Answer:

g(x) = [tex]8(\frac{1}{2})^x[/tex]

Step-by-step explanation:

Let the equation of the graphed exponential function is,

g(x) = [tex]a(b)^x[/tex]

Two points (0, 8) and (1, 2) lie on this graph.

For (0, 8),

g(0) = [tex]a(b)^0[/tex]

8 = a(1)

a = 8

For other point (1, 2),

g(1) = [tex]a(b)^1[/tex]

2 = ab

2 = 8b

b = [tex]\frac{2}{8}[/tex]

b = [tex]\frac{1}{4}[/tex]

Therefore, given exponential function wiil be,

g(x) = [tex]8(\frac{1}{2})^x[/tex]

Answer:

[tex]270 \:m^2[/tex]

Step-by-step explanation:

The area of the triangle.

[tex]bh\frac{1}{2}[/tex]

[tex]b \times h \times \frac{1}{2}[/tex]

[tex]20 \times 27 \times \frac{1}{2}[/tex]

[tex]540 \times 1/2[/tex]

[tex]=270[/tex]

The area of triangle would be;

⇒ Area of triangle = 270 m²

Since, A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Here, Given that;

Base of triangle = 20 m

Height of triangle = 27 m

Now, We know that;

Area of triangle = 1/2 × Base × Height

Substitute all the values, we get;

⇒ Area of triangle = 1/2 × Base × Height

⇒ Area of triangle = 1/2 × 20 × 27

⇒ Area of triangle = 270 m²

Thus, The area of triangle would be;

⇒ Area of triangle = 270 m²

Answer:

The plans will cost the same for $260 minutes of calling.  These minutes will cost $52.20

Step-by-step explanation:

Plan A:  $8 + ($0.17/min)t

Plan B:  $21 + ($0.12/min)t

Equate these, obtaining $8 + ($0.17/min)t = $21 + ($0.12/min)t, or:

($0.17/min)t - ($0.12/min)t = $13, or

($0.05/min)t = $13 , so t = 260 minutes.  The plans will cost the same for $260 minutes of calling.

Find the cost in this situation:  It is $21 + ($0.12/min)(260 min), or $52.20

Answer:

903 sq. cm.

Step-by-step explanation:

It is given that the length of two parallel sides of a trapezium are 91 cm and 51 cm and the length of two other side 37 CM and 13 cm respectively.

Now draw a dotted line as shown in the below figure. So, we have a triangle with sides 13 cm, 37 cm, 40cm and a parallelogram with sides 51 cm, 13 cm.

Area of parallelogram is

[tex]A_1=base\times height[/tex]

[tex]A_1=51\times 13[/tex]

[tex]A_1=663[/tex]

Using heron's formula, area of triangle is

[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]

where, [tex]s=\dfrac{a+b+c}{2}[/tex].

The sides of triangle are 13cm, 37 cm, and 40 cm.

[tex]s=\dfrac{13+37+40}{2}=45[/tex]

Area of triangle is

[tex]A=\sqrt{45(45-13)(45-37)(45-40)}=240[/tex]

The area of trapezium is

[tex]A=A_1+A_2=663+240=903[/tex]

Therefore, the area of trapezium is 903 sq. cm.

Answer:

6 hot dogs package assuming she's buying a single package to contains 10 package or approximately 8 rolls if she buys the 8 package containing above 60 rolls of hot dogs.

In my opinion, she needs at least 8 package of hot dog rolls to make hot dogs for her guests.

Step-by-step explanation:

Hello,

There are typically 10 hot dogs in a single package. However some may contain 8 hot dogs rolls in a single pack so we'll solve for both in case which ever one she decides to buy.

My teacher is expecting 30 guests coming to the party and each 1 one them wants to eat 2 hot dogs.

To solve this question, we would first of all know the total number of hot dogs they'll probably eat at the party.

2 hot dogs = 1 person

y hot dogs = 30 people

y = (30 × 2) / 1

y = 60 hot dog.

Therefore, the guest would most likely consume at least 60 hot dogs at the party.

However, in a single hot dog package, it contains 10 hot dogs in it.

Now we'll have to find out the total number of hot dogs package my teacher needs to buy to prepare the hot dogs for her guests.

To do that, we'll have to divide the total number of hot dogs expected to be consumed by the total number of hot dogs in one package.

Number of package = total number of hot dogs expected to be consumed / total number of hot dogs in one package.

Number of package she needs = 60 / 10

Number of package she needs = 6

Therefore, my teacher requires 6 hot dog package.

But some hot dogs comes in 8 rolls per package

Using the same method above,

Number of rolls she needs = 60 / 8

Number of rolls she needs = 7.5 approximately 8 rolls

Answer:

You can't use this rule because the two exponents have different bases. In order to use this rule the two exponents must have the same base.

Answer:

It is because both expressions have different base value. For this question, the bases are 3 and 2 where the product rule cannot be applied. Product rule can only be used when both expressions have the same bases.

Answer:

28 days

Step-by-step explanation:

because the frog climbs 3m in the day, but falls 2m at night, it technically climbs 1m every 24 hours. this means after the 1st day, it will have climbed a total of 1m, on the second, it will have climbed a total of 2m, and so on. however, when it gets nearer to the top, that's when things start to change. after the 26th day, it will have climbed 26m. on the 27th day, it will be 27m, but then when it jumps 3m the next day, it will reach 30m total before it falls during the night and it will be able to get out of the hole.

Answer:

Step-by-step explanation:

9 bananas 7 mangoes 2 pineapples.  = 18 pieces  of fruit

Fraction of fruit that is pineapple

pineapple / total

2/18

Simplifying

1/9

Answer:

1/9

Step-by-step explanation:

To start off, add all of the known fruit amounts in order to find the total amount of fruit.

9 bananas +7 mangoes + 2 pineapples

When you do this, you find that the total fruit is 18

In order to know probability, you must divide the desirable outcome by the total possible outcomes.

The desirable outcome is pineapple. There are 2 pineapples. The total possible outcomes are 18.

2/18

You can simplify this fraction so that it becomes 1/9 by dividing the numerator and the denominator by 2

Answer:

adult tickets are $8 and student tickets are $14

Step-by-step explanation:

to find the price of adult and student tickets, first look at all the given values:

a = adult tickets

s = student tickets

so: 4a + 5s = 102

and : 7a + 5s = 126

since in both equations the number of student tickets are the same, we have to find the difference of value to determine how much adult tickets are:

126-102 = 24

there are 3 more adult tickets in the equation with a total of 126, therefore:

24 / 3 = 8

that means each adult ticket is work 8 dollars.

now substitute this value:

4(8) + 5s = 102

32 + 5s = 102

you can solve this by concluding that 102- 32 is 70

that means 5(s) has to equal 70

so 70 / 5 = s

70/5 = 14

so the value of s = 14 and the value of a = 8

Answer:

[tex]E(x)=-0.2101[/tex]

Step-by-step explanation:

The expected value for a discrete variable is calculated as:

[tex]E(x)=x_1*p(x_1)+x_2*p(x_2)[/tex]

Where [tex]x_1[/tex] and [tex]x_2[/tex] are the values that the variable can take and [tex]p(x_1)[/tex] and [tex]p(x_2)[/tex] are their respective probabilities.

So, a player can win 2 dollars or looses 1 dollar, it means that [tex]x_1[/tex] is equal to 2 and [tex]x_2[/tex] is equal to -1.

Then, we need to calculated the probability that the player win 2 dollars and the probability that the player loses 1 dollar.

If there are n identical and independent events with a probability p of success and a probability (1-p) of fail, the probability that a events from the n are success are equal to:

[tex]P(a)=nCa*p^a*(1-p)^{n-a}[/tex]

Where [tex]nCa=\frac{n!}{a!(n-a)!}[/tex]

So, in this case, n is number of times that the player tosses a die and p is the probability to get a 6. n is equal to 6 and p is equal to 1/6.

Therefore, the probability  [tex]p(x_1)[/tex] that a player get at least two times number 6, is calculated as:

[tex]p(x_1)=P(x\geq2)=1-P(0)-P(1) \\\\P(0) =6C0*(1/6)^{0}*(5/6)^{6}=0.3349\\P(1)=6C1*(1/6)^{1}*(5/6)^{5}=0.4018\\\\p(x_1)=1-0.3349-0.4018\\p(x_1)=0.2633[/tex]

On the other hand, the probability [tex]p(x_2)[/tex] that a player don't get  at least two times number 6, is calculated as:

[tex]p(x_2)=1-p(x_1)=1-0.2633=0.7367[/tex]

Finally, the expected value of the amount that the player wins is:

[tex]E(x)=x_1*p(x_1)+x_2*p(x_2)\\E(x)=2*(0.2633)+ (-1)*0.7367\\E(x)=-0.2101[/tex]

It means that he can expect to loses 0.2101 dollars.

Answer:

Expected value = -0.2101

Step-by-step explanation :

Givena discrete variable the expected value is given as:

E(x) = xp(x) + yp(y)

Where x and y are the values the variables can assume, and p(x) and p(y) are their respective probabilities.

Probability that a player gets 6 at least twice = p(x ≥ 2) = 1 - p(x≤ 2)

= 1 - p(0) - p(1)

But p(0) = 0.3349

p(1) = 0.4018

p(x ≥ 2) = 1 - 0.3349 - 0.4018

= 0.2633

p(y) = 1 - p(x)

= 1 - 0.2633

= 0.7367

Expected value = 2(0.2633) + (-1)(0.7367)

= -0.2101

A loss of $0.2101 is expected.
