Answer:

Of the 600 elephants that he observes in random places in the reserve, he counts \frac{8}{30}(600)=160 elephants with broken tusks.

Step-by-step explanation:

Let x denotes number of elephants having broken tusks out of 600 elephants.

Of the 30 elephants that he observes in random places in the reserve, he counts 8 elephants with broken tusks.

So,

Of the 1 elephants that he observes in random places in the reserve, he counts \frac{8}{30} elephants with broken tusks.

Therefore,

Of the 600 elephants that he observes in random places in the reserve, he counts \frac{8}{30}(600)=160 elephants with broken tusks.

Find the value of x that makes line m ll n
guapka [62]

Answer:

See below ↓

Step-by-step explanation:

14.

  • Between two lines m ║ n, the ∦ cuts through them forming two angles
  • As it forms a line, the sum of the angles is 180°
  • 3x + 47 + x + 7 = 180
  • 4x + 54 = 180
  • 4x = 126
  • x = 126/4 = 63/2 = 31.5

15.

  • Alternate exterior angles on a transversal are equal
  • 5x = 2x + 78
  • 3x = 78
  • x = 26

I need help!<br> What is the value of t?
Nezavi [6.7K]
The t-value measures the size of the difference relative to the variation in your sample data. Put another way, T is simply the calculated difference represented in units of standard error. The greater the magnitude of T, the greater the evidence against the null hypothesis.
