said the bill is 25 and gave them so each gave her $2 for the tip so if each got $1.00 back that means you each paid $9×3=27 plus the $2 .00 tip where did the other $1.00 go

Answer

No missing money

Step-by-step explanation:

Original money given to the waiter = $30

Each person paid $10

The waitress comes back with the waitress comes back and said the bill is $25

They gave her $2 for the tip

if each got $1.00 back

Balance = $1.00 × 3

= $3.00

That means each paid $9×3 = $27 including $2 .00 tip(recall that cost of the meal is now $25 plus $2 tip)

Each of them got $1.00 back

Total money spent = (cost of meal + tip) + balance of $3.00 given to them

= $27 + $3

= $30

Therefore, there is no missing $1.00

The swimming pool at Spring Valley High School is a rectangle with a width of 70 meters and a length of 30 meters. Around the pe
Nadya [2.5K]

The expression for the area of the rectangular swimming pool is given as follows:

A = w² + 100w + 2100.

<h3>What is the area of a rectangle?</h3>

The area of a rectangle of length l and width w is given by the multiplication of these measures, that is:

A = lw.

In this problem, considering the width of 70 meters and a length of 30 meters, plus the floor of w meters, we have that:

  • l = 30 + w.
  • wi = 70 + w.

Hence the area is given as follows:

A = l x wi = (30 + w)(70 + w) = w² + 100w + 2100.

The expression cos^-1 (3/5) has an infinite number of values.. True or False.
Pavel [41]

Answer:

The given statement:

The expression cos^-1 (3/5) has an infinite number of values is a true statement.

Step-by-step explanation:

We are given a expression as:

\arccos (\dfrac{3}{5})

Let us equate this expression to be equal to some angle theta(θ)

i.e.

Let

\arccos (\dfrac{3}{5})=\theta\\\\\cos \theta=\dfrac{3}{5}

As we know that the limit point of the cosine  function is [-1,1]

i.e. it takes the value between -1 to 1 and including them infinite number of times.

Also,

-1< 3/5 <1

This means that the cosine function takes this value infinite number of times.

That is there exist a infinite number of theta(θ) for which:

\cos \theta=\dfrac{3}{5}

i.e. the expression:

\arccos (\dfrac{3}{5}) has infinite number of values.

Seed are often treated with fungicides to protect them in poor draining, wet environments. A small-scale trial, involving five t
Natalija [7]

Answer:

2.38%

Step-by-step explanation:

Given that:

The population size involving numbers of treated and untreated seeds N  = 10

the number of seeds that are treated which are observed = 5

the number of seeds that sprouted 'n' = 4

Now, use the method of hypergeometric probability, we have the formula:

p(y) = \dfrac{(^r_y)(^{N-r}_{n-y})}{(^N_n)}

∴

p(4) = \dfrac{(^5_4)(^{5}_{0})}{(^{10}_4)}

p(4) = \dfrac{\dfrac{5!}{4!(5-4)!}* \dfrac{5!}{0!(5-0)!}  }{\dfrac{10!}{4!(10-4)!} }

p(4) = \dfrac{\dfrac{5!}{4!}* \dfrac{5!}{(5)!}  }{\dfrac{10!}{4!(6)!} }

p(4) = \dfrac{5*1  }{210}

p(4) = 0.0238

p(4) = 2.38%
