Answer:

Step-by-step explanation:
LOL its ok :)
Answer:
10000
Step-by-step explanation:
When we multiply two numbers, the answer we get is called 'product'. The number of objects in each group is called 'multiplicand,' and the number of such equal groups is called 'multiplier'. In math, to multiply means to add equal groups. ... The two factors and the product are parts of a multiplication problem. In the multiplication problem, 6 × 9 = 54, the numbers 6 and 9 are the factors, while the number 54 is the product. The four basic mathematical operations--addition, subtraction, multiplication, and division--have application even in the most advanced mathematical theories. Thus, mastering them is one of the keys to progressing in an understanding of math and, specifically, of algebra.

Find the length of JL
15
None of the other answers are correct
12
3
Answer:
D: 12
Step-by-step explanation:
The entire segment KI is composed of the segments KJ and JI. So:
[tex]KI=KJ+JI[/tex]
We know that KI is 15.
KJ is (2x-15) and JI is (2x-6). Substitute:
[tex]15=(2x-15)+(2x-6)[/tex]
Solve for x. Combine like terms:
[tex]15=4x-21[/tex]
Add 21 to both sides:
[tex]4x=36[/tex]
Hence, the value of x is:
[tex]x=9[/tex]
We know that JI is 2x-6.
We will substitute 9 for x to find JI. So:
[tex]JI=2(9)-6=18-6=12[/tex]
Hence, our answer is D.
A stock price is $100. Volatility is estimated to be 20% per year. What is the an estimate of the standard deviation of the change in the stock price in one week?
Answer: if I’m correct the answer is $0.38
Step-by-step explanation:
The estimate of the standard deviation of the change in the stock price in one week is $2.77.
What is the standard deviation?It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
We have:
Stock price = $100
Volatility = 20% ⇒ 0.20
We know the standard deviation of change in the stock price is given by:
[tex]\rm = \frac{stock \ price \times implied \ volatility \times \sqrt{days \ to \ change} }{\sqrt{365} }[/tex]
[tex]\rm = \frac{100\times 0.20\times\sqrt{7} }{\sqrt{365} }[/tex] (1 week = 7 days)
= 5.2343×0.20×2.646
= 2.7699 ≈ $2.77
Thus, the estimate of the standard deviation of the change in the stock price in one week is $2.77.

Micro Knowledge sells 5 times as many computers as Morse Electronics. The difference in sales between the two stores is 20 computers. How many computers did each store sell?
Answer:
Morse electronics sells 5 computers
Micro knowledge sells 25 computers
Step-by-step explanation:
The computation is shown below:
Let us assume the morse electronics computer be x
So the micro knowledge computers be 5x
And, the difference between them is 20
Now the equation is
5 x - x = 20
4x = 20
x = 5
Hence, the morse electronics sells 5 computers
While on the other hand the micro knowledge sells
= 5 × 5
= 25 computers

Answer:
its B
Step-by-step explanation:
The graph that would most likely be associated with the given model is an option(b).
What is a graph?A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
The regression equation is:
n(t) = 3.53t^2 - 33.04t + 117.56
The above regression equation is a quadratic function and non-linear.
thus, the graph must represent a non-linear relationship.
From the graphs, the only graph of the option (b) represents a quadratic function.
Other given options are either linear models or exponential.
Hence, the graph that would most likely be associated with the given model is an option(b).

A rancher has 1000 feet of fencing in which to construct adjacent, equally sized rectangular pens. What dimensions should these pens have to maximize the enclosed area?
Answer:
The dimensions that will maximize the enclosed area of the pen is 250 ft by 250 ft
Step-by-step explanation:
we have the perimeter as 1000
So the sum of the lengths will be
1000/2 = 500
The dimensions that will maximize these pens will be such that they will have equal values
Mathematically, that will be 500/2 = 250 by 250

B. O 3 x 25.90 +4= 81.70
C.3 x (25.90 + 4) = 89. 70
D.O3 (25.90 + 4) = 81. 70
Answer:

Since Roberto bought 3 gifts, which are each $25.90, that would mean it would be 3×25.90. Plus, he bought himself a treat would would be a +4.
George the Pigeon travels the same distance of 72 miles
in 4 hours against the wind as he does traveling 3 hours
with the wind in the local skies. What is the speed of
George the Pigeon in still air and the speed of the wind?
Answer:
The speed of George the Pigeon in still air = 21 miles/hr
The speed of air = 3 miles/hr
Step-by-step explanation:
Let the speed of George the Pigeon in still air = [tex]u[/tex] miles/hr
Let the speed of air = [tex]v[/tex] miles/hr
Distance traveled = 72 miles
Relative speed against the wind = [tex](u-v)[/tex] miles/hr
Time taken against the wind = 4 hours
Relative speed with the wind = [tex](u+v)[/tex] miles/hr
Time taken against the wind = 3 hours
Using the formula:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
[tex]u-v=\dfrac{72}{4}\\\Rightarrow u-v=18 ..... (1)[/tex]
[tex]u+v=\dfrac{72}{3}\\\Rightarrow u+v=24 ..... (2)[/tex]
Adding (1) and (2):
[tex]2u=42\\\Rightarrow u = 21\ miles/hr[/tex]
By equation (1):
[tex]v = 21-18\\\Rightarrow v = 3\ miles/hr[/tex]
Therefore, the answer is:
The speed of George the Pigeon in still air = 21 miles/hr
The speed of air = 3 miles/hr

A certain lottery requires players to select 7 different numbers, in any order, from 1 to 51 inclusive. How many different sets of 7 numbers can be chosen?
Answer:
[tex]Selection = 345025251[/tex]
Step-by-step explanation:
Given
[tex]Total = 51[/tex]
[tex]Numbers = 7[/tex]
Required
Determine number of selection
It's important that
- The first number can be any of the 51 numbers
- The second number can be any of the 51 numbers
- The third number can be any of the 51 numbers
- The fourth number can be any of the 51 numbers
And so on
Hence, number of selections is:
[tex]Selection = 51 * 51 * 51 * 51 * 51[/tex]
[tex]Selection = 51^5[/tex]
[tex]Selection = 345025251[/tex] ways

A waterfall has a height of 1700 feet. A pebble is thrown upward from the top of the falls with an initial velocity of feet per second. The height of the pebble h in feet after t seconds is given by the equation h=-16t^2+24t+1700 . How long after the pebble is thrown will it hit the ground?
PLEASE HELPPPPP
Answer:
[tex]t = 11.085[/tex]
Step-by-step explanation:
The expression is given as:
[tex]h=-16t^2+24t+1700[/tex]
Required
Determine how long it will hit the ground
When the pebble is on the ground, this implies that h = 0
So, we have that:
[tex]h=-16t^2+24t+1700[/tex] becomes
[tex]0=-16t^2+24t+1700[/tex]
Reorder
[tex]-16t^2+24t+1700 = 0[/tex]
Multiply through by -1
[tex]16t^2-24t-1700 = 0[/tex]
Solve using quadratic formula [tex]ax^2 + bx + c = 0[/tex]:
[tex]t = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = 16[/tex] [tex]b = -24[/tex] [tex]c = -1700[/tex]
So, we have:
[tex]t = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]t = \frac{-(-24) \± \sqrt{(-24)^2 - 4*16*(-1700)}}{2*16}[/tex]
[tex]t = \frac{24 \± \sqrt{576 + 108800}}{32}[/tex]
[tex]t = \frac{24 \± \sqrt{109376}}{32}[/tex]
[tex]t = \frac{24 \± 330.72}{32}[/tex]
[tex]t = \frac{24 + 330.72}{32}[/tex] or [tex]t = \frac{24 - 330.72}{32}[/tex]
[tex]t = \frac{354.72}{32}[/tex] or [tex]t = \frac{-306.72}{32}[/tex]
[tex]t = 11.085[/tex] or [tex]t = -9.585[/tex]
But time can't be negative.
So: [tex]t = 11.085[/tex]
Hence, it will take 11.085 seconds to hit the ground

What is the rat pop in 1990?
What does the model predict the rat pop was in the year 2005?
Answer:
Pop in 1990 = 81 million rats
Pop in 2005 = 127 million rats
Step-by-step explanation:
Given the function, the population of rats in 1990 is when we replace t with "0" which strictly gives the coefficient 81 that represents 81 million rats.
The rat population in 2005 is given by the formula when t = 15
This is: approximately 127 million rats.
