The correlation is  a weak positive correlation

Answer:

Step-by-step explanation:

In statistics, association is any statistical relationship, whether causal or not, between two random variables or bivariate data.  One is independent and other is dependent variable.   In the broadest sense correlation is any statistical association, though in common usage it most often refers to how close two variables are to having a linear relationship with each other.

Examples are exercise and sickness are negatively correlated.

Study hours and marks are positively correlated

When correlation is nearer -1 or +1 there is a strong correlation.  When correlation is nearer to 0 than to 1 or -1 we say that there is a negative correlation.

Here sign of r is positive.

Hence there is a positive and weak correlation.

Brad has 10 lb of oranges to make 12 bowls of fruit salad. His recipe requires 12 oz of oranges for each bowl. Does Brad have en
Illusion [34]

Answer: Yes, Brad has enough oranges.

Step-by-step explanation:

Given :

The orange required for one bowl = 12 oz

Thus orange required for 12 bowls = \frac{12}{1}\times 12=144oz

Oranges available with Brad for 12 bowls = 10 lb = 10\times 16=160oz

(1lb=16oz)

As organges required is less than oranges available with Brad, thus Brad has enough oranges.

Vita has a pice of rope that is 5 meters long. She cuts the rope into pieces that are each 1/3 meter long. How many pieces does
sp2606 [1]
Normally you would divide something like this by the cuts made. So if there were cuts of 2 inches on a 10 inch rope, then you should divide 10 by 2. It's the same with this:
5/ \frac{1}{3} = 5*3, 15 \ pieces
Multiply by the reciprocal when you are dividing fractions.

What are the values of x and y?
tresset_1 [31]

Step-by-step explanation:

y is easy.

it is the Hypotenuse (baseline) of the small right-angled triangle created by the height (8) of the main triangle, the segment 6 of the main Hypotenuse and y.

so, Pythagoras :

y² = 8² + 6² = 64 + 36 = 100

y = 10

x is a bit more complex.

I think the easiest way to get it is to know that the height of a right-angled triangle to the Hypotenuse is the square root of the product of both segments of the Hypotenuse.

so, if we call the segments of the Hypotenuse a and b with a = 6, we have

x = a + b = 6 + b

height (8) = sqrt(a×b) = sqrt(6b)

therefore,

6b = height² = 8² = 64

b = 64/6 = 32/3 = 10 2/3 = 10.66666666...

so,

x = 6 + 10.66666... = 16.666666666...

round it to what is needed. e.g. 2 positions after the decimal point (hundredths) ? then it would be 10.67
