Answer:
1. Number of warts on a toad ⇒ <em>discrete variable</em>
2. Survival time after poisoning ⇒ <em>continuous variable</em>
3. Temperature of porridge ⇒ <em>continuous variable</em>
4. Number of bread crumbs in 10 meters of trail ⇒ <em>discrete variable</em>
5. Length of wolves’ canines ⇒ <em>continuous variable</em>
A discrete variable is the one which takes over range of real number, for a value in range that variables are permitted to take, there is minimum distance to nearest permissible value. In contrast, continuous variables are the one which can take infinitely many values.
Answer: option b
Step-by-step explanation:
It is important to know that, by definition, the rule for 180 degrees counterclockwise rotation is:
→
Therefore, given the point (1, -6) we can find the image obtained for for a 180° counterclockwise rotation about the origin by applying the rule mentioned before.
Then, the image is:
→
Answer:
E. x² + 11x - 42 = 0
Step-by-step explanation:
let the square sides be x
A = bh = (x + 3 + 3)(x + 2 + 3) = 72
(x + 6)(x + 5) = 72
x² + 11x + 30 = 72
x² + 11x - 42 = 0
