Answer 1

Answer:

[tex]50.04[/tex]

Step-by-step explanation:

Use this formula for arc length

[tex]2\pi \times r( \frac{x}{360} )[/tex]

where r is the radius and x is the arc measure.

We know Arc de is 8.73 so we are finding x.

R equal 10.

[tex]2\pi \times 10( \frac{x}{360} ) = 8.73[/tex]

[tex]20\pi( \frac{x}{360} ) = 8.73[/tex]

[tex]20\pi \times x = 3142.8[/tex]

[tex]x = \frac{3142.8}{20\pi} [/tex]

x=50.04

Answer 2

The value of the angle will be 50.04.

What will be the angle?

It is given in the question that

The arc of the circle A=8.73 In

The radius of the circle =10 In

Now from the formula of arc

[tex]A=2\pi r(\dfrac{\theta}{360} )[/tex]

[tex]8.73=2\pi 10\times \dfrac{\theta }{360}[/tex]

[tex]\theta = \dfrac{8.73\times 360 }{ 2\pi\times 10} =50.04[/tex]

[tex]\theta=50.04[/tex]

Thus the value of the angle will  be 50.04

A scientist selected a random sample of seven varieties of peach ice cream to investigate the relationship between the density, in pounds per cubic inch, of the varieties of ice cream and the percent concentration of peaches in the ice cream. Assuming all conditions for inference are met, which of the following significance tests should be used to investigate whether there is convincing evidence at the 0.05 level of significance that a greater percent of peaches in the ice cream is associated with an increase in the density of the ice cream?

A. A two-sample t-test for a difference between means

B. A chi-square test of independence

C. A linear regression t-test for slope

D. A two-sample z-test for a difference between proportions

E. A matched pairs t-test for a mean difference

Answers

Answer:

The significance test that would be used to investigate whether there is convincing evidence at 0.05 level of significance that a greater percent of peaches in the ice cream is associated with an increase in the density of the ice cream is option C;

C. A linear regression t-test for slope

Step-by-step explanation:

The linear regression t-test for slope is a test for determining the existence of a statistically significant linear relationship between two variables, a independent variable, X and an dependent variable Y in the following form;

Y = B₀ + B₁·X

The test is used to test the regression line slope where we have;

B₀ = The constant

B₁ = The slope also known as the regression coefficient

The given information tested in the question is if an increase in the peaches in the ice cream is associated with an increase in the density of the ice cream, therefore, the test to investigate the relationship between the rate of both variables is the linear regression t-test for slope.

Therefore, we have

Y = B₀ + B₁·X

Where;

X = The percentage of peaches in the ice cream

Y = The density of the ice cream

Answer:

x = 13.77

Step-by-step explanation:

cos 37° = 11/x

0.7986 = 11/x

0.7986x = 11

x = 11/0.7986

x = 13.77

The value of the hypotenuse x will be 14.37.

What will be the value of the hypotenuse?

Here in the triangle, it is given that

The angle between base and hypotenuse = [tex]37^0[/tex]

The base =11

So from the property

[tex]COS\theta=\dfrac{Base}{Hypotenuse}[/tex]

[tex]Cos37=\dfrac{11}{x}[/tex]

[tex]x=\dfrac{11}{0.7654}[/tex]

[tex]x=14.37[/tex]

Thus the value of the hypotenuse x will be 14.37.

1. The midsegment of a trapezoid is half the sum of the bases.
true or false ?

Answers

Answer:

TRUE

Step-by-step explanation:

TRUE

Therefore, the given statement "The midsegment of a trapezoid is half the sum of the bases" is True.

What is a trapezium?

A trapezium is a quadrilateral with two parallel sides. It has two non-parallel sides that are called the legs of the trapezium, and the other two sides are called the bases.

The midsegment of a trapezoid is a line segment that connects the midpoints of the two non-parallel sides of the trapezoid. Since the midsegment connects the midpoints of the two non-parallel sides, it will always have the same length as half the sum of the two bases.

Therefore, the given statement is True.

The sum of David's weight and Mike's weight is 180 pounds. If you subtract David's weight from Mike's weight, you get half of Mike's weight. How much does Mike weigh?

Answers

Answer: 120 Pounds

Step-by-step explanation:

Given

The Sum of David and mike weight is 180 pounds

Suppose the weight of David is x and the weight of mike is y

So, [tex]x+y=180[/tex]

Also, subtracting David's weight from Mike's weight, we get half of Mike's weight

[tex]\Rightarrow y-x=\dfrac{y}{2}\\\Rightarrow 2x=y[/tex]

Put the value of x in the above equation, we get

[tex]\Rightarrow 1.5y=180\\\Rightarrow y=120\ pounds[/tex]

Thus, mike Weighs 120 Pounds

A polynomial of degree 3 is multiplied by a polynomial with of degree 5

What is the degree of the product?

A. 2
B.8
C.15
D. The degree could vary based on the polynomials

Answers

Answer:

B.8

Step-by-step explanation:

The degree of a polynomial refers to the term with the highest exponent.  Thus the highest exponent in a degree 3 polynomial is x3; for a degree 5 polynomial, it's x5.  When you multiply

x3*x5 = x3+5 = x8.  

So the product of a degree 3 polynomial and a degree 5 polynomial is a degree 8 polynomial.

Your leading term will result from the 3-degree term of the first polynomial, and the 5-degree term of the second.  So you'll have something like ax3 * bx5.  That will result in x3*x5=x8, so your product will have degree 8.

Answers

Answer:  A. inverse variation; xy = 20

ANSWER

Step-by-step explanation:  Brainly

B) xy=20

Inverse because it is of the form y=k/x, intuitively you can see that as x increases y decreases, hence "inverse variation".

...............................................................................................................................................

Answer:

Option B is correct

Inverse variation , xy = 20

Step-by-step explanation:

Inverse variation states:

If  

then the equation is in the form of:

or

xy = k            ....[1]

As per the statement:

Given the data:

x : 2 4 8 12

y : 10 5 5/2 5/3

Let any value of x and y to find k:

x = 4 and y = 5

Substitute in [1] we have;

⇒20 = k

or

k = 20

then we get;

xy = 20

Check:

Substitute x = 12  and y = 5/3

⇒ true.

Therefore, the the data in the table represent a inverse variation and an equation to model the data in the table is, xy = 20

If AC = 9 cm and tan ABC = 0.75, what is the length of BC?

Answers

Answer:

12 cm confirm ...................

From the concept of trigonometric ratios, we determine the length of the side  BC is 6.75 cm.

What are trigonometric ratios in terms of a right-angle triangle?

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, The length of the side AC = 9cm.

The measure of tan∠ABC = 0.75.

We know tan = opposite/adjacent.

Here, the opposite is AC and adjacent is BC.

Therefore, 0.75 = 9/BC.

BC = 9×0.75.

BC = 6.75.
