The correlation that exists between the temperature and the number of fruits sold is positive but is almost negligible.

The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.

A result of zero indicates no relationship at all, therefore, independent variable.

We know that the correlation coefficient is given by the formula,

[tex]r =\dfrac{\sum\left(x_{i}-\bar{x}\right)\left(y_{i}-\bar{y}\right)}{\sqrt{\sum\left(x_{i}-\bar{x}\right)^{2} \sum\left(y_{i}-\bar{y}\right)^{2}}}[/tex]

r = correlation coefficient

[tex]x_{i}[/tex] = values of the x-variable in a sample

[tex]\bar{x}[/tex] = mean of the values of the x-variable

[tex]y_{i}[/tex] = values of the y-variable in a sample

[tex]\bar{y}[/tex] = mean of the values of the y-variable

Calculate the value of [tex](x_i-\bar{x})(y_i-\bar{y}),\ (x_i-\bar{x})^2,{ \rm and}\ (y_i-\bar{y})^2[/tex] each separately, and then find the sum of them as shown below, therefore, the formula can be written as,

[tex]r =\dfrac{571.5}{261.5\times 1566.833333}= 0.0014[/tex]

Hence, the correlation that exists between the temperature and the number of fruits sold is positive but is almost negligible.

Step-by-step explanation:

Answer:

y = -2(x + 1)^2 + 8

Step-by-step explanation:

The equation of a parabola can be written in the form;

y = a(x-h)^2 + k

where a is the multiplier (h,k) is the vertex

so h = -1 and k = 8

Plug in these values

y = a(x + 1)^2 + 8

So to get the value of a, we use the point where the parabola passes through which is the point (1,0)

Simply substitute the values of x and y

0 = a(1 + 1)^2 + 8

0 = a(2)^2 + 8

-8 = 4a

a = -8/4

a = -2

So therefore the equation of the parabola is ;

y = -2(x + 1)^2 + 8

The required equation of parabola with given vertex and point of passing is [tex]y=-2(x+1)^{2}+8[/tex].

Given data:

The vertex of parabola is, (-1, 8).

The vertex is passing through (1, 0).

We know that standard equation parabola is,

[tex]y=a(x-h)^{2}+k[/tex]

Here, a is any multiplier, h and k are the vertices.

From the given problem,

h = -1

k = 8

So substituting the values as,

[tex]y=a(x-(-1))^{2}+8\\y=a(x+1)^{2}+8[/tex]..............................................(1)

To obtain the value of a, we use the point where the parabola passes through which is the point (1,0). Here, x = 1 and y =0.

So,

[tex]0=a(1+1)^{2}+8\\\\a = -2[/tex]

Substitute the value of a in equation (1) as,

[tex]y=(-2)(x+1)^{2}+8\\\\y=-2(x+1)^{2}+8[/tex]

Thus, the required equation of parabola is  [tex]y=-2(x+1)^{2}+8[/tex].

Step-by-step explanation:

x=32 degrees

Step-by-step explanation:

Angles in equilateral triangles are equal, each angle is 60 degrees

2x-4 =60

+4

2x = 64

÷2

x = 32

Also, y will be 12 (12x5=60)

Hope this helps!

let the other angle be x degree

bigger angle = x +36°

According to the question,

x+36° + x° = 180°

=> 2x = 180–36

=> x = 144/2

=> x = 72°

Measure of the bigger angle = x + 36

= 72° + 36°

= 108°

for the 1st one, m=10 and b=2 because from the word problem it says it starts at 10 which would be 10 on the y axis being where the line would pass through and spending 2 a week would be the slope because he is losing 2 per week its a negative slope so y=10x-2.

for the second one m=48 and b=44 its just like the last one but with different numbers but comment if you want me to explain it but the answer is y=48x-44.

Answer:

-2

Step-by-step explanation:

The value of c is -4, therefore the additive inverse should be added to get the answer 0

The roots of the quadratic equation x² – 2x + c = 0 are a and –b. Then the value of c is a² – 2a.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

For which values of c does the quadratic equation

x² – 2x + c = 0 ...1

Two roots of opposite signs

Let the two roots of the opposite signs be a and –b

x = a, –b

Then we have factorized the equation,

(x + b)(x – a) = 0

On solving, we have

x² + (b – a)x – ab = 0 ...2

In comparing equation 2 with equation 1, we have

⇒  b – a = –2

⇒ b = –2 + a

and

⇒ c = a(a – 2) = a² – 2a

Option b - $163.07

Step-by-step explanation:

Given :  A loan of $7,500 with an 11% interest rate compounded monthly over a period of 5 years.

To find : Monthly payment

Solution : Formula to find monthly payment

Monthly Payment = Amount / Discount factor

Discount factor

where ,

Amount = $7500

Rate= 11%=0.11

Time = 5 years

Now, put i and n in Discount factor ,

Monthly payment,

Therefore, Option b is correct monthly payment = $163.07

Answer:

The answer is $163.07

Step-by-step explanation:

To find the monthly payment:

[tex]i = \frac{0.11}{12} = 0.0091[/tex]

Time = 5 years

5 x 12 = 60

Discount factor

[tex]D = \frac{1-(1 + i) -^{n}}i[/tex]

[tex]D = \frac{1 - (1+ 0.009)-^{60} }{0.009} \\[/tex]

[tex]D = \frac{0.421}{0.009} = 46.77[/tex]

Monthly payment

Answer:

The last one

Step-by-step explanation:

K so first look at y intercept which is +5, so we eliminate A and C, then the graph opens up so the b in ax+bx+c has to be positive which is D

the point ( 0 ; 5 ) in on the curve

so f(0) = 5

choice between :

x² - 2x + 5 or x² + 2x + 5 then :

we have the point (1 ; 4)

with x² - 2x + 5

f(1) = 1² - 2*1 + 5 = 1 - 2 + 5 = 4

so it's correct

=> x² - 2x + 5 is the right one

The mean measurement is the average value of the leaves

The possible measurement of the 6th leaf is 13.3

The dataset is given as:

14.2, 13.8, 12.6, 13.4 and 11.5

Sort the data elements

11.5, 12.6, 13.4, 13.8 and 14.2

Calculate the mean

[tex]\bar x = \frac{11.5 + 12.6 + 13.4 + 13.8 + 14.2}{5}[/tex]

[tex]\bar x = \frac{65.5}{5}[/tex]

[tex]\bar x = 13.1[/tex]

So the mean is 13.1 and the median is 13.4

For the mean to increase, the 6th dataset must be greater than 13.1.

For the median to decrease, the 6th dataset must be less than 13.4
