<u>Given</u>:

Given that the list of students' scores on a quiz.

The list of students' scores are 5, 12 ,7, 15, 20, 14, 7

We need to determine the mode of these scores.

<u>Mode</u>:

The mode of the set of data is the number that occurs most often in the given set of numbers.

Thus, from the data, the number that occurs most often is 7.

The number 7 occurs twice in the given set of data which is the maximum number of occurrence by any other number in the given set of data.

Hence, Mode = 7

Therefore, the mode of these scores is 7.

joy added 26 new contacts to her phone list. She now has a total of 100 contacts. Let c represent how many contacts joy had on h
Nesterboy [21]

Answer: 26 + c = 100

Step-by-step explanation: To find what c equals, we must flip the solution around and subtract it. When we take 100 - 26, we get 74. Therefore, c = 74. I hope this helped! :)

Sean made a ribbon that was 3 1/6 inches long. Fran made one that was 1 5/6 inches long.How much longer was Sean's ribbon than F
brilliants [131]
Let's rewrite the mathematical expressions:
 3 1/6 = 3.166666667
 1 5/6 = 1.833333333
 Subtracting both expressions we have:
 3.166666667- 1.833333333 = 1.727272727
 Answer:
 
Sean's ribbon is 1.727272727 in long than Fran's

The Hudson Bay tides vary between 3 feet and 9 feet. The tide is at its lowest point when time (t) is 0 and completes a full cyc
BaLLatris [955]

Answer:

y(t)= 6-3cos(\dfrac{2\pi}{14}t )

Step-by-step explanation:

The function that could model this periodic phenomenon will be of the form

y(t) = y_0+Acos(wt)

The tide varies between 3ft and 9ft, which means its amplitude A is

A =\dfrac{(9-3)ft}{2} \\\\\boxed{A = 3ft}

and its midline y_0 is

y_o=3+3 \\\\\boxed{y_o= 6ft}.

Furthermore, since at t=0 the tide is at its lowest ( 3 feet ), we know that the trigonometric function we must use is -cos(\omega t).

The period of the full cycle is 14 hours, which means

\omega t =2\pi

\omega (t+14)= 4\pi

giving us

\boxed{\omega = \dfrac{2\pi}{14}.}

With all of the values of the variables in place, the function modeling the situation now becomes

\boxed{y(t)= 6-3cos(\dfrac{2\pi}{14}t ).}
