Answer: 49.85%

Explanation:

From the information given,

mean = 37

standard deviation = 10

The 68-95-99.7 rule states that 68% of the data fall within 1 standard deviation of the mean. 95% of the data fall within 2 standard deviations of the mean and 99.7% of the data fall within 3 standard deviations of the mean. Thus,

1 standard deviation to the left of the mean = 37 - 10 = 27

1 standard deviation to the right of the mean = 37 + 10 = 47

3 standard deviation to the left of the mean = 37 - 3(10) = 37 - 30 = 7

3 standard deviations to the right of the mean = 37 + 3(10) = 37 + 30 = 67

We can see that the percentage of lightbulb replacement requests numbering between 37 and 67 falls within 3 standard deviations to the right of the mean. This is just half of the area covered by 99.7%. Thus

The percentage of lightbulb replacement requests numbering between 37 and 67

= 99.7/2 = 49.85%

An algebraic expression we can use to compare the price of IBM shares as being $74.50 more than AT&T shares is x + 74.50, where x is the value of AT&T shares.

An algebraic expression consists of variables, terms, constants, and mathematical operations, including addition, subtraction, multiplication, division, and others.

The five algebraic expressions include monomial, polynomial, binomial, trinomial, multinomial.

We can also describe algebraic expressions as falling under the following categories:

An example of an algebraic expression is 2x + 3y.

Let the value of AT&T share = x

Let the value of IBM share = x + 74.50

Thus, we can, algebraically, conclude that AT&T's share price is x while the price of IBM's share is x + 74.50 on that particular day.

Step-by-step explanation:

[tex]\frac{7}{9}[/tex] = [tex]\frac{b}{b - 10}[/tex]  multiply both sides by 9(b -10)

[tex]\frac{9(b - 10)}{1}[/tex]  [tex](\frac{7}{9})[/tex] = [tex]\frac{9(b -10)}{1}[/tex] [tex](\frac{b}{b-10})[/tex]  On the right side of the equation, the 9's cancel out and on the right side of the equation the (b -10) cancels out to leave

7(b -10) = 9b  Distribute the 7

7b - 70 = 9b  Subtract 7b from both sides

-70 = 2b  Divide both sides by 2

Answer:

1.23 x 10 to the 5th power is 123,000.

Step-by-step explanation:

math.

The Equation is 10 + x= 30 and 20 actors are from third grade.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

There are 30 actors in a school play.

There are 10 actors from second grade.

The rest are from third grade.

let the actors in third grade is x.

Equation is:

Actors from second grade + Actors from third grade = Total actors

10 + x= 30

Now, solving

Subtract 10 from both side

10 +x - 10 = 30 - 10

x = 20

as -4 is a negative number and it comes on the left of 0 on a number line

and we know number increase from left to right

so option D is the answer.

• Given the description "Six increased by twice a number is no more than 20", you need to know the following:

- In this case, the word "increased" indicates an Addition.

- The word "twice" indicates a Multiplication by 2.

- "No more than" indicates that six increased by twice a number must be less than or equal to 20.

- The inequality symbol whose meaning is "Less than or equal to" is:

Knowing the information shown before, you can write the following expression to represent "Six increased by twice a number" (Let be "x" the unknown number):

Therefore, you can write the following inequality that models the description given in the exercise:

• Now you need to solve it:

1. Apply the Subtraction Property of Inequality by subtracting 6 from both sides of the inequality:

2. Apply the Division Property of Inequality by dividing both sides of the inequality by 2:

• In order to graph the solution on a Number Line, you can follow these steps:

- Since the inequality symbol indicates that "x" is less than 7, it indicates that 7 is included in the solution. Therefore, you must draw a closed circle over that value.

- Draw a line from the circle to the left.

Then, you get:

The required Z-score with a value of 120 would be 1.33.

A Z-score is defined as the fractional representation of data point to the mean using standard deviations.

The given graph depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15.

As per the given information, the solution would be as

ц = 100

σ = 15

X = 120 (consider the value)

⇒ z-score = (X - ц )/σ₁

Substitute the values,

⇒ z-score = (120 - 100)/15

⇒ z-score = (20)/15

⇒ z-score = 1.33

Thus, the required Z-score with a value of 120 would be 1.33.

Answer:

P(x) = 1.3x² + 0.1x + 2.8

Explanation:

We need to find an equation that satisfies the relationship shown in the table. So, let's replace x by 2 and then compare whether the value of p(x) is 8.2 or not

P(x) = 1.3x³ + 0.1x² + 2.8x

P(2) = 1.3(2)³ + 0.1(2)² + 2.8(2)

P(2) = 16.4

Since P(2) is 16.4 instead of 8.2, this is not a correct option

P(x) = 1.3x² + 0.2x - 2.8

P(2) = 1.3(2)² + 0.2(2) - 2.8

P(2) = 2.8

Since 2.8 and 8.2 are distinct, this is not the correct option

P(x) = 2.3x² + 0.2x + 1.8

P(x) = 2.3(2)² + 0.2(2) + 1.8

P(x) = 11.4

Since 11.4 and 8.2 are distinct, this is not the correct option

P(x) = 1.3x² + 0.1x + 2.8

P(2) = 1.3(2)² + 0.1(2) + 2.8

P(2) = 8.2

Therefore, this is the polynomial function for the data in the table.

So, the answer is P(x) = 1.3x² + 0.1x + 2.8

Given:

Radius, r = 6

Let's find the chance of hitting the shaded area by finding the ratio.

Since the radius of the cirlce is 6, the length of one side of the square is the diameter:

s = 6 x 2 = 12

To find the ratio divide the area of the circle by area of the square. The area of the circle is the shaded area while the area of the square is the total possible area.

Thus,we have:

Therefore, the chance of hitting the shaded region is 78.54%

ANSWER:

78.54%

The formula to find the area of a rectangle is:

Since the rectangle area is 170cm², we can write the following equation.

On the other hand, we know that the width of the rectangle is 6 less than twice its length. Then, we can write another equation.

Now, we solve the found system of equations.

For this, we can use the substitution method.

Step 1: we replace the value of w from Equation 2 into Equation 1. Then, we solve for l.

We can use the quadratic formula to solve the above equation.

Then, we have:

There are two solutions for l.

Since the value of l can not be negative, the value of l is 10.84.

Step 2: We replace the value of l into any of the equations of the system to find the value of w. For example, in Equation 1.

Now, the long side, the wide side and the diagonal of the rectangle form a right triangle.

Then, we can use the Pythagorean theorem formula to find the length of the diagonal.

In this case, we have:

Therefore, the length of the diagonal of the given rectangle is 19.06 cm rounded to 2 decimal places.
