math class has 6 girls and 2 boys in the seventh grade and 3 girls and five boys in the right grade. the teacher randomly selects a 7th and a 8th grader. What is the probability that the student she selects are both girls
To find the probability of selecting two girls, multiply the probability of selecting a girl from the 7th grade class by the probability of selecting a girl from the 8th grade class.
Explanation:To find the probability that the teacher selects two girls, we need to determine the probability of selecting a girl from the 7th grade class and the probability of selecting a girl from the 8th grade class, and then multiply those probabilities together.
Probability of selecting a girl from the 7th grade class = Number of girls in 7th grade class / Total number of students in 7th grade class = 6 / (6+2) = 6/8 = 3/4 = 0.75
Probability of selecting a girl from the 8th grade class = Number of girls in 8th grade class / Total number of students in 8th grade class = 3 / (3+5) = 3/8 = 0.375
Probability of selecting two girls = Probability of selecting a girl from 7th grade class * Probability of selecting a girl from 8th grade class = 0.75 * 0.375 = 0.28125
Final answer:
The probability of selecting two girls, one from each grade, is 9/32.
Explanation:
The probability of selecting a girl from the seventh-grade class is 6/8, since there are 6 girls out of 8 total students. Similarly, the probability of selecting a girl from the eighth-grade class is 3/8. Since the two events are independent of each other, we can multiply the probabilities to find the probability of selecting a girl from both grades.
So, the probability of selecting a girl from the seventh grade AND a girl from the eighth grade is (6/8) * (3/8) = 18/64 = 9/32.
Therefore, the probability that the teacher selects two girls is 9/32.

what is 16 - 5y = 1 - 4y
The solution to the equation 16 - 5y = 1 - 4y is y = 15.
Here, we have,
To solve the equation 16 - 5y = 1 - 4y, you can follow these steps:
Step 1: Combine like terms on both sides of the equation.
16 - 5y = 1 - 4y
Step 2: Simplify by subtracting 1 from both sides.
16 - 5y - 1 = 1 - 4y - 1
15 - 5y = -4y
Step 3: Simplify further by subtracting -4y from both sides.
15 - 5y + 4y = -4y + 4y
15 - y = 0
Step 4: Isolate the variable term by subtracting 15 from both sides.
15 - y - 15 = 0 - 15
-y = -15
Step 5: Multiply both sides by -1 to solve for y.
-y * -1 = -15 * -1
y = 15
Therefore, the solution to the equation 16 - 5y = 1 - 4y is y = 15.

a worker is tiling the floor of a rectangular room that is 12 feet by 15 feet. THe tiles are square with side lengths 1 1/3 feet. How many tiles are needed to cover the entire floor?
Answer:
102 tiles needed to cover the entire floor.
Step-by-step explanation:
Given : A worker is tiling the floor of a rectangular room that is 12 feet by 15 feet. The tiles are square with side lengths [tex]1\frac{1}{3}[/tex] feet.
To find : How many tiles are needed to cover the entire floor?
Solution :
A rectangular room that is 12 feet by 15 feet.
The area of the room is [tex]A=L\times B[/tex]
[tex]A_r=15\times 12[/tex]
[tex]A_r=180\ ft^2[/tex]
The tiles are square with side lengths [tex]1\frac{1}{3}=\frac{4}{3}[/tex] feet.
The area of the tile is [tex]A_t=s^2[/tex]
[tex]A_t=(\frac{4}{3})^2[/tex]
[tex]A_t=\frac{16}{9}\ ft^2[/tex]
Number of tiles needed to cover the entire floor is
[tex]n=\frac{A_r}{A_t}[/tex]
[tex]n=\frac{180}{\frac{16}{9}}[/tex]
[tex]n=\frac{180\times 9}{16}[/tex]
[tex]n=101.25[/tex]
Therefore, Approximately 102 tiles needed to cover the entire floor.

A number cube is rolled and a random chip is pulled from a bag of 6 different color chips. The number cube is labeled 1 to 6. There is one blue chip in the bag. What is the probability of the number cube landing on an even number and a blue chip being drawn? Enter your answer as a fraction in simplest form in the box.
Answer:
The probability of an even number being drawn is 1/3 because the cube is numbered 1-6. The even numbers 1-6 are 2,4, and 6.
The probability of it landing on a blue is 1/6. Since there are six different colored chips and one is blue that means there is a 1/6 chance that a blue to be drawn.
Together, the probability of a number cube landing on an even number AND a blue chip being drawn is 1/12.

Which statement best describes the value of 8
The question relates to the process of rounding numbers, a fundamental concept in mathematics where 8 usually causes an increase in the value of the digit before it.
Explanation:Based on the information provided in the question, it appears to be related to the concept of rounding numbers in mathematics. Rounding is a mathematical procedure used to shorten a number to a certain number of significant digits or a certain decimal place. When you round the number 8, it can impact the number it is associated with, such as rounding numbers up in the case of 5 or greater, or keeping them the same if the digits are less than 5. For example, if a 1 is followed by an 8, rounding replaces the 1 with a 2. If an integer, such as 2, is followed by an 8 and we're dropping decimal places, the 2 may be dropped. In the case of aesthetics or grades, the number 8 might have a different interpretation, such as the value given on an 8-point scale.
