Answer:

230 were sold at the door

170 were sold in advance

Step-by-step explanation:

*i dont know if this is the proper way to do it but it has the correct answer

x=at door y=in advance

x+y=400

3x+2y=1030

y=-x+400

2y=-3x+1030

y=-3/2x+515

-x+400=-3/2x+515

x=230 y=170

Answer:

An exponential has the base at the bottom, or the lower portion. Think of "basement" to help remember this. The exponent is the number up top, so 12 is the exponent

therefore, the correct answer is 11

In the diagram at the left, O is the center of the circle, MNOP is a rectangle, and the area of the circle is 100π. What is the
RUDIKE [14]

The length of the diagonal of the rectangle will be 14.142 units.

<h3>What exactly is a rectangle?</h3>

It has four sides and is a polygon. The internal angle total is 360 degrees. The opposing sides of a rectangle are parallel and equal, and each angle is 90 degrees.

Rectangle diagonals are equally equal and meet at the midpoint.

O is the circle's center, MNOP is its rectangle, and the circle's area is 100 in the diagram to the left.

Area of circle=πr²

100 π= πr²

r= 10 units

The length of the rectangle is equal to the radius of the circle is 10 units. The length of the diagonal is √2  times the side of the rectangle;

L=√2 R

L=1.414×10

L=14.14

Hence the length of the diagonal of the rectangle will be 14.142 units.

Silk scarves are produced in a factory. Quality control investigations find that 0.5% of the scarves produced have flaws, which
Goshia [24]

The binomial probability is determined by the formula

\begin{gathered} P_x=\binom{n}{x}p^xq^{n-x} \\ \text{where} \\ P\text{ is the binomial probability} \\ x\text{ is the number of times for a specific outcome within }n\text{ trials} \\ p\text{ is the probability of success on a single trial} \\ q\text{ is the probability of failure on a single trial} \\ n\text{ is the number of trials} \end{gathered}

Here, we will assume that finding the flaw is the "success" of the trial hence the following given

\begin{gathered} p=0.05 \\ q=0.95 \\ n=30 \end{gathered}

Finding the probability of one flawed scarf

\begin{gathered} P(X=1)=\binom{30}{1}(0.05)^1(0.95)^{30-1} \\ P(X=1)=0.3389 \end{gathered}

Finding the probability of no flawed scarves

\begin{gathered} P(X=0)=\binom{30}{0}(0.05)^0(0.95)^{30-0} \\ P(X=0)=0.2146 \end{gathered}

Finding the probability of more then three flawed scarves

\begin{gathered} P(X>3)=1-P(X\le3) \\ P(X>3)=1-0.93922843869 \\ P(X>3)=0.0608 \end{gathered}
