According to a survey by a restaurateur's magazine on favorite types of food, 45% of their
readers chose Italian, 25% Mexican, 15% American, 10% French, and 5% Ethnic.

Answers

Any number chosen randomly without any design or process is called a random number.

Italian, = 9/20

Mexican, = 5/20

American, = 3/20

French, = 2/20

and

Ethnic, 1/20

Suppose we choose   as the random number then according to the given data

Italian,45% = 45/100 = 9/20

Mexican, 25% =25/100= 1/4× 5/5= 5/20

American, 15% = 15/100= 3/20

French, 10% = 10/100 = 1/10 = 2/20

and

Ethnic, 5% = 5/100 = 1/20

If we add the fractions it sums up to 1 which shows their true probability.

The sum of probability can never be greater than 1 . It is always equal to 1.

Yael worked out at a gym for 3 hours. Her workout consisted of stretching for 21
minutes, jogging for 39 minutes, and lifting weights for the remaining amount of
time. What percentage of Yael's workout was spent lifting weights?

Answers

21 + 39 = 60 minutes ( 1 hour)

So for the remaining time she lifted weights for about 2 hours.

3 hours = 180 minutes

180 - 60 = 120

About 66% of the remaining time Yael used to lift weights.

To be accurate 66.6% ( the last 6 repeating a infinite amount of time aka it doesnt end)

What are Decimal?

A group of numbers between integers on a number line are known as decimals. They are merely an additional mathematical representation of fractions. Decimals allow us to express measurable quantities like length, weight, distance, money, etc. with greater accuracy. Integers, also known as whole numbers, are represented to the left of the decimal point, while decimal fractions are represented to the right of the decimal point.

Fit Data to a line

When using empirical data ( data and information collected by scientists in an experiment ), sometimes, that data will not form a perfect line on a graph. when this happens, the line that is created using a linear regression is known as the " line of best fit " the following speed data was collected from a car moving with a constant acceleration.

1 - what is the line of best fit for this data? perform a linear regression on this table to find the equation .


2 - based on your equation, what was the car's approximate initial velocity (at time = 0) ?

3 - if the car continued at the same acceleration (meaning the slope of the line does not change), how fast would it be going in 15 seconds ? ​

Answers

Using a linear regression calculator, the best fit line, initial velocity and the velocity of the car after 15 seconds is :

y = 3.64x + 5.7 Initial Velocity = 5.7 m/s Velocity after 15 seconds = 60.3 m/s

Using technology, the linear regression equation obtained by fitting the data is :

y = 3.64x + 5.7

x = times(seconds) ; y = velocity(m/s)

The approximate velocity at time = 0 ; x = 0 :

y = 3.64(0) + 5.7

y = 0 + 5.7

y = 5.7 m/s

3.) Velocity after 15 seconds :

At time, x = 15 seconds

y = 3.64(15) + 5.7

y = 60.3 m/s

Therefore, the velocity of the car after 15 seconds is 60.3 m/s
