Answer: If you mean 5% of $14.98, it is $0.75 75 cents

If you mean 14.98 represents a 5% commission on what sale amount

The sale amount was $299.60

Step-by-step explanation:

Change the percent to a decimal and multiply by the sale amount.

0.05 × 14.98 = .749 Round to .75

If 14.98 is the 5% commission, divide 14.98/.05= 299.60

Find the values of cosΘ and tanΘ, given that sinΘ = 8/9 and Θ is in quadrant I

Misha Larkins [42]

$sin^2 \alpha +cos^2 \alpha =1\ \ \ and\ \ \ tan \alpha = \frac{\big{sin \alpha }}{\big{cos \alpha }} \\\\sin \alpha = \frac{8}{9}\\\\ \Rightarrow\ \ \ (\frac{8}{9})^2+cos^2 \alpha =1\ \ \ \Rightarrow\ \ \ cos^2 \alpha =1- \frac{64}{81} \ \ \ \Rightarrow\ \ \ cos^2 \alpha = \frac{17}{81} \\\\ \alpha \ \in\ (0^0;90^0)\ \ \ \Rightarrow\ \ \ cos \alpha >0\ \ \ \Rightarrow\ \ \ cos \alpha = \frac{ \sqrt{17} }{9} \\\\$

$tan \alpha = \frac{8}{9}: \frac{ \sqrt{17} }{9} =\frac{8}{9}\cdot \frac{9}{\sqrt{17}}= \frac{8}{\sqrt{17}}= \frac{8\cdot \sqrt{17}}{\sqrt{17}\cdot \sqrt{17}}=\frac{8\cdot \sqrt{17}}{17}$

Thirteen students entered the business program at Sante Fe College 2 years ago. The following table indicates what each student

gizmo_the_mogwai [7]

Answer:

y=1.003009+0.003453x

GPA=1.003009+0.003453(SAT Score)

Step-by-step explanation:

The least square regression equation can be written as

y=a+bx

In the given scenario y is the GPA and x is SAT score because GPA depends on SAT score.

SAT score (X) GPA (Y) X² XY

421 2.93 177241 1233.53

375 2.87 140625 1076.25

585 3.03 342225 1772.55

693 3.42 480249 2370.06

608 3.66 369664 2225.28

392 2.91 153664 1140.72

418 2.12 174724 886.16

484 2.5 234256 1210

725 3.24 525625 2349

506 1.97 256036 996.82

613 2.73 375769 1673.49

706 3.88 498436 2739.28

366 1.58 133956 578.28

sumx=6892

sumy=36.84

sumx²=3862470

sumxy=20251.42

n=13

$b=\frac{(nsumxy)-(sumx)(sumy)}{nsumx^{2}-(sumx)^{2} }$

b=9367.18/2712446

b=0.003453

a=ybar-b(xbar)

ybar=sum(y)/n

ybar=2.833846

xbar=sum(x)/n

xbar=530.1538

a=2.833846-0.003453*(530.1538)

a=1.003009

Thus, required regression equation is

y=1.003009+0.003453x.

The least-squares regression equation that shows the best relationship between GPA and the SAT score is

GPA=1.003009+0.003453(SAT Score)
