(3a-6b+12)-(6a-2b+7)

Natasha2012 [34]

Answer:

-3a-4b+5

Step-by-step explanation:

we distribute the minus sign

-(6a-2b+7

-6a+2b-7

And now combine like terms

3a-6b+12-6a+2b-7

3a-6a-6b+2b+12-7

-3a-4b+5

A study was conducted to determine the percent of children that want to grow up work in the same career as a parent. In a sample

Irina-Kira [14]

Answer:

Step-by-step explanation:

From the information given,

Number of sample, n = 200

Probability of success, p = 43/100 = 0.43

q = 1 - p = 1 - 0.43

q = 0.57

For a confidence level of 95%, the corresponding z value is 1.96.

The formula for determining the error bound for the proportion is

z × √pq/n

= 1.96 ×√(0.43 × 0.57)/200

= 1.96 × 0.035 = 0.0686

The upper boundary of the population proportion is

0.43 + 0.0686 = 0.5

The lower boundary of the population proportion is

0.43 - 0.0686 = 0.4

The error in the solution is

phat = 0.43/200 = 0.00215

Also,

[-0.0043, 0.0086] is wrong

How do you do this!?!

Andrei [34K]

11x + y = 4

x | y

0 | 4

$\frac{4}{11}$ | 0

plot the y-intercept (0, 4) and the x-intercept ( $\frac{4}{11}$ , 0)

or

11x + y = 4

-11x -11x

y = -11x + 4 ⇒ m = $\frac{-11}{1}$ , b = 4

plot at point the y-intercept "b = 4" (0,4). plot the next point using the slope "m = $\frac{-11}{1}$ " from point (0,4), count down 11 and to the right 1 (1,-7).

Using intercepts would not provide an accurate graph because you have to estimte where ( $\frac{4}{11}$ , 0) is, so it is best to use slope-intercept form.

***********************************************************************************************************

x + y = -2

x | y

0 | -2

-2 | 0

plot the y-intercept (0, -2) and the x-intercept (-2, 0)

or

x + y = -2

-x -x

y = -x - 2 ⇒ m = $\frac{-1}{1}$ , b = -2

plot at point the y-intercept "b = -2" (0,-2). plot the next point using the slope "m = $\frac{-1}{1}$ " from point (0,-2), count down 1 and to the right 1 (1,-3).

Both methods are easy to use so either can be used.

**********************************************************************************************************

x - 2y = 18

x | y

0 | -9

18 | 0

plot the y-intercept (0, -9) and the x-intercept (18, 0)

or

x - 2y = 18

-x -x

-2y = -x + 18

$\frac{-2y}{-2} = \frac{-1}{-2}x + \frac{18}{-9}$

y = $\frac{1}{2}x$ - 9

plot at point the y-intercept "b = -9" (0,-9). plot the next point using the slope "m = $\frac{1}{2}$ " from point (0,-9), count up 1 and to the right 2 (2,-8).

Using intercepts will make a large graph since you have to plot (18,0) so it is best to use the slope-intercept form.

Write a short story about an inanimate object. You may use personification or anthropomorphism.

KATRIN_1 [288]

Answer:

There once was a house. The house moaned and groaned all night long. The people living in it believed that it was haunted. Every night starting at 12:00 A.M. the creaking and groaning of the house began. "CREEEEEEAK!" said the house. "GROAAAAAANNNN" exclaimed the house. Then one day the child, who lived with his parents and his dog in that house, read a book about the noise of a house. The book explained that the creaking and groaning that he and his parents heard was the house settling. The mystery on the creaking was solved.
