Answer:
option a
Step-by-step explanation:
given that at a large Midwestern college, 4 % 4% of the students are Hispanic.
A random sample of 20 students from the college is selected.
We have each student is independent of the other to be hispanic
p = success = being hispanic = 0.04 while
q = failure = being non hispanic = 0.96
X - no of hispanics is thus binomial with p = 0.04 and n =20 (sample size)
Since X is binomial
Var(x) = npq = 0.768
Std dev (x) = Square root of variance = 
rounded off it gives 0.88
So option a is right
Answer: If you need to find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem if you know the length of the other two sides. Square the length of the 2 sides, called a and b, then add them together. Take the square root of the result to get the hypotenuse
There is a global standard for connecting high-definition electronics and PC products. HDMI technology helps in providing people with the highest signal possible to meet the current needs of HD entertainment systems with only a single cable that it uses for transmission. Currently, every new digital TV must have at least one HDMI port and the the connectivity has been standardized on one range of electronic products. 2x, 3x, 4x is the number of HDMI ports. This implies that 4x has more ports than 3x.
Your y-intercept would be (0,-15) and your x-intercept would be (-60,0)
65
1. you work in the parentheses and multiply 2.8 by 5 which is 14
2. you divide 14 by 7 which is 2
3. you follow PEMDAS and multiply 26 by what is in the parentheses (2) which is 52
4. you add 13 with 52 which is 65
hope this helped!!
