Answer:
1/24
Step-by-step explanation:
1/24 bc there is 24 students in the class and the teachercould only choose 1 student
The two different ways that rolling a six-sided die could be used to simulate the probability that Trevor's teacher will select a boy or girl are:
- Assign one gender to even numbers and the other gender to odd numbers.
- Assign each student a number from 1 to 24, and then divide the numbers into two groups.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
To simulate the probability of selecting a boy or girl from Trevor's math class,
We can use a six-sided die in two different ways:
- Assign one gender to even numbers and the other gender to odd numbers.
For example, we can assign boys to even numbers (2, 4, 6) and girls to odd numbers (1, 3, 5).
We would then roll the die, and if it lands on an even number, we would consider the selected student to be a boy, and if it lands on an odd number, we would consider the selected student to be a girl.
We can repeat this process multiple times to simulate the probability of selecting a boy or girl.
- Assign each student a number from 1 to 24, and then divide the numbers into two groups:
one group for boys and the other group for girls.
For example, we can assign the boys the numbers 1 to 12 and the girls the numbers 13 to 24.
We would then roll the die and select the student with the corresponding number.
If the number is between 1 and 12, we would consider the selected student to be a boy, and if the number is between 13 and 24, we would consider the selected student to be a girl.
We can also repeat this process multiple times to simulate the probability of selecting a boy or girl.
Thus,
The two different ways that rolling a six-sided die could be used to simulate the probability that Trevor's teacher will select a boy or girl are:
- Assign one gender to even numbers and the other gender to odd numbers.
- Assign each student a number from 1 to 24, and then divide the numbers into two groups.

You estimate that there are 73 marbles in a jar. The actual amount is 59 marbles. Find the percent error. Round to the nearest tenth of a percent if necessary.
Answer:
23. 7%
Step-by-step explanation:
You're gonna use the percent error formula and plug in yoru values for it.
lactual value - expected value/expected valuel x 100
l59 - 73/73l x 100
14/59 x 100
= 23.728813559322%
rounded it'd be 23. 7%
ten athletes ran two races of the same length. The scatter plot shows their times. Select all statements that are true.
The scatter plot has been attached
Answer:
Options C, D & E are true
Step-by-step explanation:
Option A is wrong because from the scatter plot, only four athletes were faster in the second race than in the first one.
Option B is wrong because only 1 athlete had his second race time differing from the first race time by exactly 2 seconds.
Option C is true because exactly 9 of the times for the first race were at least 16 seconds
Option D is true because there are exactly 3 athletes who had the same time in both races
Option E is true because 8 of the times for the second race were less than 17 seconds

Locate the Fourth Vertex
Quadrilateral BDFH is constructed so that each vertex is on a different side of
square ACEG. Vertex B is on side AC so that AB = 4 cm and BC = 6 cm.
Vertex F is on EG so that EF = 3 cm and FG = 7 cm. Vertex H is on GA so
that GH = 4 cm and HA= 6 cm. The area of quadrilateral BDFH is 47 cmº.
The fourth vertex of quadrilateral BDFH, labelled D, is located on side CE so
that the lengths of CD and DE are both positive integers.

can someone please help me find the answer to this they want me to find the surface area of it
Answer:
Step-by-step explanation:
You have three rectangular faces and two triangular faces. Each rectangular face has an area equal to xy. Each triangular face has an area equal to xy/2. So the total area will be
A=5(7)+3(7)+4(7)+4(3)/2+4(3)/2
A=35+21+28+6+6
A=96cm^2
Answer:
as below
Step-by-step explanation:
add up the surface area of each side of this object
this object has 5 sides
2 of the sides are equal triangles so we could add those up to make one whole rectangle. and if we do that then there are only 4 sides
the two triangle sides add up to one rectangle side of 4 *3 = 12
the bottom side facing downwards = 3 * 7 = 21
the back side facing away = 4 * 7 = 28
the front side at an angle = 7 * 5 = 35
12 + 21 + 28 + 35 = 96 [tex]cm^{2}[/tex]

Answer:
5 felt pads.
7 cards.
Step-by-step explanation:
Remark
The total number of items is 12 So let the felt sheets be xLet the cards = yEquations and Solution
x + y = 12
Now the price is 7.75 that she has to pay for the 12 items. She wants to come back with 0 dollars.
0.5x + 0.75y = 7.75 Multiply this equation by 2
x + 1.5y = 15.50 write the first equation underneath and subtract.
x + y = 12
.5y = 3 Divide by 0.5
y = 3/0.5
y = 7
So she can get 7 cards.
x + y = 12
x + 7 = 12
x = 12 - 7
x = 5
So she can buy 5 felt pads.

A bag contains 2 red pens, 4 blue pens, 3 black pens, and 1 green pen. Once a pen is selected, it is replaced, and then another pen is selected. Determine P(blue and blue)
Given:
A bag contains 2 red pens, 4 blue pens, 3 black pens, and 1 green pen.
Once a pen is selected, it is replaced, and then another pen is selected.
To find:
The probability of getting blue pens in both draws, i.e., P(blue and blue).
Solution:
We have,
Number of red pens = 2
Number of blue pens = 4
Number of black pens = 3
Number of green pen = 1
Total number of pens = [tex]2+4+3+1[/tex]
= [tex]10[/tex]
The probability of getting a blue pen is:
[tex]P(\text{Blue})=\dfrac{\text{Number of blue pens}}{\text{Total number of pens}}[/tex]
[tex]P(\text{Blue})=\dfrac{4}{10}[/tex]
[tex]P(\text{Blue})=0.4[/tex]
Once a pen is selected, it is replaced, and then another pen is selected. So, after replacement the probability of getting a blue is remains the same.
[tex]P(\text{Blue and Blue})=P(\text{Blue})\times P(\text{Blue})[/tex]
[tex]P(\text{Blue and Blue})=0.4\times 0.4[/tex]
[tex]P(\text{Blue and Blue})=0.16[/tex]
Therefore, the value of [tex]P(\text{Blue and Blue})[/tex] is 0.16.
