You buy a pair of jeans for 25% markdown from $32.00. The sales tax is 6%. How much will you pay for the jeans?
Answer:
$25.44
Step-by-step explanation:
Although the starting price of the pair of jeans is $ 32, it is 25% off. Thus, 75% of its initial value (100-25) is being paid, with which the pre-tax price is determined as follows:
32 x 0.75 = X
24 = X
In turn, at that discounted price, 6% must be calculated as sales tax, with which the final price is determined through the following calculation:
24 x 1.06 = X
25.44 = X
Therefore, the price to pay for the pair of jeans is $ 25.44.
Answer:
$25.44

Write an equation of the line that passes through (-3.3) and is perpendicular to the line 2y=8x-6
Answer:
y= -.25x+2.25
Step-by-step explanation:
Answer:
y = - [tex]\frac{1}{4}[/tex] x + [tex]\frac{9}{4}[/tex]
Step-by-step explanation:
(-3, 3)
2y = 8x - 6 ⇔ y = 4x - 3
y - 3 = - [tex]\frac{1}{4}[/tex] (x + 3)
y = - [tex]\frac{1}{4}[/tex] x + [tex]\frac{9}{4}[/tex]
What is the Domain and Range?
(see TWO photos)
PLEASE HELP
Answer:
The domain (x values) is negative infinity to positive infinity since the graph keeps going in both directions ( left and right ) and the range (y values) is -1 to positive infinity since the graph starts at vertex (-1, -4) and continues infinitely upward.

(2x+3y=23)(3x+4y=15)using ellimination method.
Answer:
x = -47, y = 39
Step-by-step explanation:
2x+3y=23 →equation 1
3x+4y=15 →equation 2
by elimination method,
(2x+3y=23) × 4
(3x+4y=15) × 3
8x + 12y = 92
(-) (-) (-)
9x + 12y = 45
---------------------
-1x + 0 = 47
-x = 47
x = -47
substitute x=-47 in equation 1
2(-47) + 3y = 23
-94 + 3y = 23
3y = 23 + 94
3y = 117
y = 117/3
y = 39
therefore, x = -47 and y = 39

You are a researcher studying the lifespan of a certain species of bacteria. From a previous study, it was found that the standard deviation was 5.6 hours. You would like to estimate the mean lifespan for this species of bacteria to within a margin of error of 0.45 hours at a 98% level of confidence. What sample size should you gather to achieve a 0.45 hour margin of error?
Answer:
The sample size is [tex]n = 841 [/tex]
Step-by-step explanation:
From the question we are that
The standard deviation is [tex]\sigma = 5.6 \ hours[/tex]
The margin of error is [tex]E = 0.45[/tex]
From the question we are told the confidence level is 98% , hence the level of significance is
[tex]\alpha = (100 - 98) \%[/tex]
=> [tex]\alpha = 0.02[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 2.33[/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2[/tex]
=> [tex]n = [2.33 } * 5.6}{0.45} ] ^2[/tex]
=> [tex]n = 841 [/tex]

Find the equation of a line (in y = mx + b form) through the point (-2,5) with an angle of
inclination of 45°.
Answer:
y = x + 7
Step-by-step explanation:
The equation of a line in slope - intercept form is expressed as y = mx+c
m is the slope
c is the intercept
Get the slope m;
m = tan theta
m = tan 45
m = 1
Get the intercept c;
Substitute m = 1 and (-2, 5) into the equation y = mx+c and get c;
5 = 1(-2)+c
5 = -2+c
c = 5+2
c = 7
Get the required equation;
y = 1(x)+ 7
y = x + 7
Hence the equation of the line is y = x+7

If you have a demand function of Qd=48-9P and a supply function of Qs=-12+6P,
what would the equilibrium QUANTITY be?
Answer:
The equilibrium quantity is 26.4
Step-by-step explanation:
Given
[tex]Q_d = 48 - 9P[/tex]
[tex]Q_s = 12 + 6P[/tex]
Required
Determine the equilibrium quantity
First, we need to determine the equilibrium by equating Qd to Qs
i.e.
[tex]Q_d = Q_s[/tex]
This gives:
[tex]48 -9P = 12 + 6P[/tex]
Collect Like Terms
[tex]-9P - 6P = 12 - 48[/tex]
[tex]-15P = -36[/tex]
Solve for P
[tex]P = \frac{-36}{-15}[/tex]
[tex]P =2.4[/tex]
This is the equilibrium price.
Substitute 2.4 for P in any of the quantity functions to give the equilibrium quantity:
[tex]Q_d = 48 - 9P[/tex]
[tex]Q_d = 48 - 9 * 2.4[/tex]
[tex]Q_d = 26.4[/tex]
Hence, the equilibrium quantity is 26.4

Find the standardized test statistic t for a sample with n = 15, = 10 , s = 0.8, and if Round your answer to three decimal places.
Complete question :
Find the standardized test statistic t for a sample with n = 15, x = 10, s = 0.8, H0: μ = 10.5. Round your answer to three decimal places.
Answer:
−2.420614
Step-by-step explanation:
Given that:
Given that:
n = 10
s = 0.8
X = 15
μ = 15.9
Using the relation :
(x - μ) / (s/√n)
(10 - 10.5) / (0.8/√15)
-0.9 / 0.2065591
= −2.420614
Hence, the standardized test statistic = −2.420614

Thank you and please rate me as brainliest as it will help me to level up
HELPPPPP PLEASE I DONT GET THIS THANKS
Answer:
√10
Step-by-step explanation:
Pythagorean theorem. a^2+b^2=c^2.
In this case 9^2+b^2=√91^2. That equals 81+b^2=91. You isolate b^2, b^2=10. So b=√10.
