Answer:

0.024 represents the amount of snow that is added to the lawn every minute.

Step-by-step explanation:

Emily observed the amount of snow on her lawn during a blizzard. So, 0.024 in the equation shows the rate at which snow is coming with the number of minutes passing.

Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

For an unknown quantity represented by an unknown variable, equations are then solved to determine its value. It is clear that a statement is not even an equation if there is no "equal to" sign in it.

As per the given equation in the question,

S is the snow in inches.

x shows the time in minutes and,

0.024 is the rate along with the time at which the snow is accumulating in the lawn and 7 in the equation is the constant value.

log_7(2)+log_7(3)

log_7(2×3)

log_7(6)

Answer:

yes

Step-by-step explanation:

see attached graph - there are two real roots for y=2x^4-6x^2+10x-7

so 2x^4-6x^2+10x-7 can be expressed as:

(x - root1)(x - root2)(2x^2+Bx+C)

Answer:

Yes, it can be.

Step-by-step explanation:

Using solver program, the expression 2x^4-6x^2+10x-7 has:

two real roots at x≈-2.3888 and x≈1.1424

and

two complex roots at x≈0.62321 - 0.94559 i and x≈0.62321 + 0.94559 i

Because it has two real roots, the expression can be simplified.

Answer:

x = 5√2

y = 15

Step-by-step explanation:

By applying sine rule in the given right triangle,

sin(60°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{\sqrt{3} }{2}=\frac{y}{10\sqrt{2}}[/tex]

y = [tex]\frac{\sqrt{3} \times 10\sqrt{2} }{2}[/tex]

y = 15

Similarly, by applying cosine rule in the given triangle,

cos(60°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{1}{2}=\frac{x}{10\sqrt{2}}[/tex]

x = 5√2

Step-by-step explanation:

The mean for brand A is higher than the mean for brand B

The mean for brand A is higher than the mean for brand B because the mean for A is 1983.33 and the mean for B is 1600 statement (C) is correct.

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

We have:

For brand A:

The number of hours per lightbulb:

1000, 4200, 1400, 1500, 1800, 2000

Mean for brand A:

[tex]\rm Mean(A) = \frac{Sum \ of \ all \ data \ values}{Number \ of \ data \ in \ the\ set}[/tex]

[tex]\rm Mean(A)= \frac{1000+4200+1400+1500+1800+ 2000}{6}[/tex]

[tex]\rm Mean(A)= \frac{11900}{6}\\\\\rm Mean(A) = 1983.33[/tex]

For Brand B:

The number of hours per lightbulb:

1200, 1400, 1600, 1800, 2000

Mean for brand B:

[tex]\rm Mean(B) = \frac{Sum \ of \ all \ data \ values}{Number \ of \ data \ in \ the\ set}[/tex]

[tex]\rm Mean(B)= \frac{1200 +1400 +1600 +1800 +2000}{6}[/tex]

[tex]\rm Mean(B)= \frac{8000}{5}\\\\\rm Mean(B) = 1600[/tex]

We can see that:

Mean(A) > Mean(B)

Thus, the mean for brand A is higher than the mean for brand B because the mean for A is 1983.33 and the mean for B is 1600 statement (C) is correct.

Answer:

It would be the second table

Step-by-step explanation:

If you look at the three points on the graph, (2,3) (4,6) (6,9), the should correspond or match with the x and y values in the table.

In the second table, the x values are 2, 4, and 6. the y values are 3, 6, and 9.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The tank can not keep 30 tropical fish in it.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Since there needs to be an average of 2 gallons of water for each fish and there are a total of 30 tropical fish. Therefore, the amount of water needed for a total of 30 fish to flourish is,

Amount of water needed = 30 fish × 2 gallons = 60 gallons

Since One gallon is equal to 19.2152 cups. Therefore, the amount of water needed for the fish to flourish is,

60 gallons = 60 × 19.2152 cups = 1152.912 cups

Since the tank has a capacity of 976 cups only, the tank is not big enough to keep 30 fish.

Hence, the tank can not keep 30 tropical fish in it.

Step-by-step explanation:

It can't be the length, because it states in the question that the length is 7 m

and it can't be the area because lw = 7(8) = 56 is the area.

Answer:

#1 - a mathematical relationship or rule expressed in symbols which help you solve something

#2 - variables, which represent an aspect of the problem

#3 P is perimeter, L is length, W is width, A is area

#4 Because in order to find the perimeter, you need to multiply the length and the width twice then add them.

Answer:

The minimum sample size required for the estimate is of 3820.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

Variance is known to be 5.76

This means that [tex]\sigma = \sqrt{5.76} = 2.4[/tex]

What is the minimum sample size required for the estimate?

Maximum error of 0.1 means that we find n for which M = 0.1. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]0.1 = 2.575\frac{2.4}{\sqrt{n}}[/tex]

[tex]0.1\sqrt{n} = 2.575*2.4[/tex]

Multiplying both sides by 10

[tex]\sqrt{n} = 2.575*24[/tex]

[tex](\sqrt{n})^2 = (2.575*24)^2[/tex]

[tex]n = 3819.2[/tex]

Rounding up:

The minimum sample size required for the estimate is of 3820.
