Answer:
x1= -7 , x2 = 7
Step-by-step explanation:
x^2 = 37 +12
x^2 = 49
x = -7 or 7
Answer:
34.1
Step-by-step explanation:
8 4/5 is not needed. The other two will given you the answer.
Area = 1/2 * b * h
b = 12 2/5 = 12.4
h = 5 1/2 = 5.5
Area = 1/2 * 12.4 * 5.5
Area = 34.1 square feet.
The sequence is to multiply by -3. Therefore, you want to multiply by -3 which gives you 108. Since it is a negative by a positive the answer would be negative. The next term would be -108.
Answer:
0.27
Step-by-step explanation:
The probability P that exactly two babies were born deaf can be gotten by the binomial distribution as

where n is the sample size (the number of babies randomly surveyed), k is the number of success, i. e., the baby is deaf; and p is the probability of selecting a deaf baby = 2/1000 = 0.002. Therefore
