Step-by-step explanation:
x^2-2 x=3
Substitute the x to 3 and use Gema and/or Pemdas
3^2= 9
9-2= 7
Final answer: 7You have only 1,000$. The price of a TV-set is 1,150$. Can you buy the TV if you get 10% discount?
Answer:
No,I think?
Step-by-step explanation:
Money we have = $1000
Cost of TV set = $1150
10% discount on TV set = $1150 × 10 / 100 (or you can use 10% instead of 10/100)
=$115
Original cost of TV set - 10% of discount on TV set
= $1150 - $115
= $ 1035
since the cost of TV set is greater than the money you have which is (1036 is greater than 1000).You still can't buy the TV set.
Hope it helps you,I might be wrong^^

Determine whether the given value is a statistic or a parameter. A sample of seniors is selected and it is found that 65% own a television. A. Statistic because the value is a numerical measurement describing a characteristic of a sample. B. Parameter because the value is a numerical measurement describing a characteristic of a sample. C. Statistic because the value is a numerical measurement describing a characteristic of a population. D. Parameter because the value is a numerical measurement describing a characteristic of a population.
Answer: A. Statistic because the value is a numerical measurement describing a characteristic of a sample.
Step-by-step explanation: Statistic are used to describe values obtained from a data sample which are regarded as a subset of the data belonging to an entire population. Therefore, in statistical parlance, numerical measurement obtained from such dataset are called statistic. On the other hand, if data from which a numerical derivation was made is a population which consists of the entire set of observations belonging to a particular group of interest, then the numerical values obtained are referred to as a parameter.
Given: The value [tex]65[/tex]% is a statistic.
The correct option is C (Statistic because the value is a numerical measurement describing a characteristic of a population).
Explanation: We have to determine whether the underlined number is statistics or a parameter.
A sample of employees is selected and it is found that [tex]65[/tex]% own a television.

The equation is y=4x-3.
–4(2x−2)= –(4x−4) what is x?
Answer:
x = 1
Step-by-step explanation:
–4(2x−2)= –(4x−4)
-8x-(-8) = -4x-(-4)
-8x+8 = -4x+4
-8x+8-8 = -4x+4-8
-8x = -4x+(-4)
-8x+4x = -4x+4x+(-4)
-4x = -4
-4x/-4 = -4/-4
x = 1

State whether the data described below are discrete or continuous, and explain why.
The exact heights of different elephants. Choose the correct answer below.
A. The data are continuous because the data can take on any value in an interval.
B. The data are discrete because the data can only take on specific values.
C. The data are continuous because the data can only take on specific values.
D. The data are discrete because the data can take on any value in an interval.
Answer:
A. The data are continuous because the data can take on any value in an interval.
Step-by-step explanation:
A continuous data is any data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous data.
Hence, the exact heights of different elephants represents a continuous data because the data can take on any value in an interval.
On the other hand, a discrete data is any data set in which the number of possible values are either finite or countable. Thus, a discrete data can only take on specific values. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.

pls help
im ready to got bed
lol
Answer:
x=-5 Hope this helped! Goodnight!
Step-by-step explanation:
Let's solve your equation step-by-step.
−3(2x+6)=12
Step 1: Simplify both sides of the equation.
−3(2x+6)=12
(−3)(2x)+(−3)(6)=12(Distribute)
−6x+−18=12
−6x−18=12
Step 2: Add 18 to both sides.
−6x−18+18=12+18
−6x=30
Step 3: Divide both sides by -6.
−6x /−6 = 30 /−6
x=-5
Answer:
x= -5

Choose 1 answer: Choose 1 answer: (Choice A) A Ioana used an invalid reason to justify the congruence of a pair of sides or angles. (Choice B) B Ioana only established some of the necessary conditions for a congruence criterion. (Choice C) C Ioana established all necessary conditions, but then used an inappropriate congruence criterion. (Choice D) D Ioana used a criterion that does not guarantee congruence.
Answer:
The answer is Choice C
Step-by-step explanation:
I got it right, look at the screenshot for proof
Answer:
Choice C
Step-by-step explanation:
Writing a proof
A proof is a formal description of how we can know that something is true based on the information from a mathematical scenario.
Each step of the proof is a transformation, a construction, or a statement about what we can conclude from earlier steps.
For a two-column proof we give a reason to justify each statement. Common reasons include geometric theorems, algebraic properties, and information given in diagrams.
Let's check the reason for each step and whether Ioana established the conditions for it.
Hint #22 / 4
Step 1
The diagram does support the claim that PQ=RQ=9PQ=RQ=9P, Q, equals, R, Q, equals, 9.
Step 1 is correct.
Step 2
The diagram does support the claim that m\angle O=m\angle S=90\degreem∠O=m∠S=90°m, angle, O, equals, m, angle, S, equals, 90, degree.
Step 2 is correct.
Step 3
The diagram does support the claim that m\angle PQO=m\angle RQS=63\degreem∠PQO=m∠RQS=63°m, angle, P, Q, O, equals, m, angle, R, Q, S, equals, 63, degree.
Step 3 is correct.
Hint #33 / 4
Step 4
In this step, Ioana claims that \triangle OPQ\cong \triangle SRQ△OPQ≅△SRQtriangle, O, P, Q, \cong, triangle, S, R, Q using the angle-side-angle criterion. But the corresponding pair of congruent sides, \overline{PQ}
PQ
start overline, P, Q, end overline and \overline{RQ}
RQ
start overline, R, Q, end overline, aren't the sides that are included between the two pairs of congruent corresponding angles.
Ioana should have used the angle-angle-side criterion.
Hint #44 / 4
Ioana established all necessary conditions, but then used an inappropriate congruence criterion.
What characteristics make terms "like terms?"
Answer:
same variable and same exponent
Answer:
when they have the same variable and their exponent if applicable isn't different.
Step-by-step explanation:
For example if you have a value like 3x and 4x they are like terms that can be combined;7x. If you have say 5x and 6y they are not like terms.
The second option would be your answer.
