Answer:
Step-by-step explanation:
Z = (x-µ)/(s/√n)=(98.5-98.2)/(0.62/√19) = 2.11
left tail p-value = 0.9826
so 98.26% are lower.
−10x + 1 + 7x = 37
combine like terms
-3x + 1 = 37
subtract 1 from both sides
-3x = 36
divide both sides by (-3)
x = - 12
Answer
x = - 12
Answer:
I'm not sure what your asking, but, no, all rectangles are parallelograms.
I found this over the internet, and I hope it helps you understand why a rectangle is always a parallelogram, but a parallelogram is not always a rectangle:
It is true that every rectangle is a parallelogram, but it is not true that every parallelogram is not a rectangle. For instance, take a square. It's a parallelogram — it is a quadrilateral with two pairs of parallel faces. But it is also a rectangle — it is a quadrilateral with four right angles.

Answer:
-15
Step-by-step explanation:
so to start you must distribute negative two times negative two equals positive four,
so now your equation looks like this,
2^2 +4+4-3^3
then you need to do the exponents,
2 x 2 = 4
3 x 3 x 3 =27
now it looks like this
4+4+4-27
12 - 27
-15
Hope that helps!
