What is the nearest integer to90

Answer:

Five Vases

Step-by-step explanation:

In this type of questions, you can't have a reminder. You would have to round up instead.

49 flowers / 10 per case = 4 remainder 9

Because you have a remainder you need to round 4 up to 5.

You need 5 vases.

The solution to the system of equations y = x - 4 and y = 4x + 2 is found by setting the two equations equal to one another and solving for x and y. The solution is (-1.5, -5.5).

The solution to the system of equations can be found by setting the two equations equal to each other, as they are both equal to y.

Equation 1: y = x - 4

Equation 2: y = 4x + 2

To find the point of intersection, set the two equations equal to each other: x - 4 = 4x + 2. Solve this for x to get that x = -1.5. Then, substitute x = -1.5 into one of the original equations to solve for y. If we use Equation 1, we get that y = -1.5 - 4 = -5.5. Therefore, the solution to the system of equations is (-1.5, -5.5).

The solution to the system of equations is [tex]\(x = -2, y = -6\)[/tex]. The point of intersection is [tex]\((-2, -6)\)[/tex].

The solution to a system of equations is the point where the graphs of the two equations intersect.

1. Set the Equations Equal to Each Other:

[tex]\[ x - 4 = 4x + 2 \][/tex]

2. Solve for x:

[tex]\[ -3x = 6 \][/tex]

[tex]\[ x = -2 \][/tex]

3. Substitute x back into one of the original equations to find y

[tex]\[ y = -2 - 4 = -6 \][/tex]

So, the  solution to the system of equations is [tex]\(x = -2, y = -6\)[/tex]. The point of intersection is [tex]\((-2, -6)\)[/tex].

Answer:

Part a) The constant of variation is [tex]r=0.0567[/tex] or [tex]r=5.67\%[/tex]

Part b) [tex]I=\$662.03[/tex]

Step-by-step explanation:

Part a) Find the constant of variation.

we know that

The simple interest formula is equal to

[tex]I=P(rt)[/tex]

In this linear direct variation the constant r represent the constant of proportionality

where

I is the Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

[tex]t=5/12\ years\\ P=\$3,892\\ I=\$92\\r=?[/tex]

substitute the values and solve for r

[tex]92=3,892(r(5/12))[/tex]

[tex]r=(92*12)/(3,892*5)[/tex]

[tex]r=0.0567[/tex]

Part b) what will the interest be after 3 years

in this part we have

[tex]t=3\ years\\ P=\$3,892\\ I=?\\r=0.0567[/tex]

substitute the values

[tex]I=3,892(0.0567*3)=\$662.03[/tex]

Answer:

0.3

Explanation:

We are given that:

Probability that a randomly chosen person lives in the East is 0.12

P(East) = 0.12 ..................> I

Probability that a randomly chosen person lives in the West is 0.18

P(West) = 0.18 ............> II

Now, we want to find the probability that the randomly chosen person lives in the East or West

To do this, we will use the following formula:

P(A or B) = P(A) + P(B)

Applying this rule to our givens:

P(East or West) = P(East) + P(West)

P(East or West) = 0.12 + 0.18

P(East or West) = 0.3

Hope this helps :)

Answer:

0.30

Step-by-step explanation:

The probability that a person chosen at random lives in the east region is 0.12

The probability that a person chosen at random lives in the west region is 0.18

The probability that a person chosen at random lives in east or west region;

[tex]P(E\:or\:W)=P(E)+P(W)[/tex]

This implies that;

[tex]P(E\:or\:W)=0.12+0.18[/tex]

[tex]P(E\:or\:W)=0.30[/tex]

Answer:

1/16 of the class are left handed boys but we do not know the amount of left handed girls so we cannot be sure.

Step-by-step explanation:

1/2 * 1/8 = 1/16

there is still no way to be sure of how many girls are left handed so you should probably make a note by the problem so the mistake on the test will be realized

By multiplying the fractions, we find that 1/16 of the students in Mrs. Wallace's science class are left-handed boys.

To solve this problem, we first need to understand that it involves fraction multiplication. We know that 1/2 of the students in Mrs. Wallace's science class are boys. Out of these boys, we know that 1/8 of them are left-handed.

When you want to find out a certain amount out of a fraction, you multiply fractions. In this case, 1/2 (the number of boys in class) times 1/8 (the fraction of boys who are left-handed) gives us 1/16. Therefore, 1/16 of the students in Mrs. Wallace's science class are left-handed boys.

Answer:

To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20

It has to be equated to zero and the values of x are the x-intercepts. So,

4x2 – 24x + 20 = 0

The resulting equation is a quadratic equation which can be solved by different methods. The solution is

x = 5, 1

The average therefore is:

(1+5/)2 = 3

The equation that represents the average of the x-intercept is 3.

Option C is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 9 is an equation.

We have,

f(x) = 4x² - 24x + 20

x-intercept is f(x) = 0.

Now,

4x² - 24x + 20 = 0

4(x² - 6x + 5) = 0

x² - 6x + 5 = 0

x² - (5 + 1)x + 5 = 0

x² - 5x - x + 5 = 0

x(x - 5) - 1(x - 5) = 0

(x - 1)(x - 5) = 0

x = 1 and x = 5

The average of x-intercept.

= (1 + 5)/2

= 6/2

= 3

Thus,

The average of the x-intercept equation is 3.

y = 20x

Step-by-step explanation:

We know that the car gets 20 miles per gallon and the number of miles traveled varies directly with the number of gallons of gas the tank holds.

We are to write a direct variation equation which represents this situation.

Direct variation is expressed in the form [tex]y=kx[/tex], where [tex]k[/tex] is the constant of variation.

So for this situation, the direct variation equation will be:

[tex]y=20x[/tex]

Answer: [tex]y=20x[/tex]

Step-by-step explanation:

By  definition, a direct variation equation has the form shown below:

[tex]y=kx[/tex]

Where k is a constant, y is the dependent variable and x is the independent variable.

According to the problem, you know that your car gets 20 miles per gallon. The number of miles traveled varies directly with the number of gallons of gas the tank holds.

Then, you can write the following direct variation equation that represents the situation:

y: The number of miles traveled

x:  the number of gallons of gas the tank holds.

k: 20 (Because your car gets 20 miles/gallon)

Then:

[tex]y=20x[/tex]

Answer:

a) Neither arithmetic nor Geometric

Explanation:

Since 99-89.9= 9.1, and 89.9 - 78.8 = 11.1, the sequence is not arithmetic.

Like wise 89.9/99=0.908 and  78.8/89.9 = 0.876 makes it not a geomtric sequence

Step-by-step explanation:

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

99, 89.9, 78.8, 68.7, . . . . .

Here,

[tex]a_1=99\\\\a_2=89.9\\\\a_3=78.8\\\\a_4=68.7[/tex]

But we can see that there is minor difference between the consecutive terms:

So, we will go for common difference whether it is same or not.

[tex]a_2-a_1=89.9-99=-9.1\\\\a_3=a_2=78.8-89.9=-11.1\\\\a_4-a_5=68.7-78.8=-10.1[/tex]

Their difference are not common.

So, It is neither geometric nor arithmetic.

Hence, Option 'a' is correct.

The function which is quadratic is:

           [tex]y-3x^2=3(x^2+5)+1[/tex]

We know that the general equation of a quadratic function is given by:

[tex]y=ax^2+bx+c[/tex]

where a , b and c are real numbers.

1)

[tex]y-3x^2=3(x^2+5)+1[/tex]

On solving we get:

[tex]y-3x^2=3x^2+15+1\\\\\\y=3x^2+3x^2+1+15\\\\\\y=6x^2+16[/tex]

Hence, the function is quadratic.

2)

[tex]y^2-7x=2(x^2+6)+7[/tex]

It is not a quadratic equation since we have a term as : [tex]y^2[/tex]

and hence the equation will not match the general equation of the quadratic function.

3)

[tex]y-2x^2=6(x^3+5)-4[/tex]

as it has a term of [tex]x^3[/tex]

Hence, it is a equation of a cubic function.

4)

[tex]y-5x=4(x+5)+9[/tex]

On solving we get:

[tex]y=9x+29[/tex]

It does not has any term of [tex]x^2[/tex]

Hence, the equation is not a quadratic function it represent a linear function.

The functions that are quadratic functions are [tex]y - 3x^2 = 3(x^2+5)+1\\[/tex] and [tex]y^2-7x= 2(x^2+6) +7[/tex].

The highest power of the polynomial is called the degree of the polynomial. The polynomial of degree two is called a quadratic polynomial.

According to the question,

1)

[tex]y - 3x^2 = 3(x^2+5)+1\\ y = 3x^2+ 15 + 3x^2 +1\\ y = 6x^2 +16[/tex]

Since the polynomial is of degree 1, It is a quadratic function.

2)

[tex]y^2-7x= 2(x^2+6) +7\\y^2= 2x^2 +7x+19[/tex]

The function is a quadratic function.

3)

[tex]y - 3x^2= 6(x^3+5)-4[/tex]

The degree of x is 3, so it is a cubic function.

4)

[tex]y - 5x = 4(x+5)+9 y \\= 4x + 5x+ 29y\\ = 9x+29[/tex]

The function is a linear function.

The functions which are quadratic equations are [tex]y - 3x^2 = 3(x^2+5)+1\\[/tex]and  [tex]y^2-7x= 2(x^2+6) +7[/tex] .
