x = -4 / 2(2)
x = -1
y = 2(-1)² + 4(-1) + 8
y = 2 - 4 + 8
y = 10 - 4
y = 6

Answer:
first answer is 9.84
Step-by-step explanation:
9.84 is the square root of 97, rounded to the nearest hundredth.
the legs measure 9 x 9 and 4 x 4 = 81 and 16.
81 + 16 = 97, so your answer is the square root of 27, which rounded to the nearest hundredth, equals 9.84. Rounding towards the nearest whole, 10 would be your best bet.
hope this helps!!
Answer:
Proportion of female older Than 60 in country A is not more than the proportion of female older Than 60 in country B.
Step-by-step explanation:
From. The plot given :
We could approximate the proportion of females older than 60 as follows _
COUNTRY A :
60 - 69 = 0.105
70 - 79 = 0.065
80 - 89 = 0.038
90+ = 0.01
Total = About 0.218
COUNTRY B :
60 - 69 = 0.14
70 - 79 = 0.11
80 - 89 = 0.07
90+ = 0.02
Total = About 0.34
From the estimated proportion, the proportion of females on country B is more than the proportion in country A.
Answer:
B
