Answer:3/2

how i did this

 Add 11 to both sides.

4x=5+1

Simplify 5+15+1 to 66.

4x=6

Divide both sides by 4

x= 6/4

Simplify 6/4 to 3/2

Awnser

x=3/2

Sorry if not helpful just trying my best :)

Multiply and simplify: –3x2y2 • x4 –3x5y2 9x5y2 –3x6y2 –3x5y6

Contact [7]

Answer:

Multiplying and simplifying the term $-3x^2y^2 \:.\: x^4$ we get $\mathbf{-3x^6y^2}$

Option C is correct option.

Step-by-step explanation:

We need to multiply and simplify: $-3x^2y^2 \:.\: x^4$

Simplifying the term:

$-3x^2y^2 \:.\: x^4$

While multiplying, the variables with same bases are multiplied: $a^m\:.\:a^n=a^{m+n}$

In the given question only x^2 and x^4 are variables with same bases, So we get:

$=-3(x^{2+4})y^2\\=-3x^6y^2$

So, multiplying and simplifying the term $-3x^2y^2 \:.\: x^4$ we get $\mathbf{-3x^6y^2}$

Option C is correct option.

What is the probability that the mean duration of the 24 rowers with idna exceeds 63 minutes?

statuscvo [17]

Answer:

Step-by-step explanation:

Given that: Training-session duration of female rowers with normal iron status is Normally distributed, with mean 69 minutes and standard deviation 18minutes.

Solution:

z score shows the relationship between sample means. The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by the formula:

$z=\frac{x-\mu}{\sigma}\\\\for\ sample(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} } \\\\where\ \mu=mean,\sigma=standard\ deviation,x=raw\ score$

Given that μ = 69 minutes, σ = 18 minutes, n = 24

For x > 63 minutes:

$z=\frac{x-\mu}{\sigma / \sqrt{n} } =\frac{63-69}{18/\sqrt{24} }=-1.63$

From the distribution table, P(x > 63) = P(z > -1.63) = 1 - P(z < 1.63) = 1 - 0.0516 = 0.9484
