Answer:

Perimeter of a square that measure 5.35 on one side is, 21.4 cm

Step-by-step explanation:

Perimeter of a square is the total length of the boundary of a square.

It is given by:

$P = 4a$ ......[1] where

P represents the perimeter of square,

a represents the side of square.

Given: a = 5.35 cm

Substitute this value in [1] we get;

P = 4(5.35) = 21.4 cm

therefore, the perimeter of a square is, 21.4 cm

Answer:

$(x-2)^{2} + (y+3)^{2} = 4$

Step-by-step explanation:

Formula

$Centre (a,b) \\Radius r(x-a)^{2} + (y-b)^{2} = r^{2}\\\\Centre (2, -3) \\Radius 2(x-(2))^{2} + (y-(-3))^{2} = 2^{2}\\(x-2)^{2} + (y+3)^{2} = 4$

A coffee shop collected the following information regarding purchases from 110 of its customers 59 purchased coffee 39 purchased

Andrej [43]

Answer:

Let X be the number of customer purchased coffee

Let Y be the number of customer purchased donuts

Then $X\cap Y$ is the number of customer purchased both coffee and donuts

$X\cup Y$ is the number of customer purchased both coffee or donuts

The Number of customers purchased only Coffee:

Number of customers purchased only donuts =n(X -Y)

$n( X -Y) = n(X) - n(X \cap Y)$

n(X-Y) = 59 -16

n(Y - X) = 43

The Number of customers purchased only donuts:

Number of customers purchased only donuts =n(Y -X)

$n(Y - X) = n(Y) - n(X \cap Y)$

n(Y - X) = 39 -16

n(Y - X) = 23

The Number of customers did not purchase either of these items:

Number of customers did not purchase either of these items = $n(X\cup Y)^{\prime}$

First lets find $n(X\cup Y)$

$n(X\cup Y) = n(X) + n(Y) - n( X \cap Y)$

$n(X\cup Y) = 59 + 39 - 16$

$n(X\cup Y) = 82$

$n(X\cup Y)^{\prime}$ = $110 - n(X\cup Y)$ = 28
