Dr. Caras was characterizing a cytochrome (an iron containing protein) from a new strain of bacteria. He obtained the following

olya-2409 [2.1K]

Answer:

0.5613

Step-by-step explanation:

Here mean strain of bacteria x = sum of all numbers/ total numbers = 0.5514 %

Standard deviation s = 0.0040 %

Test statistic

G = (x_{max} -x)/s = (0.5613 - 0.5514)/ 0.0040 = 2.475

95% confidence value for outlier for n = 8 and alpha = 0.05

G_{critical} = 2.1266

so here we see that G > G_critical , so we reject that the there is no outlier . the value of 0.5613 is and outlier.

If a rock falls from a height of 40 meters on Earth, the height H (in meters) after x seconds is approximately

Julli [10]

Once the rock hits the ground, we know that its height will be equal to 0m
because of this, we can replace H(x) with 0
$40 - 4.9 {x}^{2} = 0$
now all we have to do is get x by itself
so..
$4.9 {x}^{2} = 40$
then
${x}^{2} = 40 \div 4.9$
${x}^{2} = 8.1632...$
now take the square root of each side
$x = 2.857...$
2.857 seconds (rounded to the third decimal)
