Twenty different statistics students are randomly selected. For each of​ them, their body temperature ​(​C) is measured and their head circumference​ (cm) is measured. If it is found that r​0, does that indicate that there is no association between these two​ variables? Choose the correct answer below. A. ​No, because if r​0, the variables are in a perfect linear relationship. B. ​No, because while there is no linear​ correlation, there may be a relationship that is not linear. C. ​No, because r does not measure the strength of the​ relationship, only its direction. D. ​Yes, because if r​0, the variables are completely unrelated.

Answer:

-1

Step-by-step explanation:

The change in y between x=-1 and x=2 is -3 and -3/3=-1 so the slope is -1

Answer:

-1

Step-by-step explanation:

Use any 2 points on the line.

Let's use (10, -6) and (2, 2).

slope = (difference in y)/(difference in x)

slope = (-6 - 2)/(10 - 2)

slope = -8/8

slope = -1

Answer:

80%

Step-by-step explanation:

Step 1: Add the given data

588 + 147 = 735

Step 2: Divide the number of students who bought a school shirt by the total number of students

588 ÷ 735

= [tex]\frac{735}{588}[/tex]

= 0.8

Step 3: Convert the decimal to fraction

0.8 = 80% (Move the zero 1 place behind the number and remove the ".")

Or

0.8 × 100 = 80%

Therefore, 80% of students bought a school shirt.

Answer:

The annual interest rate is 6%

Step-by-step explanation:

Use the formula for simple interest:  i = prt.

Set i = prt equal to $30:  $30 = prt

Solve this for r:

         $30

r = -------------- = ($30) / ($500)  = 0.06

      $250(2)

The annual interest rate is 6%

Answer:

B)

Step-by-step explanation:

we are given a logarithmic expression

we want to expand it

in order to do so we can consider using

recall that,

[tex] \displaystyle \sqrt{x} = {x}^{ \frac{1}{2} } [/tex]

thus rewrite

[tex] \displaystyle \log_{ \sigma} \bigg( \frac{57}{74} \bigg) ^{ \large\frac{1}{2} } [/tex]

use division logarithm property

[tex] \displaystyle \log_{ \sigma}(57) ^{ \large\frac{1}{2} } - \log_{ \sigma}(74)^{ \large \frac{1}{2} } [/tex]

use exponent logarithm property:

[tex] \displaystyle \frac{1}{2} \log_{ \sigma}(57) ^{ \large } - \frac{1}{2} \log_{ \sigma}(74)^{ \large } [/tex]

and we are done!

Answer: 3, 4, 6

Step-by-step explanation: equilateral triangle, square, regular hexagon

In a regular tessellation 3,4,6 sides can be tessellating regular

polygon.

A normal tessellation is one made the use of only one regular polygon. A semi-normal tessellation uses or extra ordinary polygons. Triangles and squares, for example, shape ordinary tessellations and octagons and squares for a semi-normal tessellation.

First of all, there are handiest 3 normal tessellations which can be triangles, squares, and hexagons. To make a ordinary tessellation, the inner angle of the polygon has to be a diviser. that is due to the fact the angles need to be introduced as much as so it does now not leave any gaps.

A polygon having identical facets of identical lengths are known as everyday polygons. A ordinary polygon is a polygon that is equiangular i.e. all the angles are equal in measure and equilateral i.e. all facets have the equal length.

A line of symmetry is a line that can be attracted to divide a parent into same halves. A determine has line symmetry or reflection symmetry while it could be divided into identical halves that match. A discern has mirrored image symmetry if it could be meditated throughout a line and look exactly the same as it did earlier than the reflection.

Answer:

The area is multiplied by 9

Step-by-step explanation:

Since the area of a kite is the two diagonals multiplied together and then divided by two (turn the kite into two triangles if you don't believe me), then the change in area would be from x*y/2 to 3x*3y/2, which is the same as 9x*y/2, i.e. nine times the original area.

The correct answer:  The area is multiplied by 9.

Midpoint is[tex](-25.15,10.2)[/tex]

Step-by-step explanation:

A line segment refers to line that has two endpoints.

Let [tex](a,b),(c,d)[/tex] be the endpoints of a line segment.

Midpoint of the line segment is given by [tex](\frac{a+c}{2} ,\frac{b+d}{2})[/tex]

Take the given points as follows:

[tex](a,b)=(-24.6,38.1)\\(c,d)=(-25.7,-17.7)[/tex]

Midpoint of a line segment [tex]=(\frac{-24.6-25.7}{2},\frac{28.1-17.7}{2})[/tex]

[tex]=(\frac{-50.3}{2} ,\frac{20.4}{2} )\\=(-25.15,10.2)[/tex]

Answer:

for number 5 Subtract 18 from both sides of the equation

4+18−18=30−18

for number 1 Subtract 7 from both sides of the equation

so number 3 subtract 3 from each side and so on hope it helps

im not sure how to explain it but--

for example.. the first one

1) y + 7 = 12

first, you subtract 7 from both sides

so-- you'll subtract 7-7 on the left and 12-7 from the right

now, you have y by itself since 7-7 = 0

y = 12-7, or y = 5

also its important to note that when the equation is like 2) and uses subtraction (x-4) instead of addition (y +7)-- then you add to both sides

so for 2)-- you'd add 4 to both sides for 4 to cancel out to equal 0

your goal is always to isolate the variable on one side
