Answer:
y = 15x + 40
Step-by-step explanation:
(-3, -5) and (-2, 10)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(10 - (-5)) / (-2 - (-3))
Simplify the parentheses.
= (10 + 5) / (-2 + 3)
= 15 / 1
Simplify the fraction.
15/1
= 15
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 15x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-2, 10). Plug in the x and y values into the x and y of the standard equation.
10 = 15(-2) + b
To find b, multiply the slope and the input of x(-2)
10 = -30 + b
Now, add 30 to both sides to isolate b.
40 = b
Plug this into your standard equation.
y = 15x + 40
This is your equation.
Check this by plugging in the other point you have not checked yet (-3, -5).
y = 15x + 40
-5 = 15(-3) + 40
-5 = -45 + 40
-5 = -5
Your equation is correct.
Hope this helps!

Step-by-step explanation:
a company that receives the majority of its orders by telephone conducted a study to determing how long customers were willing to wait on hold before ordering a product. The length of waiting time was found to be a variable best approximated by an exponential distribution with a mean length of waiting time equal to 3 minutes. What proportion of customers having to hold more than 4.5 minutes will hang up before placing an order 0.51342 0.48658
Answer:
0.2231 = 22.31% of customers having to hold more than 4.5 minutes will hang up before placing an order
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
[tex]f(x) = \mu e^{-\mu x}[/tex]
In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.
The probability that x is lower or equal to a is given by:
[tex]P(X \leq x) = \int\limits^a_0 {f(x)} \, dx[/tex]
Which has the following solution:
[tex]P(X \leq x) = 1 - e^{-\mu x}[/tex]
The probability of finding a value higher than x is:
[tex]P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}[/tex]
The length of waiting time was found to be a variable best approximated by an exponential distribution with a mean length of waiting time equal to 3 minutes.
This means that [tex]m = 3, \mu = \frac{1}{3}[/tex]
What proportion of customers having to hold more than 4.5 minutes will hang up before placing an order?
This is:
[tex]P(X > 4.5) = e^{-\frac{1}{3}*4.5} = e^{-\frac{4.5}{3}} = e^{-1.5} = 0.2231[/tex]
0.2231 = 22.31% of customers having to hold more than 4.5 minutes will hang up before placing an order
At 8% sales tax, the total price of a color TV whose marked price is $425 is
A)$451
B)$459
C)$465.25
D)$425.75
Answer:
B 459
Step-by-step explanation:
After adding the sales tax of 8% to the marked price of the TV, the price of the TV will be equal to $459. Hence, option B is correct.
What is the Percentage?The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages.
In other terms, it is a relationship where the worth of the entire is always considered to be 100.
As per the given data in the question,
Sales tax on TV = 8%
Marked price of TV = $425
The total price of the TV, T = Tax + Marked Price
T = 8% × $425 + $425
T = $34 + $425
T = $459
Hence, the total price is $459.

Answer:
y = x² - 8x + 18
Step-by-step explanation:
vertex form based on vertex of (4,2) and point (2,6)
y = a(x - 4)² + 2
find 'a':
6 = a(2 - 4)² + 2
6 = 4a + 2
4 = 4a
a = 1
Convert y = (x - 4)² + 2 to standard form:
y = x² - 4x - 4x + 16 + 2
y = x² - 8x + 18

£150 is divided between Nick, June & Sushil so that Nick gets twice as much as June, and
June gets three times as much as Sushil. How much does June get?
Answer:
Amount June get = £45
Step-by-step explanation:
Given:
Total amount divided = £150
Amount Nick get = 2 x Amount June get
Amount June get = 3 x Amount Sushil get
Find:
Amount divided between Nick June and Sushil
Computation:
Assume;
Amount Sushil get = a
Amount June get = 3 x Amount Sushil get
Amount June get = 3a
Amount Nick get = 2 x Amount June get
Amount Nick get = 2 x 3a
Amount Nick get = 6a
Amount Sushil get + Amount June get + Amount Nick get = Total amount
So,
a + 3a + 6a = 150
10a = 150
a = 15
So,
Amount Sushil get = £15
Amount June get = 3a
Amount June get = 3 x 15
Amount June get = £45
Amount Nick get = 6a
Amount Nick get = 6 x 15
Amount Nick get = £90
