The population of bacteria in a Petri Dish is growing at a rate of 0.8t^3 + 3.5 thousand per hour. Find the total increase in ba

aliina [53]

Answer:

$p=9900\\$ bacterias in the initial two hours

Step-by-step explanation:

the growing rate is given by the ecuation

$p(t)=0.8(t)^{3} +3.5$ thousand per hour

for t=2 we have

$p(2)=0.8(2)^{3} +3.5 = 9.9$ thousand

$p=9900\\$ bacterias

In two hours we have 9900 bacterias

When sample size increases Group of answer choices

Olenka [21]

Answer:

Option A)

Confidence interval decreases

Step-by-step explanation:

If we increase the sample size, then,

The standard error of the interval decrease.
If the standard error increase, the margin of error of the interval decrease.
If the margin of error decreases, the width of the confidence level decreases, hence, the confidence interval become narrower.

Thus, the correct answer is

Option A)

Confidence interval decreases

Graph the image of the figure using the transformation given.<br>reflection across y=-1

Vikki [24]

Answer:

I'm not graphing, but I can describe the reflection as R', S', T', U':

R' = (-3, 1)

S' = (-2, 0)

T' = (-1, 2)

U' = (-2, 2)

Step-by-step explanation:

y = -1 is the line one unit below the x axis (the x axis is y=0).

To reflect any point across y=-1, we just need to leave the x coordinate as was, but the (new y) will be -2-(old y)

R = (-3, -3), R' = (-3, -2+3) = (-3, 1)

S = (-2, -2), S' = (-2, -2+2) = (-2, 0)

T = (-1, -4), T' = (-1, -2+4) = (-1, 2)

U = (-2, -4), U' = (-2, -2+4) = (-2, 2)
