Answer:
Option C: n = 32; p^ = 0.4
Step-by-step explanation:
The normal curve can be used in this case if; np ≥ 10 or n(1 - p) ≥ 10
A) For n = 28 and p = 0.3;
np = 28 × 0.3 = 8.4 < 10
Thus, it can't be used.
B) For n = 28 and p = 0.9;
np = 28 × 0.9 = 25.2 > 10 Ok
n(1 - p) = 28(1 - 0.9) = 2.8 Not Ok
Thus, it can't be used
C) For n = 32 and p = 0.4
np = 32 × 0.4 = 12.8 > 10 Ok
n(1 - p) = 32(1 - 0.4) = 19.2 > 10 Ok
Thus, it can be used
D) For n = 32 and p = 0.2
np = 32 × 0.2 = 6.4 < 10 Not Ok
Thus it can't be used.
Answer:
I'm thinking B
Step-by-step explanation:
The perimeter of a square is straight and linear is straight. Not 100% sure but its your best bet.
To figure out the answer, you need to find the perimeter. To do this you know (93*2)+(63*2). Your answer is 312 ft.
2 ft of crepe paper this is not answer I'm dumb but love to help
So firstly, we have to factor out the GCF, or greatest common factor, of these terms. To find the GCF, list the factors of each term and the greatest one they share is their GCF. In this case, the GCF is 3x:
Next, what's inside the parentheses is considered a perfect square. Using this format of 
, we can factor it as such:
<u>The factors of this expression are 3x, x + 3, and x + 3.</u>
