Answer:

-257

Step-by-step explanation:

Answer:

The sequence is increasing by 5 at each step. So, we can write:

a1 = 30

a2 = 30 + 5 = 35

a3 = 30 + 25 = 40

a4 = 30 + 35 = 45

a5 = 30 + 4*5 = 50

We notice that the nth term is given by:

an = 30 + (n-1)5

So, the explicit formula for the nth term is:

an = 25n + 5

The calculated value of the probability of B is (c) 0.25

From the question, we have the following parameters that can be used in our computation:

P(A or B) = 0.3

P(A and B) = 0.2

P(A/B) =0.8

First, we have

P(A/B) = P(A and B)/P(B)

Substitute the known values in the above equation, so, we have the following representation

0.2/P(B) = 0.8

So, we have

P(B) = 0.2/0.8

Evaluate

P(B) = 0.25

Hence, the probability of B is 0.25

If Fran and Jill made a new years resolution to ride bikes.  it will take 3 weeks for Fran and Jill to have ridden the same number of miles..

Let's assume that it takes "x" number of weeks for Fran and Jill to ride the same number of miles.

In the first week, Fran rides 40 miles, and Jill rides 70 miles.

In the "x"th week, Fran will have ridden a total of 40 + 55x miles.

In the "x"th week, Jill will have ridden a total of 70 + 45x miles.

For Fran and Jill to ride the same number of miles in "x" weeks, we need to solve the following equation:

40 + 55x = 70 + 45x

Simplifying this equation, we get:

10x = 30

x = 3

Therefore, it will take 3 weeks for Fran and Jill to have ridden the same number of miles.

Answer:

40

Step-by-step explanation:

Lets put the 3/4 at the beginning and expand this bracket :

3/4(x-4) = 27

3/4x - 3 = 27

Now we add 3 to both sides :

3/4x = 30

Now we times both sides by 4 :

3x = 120

Now we divide both sides by 3:

x = 40

The value of x that makes the perimeter of the rectangles the same is 7.

The perimeter of a figure is the sum of the whole sides of the figure.

In other word, the perimeter of a shape is defined as the total length of its boundary.

The two figures are rectangle. Let's find the perimeter of the rectangles as follows:

The question says let's find the value of x that makes the perimeter the rectangles the same.

perimeter of a rectangle = 2(l + w)

where

Therefore,

2(x + x + 3) = 2(14 + x - 4)

2(2x + 3) = 2(10 + x)

4x + 6 = 20 + 2x

4x - 2x = 20 - 6

2x = 14

divide both sides by 2

x = 14 / 2

x = 7

Therefore, the value of x is 7

The number she'd have is:

Explanation:

First, let's see which number is in the tens place and which number is in the ones place (the units place).

In the number 548, the place value of 5 is hundreds, the place value of 4 is tens, and the place value of 8 is ones (or units).

So if Sera adds two to the units, she'll have 10. But, since we can't write the number as 5410 (that would be a totally different number), we just write 0 in the units place, and shift 1 to the tens place, which gives us :

550

That's not all, since we also add 1 to the tens:

The predicted relationship between X is $0.375. Let X be the random variable representing the winnings from this game. We know that: If three tails are obtained, the winnings are $6.

If three tails are not obtained, the winnings are -$2.

The probability of getting three tails is 1/8. Therefore, the probability of not getting three tails is:

P(not getting three tails) = 1 - P(getting three tails) = 1 - 1/8 = 7/8

Now we can calculate the expected value of X using the formula:

E(X) = (winnings from getting three tails) * P(getting three tails) + (winnings from not getting three tails) * P(not getting three tails)

E(X) = ($6) * (1/8) + (-$2) * (7/8)

E(X) = $0.375

Therefore, the expected value of X is $0.375.

Answer:

The graph that shows the translation f(x) = f(x) + 1 is the graph that is shifted upward by one unit on the y-axis. All the points on the graph have been moved upward by one unit, but the shape of the graph remains the same as the parent function.

The dotted line graph that shows the translation f(x) = f(x) + 1 is the one where the graph is shifted upward by one unit on the y-axis.

Answer:

C. Zach's

Step-by-step explanation:

To solve the equation 7(x + 3) = 7(x + 5), we can start by simplifying both sides of the equation:

7x + 21 = 7x + 35

Subtracting 7x from both sides, we get:

21 = 35

This is a contradiction, as 21 is not equal to 35. Therefore, the equation has no solution.

However, the problem states that the equation has an infinite number of solutions. This can only happen if the missing number is a factor that appears on both sides of the equation, and therefore cancels out when we simplify the equation.

Looking at the equation, we can see that both sides have a factor of 7, which cancels out when we simplify the equation. Therefore, the missing number must be the factor that was torn off, which is 7 multiplied by the difference between the two numbers inside the parentheses:

7(5 - 3) = 14

Therefore, the missing number is 14, which corresponds to answer option B.

Answer: When a chemical is heated, its temperature increases.

Explanation:

When its temperature increases, the reactants have more kinetic energy so the frequency of effective collision increases, resulting in a faster rate of chemical reaction.

Answer:

x = - 6

Step-by-step explanation:

x² + 12x + 36 = 0 ( subtract 36 from both sides )

x² + 12x = - 36

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(6)x + 36 = - 36 + 36

(x + 6)² = 0 ( take square root of both sides )

x + 6 = \(\sqrt{0}\) = 0 ( subtract 6 from both sides )

x = - 6

Abe's model is similar to Jenna's model in the number of possible outcomes in the sample space, and in that the P(white) = 1/2.

Given - Abe has the following spinner:

(the image below)

Jenna's spinner had 3 white sections, 1 yellow section, 1 blue section, and 1 red section.

To find - How his probability model will differ from Jenna's model?

This question can be answered by observing differences and similarities between Jenna's and Abe's spinners in terms of the sample space and probabilities of each color.

The models differ in that, the probability of the two events is the same in Abe's model, but the probability of all four events in Jenna's model is not the same.

Step 1

In Abe's spinner, the Sample space, S is three white sections and three blue sections adjacent to each other.

The list of events and their probabilities is:

P(white) = 1/2

P(blue) = 1/2

Thus, Abe's model is similar to Jenna's model in the number of possible outcomes in the sample space, and in that the P(white) = 1/2.

The value of cos(2α + β) using trigonometric identities is; -1.0155

We are given;

α = sin⁻¹(4/5)

β = tan⁻¹(12/5)

Thus;

sin α = 4/5

tan β = 12/5

From trigonometric ratios, we can say that;

cos α = 3/5

sin β = 12/13

cos β = 5/13

We know from trigonometric identities that  cos (a + b) = cos a cos b - sin a sin b.

Thus;

cos(2α + β) = cos 2α cos β - sin 2α sin β

Thus;

cos(2α + β) = 2(3/5) * (5/13)) - ((2 * 4/5 * 12/13))

What in mathematics is a linear equation?

An algebraic equation with simply a constant and a first-order (linear) component, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

                         Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables. Equations whose variables have a power of one are called linear equations. A single variable example with real values for a and b and x as the variable is ax+b = 0.

Answer:

59 accidents were investigated.

Step-by-step explanation:

The question above is a probability question that involves 2 elements: causes of accidents.

Let

A = Alcohol

E = Excessive speed

In the question, we are given the following information:

18 accidents involved Alcohol and Excessive speed =P(A ∩ E)

26 involved Alcohol = P(A)

12 accidents involved excessive speed but not alcohol = P( E ) Only

21 accidents involved neither alcohol nor excessive speed = neither A U B

We were given P(A) in the question. P(A Only) = P(A) - P(A ∩ E)

P(A Only) = 26 - 18

= 8

So, only 8 accident involved Alcohol but not excessive speed.

The Total number of Accidents investigated = P(A Only) + P( E only) + P(A ∩ E) + P( neither A U B)

= 8 + 12 + 18 + 21

= 59

Therefore, 59 accidents were investigated.

Answer:

wouldnt it be 13? and do you have have ps3

Substitute \(u=x^2+4\) and \(du=2x\,dx\). Then the integral transforms to

\(\displaystyle \int \frac{x\,dx}{(x^2+4)^3} = \frac12 \int \frac{du}{u^3}\)

Apply the power rule.

\(\displaystyle \int \frac{du}{u^3} = -\dfrac1{2u^2} + C\)

Now put the result back in terms of \(x\).

\(\displaystyle \int \frac{x\,dx}{(x^2+4)^3} = \frac12 \left(-\dfrac1{2u^2} + C\right) = -\dfrac1{4u^2} + C = \boxed{-\dfrac1{4(x^2+4)^2} + C}\)
