Color would be the same for both statue and stone buildings.

Let's, consider paint black as = x

and paint white as = y

If both the paints are mixed then paint z which is grey is formed.

Represented as,

x(black) + y(white) = z(grey)

Whereas, for the stone building double the amount of black and white colors are being used,

2x + 2y = 2z, coating of grey color would be also double.

Canceling 2 from both sides,

x + y = z

x(black) + y(white) = z(grey)

Therefore color would be the same for both statue and stone buildings.

Given,

Sample mean = ±3 of true mean

Standard error = 1.8

Therefore,

Required probability of sample mean being within 3 units of the true mean is,

P ( sample mean - 3 < mean < sample mean + 3 )

= P [( sample mean - 3 ) - mean / 1.8 ] < mean - sample mean / 1.8 < [ ( sample mean + 3 ) - mean / 1.8 ]

= P ( - 1.67 < ∉ < 1.67)

= P (∉ < 1.67) - P( ∉ < 1.67)

= 0.952 - 0.047

= 0.905

Hence, the probability that the sample mean is within 3 units of the true mean if the standard error is 1.8 is 0.905.

8 units is the radius of the circle with a circumference of 16π.

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The circumference of a circle is expressed mathematically as;

C = 2 × π × r

Where r is radius and π is constant pi ( π = 3.14 )

Given the data in the question;

To find the radius of the circle, plug the given value into the circumference formula and solve for r.

C = 2 × π × r

16π = 2π × r

r = 16π / 2π

r = 16/2

Radius r = 8

Therefore, the radius of the circle is 8.

If you change the 2H₂ to 3H₂ molecules and balance the equation the equation will produce three molecules of water.

The provided chemical equation is,

2H₂ + O₂ → 2H₂O.

Changing 2H₂ with 3H₂

The chemical equation becomes,

3H₂ + O₂ → 2H₂O.

By doing this, the equation has become completely imbalanced,

So first we will balance it,

3H₂ +3/2O₂ → 3H₂O

Now, there will be 3 molecules of water formed.

As we observe the reaction more closely, we can see that the number of atoms of all the elements are equal on both the sides of the reaction.

Answer:

13/102

Step-by-step explanation:

We start with 52 playing cards. Of these 52 cards, 13 are diamonds, So the probability of a diamond is 13/52, or 1/4. There are now 51 cards left. Since the diamond is a red card, there are 26 black cards. So the probability of a black card is 26/51. Multiplying 1/4 and 26/51, and then simplifying, we have 13/102.

Answer:

-5/6

Step-by-step explanation:

The reason why the reciprocal is -5/6 is because to isolate the variable with a fraction attached is to multiply it by swapping the numerator and denominator. Also making sure that if the number is a negative, to multiply the number by another negative to cancel it out.

When we divide 27 by 7, we have 3; 3 * 7 = 21

27 - 21 = 6; we have a remainder of 6

Divide the remainder by 7, we have 6/7

Therefore, we have:

AB is congruent to CD as an angle in front of them is congruent so, the sides are also congruent.

So, all coordinates are shown on the graph as follows:

Answer:

m<A = 50°

Step-by-step explanation:

supplementary angles add up to 180°

m<B = 2x + 30

we don't know m<A, so we'll say the value of it is x

2x + 30 + x = 180°

3x + 30 = 180

3x = 150

x = 50

plug this value back in for x

m<B = 2(50) + 30 = 130

m<B = 130°

m<A = x = 50

m<A = 50°

to prove these are supplementary angles, 130 + 50 = 180

Considering the product and the sum of the roots of the quadratic function, the numeric value of the expressions are given as follows:

1. [tex]\beta x^2 + \alpha x^2 - \alpha\beta = \frac{1}{4}(x^2 - 1)[/tex]

2. [tex]\frac{\alpha}{\beta} + \frac{\beta}{\alpha} = -\frac{7}{4}[/tex]

A quadratic function is defined according to the following rule:

y = ax² + bx + c.

In which a and b are the coefficients of the equation.

Supposing that the equation has roots [tex]\alpha[/tex] and [tex]\beta[/tex], the product and the sum of the roots of the quadratic function are given as follows:

In this problem, the equation is:

4x² - x + 1.

Hence the coefficients are:

a = 4, b = -1, c = 1.

Then the product and the sum of the roots of the quadratic function are given as follows:

Then the numeric values for the expressions can be found as follows:

[tex]\beta x^2 + \alpha x^2 - \alpha\beta = x^2(\alpha + \beta) - \alpha\beta = \frac{1}{4}x^2 - \frac{1}{4} = \frac{1}{4}(x^2 - 1)[/tex]

For the second expression:

[tex]\frac{\alpha}{\beta} + \frac{\beta}{\alpha} = \frac{\alpha^2 + \beta^2}{\alpha\beta} = 4(\alpha^2 + \beta^2)[/tex]

The sum of the squares of the roots is:

[tex]\alpha^2 + \beta^2 = (\alpha + \beta)^2 - 2\alpha\beta[/tex]

Hence:

[tex]\alpha^2 + \beta^2 = \frac{1}{16} - \frac{1}{2} = -\frac{7}{16}[/tex]

Then:

[tex]\frac{\alpha}{\beta} + \frac{\beta}{\alpha} = -\frac{28}{16} = -\frac{7}{4}[/tex]

the constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.

We are given that 1 bulb out of every 9 bulbs is defective.

So, this means that if there is a total of 9 bulbs, then 1 bulb in it will be defective.

Let us assume:

Total bulbs = 9

So, this implies that:

Defective bulbs = 1

Constant of proportionality = Defective bulbs / Total bulbs.

Substituting the values in this, we get that:

Constant of proportionality = 1 / 9

Therefore, we get that, the constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.

Polynomials are closed under the multiplication operation, meaning that the result of the multiplication between two polynomials will always be a polynomial.

To multiply polynomials, we first apply the distributive property, multiplying all terms, then we combine the like terms, that is, adding all the terms that have the same exponents.

Since all the factors of the multiplications will be of polynomial terms,  the results of the multiplication will be polynomial, and so will the like terms combined, hence polynomials are closed under the multiplication operation.

Using greatest common factor (GCF), the greatest possible length of each pipe is 12 dm.

The greatest common factor (GCF) of a set of numbers is defined as the largest common positive integer that divides each number into equal parts with zero remainder.

If a carpenter has 2 pipes which are 60 dm and 72 dm long, respectively and he cuts them into equal lengths, then the greatest possible length of each pipe is the GCF of 60 and 72.

60 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Answer:

- 21

Step-by-step explanation:

They lost 14 yards, then lost and additional 7 more. You would simply add and make it a negative number due to the key word " lost ".

The equation would look like this: -14 + ( -7 ).

Another way to solve this equation is to multiply. ( + ) x ( - ) = -.

Your equation will the look this this: -14 - 7.

Now you just solve.

Thus, your answer should be - 21.

Hopes the helps!

Have a great day.

Answer: -21

Step-by-step explanation:

.A football team will lose an additional 7 yards if they lost 14 on their first play.

. Since the first play resulted in a loss of 14 yards, the integers that reflect the overall change in yards for the two plays are negative.

.In the second play, we score 14 points but lose 7 yards, which is a loss of 7 points.

.Negative 14 + Negative 7 = Negative 21, which is the overall change in yards.

. Hence, the answer would be -21 yards.

. -21 would be the correct integer that will represent the the total change in yards for the two plays.
