Help me please, what are the like terms?

andriy [413]

Step-by-step explanation:

Like terms are are terms whose variables (and their exponents such as the 2 in x 2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.

So like in your picture x and x would be like terms... your picture helps as well to identify your like terms because your like terms have the same background color to there particular rectangle.

There are 785 students in the senior class. If there are 77 more females in the class than males, how many male and female senio

VLD [36.1K]

There are 431 females

785-77=708
708/2=354
354=males
354+77=431
431=females
to check work do 431=354 and that equals 785

Please answer all for brainlest and thanks !!! I'm begging :((

You can find a unit rate when given a rate by dividing the the second number in the rate (if you had 3:4, you would divide 4) by the same number. (in the problem I gave you, you would divide 4 by 4 to get 1 then divide 3 by 4.) Then you would have the unit rate. Sorry if that didn't make any sense.

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)
