What is the equation that represents the line?

Answer:

31.416

Step-by-step explanation:

2 times Pi (3.14) times the radius (5)

The radius into the formula gives a circumference of 10π feet.

The circumference of a circle can be calculated using the formula:

Circumference = 2 x π x radius

Given that the radius of the circle is 5 feet, we can substitute this value into the formula to find the circumference:

Circumference = 2 x π x 5 = 10π feet

Therefore, the circumference of the circle is 10π feet.

Answer:

P(X >= 86) =  P (Z  >= 1) = 0.1587 from the Z-scores table

Step-by-step explanation:

Hopefully this time I will not make an algebraic mistake.

Ok

so  mean u = 79,  and standard dev = s = 7

We want P(X >= 86)

Standardize:

P ( (X - u)/s  >=  (86 - 79)/7 ) =  P (Z  >= 1) = 0.1587 from the Z-scores table

if it is P(x<=86) the answer is 0.84

Answer:

[tex]\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right][/tex]

Step-by-step explanation:

When making a matrix of two equations with the variables x and y, the result will be a matrix with three columns:

since our system of equations is:

[tex]3x-5y=12\\ 4x-2y=15[/tex]

we can see that the value for x in the first equation is 3 and in the second equation is 4, thus the first column will have the numbers 3 and 4:

[tex]\left[\begin{array}{ccc}3&&\\4&&\\\end{array}\right][/tex]

Now for the values of y we hvae -5 in the first equation and -2 in the second equation, we update the matrix with another column with the values of -5 and -2:

[tex]\left[\begin{array}{ccc}3&-5&\\4&-2&\\\end{array}\right][/tex]

Finally, the last column is the independent values of each equation (or the results) in the first equation that number is 12 and in the second equation is 15, thus the matrix is:

[tex]\left[\begin{array}{ccc}3&-5&12\\4&-2&15\\\end{array}\right][/tex]

usually there is a line separating the columns for the values of x and y, and the independent values:

[tex]\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right][/tex]

this is the matrix of the system of equations

Answer + Step-by-step explanation:

Jackson spent $8.85 on watermelon and p*3 dollars on cherries, which simplifies to 8.85 + 3p dollars.

Tim spent $3.35 on pineapple and p*2 dollars on cherries, which simplifies to 3.35 + 2p dollars.

To find how much more Jackson spent than Tim, we can subtract Tim's total cost from Jackson's total cost, giving:

(8.85 + 3p) - (3.35 + 2p) = 5.50 + p

So Jackson spent $5.50 + p more than Tim.

Final answer:

To find the diameter of the base of the cylinder, use the formula for the volume to solve for the radius, then double the radius to find the diameter.

Explanation:

To find the diameter of the base of the cylinder, we need to first find the radius. We can use the formula for the volume of a cylinder, V = πr²h, where V is the volume, r is the radius, and h is the height. Rearranging the formula to solve for the radius, we have r = √(V/πh).

Plugging in the given values: V = 63.6 cubic inches and h = 9 inches, we can find the radius: r = √(63.6/3.142 x 9).

Calculating the values: r ≈ √(20.2649) ≈ 4.5055 inches. The diameter is twice the radius, so the diameter ≈ 2 x 4.5055 ≈ 9.011 inches.

Answer:

[tex]x = - 4 \: or \: x = - 14[/tex]

Step-by-step explanation:

We have been given the equation

[tex](x + 9) {}^{2} = 25[/tex]

and we are asked to apply the square root property of equality to our given a equation and isolate the variable

First, take the square root of both sides of our equation

[tex] \sqrt{(x + 9) {}^{2} } = \sqrt{25} [/tex]

[tex]x + 9 = \: 15[/tex]

[tex]x + 9 = 5 \: or \: x + 9 = - 5[/tex]

[tex]x + 9 - 9 = 5 - 9 \: or \: x + 9 - 9 = - 5 - 9[/tex]

[tex]x = - 4 \: or \: x = - 14[/tex]

THEREFORE, THERE ARE TWO SOLUTIONS FOR OUR GIVEN EQUATION

[tex]x + 9 = 5 \: then \: x = - 4. \\ x + 9 = - 5 \: then \: x = - 14[/tex]

The probability that none of the chosen cards were spades is 27/64.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

A student draws three cards from a standard deck of cards. If the student replaces the card after each draw.

Number of spades card = 13

The number of non-spade cards would be 39

The probability that none of the chosen cards were spades = Number of favorable outcomes / total number of outcomes

=  27/64.

Thus, The probability that none of the chosen cards were spades is 27/64.

Answer:

1.2

Step-by-step explanation:

Write out the equation and let mbe the missing number:

8 × m = 9.6

Divide 8 to both sides:

[tex]\frac{8}{8}[/tex] × m = [tex]\frac{9.6}{8}[/tex]

Simplify for M

m = 1.2

The number that needs to be multiplied by 8 to yield the product of 9.6 is 1.2. This is calculated by dividing 9.6 by 8.

The student is asking to solve for a number that when multiplied by 8 results in the product of 9.6. This can be solved by a straightforward division operation. When we say, 'a number multiplied by 8 equals 9.6', we're actually writing an equation for multiplication. To get that number, we'll need to divide 9.6 by 8 because division is the inverse operation of multiplication.

Here's how you do it, step-by-step:

The solution to 9.6 ÷ 8 is 1.2. So, the number multiplied by 8 to get 9.6 is 1.2.

Answer:

area = 6[tex]\sqrt{14}[/tex]  units²

Step-by-step explanation:

Given the 3 sides of a triangle, we can use Hero's formula to calculate the area (A)

A = [tex]\sqrt{s(s-a)(s-b(s-c)}[/tex]

where s s the semi perimeter and a, b , c the sides of the triangle

let a = 5, b = 9 and c = 10

s = [tex]\frac{a+b+c}{2}[/tex] = [tex]\frac{5+9+10}{2}[/tex] = [tex]\frac{24}{2}[/tex] = 12

A = [tex]\sqrt{12(12-5)(12-9)(12-10)}[/tex]

   = [tex]\sqrt{12(7)(3)(2)}[/tex]

   = [tex]\sqrt{504}[/tex]

   = [tex]\sqrt{36(14)}[/tex]

   =  6[tex]\sqrt{14}[/tex] units²

Answer:

Step-by-step explanation:

a = 5 units ; b = 9units ; c = 10 units

Semi perimeter = (a+b+c)/2 = (5+9+10)/2 = 24/2 = 12 units

s-a = 12 -5 = 7 units

s -b = 12 - 9 = 3 units

s-c = 12- 10 =2 units

[tex]Area=\sqrt{s*(s-a)(s-b)(s-c)}\\\\=\sqrt{12*7*3*2}\\\\=\sqrt{2*2*3*7*3*2}\\\\=2*3\sqrt{2*7}\\\\=6\sqrt{14}\\[/tex]

Answer:

1) 1.4%

2) 8.3%

3) 20.8%

Step-by-step explanation:

Alrighty! You are looking at some compound probability problems.

The trick with these is to figure out the probability of each piece of an event, and then multiply those together to get the overall probability.

Quick note about notation: p(event A) is short hand for saying "The probability of event A is....."

1) Flipping head, rolling a 5, and rolling a 2

P(flipping heads) = 1/2

p(rolling a 5) = 1/6

p(rolling a 2) = 1/6

so: (1/2) x (1/6) x (1/6) = 1/72 or about 1.4%

2) Flipping tails, rolling an odd number, and rolling a 4

p(flipping tails) = 1/2

p(rolling an odd number) = 3/6

p(rolling a 4) = 1/6

so: (1/2) x (3/6) x (1/6) = 3/72 or about 8.3%

3) Flipping head, not rolling a 2, and rolling an even number

p(flipping heads) = 1/2

p(not rolling a 2) = 5/6

p(rolling and even number) = 3/6

so: (1/2) x (5/6) x (3/6) = 15/72 or about 20.8%

Answer:

dD

Step-by-step explanation:

The required probability is 0.687% or 0.6867.

Given Probability:
The probability that a single student exercises regularly is 37%, or 0.37.

Probability for Independent Events:
Since the events are independent events (each student's response does not influence another's), multiply the individual probabilities together. For 5 students, the calculation is :

[tex]Probability\ that\ 5\ randomly\ selected\ students\ will\ say\ thay\ they\ exercise\ regularly = P(5) = 0.37^5[/tex]

Calculation:
[tex]P(5) = 0.37^5 \approx 0.006867[/tex]

Converting to Percent:
To convert this decimal to a percentage, multiplying by 100:
[tex]0.006867 \times 100 \approx 0.6867 \%[/tex]

Rounding:
Finally, rounding to the nearest thousandth:
Probability = 0.687%

So, the probability that 5 randomly selected students will say they exercise regularly is approximately 0.687%.

Answer:

The Answer is : D

Step-by-step explanation:

First find the slope of the line that the equation should be parallel to. In this case it is 2/1 which simplified is 2.

Next insert the X (4) of the point (4,1) and solve to see if you get the Y(1).

y-1 = 2 (4-4)

y-1= 2 (0)

y-1= 0

y= 1

In this case D is correct.

TIP*

If you see the question ask you about a parallel formula, look at the slopes of them to see if they match up. Parallel formulas have the same slope, just a tip because you can see in the answer choices none of the equations have the same slope as the line on the graph except for D.
