2 ¾= 11/4 Fraction. greater than 1 is 5/4.So, two 5/4 fits in 11/4. So, answer is 2.
Look at it this way:
When you flip a coin, the probability of it landing with EITHER side showing
is 100%.
This leads us to the rule ...
The sum of the probabilities of
all possible outcomes is 100%.
For a coin: (probability of heads) plus (probability of tails) = 100%.
That just says: We're 100% sure that the coin will land with either
heads or tails up.
An "honest" coin gets heads 50% of the time and tails the other 50%.
But if the coin is all bent and squashed and has a feather stuck to
one side and a wad of gum on the other side so that it comes up
heads 70% of the time, then the coin isn't 'honest'. But it still has to
land EITHER heads OR tails, so the sum of the probabilities is still 100%.
So the probability of heads is 30%.
Using substitution:In the first equation, look to solve for x
{x + 3 y = 8
{4 x - y = 6
Subtract 3 y from both sides:
{x = 8 - 3 y
{4 x - y = 6
Substitute x = 8 - 3 y into the second equation:
{x = 8 - 3 y
{4 (8 - 3 y) - y = 6
4 (8 - 3 y) - y = (32 - 12 y) - y = 32 - 13 y:
{x = 8 - 3 y
{32 - 13 y = 6
In the second equation, look to solve for y:
{x = 8 - 3 y
{32 - 13 y = 6
Subtract 32 from both sides:
{x = 8 - 3 y
{-13 y = -26
Divide both sides by -13:
{x = 8 - 3 y
{y = 2
Substitute y = 2 into the first equation:
Answer: {x = 2
{y = 2
Answer:
see explanation
Step-by-step explanation:
(a)
The median is represented by the solid vertical line inside the box, that is
median = 58
(b)
The interquartile range is the difference between the upper and lower quartiles.
The upper quartile is the value on the right side of the box, that is 72
The lower quartile is the value on the left side of the box, that is 34
Interquartile range = 72 - 34 = 38
(c)
The range is the difference between the maximum and minimum values
The maximum is indicated by the vertical bar on the right outside the box
The minimum is indicated by the vertical bar on the left outside the box
Range = 86 - 10 = 76
