Lets discern the infomation:

number_men = 165*0.6 = 99

so there are 99 men

non_fiction = 165 * 0.4 = 66

so 66 authors write non-fiction.

men writing non-fiction are 40, so 59 men write fiction, and 26 women write non-fiction.

probability of author non-fiction or man?
non-fiction: 40 men + 26 women = 66 total
man writers = 99

so in total 99 man + 26 women = 115 authors

hence the probability is:
115/165 = 69.6%

What are all the variables of x y and z ?
Anettt [7]

Answer:

x°=96°

y°=88°

z°=151°

Step-by-step explanation:

55°+29°+×°=180°

×°=96°

96°+55°=z°

z°=151

then let variable A° be one of the inner angle of the triangle

A°+z°=180°

A°+151°=180°

A°=29°

finally adding all the inner angles will give us 180°

96°+y°-13°+29=180°

y°=88°

Write the roman numeral of the Olympics Games that follow the 28th games
bogdanovich [222]

The  Olympics Games that follow the 28th games will be "XXIX Games."

The Olympic Games that follow the 28th Olympic games is the 29th Olympic Games.

29 in Roman numerals is:

= XXVIII

An X in Roman numerals is 10 so the first two Xs are to signify "20."

An "IX" in Roman numerals is "9" which will then take the number to 29.

It will therefore be the "XXIX Olympic Games."

In conclusion, the number 29 is XXIX in Roman numerals so Olympic Games after the 28th games will be "XXIX Games."

About two times greater.

4 times 10 minus 6 equals 34.

77 minus 34 is 43

43 minus 34 is 9.

34 can only be put into 77 two times
