Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Number of times the spinner spun = 75
Outcomes Frequency
A 20
B 11
C 14
D 30
We need to find the experimental probability of spinning an "A" :
so, Probability of spinning an A is given by
Probability of getting an A is 0.27.
Hence, Option 'c' is correct
please mark me brainiest i am almost an expert!!
Answer:
289 units
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = πd ( d is the diameter )
Here C = 907.46 , thus
907.46 = πd ( divide both sides by π )
d = ≈ 289 units ( nearest whole number )
Answer:
<h2>a) (5, 11)</h2><h2>b) r = 9</h2><h2>c) (-4, 11)</h2>
Step-by-step explanation:
The equation of a circle in standard form:
(h, k) - center
r - radius
We have the equation:
Therefore
a) h = 5, k = 11 → the center (5, 11)
b) r² = 81 → r = √81 = 9 - radius
c) We choose any value of x, but one which h - r ≤ x ≤ h + r
5 - 9 = -4
5 + 9 = 14
-4 ≤ x ≤ 14
Let x = -4. Put to the equation and solve for y:
<em>subtract 81 from both sides</em>
<em>add 11 to both sides</em>
(-4, 11)
