Teachers at Price Middle School are planning a birthday party for the principal. Planners estimated that 42 slices of cake would be needed. In fact, only 30 slices of cake were eaten. What was the percent error in the estimate of how much cake was eaten? A student solved the problem and showed his work below. What was his error?

StartFraction StartAbsoluteValue 42 minus 30 EndAbsoluteValue over 42 EndFraction(100) Almost-equals 6%
The planners did not use the absolute error in the ratio.
The planners compared the absolute error to the approximate value.
The planners did not multiply by 100 to get the percent.
The planners divided incorrectly and got the wrong answer.

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

the answer is 13

the correct answer is a) "catholic church".

the proposals that liberals in mexico made during 1855 were particularly focused on a person's individual rights, such as the freedom of speech, the freedom of conscience, freedom of assembly, and the right to possess weapons.

when the constitution was formally published 2 years later (1857). it also contained an article which permitted education free from any religious influence, the removal of the catholic church institutional privileges, and the sale of property belonging to the church. all of these provisions were clearly against the catholic church interests.
