Here is an inequality: -2x > 10.
1. List some values for x that would make this inequality true.
Answer: Any negative number above -5, like -6, -7, etc.

2. How are the solutions to the inequality -2x ≥ 10 different from the solutions to
-2x > 10? Explain your reasoning.

Answers

Answer:

  -5 is included in the solution set of the first, but not the second

Step-by-step explanation:

The solution to -2 ≥ 10 is x ≤ -5. The solution to -2x > 10 is x < -5. The difference is that x = -5 is included in the solution set of the first inequality, but is not included in the solution set of the second inequality.

When plotted on a number line, the former inequality has a solid dot at -5, indicating that point is included. The latter inequality has an open dot (circle) at -5, indicating that point is not included. (Both plots are shaded to the left of the dot.)

Mean of eight observations is 25. If one observation 11 is excluded , find the mean of the remaining.​

Answers

Answer:

Mean = 27

Step-by-step explanation:

Given mean = 25

No of observations (N) = 8

We know,

Mean = Sum / N

25 = Sum / 8

Sum = 25 x 8

Sum = 200

Since an observation 11 is removed,

New sum = 200 - 11 = 189

New no. of observation (N) = 8 - 1 = 7

Now,

Mean of remaining observations = New Sum / New N

= 189/7

= 27

Answer:

mean=25

n=8

sum of observation=?

we have

mean=sum/n

sum=25×8=200

if one observation is excluded

sum will be =200-11=189

[n]no of observation = 8-1=7

new mean =new sum/new n=189/7=27

the mean of the remaining is 27

Stephanie accidentally hit a golf ball through her neighbor's square window with a side length of x she needs to buy a new piece of glass to replace the one she broke write a variable expression for the area of the glass piece Stephanie needs to replace remember x is your variable​

Answers

Answer:the window is square so it's 20*x and then for the next parts it's 400 divided by 100 to get.how.much she can spend which is 4

Step-by-step explanation:

Answer:

x^2 = a

Step-by-step explanation:

Since the window is a square, that means all sides equal to the same thing. If you don't understand; if we look at all the sides you'll see that they all are the same in size. Let's say the number for x is 10. You'd multiply 10 by 10 and get 100 square inches.

x^2 (or x * x) will equal to the area of the square window.

The attendance at a baseball game was 400 people. Adult seats sold for $15 and children seats sold for $10. Total ticket sales were $4560. How many of each type of ticket were sold?

Answers

Answer:

112 adult and 288 children

Step-by-step explanation:

x= adult seats

y= children seats

15x + 10y = 4560

x + y = 400 --> y=400-x

so plug 400-x for y in the other equation

15x + 10(400-x)= 4560

now solve this equation

15x + 10(400-x)= 4560 --> 15x + 4000-10x= 4560 --> 15x -10x = 560 --> 5x=560 --> x = 560/5 --> x= 112

now plug in 112 for this equation (x+y=400) --> 112+y=400 --> y= 288
