Using a calculator, it is found that the correlation coefficient for this data is given by:

B. -0.901.

What is a correlation coefficient?

It is an index that measures correlation between two variables, assuming values between -1 and 1.If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.

To find the coefficient, which has symbol r², we input in a calculator the values of x and the values of y, hence:

r² = -0.901.

Which means that option B is correct.

Please Help !!! its a math problem What is the range of the quadratic equation whose graph contains the following points?

Vertex at (0, 4)
Other points on graph are (-2, 0), (-1, 3), (1, 3) and (2, 0).

Answers

Range of a Quadratic Function

The range tells us the possible y-values that occur in the function.

When describing the range, we can write an inequality using y.

Examples: y > 6, y ≤ 10

When describing the range of a quadratic function, we typically use the ≥ or ≤ symbols when writing the inequality.

To write the range of a quadratic function,

Find the vertexDetermine whether the parabola opens up or downSet y ≥ or ≤ the y-coordinate of the vertex

Solving the Question

We're given:

Vertex at (0,4)Other points on the graph: (-2,0), (-1,3), (1,3), (2,0)

Because we're directly given the vertex, we just have to determine now whether the parabola opens up or down.

If the other points on the graph always have a lower y-coordinate value, then the graph opens downIf the other points on the graph always have a greater y-coordinate value, then the graph opens up

The other points that fall on the graph that we're given all have a lower y-coordinate value than 4, that means this parabola opens down.

Therefore, all other y-values for the function will be less than 4.

Therefore, y ≤ 4.

Answer

y ≤ 4

Three coins are tossed. Find the probability that 2 land on heads

Answers

The probability of getting two coins landing on heads is 3/8 or 0.375

Answer:

1/8

Step-by-step explanation:

Probability denotes the possibility of something happening. It is a field of mathematics that studies the probability of a random event occurring. From 0 to 1.

the value is expressed.

When a coin is tossed, the chance of it landing on heads is 1/2, and vice versa.

So, we divide 1/2 by the number of times it lands on heads to get 1/4. However, when the second one landed on tails, we must multiply it by 1/2 again, making 1/4 x 1/2 = 1/8.

88+36 is the same as ? + 34

Answers

Answer:

The answer would be 90.

Step-by-step explanation:

There are two ways to solve this problem.
Option 1:  See that 88+36 is equal to 124. Then subtract 34 from 124 to get your answer of 90.
Option 2. See that you subtracted two from 36 to get 34. To balance the equation out, you must add two to 88 to get an answer of 90.
I hope this helps! :)

Hey there!


88 + 36 VS ? + 34

88 + 36 VS x + 34

88 + 36 = x + 34

124 = x + 34

NEW EQUATION:

124 = x + 34

x + 34 = 124

SUBTRACT 34 to BOTH SIDES

x + 34 - 34 = 124 - 34

SIMPLIFY IT!
x = 124 - 34

x = 90


Therefore, the mystery number/answer is: 90

The value of π is:

π = 22/7

Evaluate the quotient

π = 3.14285714286

From the question, the digits 1 to 8 have to appear just once.

So, we approximate the number up to the point where any of the given digits has more than one occurrence.

Given that f(x)=x3​, find

Answers

Answer:

(f ∘ f)(–1) = –1

Step-by-step explanation:

To solve a composite function, rewrite using brackets and solve from inside to outside.

(f ∘ f)(x) is the same as:    f[f(x)]

Given that x = –1 in (f ∘ f)(–1), we are solving for:

f[f(–1)] = ?

Solve for f(–1) inside the square brackets first.

f(x) = x³

f(–1) = (–1)³    Simplify.

f(–1) = –1       Solved the inside.

Substitute f(–1) = –1 into the square brackets.

f[f(–1)] = f[–1]

Now, we can solve the outside.

Solve with the equation of the function, x³.

f[–1] = x³

f[–1] = [–1]³     Substitute x = –1.

f[–1] = (–1)³     Simplify.

f[–1] = –1        Final answer

then, 2x+y=5...(1)

x+y=3...(2)

2x+y-x-y=5-3

or, x=2

then y=1

Answer:

c = 2

m= 1

Step-by-step explanation:

Im guessing you will need to use simultaneous equations

Let 'c' be the cost of 1 cookie and 'm' be the cost of 1 muffin

1) 2c + 1m = 5 -

2) 1c + 1m = 3

c / = 2

So c is 2

1) Label the equations 1 and 2

2) Find a common term in both equations ( bold)

3) Eliminate 1m by subtracting equation (2) from equation 1

( To know if to subtract or add always follow this rule: If the common terms and the same sign subtract if they are a different sign add)

4) Substitute c in any of the equation ( 1 or 2) to find m

I will use equation 2 because I think its easier

2) 1c+1m = 3

2 + m = 3

m= 3-2

m= 1
