The measure of variation for a numerical data set describes how the values of a number vary with the single number. This measurement shows the difference in the properties of a certain number to the rest of the numbers in the numerical data set.

A linear function models the height of a burning candle. Candle A comes out of the mold at 211 mm and is expected to be at 187

DerKrebs [107]

Answer:

(11.4 - 22.8) / (26 - 7)

-11.4 / 19 this is the rate at which it burns - the slope

h = (-11.4/19)t + b

22.8 = (-11.4/19)7 + b

22.8 = (-79.8/19) + b

22.8 = -4.2 + b

27 = b

h = (-11.4/19)t + 27

Substitute 15 for t to determine the height of the candle.

Figure A is a scale image of Figure B. What is the value of x?

kari74 [83]

Hey there! :)

Answer:

x = 21 units.

Step-by-step explanation:

Since we know Figure A is just Figure B scaled, we can set up a proportion:

$\frac{45}{35}= \frac{27}{x}$

Cross multiply to solve for x:

45 · x = 35 · 27

45x = 945

Divide both sides by 45:

x = 21 units.

Please help it's for a test!

Tanya [424]

Answer:

0.2322 or 23.22 %

Step-by-step explanation:

We have to solve and find the area out of these limits

μ + 0,3 = 210 + 0,3 ⇒ 210,3 and

μ - 0,3 = 210 - 0,3 ⇒ 209.7

z(l) = ( x - 210 ) / (2.8/√84) ⇒ z(l) = - (0.3 * 9,17)/ 2.8

z (l) = - 1.195

We need to interpole from z table

1.19 ⇒ 0.1170

1.20 ⇒ 0.1151

Δ ⇒ 0.01 ⇒ 0.0019

And between our point 1,195 and 1,19 the difference is 0.005

then 0.01 ⇒ 0.0019

0.005 ⇒ ?? (x)

we find x = 0.00095

to get the area for poin z (l) - 1.195 up to final left tail is from z table

0,1170 - 0.00095 = 0.1161

And by symmetry to the right is the same

So 0.1161 * 2 = 0.2322

We find the area out of the above indicated limits the area we were looking for. This is the probability of finding shafts over and below the population mean and 0.3 inches

The simplification form of the expression is 3x²/2 + 2x or three-halves x squared + 2 x option second is correct.

<h3>What is the area of the rectangle?</h3>

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

We have:

A community garden with raised beds is being redesigned. The area of the new rectangular beds can be expressed as one-half x (3 x + 4).

The expression:

$\rm = \dfrac{1}{2}(3x+4)$

By using the distributive property:

$\rm = \dfrac{1}{2}\times3x^2+\dfrac{1}{2}\times4x$

$\rm = \dfrac{3}{2}x^2+2x$

Thus, the simplification form of the expression is 3x²/2 + 2x or three-halves x squared + 2 x option second is correct.
