A leaky pool loses 21/4 inches of water each day. Jermaine and Mildred are asked to determine the change in the amount of water

in the pool over 5 days. Jermaine's solution. Mildred's solution
5(-2 1/4) 5(-2 1/4)
5(-2 -1/4) 5(-2 -1/4)
-10 -1/4. -10 -5/4
-10 1/4. -11 1/4

Which describes the reasoning used to determine whose solution is correct?

A. Jermaine is correct because -10 -1/4 equals -10 1/4.
B. Jermaine is correct because he distributed 5 correctly.
C. Mildred is correct becaude she multiplied 5 by -2 but not by -1/4.
D. Mildred is correct becajse she distributed 5 correctly.

D. Mildred is correct because she distributed 5 correctly

I am not quite sure which side is which person, but the correct answer is to distribute the 5 to both -2 and -1/4. This would result in -10 and -5/4. This would be equivalent to -11 1/4.

The relative frequencies for the given table are:

  • Male → 13/44
  • Female →  17/86
  • Adult → 29/86
  • Baby → 7/43

<h3>How to get the relative frequencies?</h3>

The relative frequency of a given element out of a set, is given by the quotient between the number of that element and the total number of the set.

Here we can see that the total number of moose is:

52 + 34 + 58 + 28 = 172

There are 52 male moose, then the relative frequency for male moose is:

M = 52/172 = 26/86 = 13/44

There are 34 female moose, then the relative frequency is:

F = 34/172 = 17/86

There are 58 adult moose, so the relative frequency is:

A = 58/172 = 29/86

There are 28 baby moose, so the relative frequency is:

B = 28/172 = 14/86 = 7/43

A function f(x) = x^2 - 4 has a domain as the set of integers
mel-nik [20]

Answer:

8

Step-by-step explanation:

f(x) = (x+2)(x-2)

Substituting x=1 into f(x):

f(1) = 3*-1

     = -3

Since -2 & 2 touch the x-axis, 1 has a negative y value, 2 has a y value of 0, and all values from 2, are positive.

Hence,

3, 4, 5, 6, 7, 8, 9, 10 are all positive. Therefore, the answer is 8

This can be confirmed with a graph, as attached below.

How can the Pythagorean theorem be used to help classify triangles
kompoz [17]

Answer:

We can use the Pythagorean Theorem to help determine if a triangle is a right triangle, if it is acute, or if it is obtuse. ... Conversely, if \begin{align*}a^2 + b^2 < c^2\end{align*}, then lengths \begin{align*}a, \ b\end{align*}, and \begin{align*}c\end{align*} make up the sides of an obtuse triangle.
