140 birds in total 59 blue jays,68 black crows, 12 Red Robin’s and 1 cardinal what is the probability of the next bird being a blue jay

The probability of the next bird being a blue jay is 42.14%

Step-by-step explanation:

Given;

Total number of birds = 140

Number of blue jays = 59

Number of black crows = 68

Number of red robin's = 12

Number of cardinal = 1

The probability of the next bird being a blue jay is;

P = number of blue jay ÷ total number of birds

Substituting the values;

P = 59÷140

P = 0.4214

P = 42.14%

The probability of the next bird being a blue jay is 42.14%

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
