(8x-11)-(15-x)=1 dont know where to start with it​
schepotkina [342]

Answer:

<em>x</em><em> </em><em>=</em><em> </em><em>3</em>

Step-by-step explanation:

First open the brackets. While opening brackets, you've to be careful about signs. So when you open bracket of <em>(</em><em>1</em><em>5</em><em>-</em><em>x</em><em>)</em>, there's <em>negative</em> sign in front of it, so it makes the signs inside the brackets to change. Then you solve the it.

Point T is the midpoint of . The coordinate of T is (0, 4) and the coordinate of J is (0, 2). The coordinate of H is: (0, 6) (0,
Anuta_ua [19.1K]
Point T is the midpoint of J and H.

x-coordinate is 0 for the three points.

y-coordinate of T is in the middle of the y-coordinate of J and the y-coordinate of H. So, y-coordinate of H has to be 6, because (6+2)/2=8/2=4.

Then point H is (0,6).

A machine is designed to fill 16-ounce bottles of shampoo. When the machine is working properly, the amount poured into the bott
Andreyy89

Answer:

(15.8495,16.2505)  

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 16.05 ounces

Standard Deviation, σ = 0.2005 ounces

We are given that the distribution of amount poured into the bottles is a bell shaped distribution that is a normal distribution.

Empirical rule:

  • It states that for a normal distribution, almost all data falls within three standard deviations (denoted by σ) of the mean (denoted by µ).
  1. It shows that 68% falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ).

Confidence interval:

\mu \pm 2\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

16.05 \pm 2(\frac{0.2005}{\sqrt{4}} ) = 16.05 \pm 0.2005 = (15.8495,16.2505)

Factor the polynomial:81m+48mn
Anton [14]
To factor this polynomial you will have to first find the GCF of 81 and 48 and its 3.

So then you put 3 out the parentheses. 3(----).

Then you have to see how many times 3 goes into 81m and 48m. It is 27m and 16mn.

So then this is what you get, 3(27m-16mn)

Hope it helps you!!!
