You pick a card at random, put it back, and then pick another card at random. What is the probability of picking a 3 and then picking a number less than 3? (Write answer as a percentage)

Answer:

12:44, or if simplified 3:11

Step-by-step explanation:

In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3). Similarly, the ratio of lemons to oranges is 6∶8 (or 3∶4) and the ratio of oranges to the total amount of fruit is 8∶14 (or 4∶7).

Cone: You need the radius and height of the cone.

Cylinder: You need the radius and height the cylinder.

Sphere: You only need the radius of the sphere.

Step-by-step explanation:

For a lot of object shapes height and radius play a large role, the sphere is an outlier because of it's for a lack of a better word, spherical shape.

Answer:

Step-by-step explanation:

slope = m

m = y2-y1  /  x2 - x1

m = (-4) - 7  / (-6) - (-4)

m = -11 /  (-6) + 4

m = -11 / -2

m = 11/2

Answer:

cube

Step-by-step explanation:

The shape in the middle of the two rectangular prism would be a cube. This is the case since the angle at the base of the rectanglular prism forms a 90-degree angle. This indicates that the line is a straight line and would also form a 90-degree angle with the bottom angles as well. This would ultimately indicate that it forms a square, and since the shape is a 3-Dimensional shape it would be classified as a cube in this image.

Answer:

Triangular Prism

Answer: (4,5)

Because I don't know another way I can solve

Step-by-step explanation:

Answer:

x-intercept: (15, 0)

y-intercept: (0, 12)

Step-by-step explanation:

1.) convert the equation to y=mx+b format

4x + 5y= 60

5y = -4x + 60

y = -4/5x + 12

2.) Now we know that "b" in the equation is the y-intercept. 12 is b so the y-intercept is 12.

3.) To find x intercept we will plug in y=0.

0 = -4/5x + 12

-12 = -4/5x

15 = x

Answer:

x=2

y=5

Step-by-step explanation:

y= x+3...(1)

y= -x+7...(2)

(1) + (2):

y+y= (x+3) + (-x+7)

2y= (x-x) + (3+7)

2y= 10

y= 5

By substituting y=5 into (1),

we have

5= x+3

x+3=5

x= 5-3

x= 2

Answer:

1/3, 0.10

Step-by-step explanation:

Rational numbers can be expressed as a fraction of two integers.

1/3 is rational. When it is expressed as a fraction, it's 1/3. 1 is an integer, and 3 is an integer

0.10 is rational. It can be rewritten to be expressed as the fraction 1/10; 1 is an integer, and 10 is an integer.

.[tex]\pi[/tex] is irrational, because when expressed as a fraction, it is 1/[tex]\pi[/tex]. 1 is an integer, but [tex]\pi[/tex] is not. Both numbers need to be integers in order to be rational. Therefore, it is irrational

√2 is irrational. When expressed as a fraction, it's √2/1. √2 is not an integer. 1 is an integer. However, both numbers have to be integers in order to be rational. Therefore, √2 is not rational.

Answer:

4x^2 -3 + 1/x

Where ;

p(x) =( 4x^2 -3) and k = 1

Step-by-step explanation:

Here, we want to divide the given polynomial

To get this, we can use the method of long division

P(x) will be the quotient of the division, while k will be the remainder of the division

We can see the long division used in as seen in the attachment

So, we have the result as;

4x^2 -3 + 1/x

Where ;

p(x) = 4x^2 -3 and k = 1

Question:

The scatterplot shows the numbers of shots attempted and the corresponding number of baskets made by one of the players on the team for each of the games this season.

Apply the sketch to draw a trend line for the scatter plot (below)

Use your equation to predict the number of shots made by the player if 15 shots were attempted in the next game?

Answer #1:

The trend line for the scatterplot is (look at the image)

Answer #2:

If 15 shots were attempted in the next game, the number of shots actually made by the player would be 5. The player made 5 total shots out of the 15.

Answer:

answer: 25/(15+25) ×100

Answer: C / 100 units^2

Step-by-step explanation:

The equation to calculate the area of a rhombus is

[tex]Area = \frac{ab}{2}[/tex]

In the picture, you are given a & b.

a equals the entire vertical line. So 5 + 5 = 10. 10 is a

b equals the entire horizontal line. So 10 + 10 = 20. 20 is b.

According to the equation you multiply a times b.

[tex]Area = \frac{(10)(20)}{2}[/tex]   10 x 20 = 200

200 divided by 2 equals 100

so the areas = 100

Step-by-step explanation:

se você reparar no ângulo interno da figura do octógono está mostrando 135º e a primeira figura que no caso não encaixa mostra 60º, fazendo essa soma daria um total de 195º, o que passa de 180º que é a metade de uma circunferência, então não daria certo, ficaria uma parte sobrando, não se encaixando no mosaico.

Answer:

It’s 4.2

Step-by-step explanation:

Answer:

Vertical intercepts: (-2,pi/2) and (-10,pi/2)

Horizontal intercepts: (4,0) and (-4,0)

Step-by-step explanation:

I took the test and got it right.

The required horizontal intercepts are at approximately (41.81°, 0) and (138.19°, 0), and the vertical intercepts are at (0, 4) and (0, -10).

In the equation intercept is the value of the linear function where either of the variables is zero.

To find the horizontal intercept(s) of the limacon, we need to set r equal to zero and solve for theta.

r = 4 - 6sin(Ф)

0 = 4 - 6sin(Ф)

6sin(Ф) = 4

sin(Ф) = 4/6

sin(Ф) = 2/3

We can use an inverse sine function to find the value of theta:

Ф= sin^-1(2/3)

Ф≈ 41.81° or 138.19°

These are the values of theta where the limacon crosses the x-axis (horizontal intercepts).

To find the vertical intercept(s), we need to set theta equal to zero or pi and solve for r.

When Ф= 0:

r = 4 - 6sin(0)

r = 4

So the limacon intercepts the y-axis at (0, 4).

When Ф= pi:

r = 4 - 6sin(pi)

r = 10

So the limacon intercepts the y-axis at (0, -10).

Therefore, the horizontal intercepts are at approximately (41.81°, 0) and (138.19°, 0), and the vertical intercepts are at (0, 4) and (0, -10).

From the diagram, we can tell that the maximum height that is reached by the barnacle is 1m.

The Barnacle is going around the water level in the shape of a circle which the water level being the diameter.

This means that the maximum height the barnacle can reach is constricted by the radius such that it is the same as the radius of the circle. This means that the maximum height is 1m.
