The best estimate for the number of fish is that there are 82 yellow fish and 18 green fish, which you can calculate using the rule of three. This estimate is expected to be accurate.

This can be calculated using a rule of three as follows. Let's start with the yellow fish:

53 = 65

x    = 100

53 x 100 / 65 = 82 yellow fish

Green fish:

12 = 65

x = 100

12 x 100 / 65= 18 green fish

This estimate is expected to be accurate; however, there might be small differences in real life such as 80 yellow fish and 20 green fish.

Using the t-distribution, it is found that the 99% confidence interval for the difference is (0.058, 3.462).

We are given the standard deviation for the samples, hence, the t-distribution is used to solve this question.

The standard errors are given by:

\(s_A = \frac{1.79}{\sqrt{18}} = 0.4219\)

\(s_B = \frac{1.95}{\sqrt{18}} = 0.4596\)

For the distribution of differences, the mean and the standard error are given by:

\(\overline{x} = \mu_A - \mu_B = 23.95 - 22.19 = 1.76\)

\(s = \sqrt{0.4219^2 + 0.4596^2} = 0.6239\)

The interval is given by:

\(\overline{x} \pm ts\)

The critical value for a two-tailed 99% confidence interval with 18 + 18 - 2 = 34 df is t = 2.7284.

Then:

\(\overline{x} - ts = 1.76 - 2.7284(0.6239) = 0.058\)

\(\overline{x} + ts = 1.76 + 2.7284(0.6239) = 3.462\)

The 99% confidence interval for the difference is (0.058, 3.462).

Answer:

5x=6+12y  or 5x=12y+6

Step-by-step explanation:

The expression that matches the statement "5x is 6 more than 12y" can be written as 5x = 12y + 6.

Variables:

In this expression, "x" and "y" are variables.

Variables are symbols that can take on different values.

The specific values of "x" and "y" unless they are provided or defined in a given context.

Equality:

The equal sign "=" in the expression indicates that the expression on the left side is equal to the expression on the right side.

This means that whatever value we assign to "x" and "y," the expression's left and right sides will have the same value.

Operations:

The expression involves mathematical operations.

On the left side, we have "5x," which means "5 times x" or "5 multiplied by x."

On the right side, we have "12y + 6," which means "12 times y plus 6."

Relationship between 5x and 12y + 6:

The expression states that "5x" is equal to "12y + 6."

This means that if we take any value of "x" and plug it into "5x,"

it will be equal to the value obtained by taking any value of "y," multiplying it by 12, and then adding 6 to the result.

Therefore, 5x = 12y + 6 represents a expression between the variables x and y as per given statement.

Answer:

3 boxes of small porridge

Step-by-step explanation:

625g x 5 = 3125

4125-3125=1000

1000 divided by 350 = 2.8

so there will be 2 full boxes of small porridge and 1 not full box of porridge.

Walter buys 3 small boxes of oat porridge.

When used to represent a quantity or a mathematical relationship, symbols and/or numbers are combined to form an expression in mathematics. It may contain exponents, brackets, variables, constants, and mathematical operations like addition, subtraction, multiplication, and division.

To begin, let's determine how much porridge is contained in the five enormous boxes:

5 x 625 = 3125g

Determine how much porridge is contained in the little boxes since we know that Walter purchases 4175g in total.

4175 - 3125 = 1050g

Assuming that there are 350g of porridge in each small box, we can calculate the number of small boxes by dividing the total weight of the porridge by the weight of each small box:

1050 / 350 = 3

Therefore, Walter buys 3 small boxes of oat porridge.

The equation of the linear relationship in slope-intercept form is y = 2x - 8. Option A is the correct answer.

To determine the equation of the linear relationship in slope-intercept form based on the table, we need to find the slope and y-intercept.

By observing the table, we can calculate the slope by selecting any two points. Let's choose the points (0, -8) and (4, 0).

Slope (m) = (change in y) / (change in x)

= (0 - (-8)) / (4 - 0)

= 8 / 4

= 2

Now that we have the slope, we can find the y-intercept by substituting the values of one point and the slope into the equation y = mx + b and solving for b.

Using the point (0, -8):

-8 = 2(0) + b

b = -8

Therefore, the equation of the linear relationship in slope-intercept form is: y = 2x - 8. Option A is the correct answer.

Step-by-step explanation:

2 is the initial amount, growth rate is (3ˣ - 1) × 100% , domain of the function is all real numbers and  range of the function is all positive real numbers

A relation is a function if it has only One y-value for each x-value.

The given function is:

f(x) = 2(3)ˣ

To find the initial amount, we need to find f(0):

f(0) = 2(3)⁰ = 2(1) = 2

So the initial amount is 2.

To find the growth rate, we can use the formula:

growth rate = (f(x) - f(0)) / f(0) × 100%

= (2(3)ˣ - 2) / 2 × 100%

= (3ˣ - 1) × 100%

So the growth rate is (3ˣ - 1)×100%.

The domain of the function is all real numbers because the function is defined for all values of x.

The range of the function is all positive real numbers because the function is always positive for any value of x.

Specifically, the range of the function is (0, infinity).

Hence, 2 is the initial amount, growth rate is (3ˣ - 1) × 100% , domain of the function is all real numbers and  range of the function is all positive real numbers

The nominal rate per annum compounded half-yearly, equivalent to an effective rate of 14.5% per annum, is approximately 14.900625%.

To convert an effective rate to a nominal rate compounded half-yearly, we can use the formula:

Nominal rate \(= (1 + r/m)^m - 1\)

Where:

r = effective rate

m = number of compounding periods per year

In this case, the effective rate is 14.5% per annum, and we want to convert it to a nominal rate compounded half-yearly.

Since compounding is done semi-annually, m would be 2.

Plugging in the values:

Nominal rate \(= (1 + 0.145/2)^2 - 1\)  

Simplifying the expression inside the parentheses:

Nominal rate \(= (1 + 0.0725)^2 - 1\)

Calculating the exponent:

Nominal rate \(= (1.0725)^2-1\)

Performing the calculations:

Nominal rate = 1.14900625 - 1

Nominal rate = 0.14900625

Converting the nominal rate to a percentage:

Nominal rate = 14.900625%

Answer:

B. \( \sqrt{116} \)

Step-by-step explanation:

Lenght of segment AB is the distance between A(-3, 1) and B(7, 5):

\( AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \)

Let,

\( A(-3, 1) = (x_1, y_1) \)

\( B(7, 5) = (x_2, y_2) \)

\( AB = \sqrt{(7 - (-3))^2 + (5 - 1)^2} \)

\( AB = \sqrt{(10)^2 + (4)^2} \)

\( AB = \sqrt{100 + 16} = \)

\( AB = \sqrt{116} \)

The value of x in chords is 25.857 and this is a isosceles triangle.

In geometry, a chord is a line segment that connects two points on the circumference of a circle. A chord is the longest distance between two points on a circle, and it passes through the center of the circle. The endpoints of a chord are referred to as its "endpoints." A chord that passes through the center of a circle is called the "diameter" of the circle. The length of a chord can be calculated using the Pythagorean theorem, given the radius and the distance between the center and the chord. Chords are used in various geometric calculations involving circles, such as finding the area of a sector or segment of a circle.

The sum of the angles of a triangle is 180 degrees. In a circle, the angle subtended by an arc at the center of the circle is twice the angle subtended by the same arc at any point on the circumference. Using these facts, we can set up the following equation to find x:

(1/2)(14x - 7) + (1/2)(12x + 4) + (1/2)(4x) = 180

Simplifying and solving for x, we get:

7x - 1 = 180

7x = 181

x = 25.857

Therefore, x is approximately equal to 25.857.

where :

x = u + v ,  y = u - v ,  z = 1 + 2u + v ,  

0 ≤ u ≤ 5,  

0 ≤ v ≤ 1

R ( u,v ) = < u+v , u-v , 1 + 2u +v >   next we have to differentiate

attached below is a detailed solution

The surface integral S(x + y + z) dS, where S is the parallelogram is \(115\sqrt{14} /2\) and this can be determined by integrating the given expression.

Given :

The surface integra S(x + y + z) dS, S is the parallelogram with parametric equations  x = u + v, y = u − v, z = 1 + 2u + v, 0 ≤ u ≤ 7, 0 ≤ v ≤ 3.

The following calculation can be used in order to determine the surface integral.

\(\rm R_u\times R_v = <3,1,-2>\)

\(\rm ||R_u\times R_v|| = \sqrt{14}\)

Now, evaluate the surface integral.

\(\rm I = \rm \int\int_s(x+y+z)dr\)

\(\rm I = \int^5_{u=0}\int^1_{v=0}(u+v+u-v+1+2u+v)||R_u\times R_v||dA\)
