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.

A plane flew 390 nautical miles in 45 min. Find its average speed in knots ( nautical miles per hour)
Answer:
451.87 knots.
Step-by-step explanation:
Hope this helps
The average speed of the plane is 520 Knots.
What is the speed of an object?Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time
Given here: Distance travelled 390 nautical miles and t is 45 mins or 0.75 hours
Thus speed of the plane is = 390/0.75
= 520
Hence, The average speed of the plane is 520 Knots.

Three sides of a quadrilateral are the same length, g, The length of the fourth side is 7 inches,
The perimeter of the quadrilateral is 10 inches,
Write an equation that represents
the situation
7
3
7
Answer:
Step-by-step explanation:
Let s represent the length of each of the three sides mentioned. The length of the fourth side is 7 inches. Adding the lengths of the four sides together yields 10 inches: g + g + g + 7 = 10 (inches)
Then 3g + 7 = 10, or 3g = 3, or g = 1.
This equation is OK, but there's no solution, since 3g or just 3 is less than 7. With side lengths 1, 1, 1, 7, we cannot draw a quadrilateral.

Step-by-step explanation:
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.

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.

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

What is the average of 62 and 127
Answer:
Step-by-step explanation:
The answer is 94.5
Answer:
94.5
Step-by-step explanation:
You would find that by adding up all the numbers in a data set the dividing them by how many number are in the data.
For example:
127 + 62 = 189
And since there are two numbers in the data set, you would divide 189 by 2 and get 94.5 as your answer.

In the xy-plane, the graph of the equation y = x2 +2 intersects the x-axis in how many points?
O Zero
O One
Ο Two
O More than two
Answer:
0
Step-by-step explanation:
Here, we want to get the number of times the graph of the function intersects the x-axis
Mathematically we need to know the number of roots the function has
We can get this by the use of the discriminant
This is:
D = b^2 - 4ac
b is the coefficient of x which is 0 here
a is the coefficient of x^2 which is 1 here
c is the last number which is 2
So;
D = 0^2 -4(1)(2) = 0-8 = -8
the discriminant value is negative
This means there are no real roots
x-y plane is used for real numbers and thus since there are no real roots, the graph of the equation will not intersect any point on the x-axis

I d k
Step-by-step explanation:
5.75x10=57.50
57.5+11.5=69(nice)
69+5.75= 74.75
74.75+5.75=80.5
80.5+5.75= 86.25
