Answer:
Step-by-step explanation:
-0.71
The r - value -0.71 represents the strongest correlation which is negative correlation.
What is the correlation coefficient?The correlation coefficient is a quantitative method of calculating correlation. It is a statistical concept, which helps in establishing a relation between predicted and actual values obtained in a statistical experiment.
For the given situation,
The options has the r - values, we need to check which option represents the strong correlation.
Now., The relationship between two variables is generally considered strong when their r value is larger than 0.7.
A correlation of r = -0.71 suggests a strong, negative association between two variables.
A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.
Hence, we can conclude that the r - value option (D) -0.71 represents the strongest correlation which is negative correlation.

Help please problem is worded weird
Answer:100
Step-by-step explanation:
Expand
x = 150 - 0.5x
Add 0.5x to both sides
x + 0.5x = 150
Simplify x + 0.5x to 1.5x
1.5x = 150
Divide both sides by 1.5
x = 150/1.5
Simplify 150/1.5 to 100
x = 100
Answer: the correct awnser is 100

Ava turtle is half as old as her parrot in 10 years her turtle will be 3/4 as old as her parrot .write the equation to represent this situation.How old is avas turtle
Answer:
13
Step-by-step explanation:
I think the turtle would be 13 and 1/3 because we know that the turtle is half as old as the parrot. So if we divide 10 by 3/4 we can get how old the turtle is now
The system of the equation is :
[tex]2x=y\\3y-4x=10[/tex]
Thus, the age of the ava's turtle is 5 years.
Given:
Ava's turtle is half as old as her parrot.
The turtle will be 3/4 as old as her parrot in 10 years.
Let us assume the age of the turtle is x years and the age of the parrot is y years.
According to the first statement, the variables can be related as:
[tex]{x}=\dfrac{y}{2}\\2x=y[/tex]
According to the second statement, the variables can be related as:
[tex]\begin{aligned}x+10&=\dfrac{3}{4}(y+10)\\4(x+10)&=3(y+10)\\4x+40&=3y+30\\4x-3y&=-10\\3y-4x&=10\end{aligned}[/tex]
Thus, the system of the equation is :
[tex]2x=y\\3y-4x=10[/tex]
By solving the above system of the equation, we get x=5 and y=10.
Thus, the age of the ava's turtle is 5 years.

Solve for the indicated variable x/9 - g = a for x
Answer:
x = 9(a+g)
Step-by-step explanation:
x/9 - g = a
Add g to each side
x/9 - g+g = a+g
x/9 = a+g
Multiply each side by 9
x/9 * 9 = 9(a+g)
x = 9(a+g)

Michael invests USD 20 000 at 9.6% p.a. compounded monthly.
How long will it take for his investment to reach USD 25 000?
Given :
A = 25000
P = 20000
r % = 9.6 % = 0.096
n = 12
To Find :
The time taken say t.
Solution :
We know, compound interest is given by :
[tex]A=P(1+\dfrac{r}{n})^{n.t}[/tex]
Taking log both sides :
[tex]A=P(1+\dfrac{r}{n})^{n.t}\\\\log\ \dfrac{A}{P}= n.t\times log( 1+\dfrac{r}{n})\\\\t =\dfrac{1}{n}\times \dfrac{log\ \dfrac{A}{P}}{log(1+\dfrac{r}{n})}\\\\\\t=\dfrac{1}{12}\times \dfrac{log\ \dfrac{25000}{20000}}{log(1+\dfrac{0.096}{12})}\\\\\\t=2.33\ years[/tex]
Hence, this is the required solution.

Hope It Helps!Michael is saving to buy a car. He has 1/4 what he needs to buy the car. His savings account has a balance of $1000. How much more does he need to save?
Answer:
3000
Step-by-step explanation:
If you take the amount he already has (1000) and multiply by the reciprocal (4) you'll get $4000, the amount that the car costs. From there subtract the amount he already has (1000) and you get the amount he still needs (3000).
1/2 = q + 2/3
and
p - 3 1/6 = -18.73
please help, im giving 20 points
Answer:
see below
Step-by-step explanation:
1/2 = q + 2/3
Subtract 2/3 from each side
1/2 -2/3 = q+2/3-2/3
Getting a common denominator of 6
3/6 - 4/6 = q
-1/6 =q
p - 3 1/6 = -18.73
Add 3 1/6 to each side
p - 3 1/6 + 3 1/6 = -18.73 + 3 1/6
p = -18 73/100 + 19/6
Get a common denominator
p =- 5619/300 + 950/300
= -4669/300
=-15 169/300
