Suppose that the probability distribution for birth weights is normal with a mean of 120 ounces and a standard deviation of 20 ounces.

1.The probability that a randomly selected infant has a birth weight between 100 ounces and 140 ounces is 68%.
2.The probability that a randomly selected infant has a birth weight between 110 and 130 is 68%.

Atriangular field has sides of lengths 21, 39, and 41 yd. find the largest angle. (round your answer to the nearest degree.)

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
