A marble is selected at random from a jar containing 5 red marbles, 2 yellow marbles & 3 green marbles. What is the probabil
lisabon 2012 [21]

Answer:

5/11

explanation

Probability here is the chance of selection out of a total. So, we need to first find the total number of marbles.

total

=

5

+

3

+

2

+

1

=

11

So there are  

11

marbles total. The probability that we pick one of the  

3

green marbles out of the  

11

is simply that ratio:

P

green

=

3

11

Same idea for yellow:

P

yellow

=

2

11

The probability of picking either of these colors is simply the sum of their probabilities.

P

green or yellow

=

P

green

+

P

yellow

=

Help me please ill give 5 star rating
babymother [125]

Answer:

Option A. 7\ basil and 11\ squash

Step-by-step explanation:

Let

b-----> the number of packets of basil seed

s-----> the number of packets of squash seeds

we know that

b+s=18

b=18-s -----> equation A

1.5b+2.5s=38 -----> equation B

substitute equation A in equation B and solve for s

1.5(18-s)+2.5s=38

27-1.5s+2.5s=38

s=38-27

s=11

Find the value of b

b=18-11=7

therefore

7\ basil and 11\ squash

A scale model of a street sign is in the shape of a triangle. The base is 4.25 cm and the height is 8.8 cm what is the area of t
agasfer [191]

Answer:

18.7 cm²

Step-by-step explanation:

To work out the area of a triangle you have to use the formula

\frac{1}{2} * B * H

Where "B" is the base and "H" is the height

Since these are decimals, I like to convert them into fractions which makes them easier to calculate with

The base is 4.25 cm which will turn into 4\frac{1}{4}

The height is 8.8 cm which will turn into 8\frac{8}{10}

Now we use the formula

 \frac{1}{2} * B * H

 \frac{1}{2} * 4\frac{1}{4} *8\frac{8}{10}

→ Convert to improper fractions

 \frac{1}{2} * \frac{17}{4} *\frac{88}{10}

→ Simplify

 \frac{187}{10}

→ Convert into decimal

18.7
