Step-by-step explanation:

Don't make life difficult with decimals. First multiply both sides with 10 to get rid of decimals.

10 (3x^2 + 2.5x) = 10 (12.5)

30x^2+ 25x = 125 (now rearrange to write in quadratic form)

30x^2 + 25 x - 125 = 0 (now we know a = 30, b= 25, c = -125)

Final answer x = 5/3 , -5/2

For a one-week period, three bus routes were observed. The results are shown in the table below.

On-Time Delayed Total
Bus Route A 28 7 35
Bus Route B 37 8 45
Bus Route C 24 6 30
Total 89 21 110
A bus is selected randomly. Which event has the highest probability?

A.
The bus is from route B and is delayed.
B.
The bus is from route A and is on time.
C.
The bus is from route C and is on time.
D.
The bus is from route C and is delayed.

Answers

Using it's concept, the event that has the highest probability is given as follows:

B. The bus is from route A and is on time.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

We have that out of the 110 buses, 8 are delayed from route B, hence:

P(A) = 8/110.

28 are on time from route A, hence:

P(B) = 28/110.

24 are on time from route C, hence:

P(C) = 24/110.

6 are delayed from route C, hence:
P(D) = 6/110.

Hence option B gives the highest probability.

Answers

Answer:

Step-by-step explanation:

You want the diameter of a cylinder if the stroke length is 4.5 in, and 6 of them have a volume of 400 in³.

Formula

Filling the given values into the formula, we have ...

  400 = π/4(d²)(4.5)(6)

  d² = 400(4)/(4.5·6π) . . . . . . . . . divide by the coefficient of d²

  d = 40/(3√(3π)) ≈ 4.34 . . . . . . . take the square root

The diameter is about 4.34 inches.

There are more than one solution of the equation. The solution of the equation when solved for y are 5, 2.5-4.3301i, 2.5+4.3301i.

How to find one solution of equation?

If the equation is given a unique and single value of variable after solving, then the equation is said one solution equation. Such equation gives exactly one solution.

The three solution of an equation are-

One solution- When the graph provides the single value of the given variable, we get one or unique solution.No solution- When the graph of equations is equal than it provides the no solution. When the value, does not equate for the expression, then the expression has no solution.Infinite many solution-For the same line, the equation has the infinite many solution.

The expression for y is given as,

y³=125

Here, y is a real number. equate the equation to zero,

y³-125=0

y³-5³=0

Use the formula of difference of two perfect cube as,

(y-5)(y²+5y+25)=0

The values of y we get after solving the equation as,

y=5, 2.5-4.3301i, 2.5+4.3301i

Answer:

Area of shaded region = 6.88 square inches

Step-by-step explanation:

Area of shaded region

  When we subtract the area of the circle from the area of square, we get the area of the 4 corners. When we divide that by 2, we get the area of 2 corners(shaded).
[tex]\sf \boxed{\text{Area of the shaded region =$\dfrac{Area \ of \ square - area \ of \ circle}{2}$}}[/tex]

Square:

Area of square = side *side

                          = 8 * 8

                          = 64 square inches

Circle:

     diameter of the circle = side of the square

                                     d = 8 in

                                      r = 8/2 = 4 in

   [tex]\sf \text{Area of circle = \pi r^2}[/tex]  Area of circle = πr²

If a cat falls out of a tree, it has a probability of 0.92 that it will land
on its feet. If a cat climbs a tree and falls out, then climbs the tree
and falls out again, what is the probability that it lands on its feet

Answers

The probability that the cat lands on its feet both times it falls out of a tree is 0.85

How to determine the probability?

The probability that the cat lands on its feet is given as:

P(Feet) = 0.92

The probability that it lands on its feet twice is calculated using:

P = P(Feet) * P(Feet)

So, we have:

P = 0.92 * 0.92

Evaluate

P = 0.85

Hence, the probability is 0.85

Using separation of variables for the differential equation, it is found that:

b) The solution is: [tex]P(t) = 5000e^{kt}[/tex]

c) In 6 months, the population is: [tex]P(6) = 5000e^{6k}[/tex]

What is the differential equation?

Population of fishes in a pond is directly proportional to amount of fishes present in the bond, hence the differential equation is:

[tex]\frac{dP}{dt} = kP[/tex]

In which k is the growth rate.

What is separation of variables?

In separation of variables, we place all the factors of y on one side of the equation with dy, all the factors of x on the other side with dx, and integrate both sides.

Hence, for the differential equation in this problem:

[tex]\frac{dP}{dt} = kP[/tex]

[tex]\frac{dP}{P} = k dt[/tex]

[tex]\int \frac{dP}{P} = \int k dt[/tex]

[tex]\ln{P} = kt + P(0)[/tex]

[tex]P(t) = P(0)e^{kt}[/tex]

In which P(0) = 5000 is the initial population, hence:

[tex]P(t) = 5000e^{kt}[/tex]

each day in June?
O9.4

O 11
O 15

Answers

The best estimate for the average number of sunlight hours she can expect each day in June is 9.9 hours

To answer the question, we need to know what a regression model is

What is a regression model?

A regression model is an equation or model that shows if there is a relationship between two variables.

Now, given that Yuki uses the regression model y = -2.8sin(0.65x + 120.2) + 12.2 to calculate the average number of sunlight hours per month, where x = 1 represents January.

Since we need to determine the average number of sunlight hours she can expect each day in June. Since June is the sixth month, we substitute x = 6 into the equation.

Average number of sunlight hours in June

So, y = -2.8sin(0.65x + 120.2) + 12.2

y = -2.8sin(0.65(6) + 120.2) + 12.2

y = -2.8sin(3.9 + 120.2) + 12.2

y = -2.8sin(124.1) + 12.2

y = -2.8(0.8281) + 12.2

y = -2.32 + 12.2

y = 9.88

y ≅ 9.9

So, the best estimate for the average number of sunlight hours she can expect each day in June is 9.9 hours
