A telephone solicitor is responsible for canvassing three suburbs. In the past, 60% of the completed calls to Belle Meade have r

igor_vitrenko [27]

Answer:

0.4625 or 46.25%

Step-by-step explanation:

The data for the percentage of contribution and the percentage of numbers from each suburb is presented in the table bellow:

$\begin{array}{ccc}&Contribution (C)&Number(N)\\Belle\ Mead&0.60&0.25\\Oak\ Hill&0.55&0.25\\Antioch&0.35&0.5\end{array}$

The probability that she gets a donation is given by the sum of the probabilities of getting a donation from each suburb weighed by their respective percentage of numbers of the list:

$P(C) = P(C_B)+P(C_O)+P(C_A)\\P(C) =0.6*0.25+0.55*0.25+0.35*0.5\\P(C) = 0.4625$

The probability that she gets a donation is 0.4625 or 46.25%.

Your teacher is giving a test worth 250 points. There are 68 questions. Some questions are worth 5 points and the rest are worth

NARA [144]

There are 38 five point questions and 30 two points questions.

Step-by-step explanation:

Given,

Worth of points in test = 250

Number of questions = 68

Let,

x represent the number of 5 points questions

y represent the number of 2 points question

According to given statement;

x+y=68 Eqn 1

5x+2y=250 Eqn 2

Multiplying Eqn 1 by 2

$2(x+y=68)\\2x+2y=136\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(5x+2y)-(2x+2y)=250-136\\5x+2y-2x-2y=114\\3x=114$

Dividing both sides by 3

$\frac{3x}{3}=\frac{114}{3}\\x=38$

Putting x=38 in Eqn 1

$38+y=68\\y=68-38\\y=30$

There are 38 five point questions and 30 two points questions.

What equivalent fractions do the number lines show?

maks197457 [2]

Hello there, I'm Steel42, and I am here to help you today.

Let's look at some key words:

Equivalent - somethings that is equal in amount, value, or function

Fractions - It represents a part of a whole

Now, our problem,

Q:How do you find equivalent fractions?
A: If you can multiply or divide the top and bottom numbers by the same number, there equal.

Lets see if any are equal:
1 whole equals two 1/2
1 whole equals three 1/3
1 whole equals four 1/4
1 whole equals five 1/5
1 whole equals six 1/6
1 whole equals seven 1/7
1 whole equals eight 1/8

one 1/2 equals two 1/4
one 1/2 equals three 1/6
one 1/2 equals four 1/8
two 1/2 equals one whole

one 1/3 equals two 1/6
three 1/3 equals 1 whole

one 1/4 equals two 1/8
four 1/4 equals one whole
two 1/4 equals one whole

two 1/6 equals one 1/3
six 1/6 equals one whole
three 1/6 equals one 1/2
three 1/6 equals two 1/4
three 1/6 equals four 1/8

two 1/8 equals one 1/4
four 1/8 equals one 1/2
four 1/8 equals two 1/4
four 1/8 equals three 1/6
eight 1/8 equals one whole

Hope This helps you today : )
