What is the probability of selecting a boy or a blonde-haired person from 12 girls, 5 of whom have blonde-haired and 15 boys, 6 of whom have blonde-haired

Answers

Answer: 20/27

Step-by-step explanation:

So it is non- mutually exclusive;

Let B for the boys and H for the blond hair.

P(B) = 15/27; P(H) 11/27; P(B and H) = 6/27

Then, we have,

P(B or H) = 15/27 + 11/27 - 6/27

P(B or H) = 20/27 

Therefore,  the probability of selecting a boy or a blond-haired person is 20/27.

Tom can do a job in 4 hours while Sam can do it in 6 hours. How many hours would it take to complete this job if they work together?

Answers

Answer:

12/5hours=2.4 hours

Step-by-step explanation:

Sam:6hours

Tom:4hours

This is a rate problem

Sam's rate is one job completed in 6 hours which is 1/6

Tom's rate is one job completed in 4 hours which is 1/4

Together, they could complete 1/4+1/6 of the job in y hours

We are trying to find the rate at which Sam and Tom could complete the job together, or one job in x days, for a rate of 1/y

1/4+1/6=1/y

The least common denominator is 12y

Multiplying through by the LCD which gives:

12y(1/4)+ 12y (1/6)= 12y (1/y)

3y + 2y=12

5y = 12

y=12/5 hours=2.4hours

Therefore it will take 12/5 hours or 2.4 hours to complete the job if they work together

the shapes below are drawn on a centimeter grid, show that the triangle and the square have the same area.

Answers

Answer:

Area_square = 4 cm2

Area_triangle = 4 cm2

Step-by-step explanation:

The first thing to do is calculate the area of both figures.

The area of the square is given by:

Area_square = side * side

The side of the square is 2 cm, so:

Area_square = 2 * 2 = 4 cm2

The area of the triangle is given by:

Area_triangle = base * height / 2

The base is 2 cm, and the height is 4 cm, so we have:

Area_triangle = 2 * 4 / 2 = 4 cm2

So we have that Area_square = Area_triangle = 4 cm2

The amount of money that Tom had in his pension fund n 2016 was E55 000. Dis plans involve him putting $8 200 in his fund every year for the next 15 years. How much will Tom have in the pension fund in 2031?

You have $10,000 to invest, and three different funds from which to choose. The municipal bond fund has a 7% return, the local bank's CDs have an 8% return, and the high‐risk account has an expected (hoped‐for) 12% return. To minimize risk, you decide not to invest any more than $2,000 in the high‐risk account. For tax reasons, you need to invest at least three times as much in the municipal bonds as in the bank CDs. Assuming the year‐end yields are as expected, what are the optimal investment amounts?

Answers

Answer:

Optimal investment amount = $300

Step-by-step explanation:

discount = x

original price = 10,000

discount% = 7%

x/10,000 = 7/100

x · 100 = 7 · 10,000

100x = 70,000

100x/100 = 70,000/100

x = 700

discount = x

original price = 10,000

discount% = 8%

x/10,000 = 8/100

x · 100 = 8 · 10,000

100x = 80,000

100x/100 = 80,000/100

x = 800

discount = x

original price = 10,000

discount% = 12%

x/10,000 = 12/100

x · 100 = 12 · 10,000

100x = 120,000

100x/100 = 120,000/100

x = 1,200

So:

$1,200 - $800 - $700 = $300

We max out the high return investment, $2000 for 12%.

We have $8000 left to invest and we want to put as much in CDs at 8% as possible.  Let's call b the bond investment and c the CD investment.  We have

b ≥ 3c

Since munis have the lower return we want as many CDs as possible.  So we choose:

b = 3c

b + c = 8000

3c + c = 8000

4c = 8000

c = 2000

That leaves b=3c=6000 for bonds.

Answer: $6000 in bonds, $2000 in CDs, $2000 in high-risk.

Notice that it is at least.

So He can do sessions from 3 , 4, 5, 6 up to 7 nights per week

Two triangles are congruent if two angles and the included side of one triangle are equal to two angles and the included side of the other triangle.

Check whether the triangles are congruent :

The given triangles are both right angled triangles.

The side 12 units is the included side between the angles 45° and 90° in both the triangles. This is the required condition for ASA congruence rule.

Cam is making a party hat, shown at left, in the shape of a cone for his
birthday. The circumference of the part of his head where the hat will
rest is 56 centimeters (cm). If the height of the hat is 25 cm, which of
the following is closest to the volume of Cam's hat, measured in cubic
centimeters (cm)?

Answers

Answer:

V≈2,080cm^3  Hope I helped :)

Step-by-step explanation:

The volume of a cone of radius r and height h is:

V=1/3πr^2h

Since the circumference of Cam's head is 56

2πr=56

r=56/2π

r=28/π

The volume of the hat is therefore:

​V=1/3π(28/π )^2(25)

V=1/3((28)^2/π)(25)

V=1/3(19,600/π)

V≈2,080cm^3

 

The volume of the Cam's hat measured in cubic centimetres is 2081 cm³

Volume of a cone:

The volume of a cone is as follows:

v =  1 / 3 π r²h

where

h = height

r = radius

The circumference of the part of his head where the hat will rest is 56 cm. Let's find the radius

circumference = 2πr56 = 2 × π × rr = 28 / π

h = 25 cm

V =  1 /  3 × π × (28 / π )² × 25

V =  1 / 3 × π × 784 / π² × 25

V = 19600 / 3π

V = 19600 / 9.42

V = 2080.67940552

V ≈ 2081 cm³

b. 29.890
c. 29.820
d. 29.800
e. 29.840

Answers

Answer:

e. 29.840

Step-by-step explanation:

The cat, the floor and the foot pole form the shape of a right angled triangle.

The opposite is the height of the foot pole = 32 ft

The adjacent is the distance of the cat from the base of the foot pole.

The hypotenuse is the direct distance of the cat from the bird.

The angle of elevation, x, is 47°

To find the distance of the cat from the foot of the foot pole, we can use to TAN part of the trigonometric function SOHCAHTOA:

tan(x) = opposite / adjacent

=> tan(47) = 32 / adj

adj = 32 / tan(47)

adj = 29.840 ft

Therefore, the cat is 29.840 feet from the base of the foot pole.

Answers

Answer:

(x+5)²(x²+5)

Step-by-step explanation:

Given two functions x²+5 and x²+10x+25, to get their Lowest common factor, we need to to first factorize x²+10x+25

On factorising we have:

x²+5x+5x+25

= x(x+5) +5(x+5

= (x+5)(x+5)

= (x+5)²

The LCM can be calculated as thus

| x²+5, (x+5)²

x+5| x²+5, (x+5)

x+5| x²+5, 1

x²+5| 1, 1

The factors of both equation are x+5 × x+5 × x²+5

The LCM will be the product of the three functions i.e

(x+5)²(x²+5)

This hives the required expression.
