Refer to the accompanying data set and construct a 9090​% confidence interval estimate of the mean pulse rate of adult​ females;

then do the same for adult males. Compare the results. Loading... Click the icon to view the pulse rates for adult females and adult males. Construct a 90​% confidence interval of the mean pulse rate for adult females. 71.8 bpm < μ< 79.0 bpm Construct a 90​% confidence interval of the mean pulse rate for adult males. 63.3 bpm < μ 69.9 bpm. Compare the results.
A. The confidence intervals do not​ overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.
B. The confidence intervals do not​ overlap, so it appears that adult females have a significantly higher mean pulse rate than adult males.
C. The confidence intervals​ overlap, so it appears that adult males have a significantly higher mean pulse rate than adult females.
D. The confidence intervals​ overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.

Find the missing number so that the equation has infinitely many solutions.
Alex17521 [72]

equation has infinitely many solutions has the same number on both sides of the equal sign

-3x -21 + x + 5 = -20x -16

-2x -16 = -20x -16

so either you have -18x on the left or +18x in the right

Compare and Contrast: Two equations are listed below. Solve each equation and compare the solutions. Choose the statement that i
Allisa [31]
<span>The correct answer is option B. i.e. Both equation 1 and 2 have the same number of solutions. The equation 1 is |5x+6| = 41 By removing the modulus sign we get, 5x + 6 = 41 and 5x +6 = -41. Solving, 5x = 6 = 41 we get, 5x = 35 or x = 7. And, on solving 5x +6 = -41 we get, 5x = -47 or x = 9.4 Now. the second equation is |2x+13| = 28 By removing the modulus sign we get, 2x+ 13 = 28 and 2x +13 = -28. Solving, 2x = 28 -13 = 15 or x = 7.5 . And, on solving 2x +13 = -28 we get, 2x = -41 or x = -20.5.TH </span>

Whats 3/4 as a decimal
pentagon [3]
Since this is out of 4, you can think of 4 as being 1. Now each part of 4 needs to have an equal value so you need to split 1 into 4 equal values. So half of 1 is 0.5 and half of 0.5 is 0.25. So, each part of 4 has a value of 0.25.

1/4 = 0.25
2/4 = 0.50
3/4 = 0.75
