Answer:
The correct expression to calculate the number of bees after t days if the initial swarm had 1000 bees is [tex]P = 1000 *e^{0.2*t}[/tex]
Step-by-step explanation:
Given -
The population of a swarm of killer bees increases by 10 times in 50 days
The rate of increase of population is [tex]r = \frac{10}{50} = 0.2[/tex] per day
As we now the equation of population projection is
[tex]P= P_0 *e^{rt}\\[/tex]
Where P0 = initial population
P is the population after time t
and r is the rate of increase of population
Substituting the given values in above equation, we get -
[tex]P = 1000 *e^{0.2*t}[/tex]

Miguel weighs himself and discovers he weighs 83,600 grams. How many kilograms does Miguel weigh?
The solution is, 83.6 kilograms does Miguel weigh.
What is unit conversion?A unit conversion expresses the same property as a different unit of measurement. For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.
here, we have,
given that,
Miguel weighs himself and discovers he weighs 83,600 grams.
now.,, we have to find that how many kilograms does Miguel weigh.
we know that,
1000 grams = 1 kg
so, we have,
he weighs 83,600 grams
so,
as, 1000 grams = 1 kg
so, 1 gram = 1/1000 kg
we get,
83,600 grams = 1/1000 * 83,600 kg
i.e. 83,600 grams = 83.6 kg
Hence, 83.6 kilograms does Miguel weigh.

Cal uses the equation y = 2.92
+ 2.4 to model his data. Use this equation to make the
following predictions.
Enter a number in each space provided
After 25 weeks, Cal will have saved a total of $____
The least number of whole weeks Cal must save to have a total of $100 saved is ____
Answer:
(a) $62.92 saved in 25 weeks
(b) 41 weeks to save $100
Step-by-step explanation:
Given
[tex]y = 2.92 + 2.4x[/tex]
[tex]x \to weeks[/tex]
[tex]y \to savings[/tex]
Solving (a): Savings in 25 weeks.
This means that: x = 25
So:
[tex]y = 2.92 + 2.4x[/tex]
[tex]y = 2.92 + 2.4 * 25[/tex]
[tex]y = 2.92 + 60[/tex]
[tex]y = 62.92[/tex]
Solving (b): Whole weeks to save $100
This means that x = 100
So:
[tex]y = 2.92 + 2.4x[/tex]
[tex]100 = 2.92 + 2.4x[/tex]
Collect like terms
[tex]2.4x = 100 - 2.92[/tex]
[tex]2.4x = 97.08[/tex]
Solve for x
[tex]x = 97.08/2.4[/tex]
[tex]x = 40.45[/tex]
Round up
[tex]x = 41[/tex]

immma send you the link friend me on hereStep-by-step explanation:
The function g(t)=−16t2+vt+h represents the height of an object, g, in feet, above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet. A model rocket is launched off the ground at an initial velocity of 80 feet per second. Part A: Write a function that can be used to describe the flight of the model rocket. Part B:What domain makes sense for this function in context?
Answer:
A) g(t) = - 16*t² + 80*t
B) domain is ( 0 ≤ t ≤ 5 )
Step-by-step explanation:
A) for the model rocket
h = 0 and v = 80 feet/sec
Then the equation g(t) = -16*t² + v*t + h
became
g(t) = - 16*t² + 80*t + 0 g(t) = - 16*t² + 80*t
B) The equation g(t) = - 16*t² + 80*t is defined for all real numbers then the domain interval for t is ( -∞ , ∞ ). Now in our case, a model rocket was launched is not possible to get negative values for g(t) then the biggest value for t = 5 from
-16*t² + 80*t ≥ 0
-16*t ≥ -80 16*t ≤ 80
t ≤ 5
And the domain is ( 0 ≤ t ≤ 5 )

Answer:
y=-3x+10
Step-by-step explanation:
Since you know that the equation of the line is perpendicular to 1/3, you have to find the inverse of 1/3. You swap the denominator and numerator and make the number negative. In this case, it will be -3. Now that you know the slope is -3, you can use the equation y-y1=m(x-x1) where m is the slope. We know that the point (2,4) is in the graph so we can plug it into the equation. y-4=m(x-2). We know that the slope is -3 so we can plug it into the equation. y-4=-3(x-2). Simplify this to get y-4=-3x+6. Simplify this to get y=-3x+10. This means that the answer is y=-3x+10.

Step-by-step explanation:
An NBA fan named Mark claims that there are more fouls called on his team any other team, but the commissioner says that the number of fouls called against his team are no different than any other team. Mark finds that the average number of fouls in any game in the NBA is 11.5. He takes a random sample of 34 of games involving his team and finds that there are an average of 12.2 fouls against his team, with a standard deviation of 1.6 fouls. What is the correct conclusion
Answer:
Fouls > Average Fouls
Step-by-step explanation:
Null Hypothesis [ H0 ] : Fouls = Average Fouls ie 11.5
Alternate Hypothesis [ H1 ] : Fouls > Average Fouls
t = ( x - u ) / ( s / √n )
where x = actual observed mean = 12.2 here , u = assumed population mean = 11.5 , s = sample standard deviation = 1.6 , n = sample size = 34
So, t = (12.2 - 11.5 ) / ( 1.6 / √34 ) = 0.7 / ( 1.6 / 5.83 ) = 0.7 / 0.275 = 2.55
t tabulated value for α = 5% right tailed = 1.645 , ie < calculated value 2.55 So , we reject the null hypothesis, & conclude that 'Fouls > Average Fouls'

What are permutations?The different arrangements which can be made out of a given number of objects by taking out some or all at a time are called permutations.
Suppose there are n items.
Suppose we have

Answer:
El comerciante NO PUEDE guardar todas las cajas de zapatos en el cajón
Step-by-step explanation:
Tenemos que encontrar el volumen de la caja.
Se nos dice en la pregunta que:
Coloca 20 a lo largo, 7 a lo ancho y 8 a la altura.
Volumen = Largo × Ancho × Alto
Largo = 20, Ancho = 7, Alto = 8
Volumen = 20 × 7 × 8
= 1120

From previous experience, the owner of an apple orchard knows that the mean weight of Gala apples is 140 grams. There has been more precipitation than usual this year. The owner believes the weights of the apples will be heavier than usual and therefore the crop will be more profitable. This will allow the owner to expand the orchard. The owner takes a random sample of 30 apples and records their mean weight. What is the consequence of a Type I error in this situation?
The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually greater than 140 grams.
The owner believes the crop will not be more profitable and does not expand the orchard when the true mean weight of the apples is actually greater than 140 grams.
The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually not greater than 140 grams.
The owner believes the crop will not be more profitable and does not expand the orchard when the true mean weight of the apples is actually not greater than 140 grams.
Answer:
C, The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually not greater than 140 grams.
Step-by-step explanation:
Using error concepts, it is found that the consequence of a Type I error in this situation in this situation is given by:
The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually not greater than 140 grams.
What are the hypotheses test?At the null hypotheses, it is tested if the weights are not heavier, that is:
[tex]H_0: \mu = 140[/tex]
At the alternative hypotheses, it is tested if they are heavier, that is:
[tex]H_1: \mu > 140[/tex]
A Type I error is the rejection of a true null hypothesis, that is, concluding that the weights are heavier and more profitable when they are not. Hence the correct option is:
The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually not greater than 140 grams.

Only one triangle can be formed for any valid group of triangle lengths. The sides are a fixed length, and when joined, will have fixed internal angles. You cannot form the triangle with different angle sizes because the lengths are fixed. The orientation of the triangle may be different (the 14 ft fence is to the side in one drawing, or the top in another) but it is still the same triangle.

find the area of the kite.
A. 27 square units
B. 40 square units
C. 18 square units
D. 36 square units
Answer:
36 unit^2.
Step-by-step explanation:
The area is the sum of the 2 triangles with each having base between the points (-2,4) and (-2,-4).
The base is4 - -4 = 8.
Area of a triangle = 1/2 * base * height.
Area of the kite = 1/2 * 8 * 3 + 1/2 * 8 * 6
= 12 + 24
= 36.
