Answer:
0.16
Step-by-step explanation:
81 is 1 standard deviation below the mean. According to the empirical rule, 68% of data lies within 1 standard deviation of the mean; here the equivalent statement would be that half of that, or 34%, lies within 1 standard deviation below the mean. Half of the area under the standard normal curve, less this 0.34, is the probability that the random variable is below 1 standard deviation beneath the mean. That comes to 0.16.
On a calculator, you might enter the command normalcdf(-100,81,85,4); on my old TI-83 Plus I get 0.1587, which rounds off to 0.16.
B and C
3^3 = 27
the cubed root of 27 is 3
If you would like to know the height of the tree 10 years from now, you can calculate this using the following steps:
h ... the height of the tree 10 years from now
h = 30 feet + 5 feet = 35 feet
The correct result would be D. 35 feet.
Answer:22:2x10x10x10x10x10x10x10x10x10x10... 23:3.4x10 divided by 2.... 24:1.5x10 divided by 9...... 25:5.9x10x10x10x10x10x10x10x10x10x10.... 26: 4.8 x 10 divided by 3..... 27: 6.25x10x10x10x10x10.
Step-by-step explanation:I divide because on some of them it's a negative power so instead of multiplying I'll divide. Hope this helps
Answer:
The maximum number of turns is 3
Step-by-step explanation:
The given function is
The degree of this polynomial is 4.
If the degree of a given polynomial is n, then the polynomial has at least n-1 turns.
Therefore the number of turns of this 4th degree polynomial is at least 3.
