A garden table and a bench cost $840 combined. The garden table costs $60 less than the bench. What is the cost of the bench?

The algebraic expression for the cost of entering a state park and camping for n nights, with an entry fee of $6.00 and a nightly fee of $7.50, is Cost = $6.00 + ($7.50 times n).

The algebraic expression to represent the cost in dollars of entering a state park and camping for n nights, when the state park charges a $6.00 entry fee plus $7.50 per night of camping, is calculated as follows:

Cost = Entry fee + (Cost per night times Number of nights)

Here, the entry fee is $6.00, and the cost per night is $7.50. Therefore, the expression becomes:

Cost = $6.00 + ($7.50 times n)

Where n represents the number of nights spent camping.

The number 4 shows up 14 times

The number 3 shows up 6 times

This is a total of 14+6 = 20 times we get a 3 or a 4 on the dice

This is out of 64 total rolls

Use a calculator to find that 20/64 = 0.3125

Move the decimal point over 2 spots to the right to get 31.25%

Lastly, round this to the nearest whole number percent to get 31%

Keep in mind that this only works for experimental probability. Theoretical probability is going to be different.

Answer:

√85 or 9.22

Step-by-step explanation:

For this, you'd want to use the distance formula, which is just something you'd eventually memorize.

Distance = [tex]\sqrt{(x_{2}- x_{1})^{2} + (y_{2}- y_{1})^{2}}[/tex]

Then, you'd plug in the values. Something to keep in mind is the coordinate that is farther right will be ([tex]x_{2} ,y_{2}[/tex]), since [tex](x_{2}- x_{1})[/tex] is supposed to represent the change in x (and same with the y).

d = √( (7 - (-2))² + (9 - 7)²)

= √( (9²) + 2²)

= √(81 + 4)

= √85

= 9.22

I hope this helps!

The distance between point (7, 9) and point (-2, 7) is √85 units.

To find the distance between two points, you can use the distance formula:

[tex]\[d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\][/tex]

In this case, the coordinates of the two points are:

Point 1: (7, 9)

Point 2: (-2, 7)

Now, plug these coordinates into the distance formula:

[tex]\[d = \sqrt{(-2 - 7)^2 + (7 - 9)^2}\][/tex]

Simplify inside the square root:

[tex]\[d = \sqrt{(-9)^2 + (-2)^2}\][/tex]

[tex]\[d = \sqrt{81 + 4}\][/tex]

[tex]\[d = \sqrt{85}\][/tex]

So, the distance between point (7, 9) and point (-2, 7) is[tex]\(\sqrt{85}\)[/tex] units, which is an irrational number and cannot be simplified further as a whole number or fraction.

Answer: 49929 years ago

Step-by-step explanation:

Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms

To calculate the time, we will use exponential formula

R% = e^ -kt

Where t = number of years

0.25/100 = e^- 0.00012t

Log both sides with natural logarithm

Ln0.0025 = lne^-0.00012t

-5.9915 = -0.00012t

t = 5.9915/0.00012

t = 49928.9 years

Approximately t = 49929 years

The whale died approximately 49,929 years ago.

To determine how long ago the whale died, we use the fact that its vertebrae contain roughly 0.25% as much carbon-14 as they originally did when the whale was alive. This suggests the carbon-14 has decayed, following its known decay rate.

The carbon-14 decay formula is:

N(t) = N0 × [tex]e^{-kt}[/tex]

where:

Given that N(t)/N0 = 0.0025, we solve for t:

1. Divide both sides by N0:

0.0025 = [tex]e^{(-0.00012 * t)}[/tex]

2. Take the natural logarithm of both sides:

ln(0.0025) = -0.00012 × t

3. Solve for t:

t = ln(0.0025) / -0.00012

t = −5.991464547/−0.00012

Calculating this, we get:

t ≈ 49928.87 ≈ 49,929 years

Therefore, the whale died approximately 49,929 years ago.

We are 99% confident interval for the population proportion of passing test scores between ( 0.5987  and 0.9413 )

Step-by-step explanation:

Given -

n = 40

Population proportion = [tex]\widehat{(p)}[/tex] = [tex]77\%[/tex] = .77

1 - [tex]\widehat{(p)}[/tex] = 1 - .77 =.23

[tex]\alpha[/tex] = 1 - confidence interval = 1 - .99 = .01

[tex]z_{\frac{\alpha}{2}}[/tex] = [tex]z_{\frac{.01}{2}}[/tex] = 2.58

99% confidence interval for the population proportion of passing test scores=

[tex]\widehat{(p)}\pm z_{\frac{\alpha}{2}} \sqrt{\frac{\widehat{(p)} (1 - \widehat{p})}{n}}[/tex]

= [tex].77\pm z_{\frac{.01}{2}} \sqrt{\frac{{(.77)} (.23)}{40}}[/tex]

= [tex].77\pm 0.1713[/tex]

= [tex](.77 + 0.1713 , .77 - 0.1713)[/tex]

= ( 0.5987 , 0.9413 )

Answer:

You mean that if we have two pairs of points, (x1, y1) and (x2, y2)

we can find the slope of the line that conects those two points as:

a = (y2 - y1)/(x2 - x1)

remember that a linear equation has the shape:

y(x) = a*x + b

Now let's prove it:

for our case we have that

y1 = a*x1 + b

y2 = a*x2 + b

we can isolate be in both equtaions and get:

b = y1 - a*x1

b = y2 - a*x2

this means that:

y1 - a*x1 = y2 - a*x2

then:

a*x2 - a*x1 = y2 - y1

a*(x2 - x1) = y2 - y1

a = (y2 - y1)/(x2 - x1)

Which is the thing we wanted to get.

The subtraction of y-values and x-values to find the slope of a line is based on measuring the rate of change of y (rise) per unit change in x (run). This concept is fundamental in determining and understanding the steepness of a line on a graph.

To understand why we subtract y-values and x-values to find the slope, let's look at the formula for the slope of a line, m = (y2 - y1) / (x2 - x1). Here, 'm' represents the slope of the line, the y values (y2 and y1) represent points on the vertical axis, and the x values (x2 and x1) represent points on the horizontal axis.

When we say 'slope', we mean how steep a line is. That steepness is determined by how much y changes (the rise) for a certain amount of change in x (the run). By subtracting y-values and x-values from each other, we are able to accurately measure this change, and therefore calculate the slope of the line.

Graphically, if we consider two points on a straight line, the slope of the line (m) can be seen as how much the line rises (the difference in y-values) for each unit it runs horizontally (the difference in x-values).

Answer:

A : The height of the prism is is 10 cm

B : DFG is  a base

D : The appropriate unit of measure for the volume is cubic centimetres

Step-by-step explanation:

In the given right triangular prism, ADFG constitutes one of the bases, and the appropriate unit for volume is cubic centimeters. However, details about the height and the specific area of the base are not conclusively determined. (2 and 4 are correct)

Let's analyze each statement:

1. The height of the prism is 10 cm.

  - This statement is not necessarily true. The height of a right triangular prism is typically measured perpendicular to the base. The provided information about AC and AD doesn't directly determine the height.

2. ADFG is a base.

  - This statement is true. A base of the right triangular prism can be identified by the vertices, and ADFG forms one of the bases.

3. ADFG is a lateral side.

  - This statement is not true. ADFG is a base, not a lateral side.

4. The appropriate unit of measure for the volume is cubic centimeters.

  - This statement is true. Volume is measured in cubic units, and in this context, cubic centimeters is appropriate.

5. The area of the base is 45 square centimeters.

  - This statement is not necessarily true. The area of the base cannot be determined solely from the information given.

So, the true statements are 2 and 4.

To simplify with exponents, don't feel like you have to work only with, or straight from, the rules for exponents. It is often simpler to work directly from the definition and meaning of exponents. For instance:

Simplify a6 × a5

The rules tell me to add the exponents. But I when I started algebra, I had trouble keeping the rules straight, so I just thought about what exponents mean. The " a6 " means "six copies of a multiplied together", and the " a5 " means "five copies of a multiplied together". So if I multiply those two expressions together, I will get eleven copies of a multiplied together. That is:

Simplify –(46x2y3z)0

The parenthetical portion still simplifies to 1, but this time the "minus" is out in front of the parentheses; that is, it's out from under the power, so the exponent doesn't touch it. So the answer in this case is:

Therefore,

[tex]k^0 = 1[/tex] (anything raised to the power of 0 is 1).

[tex]k^-3 = 1/k^3[/tex] (negative exponent indicates reciprocal).

Therefore,

Step-by-step explanation:

Answer:

x² + y² = 144

Step-by-step explanation:

The general equation of a circle is given as

(x - a)² + (y-b)² = r²

where a and b are the center of the circle along the x and y axis respectively and r is the radius of the circle.

Hence a circle that has its center at the origin and has a diameter of 24 units, we can deduce that the values of a,b are 0,0. Also,

radius = diameter/2

= 24/2

= 12 units

Hence the standard equation of the circle

(x - 0)² + (y - 0)² = 12²

x² + y² = 144

Answer: The mistake caused the perimeter to increase by 4 inches

The mistake caused the area to increase by 13 square inches

Step-by-step explanation: The original dimensions have been given as 5 inches by 7 inches. If this measurement had been correctly used, the perimeter was supposed to be;

Perimeter = 2(L + W)

Perimeter = 2(5 + 7)

Perimeter = 2(12)

Perimeter = 24 inches

Also the area was supposed to be;

Area = L x W

Area = 5 x 7

Area = 35 square inches

However, Sam accidentally printed a photo that is 6 inches by 8 inches, therefore the effect would be as follows;

Perimeter = 2(L + W)

Perimeter = 2(6 + 8)

Perimeter = 2(14)

Perimeter = 28 inches

And the Area would be

Area = L x W

Area = 6 x 8

Area = 48 square inches

From the calculations so far, the mistake would cause the perimeter to increase by 4 inches (28 inches - 24 inches).

Also the area would likewise increase by 13 inches (48 inches - 35 inches).
