A kid at the bus stop is tossing a coin. He tosses the coin 19 times and it lands on heads eight times. If the kid tosses the coin an 20th time, what is the probability that it will land on heads?

Answer:

x=114 i believe

Step-by-step explanation:

x+66=180

subtract 66 from 180,which gives you 114

1/4x - 5 = 10 -x

Add 5 to both sides:

1/4x = 15 -x

Add x to both sides:

1 1/4x = 15

Divide both sides by 1 1/4:

x = 12

(1/4)x - 5 = 10 - x

x/4 - 5 = 10 - x

(x/4)(4) - 5(4) = 10(4) - 4x

x - 20 = 40 - 4x

x + 4x = 40 + 20

5x = 60

x = 60/5

x = 12

The equation that can be solved to find the number of nails in each box =

5x = 460

The number of nails in each box = 92 nails

Step-by-step explanation:

A carpenter bought 5 identical boxes of nails. She used 25 nails for a project and now has 435 nails left. Which equation can be solved to find the number of nails in each box.

Let the number of nails in each box be represented by x

Therefore our Equation =

5x = 25 + 435

5x = 460

Solving for x

5x/5 = 460/5

x = 92 nails

Therefore, the number of nails in each box = 92 nails

Answer:

It would last for 3.2 days.

Step-by-step explanation:

100 men = 8 days

Answer:

the principal and the amount is 1,800 and 13,800 respectively

Step-by-step explanation:

The computation of the simple interest and amount for the end of the 3rd year is shown below:

Simple interest is

= Principal × rate of interest × time period

= 12,000 × 5% × 3 years

= 1,800

Now the amount is

= 12,000 + 1,800

= 13,800

hence, the principal and the amount is 1,800 and 13,800 respectively

Answer:

25% increase

Step-by-step explanation:

Just do 250000/200000 you will find 1.25

And the one is the base 200000 and convert .25 to percentage, which is 25%

Brainliest maybe?

Answer:

25% or .25

Step-by-step explanation:

fist find the number it increased by minus 250000 from 200000

250000 - 200000 = 50000

then divide the increase by the original

50000/200000 = .25 or 25%

Answer:

40 people came to the Center to hike

Step-by-step explanation:

30 people took classes

22 did bird watching

12 did both

to solve, take 12 and subtract it from each one:

⇒ 30 - 12 = 18

⇒ 22 - 12 = 10

18 people only took classes

10 people only did bird watching

12 people did both

18 + 10 + 12 = 40

Answer:

(a) Leann is incorrect

(b) For every main dish, there are 3 sides

(c) 6 selections

Step-by-step explanation:

See attachment for complete question

Given

Main Dish: Burger (B), Chicken (C), Pasta (P)

Sides: Apple (A), Fries (F)

Solving (a): Is Leann list correct?

From the question, the list is: BA, BF, CA, CF, PA, PF, AB, FB, AC, FC, AP, FP

This list is incorrect because:

AB is the same BA, BF is the same as FB and so on

Solving (b): Number of sides for each Main dish

From the question:

[tex]Main\ dish = 2[/tex]

[tex]Sides = 3[/tex]

This implies that:

For every main dish, there are 3 sides

Solving (c): Total number of selection

In (b), we have:

[tex]Main\ dish = 2[/tex]

[tex]Sides = 3[/tex]

So: the total is:

[tex]Total = Main\ dish * Sides[/tex]

[tex]Total = 2 * 3[/tex]

[tex]Total = 6[/tex]

Answer:

The answer to your problem should be 2

Answer:

x^2 - 6x + 8 = x^2 - 2x - 4x + 8 = x(x-2) - 4(x-2) = (x-4) (x-2)

x - 4 = 0 => x = 4

x - 2 = 0 => x = 2

The fraction form of the expression is -1/7776.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

[tex](-1/6)^5[/tex]

This can be simplified as,

= [tex]\frac{(-1)^5}{6^5}[/tex]

= -1/7776

Thus,

The fraction form of the expression is -1/7776.
