Answer: Strong negative

Step-by-step explanation:

Correlation coefficient tells about the strength ( Strong , moderate or weak ) and direction ( positive or negative) of the relationship between two quantities.

The given correlation coefficient :-0.898

Since, it lies between -1 and -0.5 and has negative sign, it means it indicates a strong negative  between the two things.

Hence, the correct answer is "strong negative ".

0.0625 is what i got

Step-by-step explanation:

64, -32, 16, --8, 4, -2, 1, -.5, .25, -.125, 0.0625

Answer:

You actually do not ask anything here, so i will find the equation for the height and i will use it to find something useful, like the maximum height of the baseball.

For any object in a vertical motion, the only force acting on it is the gravitational force, so the acceleration of the object will be equal to g.

a(t) = -g

where the minus sign is because the gravitational acceleration pulls down.

For the velocity we can integrate over time, and get:

v(t) = -g*t + v0

Where v0 is the initial velocity, in this case v0 = 72 ft/s

v(t) = -g*t + 72ft/s

with this equation we can find the time in wich the height is maximum, we need to find the time where the velocity is 0.

-g*t + 72 = 0

t = 72/g

for the height we can integrate over time again:

h(t) = (-g/2)*t^2 + 72ft/s*t + h0

where h0 is the initial height, in this case h0 = 3ft

here we can also replace the value of g = 32ft/s^2

h(t) = (-16ft/s^2)*t^2 + 72ft/s*t + 3ft

Now we can evaluate this in the time that we previously find, t = 72/g = 72/32 = 2.25s

h(2.25s) = -16*2.25^2 + 72*2.25 + 3 = 85.08 feet

Answer:

I think it is not proportional because the line is supposed to go thro the middle of each dot, and some of the dots don't have a line thro the middle only on the side or not even on the dot.

The last graph f(x)=x^2-6x-1

Step-by-step explanation:

The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.  

The graph shown in picture D with equation f(x) = x²-6x-1 , has axis of symmetry at x = 3.

4 graphs are given in order to identify which of them contains axis of symmetry at x = 3

The axis of symmetry is the center axis of the curves where the curve is equally divided.

For Picture A
The axis of symmetry is x = 1.5 so it is not the correct option.

For picture B
The axis of symmetry is x = 1.3 so it is not the correct option.

For picture C
The axis of symmetry is  x = -3. So it is not correct option

For picture D
The axis of symmetry is x = 3.  it is the correct option.

The graph shown in picture D with equation f(x) = x²-6x-1 , has axis of symmetry at x = 3.

Final answer:

The minimum amount of paper needed to make the paper cup to the nearest whole cm² is approximately 283 cm².

Explanation:

To find the minimum amount of paper needed to make the paper cup, we need to calculate the surface area of the cup. The formula for the surface area of a cylinder is:

A = 2πrh + π[tex]r^2[/tex]

Given that the height (h) of the cup is 9 cm and the radius (r) of the circular opening is 2.5 cm, we can plug in the values to calculate the surface area:

A = 2 × 3.14159 × 2.5 × 9 + 3.14159 × [tex]2.5^2[/tex]

Simplifying the equation, we get:

A ≈ 282.74 [tex]cm^2[/tex]

Rounding to the nearest whole , the minimum amount of paper needed is approximately 283 [tex]cm^2.[/tex]

Answer:

the answer is (-3,-4)

Step-by-step explanation: -3, -4

The vertex of the parabola is (-3, -4)

A parabola is defined as a set of points in a plane which are equidistant from a straight line or directrix and focus.

Given:

The solid circles along the parabola are:

(-6, 5), (-5, 0), (-4, -3), (-3, -4), (-2, -3), (-1, 0), (0, 5).

As, the minimum point of y occurs at (-3, -4).

So, the x-intercept of the parabola is

x=-5 or x=-1

x+5=0 or x+1=0

(x+5)(x+1)=0

x² + 6x+ 5 =0

Now, vertex of equation at axis of symmetry x= -b/2a

Answer:  5/19

Step-by-step explanation:

There is a  total of 20 tickets numbered from 1 to 20.

10 of the tickets has even number and 10 of the tickets have odd numbers.

probability of drawing a ticket that has even number =10/20 which is equal to 1/2

there are total 19 tickets and 10 odd tickets are available.

Probability of drawing a ticket that has odd number =1019

probability =1/2∗10/19=5/19

Answer:

a. 5/19, b. 14/95

Step-by-step explanation:

a. since the first number drawn has 10/20 chance of being even and it's not put back (you assume that you pull an even #), so the second number pulled has a 10/19 chance of being odd.

10/20*10/19 = 5/19

b. 2, 3, 5, 7, 11, 13, 17, 19 are the prime numbers, so 8/20 for the first pull and then 7/19 for the second pull

8/20*7/19 = 14/95

Final Answer:

The magnitude of the resultant force when two 10 pound forces act on the same object 135° apart is approximately 18.47 pounds.

Explanation:

To find the magnitude of the resultant force when two forces are acting at an angle to each other, we can use the law of cosines. In this scenario, we have two forces each of 10 pounds acting on an object with an angle of 135° between them. Let's denote the forces as F1 and F2, both of which have magnitudes of 10 pounds. The angle between them is θ = 135°.

The formula for the resultant force R when two forces act at an angle θ is:

[tex]\[ R = \sqrt{F1^2 + F2^2 + 2 \cdot F1 \cdot F2 \cdot \cos(θ)} \][/tex]

In our case:

[tex]\[ F1 = F2 = 10 \, \text{pounds} \][/tex]

[tex]\[ θ = 135° \][/tex]

Plugging these values into the formula, we get:

[tex]\[ R = \sqrt{10^2 + 10^2 + 2 \cdot 10 \cdot 10 \cdot \cos(135°)} \][/tex]

[tex]\[ R = \sqrt{100 + 100 + 200 \cdot \cos(135°)} \][/tex]

The cosine of 135° is -√2/2 (since 135° is in the second quadrant where the cosine is negative):

[tex]\[ R = \sqrt{200 - 200 \cdot \frac{-\sqrt{2}}{2}} \][/tex]

[tex]\[ R = \sqrt{200 + 100\sqrt{2}} \][/tex]

[tex]\[ R = \sqrt{200 + 100 \cdot 1.414} \] (Since √2 is approximately 1.414)[/tex]

[tex]\[ R = \sqrt{200 + 141.4} \][/tex]

[tex]\[ R = \sqrt{341.4} \][/tex]

[tex]\[ R \approx 18.47 \text{ pounds} \][/tex]

Therefore, the magnitude of the resultant force when two 10 pound forces act on the same object 135° apart is approximately 18.47 pounds.

Step-by-step explanation:

Two find the final probability asked, first we need to find each probability.

This probability is defined by the sum of the probability of getting a card with S, and a probability of getting a card with E. Remeber, when the probability involves "or", that means sum.

[tex]P_{S \ or \ E} =\frac{1+1}{4}=\frac{2}{4} =\frac{1}{2}[/tex]

There are two tiles only, and one of them is numbered 2. So, its probability is

[tex]P_{2}=\frac{1}{2}[/tex]

There are two discs only. So, the probability of getting a red disc is

[tex]P_{red}=\frac{1}{2}[/tex]

Now, the combined probabilty of all these events can be found by multiplying,  because we want to now the chances of getting all these results which are independent.

[tex]P_{total}=\frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} =\frac{1}{8}[/tex]

Therefore, the probability is 1/8.

Explanation:

To find the value of the house at the end of three years, we need to calculate the appreciation for each year and add it to the original value. Since the value of the house appreciates by 7.5% each year, we can calculate the value after three years using the formula:

New Value = (1 + Rate of Appreciation) * Original Value

Option 3

g(x) = Negative RootIndex 3 StartRoot x + 4 EndRoot; x greater-than-or-equal-to –4

Step-by-step explanation:

Since the graph starts at x = -4 and towards the right, domain is x 》-4

g(x) = -(x + 4)^⅓

Because,

0 = -(-4 + 4)^⅓

0 = 0

The function g(x) for the restricted domain is g(x) = -∛(x-4); x ≥ -4.

The function g(x) for the restricted domain can be determined by analyzing the given information. The function starts at (-4, 0) and curves through the y-axis at (0, 1.5) before passing through point (4, 2). Based on this, the correct function is g(x) = -∛(x-4); x ≥ -4.

Answer:

The required probability is [tex]\dfrac{1}{12}[/tex].

Step-by-step explanation:

Let A be the event of rolling the number cube.

Let B be the event of tossing the coin.

Total number of possibilities of rolling the number cube and tossing the coin are 12 here.

To find the total yards of ribbon, convert the length of each piece of ribbon from feet to yards and multiply it by the total number of pieces. James bought 707 yards of ribbon.

To find the total yards of ribbon, we need to convert the length of each piece of ribbon from feet to yards and then multiply it by the total number of pieces.

Since 1 yard is equal to 3 feet, we can use the conversion factor of 1 yard/3 feet to convert each piece of ribbon from feet to yards.

2.1 feet x (1 yard/3 feet) = 0.7 yards

Now, we can multiply the converted length of each piece of ribbon (0.7 yards) by the total number of pieces (1010) to find the total yards of ribbon:

0.7 yards x 1010 = 707 yards

Therefore, James bought a total of 707 yards of ribbon.
