Mr. and Mrs. Doran have a genetic history such that the probability that a child being
born to them with a certain trait is 2/5. If they have seven children, what is the
probability that exactly six of their seven children will have that trait? Round your
answer to the nearest thousandth.

Answers

Answer 1

Answer: [tex]0.017[/tex]

Step-by-step explanation:

Given

the Probability that a child will born with a certain trait is [tex]\frac{2}{5}[/tex]

So, the probability that child does not possess that certain trait is [tex]\frac{3}{5}[/tex]

The probability that exactly six of their children has that trait is

[tex]\Rightarrow (\dfrac{2}{5})^6\cdot (\dfrac{3}{5})[/tex]

For 7 children it is

[tex]\Rightarrow 7\times (\dfrac{2}{5})^6\cdot (\dfrac{3}{5})\\\\\Rightarrow 0.017[/tex]

Answer:

0.12 x (x + 3000) = 4200

equation for her salary last year : last year's salary = (4200 / 0.12) - 3000

$32,000

Step-by-step explanation:

Let x = last year's salary

this year's salary = 3000 + x

this equation can be used to determine how much she saved this year = 0.12 x (x + 3000) = 4200

to find last year's salary, make x the subject of the formula

4200 / 0.12 - 3000 = x

x = $32,000

The measure of an angle is 50°.what is the measure of its complementary angle

Answers

Answer:

If "x" is the degree measure of the given angle, then the measure of its complement is (x+50) degrees.

And since these angles are complementary, you have this equation x + 50 = 90 °

x = 90 - 50

x = 40 °

The other angle is 40 °

4 A roll of paper is shown below.

Tube

About how much cardboard is needed to make the inner tube for a roll of paper if the tube

has a diameter of 4.5 cm and is 24 cm long?

F 339 cm2

G 679 cm2

H 371 cm2

J

382 cm2

Answers

Answer:

339 cm²

Step-by-step explanation:

Using the relation for the surface area of a cylinder :

A = 2πrh

r = Radius = diameter / 2 = 4.5 / 2 = 2.25 cm

Height, h = 24 cm

A = 2 * 22/7 * 2.25 * 24

A = 339.29200 cm²

Surface Area =339 cm²

About 339cm³ of cardboard will be needed for the inner tube.

To make inner tube card board needed is 339 cm² of the material.

What is Surface area ?

The surface area of a solid object is a measure of the total area that the surface of the object occupies.

Here, diameter = 4.5 cm

then, radius = 4.5/2 = 2.25 cm

          height = 24 cm

Surface area = 2πrh

                       = 2 X 3.14 X 2.25 X 24

                       = 339.12 cm²

Thus, to make inner tube card board needed is 339 cm² of the material.

Step-by-step explanation:

1) solution

Hypotenous(h)=?

perpendicular(p)=16

base(b)=12

By using formula

h^2 = p^2 + b^2

h^2 = 16^2 + 12^2

h^2 = 256 + 144

h^2 = 400

h^2 = 20^2

h = 20

therefore hypotenous (h) is 20

2) solution

hypotenous = (?)

perpendicular=(77)

base=(36)

by using formula

h^2 =p^2 + b^2

h^2=77^2+ 36^2

h^2=5929+1296

h^2=7225

h^2=85^2

h=85

therefore hypotenous (h) is 85

Therefore , the solution to the given problem of surface area comes out to be 24 square unit.

What does surface area is exactly?

Shape is a unit used to describe how much overall space a material's surface occupies. A three-dimensional shape surface area is equal to the sum of its surroundings. The overall surface coverage of a multi shape is referred to as surface area. The volume of water of a cube featuring five rectangular faces can be calculated by adding up each face's specific area. As an alternative, you can identify the box's measurements using the formula below: Surface (SA) is equal to two times two times two. 

Here,

The presented parallelogram has a height of 5-2 = 3 units.

The given parallelogram's basis is comprised of => 7 -(-1) units => 8 units.

As a result, the supplied parallelogram has a surface area of 8 * 3 = 24 square units.

As a result, 24 square units are required to solve the given area problem.

Which function has a greater y-intercept?

Answers

Answer:

Option C, both functions have an y-intersect equal to 2.

Step-by-step explanation:

When we have a function f(x), the y-intercept is the value f(0). This is the point where the graph of the function intersects the y-axis.

Then, for f(x) = -x^2 + 5*x + 2

The y-intercept is:

f(0) = -0^2 + 5*0 + 2 = 2

f(0) = 2

And for g(x) we do not have the equation, but we have the graph, so we can just look at which value of y does the graph intersects the y-axis.

We can see that the graph intersects the graph at y = 2

Then the y-intersect is: g(0) = 2

So both functions have the same y-intersect. Then the correct option is C.

Un industrial obtiene un préstamo de $ 15.000, al 23% anual por el lapso de 5 años. Calcular el monto a la finalización de este tiempo

Answers

Answer:

$18,781.5

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

Loan amount (P) = $15,000

Rate of interest (r) = 23%

Time (t) = 5 years

Let this loan is compounding annually, then the amount after 5 years can be calculated as follows,

Final amount = P  [tex](1 + ( r/t))^{t}[/tex]

by putting the value in formula, we get

= $15,000 (  [tex](1 + ( 0.23/5))^{5}[/tex]

= $15,000 × 1.2521

= $18,781.5

At your local store, you are given a coupon for 20% off any store item purchased on Monday. When you return to your store, you notice that an item (normal price = $50) is on clearance for 40% off. You are allowed to use the coupon on the clearance item. How much should you pay for the item? Should it be 60% off of the normal price?

Answers

Answer:

$24

no, it is 48% off normal price

Step-by-step explanation:

clearance price = normal price - value of the 40% discount

value of the 40% discount = 0.4 x $50 = $20

Price = $50 - $20 = $30

final price = clearance price - value of 20% coupon

value of 20% coupon = 0.2 x $30 = $6

final price = $30 = $6 = $24

total value off normal price = $24 /$50 x 100 = 48%

54

Step-by-step explanation:

3*6*3=54

The solution is Option G.

The number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt is given by combination C = 54 ways

What are Combinations?

The number of ways of selecting r objects from n unlike objects is:

ⁿCₓ = n! / ( ( n - x )! x! )

where

n = total number of objects

x = number of choosing objects from the set

Given data ,

Let the number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt be C

Now , the equation will be

The total number of shoes = 3 pairs

The total number of pants = 3 pairs

The total number of shirts = 6 shirts

And , the number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt  is calculated by Combination , where

The number of ways of selecting 1 pair of shoes = ³C₁

The number of ways of selecting 1 pair of pants = ³C₁

The number of ways of selecting 1 shirt = ⁶C₁

So , the total number of ways = ³C₁ x ³C₁ x ⁶C₁

On simplifying the equation , we get

The total number of ways C = 3 x 3 x 6

The total number of ways C = 54 ways

Hence , the combination is C = 54 ways

Answer:

Step-by-step explanation:

Make a chart:

1 adult + 7 children = 1(5)+7(3) = 26

2 adults + 6 children = 2(5)+6(3) = 28

3 adults + 5 children = 3(5)+5(3) = 30

4 adults + 4 children = 4(5)+4(3) = 32

5 adults + 3 children = 5(5)+3(3) = 34

6 adults + 2 children = 6(5)+2(3) = 36

7 adults + 1 child = 7(5)+1(3) = 38

The answer in bold is the only one that leads to $30, therefore he bought 3 adult tickets and 5 children tickets.
