a scientist notes that the number of bacteria in a colony is 50.3, hours later she notes that the number of bacteria has increas
Yuri [45]

The time it would take for the bacteria to reach 1119 is 5.83 hours

<h3>Calculations and Parameters:</h3>

Given the function:

Pt= P_0e^k^t

  • Initial amount= 50
  • amount after 3 hours= 80

To find the exponential growth;

80 = 50e^k^*^3

k= 1.6/3\\k= 0.533

If there is a constant growth, then to get to 1119:

1119= 50e^0^.^5^3^3^*t

3.8 = 0.533*t

t= 5.83 hours

Therefore, it would take 5.83 hours for the bacteria to increase to 1119.

What’s 40 41 42 43 44 45 46 47 48 49 50 IQR pls fast!!!!!
aliina [53]

Answer:

IQR = 6

Step-by-step explanation:

Given:

The given set of data is:

40 41 42 43 44 45 46 47 48 49 50

Number of terms, n=11

Therefore, the median is given as (\frac{n+1}{2})^{th} term which is the sixth term. Median = 45

(40 41 42 43 44) <u>45</u> (46 47 48 49 50 )

Now, we find the median of the lower half (Q_1) and upper half (Q_3)of the data that are before and after the median.

The lower half of the data has the values 40 41 <u>42</u> 43 44.

Number of terms are 5. So, median is the third term which is, Q_1=42

The upper half of the data has the values 46 47 <u>48</u> 49 50.

Number of terms are 5. So, median is the third term which is, Q_3=48

Now, IQR is given as the difference of upper half median and lower half median.

IQR=Q_3-Q_1\\IQR=48-42=6

A rectangle has a perimeter of 25 meters. If the lengths of the sides of the rectangle are multiplied by 7 to make a new rectang
juin [17]

Answer:

175 m

Step-by-step explanation:

We are given;

  • The perimeter of a rectangle as 25 m

We are required to determine the new perimeter if the sides of the rectangle are multiplied by 7.

We know that;

Perimeter of a rectangle = 2(L+W)

Therefore, initially;

2(L+W) = 25 m

Hence;

L + W = 12.5 m

if the sides are multiplied by 7, then;

New length = 7L

New Width = 7W

Thus;

New perimeter = 2(7L+7W)

                         = 14 (L + W)

but, L + W = 12.5

Thus;

New perimeter = 14 (12.5)

                         = 175 m

Therefore, the new perimeter will be 175 m
