Answer:
Step-by-step explanation:
This parabola is a horizontal one.
In the more familiar case, vertical parabolas, the applicable equation is:
y - k = a(x - h)^2, where (h, k) is the vertex and 'a' has to do with vertical compression or stretching.
For the horizontal parabola, we adapt the above formula to:
x - h = b(y - k)^2
substituting -17 for x and 2 for k:
x + 17 = b(y - 2)^2
Because the parabola opens to the left, b must be negative. One of many examples would be:
x + 17 = -2(y - 2)^2, where the choice of 'b' is arbitrary.
Answer:
The sample proportion of successful procedures is 0.962.
Step-by-step explanation:
The sample proportion of successful procedures is the number of successfiç procedures divided by the total number of procedures.
In this problem:
158 procedures, of which 152 were successful. So
p = 152/158 = 0.962
The sample proportion of successful procedures is 0.962.
Answer: 253.5
Step-by-step explanation:
Answer:
90%
Step-by-step explanation:
You can make the votes simple by dividing 8 on 80 and 72
80 becomes 10
72 becomes 9
You can do this because we done the same thing to both sides
now it is Yoko got 9 out of 10 and we know 9 out of 10 is 9/10 or 90/100 which mean Yoko got 90% of the club members vote
<u>Answer</u>
59°
<u>Explanation</u>
There are 2 parallel line and one transverse.
Angles in a straight line add up to 180°
∴ 180 - (2a + 3) = 180 - 2a -3
= 177 - 2a
The angle (177 - 2a) corresponds to angle a in the diagram. The two corresponding angles are equal.
∴ 177 - 2a = a
177 = a + 2a
3a = 177
a = 177/3
= 59°
