Answer:

Number 1

Step-by-step explanation:

I can answer the first one! The dependent variable is the measurement. The days in the independent and always the X variable

Answer:

Step-by-step explanation:

The measurement of the plant height. That (presumably) is dependent on the amount of fertilizer. Everything else is held constant (such amount of water, amount of sunlight, even distance from a window (constant heat), is held the same for all plants.

Answer:

  f, h, g

Step-by-step explanation:

You can look at the slope of the tangent lines to the graphs at any given x-value. At x=5, we see that g(x) is the flattest curve and f(x) is the steepest.

In order from greatest to least growth rate, the functions are ...

  f(x), h(x), g(x)

Answer:

[tex]W = 5h - 90 \\ 5h = W + 90 \\ h = \frac{W + 90}{5} [/tex]

Answer:

h = w+90/ 5

Step-by-step explanation:

5h-90=w

5h/5= w+90/5

h= w+90/5

Answer:

P= 6w - 10

P= 2(L+W)

L= 2w-5

P= 2(2w -5+w)

P=2(3w-5)

P= 6w - 10

First bottle's unit cost = 27 cents per oz

Second bottle's unit cost = 27 cents per oz

Both have the same unit cost.

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

Work Shown:

unit cost = price/(number of ounces)

1st bottle unit cost = (1.35)/(5) = 0.27 dollars per oz = 27 cents per oz

2nd bottle unit cost = (2.16)/(8) = 0.27 dollars per oz = 27 cents per oz

Both lead to the same unit cost. Therefore, you can pick either option and it doesn't matter.

Answer:

C) 2

Step-by-step explanation:

From the point (2,0), the next point on the graph is up 2, right 1, meaning that the slope is a positive 2.

[tex]12a^3d^2-6ad^3[/tex]

To factor an integer, we need to divide it by the ascending sequence of primes 2, 3, 5

In the end, the number of times each prime divides the original integer becomes its exponent.

Prime number 2  to the power of 2 equals 4 .

Prime number 3 to the power of 1 equals 3 .

Answer:

70kg- weight of the bag of beans, 90 kg- weight of the bag of salt

Step-by-step explanation:

Suppose the mass of a bag of beans - x kg, the mass of a bag of salt - y kg

The mass 2 bags of beans 2x, The mass 3 bags of salt 3y

2x+3y= 410

The mass of 3 bags of beans 3x, for 2 bags of salt it is 2y

3x+2y=390

We have system of equations (the equations are simultaneous)

2x+3y=410

3x+2y=390

2x= 410-3y

x=205-1.5y

3* (205-1.5y)+2y=390

615-4.5y+2y=390

2.5y= 225

y=90- the mass of the bag of salt

x= 205 - 1.5*90= 205-135= 70- the mass of the bags of beans

Step-by-step explanation:

Answer:

40

Step-by-step explanation:

2x² - 5y + 7 when x = 2 and y = -5

2(2)² - 5(-5) + 7

= 2(4) -5(-5) + 7

= 8 + 25 + 7

= 40

Answer:

  990 square inches

Step-by-step explanation:

The area is the half the product of length and height.

  A = (1/2)(18 in)(110 in) = 990 in²

Since X₁ and X₂ are independent, we have

Var[X₂ - 3X₁] = Var[X₂] + (-3)² Var[X₁]

Var[X₂ - 3X₁] = 8 + 9 × 1

Var[X₂ - 3X₁] = 17

Then the standard deviation of X₂ - 3X₁ is the square root of the variance, √17.

Answer:

  A. False

  B. False

  C. True

  D. True

  E. False

Step-by-step explanation:

A. False -- any triangle has at least two acute angles, whether it is acute, right, or obtuse.

B. False -- by definition, any polygon that is not convex is concave.

C. True -- the angle sum is the same regardless of whether the pentagon is convex or concave. (Provided it is a "simple" polygon, with no crossing sides.)

D. True -- the measure of the interior angle of a regular polygon increases as the number of sides increases. (see E)

E. False -- the exterior angles of a regular polygon are 360° divided by the number of sides. As the number of sides increases, the measure of each exterior angle decreases. (Interior angles are the supplement of exterior angles, so they increase as the number of sides increases.)

Answer:

Region C

Step-by-step explanation:

y ≤ ¼ x + 3 maps the areas C and D including the common boundary line

y ≥ -x + 5 maps the areas B and C including the common boundary line

The common area mapped is C plus its boundaries

Option A is the correct answer

Answer:

sorry for doesn't know the answer

Hi there!  

»»————-　★　————-««

I believe your answer is:  

330

»»————-　★　————-««  

Here’s why:  

⸻⸻⸻⸻

We are rounding the number 326 to the nearest tens.

The '2' is in the tens place, and the '6' is to the right of the digit.

Since the '6' is greater than or equal to 5, then we would round up.

326 ≈ 330

Hope this helps you. I apologize if it’s incorrect.  

Option 1 - StartFraction n Over 2 EndFraction minus 6 + 10; when n = 8, the value is 8.

Step-by-step explanation:

Given : Expression "six less than the quotient of a number and two, increased by ten".

To find : What is the expression and value of expression when n = 8?

Solution :

Let the number be 'n'.

The quotient of a number and two i.e. \frac{n}{2}2n

Six less than the quotient of a number and two i.e. \frac{n}{2}-62n−6

Six less than the quotient of a number and two, increased by ten i.e. \frac{n}{2}-6+102n−6+10

The required expression is \frac{n}{2}-6+102n−6+10 .

Now, when n=8,

\frac{n}{2}-6+10=\frac{8}{2}-6+102n−6+10=28−6+10

\frac{n}{2}-6+10=4-6+102n−6+10=4−6+10

\frac{n}{2}-6+10=82n−6+10=8

The value of the expression is 8.

Therefore, option 1 is correct.

StartFraction n Over 2 EndFraction minus 6 + 10; when n = 8, the value is 8.

Although you said the variance is 120, I suspect you meant to say standard deviation. If that's the case, then

P(970 < x < 1320)

= P((970 - 1250)/120 < (x - 1250)/120 < (1320 - 1250)/120)

≈ P(-2.3333 < z < 0.5833)

= P(z < 0.5833) - P(z < -2.3333)

≈ 0.72012 - 0.009815

≈ 0.7104

If you really did mean variance, then

P(970 < x < 1320)

= P((970 - 1250)/√120 < (x - 1250)/√120 < (1320 - 1250)/√120)

≈ P(-25.5604 < z < 6.3901)

= P(z < 6.3901) - P(z < -25.5604)

≈ 1 - 0

≈ 1

Answer:

8, 10, 4, 7

Step-by-step explanation:

Missing side = x

Rules for x:

It should be less than the sum of the other two sides

It should be greater than the difference of the other two sides

8 + 10 = 18

10 - 8 = 2

2<x<18

8, 10, 4, 7
