Answer:

y = - 9.1768x2 + 122.2567x + 14.9091

Step-by-step explanation:

Given the following :

Month (x) Daily Rental Price (y) 1 $154 2 $205 3 $266 4 $358 5 $403 6 $425 7 $437 8 $430 9 $381 10 $285 11 $211 12 $195

Using the online regression equation graphing tool ; The quadratic model obtained in the form,

y = Ax^2 + Bx + C is :

y = - 9.1768x2 + 122.2567x + 14.9091

Attached below is a picture of the quadratic regression curve.

Answer:

If the population has increased by 12% then to ensure a generated maximum capacity must be more than 12% we already have a figure being 100% prior so the answer is 12% population increase =112% and 12%.of 112 =13.44

We add this to 12

12+13.44= 25.44

What is the median of this set of data: 593, 588, 540, 434, 420, 398, 390, 375
Aleks04 [339]

<u>Answer:</u>

<u><em>426</em></u>

<u />

<u>Explanation:</u>

To find the median number in a set of data start by reordering the data from least to greatest.

<em>original data set:</em>

<em>593, 588, 540, 434, 420, 398, 390, 375</em>

<em />

<em>data set from least to greatest:</em>

<em>375, 390, 398, 420, 434, 540, 588, 593</em>

<em />

Next, you would usually just have to find the middle number in the data set and that would be your median. However, this data set has no one number that is directly in the middle. So, we will add both middle numbers together and then divide our answer by two.

<em>375, 390, 398, </em><em>420, 434</em><em>, 540, 588, 593</em>

<em />

<em>420 + 434 = 854</em>

<em />

<em>854 ÷ 2 = 426</em>

<em />

Therefore, the median of the given data set is <em><u>426.</u></em>

Write an expression for the eighth partial sum of the series using summation notation
balandron [24]

Answer:

option B

Step-by-step explanation:

9/10 + 6/5 + 3/2...........

We find the difference between the terms

\frac{6}{5} - \frac{9}{10}

\frac{12}{10} - \frac{9}{10} = \frac{3}{10}

We will get the same difference when we subtract consecutive terms.

so , d= 3/10, a= 9/10

we find the formula for nth term

a_n = a+(n-1) d

a_n = \frac{9}{10} + (n-1)\frac{3}{10}

a_n = \frac{9}{10} +\frac{3}{10}n-\frac{3}{10}

a_n = \frac{6}{10} +\frac{3}{10}n

a_n = \frac{3}{5} +\frac{3}{10}n

we need to find eighth partial sum so we  take n=1 to 8

sum of 8 terms (\frac{3}{5} +\frac{3}{10}n)

So option B is correct

10% of what number is 78?
Zepler [3.9K]

Answer: x = 780

Step-by-step explanation: Well <u><em>percent</em></u> means <em>over 100</em> so we can set up an equation for this problem by reading it from left to right.

So we know that <u><em>10%</em></u> means <em>10/100</em>, <u><em>of</em></u> means times, <em><u>what</u></em> <em><u>number</u></em> means <em>x</em>, <u><em>is</em></u> means <em>equals</em>, and <em><u>12</u></em> means 12.

Notice that <em>10/100</em> can be reduced to 1/10.

So rewriting our problem we have <em>X/10 = 78</em>.

To get rid of the fraction, we multiply both sides of the equation by 10 and we have <em>x = 780</em>. So, 10% of 780 is 78.

Now let's check our answer back in the original problem to see if it makes sense.

We have <em>10% of 780 is 78</em>. Well we know that 100% of of 780 would be 780 so 10% of 780 should be alot less than 780 so 78 seems to make sense.

The edges of a cube are 5 cm each and the diaganol of a face is approximately 7 cm what is the approximate area of the cross sec
xxTIMURxx [149]

Answer:

The approximate area is 35 square centimeters

Step-by-step explanation:

we know that

The cross section passing through the diagonal of opposite faces of the cube is a rectangle

so

the approximate area is equal to

A=bh

where

b is the diagonal of a face

h is the length side of the cube

we have

b=7\ cm\\h=5\ cm

substitute

A=7(5)=35\ cm^2
