The possible error made by Beth is directly multiplying scale of 5 to area of original triangle and getting area of enlarged triangle, which is wrong.
Step-by-step explanation:
Originally Triangle has height =3.5cm and width=4cm
Beth enlarged the same triangle by scale of 5 and calculate area of triangle
The area of triangle as given as A=
Area of original triangle is A =
Since, The triangle is enlarged by scale of 5
New height =3.5x5 = cm and new width=4x5cm
Area of new triangle is
A' =
A' =
A' =
A' =
Now, Looking what error beth made is:
Beth found Area of new triangle is A' =
The possible error made by Beth is directly multiplying scale of 5 to area of original triangle and getting area of enlarged triangle, which is wrong.
So that when you add divide or multiply the three sides you get your complete answer length times width times height.
The numbers are constants, and the multiplication symbol is an operator.
If this equation were 4x * 6 = 24, then 4 would be a coefficient and x would be a variable. 6 and 24 are still constants and the multiplication symbol is still an operator.
Answer:
Step-by-step explanation:
9. the set containing all objects or elements and of which all other sets are subsets.
10. complement --> the amount in only one of teh sets
intersection --> the amount in both sets
11. 14 or -14
13. 46 1/2
14. 2 31/120
15. 1100% profit
16. 1200 gm
17. cube root of 7?
18. 6000 per year
Based on the calculations, the correct value of the test statistic is equal to 3.2.
<h3>How to calculate value of the test statistic?</h3>
For samples A and B, the hypothesis is given by:
H₀: μ₁ ≤ μ₂
H₁: μ₁ > μ₂
Since both samples have a normal distribution, we would use a pooled z-test to determine the value of the test statistic:
Substituting the given parameters into the formula, we have;
z = 3.2.
