kvv77 [185]

Answer:

The correct answer is:

None of the above

Step-by-step explanation:

I didn't find any of these answer choices to be the solution for x.

I'm sorry that I couldn't find the answer.

Find the coordinates of the endpoint A given B (-3,5) is the midpoint of AC and C (1,-2)

WARRIOR [948]

coordinates of endpoint A are (-7,12)

Step-by-step explanation:

We are given midpoint B (x,y) =(-3,5)

One endpoint C (x₂,y₂)= (1,-2)

We need to find other endpoint A (x₁,y₁).

The formula to find midpoint is:

$x=\frac{x_{1}+x_{2}}{2}\\y=\frac{y_{1}+y_{2}}{2}$

We can find the coordinates of endpoint A using these formula.

We have x=-3, x₁=? and x₂= 1

Putting values and finding x₁

$x=\frac{x_{1}+x_{2}}{2}\\-3=\frac{x_{1}+1}{2}\\-6=x_{1}+1\\-6-1=x_{1}\\x_{1}=-7$

Now, y=5, y₁=? and y₂= -2

$y=\frac{y_{1}+y_{2}}{2}\\5=\frac{y_{1}+-2}{2}\\5*2=y_{1}+-2\\10=y_{1}+-2\\10+2=y_{1}\\y_{1}=12$

SO, coordinates of endpoint A are (-7,12)

Tumor counts: A cancer laboratory is estimating the rate of tumorigenesis in two strains of mice, A and B. They have tumor count

Igoryamba

Answer:

The observed tumor counts for the two populations of mice are:

Type A mice = 10 * 12 = 120 counts

Type B mice = 13 * 12 = 156 counts

Step-by-step explanation:

Since type B mice are related to type A mice and given that type A mice have tumor counts that are approximately Poisson-distributed with a mean of 12, we can then assume that the mean of type A mice tumor count rate is equal to the mean of type B mice tumor count rate.

This is because the Poisson distribution can be used to approximate the the mean and variance of unknown data (type B mice count rate) using known data (type A mice tumor count rate). And the Poisson distribution gives the probability of an occurrence within a specified time interval.

Which terms could be used as the first term of the expression below to create a polynomial written in standard form? Select five

vovikov84 [41]

Option C: $-6rs^5$

The last two terms given of the standard polynomial are:

$\cdots + 8r^2s^4 + 3r^3s^3$

This shows 2 patterns to us:

r 's degree is increasing per term in the given polynomial.

s 's degree is decreasing per term in the given polynomial.

The sum of powers of variates r and s is 2+4 = 3+3 = 6.

And since standard polynomial, the same pattern must be present in all terms of the series.

All options except C are not valid.

Option C has term $-6rs^5$ for which r's degree plus s's degree is 1 + 5 = 6.

And r's degree 1 < s's degree 5.

Thus its a valid term to be putted as first term in standard form of polynomial in consideration.

Thus Option C: $-6rs^5$ is the needed expression.
