give some Parameters so that we can solve
Answer:
B. 4
Step-by-step explanation:
The degree of the polynomial (the exponent of the highest term) is the total number of roots (including imaginary roots).
The degree of this polynomial is 4, so there are 4 roots.
Answer:
36.88% probability that her pulse rate is between 69 beats per minute and 81 beats per minute.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Find the probability that her pulse rate is between 69 beats per minute and 81 beats per minute.
This is the pvalue of Z when X = 81 subtracted by the pvalue of Z when X = 69.
X = 81
has a pvalue of 0.6844
X = 69
has a pvalue of 0.3156
0.6844 - 0.3156 = 0.3688
36.88% probability that her pulse rate is between 69 beats per minute and 81 beats per minute.
Answer: $585.60
Step-by-step explanation:
The number of years that would have passed is;
= 2016 - 1626
= 390 years
Using simple interest, the investment will be worth;
= Principal * ( 1 + rate * number of years)
= 24 * (1 + 0.06* 390)
= $585.60
