Farmer Ben has only ducks and cows. He can’t remember how many of each he has, but he doesn’t need to remember because he knows

he has 22 animals and 22 is also his age. He also knows that the animals have a total of 56 legs, because 56 is also his father’s age.

Answer:

12 cows - 48 legs

4 ducks- 8 legs

- there are many different numbers you can do but if you want to change the numbers and have more ducks then: for every one cow you take away two more ducks.

Step-by-step explanation:

22 total animals

56 total legs

ducks have 2 legs

cows have 4 legs

12 times 4 = 48 ( 12 cows with 4 legs each cow =  48 legs)

4 times 2 = 8 ( 4 ducks with 2 legs each duck = 8 legs)

identify the type i error and the type ii error that corresponds to the given hypothesis. the proportion of people who write wit
djverab [1.8K]

Type I error is:

" Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29 "

Type II error is:

"Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually different from 0.29 "

<u>What is proportion?</u>

An equation in which two ratios are made equal is called a proportion. For instance, you could write the ratio as 1: 3 (for every one boy, there are three girls), which means that 14 of the population is made up of boys and 34 of the population is made up of girls.

In Statistics, a  type I error is the rejection of a true null hypothesis

and  a type II error is the non-rejection of a false null hypothesis

Given that p = 0.29 is accepted

Now type I error is

C. Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29

i.e. (false positive)

and type II error here is

B. Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually different from 0.29.

Answer:

  (c)  Not parallel: corresponding angles are not congruent

Step-by-step explanation:

The two angles shows are both "east" of the respective points of intersection, so are "corresponding" angles. If (and only if) lines r and s are parallel, corresponding angles are congruent. These angles have different measures, so lines r and s are not parallel.

100 POINTS! I REALLY NEED TO GET THIS CORRECT! Factor the quadratic trinomial.
Assoli18 [71]

The factors of the equation x^2-3x-18 are (x-6)(x+3)

Step-by-step explanation:

We need to factor the quadratic trinomial. x^2-3x-18

We will do factorization by braking the middle term such that adding those number we get middle term (-3x) and multiplying those numbers we get (-18x^2)

Solving:

x^2-3x-18\\=x^2-6x+3x-18\\=x(x-6)+3(x-6)\\=(x-6)(x+3)

So, the factors of the equation x^2-3x-18 are (x-6)(x+3)
