A box contains
1 answer:
The probability of picking a hazelnut chocolate is 1/5 and the number of hazelnut chocolates in the box is 1
<h3>How to determine the probability</h3>Note that the ratios = 5:4:2:3
toffee: coffee: orange: mint chocolates = 5:4:2:3:1
Total ratio = 15
Probability of picking a hazelnut chocolate = ratio of hazelnut chocolates/ total ratio
Probability of picking a hazelnut chocolate =
The number of hazelnut chocolates in the box is gotten from the ratio which is 1
Therefore, the probability of picking a hazelnut chocolate is 1/5 and the number of hazelnut chocolates in the box is 1

Answer:
(a)
(b) 7.5ft above the low tide.
Step-by-step explanation:
(a) To find the function that computes the height of the tide, you need to select the form of the sinusoidal function. For example, use the form:
Where A is the amplitude, B the frequency, C the phase shift and D the vertical shift.
The amplitude is half the distance between the highest and the lowest tide:
The frequency is related to the period T by:
The period is 12 hours, then
The high tide is at 1:00 a.m. and 1:00 p.m. , this is the moment when , if
then
must be equal to
when
:
The vertical shift is the sum of the lowest value, the height of the low tide () and the amplitude:
The function is:
Because the function must be the height above low tide height, subtract this heigh from the function:
(b) Use x=11 in the function
above the low tide.
