What is the statistical decision regarding the differences between the observed and expected frequencies if the critical value of chi-square is 9.488 and the computed value is 6.079

The correct answer is B. Every year, we bought a homemade apple pie that cost only $5 at a little store on the road to the cabin.

Explanation:

In the sentences presented the section "that cost only $5" is a modifier because this describes the noun "homemade apple pie". Moreover, this modifier should be placed right after the noun it describes to clarify the "$5" refer to the cost of the pie.

This occurs in option B "a homemade apple pie that cost only $5" because this places the modifier after the noun, and this makes the sentence to be clear. On the other hand, in other options the meaning is confusing. For example in A "a homemade apple pie at a little store that cost only $5," it is not clear if the cost refers to the apple or the store.

Answer:

1. 30°

2. [tex]1:1:\sqrt{2}[/tex]

3. 20cm

4. 5cm

Step-by-step explanation:

for the first one:

we have the triangle RVT and we know that

[tex]\angle V = 90\\\\\angle R = 60[/tex]

so [tex]\angle T[/tex] [tex]+ \angle V+\angle R[/tex] = 180

so

[tex]\angle T = 30[/tex]

for the second one

we know by specials right triangles that the sides are

[tex]x:x:x\sqrt{2}[/tex]

divide by x and get

[tex]1:1:\sqrt{2}[/tex]

for the third one

again by 30-60-90 triangle we know that

[tex]2BC=AB\\\\2(10)=AB\\\\AB=20[/tex]

for the fourth one

here we can use excersie 3 and the ratio of XY:YC = 1:1

that means they are equal so

XY=YC

XY = 5

Answer:

x = 9.25

Step-by-step explanation:

It is given that ABC is an isosceles triangle.

m∠A = 43° and m∠C = (6x+13)°

We need to find the value of x.

The sum of a triangle is equal to 180°.

∠A is the vertex angle. For a triangle sum of angle of triangle is equal to 180°

∠A+∠B +∠C=180

43+∠B+(6x+13)°=180

6x+∠B+56=180

6x+∠B = 124

∠B =124-6x

For an isosceles triangle,

∠B = ∠C

124-6x = (6x+13)

124-13 = 6x+6x

111 = 12x

x = 9.25

So, the value of x is 9.25.

Plug the formula into Desmos and even just visually

C.  " y = -6x - 8

is the answer

The equation of the line tangent to the function f(x) = 1 – x² at x = –3 will be y = –6x – 8. Option C is correct.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, the function is,f(x) = 1 – x²

We have to find the equation of the line tangent to the function f(x) = 1 – x² at x = –3.

Determine the function's first derivative f(x), To get the slope at a given location, plug the specified point's x value into f'(x). To determine the tangent point's y coordinate, plug the value of x into f(x). The point-slope formula may be used to combine the slope from step 2 with the point from step 3 to produce the equation for the tangent line.

Thus, the equation of the line tangent to the function f(x) = 1 – x² at x = –3 will be y = –6x – 8.Option C is correct.

The gradient of the line segment between points (1, 2) and (3, -8) will be -5.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

The points are given below.

(1, 2) and (3, -8)

Then the gradient of the line segment will be given as,

m = (- 8 - 2) / (3 - 1)

m = - 10 / 2

m = - 5

The gradient of the line segment between points (1, 2) and (3, -8) will be -5.

Answer:

Number of small boxes purchased : 2

Number of large boxes purchased : 5

Step-by-step explanation:

Let,

x be the number of small boxes of nails purchased

y be the number of large boxes of nails bought

Then according to given statement;

50x+350y = 2550     Eqn 1

y = x+5        Eqn 2

Putting value of y from Eqn 2 in Eqn 1

50x + 350(x+5) = 2550

50x + 350x + 1750 = 2550

400x = 2550-1750

400x = 800

Dividing both sides by 400

[tex]\frac{400x}{400}=\frac{800}{400}\\x=2[/tex]

Putting x=2 in Eqn 2

y = 2+5

y = 7

Hence,

Number of small boxes purchased : 2

Number of large boxes purchased : 5

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

We are given the two functions:

[tex]\displaystyle f(x) \text{ and } g(x)=\sin^{-1}(f(x))[/tex]

And we want to find the ratio that represents:

[tex]\displaystyle \frac{f^\prime(x)}{g^\prime(x)}[/tex]

To do so, we will compute the derivatives of both functions.

For f,  we can simply write that:

[tex]f^\prime(x)=f^\prime(x)[/tex]

For g, we will use the chain rule:

[tex]\displaystyle (u(v(x))^\prime=u^\prime(v(x))\cdot v'(x)[/tex]

We can let:

[tex]u(x)=\sin^{-1}(x)\text{ and } v(x)=f(x)[/tex]

We can double check this by doing the composition:

[tex]g(x)=u(v(x))=\sin^{-1}(f(x))[/tex]

Therefore, by the chain rule, we acquire that:

[tex]\displaystyle g^\prime(x)=\frac{1}{\sqrt{1-(v(x))^2}}\cdot v'(x)[/tex]

By substitution:

[tex]\displaystyle g^\prime(x)=\frac{f^\prime(x)}{\sqrt{1-(f(x))^2}}[/tex]

Hence, our ratio is:

[tex]\displaystyle \frac{f^\prime(x)}{g^\prime(x)}=\frac{f^\prime(x)}{\dfrac{f^\prime(x)}{\sqrt{1-(f(x))^2}}}[/tex]

Simplify:

[tex]\displaystyle \frac{f^\prime(x)}{g^\prime(x)}=\sqrt{1-(f(x))^2}[/tex]

Hence, our answer is C

Answer:

20 miles

Step-by-step explanation:

Given the equation of the line of the graph, y = 8x, where,

y = distance the hurricane travelled in miles

x = time of travel in hours

8 = slope/speed in miles/hour

To find how far the hurricane travelled in 2.5 hours, substitute x = 2.5 into y = 8x

This:

y = 8(2.5)

y = 20 miles

Thus, from the graph, we can estimate this also. On the x-axis, between 2 and 3, we have 2.5 hours. The corresponding value of x = 2.5 is y = 20.

Answer: It means depression

Step-by-step explanation:

Answer:

Being sad means your body has entered a mini-clinical state, bringing back grief and usually making you remember past traumas for no existential reason. Sadness can drive you to feeling alone - not isolated, but alone with your inner thoughts. Your interior feeling cold, and like no one is there to put their hand out and help you become warm again. Sadness can drive you to loneliness, and loneliness can lead you to depression. Depression inverts your brain waves and makes you feel useless, no-good, nothing useful, just a joke.
