Step-by-step explanation:

Took the test and got it right

Answer:

Part (a)

It depends how your calculator calculates quadratic regressions.

For my calculator:

a = 1.177142857 = 1.18 (nearest hundredth)

b = 42.22257143 = 42.22 (nearest hundredth)

c = -12.87142857 = -12.87 (nearest hundredth)

⇒ y = 1.18 + 42.22x - 12.87x²

Therefore, the quadratic regression equation in standard form is:

[tex]y = -12.87x^2+ 42.22x + 1.18[/tex]

Part (b)

To estimate the height of the rocket after 5 seconds, input x = 5 into the regression equation:

[tex]\implies -12.87(5)^2+ 42.22(5) + 1.18=-109.47[/tex]

As this gives us a negative value, this means that the rocket would have come back to the ground before 5 s.  Therefore, the height of the rocket at 5 s will be 0 ft.

(see attached graph → the rocket will hit the ground at approx 3.3 s)

Answer:

Question B is (12,-7)

Step-by-step explanation:

The 2nd question is asking for the preimage. You did what the image would be if (4,-3) was the preimage.

An equation is formed of two equal expressions. The quadratic equation that can be used to find x, the smaller number is x²+x-272.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the first number be x.

Now since the two numbers are consecutive numbers the other number will be (x+1). Also, it is mentioned in the problem that the product of the two numbers is 272. Therefore, the equation that can represent the product will be,

[tex]x \times (x+1) = 272\\\\x^2 + x =272\\\\x^2 + x -272 = 0[/tex]

Thus, the quadratic equation that can be used to find x, the smaller number is x²+x-272.

Answer:

3/50.

Step-by-step explanation:

There are 10 marbles in the bag.

Probability( a green marble) =  2/10 = 1/5.

Now we replace the green marble in the bag so it contains 10 marbles again.

Probabilty(a yellow marble) = 3/10.

So Probability(Choosing a green then a red with repeacemen)

= 1/5 * 3/10

= 3/50.

Answer:

A    Y= 5x-9

Step-by-step explanation:

Answer:

I think a possible equation can be; f(n) = 4(2)ⁿ

f(n) = a * bˣ

Where;

f(n) = the function of f for every n value

a = Initial value (in this case it would be 4)

b = Rate of change (in this case it would be 2, since the bacteria doubles)

x = exponent (in this case it would be n)

So our final equation would be:

f(n) = 4(2)ⁿ

We know that,

[tex]{\longrightarrow \pmb{\mathbb {\qquad (UV) {}^{2} + (UW) {}^{2} =( VW) {}^{2} }}} \\ \\ [/tex]

Now, we will substitute the given values in the formula :

[tex]{\longrightarrow \pmb{\sf {\qquad (6) {}^{2} + (UW) {}^{2} =( 9) {}^{2} }}} \\ \\ [/tex]

We know that, (6)² = 36 and (9)² = 81. So,

[tex]{\longrightarrow \pmb{\sf {\qquad 36 + (UW) {}^{2} =81}}} \\ \\ [/tex]

Now, transposing 36 to the other side we get :

[tex]{\longrightarrow \pmb{\sf {\qquad (UW) {}^{2} =81 - 36 }}} \\ [/tex]

[tex]{\longrightarrow \pmb{\sf {\qquad (UW) {}^{2} = 45}}} \\ \\ [/tex]

Now, we'll take the square root of both sides to remove the square from UW :

[tex]{\longrightarrow \pmb{\sf {\qquad \sqrt{(UW) {}^{2}} = \sqrt{ 45}}}} \\ \\ [/tex]

When we take the square root of (UW)² , it becomes UW,

[tex]{\longrightarrow \pmb{\sf {\qquad UW = \sqrt{45}}}} \\ \\ [/tex]

We know that, square root of 45 is 6.708.

[tex]{\longrightarrow \pmb{\sf {\qquad UW \approx6.708}}} \\ \\ [/tex]

A group of students formed a circle during a game. The circumference of the circle was about 50.24 feet, and the diameter of the circle was 16 feet. The required expression for value of π is: 3.14

A circle is a form made up of all points on a plane that are at a specific distance from the centre point. In other words, it is the path a moving point in a plane takes to travel around a curve while maintaining a constant distance from another point.

Given that,

The circumference of the circle was about 50.24 feet,

And the diameter of the circle was 16 feet

We have to determine,

Which expression best represents the value of π.

According to the question,

Circumference of the circle = 50.24 feet

Diameter f the circle = 16 feet

Then,

Circumference of the circle = π × d

Circumference of the circle = 50.24 feet

Therefore,

50.24 = π × d

or. π × 16 = 50.24

or,  π = 3.14

Hence, The required expression for value of π is: 3.14

Using the t-distribution, it is found that the value of the test statistic is given by:

(c) -2. 22

At the null hypotheses, it is tested if the mean is not greater than 250, that is:

[tex]H_0: \mu \leq 250[/tex]

At the alternative hypotheses, it is tested if it is greater, that is:

[tex]H_1: \mu > 250[/tex]

It is given by:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

The parameters are:

In this problem, the values of the parameters are:

[tex]\overline{x} = 230, \mu = 250, s = 36, n = 16[/tex].

Hence, the test statistic is given by:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{230 - 250}{\frac{36}{\sqrt{16}}}[/tex]

t = -2.22.

Answer:

6 cm²

Step-by-step explanation:

Since 3 side lengths are given, I assume that this figure is a triangle. The area of a triangle can be determined by using hero's formula.

[tex]\text{Area of triangle} = \sqrt{\text{s(s - a)(s - b)(s - c)}[/tex]

⇒ s = Perimeter/2

⇒ a, b, and c = side lenths of triangle

Replacing a, b, and c as the given side lengths:

[tex]\implies \text{Area of triangle} = \sqrt{\text{s(s - 5)(s - 3)(s - 4)}[/tex]

Determining the perimeter of the triangle:

[tex]\text{Perimeter of triangle = Sum of it's side lengths}[/tex]

[tex]\implies \text{Perimeter of triangle =}\ 5 + 4 + 3[/tex]

[tex]\implies \text{Perimeter of triangle =}\ 12 \ \text{cm}[/tex]

Determining the half of perimeter:

[tex]\text{Half of perimeter} = s = \dfrac{\text{Perimeter}}{2}[/tex]

[tex]\implies s = \dfrac{12}{2}[/tex]

[tex]\implies s = 6[/tex]

Replacing the value of "s" in the formula:

[tex]\implies \text{Area of triangle} = \sqrt{\text{6(6 - 5)(6 - 3)(6 - 4)}[/tex]

Evaluating the area:

[tex]\implies \text{Area of triangle} = \sqrt{\text{6(6 - 5)(6 - 3)(6 - 4)}[/tex]

[tex]\implies \text{Area of triangle} = \sqrt{\text{6(1)(3)(2)}[/tex]

[tex]\implies \text{Area of triangle} = \sqrt{\text{6(6)}[/tex]

[tex]\implies \text{Area of triangle} = 6 \ \text{cm}^{2}[/tex]
