Answer:

x < 12

Step-by-step explanation:

Combine multiplied terms into a single fraction

1/2x < 6

1x/2 < 6

x/2 < 6

2 times x/2 < 2 times 6 is 12 you your answer is x < 12

The probability that the person uses exactly one of the facilities is 0.8.

Given that, there are 120 people in a sport center.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Now, the person uses exactly one of the facilities

= 78+46+41-(21+16+24+9)

= 165-70

= 95

So, probability =95/120

= 0.8

Therefore, the probability that the person uses exactly one of the facilities is 0.8.

C ≤ 4,  J ≤ 1 and 4C + 0.25C ≤ 12

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given, The radio station plays at most 12 hours of music per day.

Let C denotes classical music, J denotes jazz music,

It takes 3.51 months for  Belvedere to weigh the same as Thor

What is a linear equation?

At first it is important to know about equation

Equation shows the equality between two algebraic expressions by connecting the two algerbraic expressions by an equal to sign.

A one degree equation is known as linear equation.

A linear equation needs to be solved here

Let the number of months for Belvedere to weigh the same as Thor be x months

Thor weighs 192 pounds and plans on losing 2.1 pounds each month.

Weight of Thor after x months = 192 - 2.1x

Belvedere weighs 211 pounds and plans on losing 7.5 pounds per month.

Weight of Belvedere after x months = 211 - 7,5x

By the problem,

The linear equation is

192 - 2.1x = 211 - 7.5x

7.5x - 2.1x = 211 - 192

3.51 5.4x = 19

The solution of the given linear equation can be obtained as x = 0.4.

The distributive property states that the product of a number and the sum of other numbers is equal to the sum of their individual products.

It can be expressed as a(b + c + d) = ab + ac + ad.

The given linear equation can be solved as follows,

-2.5(4x - 4) = -6

Use distribute property in the RHS to obtain,

-2.5 × 4x - 2.5 × -4 = 6

=> -10x + 10 = 6

=> -10x = -4

=> x = 0.4

Step-by-step explanation:

the simplest form of the given expression -9a-15-16a+9  is -25a - 6.

What is polynomials?

Using variables and coefficients, polynomials are algebraic expressions. The term "indeterminates" is sometimes used to describe variables. The terms Poly and Nominal, which together signify "many" and "terms," make up the word polynomial. When exponents, constants, and variables are combined using mathematical operations like addition, subtraction, multiplication, and division, the result is a polynomial (No division operation by a variable). The expression is categorized as a monomial, binomial, or trinomial based on the number of terms it contains.

-9a-15-16a+9

So here "a" is a variable

we have -a(9+16)+9-15

= -25a - 6

Hence the simplest form of the given expression is -25a - 6.

TRUE extrapolation is the use of the regression line to estimate a mean of y-values for an x-value that is far outside the x-range of data.

"Information available from the question"

In the question:

Extrapolation is the use of the regression line to estimate a mean of y-values for an x-value that is far outside the x-range of data.

Answer in True or False.

Now, According to the question:

Let's Know:

What is extrapolation?

A statistical technique called extrapolation aims to understand the unknown data from the known data. It uses historical data to attempt to predict future data. For instance, using the current population size and growth rate to project the size of a population in a few years.

Predicting hypothetical values outside of a specific data set is the goal of extrapolation.

Contrary to interpolation, which typically focuses on estimating past values, extrapolation is used to predict unknown future values due to its predictive nature.

Hence, TRUE extrapolation is the use of the regression line to estimate a mean of y-values for an x-value that is far outside the x-range of data.

According to the statement, the lengths of the line segments PR and QR are known and the length of line segment PQ can be known by Euclidean geometry and algebra:

PR = PQ + QR

PQ = PR - QR

If we know that PR = 10 and QR = 8, then the line segment PQ is calculated below:

Part A) If the original price of the model car was $40, and it was sold on the third day, with a daily discount of 5%, the sales amount is $34.30.

Part B) The percentage discount from the original price is 14%.

The percentage discount is the total discount divided by the original price multiplied by 100.

In this instance, we compute the total discount as $5.70, then express this value as a numerator with $40 as the denominator.  The quotient is multiplied by 100.

Original price of the model car = $40

Daily discount = 5%

The date the car sells = the third day

The sales price on the third day = $34.30 ($40 x 95% x 95% x 95%)

Total discounts = $5.70 ($40 - $34.30)

Percentage discount for three days =14.25% ($5.70/$40 x 100)
