Answer:
a) Z for northern region = 1 , Z for southern region = -1.2
b) Southern region
Step-by-step explanation:
a) Z = (x – mean)/standard deviation
Le x be weight for birds
For the northern region
Z = (13 – 10)/3
Z = 1
For the southern region
Z = (13 – 16)/2.5
Z = -1.2
b) to find in what region is more likely to find a bird with 13 ounces, we calculate the probability for each z value
For the northern region
P (x>13) = P(z > 1)
Then we use the z table to find the area under the curve.
P (x>13) = 0.1587
For the southern region
P (x>13) = P(z > 1.2)
Then we use the z table to find the area under the curve.
P (x>13) = 0.8849
Is it more likely that a bird with a weight greater than 13 ounces lives in the southern region

$50.00-$32.74=$17.26
Answer: x=2.5
Step-by-step explanation:
First we need to set up and equation
10= 60 - 20x
where x is the amount the cookies cost
subtract 60 from both sides
-50=- 20x
now divide each side by 20 so hat we can isolate the x
-50/-20= x
x= 2.5
now to check just multiply it by 20 then subtract from 60.
2.5 x 10= 50
60-50=10

Answer:
C no es equivalente a 6/11.
Step-by-step explanation:
24/42 no es equivalente a 6/11 porque, cuando se simplifica, no es igual a este número. Si usamos el número 6 para simplificar, la respuesta a 24/42 sería 4/7, que no es igual a 6/11.
