8 because 12x8=96 and 12 inches in a foot
4(2x-3) distribute the 4 to expand the expression
8x-12
Answer:
And we can find this probability with this difference:
And in order to find these probabilities using the normal standard distribution or excel and we got.
So we expect about 99.735% of values between $29 and $89
Step-by-step explanation:
Let X the random variable that represent the amount of Jens monthly phone of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability first in order to find a %
The z score is given by:
If we apply this formula to our probability we got this:
And we can find this probability with this difference:
And in order to find these probabilities using the normal standard distribution or excel and we got.
So we expect about 99.735% of values between $29 and $89
Answer:
The upper bound is 97.5 cm
Step-by-step explanation:
The upper bound is given as the value that is larger than or equal to all values in a data set, for example, in the data set, {3, 6, 16, 23, 25}, an upper bound is 25, however, where the accuracy of the data is given, the upper bound can be found by the following relation
Where the number is given to the nearest 100, add and subtract half of hundred to obtain the upper bound and lower bound respectively
For the question, given that the size of the television is given as 95 cm, correct to the nearest 5 cm, we add add half of 5 cm to get the upper bound as follows;
Upper bound = 95 cm + 5/2 cm = 97.5 cm
The upper bound = 97.5 cm.
