Answer:
A. 6.89 m
Step-by-step explanation:
Pythagorean Theorem.
a^2+b^2=c^2
(1.5)^2 + (3.6)^2 = c^2
2.25 + 12.96 = 15.21
√15.21= 3.9
find the ratio from the the left triangle to the other -
2.65÷1.5= 1.766666 × 3.69 = 6.89
Answer:
x(7 - x)
Step-by-step explanation:
Given
7x - x² ← factor out x from both terms
= x(7 - x) ← in factored form
Answer:
No, because water temperature is confounded with brand of detergent.
Step-by-step explanation:
There is a very possible chance of allowing a third or confounding variable to have creepwd into the research. The aim was to investigate which of two detergents prevents color from fading. Hence, the test for both detergents should be carried out under the same research condition. However, with adoption of different water temperature for each of detergent A and B, there may be a relationship between fading and water temperature which is not what are trying to investigate. This difference in temperature will thus cause a spurious relationship in our research. Hence, water temperature has been confounded with detergent brand, making this experimental design a bad one.
Answer:
12+2√6+2√10
Step-by-step explanation:
(√2+√3)² + (√5+√2)²=2+3+2√6+5+2+2√10=12+2√6+2√10
