Answer:

a. 7.4 cm

b. 22.2 cm²

Step-by-step explanation:

a. Apply Pythagorean theorem to find h.

c² = a² + b²

Where,

c = 8 cm

a = 3 cm

b = h cm = ?

Plug in the values

8² = 3² + h²

64 = 9 + h²

64 - 9 = h²

55 = h²

h = √55

h ≈ 7.4 cm

b. Area of the triangle = ½*bh

b = 6 cm

h = 7.4 cm

Area = ½*6*7.4

Area = 22.2 cm²

Kay is a student in Mrs. Hudson’s class. Assuming you know nothing else about Kay, what is the probability that Kay’s birthday w

Drupady [299]

Answer:

262/365

Step-by-step explanation:

So as you can see there is no more information aout Kay on her birthday, so the chances of her birthday being on a week day is given by the total number of the weekdays of the year between the total number of days in a year, so in 2019 there are 262 weekdays, divided by 365 you get the probability that Kay´s birthday falls on a weekday.

262/365=,7178=71,78%

So the probability of Kay´s brithday falling on a week day will be 71,72%
