Answer:

0.65

Step-by-step explanation:

The probability that a randomly selected student is in sports is 0.65.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

Given that, the number of students = 100.

Total number of outcomes =100

Number of favorable outcomes =65

Now, P(Sports) = 65/100

= 0.65

The probability that a randomly selected student is in sports is 0.65.

Answer:

The total cost is 26.6 dollars

Step-by-step explanation:

Given

The total bill of the breakfast = $ 21.60

Sales tax = 7% of the total bill value

Total bill after adding the 7% sales tax

$ 21.60 + 7% of $ 21.60

[tex]21.60 + \frac{7}{100} * 21.60\\21.60 + 1.512\\23.112[/tex]dollars

After adding 15% of the tip values to the payable amount of $ 23.112, the total bill becomes

$ 23.112 + 15% of $ 23.112

[tex]23.112 + 3.4668 = 26.5788[/tex]

The total cost is 26.6 dollars

Answer:

1.) 12000

2.) 6750

3.) 2.41

Step-by-step explanation:

Given the Equation :

f(t)=12,000(3/4)^t. ; where, t = time ; f(t) = worth of car at time, t

When, car was purchased, t = 0

t = 0

f(0) = 12000(3/4)^0

= 12000 * 1

= 12000

2.)

f(2) ; this mean the worth of the car after 2 years :

f(2)=12,000(3/4)^t.

12000(3/4)^2

12000 * 0.5625

= 6750

When car will be worth 6000

f(t) = 6000

f(t)=12,000(3/4)^t.

6000 = 12,000(3/4)^t

6000 / 12000 = (3/4)^t

1/2 = (3/4)^t

Take the log of both sides :

Log(0.5) = log(0.75)^t

log(0.5) = tlog(0.75)

- 0.301029 = - 0.124938t

t = - 0.301029 / - 0.124938

t = 2.4094

t = 2.41 years

Answer:

b= 16√15 or 23

Step-by-step explanation:

Input your values into the Pythagorean theorem.

c^2=a^2+b^2

576=36+b^2

b=√540

b=16√15 or 23

multiply by 8 on both sides

(20)8 - 8(4b/8) = (18)8

160 - 4b = 144

subtract 160 on both sides

160 - 160 - 4b = 144 - 160

-4b = -16

divide by -4 on both sides

-4b/-4 = -16/-4

b = 4

Answer:

...............

Step-by-step explanation:

...............

Answer:

Solution given:

diameter [d]=16m

radius [r]=8m

let slant height =l

surface area =628.32m²

πr(r+l)=628.32m²

π×8(8+l)=628.32

8+l=628.32/(8π)

8+l=25

l=25-8

l=17m

now

height of cone [h]=√{17²-8²}=15m

Again

Volume of cone =⅓πr²h=⅓×π×8²×15=320π 0r 1005.31m³

The required volume is 320π 0r 1005.31m³

The Volume of the given Cone is: 1005.469 cubic. cm.

V=1005.469 cubic. cm.

The volume of a 3 -dimensional solid is the amount of space it occupies.

The volume V of a cone with radius r is one-third the area of the base B times the height h .

V= [tex]\frac{1}{3} \pi r^{2} h[/tex]

Surface area of cone= 628.32

[tex]\pi r(l+r)[/tex]= 628.32

3.14 x 8 (l + 8)= 628.32

l+8= 25.01

l= 17.01 cm

height= 15.01 cm

Now volume of cone,

V= [tex]\frac{1}{3} \pi r^{2} h[/tex]

  = [tex]\frac{1}{3} *3.14 *8^{2}* 15.01[/tex]

  =1005.469 cubic. cm.

volume of cone, V= 1005.469 cubic. cm.

Answer:

A=30

Step-by-step explanation:

Set your equation up as following:

180=90+(x+37)+(x+67)

180=90+37+67+2x

180-90-37-67=2x

-14=2x

-14/2=x

-7=x

Angle A = x+37

A=-7+37

A=30

Answer:

m<A = 30

Step-by-step explanation:

The right square is a 90 degree angle

All angles in a triangle add up to 180 so:

x + 37 + x + 67 + 90 = 180

2x + 194 = 180

2x = 180 - 194

2x = -14

x = -7

Answer:

Second.

Step-by-step explanation:

A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

Answer:

x = 16

Step-by-step explanation:

The two angles are vertical angles

Vertical angles are congruent

That being said we can create an equation

4x - 7 = 3x + 9

now we solve for x

step 1 add 7 to each side

9 + 7 = 16

-7 + 7 cancels out

now we have 4x = 3x + 16

step 2 subtract 3x from each side

4x - 3x = x

3x - 3x cancels out

we're left with x = 16
