"What is the theoretical probability of rolling a prime number on a standard number cube?"
Answer:
There are three prime numbers and 3 even numbers on a number cube, so the probability of each is 3/6 = 1/2
Step-by-step explanation:
Probability of rolling a prime number on a standard number cube is [tex]\frac{1}{2}[/tex] or 0.5.
What is theoretical probability?The theoretical probability is defined as the ratio of the number of favorable outcomes to the number of possible outcomes.
Numbers on a cube are {1, 2, 3, 4, 5, 6}
Total number of favorable outcomes = 6
Number of prime numbers in {1, 2, 3, 4, 5, 6} are {2, 3, 5}.
Number of favorable outcomes = 3
Probability of rolling a prime number on a standard number cube
P = [tex]\frac{Number of favorable outcomes}{Total number of favorable outcomes }[/tex]
P = [tex]\frac{3}{6}[/tex]
P = [tex]\frac{1}{2}[/tex]
Hence, probability of rolling a prime number on a standard number cube is [tex]\frac{1}{2}[/tex] or 0.5.

Emery bought three cans of beans I had a total weight of 2.4 pounds each can of beans with the same amount which model correctly illustrates the relationship check all that apply
Answer:
Figure 2 and 3 are correct
Step-by-step explanation:
This question is incomplete, the figures are attached.
Number of cans of beans bought by Emery = 3
Total weight of cans = 2.4 pounds
Therefore the weight of each can = 2.4/4 = 0.8 pounds
The can be represented by the equation:
y = 0.8x, where x is the number of cans and y represents the total weight
From the graph of figure 1, weight of each can = 20/16 = 1.25 pounds. This is not correct
From the graph of figure 2, weight of each can = 8/10 = 0.8 pounds. This is correct
From the table of figure 3, weight of each can = 4/5 = 0.8 pounds. This is correct
From the table of figure 4, weight of each can = 5/4 = 1.25 pounds. This is not correct
A bag contains 19 cards numbered 1 through 19. A card is randomly chosen from the bag. What is the probability that the card has an even number on it? Write your answer as a fraction in simplest form. willllll get brainest
Answer:
[tex]\dfrac{9}{19}[/tex]
Step-by-step explanation:
It is given that there are a total of 19 cards ({1,2,3,4, ...... ,19}).
Let S be the set of total cards.
S ={1,2,3,4, ...... ,19}
Total number of observations, n(S) = 19
Even number of cards is the set {2,4,6,8,10,12,14,16,18}
Total number of cards with even number on it = 9
Let E be the event of selecting a card with even number on it.
n(E) = 9
Probability of an event A can be formulated as:
[tex]P(A) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
In this case, formula of P(E) is:
[tex]P(E) = \dfrac{n(E)}{n(S)}[/tex]
[tex]\Rightarrow \dfrac{9}{19}[/tex]
The probability that the card chosen at random is an even number is:
[tex]\dfrac{9}{19}[/tex]
The probability that the card will have an even number will be 0.4737.
From the information given, we are informed that a bag contains 19 cards numbered 1 through 19. Based on the information, the even numbers will be 2, 4, 6, 8, 10, 12, 14, 16, and 18. Therefore, the probability of having when numbers will be:= 9/19 = 0.4737

Events A and B are mutually exclusive. Find the missing probability.
P(A) = 3/10 P(B) = ? P(A or B) = 4/5
1/2
2/3
1/5
3/10
Answer:
1/2
Step-by-step explanation:
As they are mutually exclusive P(A and B) = 0 therefore the probability of P(A or B)= P(A) + P(B). Just do 4/5-3/10= 5/10=1/2
The value for P(B) is 1/2.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
P(A) = 3/10, P(B) = ?, P(A or B) = 4/5.
As they are mutually exclusive P(A and B) = 0
So, P( A or B)
4/5 = P(A) + P(B)
4/5 = 3/10 + P(B)
P(B) = 4/5 - 3/10
P(B) = 5/10
P(B) = 1/2.

What is the length of a radius of the circle represented by the equation
x2 + y2 - 4x - 4y + 4 = 0?
A) 2 units
B) 4 units
C) 8 units
D) 16 units
Answer:
A) 2 units
Step-by-step explanation:
Given;
x² + y² - 4x - 4y + 4 = 0
Consider general circle equation;
(x - h)² + (y - k)² = r²
where;
(h , k ) is the center of the circle
r is the radius of the circle
x² + y² - 4x - 4y + 4 = 0
subtract 4 from both sides of the equation
x² + y² - 4x - 4y = - 4
square half of coefficient of x and y, and add them to both sides of the equation
x² + - 4x + (-2)² + y² - 4y + (-2)² = - 4 + (-2)² + (-2)²
factorize x and y
(x - 2)² + (y - 2)² = - 4 + 4 + 4
(x - 2)² + (y - 2)² = 4
(x - 2)² + (y - 2)² = 2²
Compare this final equation to general equation of a circle
(x - 2)² + (y - 2)² = 2²
(x - h)² + (y - k)² = r²
r = 2
Thus, the length of a radius of the circle is 2 units

In a running competition, a bronze, silver and gold medal must be given to the top three girls and top three boys. If 15 boys and 4 girls are competing, how many different ways could the six medals possibly be given out?
Answer:
There are a total of possible 1820 results.
Step-by-step explanation:
Since there are two competitions, one for boys and one for girls, and we want all the possible results we will calculate the possible combinations for the boys and multiply them by the possible combinations for the girls. This is shown below:
[tex]Boys = \frac{15!}{3!(15 - 3)!} = \frac{15!}{3!12!} = \frac{15*14*13*12!}{3!12!}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = 455[/tex]
[tex]Girls = \frac{4!}{3!*(4 - 3)!}\\Girls = \frac{4*3!}{3!}\\Girls = 4[/tex]
Total number of possible results:
[tex]results = 4*455\\results = 1820[/tex]

Answer:
Option C; 3x - y = -27 and x + 2y = 16
Step-by-step explanation:
1. Let us consider the equation 21x - y = 9. In this case it would be best to keep the equation in this form, in order to find the x and y intercept. Let us first find to y - intercept, for the simplicity ⇒ 21 * ( 0 ) - y = 9 ⇒ y = - 9 when x = 0. Now if we take a look at the first plot of line q, we can see that the x value is -9 rather than the y value, so this equation doesn't match that of line q. This would eliminate the first two options being a possibility.
2. Now let us consider the equation 3x - y = -27. Let us consider the x-intercept in this case. That being said, ⇒ 3x - ( 0 ) = -27 ⇒ 3x = -27 ⇒ x = -9 when y = 0. As we can see, this coordinate matches with one of the coordinates of line q, which might mean that the second equation could match with the equation for line v.
3. To see whether Option 3 is applicable, we must take a look at the 2nd equation x + 2y = 16. Let us calculate the y - intercept here: ( 0 ) + 2y = 16 ⇒ 2y = 16 ⇒ y = 8 when x = 0. Here we can see that this coordinate matches with that of the second coordinate provided as one of the points in line v. That means that ~ Answer: Option C

A sporting goods factory puts out 98 playground balls in each shipment. Each ball costs $2. What is the total cost of playground balls in three shipments? ENTER NUMBERS ONLY
Answer:
$588
Step-by-step explanation:
As each shipment has 98 balls, to determine the total cost of playground balls in three shipments, you have to multiply 98 for 3. Then, after determine the amount of balls in the three shipments, you have to multiply that for the price of each ball:
Total amount= 98*3= 294
Total cost= 294*$2= $588
The total cost of playground balls in three shipments is $588.
