Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Answer:
I believe it would be - (n+4) x 2
Step-by-step explanation:
Answer:
2(n + 4)
Step-by-step explanation:
we take her number, n, and add 4
= n + 4
Then we double that. So that can either be 2n + 2(4) = 2n + 8, or 2(n + 4) which tells you to multiply everything in the parentheses by 2.
Please let me know if you have questions.

Estimate the solution of the system x+y=4 2x-y=6 by sketching a graph of each linear function. Then solve the system algebraically. Use your estimate to judge the reasonableness of your solution. The estimated solution is The algebraic solution is The solution is/is not reasonable because
Answer:
(10/3, 2/3)
Step-by-step explanation:
You may find it easier to write these two equations x+y=4 2x-y=6 in a column:
x+y=4
2x-y=6
Adding these together will eliminate y:
3x = 10. Then x = 10/3.
Substituting 10/3 for x in the first equation results in:
10/3 + y = 4
Clear fractions by multiplying all three terms by 3:
10 + 3y = 12
Then 3y = 2, and y = 2/3.
The solution is (10/3, 2/3)

On a hospital floor, 16 patients have a disease with a mortality rate of 0.1. Find the probability that two of them die. Round to three decimal places
Answer:
The probability that two of them
die is 0.257
Step-by-step explanation:
From the question, we have that the mortality rate is 0.1
So the probability that they will survive is 1-0.1 = 0.9
Now, we want to check that two will die
We are going you use the Bernoulli approximation of the Binomial theorem as follows
= nCr * p^n * q^(n-r)
where n = 16
r = 2
P = 0.1
q = 0.9
Substituting these values;
14 C 2 * 0.1^2 * 0.9^12
= 0.257
6. Kriti has a circular swimming pool in her house. The radius of the swimming
pool is22.5 cm. She walks one round every morning before diving in the pool.
How far does she walk around the pool every morning? *
70.65
141.3
35.33
282.6
Answer:
Total walk she did around the pool every morning = 141.3
Step-by-step explanation:
Given - Kriti has a circular swimming pool in her house. The radius of the swimming pool is 22.5 cm. She walks one round every morning before diving in the pool.
To find - How far does she walk around the pool every morning?
Proof -
Given that, the swimming pool is circular in shape.
So,
1 round of circle = Circumference of circle.
As we know that,
Circumference = [tex]2\pi r[/tex]
= [tex]2*\pi *22.5[/tex]
= 141.3
∴ we get
Total walk she did around the pool every morning = 141.3

A table cost $275. An LCD television set cost $325 more than the table.
Find the ratio of the cost of the LCD television set to the cost of the table.
Express the ratio in its simplest form.
Answer:
table cost=275
LCD television cost=325+275
= 600
[tex]ratio = \frac{600}{275} \\ = \frac{120}{55} \\ = \frac{24}{11} [/tex]

solve the following:
6(x-6)-5(x-7)=x+6
Answer:
[tex]no \: solution[/tex]
Step-by-step explanation:
1) Expand
[tex]6x - 36 - 5x + 35 = x + 6[/tex]
2) Simplify 6x - 36 - 5x + 35 to x - 1.
[tex]x - 1 = x + 6[/tex]
3) Cancle x on both sides.
[tex] - 1 = 6[/tex]
4) Since −1 = 6 is false, there is no solution.
No Solution
Hence, this equation have no solution.

In square units, what is the area of the blue sector in the figure above? Round to the nearest tenth.
Given:
A figure of a circle with radius 8. The central angle of the blue sector is 60 degrees.
To find:
The area of the blue sector.
Solution:
Area of a sector is:
[tex]A=\pi r^2\dfrac{\theta}{360^\circ}[/tex]
Where, r is the radius and [tex]\theta [/tex] is the central angle of the sector in degrees.
Putting [tex]r=8, \theta=60^\circ, \pi=3.14[/tex], we get
[tex]A=(3.14)\cdot (8)^2\cdot \dfrac{60^\circ}{360^\circ}[/tex]
[tex]A=(3.14) \cdot (64)\cdot \dfrac{1}{6}[/tex]
[tex]A=33.49333....[/tex]
Approximate the value to the nearest tenth.
[tex]A\approx 33.5[/tex]
Therefore, the area of the blue sector is about 33.5 sq. units.

Step-by-step explanation:
The product of two rational numbers is irrational.
Answer:
The statement is false.
Step-by-step explanation:
Here we need to remember some things:
Integer numbers are closed under multiplication.
This means that for two integers a and b, the product a*b is also an integer.
A rational number is a number that can be written as the quotient of two integer numbers.
An irrational number is a number that can't be written as the quotient of two rational numbers.
Now let's see the statement:
"The product of two rational numbers is irrational."
The product of two rational numbers is written as:
[tex]\frac{a}{b} *\frac{c}{d}[/tex]
Where a, c, b, and d are integers.
We can rewrite that product as:
[tex]\frac{a*c}{b*d}[/tex]
Because of the first property, we know that a*c is an integer, and b*d is also an integer, so here we have a quotient of two integer numbers, so this is a rational number.
Then the product of two rational numbers is a rational number.
Then the statement is false.

1) Hank is looking to sell his motorcycle. He compiles these prices from the newspaper for bikes just like his
$2,000; $ 16,900; $15,100; $14,500; and $17,000. Is it more reasonable for Hank to use the mean or the
median to get a reasonable estimated price for his bike?
Answer:
The median
Step-by-step explanation:
If you look at the sample section of the 5 different prices, you can see that $2,000 is very far away from the rest of the prices, which range from $14,000 to $17,000. This $2,000 is an outlier, and is likely not accurate in predicting reasonable prices for Hank's bike, so it should not be a factor in his decision or contribute to the mean value.
