awh happy holidays to you too!! and ty for this
Answer:
The critical value can be founded in the normal standard distribution table using the value of and we got . Replacing the info given we got:
Step-by-step explanation:
For this case we have the following info given:
represent the population deviation
represent the sample mean
represent the sample size
And we want to find the margin of error for a confidence level of 95%. So then the significance level would be and . The margin of error is given by:
The critical value can be founded in the normal standard distribution table using the value of and we got . Replacing the info given we got:
Answer:
The answer is A. Objects that have the same size and shape.
Step-by-step explanation:
In geometry, two figures or objects are congruent if they have the same size or shape, or if one has the same shape and size as the mirror image of the other.
Answer:
Abel to Ben: 6
Abel to Carl: 3
Ben to Carl: 0.5
Step-by-step explanation:
First we formulate the problem in equations:
Abel = 6 * Ben
Cale = Abel / 3
If Cale's score is Abel's score over 3, so Abel's score is 3 times Cale's score.
If Abel's score is 6 times Ben's score, and 3 times Cale's score, then Cale's score is 2 times Ben's score (so Ben's score is 0.5 times Cale's score)
So, the ratio between all scores are the following:
Abel to Ben: 6
Abel to Carl: 3
Ben to Carl: 0.5
Answer:
<u>(-3, -10)</u>
Step-by-step explanation:
We are asked to solve the system of equations simultaneously.
We need to equate the equations.
=============================================================
Solving :
⇒ -4 + 2x = 4x + 2
⇒ 4x - 2x = -4 - 2
⇒ 2x = -6
⇒ x = -3
============================================================
Finding y :
⇒ y = 4(-3) + 2
⇒ y = -12 + 2
⇒ y = -10
============================================================
Hence, the solution :
<u>(-3, -10)</u>
