who is the current vice president of the us? is this a statistical question or a non statistical question why or why not? Explai
Llana [10]

Answer:

The current vice president (as of 4-16-2021) of the U.S. is Kamala Harris. This is a non-statistical question.

Step-by-step explanation:

A statistical question can be answered by collecting data and where there will be variability in that data. The proposed question (Who is the current vice president of the U.S.?) does not allow for variability in the data as there is only one legitimate answer to the question, thus it is NOT a statistical question.

Algebra help? 2 questions will give brainliest!!
galina1969 [7]
1) x + 3.2= -3.5
subtract 3.2 from both sides
x+ 3.2 - 3.2= -3.5 - 3.2
it cancels out on the left
x= -6.7


2) 8/9x= 32
divide both sides by 8/9
8/9x ÷ 8/9= 32 ÷ 8/9
it cancels out on the left

to divide on the right, multiply fraction by its reciprocal/inverse

x= 32 * 9/8
multiply numerators (top)

x= (32*9)/8
x= 288/8
x= 36


ANSWER: 1) x= -6.7; 2) x= 36

Hope this helps! :)
