Answer:

Third angle is $130-7x$

Step-by-step explanation:

We have sum of angles is $180^{0}$

Let the third angle be $y$

Hence

$5x+20+2x+30+y=180\\\\y=130-7x$

Third angle is $130-7x$

A 90 pound object on earth weighs 15 pounds on the moon if an object weighs 156 pounds on earth how much is a win the moon

Tanya [424]

26 pounds

Because

E is the objects gravity in earth
M objects gravity on moon

E=km
Or
90=15k

90/15=15k/15

6=k

156=6m

156/6 =6m/6

26=m

The spinner for a board game has eight colors the arrow can land on. What are the degrees of freedom for a goodness-of-fit test

Juliette [100K]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Number of colors that the arrow can land on = 8

We need to find the degrees of freedom for a goodness of fit test of the fairness of this spinner.

As we know that degree of freedom is 1 less than the size of sample.

So, Mathematically, it is expressed as below:

So, Degree of freedom would be

$v=n-1\\\\v=8-1\\\\v=7$

Hence, Option 'c' is correct.
