Is the solution to this quadratic equation rational or irrational? Why?
2x^2+3x−10=0

A. Irrational, because the answer is a decimal that does not repeat or terminate.
B. Rational, because the answer is a fraction.
C. Rational, because the answer is a whole number.
D. Irrational, because there is no solution to this quadratic.

how many players are there?

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
