4 0

Answer:

p(A) = 0.55

p(b) = 0.45

Step-by-step explanation:

Experimental probability = \frac{Number of favorable outcomes}{Total number of outcomes}

total students = 55 + 45   ⇒ 100

let A be the probability that students brought lunch from house = \frac{55}{100} ⇒ 0.55

let B be the probability that students order school lunch = \frac{45}{100} ⇒ 0.45

A line is written in standard form Ax + By = 0, where A and B are not
cricket20 [7]

Answer:

A point that must lie on this line is the origin (0,0)

Step-by-step explanation:

we know that

The equation of the line in standard form is equal to

Ax+By=C

where

A is a positive integer

B and C are integer

In this problem

C=0

so

Ax+By=0

That means, that the line represent a proportional relationship between the variables x and y

Remember that in a proportional relationship the line passes through the origin

therefore

A point that must lie on this line is the origin (0,0)

A piece of wire is 8/9 meter long broke into two pieces. One piece is 2/3 meter long. How long is the other?
Genrish500 [490]

Answer:

<h2><em><u>2/9 is the answer.</u></em></h2>

Step-by-step explanation:

<em><u>1. First, make an equation.</u></em>

<em><u>Given:</u></em>

8/9 = length of wire

2/3 = length of a part of the wire

E = 8/9-2/3

<em><u>Unknown:</u></em>

Second part of wire

<em><u>2. Make the numbers have equal denominators</u></em>

2/3 * 3/3

= 6/9

<em><u>3. Solve</u></em>

8/9 - 6/9

= 2/9

Hope this helped,
