The distribution of the z-scores for the time it takes to solve a crossword puzzle that is strongly skewed to the right with a mean of 30 minutes and a standard deviation of 15 minutes can be calculated using the formula z=(x-mean)/standard deviation. Z-scores can be used to determine how far a data point is from the mean in terms of standard deviations.

The distribution of the time it takes for different people to solve a certain crossword puzzle is strongly skewed to the right, with a mean of 30 minutes and a standard deviation of 15 minutes. The distribution of z-scores for those times can be calculated using the formula:

z = (x - mean)/standard deviation

For example, if a person takes 45 minutes to solve the puzzle, the z-score would be:

z = (45 - 30)/15 = 1

This means that the person's time is one standard deviation above the mean.

Final answer:

To represent the relationship between Matt and Andy's ages mathematically, let x be Andy's age, and express Matt's age as 2x + 5. The inequality x + (2x + 5) < 35 simplifies to x < 10, indicating Andy's age must be less than 10.

Explanation:

The question involves creating an inequality to represent the relationship between Matt and Andy's ages, where Matt is five years older than twice Andy's age, and the sum of their ages is less than 35.

Let x represent Andy's age. The formula for Matt's age would be 2x + 5. To find the range of possible values for Andy's age, you would write the inequality  x + (2x + 5) < 35.

Solving this inequality involves combining like terms and isolating the variable x.

Step 1: Combine like terms.

x + 2x + 5 < 35

Step 2: Simplify the inequality.

3x + 5 < 35

Step 3: Subtract 5 from both sides to isolate the term with x.

3x < 30

Step 4: Divide both sides by 3 to solve for x.

x < 10

This tells us that Andy's age must be less than 10 for the conditions to be met.

3x-6 = 2x+11

3x = 2x+17

x = 17

3(17)-6 = 45

2(17)+11 = 45

45+45 = 90

answer is C 90 degrees:right

Step-by-step explanation:

1 yard = 3 ft

10/3 = 3 1/3 yards

3 1/3 x 4 = 13 1/3 square yards

multiply 12 x 0.75

12 x 0.75 = 9

answer is B. 9 pounds

Answer:

Josh will need 9 pounds Option B.

Step-by-step explanation:

Josh wants to make a set of 12 ceramic cups.

For each cup he will need 0.75 pound of clay

We have to calculate how many pounds of clay does Josh need for 12 ceramic cups. So we have to multiply 12 cups by 0.75.

for 12 cups he will need = 12 × 0.75 = 9 pounds.

Josh will need 9 pounds to make a set of 12 ceramic cups.

Answer:

Your answer would be A 10cm

Two complementary angles are given as 4x - 16 and 2x + 10. Solving for x we find x = 16. Substituting x into the expressions for the angles, we find the angles to be 48 and 42 degrees.

The task here is to find the value of two angles that are complementary. Given the expressions for the angles are 4x - 16 and 2x + 10. As complementary angles, they sum up to 90 degrees. Hence, mathematically, we can express this as (4x - 16) + (2x + 10) = 90.

Solving the equation, combine like terms to get 6x - 6 = 90. Then, add 6 to both sides to get 6x = 96. Divide each side by 6 to find x, hence x = 16.

Substitute x = 16 into 4x - 16, therefore the first angle is 4×16 - 16 = 48 degrees. Similarly, substitute x = 16 into 2x + 10, hence the second angle is 2×16 + 10 = 42 degrees. The angles are thus 48 and 42 degrees, which adds up to 90).

To put the given equation of a sphere in standard form, complete the square for x, y, and z, and combine constant terms on the right side. The standard form of the sphere's equation is (x + 2)2 + (y - 3)2 + (z - 3)2 = 28, with a center at (-2, 3, 3) and a radius of √28.

To write the equation of the sphere in standard form, we will complete the square for the x, y, and z terms in the given equation x2 + y2 + z2 + 4x − 6y − 6z = −6.

First, we organize the variables and separate the constants:

x2 + 4x + y2 - 6y + z2 - 6z = -6

We then complete the square for each variable by adding and subtracting the square of half the coefficient of the linear term:

x2 + 4x + 4 - 4 + y2 - 6y + 9 - 9 + z2 - 6z + 9 - 9 = -6

Now we can rewrite this as:

(x + 2)2 - 4 + (y - 3)2 - 9 + (z - 3)2 - 9 = -6

Combining the constant terms on the right side we get:

(x + 2)2 + (y - 3)2 + (z - 3)2 = 4 + 9 + 9 + 6

Which simplifies to:

(x + 2)2 + (y - 3)2 + (z - 3)2 = 28

The sphere's center is located at (-2, 3, 3) and has a radius of √28. In standard form, the equation of the sphere is:

(x + 2)2 + (y - 3)2 + (z - 3)2 = 28

Answer:  The required value of c that makes the given statement true is 5.

Step-by-step explanation:  We are given to find the value of c that makes the following statement TRUE :

[tex]-2x^3(cx^3+x^2)=-10x^6-2x^5~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

To find the value of c, we need to equate the coefficients of the same powers of the unknown variable x.

From equation (i), we have

[tex]-2x^3(cx^3+x^2)=-10x^6-2x^5\\\\\Rightarrow -2cx^{3+3}-2x^{3+2}=-10x^6-2x^5\\\\\Rightarrow -2cx^6-2x^5=-10x^6-2x^5.[/tex]

Equating the coefficients of [tex]x^6[/tex] on both sides of the above equation, we get

[tex]-2c=-10\\\\\Rightarrow c=\dfrac{-10}{-2}\\\\\Rightarrow c=5.[/tex]

Thus, the required value of c that makes the given statement true is 5.

The simplified form of the expression (y^8)(y^2) is y^10, found by applying the laws of exponents that dictate adding the exponents when multiplying with the same base.

The simplified form of the expression (y8)(y2) can be found using the laws of exponents which state that when multiplying two powers with the same base, you add the exponents. Here, since the base is y, and we have exponents 8 and 2, we add them together:

y8 × y2 = y8+2

This simplifies to y10, which is the compressed form of the given expression.
