Answer:
3
Step-by-step explanation:
3 is a whole number and estimating from the tenth places the number is a 1 which means you go back to an 3 not an 4.
The term that best describes the given statement above is the third option which is negation. In geometry, a negation statement is the opposite of a given mathematical statement. If a statement is true, then its negation is false. And if a statement is false, then its negation is true. The given statement above is false, therefore, it is a negation of the true statement.
Answer:
What do u need the help for?
Step-by-step explanation:
Part a: For variable X using z score you have (x-30)/10, replace X for this expression in (a), i mean Z=2+10((x-30)/10) = 2+x-30= put this in the way of z score = (x-18)/1, so the mean is 18 and standard deviation is 1.
Part b: Z=X+Y= (x-30)/10 + (x-20)/8 = solve adding fractions = (18x-440)/80 now divide all the numbers between 18 (because you need to show as z score way) = (x-24.4)/4.4, so the mean is 24.4 and standard deviation is 4.4.
For part c,do the same.
