B. Yes, this is a valid inference because the 35 families speak for the whole neighborhood
C. No, this is not a valid inference because she asked only 35 families
D. No, this is not a valid inference because she did not take a random sample of the neighborhood
Answer:
- 17
Step-by-step explanation:
hello :
5x + 25(34-x)= 510
divid by 5 : x +5(34-x)=102
x+ 170 -5x = 102
-4x =102-170
-4x = 68
x = 68/- 4 = - 17
How many pages will she read on the last night?
Answer:
Both triangles are right triangles because the angle d is 90 degrees in both sides
3 ^ 2 - 2.25^2 = 1.98
4^2 - 1.98^2 = 3.48
x = 3.48
Answer:
You would need to use the Pythagorean Theorem
Step-by-step explanation:
First, you would want to take the Hypotenuse of 3 and square. Do the same for the 2.25. After that, you want to put in a calculator (Desmos Graphing Calculator) √3²-2.25² adn get the answer for the line of C and D (-2.06). After that, you do the same but on the other side: Take the Hypotenuse of 4 and the -2.06 and form it into √4² -2.06². Your final answer would be...
x = 3.43
