-- I've decided to name the unknown number ' Q ', because I can.
-- The product of 25 and the unknown number is 25 Q .
-- The quotient of that product and 45 is 25 Q/45 .
-- We're told that this quotient is -65 .
25 Q / 45 = -65 .
22 in first box.
6 in second box
22=2x+6
Subtract 6 from both sides
16= 2x
Divide both sides by 2.
X=8. Third box is 8
Answer:
h(t) = 12 inches + (1 inch/week)t; continuous
Step-by-step explanation:
This situation can be described with a linear function. The initial value of the plant height is 12 inches, and the weekly growth is 1 inch/week.
Thus, if h(t) represents the plant height at the end of the t-th week,
h(t) = 12 inches + (1 inch/week)t
The slope is 1 inch/week, and is continuous, since plan growth is continuous.
X plus the 28 degree equals 90
so x = 90-28 = 62 degrees
Answer: The critical value for a two-tailed t-test = 2.056
The critical value for a one-tailed t-test = 1.706
Step-by-step explanation:
Given : Degree of freedom : df= 26
Significance level :
Using student's t distribution table , the critical value for a two-tailed t-test will be :-
The critical value for a two-tailed t-test = 2.056
Again, Using student's t distribution table , the critical value for a one-tailed t-test will be :-
The critical value for a one-tailed t-test = 1.706
