Answer:
C
Explanation:
I think you’re asking what graph goes with D = {x|x≠0} and R = {all real numbers}, which would be C. The reason being is that because x≠0, you need an open dot to represent 0 not being on the line. B has a closed dot, meaning 0 is included, which isn’t what it’s asking for.
Answer:
$36,000
Step-by-step explanation:
Given:
Bryce pays $240,000 for a property, then sells it for 15% less of what he bought is for.
To find:
15% of $240,000 to find the total loss.
__
<h3>steps</h3>
Step 1: Our output value is 240000.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above,
Step 4: Similarly,
Step 5: This results in a pair of simple equations:
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
Step 7: Again, the reciprocal of both sides gives
Therefore,
So if he lost 15% of $240,000, he lost $36,000.
So now we subtract.
240,000 - 36,000
= $204,000
Hence, the total loss of the property was $36,000

Answer:
v, measuring liquid is volume
We are given the following variables:
μ = the sample mean = 152 pounds
σ = the standard deviation = 26 pounds
x = the sample value we want to test = 180 pounds
n = the sample size = unknown
MOE = margin of error = 4% = 0.04
Confidence level = 96%
The first thing we can do is to find for the value of z
using the formula:
z = (x – μ) / σ
z = (180 – 152) / 26
z = 1.0769 = 1.08
Since we are looking for the people who weigh more than
180 pounds, therefore this is a right tailed z test. The p value is:
p = 0.1401
Then we can use the formula below to solve for n:
n = z^2 * p * (1 – p) / (MOE)^2
n = 1.08^2 * 0.1401 * (1 – 0.1401) / (0.04)^2
n = 87.82 = 88
Therefore around 88 people must be surveyed.
