A trapezoid has bases of lengths 13 cm and 17 cm. The

Vedmedyk [2.9K]

Answer:

135 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = $\frac{1}{2}$ h(a + b)

where h is the height and a, b the parallel bases

Here h = 9, a = 13 and b = 17 , thus

A = $\frac{1}{2}$ × 9 × (13 + 17)

= 0.5 × 9 × 30

= 135 cm²

pantera1 [17]

Answer:

It is an example of an empirical probability.

Step-by-step explanation:

The empirical probability, also called experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.

Theoretical probability is probability that is determined on the basis of reasoning.

It is evident that the probability in the question was arrived at after the outcome of 14 days of whether Jerry Gergich spilled his lunch on himself or not.

It's an actual result of an experiment, hence the 12/14 = 0.86 = 86% that he spills his lunch on himself tomorrow.

Hope this Helps!!!

Brand Number of Packets Cost

mash [69]

Brand 2 is the best value ⇒ B

Step-by-step explanation:

Let us write the Brand, Number of Packets and Cost

→ Brand : Number of Packets : Cost
→ 1 : 12 : $10.68
→ 2 : 16 : $9.44
→ 3 : 18 : $15.30
→ 4 : 24 : $21.84
→ 5 : 30 : $20.40

We need to find what brand is the best value

To find that let us find the price of each packet in each brand, by dividing the price of the brand by the number of the packets, the cheapest price is the best

∵ Brand 1 has 12 packets

∵ The price of Brand 1 is $10.68

∴ The price of each packet = 10.68 ÷ 12 = 0.89

∴ The price of each packet in Brand 1 is $0.89

∵ Brand 2 has 16 packets

∵ The price of Brand 2 is $9.44

∴ The price of each packet = 9.44 ÷ 16 = 0.59

∴ The price of each packet in Brand 2 is $0.59

∵ Brand 3 has 18 packets

∵ The price of Brand 3 is $15.30

∴ The price of each packet = 15.30 ÷ 18 = 0.85

∴ The price of each packet in Brand 3 is $0.85

∵ Brand 4 has 24 packets

∵ The price of Brand 4 is $21.84

∴ The price of each packet = 21.84 ÷ 24 = 0.91

∴ The price of each packet in Brand 4 is $0.91

∵ Brand 5 has 30 packets

∵ The price of Brand 5 is $20.40

∴ The price of each packet = 20.40 ÷ 30 = 0.68

∴ The price of each packet in Brand 5 is $0.68

∵ The least price of a packet is in Brand 2

∴ The cheapest price is Brand 2

Brand 2 is the best value
