Based on the limited amount of available student parking spaces on the GSU campus, students are being encouraged to ride their b

ikes (when appropriate). The administration conducted a survey to determine the proportion of students who ride a bike to campus. Of the 120 students surveyed 5 ride a bike to campus. Which of the following is a reason the administration should not calculate a confidence interval to estimate the proportion of all students who ride a bike to campus? Check all that apply. The sample needs to be random but we don’t know if it is. The actual count of bike riders is too small. The actual count of those who do not ride a bike to campus is too small. n * ^ p is not greater than 10 . n *( 1 − ^ p )is not greater than 10 .

The diameter of a human red blood cell is 0.000009 m. The diameter of a cold virus is 0.00000003 m Approximately how many times
krek1111 [17]

Answer:

D. 3*10^2

Step-by-step explanation:

Given the diameter of human red blood cell =  0.000009 m

diameter of a cold virus = 0.00000003 m

To know how many times as large is the diameter of a red blood cell as the diameter of a cold virus, we will take the ratio of the diameter of human red blood cell to that of a cold virus as shown;

diameter of human red blood cell/diameter of a cold virus = 0.000009 m/0.00000003 m

= 9*10^-6/3*10^-8

= 9/3 * 10^-6-(-8)

= 3 * 10^(-6+8)

= 3*10^2

Hence the diameter of a red blood cell is 3*10^2 larger than that of the cold virus

A family travels, by plane, five hundred miles from their city to a beach town. Then they take a taxi from the airport to the ho
Juliette [100K]
To work out how many miles the distance from the airport to the beach, we can use 1km ≈ 0.62 miles
To get from 20km from 1km, we multiply by 20
If we do the same to 0.62
0.62 x 20 = 12.4 miles
Next step is to add this on to the 500 miles they travelled by plane
500 + 12.4 = 512.4 miles
