A university's freshman class has 6200 students. 4836 of those students are majoring
WINSTONCH [101]

According to the solving 78% of the freshman class are Economics majors.

<h3>What does a percentage mean?</h3>

percentage, a relative figure signifying hundredths of any amount. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

<h3>Why is it called percent?</h3>

The word "percent" comes from the Latin adverb per centum, which means "by the hundred." In the sixteenth century, the Latin expression made its way into English. Later, it was shortened to % with a final period.

<h3>According to the given data:</h3>

It is given that the total number of students in freshman class = 6200

Total number of students majoring in Economics = 4836

Here, we are asked to find the percentage of the freshman class who are majoring in Economics.

Percent of students majoring Economics =  (Number of students majoring/ Economics  Total number of students) x 100

= \frac{4836}{6200} x 100

= 78%

According to the solving 78% of the freshman class are Economics majors.

PLS HELP. Find the first four terms of the recursive sequence defined by the following formula:
Gnoma [55]

Answer:

see explanation

Step-by-step explanation:

Given the recursive formula a_{n} = \frac{a_{n-1} }{4} and

a_{4} = 2 \frac{1}{4} = \frac{9}{4}, then

\frac{a_{3} }{4} = \frac{9}{4} ( multiply both sides by 4 )

a₃ = 4 × \frac{9}{4} = 9

\frac{a_{2} }{4} = 9 ( multiply both sides by 4 )

a₂ = 36

\frac{a_{1} }{4} = 36 ( multiply both sides by 4 )

a₁ = 144

The first 4 terms are

144, 36, 9, 2 \frac{1}{4}

Which of the following sets of angles sum to 180°?<br> picture included, please help.
eduard

Answer:

Choice 3

Step-by-step explanation:

add 63 and 64 which gives you 127. Then you subtract 180 and 127. This gives you 53. 63+53+64=180. Know that the angle is 180 degrees too so you don't even have to do math.
