Answer:

3/11

Step-by-step explanation:

You have to divide the factors, so you would multiply 2 times 9 over 3 times 22.  When you multiply them together you get 18 over 66. If you simplify that then you would get 3/11

Answer:

choice A.  9 is the degree.

Step-by-step explanation:

5х^5 + 8х^2 + 2х - 3x^9 - 8x^4 - 4х^5

to find the degree of this polynomial, you must look for the highest number in the exponent.

Here it appears to be 9  in the -3x^9 term

Option C) Smith have to pay $180 at the time of purchase.

Step-by-step explanation:

Mrs. Smith wants to use an installment plan to buy a washing machine and dryer set priced at $1,500.

We need to find the payment amount at the time of purchase.

This can be calculated by finding the 12% of the total price $1500.

Smith have to pay at the time of purchase = 12% of 1500

⇒ (12/100) × 1500

⇒ 12 × 15

⇒ 180

Hence, option C) $180 is the amount need to be paid by the Smith at the time of purchase.

Mrs. Smith will have to pay $180 at the time of purchase, not including taxes. This matches option B.

To find the down payment Mrs. Smith has to pay at the time of purchase, we need to calculate 12% of the total price of the washing machine and dryer set.

 The total price of the set is $1,500.

The down payment is 12% of this price.

To calculate the down payment, we multiply the total price by the down payment percentage:

 Down payment = Total price x Down payment percentage

Down payment = $1,500 x 12%

 First, we convert the percentage to a decimal by dividing by 100:

 12% = 12 / 100 = 0.12

Now we can calculate the down payment:

Down payment = $1,500 x 0.12

Down payment = $180

 Therefore, Mrs. Smith will have to pay $180 at the time of purchase, not including taxes. This matches option B.

Answer:2

Step-by-step explanation:2x2=4

Answer:

4 2/3

Step-by-step explanation:

(m-4) (3m-2)=0

Use the zero product property to find the zeros

m-4 = 0             3m-2 =0

m =4                    3m =2

                              m = 2/3

We want the sum of the zero's

4+ 2/3

4 2/3

From the quadratic equation (m-4) (3m-2)=0, we find the zeros of this equation are m=4 and m=2/3. The sum of the zeros is 4 + 2/3 = 4 2/3 or 14/3.

The subject of the question is related to the zeros of a quadratic equation. A zero of a function is also referred to as a root or solution of the equation, which is the value of m that makes the function equal to zero. This equation has the form of (m-4) (3m-2)=0. It has two zeros: m=4 from (m-4)=0 and m=2/3 from (3m-2)=0.  

Since the question asks for the sum of the zeros, we need to add these two solutions together: 4 + 2/3 = 4 2/3 or 14/3, which is our final answer.

Answer:

Expression for smallest doll: 12(7/10)^3

Step-by-step explanation:

Since the largest doll is 12 inches, and we need to find the expression for the smallest one, we would multiply 12 and 7/10. Secondly, there are 4 dolls. We need to find the smallest doll's height, so it would be 7/10 times 7/10 times 7/10. Which could be simplified to (7/10)^3.

For the second question, just solve the expression and that is the height of the smallest doll.

Answer:

Vicky's take home pay per month will be $1,580

Step-by-step explanation:

Given that her salary per annual i.e salary for the year = $24,000

Therefore salary per month would be $24,000/12 = $2,000.

From this, she must pay 15% income tax.

i.e 15% of salary

15/100 * 2000

= 0.15*2000

= $300.

Salary after paying tax = $2,000 - $300= $1,700.

Since, she must repay a loan at a rate of $120 per month we will reduct the loan from her salary,

$1,700 - $120 = $1,580

Vicky's take home pay per month will be $1,580

Answer: Vicky's take home pay per month is $1,580

Step-by-step explanation: If Vicky's annual gross salary (salary before any deductions) is given as 24000, then her monthly gross salary is derived as;

Salary Per month = 24000/12

Salary per month = 2000

She must pay 15 percent income tax and this derived as follows;

Income tax = 2000 x 0.15

Income tax = 300

Therefore her salary after tax deduction is derived as follows;

Salary after tax = 2000 - 300

Salary after tax = 1700

However, she must repay a loan (after tax deduction) at a rate of 120 per month, which is now derived as follows;

Salary after loan repayment = 1700 - 120

Salary after loan repayment = 1580

Therefore the calculations show that her take home pay after all adjustments comes down to $1,580 per month.

Answer:

P(E|F)=60%  P(E)=60%  Events E and F are independent

Step-by-step explanation:

I took it and got it right

The events E (being blond) and F (being a junior) are not independent because P(E|F) = 30% does not equal P(E) = 60%.

To determine whether the events E (being blond) and F (being a junior) are independent, we compare the probability of E given F, denoted as P(E|F), to the probability of E. If P(E|F) is equal to P(E), the two events are independent. Using the table, we first calculate P(E|F). Since 30% of juniors are blond, we have P(E|F) = 30%. Next, we determine P(E) by looking at the total percentage of students who are blond, which is 60%. Now, we compare P(E|F) with P(E).

If the events were independent, the probability of a student being blond should not change based on whether they are a junior. However, since P(E|F) = 30% which is different from P(E) = 60%, events E and F are not independent.

We are told that each person flips a coin 200 times. We know that a coin has two options when heads or tails fall, therefore, the results between Amir and Marvin are compared with the number of heads and the number of tails that each one obtained.

The theoretical probability says that out of 200 times a coin is flipped by having 50% heads or tails come out, 100 must be heads and 100 must be tails, theoretically obviously speaking.

Therefore with these values it would be the comparison.

Answer:12, 12, 16, 22

Step-by-step explanation:

1. The number that occurs most is the mode

2. The range is the difference between the highest number and the lowest number.

3. The median in this case is the mean of the two middle numbers

A possible set of 4 numbers that fulfil the conditions of having a mode of 12, a median of 14 and a range of 10 could be: 11, 12, 12, 21.

In this problem, we need to find 4 numbers that meet the given statistical conditions - A mode of 12, a median of 14, and a range of 10. The mode is the most frequently occurring number. As there are only 4 numbers, for 12 to be the mode, it must appear at least twice. The median is the middle value when numbers are put in ascending order, so the middle numbers in our 4 number series must average to 14. Finally, the range is the difference between the largest and smallest numbers, which is stated as 10.

Using the above conditions, an example set could be: 11, 12, 12, and 21. Here, 12 is the mode (appears most frequently), 14 is the median (average of the two middle numbers 12 and 12) and 21-11 gives a range of 10.

Answer:

x=-36

Step-by-step explanation:

Add the 7/2x +1/2x to be 8/2x which means that it'll be 4x=18=9/2

then subtract 9/2x on both sides so itll be

[tex]4x=18+\frac{9}{2} x[/tex]

-9/2x       -9/2x

[tex]-\frac{1}{2} x=18[/tex]   because if you do 8/2-9/2 it's -1/2

then multiply the reciprocal to both sides so

[tex](\frac{2}{-1})(-\frac{1}{2}x)=(\frac{2}{-1})(18)[/tex]

which then cancels out -1/2 and makes it

x=-36

The interval of points less than -4 is represented as (-∞, -4) in interval notation. This represents all the numbers to the left of -4 on the number line, not including -4.

In Mathematics, when we refer to the interval of points that are less than a given number, we are discussing a range on a number line. For the question at hand, the interval of points that are less than -4 will consist of all numbers to the left of -4 (not including -4 itself). In interval notation, we typically express this as (-∞, -4). Here, the parenthesis ( as opposed to a bracket [ ) signifies that -4 is not included in our interval. Infinity ( ∞ ) is used to show that the range extends indefinitely.

Answer:

Step-by-step explanation:

It makes 19 copies in 3 minues and 15 seconds

3 minutes and 15 seconds is 195 seconds

195 ÷ 19 = 10 approximately which means the machine makes 1 copy every 10 seconds and 6 copies per minute

Answer: 5.846 ~ 6copies

Step-by-step explanation:

A copy machine makes 19copies in 3minutes and 15secs

How many copies in per minute

I.e how many copies per minute

Looking at this,

Convert the 3mins 15secs all into mins

I.e convert the 15secs into mins

Remember that 60secs makes 1mins

So 15secs will make x

Cross multiply

15secs ×1= 60secs ×x

X= 15/60

X= 0.25mins

Add to the already 3mins

That makes

=3mins+0.25mins

=3.25mins

Now,

19copies done in 3.25mins

Let the unknown copies be h

19copies in 3.25mins

H copies in 1mins

Cross multiply

H×3.25mins=19×1mins

3.25H=19

H=19/3.25

H= 5.846copies

H=~6copies

So the copying machine makes approximately 6copies per minute

Answer:

Im not to sure but 93

Step-by-step explanation:

if the width is 79, then 79 plus 79 is 158

and 344 minus 158 is 186

and 186 divided by two is 93

hope that helped :)

Answer:

93 yards

Step-by-step explanation:

When you have a rectanglular field, you can double the width, and then double the length, then add them together to get the perimeter.

If the perimeter is 344, and the width is 79, we can double it to find the value of 2 of the sides, because, if you are on a rectangular field, double the width, then you have to add it to the lengt doubled.

79+79=158

We can subtract 344 by 158 to get the doubled version of the length. After we find the doubled version of the length, we have to divide that by 2.

344-158=186

Now, like I said, we have to divide 186 by 2 to find how much the length is.

186/2=93

The length is 93 yards.

Answer:

-2x+3y=7

or

2x-3y= -11

Step-by-step explanation:

-2x+3y= -4, which is Ax+By=C

A=-2 B=3 C=-4

m(slope)= -A/B

m= -(-2)/3

m= 2/3

y-y1= m (x-x1)

y-3= 2/3 (x-1)

Multiply by 3 cancels out the fraction

3y-9= 2 (x-1)

Distributive property

3y-9= 2x-2

-2x+3y-9= -2

From here it could go 2 ways:

1. -2x+3y= 7

or

2. 2x-3y+9= -2

so

2x-3y= -11

Answer:

The value of c is -8

Step-by-step explanation:

Given

[tex]\frac{-3}{4} x^2 + 2 = 0[/tex]

Required

The value of c, when written in a general form.

The general form of a quadratic equation is written as ax² + bx + c = 0

To get the general form of [tex]\frac{-3}{4} x^2 + 2 = 0[/tex], we start by converting the fraction to whole number.

This is done by multiplying both sides of the equation by the denominator of the fraction (4)

Multiply through by 4; This gives us

[tex]4 * \frac{-3}{4} x^2 + 4 * 2 = 4 * 0[/tex]

[tex]-3x^2 + 8 = 0[/tex]

From the general form of a quadratic equation, ax² + bx + c = 0 , it'll be observed that a is positive and by comparison a = -3 (in [tex]-3x^2 + 8 = 0[/tex])

So, we have to convert -3 to a positive integer by multiplying both sides of the equation by -1. This gives

[tex]-1 * -3x^2 + -1 * 8 = -1 * 0[/tex]

[tex]3x^2 - 8 = 0[/tex]

Writing [tex]3x^2 - 8 = 0[/tex] in a more general form, we have

[tex]3x^2 + 0x - 8 = 0[/tex]

By comparing ax² + bx + c = 0  to [tex]3x^2 + 0x - 8 = 0[/tex]

a = 3

b = 0

c = -8

Hence, the value of c is -8

The value of "c" in the quadratic equation -3/4x^2 + 2 = 0, when written in the general form ax²+bx+c = 0, is 2.

The question asks, "When the following quadratic equation is written in general form, what is the value of "c"? -3/4x^2 + 2 = 0". In the general form, a quadratic equation is presented as ax²+bx+c = 0. To identify the value of c in this equation, we need to compare it to the general form. The given equation, -3/4x² + 2 = 0, already matches the general form where a = -3/4 and b = 0 (since there is no x term), leaving us with +2 as the constant term. Therefore, the value of c is 2.
