In order to make 4.5 gallons of orange juice, she will need 12 cartons of concentrated orange juice.

So,

The orange juice concentrate to water ratio is 12:36.

Now, let's call 'x' the amount of concentrated orange juice in 4.5 gallons of orange juice and 'y' the amount of water in the 4.5 gallons of orange juice we have;

We can conclude the following from equations (1) and (2):

x = 1.125 gallons of concentrated orange juice in 4.5 gallons of orange juice:

y = 3.375, the amount of water in 4.5 gallons of orange juice.

As a result, we have;

The number of fluid ounces in a carton is 12 ounces.

In 4.5 gallons of orange juice, x = 1.125 gallons = 144 fluidounces = 12 cartons of concentrated orange juice

Therefore, in order to make 4.5 gallons of orange juice, she will need 12 cartons of concentrated orange juice.

If at sunset a thermometer had a reading of 4°F and during the night the temperature decreased by 15°F, then after the decrease the total number of degrees that the temperature must change for the thermometer to read 0°F is equal to 11°F.

The total number of degrees that the temperature must change for the thermometer to read 0°F can be determined by using subtraction.

Subtraction can be defined as an act of calculating the difference between numbers or values.

As the temperature decreased by 15°F during the night, the temperature after the decrease can be calculated as follows,

4°F - 15°F = -11°F

The total number of degrees the temperature must change for the thermometer to read 0°F can be calculated as follows,

-11°F + x = 0

x = 11°F

Hence, the temperature must increase by 11°F for the thermometer to read 0°F.

-1.96312.. is a real, irrational number while √(-5) is imaginary. There is no value for a root of a negative number

Step-by-step explanation:

You should understand that numbers are naturally classified as real and imaginary. Under the real numbers, they are additionally classified into rational and irrational numbers. Under rational numbers, these possess fractions and integers. Irrational numbers are in decimal forms that cannot be converted to fractions. Thus, the difference between the two is that: -1.96312.. is a real, irrational number while √(-5) is imaginary. There is no value for a root of a negative number.

El área del terreno es igual a 406 metros cuadrados.

El perímetro del terreno es igual a 104 metros.

En esta pregunta tenemos conocimiento de las ecuaciones asociadas a las longitudes de la base y la altura del terreno, cuya forma es rectangular. Inicialmente, determinamos el área del terreno:

A = b · h

A = (20 - 2 · x) · (16 + 10 · x)

A = (20 - 2 · 3) · (16 + 10 · 3)

A = (20 - 6) · (16 + 13)

A = 14 · 29

A = 406 m²

El área del terreno es igual a 406 metros cuadrados.

Ahora, determinamos el perímetro del terreno:

p = 2 · (b + h)

p = 2 · [(20 - 2 · x) + (16 + 10 · x)]

p = 2 · (8 · x + 36)

p = 16 · x + 72

p = 16 · 2 + 72

p = 32 + 72

p = 104 m

El perímetro del terreno es igual a 104 metros.

Using scientific notation, it is found that:

A number in scientific notation is given by:

[tex]a \times 10^b[/tex]

With the base being [tex]a \in [1, 10)[/tex].

For this problem, the number is given by:

982.1 m².

In scientific notation, the base has to be a number between 1 and 10(open interval at 10), hence the base has to be divided by 100.

To compensate for the division by 100, the number has to be multiplied by 100 somewhere, which happens when we add 2 to the exponent, as 10² = 100.

Hence:

The number is written as follows: [tex]9.821 \times 10^2[/tex] m².

The significant digits are all the digits that are not zero, and the zeros at the beginning or between other numbers, hence they are:

9, 8, 2 and 1.

Meaning that the number has 4 significant digits.

Step-by-step explanation:

a. f(-3d) = (-3d)^2 - 2(-3d) - 8 = 9d^2 + 6d - 8

b. f(3) = (3)^2 - 2(3) - 8 = 9 - 8 - 8 = 1 - 8 = -7

c. f(2a - 1) = (2a - 1)^2 - 2(2a - 1) - 8 = 4a^2 - 4a + 1 -4a + 2 - 8 = 4a^2 - 8a - 5

d. g(5)= (2(5)+3)/(5^2 -2(5) + 1) = (10 + 3)/(25 - 10 + 1)= 13/15+1= 13/16

e. g(3x)= (2(3x) + 3))/((3x)^2 - 2(3x) + 1))= (6x + 3)/(9x^2 - 6x + 1)

f. g(-4a + 8) = (2(-4a + 8)) +  3/(-4a + 8)^2 - 2(-4a +8) +1))

Probability that the mother in this sample had a premature baby given that the mother admitted to smoking is 50 percent.

Likelihood is the part of science concerning mathematical depictions of how likely an occasion is to happen, or how likely it is that a suggestion is valid. The likelihood of an occasion is a number somewhere in the range of 0 and 1, where, generally talking, 0 demonstrates difficulty of the occasion and 1 shows conviction.

P (A) is the probability of an event “A”

n (A) is the number of favorable outcomes

n (S) is the total number of events in the sample space

The higher the likelihood of an occasion, the more probable it is that the occasion will happen. A straightforward model is the throwing of a fair coin. Since the coin is fair, the two results are both similarly likely; the likelihood of "heads" approaches the likelihood of "tails"; and since no different results are conceivable, the likelihood of by the same token "heads" or "tails" is 1/2.
