Answer:

I believe it's A=5 times 9 but since the triangle is special (3-4-5), it could be 12 times 5. Hope this kinda help :)

Suppose you just received a shipment of fourteen televisions. Three of the televisions are defective. If two televisions are ran

Cloud [144]

Answer with explanation:

Given : Total number of televisions received = 14

Number of defective televisions = 3

Probability of defective televisions : $\dfrac{3}{11}$

Now, If two televisions are randomly selected, then the probability that both televisions work.

$P(0)=(1-\frac{3}{11})^2\approx0.5289$

Hence, the probability that both televisions work is 0.5289 .

The probability at least one of the two televisions does not work will be :-

$P(X\geq1)=1-P(0)=1-0.5289\approx0.4711$

Hence, the probability at least one of the two televisions does not work is 0.4711.

An amusement park has two merry-go-rounds. The first merry-go-round has a platform with a diameter of 13 meters and the second m

Zinaida [17]

Answer:

The larger merry-go-round's platform is 151m² larger than the smaller merry-go-round's platform.

Explanation:

The area of a round shape is equal to the area of a circle.

The formula for the area of a circle is:

Area = π × radius²

Then, use that formula for each merry-go-round.

1. First merry-go-round

diameter = 13m

radius = diameter / 2 = 13m / 2 = 6.5m

area = π (6.5m)² = 3.14 × (6.5m)² = 132.665m²

2. Second merry-go-round

radius =9.5m

area = π (9.5m)² = 3.14 × (9.5m)² = 283.385‬m²

3. Difference of the areas

Larger area - smaller area = 283.385m² - 132.665m² = 150.72m²

Round to the nearest whole number: 151m².

Hence, the larger merry-go-round's platform is 151m² larger than the smaller merry-go-round's platform.
