Answer:

The answer to your question is Al = 46.36 cm²; A = 222.36 cm²

Step-by-step explanation:

Data

length = 11 cm

width = 8 cm

height = 1.22 cm

Process

1.- Calculate the lateral area

Al = 2(length x height) + 2(width x height)

-Substitution

Al = 2(11 x 1.22) + 2(8 x 1.22)

-Simplification

Al = 26.84 + 19.52

-Result

Al = 46.36 cm²

2.- Calculate the base area

Ab = 2(11 x 8)

Ab = 176 cm²

3.- Surface area

A = 46.36 + 176

A = 222.36 cm²

john and ted have a reputation of being late to events. If john is late 20% of the time and ted is late 40% of the time what is

oee [108]

Answer:

The probability that they will both be on time is 12/25.

Step-by-step explanation:

John is late 20% of the time.

So, he is prompt 80% of the time.

Ted is late 40% of the time.

So, he is prompt 60% of the time.

Since, both the events are independent,

p(John be on time ∩ Ted be on time) = p(John be on time) × p(Ted be on time)

$= \frac{80}{100}$ × $\frac{60}{100}$

= 0.80 × 0.60

= 0.48 or 48%

$=\frac{12}{25}$

Hence, the probability that they will both be on time is 12/25.
