which of the follow r-values represents the no or low coorelation
Answers
The r-value that represents the no or low correlation is 0.0
How to determine the r-value?For a r value to show no correlation, then the r value must be 0 or close to 0
Since the r values are not given, then we can assume that the r value is 0
Hence, the r-value that represents the no or low correlation is 0.0

A fabric store is having a sale. The price of every item in the store has been reduced by 30%. Which equation shows the
proportional relationship between the regular price, r, of an item and its sale price, s?
Answers
Equation to show the proportional relationship between the regular price, r, of an item and its sale price, s is 10s -7r=0.
What is sale price?A sale price is the discounted price at which goods or services are being sold. This price is usually offered for a limited period of time, typically to spur sales during a slow period or to sell off excess inventory.
Let the regular price be r and sale price be 's'
Since price of every item reduced by 30%.
So, sale price will be
[tex]s= r- 30% of r[/tex]% of r
[tex]s= r- \frac{30}{100} *r[/tex]
s= r - 0.3 r
s= 0.7 r
s-0.7r=0
or, 10s -7r=0
Thus, equation shows the proportional relationship between the regular price, r, of an item and its sale price, s :10s -7r=0

Answers
Answer:
Two
Step-by-step explanation:
3,5 or 7 out of possible 12 spins
3 / 12 of the time she will win
$ 4 is 8 spins
8 spins * 3/12 = 2 wins
ANSWER
2 prizes
Step-by-step explanation:
$4 ÷ $0.5 = 8
Total points on spinner = (1,2,3,4,5,6,7,8,9,10,11,12)
Required for winning = (3, 5, 7)
5+7 = 12
3/12
P(win) = 3/12 simplified is 1/4
(1/4) × (8) = 2

Elena should go to the south market because there is 0.52 probability of both cherries and asparagus being available.
How to determine the market to choose?The table is given as:
North market South market
Cherries 0.96 0.8

The probability of buying both produce at both markets is calculated as:
P(North) = 0.96 * 0.5 = 0.48

They give you the meter per year so you look at the values and move the decimal and see if it can round to the whole number 9.
Looking at the four next to nine can't round so 9,460,000,000,000 becomes 9 * 10^15 m per year.

14x15-10x10=110
A=110
Step-by-step explanation:
Answer:
First, we'll need to find the length of each side.
10m + 4m = 14m
10m + 5m = 15m
Now that we know the length of 2 sides, let's call them the "North" and "West". The measure or length of "South" is the same as "North" and the measure or length of "East" is the same as "West".
To find the Area of the WHOLE square, we'll need to multiply both lengths.
14 × 15 = 210m^2
To find the area of the given figure:
1. Find the Area of the 10m of the "North" and the 10m of the "West".
10 × 10 = 100m^2
2. Minus the Area of the product of 10m of the "North" and the 10m of the "West" from the Area of the WHOLE square.
210m^2 - 100m^2 = 110m^2
The area of the given figure is 110m^2.

Both of the triangles are similar but they look like they have been rotated a bit. Sides x is similar to 12 and side 5 (the hypotenuse) is similar to 13. Therefore we can just set up an equation and cross-multiply.
[tex]\frac{x}{5} = \frac{12}{13}[/tex]
[tex](x * 13) = (5 * 12)[/tex]

(a) sin⁻¹(√35/14)
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relations between sides and angles in a right triangle. Here, the given sides AB and AC are the side opposite angle C, and the hypotenuse (opposite right angle B). That means the relevant relation is ...
Sin = Opposite/Hypotenuse
sin(C) = AB/AC
__
For this problem, substituting values gives ...
sin(C) = (3√5)/(6√7) = (1/2)√(5/7) = (1/2)(√35)/7 = (√35)/14
C = arcsin((√35)/14)
_____
Additional comment
Choice B can be eliminated on the grounds that the fraction is not reduced to lowest terms. Choices C and D are eliminated because they assume a cosine relation is involved. That is, you can choose the correct answer based on SOH CAH TOA without concerning yourself with the details of the radical expression.

Answers
Answer:
about 21 students
Step-by-step explanation:
total students: 150 students enrolled
recognize all letters: 6/7 of the students
To find 1/7 of the students: divided the 150 by 7
150/7 = 21.4285 this is for 1/7th of students
since 1/7th of the students need to learn the alphabet (7/7 - 1/7 = 6/7)
OR
150/7 = 21.4285 this is for 1/7th of students
150/7 x 6 = 128.57 this is for 6/7th of students
150 - 128.57 = 21.4285
