B.
rectangle
C.

D.

Answer:

Approximately 19 bags of sand will be required.

Step-by-step explanation:

The statement misses the drawing of the sandbox which I have attached here. We can find the dimensions mentioned in the picture.

Length of box = 6.5 feet

Width of box = 5 ft

Height of box = 1.5 ft

Calculating the volume = V = length x width x height = 6.5 x 5 x 1.5 = 48.75 cubic ft

As given in the question, one sand bag has 2.6 cubic ft of sand

No of bags required = 48.75 / 2.6 = 18.75

The test statistic is approximately 0.45.

To calculate the test statistic for testing the null hypothesis H₀:p = 0.55 against the alternative hypothesis H₁:p ≠ 0.55, you can use the formula for the z-test statistic:

z = (p' - p) / √(p(1-p)/n)

where:

p' = sample proportion

p = hypothesized proportion under the null hypothesis

n = sample size

In this case, the sample proportion is p' = 55/96 = 0.5729 (rounded to 4 decimal places), p = 0.55, and n = 96.

Now let's calculate the test statistic:

z = (0.5729 - 0.55) / √(0.55 × (1-0.55) / 96)

z = (0.0229) / √(0.55 × 0.45 / 96)

z = (0.0229) / √(0.2475 / 96)

z = (0.0229) / √0.002578125

z = (0.0229) / 0.050773383

z ≈ 0.4502 (rounded to 4 decimal places)

Therefore, the test statistic is approximately 0.45.

Parallelogram Theorem #1 Converse

Step-by-step explanation: : If each of the diagonals of a quadrilateral divide the quadrilateral into two congruent triangles, then the quadrilateral is a parallelogram. Parallelogram Theorem #2 Converse: If the opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram.

Parallelogram opposite sides converse. Therefore, option A is the correct answer.

A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.

Let the diagonals AC and BC intersect at O.

Consider, triangle BOC and triangle AOD

OA=OC (Shown in the figure)

∠AOD=∠BOC (Vertically opposite angles are equal)

BO=DO (Shown in the figure)

By SAS congruence theorem

triangle BOC and triangle AOD are congruent

So, by CPCT AD=BC

The NPV of the investment opportunity at a 6% interest rate is approximately $6,374. Taking into account the timing and value of the cash flows, it is advisable to take the opportunity.

The Net Present Value (NPV) of an investment opportunity calculates the present value of future cash flows discounted at a specific interest rate. Let's calculate the NPV at a 6% interest rate:

Year 1: Receive $500.

Year 2: Receive $1,500.

Year 10: Receive $10,000.

To find the NPV, we need to discount each cash flow back to its present value and sum them up:

NPV = (Cash flow at Year 1 / (1 + Interest rate)^1) + (Cash flow at Year 2 / (1 + Interest rate)^2) + (Cash flow at Year 10 / (1 + Interest rate)^10) - Initial investment

Plugging in the values, we get:

NPV = (500 / (1 + 0.06)^1) + (1500 / (1 + 0.06)^2) + (10000 / (1 + 0.06)^10) - 10000

≈ $6,374

Therefore, at a 6% interest rate, the NPV of the investment opportunity is approximately $6,374. Since the NPV is positive, it indicates that the investment is expected to generate a return greater than the cost of capital. Hence, it is advisable to take the opportunity.

(Note: The calculation for the NPV at 0% interest rate requires all future cash flows to be treated at their face value. Therefore, the NPV at a 0% interest rate would be equal to the sum of all future cash flows, which is $11,000 in this case.)

Answer:

Cost of each cord = $7.5

Step-by-step explanation:

Given:

Discount rate = 30% = 0.30

Amount save by Lisa = $9

Number of charger = 4

Find:

Cost of each cord

Computation:

Total cost of 4 charger =  Amount save by Lisa[1/Discount rate]

Total cost of 4 charger =  9[1/0.30]

Total cost of 4 charger =  $30

Cost of each cord = Total cost of 4 charger / Number of charger

Cost of each cord = $30 / 4

Cost of each cord = $7.5

To determine the percentage of the segment that should participate in the baseball camp in order to make a $1500 profit, we need to calculate the breakeven point and then find the corresponding percentage.

The breakeven point is the point where the revenue equals the total cost, resulting in zero profit. In this case, the breakeven point can be calculated by adding the fixed cost (TFC) to the variable cost per person multiplied by the number of participants.

Given that the price per participant is $80 and the variable cost per person is $5, we can set up the equation:

80x - (5x + 9000) = 0

Simplifying the equation, we have:

75x - 9000 = 0

75x = 9000

x ≈ 120

So, the breakeven point is approximately 120 participants.

To calculate the percentage, we need to divide the breakeven point (120) by the segment size (10000) and multiply by 100:

(120/10000) * 100 ≈ 1.2%

Therefore, the percentage of the segment that should participate in the baseball camp to make a $1500 profit is not exactly 1.2%, but it is closest to option D) about 1.4%.
