add 38 on both sides, solve for -44 + 38 which is -6.

Answer:
Step-by-step explanation:
Use a calculator with built-in statistical functions. The function applying here is normcdf(, the "cumulative density function."
(a) The percentage of values lying between 138 and 162 is
norm(138,162, 150, 12), which comes out to 0.683, or 68.3%.
(b) Find norm(126, 174, 150,12): 0.945, or 94.5%
(c) Find norm(126,162, 150,12); 0.819, or 81.9%
(d) Find norm(162, 174,150,12): 0.136, or 13.6%
Answer:
Step-by-step explanation:
Ciao, come stai?
1) Per prima cosa, dobbiamo trovare la misura della base più grande. Scomponendo la figura possiamo visualizzare un triangolo e un quadrato. Ci sono somiglianze con gli angoli. Quindi è un triangolo rettangolo. Applichiamo il teorema di Pitagora:
2) Perimetro:
3) L' area
I guess B. That statement is grammatically incorrect.
Y=10x, 10 is the amount of money Miranda earns per hour , x is the amount of hours she works, y is the total amount of money she earns.
For Tommy’s earnings, use slope formula, which is y=y2-y1/x2-x1, take two random points from the table, (4,32) and (5,40)
(4,32) is (x1,y1). (5,40) is (x2,y2)
40-32/5-4= 8/1
The answer is 8. y=8x
Miranda earns more money per hour than Tommy.
