, 8, 1, 0, 2, 5, 6, 8, 5, 7, 7, 8, 0, 6, 4

Sum = 5 + 8 + 1 + 0 + 2 + 5 + 6 + 8 + 5 + 7 + 7 + 8 + 0 + 6 + 4 = 72

Mean = 72 / 15 = 4.8

Median: We need to arrange the class sizes in ascending order and find the middle value.

Class sizes in ascending order: 0, 0, 1, 2, 4, 5, 5, 5, 6, 6, 7, 7, 8, 8, 8

Median = 6

Part B: In order to calculate the measures of variability, we will find the range and interquartile range (IQR) for each school's class sizes.

For Bay Side School:

Range: The range is the difference between the largest and smallest values.

Range = 8 - 0 = 8

IQR: The IQR is the difference between the third quartile (Q3) and the first quartile (Q1).

Q1 = median of the lower half of the data = (2 + 2) / 2 = 2

Q3 = median of the upper half of the data = (6 + 8) / 2 = 7

IQR = Q3 - Q1 = 7 - 2 = 5

For Seaside School:

Range: The range is the difference between the largest and smallest values.

Range = 8 - 0 = 8

IQR: The IQR is the difference between the third quartile (Q3) and the first quartile (Q1).

Q1 = median of the lower half of the data = (2 + 5) / 2 = 3.5

Q3 = median of the upper half of the data = (7 + 8) / 2 = 7.5

IQR = Q3 - Q1 = 7.5 - 3.5 = 4

C Based on the given data, if you are interested in a smaller class size, Bay Side School would be a better choice for you.

Considering both the measures of center and measures of variability, Bay Side School offers a smaller average class size (mean) and a smaller range of class sizes (IQR) compared to Seaside School. Therefore, if you prefer smaller class sizes, Bay Side School would be the better choice for you.

The two plans will cost the same when Lucy has driven average speed 550miles. ($55 + $0.50 x 550)= $330

Divide the overall distance traveled by the time period to find the average speed. An someone traveling at an average speed of 40 miles divided by 40 minutes, or 1 mile per minute, would be driving 20 miles north and then 20 miles south to arrive at the same location (60 mph)

The overall distance traveled by an object over the total amount of time is the thing's average speed. The average speed v of an object during a motion that covers a total distance of d and a total duration of t can be estimated using the formula v = d t.

(0.6*550)=$330

The difference between both the trip rate is .10$

and the difference between initial fee is 55$

so after 1 mile the difference is .10$

the 55$can be earn after

Therefore, the number of ways a student can work 7 out of 10 questions on the exam is 120, which corresponds to option (D).

The number of ways a student can work 7 out of 10 questions on an exam can be calculated using the concept of combinations.

The formula for combinations is given by:

C(n, k) = n! / (k!(n - k)!)

Where n is the total number of items and k is the number of items chosen.

In this case, the student is choosing 7 questions out of a total of 10, so we have:

C(10, 7) = 10! / (7!(10 - 7)!) = 10! / (7!3!)

Simplifying:

10! = 10 * 9 * 8 * 7!

3! = 3 * 2 * 1

C(10, 7) = (10 * 9 * 8 * 7!) / (7! * 3 * 2 * 1)

The 7! terms cancel out:

C(10, 7) = (10 * 9 * 8) / (3 * 2 * 1)

Answer:

  more than half are being used

Step-by-step explanation:

Perhaps easiest to understand is the most straightforward: figure the total number of seats and the number of seats being used. Check to see if that is more than half.

The 1 first-class carriage has usage of ...

  (3/8)(64 seats) = 24 seats.

The 6 standard carriages have usage of ...

  (7/13)(6 · 78 seats) = 252 seats.

The total number of seats used is ...

  24 + 252 = 276 . . . . seats used

__

The total number of seats on the train is ...

  1·64 +6·78 = 532 . . . . seats on the train

Half of the seats on the train will be ...

  532/2 = 266 seats . . . . half the seats

The 276 used seats are more than half of the total number. More than half the seats are being used.

_____

Alternate solution

Another way to look at this is to compare utilization to 1/2 in each carriage class.

  In first class 1/2 -3/8 = 1/8 of 64 seats = 8 seats fewer than 1/2 the seats are being used.

  In standard class, 7/13 -1/2 = 14/26 -13/26 = 1/26 of 78 seats = 3 seats more than 1/2 the seats are being used. There are 6 standard class carriages, so 6·3 = 18 more than half the seats in the standard-class carriages are being used.

This number is 10 more than the 8 under-utilized seats in first class, so more than half the train seats are being used.

The monthly interest rate you will be paying is approximately $2,583.33, and (b) the alternative loan is less attractive than the one from the car dealer, with the lender needing to charge an interest rate of approximately 2.31% to match the car dealer's rate.

(a) Calculation of the interest rate you will be paying every month:

Given:

The car will cost = $150,000

Amount to be paid upfront = 40%

Interest rate per annum = 2%

Loan tenure (no of years) = 5 years

Loan tenure (no of months) = 5 x 12 = 60 months

Using the formula to calculate the interest rate you will be paying every month:

Interest Rate = (Loan amount x interest rate per annum x Loan tenure (no of years) + loan amount) / Loan tenure (no of months)

Substituting the given values in the formula:

Interest Rate = (150000 x 2 x 5 / 100 + 150000) / 60

Interest Rate = (15000 + 150000) / 60

Interest Rate ≈ $2,583.33

Therefore, the interest rate that you will be paying every month is approximately $2,583.33.

(b) (i) You are able to secure financing for your car from another source. You will have to pay 3% per annum on this loan. The lender requires you to pay monthly for 5 years. Is this loan more attractive than the one from the car dealer?

Given:

Interest rate per annum = 3%

Loan tenure (no of years) = 5 years

Loan tenure (no of months) = 5 x 12 = 60 months

Using the formula to calculate the interest rate you will be paying every month:

Interest Rate = (Loan amount x interest rate per annum x Loan tenure (no of years) + loan amount) / Loan tenure (no of months)

Substituting the given values in the formula:

Interest Rate = (150000 x 3 x 5 / 100 + 150000) / 60

Interest Rate = (22500 + 150000) / 60

Interest Rate ≈ $2,916.67

The monthly payment amount is higher than the car dealer's, so this loan is not more attractive than the one from the car dealer.

(ii) Suppose the lender requires you to set aside $10,000 as security to be deposited with the lender until the loan matures and repayment is made. What interest rate must the lender charge for it to be equivalent to the interest rate charged by the car dealer?

Let x be the interest rate that the lender must charge.

Using the formula of compound interest, we can find the interest charged by the lender as follows:

150000(1 + x/12)^(60) - 10000 = 150000(1 + 0.02/12)^(60)

150000(1 + x/12)^(60) = 150000(1.0016667)^(60) + 10000

(1 + x/12)^(60) = (1.0016667)^(60) + 10000/150000

(1 + x/12)^(60) = (1.0016667)^(60) + 0.066667

Taking the natural logarithm on both sides:

60(x/12) = ln[(1.0016667)^(60) + 0.066667]

x ≈ 2.31%

Thus, the lender must charge approximately a 2.31% interest rate to be equivalent to the interest rate charged by the car dealer.

B ... An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles.

Step-by-step explanation:

Got it correct on Edge2020

The statement B is correct which states that the An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles.

Rotational symmetry, also known as radial symmetry in geometry, is the property a shape has when it looks the same after some rotation by a partial turn.

According to the statement

We have to find that the correct statement about the rotational symmetry for an isosceles triangle.

So, For this purpose, we know that the

From the given information:

Then from isosceles triangle,

An isosceles is a triangle that has two sides of equal length.

The isosceles theorem says that the angles opposite to the equal sides of a triangle are equal.

Thus, it also has two equal angles and one non equal angle. Thus,  it does not have all congruent angles.

The order of rotational symmetry of a  figure is the number of times we rotate up to 360° the figure such that it looks exactly the same as the original figure.

When we rotate the isosceles triangle up to 360° , only 1 time it looks exactly same as in the beginning because at each rotation the order of angles changes.

Therefore, The statement B is correct which states that the An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles.

The range of the function f(x) = log5x is (-∞, +∞).The function f(x) = log5x represents the logarithm base 5 of x. To determine the range of this function, we need to consider the possible values that the logarithm can take.

The range of the logarithm function y = log5x consists of all real numbers. The logarithm function is defined for positive real numbers, and as x approaches 0 from the positive side, the logarithm approaches negative infinity. As x increases, the logarithm function approaches positive infinity.

The range of the function is the set of all possible output values. In this case, the range consists of all real numbers that can be obtained by evaluating the logarithm

log5(�)log 5 (x) for �>0 x>0.

Since the base of the logarithm is 5, the function log5x will take on all real values from negative infinity to positive infinity. Therefore, the range of the function f(x) = log5x is (-∞, +∞).
