Step-by-step explanation:
From the question we are told that
The proportion that own a cell phone is 
The sample size is n = 15
Generally the appropriate distribution for X is mathematically represented as

So

Generally the number students that own a cell phone in a simple random sample of 15 students is mathematically represented as



Generally the standard deviation of the number of students who own a cell phone in a simple random sample of 15 students is mathematically represented as

Where q is mathematically evaluated as





Generally the probability that all students in a simple random sample of 15 students own a cell phone is mathematically represented as

From the combination calculator is 


Answer:
The coefficient is 9
Step-by-step explanation:
(a)(b)(c)+(a)(2c)(2a)+(2b)(b)(c)+(2b)(2c)(2a)
abc+4ca^2+2cb^2+8abc
9abc+4ca^2+2cb^2

Step-by-step explanation:
Answer:
240 houses
Step-by-step explanation:
Given that:
Number of streets = 4
Length of each street = 3/4 miles long
Street is divided into lots with one house built per lot
1 mile = 5289 feets
3/4 miles = (3/4) * 5280 = 3960 feets
Hence, street is 3960 feets long
Since each lot must have at least 65 feet frontage along the street:
Number of lots per street :
Length of street / frontage length
3960 ft / 65 ft = 60.92
Hence, maximum number of lots per street = 60 lots per street
Maximum number of houses in New neighborhoods :
Number of lots per street × number of streets
= 60 × 4
= 240 houses
Answer and Step-by-step explanation:
To solve, we would multiply by the reciprocal of the portion Jada has read, and multiply that number to 75.
The reciprocal means the the value, but flipped, so
will become
.
Now we do 75 times
