A kiddie pool holds miniature plastic ducks in different colors. Sophia randomly picks up a duck and then replaces it. She repea

ts this process 100 times. The table shows the results of her experiment.
What is the relative frequency of choosing a red duck? What color of duck is there likely to be the most of in the pool?

A. The relative frequency is 0.3. It is likely that most ducks are blue.
B. The relative frequency is 0.2. It is likely that most ducks are yellow.
C. The relative frequency is 0.3. It is likely that most ducks are yellow.
D. The relative frequency is 0.2. It is likely that most ducks are green.

The answer is C because there are 30 red ducks and if you put that in a decimal it is 0.3 and if there are more yellow ducks out of all of them

Greeley [361]

Answer:

(x_1,y_1) = (1,5840)

(x_2,y_2) = (2,13090)

y = 1812.5x + 4027.5

y_0 = 4027.5 --- y intercept

Step-by-step explanation:

Given:

x = weeks; y = copies

The right parameters are:

After 1 week, 5840 copies were downloaded

After 5 weeks, 13090 copies were downloaded

So, the (x,y) forms are:

(x_1,y_1) = (1,5840)

(x_2,y_2) = (5,13090)

Next, we calculate the slope (m) using:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{13090 - 5840}{5 - 1}

m = \frac{7250}{4}

m = 1812.5

The equation is then calculated using:

y = m(x - x_1) + y_1

y = 1812.5(x - 1) + 5840

y = 1812.5x - 1812.5 + 5840

y = 1812.5x + 4027.5

To calculate the y intercept, substitute 0 for x

y_0 = 1812.5*0 + 4027.5

y_0 = 0 + 4027.5

y_0 = 4027.5

Based on FAA estimates the average age of the fleets of the 10 largest U.S. commercial passenger carriers is 13.4 years with a s
Aliun [14]

Answer : 0.0129

Step-by-step explanation:

Given : Based on FAA estimates the average age of the fleets of the 10 largest U.S. commercial passenger carriers is \mu=13.4 years and standard deviation is \sigma=1.7 years.

Sample size : n=40

Let X be the random variable that represents the age of fleets.

We assume that the ages of the fleets of the 10 largest U.S. commercial passenger carriers are normally distributed.

For z-score,

z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}

For x=14

z=\dfrac{14-13.4}{\dfrac{1.7}{\sqrt{40}}}\approx2.23

By using the standard normal distribution table , the probability that the average age of these 40 airplanes is at least 14 years old will be :-

P(x\geq 14)=P(z\geq2.23)\\\\=1-P(z

Hence, the required probability = 0.0129

PLEASE HELP
xeze [42]

Answer:

-4

Step-by-step explanation:

So we are given the expression: | y - x | + y - 1, and we have our values for (x,y): (-3,-6).

So, we can just start plugging things in and simplifying, so:

| -6 + 3 | - 6 - 1 = | -3 | -7

                       = 3 - 7

                       = -4

ryan rides his bicycle 5 miles in 3/4 hour. how many miles can he ride at the same rate in 1 hour? (in fractions)​
stepladder [879]

Answer:

20/3

Step-by-step explanation:

If Ryan rides his bike 5 miles in 3/4 of an hour, then he rides 5/3 miles in 1/4 of a hour (divide both by 3). To get to a full hour from 1/4, you need to multiply it by 4. You must do the same for 5/3. 5/3*4 is equal to 20/3.
