Answer:
A
Step-by-step explanation:
The opposite angles in a parallelogram are congruent, thus
∠ C = ∠ A = 57°
62=2×31
82=2×41
so the answer is 2
It would take 1minute and 10 seconds to complete the job because you have to subtract 2hours (2:00) by 90seconds (0:90)
The 99% confidence interval for the true mean is given by:

where:

is the sample mean = 69.7

is the standard deviation = 2.8

is the test statistics = 2.58 for for 99% confidentce interval.
n is the sample size = 772.
Therefore, the 99% confidence interval is:
Do 120 seeds - 90 that have sprouted.
120-90= 30
30 divide by the total number of planted 120 seeds
30/120= 1/4
1/4 times 100 to get the percent
1/4*100
Cross out 4 and 100 , divide by 4 . 4/4= 1
100/4= 25
1/4=25 %
Answer: 25%
