Answer:
The z-score of a beetle with a length of 2.38 centimeters is 2.4
Step-by-step explanation:
As we know,
z = (x - µ)/σ
x is the length of the beetle species.
µ is the mean length
σ is the standard deviation
Substituting the given values in above equation, we get
z = (2.38 - 1.9)/0.2
z = 0.48/0.2
z = 2.4
ab + a + 4b+4 = a(b+1) + 4(b+1) = (b +1)(a + 4)
It would cost a total of $120. dont forget your dollar sign
Answer:
A = (2x² + 4x + 1) (8 − x)
A = -2x³ + 12x² + 31x + 8
Step-by-step explanation:
W = 2x² + 4x + 1
L = 8 − x
Area is width times length.
A = (2x² + 4x + 1) (8 − x)
If you wish, you can simplify with distribution.
A = 8 (2x² + 4x + 1) − x (2x² + 4x + 1)
A = 16x² + 32x + 8 − 2x³ − 4x² − x
A = -2x³ + 12x² + 31x + 8
Answer:
Store C, Store B, Store A
Step-by-step explanation:
If you were to buy 1 pound of pears at Store A, It would be $1.29
If you were to buy 1 pound of pears at Store B, It would be $1.00
If you were to buy 1 pound of pears at Store C, It would be $0.89
