Answer: 37
Step-by-step explanation:
Given that:
Total number of beads on her necklace = 50
Percentage of blue beads = 26%
Therefore, number of blue beads :
Percentage number of blue beads × total number of beads on necklace
Number of Blue beads = 26% × 50
= 0.26 × 50 = 13
Number of Blue beads = 13
Therefore, number of beads that aren't blue :
Total number of beads - number of blue beads
50 - 13 = 37
Number of beads that aren't blue = 37
3 seconds
solve for when y is zero
0 = -16t^2 + 32t + 48
0 = -16(x^2-2x-3)
0 = -16(x-3)(x+2)
x = 3 or -2
-2 is extraneous because time is not negative in this instance so 3 seconds.

Answer:
99.7%
Step-by-step explanation:
Bell shaped curve by empirical rule is that if the standard deviation from the mean (left to right) is 1 deviation then about 68% of the data is in that range if it’s 2 standard deviations away then it’s 95% and 3 deviations away is 99.7%
142-100=42=3(14)
100-58=42=3(14)
Therefore the data is three standard deviations from the mean and this there is 99.7% of the data in this range.
