Answer:
x = 12
Step-by-step explanation:
You can use power of a point to solve this problem in the scenario where two secants intersect in the exterior of a circle. You get the equation:
(x + 5 + 7)(7) = (x + 1 + 8)(8)
You can simplify to get:
(x + 12)(7) = (x + 9)(8)
7x + 84 = 8x + 72
84 = x + 72
x = 12
Answer:
The length of the necklace is 12.20 foot
Step-by-step explanation:
Given as :
The height of the ice cream cone to the ground = h = 10 foot
The angle make by the necklace of the ice cream cone = 55°
Let The length of the necklace = L foot
<u>Now, from figure </u>
Height = BC = h foot
The length of the necklace = L = AC
So, Sin angle =
Or, Sin 55° =
Or, 0.8191 =
Or, 0.8191 =
Or, L =
∴ L = 12.20 foot
So, The length of necklace = L = 12.20 foot
Hence The length of the necklace is 12.20 foot Answer
The mode is 4 and 9 (if two different numbers appear twice then they are both the mode)
The median is 4 as it is the middle number (put the numbers in order to find this out and cancel each number out from both sides, if there are two numbers left add them both and divide by two)
The mean is 4.3 because if you add them all up and divide by how many there are then you will get 4.285. Round this to one decimal point and 4.3 should be the answer. Mean is another word for average
