The required container can hold (10/3) times the amount of water poured into it.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Let's assume the container can hold "x" gallons of water.

According to the problem, the container is 1/5 full initially, which means it contains (1/5)x gallons of water.

After pouring in some water, it is 7/10 full, which means it contains (7/10)x gallons of water.

The difference between the initial and final amounts of water is the amount of water poured into the container. Therefore, we can set up an equation:

(7/10)x - (1/5)x = the amount of water poured into the container

(7/10 - 1/5)x = (3/10)x = the amount of water poured into the container

We know that this amount of water is in gallons, so we have:

(3/10)x = the amount of water poured into the container in gallons

We can solve for "x" by dividing both sides by 3/10:

x = (the amount of water poured into the container in gallons) / (3/10)

x = (10/3) x (the amount of water poured into the container in gallons)

Therefore, the container can hold (10/3) times the amount of water poured into it.

On a coordinate plane, a vector has origin (0, 0) and terminal point (3, 2). The magnitude of the vector is 5

The magnitude of a vector can be calculated using the distance formula, which is the square root of the sum of the squares of the differences of the x and y components. In this case, the x component is 3 and the y component is 2, so the magnitude can be calculated as follows:

The value of side TS is,

⇒ TS = 28

First, we are going to divide the figure and named new points X and Y as:

Now, we know that TS is the sum of TX and XS.

TS = TX + XS

Additionally, TX has the same length of HJ, so:

TX = HJ = 14

Now, we want to know the length of YK, and we can calculate it using the following equation:

LK = LY + YK

LY = HJ,

so, LY = 14

And, 42 = 14 + YK

42 - 14 = YK

28 = YK

Finally, since T and S are midpoints, the length of XS is the half of the length of YK. It means that XS is:

XS = YK/2

XS = 28/2

XS = 14

Therefore, TS is equal to:

TS = TX + XS

TS = 14 + 14

TS = 28

Answer:

okay, so we have a wall that is 60 ft. The area of the wall because the wall is a square is just side squared. So the area of the wall is \(60^{2}\), which is 30 600 square feet. The mirror is 20 ft by 60 ft. So the area of the mirror, because its a rectangle is length times width, so that's 20 a 60 so 20 x 60 is gonna give me 1200 square feet. So if we take the area of the mirror and put that over the area, the wall we get 1200 over 30 600, which reduces to one over three. So the mirror is one third the area of the wall.

The estimates for the average content is 0.9.

The variation in nitrogen content in the colony is 0.0036.

The average of a data set or the mean of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

The sum of the data set is calculated as follows;

total = 0.98 + 0.83 + 0.99 + 0.86 + 0.9 + 0.81 + 0.94 + 0.92 + 0.87

total = 8.1

The estimated average of the nitrogen content  = 8.1/9 = 0.9

The deviation of each data from the mean;

= (0.98 - 0.9), (0.83 - 0.9), (0.99 - 0.9), (0.86 - 0.9), (0.9 - 0.9), (0.81 - 0.9), (0.94 - 0.9), (0.92 - 0.9), (0.87 - 0.9)

= 0.08, -0.07, 0.09, -0.04, 0, -0.09, 0.04, 0.02, -0.03

The sum of the square of each data from the mean;

= (0.08)² + (-0.07)²  + (0.09)² + (-0.04)² + (0.0)² + (-0.09)² + (0.04)² + (0.02)² + (-0.03)²

= 0.032

Hence, either x < -7 or x > -7 is the right response.

Many students find algebra intimidating since it's the first math course they take where they have to deal with variables, abstract ideas, and problem-solving skills. Also, there is sometimes insufficient effort made in the class to relate algebra to students' daily lives and convey why learning it is important.

As divide by zero is undefinable, the function f(x) remains defined for any and all real integers other than the one that sets the denominator to zero. As a result, we must determine what value of x results in the fraction, x + 7, being equal to zero:

x + 7 = 0

x = -7

Hence, for x = -7, the function is under. All real integers fall within the scope of the function, with the exception of x = -7, which is able to be represented by the interval notation:

(-∞, -7) U (-7, ∞)

Hence, the appropriate response is x < -7 or x > -7.

The number of hours Julian was at the resort is given by the equation

A = 6 hours

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of hours Julian was at the resort be A

Now , the equation will be

The total amount spend by Julian = $ 121

The cost for renting a snowboard = $ 55

The cost per hour for lift ticket = $ 11

So , for x hours of lift ticket = 11x

Substituting the values in the equation , we get

The total amount spend by Julian = cost for renting a snowboard  + x hours of lift ticket

On simplifying the equation , we get

121 = 55 + 11x

Subtracting 55 on both sides of the equation , we get

11x = 66

Divide by 11 on both sides of the equation , we get

Step-by-step explanation:

7 divided by 9 is .7777777777....

Answer:

Part A:

To find the percentage of survey respondents who liked neither hamburgers nor burritos, we need to calculate the frequency in the "Does not like hamburgers" and "Does not like burritos" categories.

Frequency of "Does not like hamburgers" = Total in "Does not like hamburgers" category = 135

Frequency of "Does not like burritos" = Total in "Does not like burritos" category = 54

Total respondents who liked neither hamburgers nor burritos = Frequency of "Does not like hamburgers" + Frequency of "Does not like burritos" = 135 + 54 = 189

Percentage of survey respondents who liked neither hamburgers nor burritos = (Total respondents who liked neither hamburgers nor burritos / Total respondents) x 100

Percentage = (189 / 205) x 100 = 92.2%

Therefore, 92.2% of the survey respondents liked neither hamburgers nor burritos.

Part B:

To find the marginal relative frequency of all customers who like hamburgers, we need to divide the frequency of "Likes hamburgers" by the total number of respondents.

Frequency of "Likes hamburgers" = 110 (given)

Total respondents = 205 (given)

Marginal relative frequency = Frequency of "Likes hamburgers" / Total respondents

Marginal relative frequency = 110 / 205 ≈ 0.5366 or 53.66%

Therefore, the marginal relative frequency of all customers who like hamburgers is approximately 53.66%.

Part C:

To determine if there is an association between liking burritos and liking hamburgers, we can compare the joint and marginal frequencies.

Joint frequency of "Likes hamburgers" and "Likes burritos" = 29 (given)

Marginal frequency of "Likes hamburgers" = 110 (given)

Marginal frequency of "Likes burritos" = 70 (calculated by adding the frequency of "Likes burritos" in the table)

To assess the association, we compare the ratio of the joint frequency to the product of the marginal frequencies:

Ratio = Joint frequency / (Marginal frequency of "Likes hamburgers" x Marginal frequency of "Likes burritos")

Ratio = 29 / (110 x 70)

Ratio ≈ 0.037 (rounded to three decimal places)
