Answer:

1500 grams of grain

Step-by-step explanation:

How many grams of grain will there be in 2.4 kg of shelled hazelnuts?

Step 1

Convert kg to g

1 kg = 1000g

2.4 g = x

Cross Multiply

x = 2.4 × 1000g = 2400g

Step 2

An 800 gram sample of shelled hazelnuts has 500 grams of grain.

Hence,

800g hazelnuts = 500 gram of grain

2400g hazelnuts = x

Cross Multiply

800x = 2400g × 500g

x = 2400g × 500g/800

x = 1500 grams of grain

8. There are 10 balls in a bag numbered from 1 to 10. Three balls are selected at random without replacement.
PIT_PIT [208]

Answer:

a. 720

b. 0.3

Step-by-step explanation:

a.

Three balls are selected at random without replacement.

First ball can be selected in 10 ways

Second ball can be selected in 9 ways

Third ball can be selected in 8 ways

Thus, there are 10×9×8 =720 different ways of selecting three balls.

b.

There are three cases that satisfy this condition

  1. first ball picked is 5, the others are not
  2. first ball is not 5, second is 5, third is not
  3. first and second ball is not five, third ball is 5

Each probabilities are:

  1. \frac{1}{10} * \frac{9}{9} *\frac{8}{8} =\frac{1}{10}
  2. \frac{9}{10} *\frac{1}{9} *\frac{8}{8} =\frac{1}{10}
  3. \frac{9}{10} *\frac{8}{9} *\frac{1}{8} =\frac{1}{10}

Thus, one of the balls selected is the number 5 is then \frac{1}{10} + \frac{1}{10} + \frac{1}{10} = \frac{3}{10}

How do I find B in y=mx+b?
mixas84 [53]
If you already have an equation, all you have to do is locate the slope and look after it. But if it's in a graph, it's where the line is crossing the y-axis.

An example of the equation would be

y=2x+3
y=mx+b
2 would be m which is slope
and 3 would be b which is the y-intercept
