In mathematics, a square is the result of multiplying a number by itself. The verb "to square" is used to denote this operation. Squaring is the same as raising to the power 2, and is denoted by a superscript 2; for instance, the square of 3 may be written as 32, which is the number 9.
Miguel: 500 out of 750 students have part time jobs.
500 ÷ 250 = 2
750 ÷ 250 = 3
500:750 = 2:3
A) 200 out of 300 ⇒ 200/100 and 300/100 ⇒ 2:3
B) 700 out of 1100 ⇒ 700/100 and 1100/100 ⇒ 7:11
C) 800 out of 1200 ⇒ 800/400 and 1200/400 ⇒ 2:3
D) 9000 out of 1300 ⇒ 9000/100 and 1300/100 ⇒ 90:13
Among the choices, Choice B could represent Kureshi's Data because it is not proportional to the data of Miguel.
Choice D is not possible. You cannot have a result that is way beyond the scope of your population. It is impossible to get 9000 students out of only 1300 students.
Answer:
the price per pound she paid for the ground turkey = $10.515
the price per pound for the white fish
= $5.915
Step-by-step explanation:
Let x = cost of one pound of ground turkey.
Let y = cost of one pound of white
fish
Mrs.Willy bought 3 1/2 (7/2) pounds of ground turkey and 2 1/2(5/2) pounds of white fish and she paid a total of $51.59. This means
7x/2 + 5y/2= 51.59 - - - - - - -1
the white fish is $4.60 per pound cheaper than the ground turkey. This means
y = x - 4.60
To find the price per pound she paid for the ground turkey and the price per pound for the white fish,
substitute y= x - 4.60 in equation 1
7x/2 + 5y/2= 51.59
3.5x +2.5y = 51.59
3.5x + 2.5(x-4.6) = 51.59
3.5x + 2.5x - 11.5= 51.59
6x = 51.59+11.5= 63.09
x = 63.09/6 = $10.515
Substituting x = 10.515 in equation y = x - 4.60,
y = 10.515-4.60
= $5.915
Answer:
Yes, (x - 3) is a factor of P(x) and 3 is a zero or root of P(x)
Step-by-step explanation:
Determine whether or not (x - 3) is a factor by using synthetic division with +3 as the divisor. The coefficients of the polynomial p(x) are {2 -5 -4 0 9}.
Setting up synthetic division:
3 / 2 -5 -4 0 9
6 3 -3 -9
-------------------------------
2 1 -1 -3 0
Since the remainder is zero (0), we know that 3 is a root of the polynomial P(x) and that (x - 3) is a factor of said polynomial.
