Generally, the equation for the function is mathematically given as

f(x) = -5x + 11 + 10

Therefore

When x >= -1, the function decreases because f(x) = -5(x+1)+10.

This means that the function is dropping throughout this range\((-1,\infty).\)

Answer:

To calculate the mean length of the insects found, we can use the following formula:

Mean length = (Sum of lengths) / (Number of lengths)

We can calculate the sum of lengths by adding up the lengths of all the insects and dividing by the number of insects:

Sum of lengths = Length (0) + Length (10) + Length (20)

Sum of lengths = 0 mm + 10 mm + 20 mm

Sum of lengths = 30 mm

Number of lengths = 3

Mean length = Sum of lengths / Number of lengths

Mean length = 30 mm / 3

Mean length = 10 mm

Therefore, the mean length of the insects found is 10 mm.

Answer:

a = 27

Step-by-step explanation:

3/4 = a/36                  Cross multiply

4*a = 36*3                  Combine the right

4a = 108                     Divide by 4

4a/4 = 108/4

a = 27

The area of the circle here is 616cm².

The space a circle takes up in a two-dimensional plane is known as the area of the circle.

Alternately, the area of the circle is the area included inside the circumference or perimeter of the circle.

A = πr², where r is the circle's radius, is the formula for calculating a circle's surface area.

Diameter of circle = 28cm.

So here area of the circle =

π (28/2)²

= 22×14×14/7

= 616 cm²

Therefore, area of the circle here is 616cm².

A circle is a geometric shape that is defined as a closed curve in which all points are equidistant from a single point called the center.

Circles have several properties, including circumference (the distance around the circle), diameter (the distance across the circle passing through the center), and radius (the distance from the center to any point on the circle).

The cost spent on fill the box with sand is 405$.

According to the statement

we have given a square sandbox with length 9 ft and depth of 1 ft.

and the rupees of sand per cubic ft is $5

then

Now, we have to find the volume of sandbox with the given length and depth.

So, for this purpose we use Volume formula

V = (a)^3

V = 9*9*1

V = 81 cubic feet

And the cost of sand per cubic feet is $5.

then

The cost of sand for 81 cubic per feet is calculate by multiplication formula then

Total cost of sand = 81*5

Total cost of sand = 405$

So, The cost spent on fill the box with sand is 405$.

Answer: Small box: $13; Large box: $16

Explanation:

Make two individual equations for Perry and Alberto. Perry's equation would be 7x+12y=283. Alberto's equation would be 8x+6y=200. The best way to find the variables is to change the equations into slope-intercept form. Perry's equation would change to y=-7/12x+283/12 and Albert's equation would change to y=-4/3x+100/3. You can try substituting and plugging -4/3x+100/3 into the other equation, so they equal each other. But, you can also just graph the equation into a graphing calculator or Desmos. When graphing it, the point of intersection should be (13,16), so the cost of a small box tangerines is $13 and a large box of tangerines is $16.

The point estimate of the population standard deviation is 5.91 (Option A)

Standard deviation refers to the spread of a data distribution and measures the distance between each data point and the mean. The sample standard deviation (s) is a point estimate of the population standard deviation σ.

The mean of the population ẋ = sum of all values/ total number of values = 97/6 ≈ 16

The point estimate of the population standard deviation S =√(∑(xi - ẋ)^2/n-1)

∑(xi - µ)^2 = (9 – 16)^2 + (13– 16)^2 + (15– 16)^2 + (15– 16)^2 + (21– 16)^2 + (24– 16)^2 = 79 + 9 + 1 + 1 + 25 + 64 = 179

Answer:

\( Area = 112.1 m^2 \)

Step-by-step Explanation:

Given:

∆WXY

m < X = 130°

WY = x = 31 mm

m < Y = 26°

Required:

Area of ∆WXY

Solution:

Find the length of XY using Law of Sines

\( \frac{w}{sin(W)} = \frac{x}{sin(X)} \)

X = 130°

x = WY = 31 mm

W = 180 - (130 + 26) = 24°

w = XY = ?

\( \frac{w}{sin(24)} = \frac{31}{sin(130)} \)

Multiply both sides by sin(24) to solve for x

\( \frac{w}{sin(24)}*sin(24) = \frac{31}{sin(130)}*sin(24) \)

\( w = \frac{31*sin(24)}{sin(130)} \)

\( w = 16.5 mm \) (approximated)

\( XY = w = 16.5 mm \)

Find the area of ∆WXY

\( area = \frac{1}{2}*w*x*sin(Y) \)

\( = \frac{1}{2}*16.5*31*sin(26) \)

\( = \frac{16.5*31*sin(26)}{2} \)

\( Area = 112.1 m^2 \) (to nearest tenth).

The surface described by the equation \(r^2 + z^2 = 4\)is a right circular cylinder with a radius of 2 units, centered along the z-axis.

The surface whose equation is given is a cylinder with a radius of 2 units and a height of 4 units, centered on the z-axis.
Hi! I'd be happy to help you identify the surface with the given equation. The equation provided is:

\(r^2 + z^2 = 4\)

This equation represents a right circular cylinder with a radius of 2 units, centered along the z-axis. Here's why:

1. Notice that the equation contains r^2 and \(z^2\) terms, which suggests a cylindrical coordinate system.
2. The equation does not contain the θ term, which implies that the surface is symmetric about the z-axis.
3. The equation is in the form \(r^2 + z^2\) = constant, which is the equation of a right circular cylinder in cylindrical coordinates.

Step-by-step explanation:

The annual profit in 2004 was $32,000.Let's assume that the annual profit in 2004 was $x. Then, we can set up an equation based on the information given in the problem:

If the annual profit is $14,000 or lower: Albert's share = 0.3x

If the annual profit is higher than $14,000: Albert's share = $6,000 + (x - $14,000)/5

Since Albert's and Mr Toh's shares of the annual profit in 2004 were equal, we can set these two expressions equal to each other and solve for x:

0.3x = $6,000 + (x - $14,000)/5

Multiplying both sides by 5:

1.5x = $30,000 + x - $14,000

Simplifying:

0.5x = $16,000

x = $32,000

Therefore, the annual profit in 2004 was $32,000.

For a normal beach, the wave heights are best described by the median and IQR. The median and IQR are the appropriate choices.

The median and IQR are the appropriate responses.

The reason for this is that the mean will not be a true representation of the data if one of the individual numbers in the data set is an outlier (much larger or smaller than the rest, as the waves during a stormy day). Due to that one figure, the mean in this situation will be greater than the expected average.

The MAD will have comparable outcomes to the mean.

The IQR and median serve as measures of the centre portion of the data, which is more akin to the median and IQR of the wave heights.
