Bridget, Cassie, and Hannah are discussing the results of their last math test. Hannah shows Bridget and Cassie her test, but Bridget and Cassie don't show theirs to anyone. Cassie says, 'I didn't get the lowest score in our class,' and Bridget adds, 'I didn't get the highest score.' What is the ranking of the three girls from highest to lowest?
Answer:
Based on this I would say Cassie got the highest, then Hannah, then Bridget.
Step-by-step explanation:
Cassie saying that she didn’t get the lowest means that her’s is higher than Hannah’s. The Bridget saying that she didn’t get the highest probably means she got lower than Hannah.
━━━━━━━☆☆━━━━━━━━━━━━━━☆☆━━━━━━━
《Answer》
If Hannah did better than Cassie, there would be no way she could know for sure that she didn't get the lowest score in the class. Therefore, Hannah did worse than Cassie. Similarly, if Hannah did worse than Bridget, there is no way Bridget could have known that she didn't get the highest in the class. Therefore, Hannah did better than Bridget, so our order is
Cassie, Hannah, Bridget

inverse of the letter a
Answer:
We have the function f(x) = 2x + 3
the processes which take place in this function are
we take x [x]
we multiply it by 2 [2x]
we add 3 to it [2x + 3]
To get the inverse of this function, we will do exactly the opposite of it
we will take the output of the initial function [y]
we will subtract 3 from it [y-3]
we will divide it by 2 [(y-3)/2]
We get the function:
[tex]f^{-1}[/tex](y) = (y-3) / 2
Inverse functions are used to get the initial value used in the function bu using the output of the function
[tex]f^{-1}[/tex](0) = (0-3)/2
[tex]f^{-1}[/tex](0) = -3/2
Therefore, the input of the function is -3/2 when the output is 0

Jamal's friends toss 12 balls to him at the same time. Three balls are red, 3 are green, 3 are blue, and 3 are white. Jamal manages to catch 5 of the balls. What is the probability that he catches 2 red balls and 1 ball of each of the other colors?
Answer:
1/4
Step-by-step explanation:
16.66 2/12 invert to decimal
8.33. 1/12 invert into decimal
24.99 adding them up
25/100 = 1/4 round them up then simplify if possible
The probability that he catches 2 red balls and 1 ball of each of the other colors is 150/792.
Given that, total number of balls=12, red number of balls =3, green number of balls=3, blue number of balls =3 and white number of balls =3.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
Here, C(n,r)= n!/r!(n-r)!
Now, C(12, 5)= 12!/5!(12-5)!
= 12!/5!(7)!
= (12×11×10×9×8×7!)/(5×4×3×2×1)×7!
= 3×11×2×3×4
= 792
Now, C(5, 2)= 5!/2!(5-2)!
= 5!/2!(3)!
= 10
Now, C(5, 1)= 5!/1!(5-1)!
= 5
So, he catches 2 red balls and 1 ball of each of the other colors
= 10×5×3
= 150
The probability of an event = 150/792
Therefore, the probability that he catches 2 red balls and 1 ball of each of the other colors is 150/792.

The sum of two numbers is -32. One number is 2 less than the other.
The numbers whose sum is negative 32 will be negative 15 and negative 17.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The sum of the two numbers is -32. One number is 2 less than the other.
Let the two numbers be x and y. Then the equation is given as,
x + y = - 32 ...1
x = y - 2 ...2
From equations 1 and 2, then the value of y will be
y - 2 + y = - 32
2y = - 30
y = - 15
Then the value of x will be given as,
x - 15 = - 32
x = - 17
The numbers whose sum is negative 32 will be negative 15 and negative 17.

Answer:
x = 8
Step-by-step explanation:
There are two ways of answering this:
1.)Supplementary Angles/Linear pair:
(5x- 15) + (20x - 5) = 180°
25x - 20 = 180
25x - 20 +20 = 180 + 20
25x = 200
x = 8
2.) Vertical angles theorem:
(5x - 15) = (3x + 1)
5x - 3x -15 + 15 = 3x - 3x + 1 +15
2x = 16
x = 8

Find the 48th term.
The sequence 5,12, 19, ... is an arithmetic sequence
The 48th term is 334
How to determine the 48th term?The sequence is given as:
5,12, 19, ...
The above sequence is an arithmetic sequence with the following parameters:
First term (a) = 5
Common difference (d) = 7
The nth term of an arithmetic sequence is:
Tn = a + (n - 1) * d

three persons are entering a five storey building.they can go to first floor or second floor or third floor or fifth floor of the building.what is the probability that they will meet in one floor?
The probability that they will meet in one floor is 1/16.
What is the probability that they will meet in one floor?There are 3 people, and 4 possible floors.
Then the probability of going to a given floor is equal to 1 over the total number of floors:
p = 1/4.
So, let's assume that the first person goes to a given floor, for example, the second.
Then we need to find the probability that the second and third persons also go to that same floor, and it is 1/4 for each.
Then the total probability is the product of the individual probabilities:
P = (1/4)*(1/4) = 1/16.
So the probability that they will meet in one floor is 1/16.
