y=3/2x-9
I need to find the x-intercept and the y-intercept with work plsss
Hi there!
x-int: (6, 0)
y-int: (0, -9)
y = 3/2x - 9
Begin by finding the x-intercept. The x-intercept is located where y = 0, therefore:
0 = 3/2x - 9
Isolate for x by adding 9 to both sides:
9 = 3/2x
Divide both sides by 3/2x:
9 * 2/3 = x
x = 6. Thus, the x-intercept is at (6, 0).
Find the y-intercept by finding the y-value at which x = 0:
y = 3/2(0) - 9
y = -9. The y-intercept is at (0, -9).
79 1/6% as a fraction
Answer:
475/6%
Step-by-step explanation:
I hope this helps.
The equivalent fraction of the percentage is A = 47401/600
What is a Fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given data ,
Let the fraction be represented as A
Now , the percentage value is given by P
And , the value of P = ( 79 1/6 ) %
We know that 1% is equivalent to 1/100, so we can write:
79 1/6% = 79 + 1/6% = 79 + 1/6 x 1% = 79 + 1/600
Now, we can convert the mixed number to an improper fraction by multiplying the whole number by the denominator and adding the numerator, then placing this over the denominator:
79 + 1/600 = (79 x 600)/600 + 1/600 = 47400/600 + 1/600
Combining these fractions, we get:
79 1/6% = 47401/600
Hence , 79 1/6% as a fraction is 47401/600.

First count up the amount of full squares, then you see the partially filled squares and try find the match for it to fill the square. It ends up being 24 squares, meaning 24 square feet. That multiplied by £5, as that is the cost of red wood, gives you the answer of £140

How much 9% saline solution should be mixed with 80 Cc of a 17% saline solution to produce a 13% saline solution?
Answer:
80 cc.
Step-by-step explanation:
We work in amounts of salt in the solutions:
0.09x + 0.17*80= 0.13(x+ 80) where x is the required volume of 9% solution.
0.09x + 13.6 = 0.13x + 10.4
13.6 - 10.4 = 0.13x - 0.09x
3.2 = 0.04x
x = 3.2 / 0.04
x = 80
A paint manufacturer wants to determine the average drying time of a new interior wall paint. For n = 50 test areas of equal size he obtained a sample mean drying time of ¯x = 63.3 minutes and a sample standard deviation of s = 8.4 minutes. (a) (5 points) Construct the 95% confidence interval for the true mean µ. (b) (5 points) Suppose the population has a normal distribution, construct the exactly 95% confidence interval for the true mean µ. (c) (5 points) Suppose the population has a normal distribution, construct the 95% prediction interval for a new observation.
Answer:
a) the 95% confidence interval for the true mean µ is 60.971, 65.629
The exact 95% confidence interval for the true mean µ is 60.971, 65.629
P (x`- ∝ s/√n<u <x`+ ∝ s/√n) = 0.95
Step-by-step explanation:
n= 50
x`= 63.3
s= 8.4 minutes
∝= 95%= ±1.96
The formula for calculating the confidence interval is:
x`± ∝ s/√n
Putting the values
x`± 1.96 s/√n
63.3 ± 1.96(8.4/√50)
63.3± 2.3287
60.971, 65.629
a) the 95% confidence interval for the true mean µ is 60.971, 65.629
b) Putting the values
x`± 1.96 s/√n
63.3 ± 1.96(8.4/√50)
63.3± 2.3287
The exact 95% confidence interval for the true mean µ is 60.971, 65.629
c) The prediction level tells that the drying time of the wall from 60.971 to 65.629 minutes must be in the range 95 % of the time.
And is given by
P (x`- ∝ s/√n<u <x`+ ∝ s/√n) = 0.95

What is equivalent to 0 = 2x2 - 16x – 18 when completing the
square?
Answer:
x = 1
x = -9
Step-by-step explanation:
(2x2 + 16x) - 18 = 0
2x2 + 16x - 18 = 2 • (x2 + 8x - 9)
x2 + 8x - 9
-9 + 1 = -8
-3 + 3 = 0
-1 + 9 = 8
2 • (x + 9) • (x - 1) = 0
2 = 0
x+9 = 0
x = -9
x-1 = 0
x = 1
x2 + 8x - 9 = 0
x2+8x = 9
(x+4) • (x+4) =
(x+4)2
x2+8x+16 = 25 and
x2+8x+16 = (x+4)2
(x+4)2 = 25
x = -4 + √ 25
x2 + 8x - 9 = 0
has two solutions:
x = -4 + √ 25
or
x = -4 - √ 25

2 days with no professional sports game.
3 forms of ratio --> a to b, a : b, a / b
1) Remember there are 365 days in a year.
Days without games to Days in a year --> 2 to 365
Days without games : Days in a year --> 2 : 365
Days without games / Days in a year --> 2 / 365
2) Now there is a plot twist. It ask days with games. To find that we need to subtract 365 - 2 = 363 days with games.
Days with games to Days in a year --> 363 to 365
Days with games : Days in a year --> 363 : 365
Days with games / Days in a year --> 363 / 365
3) Days with games to Days without games --> 363 to 2
Days with games : Days without games --> 363 : 2
Days with games / Days without games --> 363 / 2
