to multiply it by its sell for example 8 is 64
From A to B...
distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2
(-3,1)....x1 = -3 and y1 = 1
(1,3)....x2 = 1 and y2 = 3
sub
d = sqrt ((1 - (-3)^2 + (3 - 1)^2
d = sqrt ((1 + 3)^2 + 2^2
d = sqrt (4^2 + 2^2)
d = sqrt (16 + 4)
d = sqrt 20
d = 4.47 miles...so from A to B, it was 4.47 miles
from B to C
d = sqrt ((x2 - x1)^2 + (y2 - y1)^2
(1,3)....x1 = 1 and y1 = 3
(5,-1)...x2 = 5 and y2 = 1
sub
d = sqrt ((5 - 1)^2 + (-1 - 3)^2
d = sqrt ((4^2 + (-4^2)
d = sqrt (16 + 16)
d = sqrt 32
d = 5.66......but keep in mind, he only drove half-way...so 5.66/2 = 2.83 miles
for a total of : 4.47 + 2.83 = 7.3 miles <===
Answer:
1/216
Step-by-step explanation:
The ratio of volumes of similar shapes is the cube of the scale factor. The filled portion of the cone is similar to the entire cone.
<h3>Linear scale factor</h3>
If the filled height is 1/6 of the total height, the scale factor for linear dimensions is 1/6.
<h3>Volume scale factor</h3>
The scale factor for the volume is the cube of the scale factor for linear dimensions. it is ...
(1/6)³ = 1/216
The volume of the filled portion of the cup is 1/216 of the volume of the cup.
Answer:
The bias most likely to be present in the survey results is;
Option A; This is question wording bias because the survey question attempts to influence subjects’ responses.
Step-by-step explanation:
A bias occurs when a group or outcome is intentionally or unintentionally favored over another group or outcome in the a general population.
There are two main types which are;
- Selection bias which includes; Non - response bias, non representative sample and voluntary bias
- Response Bias which includes wording bias, extreme responses, neutral responses e.t.c
Let's look at each of the options;
Option A; This is correct because what occurred is that the concerned student by telling the adults adverse effect of plastics in our environment, he is indirectly influencing the adults to have a bad mindset about the plastics. He is leading them on by the way he phrased the word to ask the question.
Option B; This is not the reason why it is a response bias. The reason it is a response bias is because he led them on with his wording of the question.
Option C; Like said in Option A & B above, the scenario is that of a response bias since they are giving answers.
Option D; Voluntary response bias is a type of non-response bias and so it is not correct here
Answer:
See Explanation
Step-by-step explanation:
Given
Required
Make the variable in bracket the subject
From the given expression, none of the variables (m and x) are in brackets.
So, I will solve for m and then solve for x
Solving for m:
Subtract 2x from both sides
Divide both sides by x
Solving for x:
Factorize
Divide both sides by m + 2
