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.

The inverse function of the given function will be f(x)⁻¹ = ( 10 ) / ( 9x - 99).

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).

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.

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.

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).

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).

The efficiency of the car in unit miles per gallon will be 26.28.

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".

Given

There are 4 yellow, 6 green and 5 blue marbles

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]

Using Indices Law :

[tex] \sqrt{a} \times \sqrt{b} = \sqrt{ab} [/tex]

[tex] \sqrt{ - 6} \times \sqrt{ - 10} [/tex]

[tex] = \sqrt{ - 6 \times - 10} [/tex]
