We can write the probability of this event happening like this:
(number of prime numbers)/(total number of sections)For recap, a prime number is a number that's greater than 1 whose only factors are 1 and itself. Take the number 7 for example; its factors are only 7 and 1.
Given this information above, let's find the prime numbers in the spinner.
1: not prime (not greater than 1)2: prime3: prime4: not prime (divisible by 2)5: primeAs you can see, we have 3/5 numbers that are prime, making the probability of landing on a prime number 3/5.
carolyn and emily are searching online for tickets to a concert. two weeks ago, the cost was $20. now the cost is $29. carolyn said the percent increase is 45% and emily said the percent of increase is about 31%. who is correct?
Answer:
Carolyn
Step-by-step explanation:
Carolyn:
45% = 0.45
We multiply the orignal price with 0.45 to see how much it increased.
[tex]20(0.45) = 9[/tex]
We then add it to the original price
[tex]20+9 =29[/tex]
Emily:
31% = 0.31
We multiply the orignal price with 0.31 to see how much it increased.
[tex]20(0.31) = 6.2[/tex]
We then add it to the original price
[tex]20+6.2=26.2[/tex]
That means that Carolyn is correct.
Which function can be used to model the graphed geometric sequence? f(x 1) = five-sixthsf(x) f(x 1) = six-fifthsf(x) f(x 1) = five-sixths superscript f (x) f(x 1) = six-fifths superscript f (x)
The function that can be used to model the graphed geometric sequence is y = 1555.2(5/6)^x
Exponential functionsThe standard exponential function is expressed as y = ab^x
Using the coordinates (3, 900) and (4, 750)
Create the equations
900 = ab^3 ............. 1
750 = ab^4 ................. 2
Divide
900/750 = 1/b
b = 75/90
b = 5/6
Determine the value of "a"
900 = a(5/6)^3
900 = (125/216)a
a = 1555.2
Determine the required equation
y = 1555.2(5/6)^x
Hence the function that can be used to model the graphed geometric sequence is y = 1555.2(5/6)^x

y−4=−3(x+1)
Number graph ranging from negative four to four on the x and y axes. A line is drawn on the graph that passes through (negative one, four) and (one, negative two).
Answer: Choice D
y-4 = -3(x+1)
========================================================
Explanation:
Let's first find the slope of the line through (-1,4) and (1,-2)
[tex](x_1,y_1) = (-1,4) \text{ and } (x_2,y_2) = (1,-2)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{-2 - 4}{1 - (-1)}\\\\m = \frac{-2 - 4}{1 + 1}\\\\m = \frac{-6}{2}\\\\m = -3\\\\[/tex]
The slope is -3, which tells us that the answer must be choice D.
Choices A,B, & C can be eliminated because choices A and B have a slope of -13, while choice C has a slope of 3.
Refer to the point-slope format [tex]y-y_1 = m(x - x_1)[/tex] where m is the slope and [tex](x_1,y_1)[/tex] is a point the line goes through.

Does Anybody know this? Find the area of the shaded sector
Step-by-step explanation:
your teacher was very nice and warned you about the trap in the question.
so, really, what do we have to do ?
a full circle represents 360°.
the shaded sector is the full circle minus the white sector !
this is the same as directly calculating the shaded sector for 360-75 = 285°.
so, the area of a circle is
pi×r²
in our case
pi×20² = 400pi
the needed fraction of the whole circle is either
75/360, if we want to subtract it for the solution
or
285/360, if we want to calculate the solution directly.
both lead to the same result.
400pi×360/360 - 400pi×75/360 =
= 400pi × 285/360 = 10pi × 285/9 = 2850pi/9 =
= 316.6666666...pi ≈ 316.7pi

Step-by-step explanation:
there are 13 out of 52 diamond cards.
and there are 26 out of 52 black cards.
so, for the first card to be diamond the probability is
13/52 = 1/4 = 0.25
but now, he does not put the card back.
he pulls the second card out of 51 possible cards.
the desired cases are still 26.
so, the probability to pull a black card as the second card under the restriction that the first card was a diamond is
26/51 = 0.509803922...
the probability for that combined event is then
1/4 × 26/51 = 26/204 = 13/102 = 0.12745098...
so, c. is the right answer.

how do you measure the perimeter of a shape
Perimeter is a measure of the area or distance around a two-dimensional shape. On a rectangle, for instance, the perimeter is the total length of the rectangle's outline, including the two widthwise borders and the two lengthwise borders.
To determine the perimeter of a shape, therefore, you add together all the dimensions that make up the shape's outer edge. Being able to find the perimeter of a shape has many applications in the real world. Say, for example, that you wanted to build a fence around your backyard. In order to purchase materials, you need to know how much fencing you'll need, and to determine that you have to figure out the perimeter of the area you want to fence in.

both points have the same x value.
that means they are both on the same vertical line at x = 6.
so, we only need to calculate the y difference, and that is then their distance :
1 - -3 = 1 + 3 = 4

(3x-5y)+(x+2y)? Someone help me. Will give brainliest
Answer: 4x - 3y (choice B)
===========================================================
Explanation:
The letter x is a variable, and a placeholder for a number. Which number? We don't know. It's basically a box where a number goes inside.
x represents having 1 box
2x is two boxes, and so on
If we add 3x and 1x, then we'll have four boxes and 3x+1x = 4x
We can only add the x terms together, which we consider to be called "like terms".
The y terms -5y and 2y are the other pair of like terms, which combine to -3y
If you want, you can draw a vertical number line. Start at -5 which is five units below zero. Then move up two spaces to arrive at -3. This is a visual way to demonstrate that -5+2 = -3, and by extension, -5y+2y = -3y
Type the correct answer in each box. use numerals instead of words. consider the quadratic equation x2 10x 27 = 0. completing the square leads to the equivalent equation (x )2 = .
The equivalent equation using the completing the square method is (x+5)² = -2
Completing the square method.Quadratic equations are equation that has a degree of 2. Given the equations expressed as:
x^2+10x+27 = 0
Subtract 27 from both sides
x^2+10x = -27
Complete the squares
x^2+10x = -27
x^2+10x + 5^2= -27 + 25
(x+5)² = -2
Hence the equivalent equation using the completing the square method is (x+5)² = -2

What is a square?It is a polygon with four sides. The total interior angle is 360 degrees. A square's opposite sides are parallel and all sides are equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
There are two squares.
The perimeter of square x is half the perimeter of square y.
Let the side of the square x be a and the side length of the square y be b. Then we have
Perimeter x = Perimeter y / 2
4a = 2b
2a = b
Then the area of the square x will be
Area of square x = (2a)²
Area of square x = 4a²
Then the area of the square y will be
Area of square x = (b)²
Area of square x = b²
Then the area of square x will be one-fourth of the area of square y.
Thus, the correct option is C.

Using the monthly payment formula, it is found that the amount he will have to pay is given as follows:
a. $151.73.
What is the monthly payment formula?It is given by:
[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]

P = 2513.77, r = 0.1066, n = 1.5 x 12 = 18.
Hence:
r/12 = 0.1066/12 = 0.008883.
[tex]A = 2513.77\frac{0.008883(1 + 0.008883)^{18}}{(1 + 0.008883)^{18} - 1} = 151.73[/tex]
