6. When a company receives an order, there is a probability of 0.42 that its value is over $1000. If an order is valued at over $1000, then there is a probability of 0.63 that the customer will pay with a credit card. a. What is the probability that the next three independent orders will each be valued at over $1000
Answers
Answer:
0.074088
Step-by-step explanation:
Let
A:Value of order over $1000
B:Customer pay with credit card
We are given that
Probability of value of order over $1000,P(A)=0.42
If an order is valued at over $1000, then the probability that the customer will pay with a credit card, P(B/A)=0.63
We have to find the probability that the next three independent orders will each be valued at over $1000
We know that
When two two events A and B are independent then
[tex]P(A\cap B)=P(A)\cdot P(B)[/tex]
Using the formula
The probability that the next three independent orders will each be valued at over $1000=[tex]0.42\times 0.42\times 0.42[/tex]
The probability that the next three independent orders will each be valued at over $1000=0.074088
The income and the costs of a company are given by the equations below, where x is the number of units sold, in hundreds, and y is the total dollar amount, in thousands.
Income: y = -0.5x2 + 6x + 90
Costs: y = 2.5x + 30
Determine which of the following would be a viable solution for the number of units sold that would cause the income and the costs to be the same.
a. 700 units sold and a value of $47,500
b. 800 units sold and a value of $32,800
c. 1,000 units sold and a value of $25,000
d. 1,500 units sold and a value of $67,500
Answers
Answer:
D
Step-by-step explanation:
The income is given by:
[tex]y=-0.5x^2+6x+90[/tex]
And the costs are given by:
[tex]y=2.5x+30[/tex]
Where x is the number of units sold, in hundreds, and y is the total dollar amount, in thousands.
We want to find a viable solution for the number of units sold that would cause the income and cost to be the same.
So, we can set the two equations equal to each other and solve for x. Therefore:
[tex]-0.5x^2+6x+90=2.5x+30[/tex]
Subtract 2.5x and 30 from both sides:
[tex]-0.5x^2+3.5x+60=0[/tex]
Remove the decimals and the negative of the leading coefficient by multiply both sides by -2:
[tex]x^2-7x-120=0[/tex]
Factor. We can use -15 and 8. So:
[tex](x-15)(x+8)=0[/tex]
Zero Product Property:
[tex]x=15 \text{ or } x=-8[/tex]
The answer must be positive since we cannot sell negative units.
So, the value of x is:
[tex]x=15\text{ or } 1,500 \text{ units}[/tex]
Then using either equation, the value will be:
[tex]2.5(15)+30=67.5=\$67,500[/tex]
Our answer is D.

d. 1,500 units sold and a value of $67,500

What does the statement “ The shortest distance between two points is the straight line between them” have to do with the Triangle Inequality Conjecture?
Do not answer this with one, none, or a ridiculous response please... this is serious
Answers
Answer:
https://geometryhelp.net/triangle-inequality-theorem/
Step-by-step explanation:
This is from that site. Visit it and you may find what you're looking for.
If we want to go from point A to point B, getting there through any intermediate point C, which is not on the straight line between A and B, is going to be longer. This should seem intuitively correct. But we will prove it formally.
Where do triangles come into this? Imagine that the line AB is a side of a triangle, ΔABC. Going from A to B is the straight, short way. Going there by first going to another point, C (which is the side AC) and then from C to B (which is the side CB) is going to be longer.

hours. The distance from Sheffield to Bude is 315 miles.
What is my average speed?
4) The distance from Leeds to London is 210 miles. The train

a) What is the average speed of a journey from Sheffield to
Land’s End that takes 8 hours 45 minutes?
b) If Sam covered the distance at an average speed of 63
mph, how long would it take him?
Answers
Answer:
Step-by-step explanation: Speed is distance an object travelled per unit time.
It is represented by letter v and can assume various units.
1) [tex]v=\frac{distance}{time}=\frac{d}{t}[/tex]
[tex]v=\frac{90}{5}[/tex]
v = 18 miles per hour
Her average speed is 18 mph.
2) Rearraging formula for distance:
d = v.t
d = 70 * 4
d = 280 miles
You would travel 280 miles.
3) [tex]v=\frac{d}{t}[/tex]
[tex]v=\frac{315}{6}[/tex]
v = 52.5 mph
My average speed is 52.5 mph.
4) Rearranging formula to determine time:
[tex]t=\frac{d}{v}[/tex]
[tex]t=\frac{210}{90}[/tex]
t = 2.34 hours
It will take 2 hours and half to arrive in Leeds. So, we will be expected to arrive at 12:04.
5) The unit change but the way of calculating time is the same.
[tex]t=\frac{2000}{4}[/tex]
t = 500 s
or t = 8.34 minutes
It will take, for an athlete to run 2000m, 8.34 minutes.
6) a) All units must match, so for a speed in mph:
45 minutes is 0.75 hours. Total time is 8.75 hours.
[tex]v=\frac{420}{8.75}[/tex]
v = 560 mph
The average speed is 560 mph.
b) [tex]t=\frac{d}{v}[/tex]
[tex]t=\frac{420}{63}[/tex]
t = 6.67 hours
Sam will take 6.67 hours to covered the distance.

Answers
Answer:
414Step-by-step explanation:
Let the number be aba as it is a palindrome
It divisible by 18, so it is an even number with sum of digits divisible to 9
2a + b = 9kIt is one less than a multiple of 5:
aba = 100a + 10b + a = 101a + 10bMultiple of 5 will end with 0 or 5, it has to be 5 as a is even, then:
a = 5 - 1 = 4The number 4b4 is divisible by 9 only if b = 1:
2*4 + b = 9k ⇒ b = 1So the number is:

Matthew makes a drink using lemonade and orange juice.
210ml of his drink was lemonade
140ml of his drink was orange juice
Rosie makes more of the drink for a party using the same ratio of lemonade to orange juice.
Rosie uses 6 litres of lemonade.
How much orange juice does Rosie use?
Answers
Answer: 4
Step-by-step explanation:
Matthew makes a drink using lemonade and orange juice.
210ml of his drink was lemonade
140ml of his drink was orange juice
Based on the above, we can see that the ratio of lemonade to orange juice is 3:2. 70 is a common factor to 210 and 140. 210/70 = 3 while 140/70 = 2.
Therefore, since Rosie uses 6 litres of lemonade, the amount of orange juice that Rosie use will be:
= 6 × 3/2
= 4
Rosie needs 4 litres of orange juice.
Nicole can buy 3 pounds of Luce suppose an orchard for $4.95 or she can buy a 25 ounce bag of apples from the store for $3.79 which is the better deal?
Answers
9514 1404 393
Answer:
orchard apples are lower-cost
Step-by-step explanation:
3 pounds is 48 ounces, so the equivalent to the store offering might be about 24 ounces for $4.95/2 ≈ $2.48.
This is substantially less cost per ounce than 25 ounces for $3.79. (24 and 25 are very near, but $2.48 and $3.79 are not.)
Orchard apples are the better deal.
