control group/ first batch

Response variable/ height,texture,and taste

Explanatory variable/ new brand of yeast

The terms with the correct descriptions are;

1. control group/ first batch

2. Response variable/ height,texture,and taste

3. Explanatory variable/ new brand of yeast

An experiment is a technique used to confirm or deny a hypothesis, as well as assess the likelihood or effectiveness of something that has never been tried before. Experiments refers to what happens when a specific factor is modified, which sheds light on cause-and-effect relationships.

We are given that baker is experimenting with a new brand of yeast. He can bakes his first batch of bread using the old brand of yeast that he usually uses and a second batch using the new brand of yeast.

Since baking both batches of bread, he compares the height, texture, and taste of each batch.

The terms with the correct descriptions in the context of this scenario are;

1. control group/ first batch

2. Response variable/ height,texture,and taste

3. Explanatory variable/ new brand of yeast

The equation that represents s, the total number of seventh-grade students at the middle school is given by: Option A: [tex]18 = 0.1s[/tex]

Suppose that the whole thing is of value V.

Then its one-nth part is symbolically written as: [tex]V \times \dfrac{1}{n}[/tex] (V is divided in n equal part, and each part is called one-nth part of V).

For the considered case, we've got the figures as:

Every seventh grade student at considered school takes one language class. It means, if s = Total number of seventh grade student, then:

[tex]\dfrac{s}{7}[/tex]  is the number of students taking language class.

Now, it is said that: One-tenth of the seventh grade students like French, and that they are total 18 in counts.

Writing it symbolically gives:

[tex]\dfrac{s}{10} = 18[/tex]

Since we know that [tex]\dfrac{a}{b} = a \times \dfrac{1}{b}[/tex]

Thus,

[tex]\dfrac{s}{10} = s \times \dfrac{1}{10} = s \times 0.1= 18\\\\0.1 s = 18\\18 = 0.1s[/tex]

(sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)

Thus, the equation that represents s, the total number of seventh-grade students at the middle school is given by: Option A: [tex]18 = 0.1s[/tex]

Answer:

Hope this settles it for ya! XD

Step-by-step explanation:

g'day all!

Answer:

79

Step-by-step explanation:

cuz,
x equals the number of minutes so use the y slope formula

0.10(x)+the intercept = y
0.10(350)+the intercept = 84
35+the intercept = 84
the intercept = 49
so the equation is
0.10(x)+49 = y
or
1/10(x)+49 = y
1/10(300)+49=y
30+49=y
79=y

Answer:

8.4

Step-by-step explanation:

The diagonals of a rectangle are equal.

That means WY = XZ

16x+2 = 36x-6

Subtract 16x from each side.

16x -16x+2 = 36x-16x-6

2 = 20x -6

Add 6 to each side

2+6 = 20x-6+6

8 = 20x

Divide by 20

8/20 = 20x/20

2/5 =x

We want to find the length of the diagonal

WY = 16 ( 2/5) +2

Changing to decimal form

WY =16 * .4 +2

WY =6.4+2

     = 8.4

I did some math and i got this

x = -2

Hello.

In order to solve the equation, we need to isolate x.

First, subtract 1 from both sides:

[tex]\mathrm{7x+1-1=8x+3-1}[/tex]

[tex]\mathrm{7x=8x+2}[/tex]

Now, subtract 8x from both sides:

[tex]\mathrm{7x-8x=8x-8x+2}[/tex]

[tex]\mathrm{7x-8x=2}[/tex]

[tex]\mathrm{-x=2}[/tex]

Now, the minus sign is the same as -1.

In order to isolate x, we need to multiply both sides by -1:

[tex]\mathrm{x=-2}[/tex]

Therefore, the answer is

[tex]\mathrm{x=-2}[/tex]

I hope it helps.

Have a nice day.

Answer:

A - 17.576

Step-by-step explanation:

All we have to do is replace s with 2.6!

V = s^3

v = 2.6^2

v = (2.6)(2.6)(2.6)

v = 6.76 * 2.6

v = 17.576

So, the volume of the cube is 17.576 feet! :)

Answer:

Step-by-step explanation:

This is basically a vocabulary question. Angle pairs around a transversal crossing a pair of parallel lines all have names. Those names are used to refer to different theorems about the relationships of the angles to each other. Once you understand the words being used, the vocabulary is easier to remember.

Angles formed where one line crosses another form a linear pair if they share a side and the non-shared sides are opposite rays. If they share a vertex, but not a side, they are vertical angles. The angles of a linear pair are supplementary: they total 180°. Vertical angles are supplementary to the same angle, so vertical angles are congruent. These relations hold anywhere lines cross.

__

Where a single line crosses two (parallel) lines, that line is called a "transversal". Four angles will be formed at each intersection. Some of those angles are between the (parallel) lines, so are referred to as interior angles. The ones that are not between the (parallel) lines are referred to as exterior angles. The angles are alternate if they are on opposite sides of the transversal, and they are consecutive, or same-side if they are on the same side of the transversal.

Angles that lie in the same direction from the crossing point (to the northeast, for example) are corresponding angles.

__

In your figure, we can identify the following pairs:

The theorems referenced above will tell you if and only if the lines are parallel ...

____

Using the above, we find the answers to your questions to be ...

  1. (a, f) - corresponding angles (b)

  2. (b, h) - alternate interior angles (a)

  3. (h, g) - vertical angles (d)

  4. (c, g) - alternate exterior angles (c)

  5. (a, c) - supplementary angles (e)

  6. (e, i) - corresponding angles (b)

_____

Additional comment

In the above, we put (parallel) in parentheses, because these same definitions apply where the crossed lines may not be parallel. The relevant angle relationships can be used to determine if the lines are parallel or not. For example, if "corresponding" angles are congruent, the lines will be parallel. If "consecutive interior" angles do not total 180°, the lines cannot be parallel.

These same relationships hold in geometric figures, such as rectangles, trapezoids, parallelograms. For example, each side of a parallelogram is a transversal crossing a pair of parallel lines (the adjacent sides). Sometimes, you're asked to prove particular angle relationships in these figures. You can often do so by making use of the angle theorems related to parallel lines.

Answer:

A) see step-by-step

B) (2, 3)

Step-by-step explanation:

Part A

Plot the two linear equations. The point at which they intersect is the solution to the system.

y = 2x - 1

y = 4x - 5

Part B

see attached diagram

To solve algebraically:

equate the equations and solve for x:

⇒ 2x - 1 = 4x - 5

⇒ -2x = -4

⇒ x = 2

Substitute found value for x into one of the equations and solve for y:

⇒ 2(2)- 1 = 3

Therefore, solution is (2, 3)

We will use graphical method

==========================================

Explanation:

The 102 inscribed angle cuts off the arc that's composed of the 140 and 'a'.

Due to the inscribed angle theorem, we know that a+140 is exactly equal to twice that of 102.

This means,

a+140 = 2*102

a+140 = 204

a = 204-140

a = 64

-----------------

The angles 102 and c are inscribed angles opposite one another. They add to 180. This is true for any inscribed quadrilateral.

c+102 = 180

c = 180-102

c = 78

-----------------

Another useful rule is that the four angles of any quadrilateral always add to 360.

102+92+c+d = 360

102+92+78+d = 360

272+d = 360

d = 360-272

d = 88

-----------------

The inscribed angle d cuts off the arc a+b

This means 2d is the measure of a+b because of the inscribed angle theorem.

a+b = 2d

64+b = 2*88

64+b = 176

b = 176-64

b = 112

Answer:

Volume of the filling cabinet = 15ft^3

Step-by-step explanation:

volume = d * b * h

and the filling cabinet is

height = 5ft

width = 18 inch

depth = 2ft

we will first convert the width from inches to feet

where 1 ft -------- 12 inches

          (x) ft ---------18 inches

therefore by cross multiplying

 12 * (X) = 18 * 1

  12 (X) = 18

  X = 18 / 12

  X = 1.5 ft

so Volume = 2 * 1.5 * 5 = 15 cubic feet or 15ft^3
