Find the value (s) for each of the f cases. Round your answers to 3 decimal places. Enter negative values as a Upper tal area of 025 with 12 degrees of freedom is a. Upper tail area of 0.25 with 12 degrees of freedom is .
b. Lower tail area of .005 with 55 degrees of freedom is
c. Upper tail area of .20 with 30 degrees of freedom is
d. where 98% of the area falls between these two t-values with 20 degrees of freedom.

answer: 12

step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
