$0.81 per cup.

There are 4 cups in a quart, so there are 8 cups in total . $6.48 ÷ 8 = $0.81

Answer:

Step-by-step explanation:

surface area = 2πrh + 2πr²

where r = 2 miles radius

          h = 3 miles

plugin values into the formula

surface area = 2πrh + 2πr²

                     = 2π (2) 3  +  2π (2)²

                     = 37.699  +  25.133

                     = 62.832 mi.²

Step-by-step explanation:

A cheese is said to be classified as either raw-milk or pasteurized.

Given that: 82% is pasteurized,

Then:

Supposed two cheeses are chosen at random;

P(both cheeses are pasteurized) = 0.82 × 0.82

= 0.6724

If four cheeses are chosen at random;

P(that all four cheeses are pasteurized) = 0.82 × 0.82 × 0.82 × 0.82

P(that all four cheeses are pasteurized) = 0.452

The required probability for at least one of the four randomly selected  cheeses is raw milk is:

P(at least one of the randomly selected cheese is raw milk) = 1 - P(that all four cheeses are pasteurized)

P(at least one of the randomly selected cheese is raw milk) = 1 - 0.452

P(at least one of the randomly selected cheese is raw milk) = 0.548

However, since the probability that at least one of the randomly selected cheese is raw milk  is greater than one; then we can conclude that;

It is not  unusual that at least one of four randomly selected cheeses is raw-milk.

Answer:

The length of slide is 18.36 meters

Step-by-step explanation:

The given scenario forms a right-angled triangle where

The height of tower id perpendicular, the distance between slash pool and base of tower is base and the length of slide will be hypotenuse.

Height of tower = h = 16 meters

Distance between slash pool and base of tower = b = 9 meters

Length of slide = s = ?

As it is a right angled triangle, we can use Pythagoras theorem to find the length of slide

Pythagoras theorem states that:

[tex](Hypotenuse)^2 = (Base)^2+(Perpendicular)^2\\s^2 = b^2+h^2\\s^2 = (9)^2+(16)^2\\s^2 = 81+256\\s^2 = 337\\s^2 = 18.36\ meters[/tex]

Hence,

The length of slide is 18.36 meters

Answer:46

Step-by-step explanation:

The amount of outdoor carpet needed is 40 ft².

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.

Area of a rectangle = length × width.

The amount of square feet of outdoor carpet needed

= area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle)

The amount of square feet of outdoor carpet needed

= 12 × 4 - (3 × 2 + 2 × 1)

= 48 - (6 + 2)

= 40 ft²

Thus, 40 ft² outdoor carpet needed.

Answer:

Yes

Step-by-step explanation:

Well, this is a powers of powers problem. So the rule is that we always add our exponents and it will equal the same thing.

So therefore x3*x3*x3=x9=x9

Answer:

Fraction of Book Dillon Read on Monday and Tuesday is [tex]\mathbf{\frac{3}{5} }[/tex]

Step-by-step explanation:

Dillon read book on Monday = [tex]\frac{1}{5}[/tex]

Dillon read book on Tuesday = [tex]\frac{2}{5}[/tex]

We need to find fraction of the book did he read on Monday and Tuesday

So, Fraction of Book Dillon Read on Monday and Tuesday= Book read on Monday + Book read on Tuesday

Fraction of Book Dillon Read on Monday and Tuesday= [tex]\frac{1}{5}+\frac{2}{5}[/tex]

[tex]=\frac{1+2}{5} \ (Taking \ LCM \ of \ 5 \ and \ 5 \ we \ get \ 5) \\=\frac{3}{5}[/tex]

So, Fraction of Book Dillon Read on Monday and Tuesday is [tex]\mathbf{\frac{3}{5} }[/tex]

[tex]a_n=11-10\,n[/tex]

Step-by-step explanation:

Notice that in the sequence :

1, -9, -19, ...  one term differs from the following by a constant number that is subtracted from the first one. There is what is called a "common difference" (d = -10)

the first term is "1", and we can apply the formula for the nth term of an arithmetic sequence for which we know the first term , and the common difference:

[tex]a_n=a_1+(n-1) * d\\a_n=1\,+\,(n-1)*(-10)\\a_n=1-10\,n+\,10\\a_n=11-10\,n[/tex]

Answer:6mm

Step-by-step explanation:

So we know that you started with 100% and ended with 600% to get from 100 to 600 you would need to multiply by 6

100 * 6 = 600

So you know that to get back to your original number you would need to divide by 6

If you are trying to figure out what the original width is you would divide your current number by 6 to get the original number

36 / 6 = 6

Answer c. -4

Step-by-step explanation:

Equations

Given:

f(x) = 2x + 7

We need to find the value of x such that:

f(x) = -1

Equating:

2x + 7 = -1

Subtracting 7:

2x = -1 - 7

Operating:

2x = -8

Dividing by 2:

x = -8 / 2 = -4

x = -4

Answer c. -4

Answer:

Count them?

Step-by-step explanation:

Note: Consider we need to find each type of coins he has.

Given:

Erin has quarters and nickels for a total of 16 coins.

The value of his coins is $2.60.

To find:

The number of each type of coins.

Solution:

Let x represent the number of quarters and y represent the number of nickels.

According to the question,

Total coins : [tex]x+y=16[/tex]        ...(i)​

Total value : [tex]0.25x+0.05y=2.60[/tex]        ...(ii)​

Multiply equation (i) by 0.25 and subtract the result from (ii).

[tex]0.25x+0.05y-0.25(x+y)=2.60-0.25(16)[/tex]

[tex]0.25x+0.05y-0.25x-0.25y=2.60-4[/tex]

[tex]-0.20y=-1.40[/tex]

Divide both sides by -0.20.

[tex]y=7[/tex]

Put y=7 in (i).

[tex]x+7=16[/tex]

[tex]x=16-7[/tex]

[tex]x=9[/tex]

Therefore, the number of quarters is 9 and number of nickels is 7.

Explanation:

Erase the line from angle C to angle A. You'll be left with only one transversal. This transversal forms angles B and D, which are alternate interior angles. They are inside the parallel lines, so that's what makes them interior. They are also on alternating sides of the transversal line. Alternate interior angles are congruent when we have parallel lines like this.

Side note: Another pair of alternate interior angles would be angle A and angle E.

Answer:

The slope of this line is 0.2

Answer:

x = 3 in

Step-by-step explanation:

Since it's a square, to find the area, all you have to do is multiply one side of the square by another. Since this is a square, all the sides are equal. so 3x3 = 9. 9 sq. in.

Answer:

1)0.4, 2) 0.004, 3) 0.04, 4) 4

Answer:

0.0549

0.7617

0.2383

Step-by-step explanation:

Given that:

Probability that incoming email is spam ;

P(spam) = 0.38

If three emails are in my inbox, what is the probability that:

A. All three messages are spam.

P(1st message being spam) * p(second message being spam) * p(3rd message being spam)

= (0.38) * (0.38) * (0.38)

= 0.054872

= 0.0549

B. At least one of the three messages are spam.

1 - p(none of the 3 messages are spam)

P(none of the 3 messages are spam)

P(not spam) = 1 - p(spam) = 1 - 0.38 = 0.62

1 - [P(not spam) * p(not spam) * p(not spam)]

1 - (0.62 * 0.62 * 0.62)

= 1 - 0.238328

= 0.761672

= 0.7617

C. None of the three messages are spam.

P(not spam) = 1 - p(spam) = 1 - 0.38 = 0.62

P(not spam) * p(not spam) * p(not spam)

(0.62 * 0.62 * 0.62)

= 0.238328

= 0.2383

Answer:

[tex]\frac{427}{100}[/tex]

Step-by-step explanation:

4.27 * 100 = 427

[tex]\frac{427}{100}[/tex]

Answer:

427/100

Explanation:

As a proper fraction it would be 4 and 27/100, so to make it improper you multiply 4 times 100 and add that to 27.

Answer:

B. multiply both sides by c.

Step-by-step explanation:

To solve the equation for x, you have to isolate the x variable on one side of the equation. To do this, do the opposite of any operation applied to x to remove other variables from the x's side of the equation:

x/c = d

multiply both sides of the equation by c to isolate x:

(x/c) * c = d * c

x = dc

Now x can be solved for.

Hope this helps :)

Answer: 60.93 < μ < 69.07

Step-by-step explanation: The true mean of a set of data is between an interval of values with a percentage of precision, e.g., a 99% confidence interval means we are 99% confident the true mean is between the lower and upper limits.

To find the interval, use

x±[tex]z\frac{s}{\sqrt{n}}[/tex]

z is z-score related to the % of confidence level

In this case, a 99% confidence interval is 2.576

x is sample mean

Calculating:

[tex]x=\frac{63+69+62+66}{4}[/tex]

x = 65

65±[tex]2.576\frac{3.16}{\sqrt{4}}[/tex]

65±4.07

Confidence Interval: 60.93 < μ < 69.07

Meaning that we are 99% sure the population means is between 60.93 and 69.07.
