Answer:

area ≈ 30.5 cm²

Step-by-step explanation:

the shaded area (A) is calculated as

A = area of circle - area of rectangle

= πr² - lb ( r is the radius of the circle )

given diameter = 10 cm then r = 10 cm ÷ 2 = 5 cm

A = (π × 5²) - (8 × 6)

= 25π - 48

≈ 30.5 cm² ( to the nearest tenth )

A jar of alphabet tiles contains 10 unique consonant tiles and 5 unique vowel tiles.

vladimir2022 [97]

Answer: Probability that 3 are consonants and 2 are vowels is 0.3996.

Step-by-step explanation:

Since we have given that

Number of unique consonant tiles = 10

Number of unique vowel tiles = 5

Total number of tiles = 10+5=15

we need to pick 5 tiles randomly,

So, Probability that 3 are consonants and 2 are vowels is given by

$\frac{^{10}C_3\times ^5C_2}{^{15}C_5}\\\\=\frac{\frac{10\times 9\times 8}{3\times 2\times 1}\times \frac{5\times 4}{2\times 1}}{\frac{15\times 14\times 13\times 12\times 11}{5\times 4\times 4\times 3\times 2\times 1}}\\\\=0.3996$

Hence, Probability that 3 are consonants and 2 are vowels is 0.3996.
