(115) the product of integers x, y, and z is even. is z even?

1 answer:

5 0

1. X/Y = Z

if x = 6, y = 2, then z = 3, not even

if x = 6, y = 3, then z = 2, even

2. Z=XY 

so (z)^2 = 2*k (because x*y*z = 2k, where k is an integer)

Sufficient, as if square of an integer is even ,then the integer is even

What is the area of the white border?

Lina20 [59]

Answer:

$A_{white} = 119\ cm^2$

Step-by-step explanation:

Step 1: Determine the area of the black area

$A = l * w$

$A = 8\ cm * 2\ cm$

$A = 16\ cm^2$

Step 2: Determine the area of the entire white and black area

$A = l * w$

$A = 9\ cm * 15\ cm$

$A = 135\ cm^2$

Step 3: Determine the difference to just get the white area

$A_{white} = 135\ cm^2 - 16\ cm^2$

$A_{white} = 119\ cm^2$

Answer: $A_{white} = 119\ cm^2$

Giving a test to a group of students, the grades and gender are summarized below

Anna007 [38]

Answer:

46/ 67

Step-by-step explanation:

The numbers of students irrespective of grades is;

The sum of the last roll of numbers:

10+24+ 33+ 67 = 134

The number of males irrespective of grades is the sum of the numbers in the male row ;

7 +20+ 14 +41= 82

The numbers of students with grade A is the first column at the last row and is 10;

Hence;

the probability that the student was male OR got an 'A' is

the probability that the student was male plus the probability that he/she got an 'A'.

The probability that it's a male is ;

Number of males/ total number of students

=82/134

The probability that he got an A is;

The number of students that got A/ the total number of students;

10/134

Hence

the probability that the student was male OR got an 'A' is;

82/ 134 + 10/134 = 92/134 = 46/ 67

Find the value of k. Then find the angle measures of the polygon

pochemuha

Answer:

45° + 2k + k = 180°

=> 45 + 3k = 180

=> 3k = 180 – 45

=> k = 135/3

=> k = 45

other two angles :-

2k = 2×45 = 90°

k = 45°
