Answer:

  A: a = 100

  B: b = 2

Step-by-step explanation:

The problem statement tells you that the population of bacteria is 100 at the start of our observation.

  t = 0, f(t) = f(0) = 100

If you remember that a 0 exponent means the value is 1, then you know ...

  f(0) = a·b^0 = a·1 = a

Since f(0) = 100, we know a = 100.

__

An exponent signifies repeated multiplication.

We know the population at t=0 is 100. At t = 1, we are told the population doubles. That means it is multiplied by 2.

 f(1) = 100·b^1 = 100·2

  b^1 = 2 . . . . . . . . . . . . . . . matching parts of these expressions

  b = 2 . . . . . . . . . . . . . because b^1 = b

Answer:

30 yards of fence

Step-by-step explanation:

First, convert 60 feet to yards and 30 feet to yards. Remember, 1 foot= 3 yards.

60/3= 20 yards

30/3= 10 yards

Then you add the length and the width of the fence (in yards) to find the total yards of fence.

20+ 10= 30 yards of fence

ŷ = –0.227x + 50.455

x represents the price of bobbleheads (measured in dollars)

ŷ is the predicted demand of bobbleheads (in units).

Preductwd demand ; when x = 6

ŷ = –0.227(6)+ 50.455

= 49.093

Answer:

97/139

Step-by-step explanation:

You add every thing but red so 45+20+32 which equals 97, so 97 is your numerator and to get the denominator you add all the numbers together so 42+45+20+32 which equals 139.

Probability that candy picked is purple or not red is [tex]\frac{32}{151}[/tex].

The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes. The value of the probability of an event to happen can lie between 0 and 1 because the favorable number of outcomes can never cross the total number of outcomes. Also, the favorable number of outcomes cannot be negative.

According to the question

A bag contains 42 red, 45 green, 20 yellow, and 32 purple candies.

You pick one candy at random.

We have to find probability that it is purple or not red.

Formula for probability:

[tex]P(E) = \frac{Number \ of \ favorable \ outcomes}{Total \ number \ of \ favorable \ outcomes}[/tex]

Total number of favorable outcomes = [tex]42+45+20+32 =151[/tex]

Number of favorable outcomes = 32

Probability that it is purple or not red.

[tex]P(E)=\frac{32}{151}[/tex]

Hence, Probability that candy it is purple or not red is [tex]\frac{32}{151}[/tex].

Answer:

y = 6

Step-by-step explanation:

line of an equation: y = mx +c

where c is y-intercept, m is gradient and y and x are the y and x coordinates.

For finding the line of an equation we first find a gradient

gradient = (y2 -y1) / (x2 - x1)

so; (6-6) / (7-(-5)) = 0/12 = 0

next using any pair of coordinates we will find the c (y-intercept)

6= 0 (-5) + c

c = 6

so the equation will be

y = mx + c

(add the values you just found)

y = (0)x + 6 (since anything multiplied by 0 is 0 so we can write its like;)

y = 6

Answer:

[tex]\boxed {\boxed {\sf b=60 \ meters}}[/tex]

Step-by-step explanation:

This is a right triangle because of the small square in the corner representing a 90 degree angle.

Therefore, we can use the Pythagorean Theorem.

[tex]a^2+b^2=c^2[/tex]

Where a and b are the legs and c is the hypotenuse.

80 and b are the legs, because they form the right angle. 100 is the hypotenuse because it is opposite the right angle.

[tex]a=80 \\b=b \\c=100[/tex]

[tex](80)^2+b^2=(100)^2[/tex]

Solve the exponents.

[tex]6400+b^2=10000[/tex]

Solve for the unknown by isolating the variable. First, subtract 6400 from both sides.

[tex]6400-6400+b^2=10000-6400\\b^2=3600[/tex]

Take the square root of both sides.

[tex]\sqrt {b^2}= \sqrt {3600}\\b=60 \\b= 60 \ m[/tex]

The missing leg is 60 meters.

THIS IS ALL I COULD HELP I AM SORRY!

==========================================================

Explanation:

For each row, divide the earnings over the sales.

All of these decimal values have the following conversions to percentages

If we add up those percentages and divide by 4, we get the average percentage

(3.27+2.85+3.08+2.90)/4 = 3.025

So the average percentage of these four is 3.025%

So for instance, if you made $1000 in sales, then 0.0325*1000 = 32.50 would be the estimated earnings.

A good estimate in my opinion is the equation c = 0.0325d since 3.025% converts to the decimal form 0.0325

Another method you could use is linear regression to help estimate. Though this method is a lot more complicated involving many more steps. It's better to use technology (eg: graphing calculator) if you go this route. The linear regression line is approximately y = 0.02896x + 2.00732; we can see the slope 0.02896 isn't too far off from 0.0325. Other forms of regression are possible as well.

Answer:

x = 5

Step-by-step explanation:

the supplementary angle of (19x-18) = 180 - (19x-18) = 198-19x

all interior angles of a triangle = 180 degrees

180 = (7x+1) + (10x-9) + (198-19x)

180 = 7x+10X-19x+1-9+198

180 = -2x+190

-2x = -10

x = 5
