Answer:

(a)Initial Number of Bacteria=600

(b)[tex]\text{Number of bacteria after 5 days}=19200[/tex]

Step-by-step explanation:

Given an initial number  [tex]b_0[/tex] of bacteria in a petri dish, and each bacteria splits into 2 bacteria after one day.

The function [tex]b(d) = 600 \cdot 2^d[/tex] models  the number of bacteria, b after d days.

Part A

Given  [tex]b(d) = 600 \cdot 2^d[/tex]

When d=0,

The initial number of bacteria in the petri dish,

[tex]b_0=b(0) = 600 \cdot 2^0=600[/tex]

Part B

After 5 days, when d=5

[tex]b(5) = 600 \cdot 2^5=600 \cdot 32\\\text{Number of bacteria after 5 days}=19200[/tex]

16x - 20

Answer:

16x - 20

Step-by-step explanation:

Given

= 16x - 20

Answer:

(x+12)

Step-by-step explanation:

The middle number is 8 and the last number is -48.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 8

Multiply together to get -48

Can you think of the two numbers?

Try -4 and 12:

-4+12 = 8

-4*12 = -48

Fill in the blanks in

(x+_)(x+_)

with -4 and 12 to get...

(x-4)(x+12)

But, since (x-4) isn't an option, the answer would be (x+12)

Answer:

[tex]9\pi[/tex] sq. units.

Step-by-step explanation:

It is given that a circle has a sector with area [tex]\frac{1}{2}\pi[/tex] and central angle of [tex]\frac{1}{9}\pi[/tex] radians.  

We know that, the area of sector is

[tex]A=\dfrac{1}{2}r^2\theta[/tex]

where, r is radius and [tex]\theta[/tex] is central angle in radian.

Substitute the values of A and [tex]\theta[/tex].

[tex]\dfrac{1}{2}\pi=\dfrac{1}{2}r^2(\dfrac{1}{9}\pi)[/tex]

[tex]1=r^2(\dfrac{1}{9})[/tex]

[tex]9=r^2[/tex]

[tex]3=r[/tex]

The radius of the circle is 3 units.

So, the area of circle is

[tex]A=\pi r^2[/tex]

[tex]A=\pi (3)^2[/tex]

[tex]A=9\pi[/tex]

Therefore, the area of circle is [tex]9\pi[/tex] sq. units.

Final answer:

The base area of a cylinder with a volume of 150 cubic cm and a height of 10 cm is 15 square centimeters, obtained by dividing the volume by the height.

Explanation:

To find the base area of a cylinder with a known volume and height, we can use the formula for the volume of a cylinder: V = πr²h, where V is the volume, r is the radius of the base, and h is the height. Since the volume (V) is 150 cubic cm and the height (h) is 10 cm, we can rearrange the formula to solve for the base area (A): A = V/h.

By substituting the given values into our rearranged formula, we get: A = 150 cm³ / 10 cm = 15 cm². Thus, the base area of the cylinder is 15 square centimeters.

Answer:

0.33

Step-by-step explanation:

because 0.45 plus 0.22 is 0.67 which means the other probability is 0.33.

The probability of dying from some other cause will be 0.33. Probability always lies between 0 and 1.

The chances of an event occurring are defined by probability. Probability has several uses in games, in business to create probability-based forecasts,

The given data in the problem is;

P(A) is the probability of dying from cardiovascular disease = 0.45

P(B) is the  probability of dying from cancer = 22

P is the probability of dying from some other cause =?

The probability of dying from some other cause will be found as;

[tex]\rm P =1- P(A)+P(B) \\\\ \rm P =1- 0.45+0.22 \\\\ \rm P =0.33[/tex]

Hence the probability of dying from some other cause will be 0.33.

Step-by-step explanation:

Change all the fractions to decimals.

-2/5 = -0.4  Distribute that over x and 0.8   1/50 =  0.02

you get -0.4x -0.32 + 0.02

Change all the decimals to fractions.

0.8 is 8/10  so  -2/5 times 8/10  is -16/50

Answer:

25 and 15

You can easily make a system of equations:

x + y = 40

x - y = 10

Solving for x on equation 2 gets x = 10 + y.

Plugging in this into the first equation, you get 10 + y + y = 40

Thus, 10 + 2y = 40

y = 15.

Plugging this back into either equation gets x = 25.

From the given set of fractions, 13/16 is the largest fraction.

The given set of fractions are 13/16, 3/4, 7/10, and 5/8.

We need to check which of the given fractions is the largest.

To order fractions from least to greatest, start by finding the lowest common denominator for all of the fractions. Next, convert each of the fractions by dividing the lowest common denominator by the denominator and then multiplying the top and bottom of the fraction by your answer.

Now, the LCM of denominators of the fractions is as follows:

16, 4, 10 an 8 LCM= 2×2×2×2×5=80

Make the denominators equal to LCM.

That is, 65/80, 60/80, 56/80, and 50/80

Here, 65/80 is the largest, since the numerator is the greatest number.

Therefore, from the given set of fractions 13/16 is the largest fraction.

Answer:

y=6

Step-by-step explanation:

y² - 10y + 24

factor: y - 4

24 / -4 = -6

y - 6 is the other factor.

(y-4)(y-6) ⇒ y(y-6) -4(y-6) = y² - 6y -4y + 24 ⇒ y² - 10y + 24

please mark as brainliest plzzzzzzzzz

The other factor of the expression y² - 10y + 24, other than y - 4, is y - 6. The expression can be factored as (y - 4)(y - 6).

The given expression is y² - 10y + 24. You have given that one factor is (y - 4). To find the other factor of the equation, we can divide the whole equation by (y - 4). By doing this, we find out that the other factor is (y - 6).

So, the expression y² - 10y + 24 can be factored as (y - 4)(y - 6).

This concludes that other than (y - 4), the other factor of the expression y² - 10y + 24 is (y - 6).

Answer:

A

Step-by-step explanation:

i promise it's A.

Mona is hang gliding 1.25 kilometers above sea level and a whale is 0.2 kilometers below sea level. The total distance between them is the sum of both distances, which is 1.45 kilometers.

The distance between Mona and the whale is given by the sum of 2 distances. One is Mona's altitude above sea level (5/4=1.25 kilometers) and the other is the whale's depth below sea level (0.2 kilometers). Both values should be added because both distances are defined with respect to the sea level, and their signs indicate direction rather than distance. Therefore, the expression that represents the distance between Mona and the whale is 1.25 km+0.2 km = 1.45 km, where 1.25 km is the distance Mona is gliding above the sea level and 0.2 km is the distance the whale is under the sea level.

Answer:

1) B. on, 2) D. 19.2, 3) C. 0

Step-by-step explanation:

1) The value of y according to the regression line is:

[tex]y = 3.2\cdot (8) - 6.4[/tex]

[tex]y = 19.2[/tex]

Hence, the point (8,19.2) is on the least-squares regression line.

2) The value of y according to the regression line is 19.2.

3) The residual is the difference between the value from the regression line and the real value. In this case, the residual value is 0.

Final answer:

The data point (8,19.2) lies on the least-squares regression line. The value of the least-squares regression line at x=8 is 19.2. Hence, the residual of the data point (8,19.2) is 0.

Explanation:

The data point (8,19.2) is on the least-squares regression line since when we substitute x=8 into the equation y=3.2x−6.4, we get y=3.2(8)−6.4 which simplifies to y=25.6−6.4, yielding y=19.2, which is exactly the y-value of the given data point.

The value of the least-squares regression line at x=8 is therefore 19.2 which corresponds to option D.

Since the observed y-value is exactly predicted by the regression line at this x-value, the residual for the data point (8,19.2) is 0, which represents the difference between the observed y-value and the value predicted by the regression formula. Therefore, option C is correct for the residual.
