a-b ac≥ bc
If az b, then a + c≥ b + c
If c> d, then a-c If a

Answers

Answer 1

The inequalities 3 and 4 are the right ones, because they are actually properties of inequalities.

What do math inequalities mean?

inequality, A declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.Income gap, gender inequality, access to health care, and social class are some of the most prominent instances of social inequality. Some people receive better and more skilled care in the medical field than others.

The inequalities 3 and 4 are the right ones, because they are actually properties of inequalities.

The alternate options are incorrect. For instance, the first option, a - b a + b, is false because the expression would be ruined if you don't apply the same adjustment to both sides of the inequality.

Both options 2 and 5 are incorrect.

The proper responses are thus 3 and 4.

A bag of marbles contains 6 blue glass marbles, 5 yellow glass marbles, 12 blue stone marbles, and 3 yellow stone marbles. What is the probability of selecting a marble and having that marble be either a blue marble or a stone marble? Express your answer as a decimal rounded to four decimal places. Probability

Answers

The probability of selecting or having a marble to be either a blue marble or a stone marble is 0.8076.

Given, a bag contains 6 blue glass marbles, 5 yellow glass marbles,

12 blue stone marbles and 3 yellow stone marbles.

Probability of selecting a marble and having that marble to be either blue marble or a stone marble = ?

we know that,

Glass marbles:

n(B) = 6 and n(Y)= 5

Stone marbles:

n(B) = 12 and n(Y) = 3

Probability = Number of favorable outcomes/Total number of outcomes.

Probability of selecting a marble and having that marble to be either blue marble or a stone marble:

total number of blue marbles = 18

total number of stone marbles = 15

total number of marbles in the bag = 26

⇒ 18+15-12/26

⇒ 33-12/26

⇒ 21/26

= 0.8076

Hence the probability of selecting a marble and having that marble be either a blue marble or a stone marble is 0.8076.

Answer:

y = -800x + 294000

286,000

Step-by-step explanation:

To write the equation, you need the slope and the y-intercept.  

The slope is -800

You find the slope by the change in y over the change in x

[tex]\frac{288400 - 294000}{7 - 0}[/tex] = [tex]\frac{15600}{7}[/tex] = -800

Now we will find the y -intercept.  I will use the slope and the point (0, 294,000) to find this.  I could have used the other point given. They will both work.

slope (m) = -800

x = 0

y = 294000

y = mx + b

294000 = -800(0) = b

294000 = b

The equation is

y = mx + b

y = -800x + 294000

2014

y = -800x + 294000

y = -800(10) + 294000

y =-8000 + 294000

y  = 286,000

B. The output value of the function is 7 when the input value is 1
C. The output value of the function is 6 when the input value is x
D. The output value of the function is 8 when the input value is -2

Answers

The statement which is true is Option(D) The output value of the function is 8 when the input value is -2.

What do mathematical functions mean?

An expression, rule, or regulation that establishes a relationship between one variable (the independent variable) and another variable (the dependent variable) is referred to as a function in mathematics.

Given function:

H(x) = -x + 6

In Option A, the input value is -2 so the output of the function will be,

H(x) = -x + 6 = -(-2) +6 = 2+ 6 = 8 ,which is not equal to the given output value 4.

Hence, the statement is false.

Similarly in Option B and C, the input values are 1 and x.

H(x) = -x + 6 = -1 +6 = 5 ≠ 7

H(x) = -x + 6 ≠ 6

The given output values are not equal to the output values calculated.

So both statements are false.

In Option D the input value is -2 and the output value is 8 which is a correct statement as calculated in Option A.

three numbers have a sum of 180. the second number is 4 times the smallest number. the third number is 7 times the smallest number. what is the largest number?

Answers

X+4x+7x=180
12x=180
X=15
4x=60
7x=105
15+60+105=180

Answer:

105

Step-by-step explanation:

Let x, y and z be the 3 numbers in the order first, second and third

x + y + z = 180

Second number y is 3 times the smallest number and third number z is 7 times the smallest number. So smallest number has to be x

so y = 4x

z = 7x

x + y + z = x + 4x + 7x = 180

12x = 180

x = 15

Largest number = 7 x 15 = 105

A square has a side of length 1.6 yards. What is the area of the square inches? Round to the nearest tenth

Answers

Given that the side of the square is 1.6 yards.

The area of the square is

Substitute a=1.6, we get

[tex]A=1.6^2=2.56yards^2[/tex]

We need to convert yards to inches.

We know that

[tex]1\text{ yard =36 inches}[/tex]

Taking square on both sides, we get

[tex]1^2yard^2=36^2inches^2[/tex]

[tex]1yard^2=1296inches^2[/tex]

Multiplying by 2.56 on both sides, we get

[tex]1\times2.56yard^2=1296\times2.56inches^2[/tex]

[tex]2.56yards^2=3317.76inches^2[/tex]

Rounding to the nearest tenth, we get

Hence the area of the given square is 3317.8 square inches.

A die is rolled 200 times with the following results. Outcome 1 2 3 4 5 6 Frequency 32 36 44 20 30 38 What is the experimental probability of rolling the given result? a number more than 3

Answers

The experimental probability of rolling such that the number is more than 3 is 0.44.

The proportion of outcomes where a specific event occurs in all trials, not in a hypothetical sample space but in a real experiment, is known as the empirical probability, relative frequency, or experimental probability of an event.

When a dies is rolled 200 times, the results are:

Frequency     Outcome

     1                     32

     2                    36

     3                    44

     4                    20

     5                    30

     6                    38

Therefore,

The experimental probability that a number is more than 3 after rolling will be:

= The sum of outcome above 3 / total outcome

= ( 20 + 30 + 38 ) / ( 32 + 36 + 44 + 20 + 30 + 38 )

= 88/ 200

= 0.44

Hence, the probability that the number is more than 3 is 0.44.

Answers

The range of the function, y = 16x, is 60, where y is 960.

What is the range of a function?

The range of the function, y = 16x, are the possible values that x can assume to meet the value of y.

Usually, the range of a function is the output value.

Since the value of y = 960, the range of the function will be 60 (960/16).

The capacity of the dispenser = 960 ounces

The capacity of the juice containers = 16 ounces

The function that models the situation is y = 16x

Where y = 960

x = 60 (960/16)

Thus, the implication is that the range of the function or the number of 16-ounce containers that can fill the dispenser with a capacity of 960 ounces is 60.

Looking at the triangle, the reference angle is 30 degrees. The hypotenuse of the triangle is c. The opposite side of the triangle is 7 and the adjacent side is a.

We would determine the hypotenuse, c by applying the sine trigonometric ratio which is expressed as

Sin# = opposite side/hypotenuse

Sin 30 = 7/c

cSin30 = 7

c = 7/Sin 30 = 7/0.5

c = 14
