Mathematics
1 answer:
kherson [118]3 years ago
6 0

Answer:

6

Step 1: Solve Square Root

Vx+3=x-3

x+3=(x-3)^2 (squared both sides)

x+3=x^2-6x+9

x+3-(x^2-6x+9)=0

(-x+1)(x-6)=0 (factor left side of equation)

-x+1=0 or x-6=0

x=1 or x=6

When you plug it in to check

1 (Doesn't Work)

6 (Work)

Therefore, 6 is your solution.

In the number 5.3779, how does the value of 7 in the hundredths place compare to the value of the 7 in the thousandth place?
anygoal [31]

Answer:

  (b)

Step-by-step explanation:

The hundredths place is immediately to the left of the thousandths place. In our base-10 number system, moving a digit to the left one place increases its value by a factor of 10.

The value of 7 in the hundredths place is 10 times the value of 7 in the thousandths place.

Which of the following about the normal distribution is not​ true?
Lostsunrise [7]

Answer:

Normal distribution is a Continuous distribution.

Step-by-step explanation:

Normal Distribution:

The following information is true about normal distribution.

  • ​Theoretically, the​ mean, median, and mode are the same.
  • Its parameters are the​ mean, mu​, and standard​ deviation, sigma.
  • About two thirds of the observations fall within plus or minus 1 standard deviation from the mean.

But normal distribution is not a discrete distribution. It is a continuous distribution.

  • The normal distribution is a continuous probability distribution. This has several implications for probability.
  • The probability that a normal random variable X equals any particular value is 0.
