Parker spent 1/3 of his money on a sweater. He spent 3/5 of the remainder on a pair of jeans. If he has $36 left, how much did t
LenaWriter [7]
Sweater: 1/3 = 0,333
Jeans: 3/5 = 0,6

1 – 0,6 – 0,333 = 0,067

So the 36$ represents 6,7% of all the money he had at first. (just for you to know 1 represents 100% of the money he had)

Now, you just have to use the rule of three
0,067 = 36
0,333 = x

(0,333•36)/0,067= 179,1$
The sweater costed 179,1$

A newsletter publisher believes that below 68% of their readers own a Rolls Royce. Step 1 of 1 :State the null and alternative h
Vanyuwa [196]

The null hypothesis is p = 0.68 while the alternative hypothesis will be that it's below that is p < 0.68.

First, let us understand the Null and Alternative hypotheses:

The null hypothesis is simply to predict that there is no effect of the relationship between the variables.

The alternative hypothesis is to state the research prediction of a relationship or effect. In this case, the newsletter publisher believes that below 68% of their readers own a Rolls Royce.

The null hypothesis is that the proportion of readers who own a Rolls Royce is equal to 0.68.

Null hypotheses = H₀: p = 0.68

The alternate hypothesis is that the proportion of readers who own a Rolls Royce is below 0.68.

Alternate hypotheses = H₁: p < 0.68.

Thus, the null hypothesis is p = 0.68 while the alternative hypothesis will be that it's below that is p < 0.68.

Jimmy and Tony observed two points, P and Q, on a number line. A number line is shown from negative 1 to positive 1 with increme
Ira Lisetskai [31]
P is 5 ticks to the left of 0, so it would be -5/8

Q is 5 ticks to the right of 0, so it would be at 5/8

 an absolute value turns a negative number into a positive number
 so absolute value of  P located at -5/8 = 5/8
 this is the location of point Q

<span>Jimmy said that the absolute values of the numbers represented by the two points are the same. 
</span>
so Jimmy is correct
