X+2x=9what does x equal? and how do I get the answer?

Mathematics

Leno4ka [110]3 years ago

add like terms on the left side (x + 2x), then isolate the variable on the left side by dividing both sides by 3.

x + 2x = 9        

    3x = 9           <em>added like terms</em>

     x = 3             <em>divided both sides by 3</em>

Answer: 3

Give the equivalent numerator if the denominator is x³y².
gayaneshka [121]
x³y²
 For this case, the first thing you should know is the properties of the exponents.
 Let's write the full fraction:
 (1) / (x ^ 3 * y ^ 2)
 We have that by power properties:
 (1) / (x ^ 3 * y ^ 2) = x ^ -3 * y ^ -2
 Therefore the equivalent numerator is:
 x ^ -3 * y ^ -2
 Answer:
 x ^ -3 * y ^ -2

Given a normal population which has a mean of 110 and a standard deviation of 5, find the probability that a random sample of 49
Mrac [35]

Answer:

0.9168

Step-by-step explanation:

From the data given:

Mean = 110

standard deviation = 5

Let consider a random sample n =49 which have a mean between 109 and 112.

The test statistics can be computed as:

Z_1 = \dfrac{x- \bar x}{\dfrac{\sigma}{\sqrt{n}}}

Z_1 = \dfrac{109- 110}{\dfrac{5}{\sqrt{49}}}

Z_1= \dfrac{-1}{\dfrac{5}{7}}

Z_1  = -1.4

Z_2= \dfrac{x- \bar x}{\dfrac{\sigma}{\sqrt{n}}}

Z_2 = \dfrac{112- 110}{\dfrac{5}{\sqrt{49}}}

Z_2 = \dfrac{2}{\dfrac{5}{7}}

Z_2 =2.8

Thus; P(109  <  \overline x  <  112) = P( - 1.4 < Z < 2.8)

= P(Z < 2.8) - P( Z < -1.4)

= 0.9974 - 0.0806

= 0.9168
