Answer:
15 yd²
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A = 
bh ( b is the base and h the perpendicular height )
here b = 10 and h = 3, hence
A = × 10 × 3 = 15 yd²
It’s one because all sides are one
Answer:
nothing
Step-by-step explanation:
you do not have to do anything given these seven sample means. This is because the sample means are all within the upper and the lower control limits. the plots are randomized and they do not form any patterns. This process is still in control so you do not really have to do anything. This answers the question.
Basically you set it up 43/8+26/5. When you do that multiply 5 by 8 so the donominiter will be 40. Then multiply 5 by 43 which is 215 and 8 by 26 which is 208 so now you have the same donominiter... 215/40+208/40 add 215 to 208 that's 423/40 then you see how many times does 40 divide into 423 that's 10 and then you had 23 left so put 10 23/4 .if it was a case like 10 3/12 you could simplify it and that would be 10 1/4 ...
Negative + negative cancel each out
so -11 + -5 = 16
