Answer: 35 dogs
Step-by-step explanation:
Ratio of dogs to cats in first week of January
= 49 : 28
Ratio of dogs to cats in last week of January
= ? : 20
Let the unknown number of dogs for last week be Z
Thus, 49/28 = Z/20
To get the value of Z, cross multiply
49 x 20 = 28 x Z
980 = 28Z
Divide both sides by 28
980Z/28 = 28/28
Z = 35
Thus, there were 35 dogs in the animal shelter during the last week
The probability of randomly picking one of those dishes is <span><span>8</span></span><span> out of </span><span><span>20</span></span><span>, or 8/20. We can simplify that down to 2/5. </span>
Answer:
Step-by-step explanation:
i) 1
ii) see attached
iii) as x goes from 0 to 2, y decreases parabolically from 1 to an acme at -3
iv) y = (x - 2)² - 3
v) -3 < t < 1
if t < -3 no intersection occurs between y = t and y = (x - 2)² - 3
if t = -3, y = t intersects the curve at only one point, (2, -3)
if -3 < t < 1 there exist two intersecting points with positive x values
if t = 1 there exist only one positive x value intersection as the other is at (0, 1) and 0 is neither positive nor negative.
if t > 1 there is one positive x value intersection and one negative x value intersection.
