Find the angle measures given the figure is a rhombus.

WITCHER [35]

Answer:

1 = 90°, 2 = 66°

Step-by-step explanation:

Since the diagonals of a rhombus are perpendicular, ∠1 = 90°. Using the Exterior Angles Theorem (exterior angle = sum of remote interior angles, we see that ∠2 = 90 - 24 = 66°.

A researcher wishes to estimate, with 9999% confidence, the population proportion of adults who think Congress is doing a goo

jok3333 [9.3K]

Answer:

a: 1037 is the minimum sample size needed

b: 712 is the minimum sample size needed

Step-by-step explanation:

We need to use the formula for minimum sample size of a proportion when a sample proportion is known.

The level of confidence is 99%, which has a corresponding z-value of 2.575.

We know the desired error is 4%, or 0.04.

Part a: We have no prior estimate. See attached photo for calculation

Part b:

We know p-hat = 0.22. Therefore q-hat = 1 - 0.22 = 0.78

See the attached photo for the calculation of the minimum sample size
