The new yearly income is $86920.
Convert 6% into a decimal which is 0.06.
1ST METHOD:
82000*0.06=4290
4290+82000=86920
2ND METHOD:
0.06+1=1.06
82000*1.06=86920
The answer is: [C]: " 3.200 * 10⁷ h " .
_________________________________________________
Explanation:
________________________________
19.2 * 10⁸ min * (1 hr / 60 min) ;
= (19.2 * 10⁸)
_______________ ;
60
_____________________________
Divide EACH SIDE of the fraction by "10" ; to get:
___________
(19.2 * 10⁷)
_______________ ;
6
<span>______________________________
</span>⇒ (19.2) ÷ (6) = 3.2 ; so rewrite as:
_________________________________________________________
3.2 * 10⁷ ; which corresponds with:
Answer choice: [C]: " 3.200 * 10⁷ h " .

y=2
Step-by-step explanation:
Make an equation of straight line by using the formula :y= mx+c
put the x-value of point (2,4) which is 2 and the gradient,m which is 2 into the straight line equation:
y=2x +c
So you need to find the y-intercept to complete the equation, therefore:
when y=0,
0=2(2)+c
c=-4
next the question ask to find the y-coordinate when x =3, therefore you just need to replace x in the equation with 3:
y=2(3)-4
y=4
Answer:
Step-by-step explanation:
The Hypothesis :
H0 : σ = 10
H1 : σ ≠ 10
The Chisquare statistic, χ² ;
χ² = [(n-1) * s²] ÷ σ²
Sample size, n = 44 ; sample Standard deviation, s = 10.7 ; population standard deviation, σ = 10
χ² = [(44 - 1) * 10.7²] ÷ 10²
χ² = [43 * 114.49] ÷ 100
χ² = [4923.07] ÷ 100
χ² = 49.2307
Using the Pvalue from Chisquare calculator :
degree of freedom, df = n - 1 = 44 - 1 = 43
Pvalue = 0.238
