Answer:

[tex]\frac{3}{8}[/tex]

Step-by-step explanation:

There are a list of possible outcomes:

This represents 8 outcomes.

The only ones that have two tails are:

Because there are 3, this means that the probability in a fraction form of Brian getting exactly 2 tails is 3/8. P ( exactly 2 tails) = 3/8.

The solution to the equation 4 + √(5x + 66) = x + 10 is x = -10 and x = 3

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

4 + √(5x + 66) = x + 10

Subtract 4 from both sides

So, we have

√(5x + 66) = x + 6

Take the square of both sides

5x + 66 = x² + 12x + 36

So, we have

x² + 7x - 30 = 0

When expanded, we have

x² + 10x - 3x - 30 = 0

So, we have

(x + 10)(x - 3) = 0

Solve for x

x = -10 and x = 3

Hence, the solution to the equation 4 + √(5x + 66) = x + 10 is x = -10 and x = 3

In which:

In this problem, we have that the parameters are given as follows:

P = 80000, r = 0.06, n = 25 x 12 = 300.

Hence:

r/12 = 0.06/12 = 0.005.

Step-by-step explanation:

2 yards and 4 inches

Each yard has 3 feet.  Each foot has 12 inches.  The total inches in 3 yards is therefore:

(2 yards)*(3 feet/yard)*(12 inches/Foot) = 72 inches  [Note how the units cancel to leave only inches]

This means we have a total of 72 + 4 inches = 76 inches total

19 Inches

Compared to 19 inches, 72 inches is almost 3.79 times longer.

The correct answer is option D which is the second coordinate of the vertex of the quadratic function that represents the maximum height of the baseball.

The polynomial having a degree of two or the maximum power of the variable in a polynomial will be 2 is defined as the quadratic equation and it will cut two intercepts on the graph at the x-axis.

The second coordinate of the vertex of the quadratic function represents the maximum height of the ball.

The height of a baseball hit from a bat is modeled by a quadratic function of time, h(t)

General form of h(t) will be -16x² + v(t) + h

Where v represents initial velocity and h represents the initial height

h(t) represents the height of the baseball

h(t) is negative so the height reaches the maximum

vertex (h,k) represents maximum height (k) when time t=h

So the second coordinate of the vertex of the quadratic function represents the maximum height of the ball.

The distance between the refreshment stands is 440 feet

From the question, we are to determine how far apart are the refreshment stands in feet

From the given information,

The parade route is 3/4 mile long

and

There are refreshment stands at the beginning and end of the route. And there will also be 8 refreshment stands along the route.

This means there will be 10 refreshment stands in all.

If there are 10 refreshment stands in all, then there will be 9 spaces between the refreshment stands.

∴ The distance between any two refreshment stands will be

3/4 mile ÷ 9 = 3/36 mile = 1/12 mile

Now, we will convert this to feet

NOTE: 1 mile = 5280 feet

∴ 1/12 mile = 1/12 × 5280 feet

= 440 feet

Hence, the distance between the refreshment stands is 440 feet.

Answer:

x = 97.5 degrees

Step-by-step explanation:

First, we need to know what the total sum of interior angles. We use the formula (n-2) * 180, n being the number of sides.

Since this is a 6-sided polygon, the sum is (6-2) * 180, or 720 degrees.
We have the total sum of interior angles, so now we have all the information we need.
720 degrees = (2x-50) + (x+40) + 80 + (x+20) + 90(right angle symbol) + 150
720 = 4x + 330 (subtract 330 from both sides)

390 = 4x (divide by 4)
x = 97.5 degrees

The Sine or Sin(θ) in a right angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,

Sin(θ) = Perpendicular/Hypotenuse

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The hypotenuse is the longest side of the triangle.

The height of the wall can be found by using the trigonometry ratios, therefore, the height of the wall can be determined as,

Sin(74°) = (Height on the wall)/(Length of the wall)

Sin(74°) = (Height on the wall)/22 ft

(Height on the wall) = 21.148 ft

We are told that the equation that describes the curve of best fit for the fish population (y) is;

y = 1500(0.9)^(z)

where z represent the

number of 10-year intervals since 1960.

The table started in the year 1960 and we want to find the population in the year 2020.
Number of years after 2020 is;
