Hence, it is a binomial
Answer:
Linear expression
Step-by-step explanation:
First, simplify the expression.
Given expression: [tex]9p-10q+3-9p[/tex]
Collect like terms: [tex]9p-9p-10q+3[/tex]
Combine like terms: [tex]-10q+3[/tex]
As each term of the expression is either a numeric constant or a variable with no exponent, this is a linear expression.
It can also be called a binomial expression since the expression only contains two terms (the constant and the variable).

A bag of 10 Marbles has the following composition: Red – 3 Green – 4 Blue – 2 Yellow – 1 What is the Compound Probability of reaching in at random and extracting a Yellow marble followed by a Blue marble with NO REPLACEMENT?
The probability of extracting a Yellow marble followed by a Blue marble is 2/45 if the bag of 10 Marbles has the following composition: Red – 3 Green – 4 Blue – 2 Yellow – 1
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
Total number of marbles = 3+4+2+1 = 10
P(Yellow) = 1/10
P(Blue) = 4/9
Probability of extracting a Yellow marble followed by a Blue marble:
= (1/10)(4/9)
= 4/90
= 2/45
Thus, the probability of extracting a Yellow marble followed by a Blue marble is 2/45 if the bag of 10 Marbles has the following composition: Red – 3 Green – 4 Blue – 2 Yellow – 1

To find :-
To get the value of 'di in figure 3 and 4.
Figure 3
According to the figure, we know that it is a quadrilateral. It's all sides are at 90°.So we can assume that it can be rectangle. In the figure, length of one side is given and area of figure is given and we have the length of another side.Solution :-
Area of rectangle = length × width
area = 108 ft², length = 12 ft, width = x
[tex]108 = 12 \times x \\ \frac{108}{12} = x \\ 9 = x[/tex]
Therefore, the value of x in this figure is 9 ft.[tex] \\ [/tex]
Figure 4
According to figure, we finds out that it is quadrilateral as it has 4 sides. It has all parallel sides. We can assume that it is parallelogram as the sides which are facing each other are parallels. And here value of one side is given which is base and area is given, we have to find here is height.Solution :-
Area of parallelogram = base × height
Area = 96 cm², base = 16 cm, height = x
[tex]96 = 16 \times x \\ \frac{96}{16} = x \\ 6 = x[/tex]
Therefore, the value of x is 6 cm.NO LINKS!!!! Exponential Growth and Decay Part 3
Answer:
6. 14.9 years
7. 4.8 years
8. 28.91 years
Step-by-step explanation:
Exponential growth or decay is described by the function ...
y = a·b^t
where 'a' is the initial value, and 'b' is the growth (or decay) factor. The growth (or decay) factor is one added to the growth rate.
__
This equation can be solved for t to get ...
y/a = b^t . . . . . . . divide by a
log(y/a) = t·log(b) . . . . take logarithms
t = log(y/a)/log(b) . . . . divide by the coefficient of t
Note that the time period is in the same units as the growth rate. (If the growth rate is per quarter, then the value of t will be in quarters.)
__
6.The initial value is a=8000; the final value is y=35000; and the growth rate is 10%/4 = 0.025 per quarter. The above equation will give the time period in quarters.
t = log(35000/8000)/log(1+0.025) ≈ 59.77 . . . quarters
Anisha will have $35,000 after 59.77/4 = 14.9 years.
__
7.No loan payment period is given, so we assume that the $43000 represents the repayment of the entire loan. The growth rate is 6% per year. The time required for the loaned amount to accumulate to a value of $43,000 is ...
t = log(43,000/32,500)/log(1 +0.06) ≈ 4.80 . . . years
If the loan period is 4.80 years, Kevin will have paid 43,000 to pay it off.
__
8.The growth rate is 0.024/12 = 0.002 per month. The number of months to achieve the desired balance is ...
t = log(3200/1600)/log(1 +0.024/12) ≈ 346.92 . . . . months
The balance in the account will be $3200 after 346.92/12 = 28.91 years.

Additional comment
As a crude check on the answers, the "rule of 72" can be used. It says the doubling time is approximately 72 divided by the growth rate in percent. That is, a 10% growth rate will cause the value to double in approximately 72/10 = 7.2 years.
In the first problem, the value grows from 8000 to 35000, which represents a little more than 2 doublings (8000 to 16000 and 16000 to 32000). So, it is reasonable to expect the time period to be near 2 times 7.2 years, or 14.4 years. The value of 14.9 years is not unreasonable.

Therefore, Kevin will have paid $43,000 on the loan in 4 years and 10 months.

For the function defined by y = StartFraction 1 Over x squared EndFraction, if x is doubled, what is the effect on y?
a.
y is quartered
c.
y stays the same
b.
y is doubled
d.
y is tripled
Please select the best answer from the choices provided
Answer:
a. y is quartered.
Step-by-step explanation:
y=1/x^2
when x is doubled, the equation becomes:
y=1/(2x)^2=1/(4x^2)
Answer:
If we double x, then the new value of x becomes 2x. So we can find the effect on y by substituting 2x for x in the given function.
y = 1/x^2
When x is replaced by 2x, we get:
y' = 1/(2x)^2
= 1/4x^2
Therefore, y' = (1/4)y
So, if x is doubled, then y is quartered (option a is the correct answer)

Find the perimeter of a triangle that has the side lengths given below.
6 cm, 7√3 cm, √27cm
Give the answer as a radical expression in simplest form.
The perimeter of a triangle that has the side lengths is 6 + 10√3 cm
How to determine the perimeter?The side lengths are given as:
6 cm, 7√3 cm and √27 cm
The perimeter is the sum of the side lengths.
So, we have:
P = 6 + 7√3 + √27
Express 27 as 9 * 3
P = 6 + 7√3 + √(9 * 3)
Take the square root of 9
P = 6 + 7√3 + 3√3
Evaluate the sum
P = 6 + 10√3
Hence, the perimeter of a triangle that has the side lengths is 6 + 10√3 cm

What is Algebra?
Algebra is a branch of mathematics that deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they do not have predefined values.
These symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations in order to determine their values.
Given:
People who like the color purple = 187
Moreover, 45% of people prefer the color red.
Purple color enthusiasts = 100 - 45 = 55%
Let the total number of people polled be x.
So, 55% of x = 187
55/100x = 187
x= 18700/ 55

A bag contains 5 green and 3 white balls (the balls are identical in all respect except colour). A ball is drawn at random from the bag without looking into the bag. What is the probability of getting a green ball? Is it more or less than getting a white ball?
Answer:
Probability of getting a green ball is more than that of getting a white ball.
Step-by-step explanation:
There are in all (5+3= 8) outcomes of the experiment. There are 5 outcomes in favour of the event of getting a green ball as there are 5 identical green balls in the bag.
Therefore, P(a green ball) = 5/8
In the same way,P(a white ball) = 3/8
5/8 > 3/8Thus, clearly the probability of getting a green ball is more than that of getting a white ball.

Phu takes out a $2,400 discounted loan using a simple interest rate of 8% for a period of 18 months. What is the effective interest rate, re
Answer:
9.1
Step-by-step explanation:
To calculate the total interest payable, we use the formula
I=P0rt,
and substituting our values yields
I=$2,400×0.08×1812=$288.
Therefore the total amount he receives at loan drawdown is $2,400−$288=$2,112. To calculate the effective interest rate, we use to formula
A=P0(1+ret).
In this instance we have A=$2,400,P0=$2,112 (redefined from the value above) and t=1.5. We substitute into the formula to get
$2,400=$2,112(1+1.5re).
Solve for re.
24002112=1+1.5re
24002112−1=1.5re
24002112−11.5=re
This gives re=0.0909⋯=9.0909…%, which is 9.1%
