Answer:

x=5,x=-5

Step-by-step explanation:

x^2-25=0

Add 25 to both sides:

x^2-25+25=0+25

x^2=25

Square root both sides:

x=\sqrt{25},\:x=-\sqrt{25} (Since a negative number multiplied by itself gives positive, there are two answers.)

x=5,x=-5

Hey there!

<h3>ANSWER: x=5\\x=25</h3><h2>EXPLANATION:</h2>

x^2-25=0

The first step we have to do is to add 25 to both sides of the equation.

x^2-25+25=0+25\\\text {equals }x^2=25

In our last and final step, we will have to take the square root.

x= ±\sqrt{25}

We have two answers.

x=5(ANSWER)\\x=-5(ANSWER)

Hope this helps!

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.

A shop has this offer.

49x3= 147 so 10 reduction will make tim spend 137. 49x5= 245 so 20 reduction will make Craig spend 225. 225-147= 78 so Craig spends 78£ more than tim. All the offers state “X or Y” meaning it’s one or the other hence the ‘or’. Atleast that’s my interpretation of it.
