Can someone please explain and help me understand what the problem is saying? If so I’ll mark you brainliest
Answer:
14
Step-by-step explanation:
This can be seen as a arithmetic series. It is the number of girls, let’s say g, plus the number of girls plus five boys. Deena, can be viewed as 1, plus 5 equals 6. Then Chloe, 2, plus 5 equals 7. And so on and on.
We can create an equation for this:
g+(g+5)=s
(s is the number of students.)
‘If the total number of students is 23;
g+(g+5)=23
We can solve this for:
2g = 23-5 ⇒
g=9
So the number of girls is 9, th number of boys is simply:
23-9=14

Determine the following probabilities. Enter your final answers as reduced fractions. Two coins are flipped. Find the probability that the first coin land on heads and the second coin lands on heads. Two cards are drawn from a deck of 52 cards. The first card is replaced before drawing the second card. Find the probability that the first card is hearts and the second card is a Jack. A single digit between 0 and 9 is randomly chosen, and a single letter from A to Z is randomly chosen. Find the probability that the number is 3 and the letter is a consonant. Two dice are rolled. Find the probability that first die lands on an even number and the second die is less than 3 .
Probabilities are used to determine the chances of events
(a) Coins
In a coin, the probability of the likely outcomes in each flip are:
Head = 1/2
Tail = 1/2
So, the probability that the first lands on head, while the second lands on tail is:
[tex]\mathbf{Pr = \frac 12 \times \frac 12}[/tex]
[tex]\mathbf{Pr = \frac 14}[/tex]
The probability that the first lands on head, while the second lands on tail is 1/4
(b) Deck of cards
There are 52 cards in a deck, 13 of which are hearts while 4 are jack.
The probability that the first card is heart is 13/52
The probability that the second card is jack is 4/51
So, the probability that the first selected card is heart, while the second is jack is:
[tex]\mathbf{Pr = \frac{13}{52} \times \frac{4}{51}}[/tex]
[tex]\mathbf{Pr = \frac{1}{51}}[/tex]
The probability that the first selected card is heart, while the second is jack is 1/51
(c) Digits and Letters
There are 10 digits between 0 and 9, so the probability of selecting 3 is 1/10.
There are 21 consonants, so the probability of selecting a consonant is 21/26
So, the probability of selecting 3 and a consonant is:
[tex]\mathbf{Pr = \frac{1}{10} \times \frac{21}{26}}[/tex]
[tex]\mathbf{Pr = \frac{21}{260}}[/tex]
The probability of selecting 3 and a consonant is 21/260
(d) Dice
There are 3 even numbers on a die; so the probability of landing on an even number is 3/6
There are 2 numbers less than 3 on a die; so the probability of landing on a number less than 3 is 2/6
So, the probability of landing on an even number and a number less than 3 is:
[tex]\mathbf{Pr = \frac 36 \times \frac 26}[/tex]
[tex]\mathbf{Pr = \frac 16}[/tex]
The probability of landing on an even number and a number less than 3 is 1/6

Đơn giản các biểu thức logic:
a- p ∧ (p ∨¬q) ∧ (¬p ∨ ¬q)
I can't conveniently copy the logical symbols you use, so I write
AND = ∧ (conjunction)
OR = ∨ (disjunction)
NOT = ¬
Tautologically,
p = (p AND q) OR (p AND NOT q)
and we can distribute the OR to get the equivalent statement
(p OR (p AND NOT q)) AND (q OR (p AND NOT q))
and again to get
((p OR p) AND (p OR NOT q)) AND ((p OR q) AND (q OR NOT q))
Now, q OR NOT q is always true, and p OR p is simply p, so we have
p = p AND (p OR q) AND (p OR NOT q)
This shows that p OR NOT q is already included in p, so our initial statement is simply
p AND (NOT p OR NOT q)
Distributing the conjunction, we get
(p AND NOT p) OR (p AND NOT q)
p AND NOT p is tautologically false, but we're considering a disjunction, so the truth value of p AND NOT q is the only value that's relevant. So, the initial statement collapses to
p AND NOT q

What are rational numbers?It should be noted that rational numbers are the numbers that are expressed as the ratio of two integers.
It should be noted that they can be fractions, integers, decimals,etc. Examples include 5, 3.7, 1/5, etc.
A rational number is one that can be written as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively. For instance, every integer and 3/7 are rational numbers.
A real number that cannot be expressed as a straightforward fraction is referred to as an irrational number. It cannot be described using a ratio. When p and q are integers and q is not equal to 0, N is not equal to p/q if N is irrational.

the length of one base of a trapezoid is 7mm less than twice the length of the other base. the height of the trapezoid is 12mm. the area of thr trapezoid is 48mm. find the length in millimeters of the longer base. (please show step by step)
Answer:
Step-by-step explanation:
let x be the length of one base in mm
The other base will be 2x - 7 mm
I will ASSUME you mean the area is 48 mm²
Area of a trapezoid is the Average base length times height
A = ½(x + (2x - 7))h
A = ½(3x - 7)h
2A/h = 3x - 7
2A/h + 7 = 3x
x = (2A/h + 7)/3
x = 2A/3h + 7/3
x = 2(48)/3(12) + 7/3
x = 5 mm
the other length is
2(5) - 7 = 3 mm
Grayson charges $35 per hour plus a $35 administration fee for tax preparation. IAn chargers $45 per hour plus a 15$ administration fee. If h represents the number of hours of tax preparation,for what number of hours does Grayson charge more than Ian
Answer:
Step-by-step explanation:
We translate Grayson's charges through the following mathematical expression : 35 h + 35 where h is the number of hours while that of Ian is 45h + 15. The number of hours where the charges are equal is 35h + 35 = 45h + 15; h = 2 hrs. Hence the number of hours minimum must be above 2 hours.

May I revive help please
Answer:
8500m
Step-by-step explanation:
t = 15 + 0.01 h
t = 100 (given in the question)
∴ 100 = 15 + 0.01 h
100 - 15 = 0.01 h
85 = 0.01 h
85 / 0.01 = h
8500 / 1 = h
8500 = h
The relationship between the number of apples and their weight is proportional. The weight of 5 apples is 0.6kg. How many apples would you expect to weigh 1.44kg?
Answer:
12 apples
Step-by-step explanation:
5 apples = 0.6kg
1 apple = 0.12kg
x = 0.6kg x 2
= 1.2kg (10 apples)
y = 1.44kg - 1.2kg
= 0.24kg (2 apples)
Apples = x + y
= 10 + 2 apples
= 12 apples (weigh 1.44kg)
Your friend claims that the SAS Congruence Theorem (Theorem 5.5) will apply to a triangle and it’s image after the triangle has been translated, reflected, rotated, and dilated. Is your friend correct?
The triangles would not be congruent since it was dilated.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Rigid transformation are transformation that preserve the shape and size of the figure. These are rotation, reflection, and translation. Dilation is not a rigid transformation because it reduces or increases the size of the figure.
Two triangles are congruent if they have the same shape and size.
The triangles would not be congruent since it was dilated.

Answer:
x²-6x+y²-4y=-4
Step-by-step explanation:
We know the circle equation stands like this:
(x-a)² + (y-b)² = R²
and (a,b) is center
and R stands for Radius
so in this case:
center = (3,2)
R = 3
So
(x-3)² + (y-2)² = 9
x²-6x+9 + y²-4y+4=9
x²-6x+y²-4y=-4

Step-by-step explanation:
7x + 3x - 18= 6(x+3)
7x + 3x = 10x - 18 = 6(x+3)
10x - 18 = 6(x+3) convert that into (distribute) 6x + 18
+18 +18 (add 18 to both sides)
