Step-by-step explanation:
Prime numbers are numbers that only have two divisors of 1 and itself.
PRIME NUMBERS INCLUDED BETWEEN 40 AND 50 =
41.43.47.
41 + 43 + 47 = 131
Answer:
x=9/20 or x=0.45
Step-by-step explanation:
You can use F.O.I.L. for this, which if you don't know stands for first outer inner last, so multiply the first in each parentheses, then the outer, then the inner, then the last. yours would be 3*5+3*√7+(-√7)*5+(-√7)*√7 => 15+3√7-5√7-7 => 8-2√7
Final answer:
8-2√7

Answer:
Option b
Step-by-step explanation:
Given that For a particular course, the pass rate for the 16-week format is 59%. A team of faculty examine student data from 40 randomly selected accelerated classes and determine that the pass rate is 78%.
we have to find whether taking a class in a short-term format (8 weeks instead of 16 weeks) increase a student’s likelihood of passing the course
Since pass rate for 16 weeks is 59% we check whether for 8 weeks is more than this.
So correct null and alternative hypotheses for this research question
would be:
b.H0: p = 0.59; Ha: p > 0.59
Option b is right.
When the sign is < or > (less than/greater than), you graph an open circle.
When the sign is ≤ or ≥ (less than/greater than <u>or equal to)</u>, you graph a closed circle.
The 4th option is your answer since the sign is ≥
