You measure 20 turtles' weights, and find they have a mean weight of 45 ounces. Assume the population standard deviation is 11.5
Naily [24]

Answer: the maximal margin of error associated with a 90% confidence interval for the true population mean turtle weight = 4.23

Step-by-step explanation:

Formula for margin of error : E=\dfrac{z^*\times (Population\ standard\ deviation)}{\sqrt{Sample\ size}}

, where z* = Critical z-value.

Given: population standard deviation = 11.5 ounces

Sample size = 20

Z value for 90% confidence level = 1.645

margin of error (E) = \dfrac{1.645\times11.5}{\sqrt{20}}

\approx4.23

Hence, the maximal margin of error associated with a 90% confidence interval for the true population mean turtle weight = 4.23

What is the product of 16x48?
Elis [28]
768 because 6x8 = 48 the 8 drop Down to the answer and the 4 on top of 1 and multiply 1x8= 8+1 =9 so the 9 drop down to the answer. Now that is fake because you need to multiply 4x6 and 4x1 so 4x6 is 24 below the 8 add a 0 and go 1 move to the left and put 4 and 2 on top of 1 now 4x1 is 4+1 is 5 and put 5 on the left of 4 and the final step is add 98+540=768 so 768 is your real answer.

OverLord2011 [107]

Answer:

A. D and E are similar but not congruent.

Step by step explanation :

The side lengths of D are 3 units and 1 unit.  The side lengths of E are 2 units and 6 units.  The sides are proportional, but are not congruent; this means that the quadrilaterals are similar but not congruent.  Choice A is true and choice C is false.

The side lengths of E are 2 units and 6 units.  The side lengths of F are 3 units and 1 unit.  The sides are proportional, but are not congruent; this means that the quadrilaterals are similar but not congruent.  Choice B is false.

The side lengths of D are 3 units and 1 unit.  The side lengths of F are 3 units and 1 unit.  The sides are congruent; this means that the quadrilaterals are congruent.  Choice D is false.
