Ok, so:

To do this problem, first, we assign variables.

Let x be the smaps that Many collected.

If Margie collegted 4 times as many stamps as Sam, Margie collected 4x stamps.

Then, we know that both of them have 210.

So x + 4x = 210.

Solving the equation:

5x = 210

And x = 42.

Many collected 42 stamps.

Now, we use the last fact to find how many stamps Margie collected.

Margie collected 4x stamps, that is 4(42), which is equal to 168 stamps.

Margie collected 168 stamps.

Feliz [49]

Answer:

The researcher should use correlation analysis for his studies.

Step-by-step explanation:

What is correlation?

Correlation is a statistical tool used to quantify the degree to which two variables are related. Through the correlation analysis, you evaluate correlation coefficient that tells you how much one variable changes when the other one does. Correlation analysis provides you with a linear relationship between two.

Types of correlation

1. Positive, Negative or Zero Correlation:

2. Linear or Curvilinear Correlation:

3. Scatter Diagram Method:

4. Pearson's Product Moment

Coefficient of Correlation:

5. Spearman's Rank Correlation

Juli buys a flat with 48 flowers. She was wants to plant them in equal rows of 5 flowers. How many rows can Juli plant? How many
miss Akunina [59]

Answer:

5 row, 3 left

Step-by-step explanation:

She has 48 flowers, 5 flowers one row

How many rows can she make? So divide

48/ 5

= 9.6

So she can only make 9 rows

The leftovers flowers are the flowers that didn't manage to make 5 per row

Therefore, if she can make 9 rows, in other words 9 x 5 = 45

45 flowers were able to be placed in a sequence of 5 per row

So the ones that are left is

48 - 45

= 3

A line passes through the point -10,9 and has a slope of 1/2. Write an equation in slope-intercept form for this line
vitfil [10]

Answer:

Step-by-step explanation:

The slope intercept form of an equation of a line is y = mx + b, where m is the slope and b is the y-intercept (the value of y when x=0).

Since the slope is (1/2), we can write:

y = (1/2)x + b

We want a value of b such that it forces the line to go through point (-10,9).  Enter that point in the equation and solve for b:

y = (1/2)x + b

9 = (1/2)*(-10) + b

9 = -5 + b

b = 14

The eqyuation of a line with a slope of (1/2) and goes through point (-10,9) is:

y = (1/2)x + 14

What is the quotient StartFraction 15 p Superscript negative 4 Baseline q Superscript negative 6 Baseline Over negative 20 p Sup
zhannawk [14.2K]

Answer:

- \frac{3}{4} \times  \frac{p^{8} }{q^{3} }

Step-by-step explanation:

We have to find the quotient of the following division, \frac{15p^{-4}q^{-6} }{- 20p^{-12} q^{-3}}.

Now, \frac{15p^{-4}q^{-6} }{- 20p^{-12} q^{-3}}

= - \frac{3}{4} p^{[- 4 - (- 12)]} q^{[-6 - (- 3)]} {Since all the terms in the expression are in product form, so we can treat them separately}

{Since we know the property of exponent as \frac{a^{b} }{a^{c} } = a^{(b - c)}}

= - \frac{3}{4} p^{8} q^{-3}

= - \frac{3}{4} \times  \frac{p^{8} }{q^{3} } (Answer)

{Since we know, a^{-b} = \frac{1}{a^{b} }}
