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

data for 10 mice in strain A and 13 mice in strain B. Type A mice have been well studied, and information from other laboratories suggests that type A mice have tumor counts that are approximately Poisson-distributed with a mean of 12. Tumor count rates for type B mice are unknown, but type B mice are related to type A mice. The observed tumor counts for the two populations are

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.

Point Y is the midpoint of segment XZ. If XY = 2(3x +1) and YZ = 5x + 22, find the value of x.
Ede4ka [16]
<h3>Point Y is the midpoint of segment XZ. Then value of x is 20</h3>

<em><u>Solution:</u></em>

Given that,

<em><u>Point Y is the midpoint of segment XZ</u></em>

XY = 2(3x +1)

YZ = 5x + 22

To find: Value of x

Since, Point Y is the midpoint of segment XZ,

Therefore,

XY = YZ

2(3x + 1) = 5x + 22

6x + 2 = 5x + 22

6x - 5x = 22 - 2

<h3>x = 20</h3>

Thus, value of x is 20

Rufina [12.5K]

Answer:

  (2, 0)

Step-by-step explanation:

The only table entry with y = 0 is (x, y) = (2, 0). That is the x-intercept.

A 6 foot long board is propped against the wall of a house. The board forms a 60 degree angle with the ground. How far is the ba
Zarrin [17]
To solve this problem you must apply the proccedure shown below:
 1. You have that  the lenght ot the board is 6 feet and <span> forms a 60 degree angle with the ground. Therefore, you have:
 Sin</span>α=opposite/hypotenuse
 α=60°
 opposite=x
 hypotenuse=6
 2. When you substitute the values, you obtain:
 Sin(60°)=x/6
 3. Now, you must solve for x, as following:
 x=6Sin(60°)
 x=5.19
 Therefore, the answer is: 5.19 feet.
