Answer:
D. 4in, 12in
Step-by-step explanation:
Area of triangle = 24in²
Unknown:
Base and height of the triangle = ?
Solution:
The area of a triangle =
x base x height
From the problem,
base =
x height
let the base = b
height = h
b =
h
h = 3b
Input into the formula of area;
24 =
x b x 3b
Mulitply through by 2;
48 = 3b²
b² = 16
b = √16 = 4
So, h = 3b= 3 x 4 = 12in
The answer is two hundred thirty four.
Just around the 15 and 3. So it would be
(15-3)x4+9=57
This is because (15-3)= 12
12x4=48
48+9= 57
Question 11 is C and also question 2 is A
Answer:
d. 0.133
Step-by-step explanation:
-Standard error is calculated using the formula:

#We substitute the given values in the formula to solve for E:

Hence, the standard error is 0.133 and the correct option is d
