Answer:
A=342 ft^2 (dark section)
A = 108 ft^2 (light section)
Step-by-step explanation:
18 x 25 = 450
9 x 12 = 108
450-108= 342
Answer:
The answer is C
Step-by-step explanation:
Answer: 7 inches.
Given that there was a quadrilateral ABCD and it was reflected over a line y
Hence preimage = ABCD and image = TURS
When reflected we have new position of A = T
new position of B =U
new position of C = R and
new position of D = S
By transformation properties, for reflection the scale factor is 1 and hence AB will have the same length as TU
Since AB = 7 inches, TU = 7 inches.
Note:
A reflection in the coordinate plane is just like a reflection in a mirror. Any point or shape can be reflected across the x-axis, the y-axis, or any other line, invisible or visible. This line, about which the object is reflected, is called the “line of symmetry.” Here we have line of symmetry as line y.
Answer:
Step-by-step explanation:
Confidence interval gives possible estimate (range of values) that could contain the population proportion. Confidence level does not not mean probability. It only tells how confident we are that that the population proportion lies within the confidence interval.
Since we were told that the confidence interval has a lower bound of 161.9 seconds and an upper bound of 165.5 seconds, therefore, the correct option for the given situation is
A. One can be 90% confident that the mean drive-through service time of this fast-food chain is between 161.9 seconds and 165.5 seconds.
Answer:
C(n) = 122 * 2^n
Explanation:
We are given that:
Each day, the number of likes increases two times compared to the previous day. This means that we can write the function as follows:
C(n) = 2*C(n-1)
We are given that:
C(0) = 122 likes (initial value)
Therefore, our function would become:
C(n) = 122 * 2^n
Now, let's test this function:
C(0) = 122 * 2^0= 122
C(1) = 122 * 2^1 = 244 (this is twice c(0))
C(2) = 122 * 2^2 = 488 (this is twice c(1))
.....and so on
Hope this helps :)
