What adds to 17 but multiplies to 45

I am Lyosha [343]

No whole numbers do as if you look at the factors pairs of 45 none of them add to 17:

1, 45 = 46
3, 15 = 18
5, 9 = 14

The two numbers that add to 17 but multiply to 45 are can be calculated using the quadratic formula and are actually 13.72 and 3.28

The average age of all students at a certain college is 22 years and the standard deviation is 2 years. What is the probability

Marianna [84]

Answer:

The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159

Step-by-step explanation:

According to the given data we have the following:

mean = μ= 22

standard deviation = σ = 2

n = 100

μx = 22

σx=σ/√n=2/√100=0.2

Therefore, P( x < 21.8)=P(x-μx)/σx<(21.8-22)/0.2

=P(z<-1)

= 0.159

The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159

Answer:

Equation: $36=4s$

Solution: $s=9$

Step-by-step explanation:

A square is a quadrilateral that has four equal sides and four equal angles that measure 90 degrees (An angle that measures 90 degrees is also known as "Right triangle".

By definition, the perimeter of a square can be calculated by multiplying the length of any of its sides by 4 (because all its sides are congruent, as it was explained before).

In this case, you know that the perimeter of this square is 36 feet.

Then, you can write the following equation to model this situation:

$36=4s$

Where "s" is the length of any side of the square.

Then, you need to solve for "s" in order to find its value. Divide both sides of the equation by 4.

You get that it is:

$\frac{36}{4}=\frac{4s}{4}\\\\s=9$

1. Change each of the following equations to the form

Evgen [1.6K]

Answer:

(a) -6x- y = 3

$6x + y = -3\\ y = -6x -3$

(b) 3x-4y =12

$3x - 4y = 12\\-4y = -3x +12\\4y = 3x -12\\\\y = \frac{3}{4}x -3$

(c)-2x + 5y = 10

$-2x + 5y = 10\\5y = 2x + 10\\y = \frac{2}{5}x + 2$

(d) x + 2y = 4

$x+2y=4\\2y = -x + 4\\y = \frac{-1}{2} x +2$

(e) 8x- 4y = 3

$8x - 4y =3\\-4y = -8x + 3\\4y = 8x -3\\y = 2x -\frac{3}{4}$

(f) 4x + 5y = -6

$4x + 5y = -6\\5y = -4x - 6\\y = \frac{-4}{5} x -\frac{6}{5}$

A recipe for chicken enchiladas is meant for six people and requires 4 1/2 pounds of chicken. If you want to serve 15 people, ho

Lelu [443]

okay so first you do 6 times 2 you got 12 so maybe 2.5 times 6 and that is 15 so now you multiply 4.5 times 2.5 and i got 11.25. So 11.25 pounds of chicken is needed.
