Answers

Answer: Bottom left

5x5x5=125

The volume having 125 cubic, is a box which has dimensions,  5 feet, 5 feet, 5 feet. So Option D is correct

What is Volume?

In mathematics, Space occupied by three dimensional objects is called Volume. Basically it is a space within a closed region of every three dimensional object.

Given that,

4 boxes having different different dimensions

1. 4 feet, 9 feet, 5 feet

2. 4 feet, 3 feet, 4 feet

3. 5 feet, 12 feet, 2 feet

4. 5 feet, 5 feet, 5 feet

lets calculate the volume for all the four boxes

V = 4 feet  × 9 feet  × 5 feet  = 180  feet³

V = 4 feet × 3 feet × 4 feet  = 48 feet³

V =  5 feet × 12 feet × 2 feet  = 120 feet³

V =  5 feet × 5 feet × 5 feet  = 125  feet³

Hence, the volume of box having dimension 5 feet, 5 feet, 5 feet is 125  feet³

A population of 50 deer are introduced into a wildlife sanctuary. It is estimated that the sanctuary can sustain up to 500 deer. Absent constraints, the population would grow by 40% per year.

Estimate the population after one year

p1 =


Estimate the population after two years

p2=

Answers

Answer:

p1 = 70 deer

p2 = 98 deer

Step-by-step explanation:

We use the population growth expression:

[tex]N(t)=N_0\,(1+r)^t[/tex]

which in our case renders:

[tex]N(t)=N_0\,(1+r)^t\\N(t)=50\,(1+0.4) ^t\\N(t)=50\,(1.4) ^t[/tex]

Therefore, after 1 year the population would be:

[tex]N(1)=50\,(1.4) ^1=70[/tex]

giving a total of 70 deer

and after two years, it would be:

[tex]N(2)=50\,(1.4) ^2=98[/tex]

Which transformation from the graph of a function f(x) describes the graph of 5f(x)

Answers

Answer:

Dilation

Step-by-step explanation:

Given

Main function: f(x)

Resulting function: 5f(x)

Required

Which transformation exists between both functions

The general explanation is that:

When a function f(x) is multiplied by a constant k, the resulting function g(x) is a dilation of f(x).

Mathematically, if the following relationship exists between f(x) and g(x)

g(x) = k.f(x)

Then g(x) is a dilation of f(x) and k is the constant of proportionality or dilation ratio

In this case:

g(x) = 5f(x)

So, the transformation that answers the question is dilation.

What is the present value of ₱30,000 due in 27 months at 3% compounded annually?

Answers

Answer:

32,063.06

Step-by-step explanation:

the formula for compound interest: [tex]A = P(1+\frac{r}{n})^{nt\\}[/tex]

so to use this you are essentially solving for a.

p is the principle (or initial) amount deposited.

r is the rate (in percent)

n is the number of time periods compounded (like annually, monthly, weekly, or daily)

t is the time period (in years)

In this instance the formula looks like: [tex]A = 30,000(1+\frac{0.03}{1})^{1*2.25}[/tex]

You then solve for A using the formula. It is important to remember to use the order of operations

Step-by-step explanation:

The random variable x is the number of occurrences of an event over an interval of ten minutes. It can be assumed that the probability of an occurrence is the same in any two time periods of an equal length. It is known that the mean number of occurrences in ten minutes is 5.4. The probability that there are more than 5 occurrences in ten minutes is:____.a. .0241.b. .0771.c. .1126.d. .9107.The random variable x satisfies which of the following probability distributions?
A. Normal.B. Poisson.C. Binomial

Answers

The options given don't correspond to the values in the question. The options are from another question where mean is 5.3 and the probability being looked for is for exactly 3 occurrences and 5 occurrences

Answer:

A) 0.6511

B) Poisson distribution

Step-by-step explanation:

We are given;

Mean: μ = 5.4 minutes

Now, we want to find the probability that there are more than 5 occurrences in ten minutes.

This will be written as;

P(x > 5) = 1 - P(x < 5)

P(x < 5) = P(x = 4) + P(x = 3) + P(x = 2) + P(x = 1) + P(x = 0)

We will use Poisson distribution for this. The formula is;

P(x) = [(e^(-μ)) × μ^(x)]/x!

P(0) = [(e^(-5.4)) × 5.4^(0)]/0! = 0.004517

P(1) = [(e^(-5.4)) × 5.4^(1)]/1! = 0.02439

P(2) = [(e^(-5.4)) × 5.4^(2)]/2! = 0.06585

P(3) = [(e^(-5.4)) × 5.4^(3)]/3! = 0.11853

P(4) = [(e^(-5.4)) × 5.4^(4)]/4! = 0.16

Thus;

P(x < 5) = 0.16 + 0.11853 + 0.06585 + 0.004517 = 0.3489

Thus;

P(x > 5) = 1 - P(x < 5) = 1 - 0.3489 = 0.6511

B) like seen from solution A above, we used Poisson distribution formula.

Thus, random variable x satisfies Poisson distribution

If x and y are 2 complementary angles then find the value of y if measure of angle x is 20 degree
plz help me I am marking branliest to the correct answer

Answers

Answer:

y=70 degrees

Step-by-step explanation:

If 2 angles are complimentary, they add up to 90 degrees.

x+y=90 degrees

x=20 degrees

y=90-20 degrees

y=70 degrees

If that is wrong, try this. Let's say the questions gives us the fact that x is 20 degrees greater than y.

y=x

Substituting x for y, the equation is x+x+20=90

Since y is x, x would also be y, which is 35. then x+20 would be 55.

So y would be 35.

THE ANSWER WOULD BE 70 DEGREES, BUT IF THAT IS WRONG, DO THE SECOND ONE, WHICH IS 35

(c, 2 points) Based on your answer for b, are the events ‘at least one math major is selected to present on Monday' and 'two computer science majors and a math major present on Tuesday' independent?

Answers

Answer:

a}[tex]P_1= 0.3[/tex]

b)[tex]P_2 =0.45[/tex]

c) NOT INDEPENDENT

Step-by-step explanation:

From the question we are told that

Sample space

Math majors are 3

computer science majors are 3

Generally the sample space is

Mathematically the sample space required on Monday is given as  [tex]S_m= 3c_1 * 3C_2[/tex]

where [tex]S_m[/tex] =sample space on Monday

Therefore,

[tex]P_1[/tex] = [tex]\frac{3C_1 *3C_2}{6C_3}[/tex]

[tex]P_1=\frac{3*3}{20}[/tex]

[tex]P_1=\frac{6}{20}[/tex]

b)

Generally the the equation is given as

[tex]P_2 =P(\frac{x \cap y}{y})[/tex]

where

x  is  selecting two math major and 1 computer science major on Monday

y is at leas one math major selected

[tex]P_2 =\frac{^3C_1*^3C_2}{^3C_1*^3C_2 + ^3C_2*^3C_1 +^3C_3*^3C_0}[/tex]

[tex]P_2 =\frac{3*3}{3*3 + 3*3 +^1*1}[/tex]

c)

Generally in representing independent events

[tex]P_3=p(x \cap y)[/tex]

=>[tex]p(x) * p(y)[/tex]

Mathematically

[tex]n(x)= ^3C_1 *^3C_2[/tex]

[tex]n(y)={^3C_1*^3C_2 + ^3C_2*^3C_1 +^3C_3*^3C_0}[/tex]

therefore

[tex]n(x \cap y) =^3C_1 *^3C_2[/tex]

This does not satisfy the two equations stated above therefore NOT INDEPENDENT
