Answer:

I'm glad you asked!I couldn't fully understand it so I made it the best of my ability.

Step-by-step explanation:

1.(Please,I cannot understand it .I think it is incomplete.)

2.18 out of 270 students speak 3 languages or more.So 30,330 x \frac{18}{270} = 2,002.2,002 students.

3.We would do 5,000 x \frac{2}{10} = 1,000.

4.No, the manufacturer cannot assume the prediction is valid.

The sample size of 10 is too small compared to the size of the shipment.

5.You can use random samples by using them for graphs which numbers are too big.

I think you can multiply how many are defective in a sample by how much more stuff there is

I am Lyosha [343]

Answer:

238.40

Step-by-step explanation:

you need to use "PRT"( Principal× Rate×time) but since it doesn't give us the time, we'll be only doing principal×rate. just multiply 596 and 40% And don't forget to put the percent sign bc it would change the price!! and I hope that helps u

12) Find mZVUT if mZVUT = 10x +9,<br> m_BUT = 7x - 1, and mZVUB= 37º.
Mariulka [41]

Answer:

99°

Step-by-step explanation:

  • m∠VUT = 10x + 9
  • m∠BUT = 7x - 1
  • m∠VUB = 37°
  • m∠VUT = ?

<u>We see that</u>

  • m∠VUT = m∠BUT + m∠VUT
  • 10x + 9 = 7x - 1 + 37
  • 10x - 7x = 36 - 9
  • 3x = 27
  • x = 9

<u>Angle VUT measures:</u>

  • 10x + 9 = 10*9 + 9 = 99°
