I don’t understand that language
Let x be the population distribution.
p(25 ≤ x ≤ 33) = p((25 - 29)/4 ≤ z ≤ (33 - 29)/4) = p(-1 ≤ z ≤ 1) = p(z ≤ 1) - p(z ≤ -1) = p(z ≤ 1) - [1 - p(z ≤ 1)] = 2p(z ≤ 1) - 1 = 2(0.84134) - 1 = 0.68268 = 68%
p(21 ≤ x ≤ 25) = p((21 - 29)/4 ≤ z ≤ (25 - 29)/4) = p(-2 ≤ z ≤ -1) = p(z ≤ -1) - p(z ≤ -2) = [1 - p(z ≤ 1)] - [1 - p(z ≤ 2)] = p(z ≤ 2) - p(z ≤ 1) = 0.97725 - 0.84134 = 0.13591 = 13.5%
Answer:
david 100% increase
Step-by-step explanation:
b/c if lets say it was $2 before the price was doubled after it waas doubled it would be $4 if it had been risen by 50% it would have been $3 but if it waas risen by 100% it would be $4
Answer:
Equilateral triangle
Step-by-step explanation:
Sum of all the angles jn a triangle is 180°
Therefore, 180/60=3(no.of sides)
You can see that triangle has 3 sides.
Therefore you can conclude that triangle is the answer. Pls note that if only 1 triangle is mentioned in the question then this will be your answer like thw one above. But if the question is which triangle has all of its angles has 60° then your answer will be equilateral triangle. You can also make a note that sum of all the angles of a triangle is 60°. I think i typed a lot for the explanation although i dont like teaching much. But still i hope this will be helpul.
