Gennadij [26K]3 years ago
6 0

Answer:

x = -1

Step-by-step explanation:

The vertex is halfway between the focus and the directrix.

So here the directrix is  a vertical line  to the left of the vertex and passing through the point (2-3, 9) = (-1, 9)

It is x = -1.

Use the row of numbers shown below to generate 12 random numbers between 01 and 99.
sattari [20]

Answer:

Below is the complete step-by-step explanation.

Step-by-step explanation:

Given the row of numbers

25060 12315 86244 97348 36173 32710 80033 16160

<u>Taking 25060 as seed</u>

Total random numbers to be generates = 12

Range of random number generators

  • Minimum value = 01
  • Maximum Value = 99

Seed the number (25060) into your calculator. 25060 ➡️ rand

So, the operation randInt(1,99,12) will generate the following 12 random numbers between 01 and 99.

85 90 62 45 26 97 40 55 67 17 10 32

<u>Taking 12315 as seed</u>

Total random numbers to be generates = 12

Range of random number generators

  • Minimum value = 01
  • Maximum Value = 99

Seed the number (12315) into your calculator. 12315 ➡️ rand

So, the operation randInt(1,99,12) will generate the following 12 random numbers between 01 and 99.

Dots sells T-shirts ($3) and shorts ($7). In April, total sales were $520. People bought 2 times as many T-shirts as shorts. How
timofeeve [1]

Let's assume

number of shorts is x

we are given

People bought 2 times as many T-shirts as shorts

so, number of T-shirts is 2*x=2x

Dots sells T-shirts ($3) and shorts ($7)

so, total price of T-shirts =3*2x

so, total price of shorts =7x

now, we are given

total sales were $520

so,

total price of T-shirts+total price of shorts = total sales

we will get equation

3*2x+7x=520

now, we can solve for x

13x=520

x=40

so,

number of shorts is 40

number of T-shirts is 2*40=80............Answer
