You spin the spinner twice find the probability of spinning a 3 then a 4
Answer:
X represents the total numbers on the spinner.
1 1
_ times _
X. X
Final answer:
To find the probability of spinning a 3 and then a 4, we calculate the individual probabilities of each event (1/6 each) and multiply them, resulting in a combined probability of 1/36.
Explanation:
The question asks about the probability of spinning a 3 followed by a 4 on a spinner. Assuming the spinner has equal sections numbered from 1 to 6, similar to a six-sided die, we can calculate the probability of each individual spin and then combine them to find the overall probability of the sequence happening.
The probability of spinning a 3 on the first spin is 1/6, and similarly, the probability of spinning a 4 on the subsequent spin is also 1/6. Since these two events are independent, we multiply these probabilities to find the combined probability of both events happening in sequence:
Probability of spinning a 3 then a 4 = Probability of 3 on first spin × Probability of 4 on second spin
= (1/6) × (1/6)
= 1/36
Therefore, the probability of spinning a 3 and then a 4 in two spins is 1/36.

How long would it take a bus traveling at 52 km/h to travel 130 km ??
Answer: 2.5 hours
Step-by-step explanation:
130 / 52 = 2.5
A bus will take "2.5 hours" to travel.
Given that:
Speed of bus (s),
= 52 km/h
Distance (d),
= 130 km
As we know,
→ [tex]Speed = \frac{Distance}{Time}[/tex]
or,
→ [tex]Time = \frac{Distance }{Speed}[/tex]
By substituting the values, we get
[tex]=\frac{130}{52}[/tex]

1/3 of the difference of 20 and 2
Answer:
the correct answer is 6
Step-by-step explanation:
hope it helps !
To find 1/3 of the difference of 20 and 2, subtract 2 from 20 to get the difference, then divide the difference by 3.
Explanation:To determine one-third of the difference between 20 and 2, we first find the difference itself, which is 20 - 2 = 18. Then, recognizing that one-third represents dividing by 3, we divide the difference, 18, by 3, resulting in 18 ÷ 3 = 6. This mathematical process illustrates the sequential steps taken to solve the problem. The method involves subtraction to identify the difference and subsequent division by 3 to find the desired fraction. This systematic approach ensures clarity in understanding the solution. Hence, one-third of the difference between 20 and 2 equals 6, demonstrating the application of basic arithmetic concepts in solving real-world problems and enhancing mathematical reasoning skills.

Answer:
hope this helps!
Step-by-step explanation:
The inverse function of the given function will be f(x)⁻¹ = ( 10 ) / ( 9x - 99).
What is an inverse function?A function is defined as the expression that set up the relationship between the dependent variable and the independent variable. In an inverse function, the value of two variables x and y are interchanged, and then the value of y is given an inverse function.
Given function is f(x) = ( 10/9x) + 11. the inverse function will be calculated as below:-
y = 10/9x+11
x = ( 10 / 9y ) + 11
x - 11 = ( 10 / 9y )
9y / 10 = ( 1 / ( x - 11 )
9y = 10 / ( x - 11 )
y = ( 10 ) / ( 9x - 99 )
Therefore, the inverse function of the given function will be f(x)⁻¹ = ( 10 ) / ( 9x - 99).

We have to find [tex]P(B\mid A)[/tex] i.e. conditional probability of B given that A is occurred.
[tex]P(B\mid A)[/tex] is given by
[tex]P(B\mid A)=\dfrac{P(A\cap B)}{P(A)}[/tex]
Also A=drawing a green marble
B=drawing a yellow marble
Total no of marbles [tex]=4+6+5=15[/tex]
So,
[tex]P(A)=\dfrac{6}{15}[/tex]
similarly [tex]P(B)=\dfrac{4}{15}[/tex]
[tex]P(A\cap B)=P(A)\times P(B)[/tex]
[tex]P(A\cap B)=\dfrac{6}{15}\times \dfrac{4}{15}[/tex]
[tex]P(A\cap B)=\frac{24}{225}[/tex]
Substituting the values in the formula
[tex]P(B\mid A)=\dfrac{\frac{24}{225}}{\frac{6}{15}}[/tex]
[tex]P(B\mid A)=\frac{24}{6}\times \frac{15}{225}[/tex]

Metric countries rate the fuel efficiency of a car by the number of liters of gasoline required to drive 100 kilometers. If a car takes 9 liters per 100 kilometers, what is its efficiency in miles per gallon? Use the conversions 1 gal= 3.7854 L and 1 mile = 1.6 km.
WILL MARK BRAINLIEST
The efficiency of the car in unit miles per gallon will be 26.28.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
Given that,
The car takes 9 liters per 100 kilometers
9 liters ⇒ 100 km
Since 1 gal= 3.7854 L → 1 L = (1/3.7854) gal
9 L = (9/3.7854) gal
1 mile = 1.6 km → 1 km = (1/1.6) miles
100 km = (100/1.6) miles
So, (9/3.7854) gal ⇒ (100/1.6) miles
Efficiency = (100/1.6) ÷ (9/3.7854)
Efficiency = 26.28 miles/gal
Hence "The efficiency of the car in unit miles per gallon will be 26.28".

The interior angles in a triangle have a sum of 180 degrees. You can also prove it by the Sum of Interior Angles formula:
S= (n-2)·180.
n- the number of sides in the polygon
S= the total sum of interior angles.

Factor completely and then place the factors in the proper location on the grid. 4 y^2 + 25 y + 6
Answer:
Hello There. I think the Correct answer is (4y+1)(y+6)
Step-by-step explanation:
Well I can't grid it for you, you didn't get give enough detail, however I can do the factoring.
Step-by-step explanation:
Given equation [tex]4y^{2} + 25y + 6[/tex][tex]4y^{2} + 25y + 6[/tex]
We have to write the given equation in factors form and then represent the factors on grid.
Consider the given equation [tex]4y^{2} + 24y + y + 6[/tex]
25y can be written as 24y + y , we get
⇒ [tex]4y^{2} + 24y + y + 6[/tex]
Taking 4y common from first two term and 1 common from last two term, we get,
⇒ [tex]4y(y + 6) + 1 (y + 6)[/tex]
⇒ [tex](4y + 1) (y + 6)[/tex]
Thus, factored form of given equation [tex]4y^{2} + 25y + 6 (4y + 1) (y + 6)[/tex]
Hope it helps!
From ItsNobody
The quadratic expression 4y^2 + 25y + 6 is factored by finding two numbers that multiply to 24 (product of A and C) and add up to 25 (the middle coefficient B). These numbers are 24 and 1, which leads to factoring the expression as (4y + 1)(y + 6).
Explanation:To factor the quadratic expression 4y^2 + 25y + 6, we will use the method of factoring by grouping or the AC method, where 'A' is the coefficient of the squared term and 'C' is the constant term.
Step 1: Multiply 'A' and 'C' (4 * 6 = 24) and find two numbers that multiply to 24 and add up to 'B' (the coefficient of the y term, which is 25).
Step 2: After finding the numbers 24 and 1 (since 24 * 1 = 24 and 24 + 1 = 25), rewrite the middle term (25y) as 24y + y.
Step 3: The expression now looks like 4y^2 + 24y + y + 6. Group the terms to factor by grouping: (4y^2 + 24y) and (y + 6).
Step 4: Factor out common terms from each group: 4y(y + 6) + 1(y + 6).
Step 5: Now that we have a common factor of (y + 6), the expression can be written as (4y + 1)(y + 6).
