Answer:

area = 301.44 in²

Step-by-step explanation:

area of top and bottom = π4² = 50.24 each, 100.48 in² for both

circumference = π2r = π2(4) = 25.12

25.12 x 8 = 200.96 in² area of side

100.48 + 200.96 = 301.44 in²

Answer: The margin of error tells that the proportion of the a random sample women said they do not get enough time for themselves can be differ by ±3% than the estimated proportion (47%)

Step-by-step explanation:

Given : A New York Times poll found that 47% of the women said they do not get enough time for themselves.

The poll announced a margin of error of ± 3% for 95% confidence in its conclusions.

A margin of error gives that value of percentage error of in results by which any random value will differ from the real population value.

Here the margin of error tells that the proportion of the a random sample women said they do not get enough time for themselves can be differ by ±3% than the estimated proportion (47%).

Juan and his friends bought drinks for a charity event. The table shows the numbers of each kind of drink bought, and the amount

OverLord2011 [107]

Answer: soda costs $3

Lemonade costs $4

Water costs $2

Step-by-step explanation:

The table shows the number of Soda, lemonade and water bought by Juan, Lee and morris and the total amount each of them spent in buying these drinks

Juan spent $43 on 5 bottles of soda, 4 bottles of lemonade and 6 bottles of water

Lee spent $34 on 2 bottles of soda, 5 bottles of lemonade and 4 bottles of water

Morris spent $41 on 3 bottles of soda, 7 bottles of lemonade and 2 bottles of water

Let price of soda be x

Let price of lemonade be y

Let price of water be z

From the table

5x + 4y + 6z = 43 - - - - - - 1

2x + 5y + 4z = 34 - - - - - - 2

3x + 7y + 2z = 41 - - - - - - -3

Multiply equation 1 by 2 and equation 2 by 5

10x + 8y + 12z = 86

10x + 25y+20z =170

Subtracting

-17y -8z= -84 - - - - - -4

Multiply equation 2 by 3 and equation 3 by 2

6x + 15y+12z = 102

6x + 14y + 4z = 82

Subtracting

y + 8z = 20 - - - - - 5

Add equation 4 and equation 5

-16y = -64

y= -64/-16 = 4

Put y= 4 in equation 4

-17 × 4 -8z = - 84

-68-8z = -84

-8z = -16

z = -16/-8 = 2

Put y = 4 and z = 2 in equation 1

5x + 4×4 + 6×2 = 43

5x + 16 + 12 = 43

5x = 43-28= 15

x = 15/5 = 3

Construct a polynomial function with the stated properties. Reduce all fractions to lowest terms.

drek231 [11]

<h3>Answer:</h3>

g(x) = (11/12)x³ +(11/2)x² +(55/12)x -11

<h3>Step-by-step explanation:</h3>

A polynomial with zero "a" will have (x -a) as a factor. Your 3rd-degree polynomial will have the three factors ...

... f(x) = (x -(-4))·(x -(-3))·(x -1)

This will have a y-intercept of (4·3·(-1)) = -12. In order to move it to -11, we need to vertically scale this function by a factor of 11/12. Then our poynomial is ...

... g(x) = (11/12)(x+4)(x+3)(x-1)

Multiplying this out, you get ...

... g(x) = (11/12)x³ +(11/2)x² +(55/12)x -11
