−3 Which is the correct graph for the compound inequality

Answers

The correct graph for the compound inequality is the third graph.

Graph of Inequality

From the question, we are to determine the correct graph to the given compound inequality

The given compound inequality is

-3 < x ≤ 4

This means

-3 < x and x ≤ 4

That is,

x > -3 and x ≤ 4

The graph of x > -3 will start at -3 on the number line without shading the circle and it will point in the right direction

The graph of x ≤ 4 will start at 4 on the number line, with the circle shaded, and it will point towards the left

Joining the two graphs, we will get a number line starting at -3, unshaded, and ending at 4 shaded.

Hence, the correct graph for the compound inequality is the third graph.

how much larger is the combined debt of the three most populous states than of the three least populous states? Express your answer in scientific notation. Three most populous- 1.02 X 10*10 Three least populous- 1 X 10*10

Answers

The combined debt of the three most populous states is -2 × 10⁹ bigger than that of the three least populous states.

What is the arithmetic operator?

Summarization, subtraction, division, and multiplication are the four fundamental mathematical operations covered under the term "arithmetic operators."

Given the combined debt of ;

Most populous = -1.02 × 10¹⁰

Least populous = -1 × 10¹⁰

Most populous - Least populous ⇒

( -1.02 × 10¹⁰) - (-1 × 10¹⁰)

⇒ -0.2 × 10¹⁰

Multiply and divide by 10

⇒ -0.2 × 10/10 × 10¹⁰

Based on these results, express the probability that the next chew Qasim removes from the bag will be lemon chew as a percent to the nearest whole number. Answer: Submit Answer attempt 2 out of 2​

Answers

The probability that the next chew that Qasim will remove from the bag will be lemon chew is 0.17

What is probability ?

Probability is the chance that an event will occur or we can say the chance for how many time an event can occur describes the probability of that event .

Probability =  Preferred Outcome/Total outcome

Probability is always between 0 to 1 i.e. we can say the lowest value of probability is 0 where no outcome is preferable  and the highest value is 1 where all the outcomes are preferable outcomes.

In the question,

If Qasim performs the experiment 52 times of removing a chew from the bag the total outcome = 52

If a pineapple chew was selected 33 times. A lemon chew was selected 9 times. A lime chew was selected 10 times, the probability that  next chew Qasim will remove from the bag will be  the lemon chew  is 9/52 or 0.17 percent.

Point P is located 3/5 of the way from point A to point E. Point A is located at (-1, -1) and point P is located


at (-7,5). What are the coordinates for point E?

Answers

By using the line segment formula, we conclude that the coordinates of point E are E(x, y) = (- 11, 9).

How to determine the coordinates of the missing endpoint of a line segment

In this problem we find a line segment of which the coordinates of an endpoint and a point within the segment and in accordance with a segment ratio are known. The coordinates of the other endpoint must be found in accordance with the following expression:

E(x, y) = A(x, y) + k · [P(x, y) - A(x, y)]          (1)

Where E(x, y) is the missing endpoint.

If we know that A(x, y) = (- 1, - 1), P(x, y) = (- 7, 5) and k = 5 / 3, then the coordinates of point E are:

E(x, y) = (- 1, - 1) + (5 / 3) · [(- 7, 5) - (- 1, - 1)]

E(x, y) = (- 1, - 1) + (5 / 3) · (- 6, 6)

E(x, y) = (- 1, - 1) + (- 10, 10)

E(x, y) = (- 11, 9)

area of the composite figure = area of the triangle + area of the parallelogram

area of the triangle = 1 / 2 bh

area of the triangle = 1 / 2 × 8 × 2

area of the triangle = 16 / 2

It's such a relief to talk when one wants to and not be told that children should be seen and not heard. I've had that said to me a million times if I have once. And people laugh at me because I use big words. But if you have big ideas you have to use big words to express them, haven't you?""Well now, that seems reasonable," said Matthew."Mrs. Spencer said that my tongue must be hung in the middle. But it isn'tit's firmly fastened at one end. Mrs. Spencer said your place was named Green Gables. I asked her all about it. And she said there were trees all around it. I was gladder than ever. I just love trees. And there weren't any at all about the asylum, only a few poor weeny-teeny things out in front with little whitewashed cagey things about them. They just looked like orphans themselves, those trees did. It used to make me want to cry to look at them. I used to say to them, 'Oh, you POOR little things! If you were out in a great big woods with other trees all around you and little mosses and Junebells growing over your roots and a brook not far away and birds singing in you branches, you could grow, couldn't you? But you can't where you are. I know just exactly how you feel, little trees.' I felt sorry to leave them behind this morning. You do get so attached to things like that, don't you? Is there a brook anywhere near Green Gables? I forgot to ask Mrs. Spencer that.""Well now, yes, there's one right below the house.""Fancy. It's always been one of my dreams to live near a brook.

I can't feel exactly perfectly happy becausewell, what color would you call this?"She twitched one of her long glossy braids over her thin shoulder and held it up before Matthew's eyes. Matthew was not used to deciding on the tints of ladies' tresses, but in this case there couldn't be much doubt."It's red, ain't it?" he said.The girl let the braid drop back with a sigh that seemed to come from her very toes and to exhale forth all the sorrows of the ages."Yes, it's red," she said resignedly. "Now you see why I can't be perfectly happy. Nobody could who has red hair. I don't mind the other things so muchthe freckles and the green eyes and my skinniness. I can imagine them away. I can imagine that I have a beautiful rose-leaf complexion and lovely starry violet eyes. But I CANNOT imagine that red hair away. I do my best. I think to myself, 'Now my hair is a glorious black, black as the raven's wing.' But all the time I KNOW it is just plain red and it breaks my heart. It will be my lifelong sorrow. I read of a girl once in a novel who had a lifelong sorrow but it wasn't red hair. Her hair was pure gold rippling back from her alabaster brow. What is an alabaster brow? I never could find out. Can you tell me?""Well now, I'm afraid I can't," said Matthew, who was getting a little dizzy. He felt as he had once felt in his rash youth when another boy had enticed him on the merry-go-round at a picnic."Well, whatever it was it must have been something nice because she was divinely beautiful. Have you ever imagined what it must feel like to be divinely beautiful?""Well now, no, I haven't," confessed Matthew ingenuously."I have, often.
