Complete question is;

A group of biologists is surveying the mice population in a forest. The equation n=75⋅3t gives the total number of mice, n, t years since the survey began.

what does the number 3 mean in this situation.

1. the common difference

2. the total population

3. the common ratio

4. the slope

Answer:

3 is the common ratio

Step-by-step explanation:

We are given that the equation; n = 75⋅3^(t) gives the total number of mice, n, t years since the survey began.

Normally, formula when calculating population growth takes an exponential function;

n = n_o(e^(rt))

Or in this our case, it can be written as;

n = n_o((e^(r))^(t))

Comparing this with n = 75⋅3^(t), we can see that e^(r) = 3

Where r is the growth rate.

e is exponential constant.

Thus, we can say that 3 is the common ratio

A plastics stock dropped 1 1/4 points every day of a 5-day business week. How many points did the stock drop that week?

Answers

Answer:

That will be 1/14 points

Step-by-step explanation:

Answer:   6 & 1/4 points

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

Work Shown:

1/4 = 0.25

1 & 1/4 = 1 + 1/4 = 1 + 0.25 = 1.25

The stock dropped by 1.25 points each day for 5 days

It dropped a total of 5*1.25 = 6.25 = 6 & 1/4 points.

------------

Alternative method:

5*(1 & 1/4) = 5*(1 + 1/4)

5*(1 & 1/4) = 5*1 + 5*(1/4)

5*(1 & 1/4) = 5 + 5/4

5*(1 & 1/4) = 5*(4/4) + 5/4

5*(1 & 1/4) = 20/4 + 5/4

5*(1 & 1/4) = (20+5)/4

5*(1 & 1/4) = 25/4

5*(1 & 1/4) = (24+1)/4

5*(1 & 1/4) = 24/4 + 1/4

5*(1 & 1/4) = 6 + 1/4

5*(1 & 1/4) = 6 & 1/4

We get the same answer as before.

Alice's mother wants to wallpaper two adjacent walls in Alice's bedroom. She also wants to put a border along the top of all four walls. The bedroom is 9 ft by 12 ft by 8 ft high. A) If each double roll covers approximately 60 fr and the wallpaper is sold in double rolls only, how many double rolls are needed? B) If the border is sold in rolls of 5 yd each, how many rolls of the border are needed?

Answers

Answer:

A) The number of wallpapers needed to cover the walls is 6 double roll wall papers

B) The number of wall paper border rolls needed is 3 rolls

Step-by-step explanation:

A) The given parameters are;

The dimensions of the room are 9 ft. by 12 ft. by 8 ft. high,

The area one double role wallpaper covers = 60 ft.²

Therefore, we have;

The area of the room wall = 12 × 8 × 2 + 9 × 8 × 2 = 336 ft²

The number of double rolls of wallpaper to be used = Area of wall/(area of wallpaper) = 336/60 = 5.6

Therefore, given that the wall papers are sold in single units, we round up to the next whole number of units to get;

The number of wallpapers needed to cover the walls = 6 double roll wall papers

B) The borders of a wallpaper are installed parallel (and installed along) to the ceiling line

Therefore, the amount of wallpaper border required is given as follows;

Wall paper border length required = 2 × Length of the room + 2 × Width of the room

∴ Wall paper border length required = 2 × 9 ft. + 2 × 12 ft. = 42 ft.

The size of each wall paper border sold = 5 yd. = 15 ft.

Therefore;

The number of wall paper border rolls required = 42 ft./(5 yd.) = 42 ft./(15 ft.) = 2.8 rolls

Therefore, we round up to get the number of wall paper border rolls needed as 3 rolls of wall paper borders.

The area of Isaiah's bedroom is 13 1/3 square yards. His bed's area is 2 2/3 square yards. Find the unit rate and explain, in words, what it means in the context of this problem.

Answers

Answer:

5

Step-by-step explanation:

Area of bedroom = 13 1/3 square yards

Area of bed = 2 2/3 square yards

Unit Rate = Area of bedroom / Area of bed

Unit Rate = (40 / 3 ÷ 8/3)

Unit Rate = 5

A hair stylist knows that 87% of her customers get a haircut and 40% get their hair colored on a regular basis. Of the customers who get their hair cut, 24% also get their hair colored. What is the probability that a randomly selected customer gets their hair cut and colored?

Answers

Answer:

0.35

Step-by-step explanation:

The probability that a customer gets a hair cut and also gets a hair colored is 0.2088

What is probability?

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here: The probability of customers getting a haircut is 87% and the probability that the customers that have a haircut also get their hair colored are 24%

Thus the conditional probability that a customer who has a hair cut also gets his hair colored is

P( haircut/hair colored )= 87%×24%

                                      =0.87×0.24

                                      =0.2088

Hence, The probability that a customer gets a hair cut and also gets a hair colored is 0.2088

Step-by-step explanation:

The value of the function F(g(x) will be equal to (7 / 2).

What is a function?

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

Given functions are:-

f(x)=3x-7 g(x)= x +(1/x-1)

The function F(g(x) is written as :-

F(g(x) = 3 [ x + ( 1 / ( x-1 )) -7 ]

F(g(x) = 3 [ (3 + (1/2) - 7 ]

F(g(x) = 3 (7 / 2 ) -7

F(g(x) = ( 21/2) - 7

F(g(x) = ( 21-14 ) ( 2 )

F(g(x) = ( 7/2 )

Therefore the value of the function F(g(x) will be equal to (7 / 2).

What is the multiplicative identity of -12/13

A.-13/12

B.1

C.0

D12/13

Answers

Answer:

The number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.

Therefore, option (B) is true.

Step-by-step explanation:

We know that when a number let say 'n' get multiplied by '1', it remains unchanged.

i.e.

n × 1 = n1 × n = n

The number '1' is called the 'multiplicative identity' of a number 'n' because it does not change the number 'n' after getting multiplied by it.

Given the number

-12/13

Multiply the number '-12/13' by '1'.

i.e.

-12/13 × 1 = -12/13

1 × -12/13 = -12/13

Thus, the number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.

Therefore, option (B) is true.

In AWXY, X = 1.2 cm, ZX=45° and Y=108°. Find the length of w, to the nearest 10th

Answers

Answer:

The length of w is 0.8 cm

Step-by-step explanation:

In Δ WXY

x is the opposite side to ∠X

w is the opposite side to ∠W

y is the opposite side to ∠Y

∵ m∠X = 45°

∵ m∠Y = 108

∵ The sum of the measures of the interior angle of a triangle is 180°

45 + 108 + m∠W = 180

→ Add the like terms in the left side

∵ 153 + m∠W = 180

→ Subtract 153 from both sides

m∠W = 27°

Now we can use the sine rule to find the length of w

∵ [tex]\frac{w}{sin(W)}[/tex] = [tex]\frac{x}{sin(X)}[/tex] = [tex]\frac{y}{sin(Y)}[/tex]

→ Use the first 2 ratios to find w

∵ x = 1.2 cm

∵ [tex]\frac{w}{sin(27)}[/tex] = [tex]\frac{1.2}{sin(45)}[/tex]

→ By using cross multiplication

w × sin(45) = 1.2 × sin(27)

∴ w sin(45) = 1.2 sin(27)

→ Divide both sides by sin(45)

w = 0.7704474263

→ Round it to the nearest tenth

w = 0.8 cm

The length of w is 0.8 cm

: A coffee shop spends $408 for an order of 17 cases of paper cups. If the coffee shop adds 5 more cases of paper cups to the order, how much will the total cost be

Answers

Step-by-step explanation:

A case of paper cups costs $408 / 17 = $24.

5 more cases => 22 cases of paper cups total.

Hence the total cost will be 22 * $24 = $528.

Answer:

$528

Step-by-step explanation:

We find the unit rate of the cost per case.

$408 / 17 cases = $24/case

Each case costs $24.

Adding 5 cases to 17 cases, the order will be for 22 cases.

22 cases * $24/case = $528
