swer:
(0.0000009)³ (9 × 104)²/
(3, 000, 000)² (0.00243)
Answer:
The answer is 3.2 x 10-21.
Step-by-step explanation:
To solve this problem, we need to use the rules of exponents. The first step is to calculate the exponents for each number.
For 9 × 104, the exponent is 3 (9 × 104 = 90000).
For 3,000,000, the exponent is 2 (3,000,000 = 3000000).
For 0.00243, the exponent is -3 (0.00243 = 0.00000243).
Now, we can calculate the answer by multiplying the exponents:
3 × 2 × (-3) = -6
Then, we need to multiply the numbers together to get the final answer:
(9 × 104)² × (3,000,000)² × (0.00243) = 9 x 10-6 x 9 x 10-12 x 0.00243 = 3.2 x 10-21.

Part A:
Given that the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then
50% of x = 1200
⇒ 0.5x = 1200
⇒ x = 1200 / 0.5 = 2400
Therefore, the retail price of the mattress, before the discount is $2,400.
Part B:
Given that the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then
(100% + 150%) of p = 2400
250% of p = 2400
2.5p = 2400
p = 2400 / 2.5 = 960.
Therefore, the wholesale price, before the markup was $960.

the mean number of patients admitted per day to the emergency room of a small hospital is 2.5 . if, on any given day, there are only 1 beds available for new patients, what is the probability that the hospital will not have enough beds to accommodate its newly admitted patients?
This can be modeled as a Poisson distribution. The mean number of patients admitted per day is 2.5, so the Poisson parameter λ = 2.5. The probability that the hospital will not have enough beds on any given day is the probability that more than 1 patients will be admitted, which is given by:
P(X > 1) = 1 - P(X <= 1)
= 1 - (P(X = 0) + P(X = 1))
= 1 - (e^-2.5 * 0 + e^-2.5 / 1!)
= 1 - e^-2.5 * (1 + 2.5)

1) Given: AD // BC, AB // CD
Prove: DBC =~ BDA
(Use any proof method of your choice)
Since the angles in DBC and BDA are equal, we have:
DBC ≅ BDA
What is the Angle-Angle Similarity Theorem?
The Angle-Angle Similarity Theorem, also known as the AA Similarity Theorem, states that if two angles of one triangle are equal to two angles of another triangle, then the two triangles are similar.
Given: AD // BC, AB // CD
To prove: DBC =~ BDA
From the given, we have AD // BC and AB // CD.
This means that AD is parallel to BC and AB is parallel to CD.
Since AB is parallel to CD, corresponding angles are equal.
Let the angle BCD = x.
Then, angle BAD = x.
Since AD // BC, corresponding angles are equal.
Let the angle DCB = y.
Then, angle DAC = y.
Now, we can see that angle BDA + angle DAC = y + x.
And angle DBC + angle DCB = y + x.
Since the sum of the angles in a triangle is 180 degrees,
angle BDA + angle DAC + angle DBC = 180.
So, y + x + y + x = 180.
Therefore, 2y + 2x = 180.
And, y + x = 90.
Since the angles in DBC and BDA are equal, we have:

A density curve consists of the line segment connecting the points (0,1) and (0. 5,1) and the segment connecting (0. 5, 1) to the x-axis. A. Determine the coordinate point where the second segment crosses the x-axis. B. Determine the slope of that segment c. Determine the equation of the line containing this segment (y = mx + b) d. Calculate the probability P(X > 1)
The second segment crosses the x-axis at (1.5, 0), and the slope of the segment is -1
The area under any probability density curve is always 1 and it is used for finding out the probabilities for any random variable X taking a certain range of values.
Let the second segment crosses at (a,0) on the X-axis:
The area under the density curve is 1.
the given fig can be divided into a rectangle and a triangle by dropping a line from the point (0.5, 1) in the x-axis.
The coordinate point of the second segment at the x-axis:
Now,
1*0.5+1/2*1*(a-0.5)=1
1+(a-0.5)=2
a-0.5=2-1
a=1+0.5
a=1.5
Thus the second segment crosses the x-axis at (1.5, 0)
The slope of that segment c:
The slope of that segment=y₂-y₁/x₂-x₁
By considering the points (0.5, 1) and (1.5, 0)
We will have the slope as:
m=0-1/1.5-0.5
m=-1/1
m=-1
the equation of the line containing this segment:
The line passes from the point (0.5, 1)
y=mx+b is used to find the value of the intercept
so, substitute the values in the equation:
1=(-1)*0.5+b
1=-0.5+b
b=1.5
so, the equation for that line segment is
y=-x+1.5
x+y=1.5
To calculate the probability P(X > 1):
[tex]P(X > 1)=\int\limits\limits^1_1 {y} \, dx \\P(X > 1)=\int\limits^1_1 {(-x+1.5)} \, dx[/tex]
[tex]P(X > 1)=[\frac{-x^2}{2}+1.5x]_1^1^.^5\\\\P(X > 1)= (\frac{(-1.5)^2}{2} +1.5*1.5)-(\frac{-1^2}{2}+1.5*1)\\[/tex]

In investing $5,750 of a couple's money, a financial planner put some of it into a savings account paying 2% annual simple interest. The rest was invested in a riskier mini-mall development plan paying 12% annual simple interest. The combined interest earned for the first year was $475. How much money was invested at each rate?
The financial planner invested $4,737.50 in the mini-mall development plan and $1,012.50 in the savings account.
The amount invested in the savings account is equal to the total amount invested minus the amount invested in the mini-mall development plan. We can express this as an equation:
Total Investment - Investment in Mini-Mall Development Plan = Investment in Savings Account
Substituting the values given in the problem, we get:
$5,750 - Investment in Mini-Mall Development Plan = Investment in Savings Account
To solve for the Investment in Mini-Mall Development Plan, we need to use the combined interest earned for the first year. We can express this as an equation:
Interest Earned = (Investment in Savings Account x Interest Rate) + (Investment in Mini-Mall Development Plan x Interest Rate)
Substituting the values given in the problem, we get:
$475 = (Investment in Savings Account x 0.02) + (Investment in Mini-Mall Development Plan x 0.12)
Solving for Investment in Mini-Mall Development Plan, we get:
Investment in Mini-Mall Development Plan = ($475 - (Investment in Savings Account x 0.02))/0.12
Substituting the values given in the problem, we get:
Investment in Mini-Mall Development Plan = ($475 - ($5,750 - Investment in Mini-Mall Development Plan x 0.02))/0.12
Solving for Investment in Mini-Mall Development Plan, we get:
Investment in Mini-Mall Development Plan = $4,737.50

Similar Triangles - Side Splitter TheoremIf a line parallel to one side of a triangle intersects the other two sides, then this line divides those two sides proportionally.
Let x be the distance between 1st Street and 2nd Street along Pike Avenue.
As 1st Street and 2nd Street are parallel we can use the Side Splitter Theorem to calculate x:
[tex]\implies \sf x:300=40:40+160[/tex]
[tex]\implies \sf x:300=40:200[/tex]
[tex]\implies \sf \dfrac{x}{300}=\dfrac{40}{200}[/tex]
[tex]\implies \sf x=\dfrac{40}{200} \cdot 300[/tex]

Yes, it would be unusual to get a score of 0 on a binomial distribution with a mean of 2.5 and a standard deviation of 1.4. This is because the expected value of such a distribution is much higher than 0. The binomial distribution is a type of probability distribution which is used to describe the probability of a discrete event occurring a certain number of times in a given number of trials. The mean of the binomial distribution is the expected value of the events, while the standard deviation is a measure of how much the values of the events vary from the expected value. In this case, the expected value is 2.5, and the standard deviation is 1.4. This means that the probability of getting a score of 0 is quite low, since the expected value is so much higher than 0. Therefore, it would be considered unusual to get a score of 0 on this binomial distribution.
