12x12.5=150
Steps:
1. convert 12.5 into a fraction: 25/2
2. also convert 12 into a fraction: 12/1
3. multiply 25/2x12/1=150.
Hope I helped! :D
Answer:
E. None of the above
Step-by-step explanation:
We know that 1/8 is the same as 1÷8 Then using Long Division for divided by 8 gives us 0.125
Answer:
Step-by-step explanation:
1/4 cup of sugar = 1/2 tea spoon. (1)
Multiplying both sides by 4, we have
1/4 * 4 cup of sugar = 1/2 * 4 tea spoon. (2)
1 cup of sugar = 2 tea spoon
( Required answer)
Answer:
And we can find this probability with the following difference:
And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the number of gallons of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability with the following difference:
And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.
1 yard = 36 inches
The fraction (1 yard / 36 inches) has a numerator and denominator
that are equal. So the fraction is equal to ' 1 ', and we can multiply
(26 inches) by it without changing any value. That'll change the units
of the '26 inches' to 'yards', which is exactly what we need.
(26 inches) x (1 yard/36 inches) = (26/36) yard
That's 13/18 yard, or 0.7222... yard.
