MARKING BRAINIEST If cos(w°) = sin(z°), which of the following statements is true? triangle ABD and ECD in which angle D measures 90 degrees, angle A equals w degrees, angle B equals x degrees, angle E equals y degrees, and angle C equals z degrees
z = x and ΔABD ≅ ΔECD
w = z and ΔABD ≅ ΔECD
z = x and ΔABD ~ ΔECD
w = z and ΔABD ~ ΔECD

7.(03.01 lc)which set represents the range of the function shown? {(-1, 5), (2,8), (5, 3), 13, -4)} (5 points){-1, 2, 5, 13){(5, -1), (8, 2), (3,5), (-4, 13)){-4, 3, 5, 8}{-4, -1, 2, 3, 5, 5, 8, 13}

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?

The poll report includes a table titled, “americans using cash now versus five years ago, by age.” the age intervals are not equal. why do you think the gallup organization chose the age intervals of 23–34, 35–54, and 55+ to display these results?
