Step-by-step explanation:just guess
Answer:
See below.
Step-by-step explanation:
Rectangle PQRS is the shape in neon green. The area is b*h with base 7 and height 2. The area is 14.
Square ABCD is the shape in black. The area is s^2 with side 4. The area is 16.
Triangle EFG is the shape in purple. The area is 1/2 b*h with base 8 and height 4. The area is 1/2 *8*4 = 16.
Triangle UVW is the shape in pink. The area is 1/2 b*h with base 7 and height 4. The area is 1/2 * 7*4 = 14.
Answer: 0.7619
Step-by-step explanation:
Given : Mean :
Standard deviation :
Sample size :
We assume that the variable is normally distributed.
The value of z-score is given by :-
a) For x= 46.9 years
The p-value :
Hence, the probability that the average age of those doctors is less than 46.9 years =0.7619
Answer:
(3x^2+1)*(7x-2)
Step-by-step explanation:
(1): "x2" was replaced by "x^2". 1 more similar replacement(s).
STEP
1
:
Equation at the end of step 1
(((21 • (x3)) - (2•3x2)) + 7x) - 2
STEP
2
:
Equation at the end of step
2
:
(((3•7x3) - (2•3x2)) + 7x) - 2
STEP
3
:
Checking for a perfect cube
3.1 21x3-6x2+7x-2 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 21x3-6x2+7x-2
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 7x-2
Group 2: 21x3-6x2
Pull out from each group separately :
Group 1: (7x-2) • (1)
Group 2: (7x-2) • (3x2)
-------------------
Add up the two groups :
(7x-2) • (3x2+1)
