Step-by-step explanation:

Antonio has $350 to spend on skis. sales tax is 6%. decide if each description of a price and discount, plus sales tax, represents a pair of skis that antonio can purchase with the money he has. choose yes or no for each description. a. 25% off $450 b. 20% off $385 c. $20 off $360 d. 15% off $360 e. $10 off $340.

The amount of money that Antonio can spend will be:

= $350 - (6% × $350)

= $350 - (0.06 × $350)

= $350 - $21

= $329

a. 25% off $450

= $450 - (25% × $450)

= $450 - (0.25 × $450)

= $450 - $112.50

= $337.50

No

b. 20% off $385

= $385 - (20% × $385)

= $385 - (0.2 × $385)

= $385 - $77

= $308

Yes

c. $20 off $360

= $360 - $20

= $340

No

d. 15% off $360

= $360 - (15% × $360)

= $360 - $54

= $306

Yes

e. $10 off $340

= $340 - $10

= $330

No.

Based on the $329 that Anthony has, he can make purchases on:

b. 20% off $385

d. 15% off $360

Answer:

The answer is "Its results are not consistent with its three designs Yes. Its results show significant differences between both the three designs."

Step-by-step explanation:

Following are the distribution of preference:  

[tex]Design 1 =54 \\\\ Design 2=38 \\\\\ Design 3=28 \\\\[/tex]

[tex]Design \ \ \ \ \ \ \ \ \ \ O_i \\ 1 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 54 \\2 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 38\\3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 28 \\Total \ \ \ \ \ \ \ \ \ \ 120[/tex]

An expected frequency([tex]E_i[/tex]) has 40 Null hypotheses to take n=120.to each design:  

The effects of the three designs are standardized  

Inaccurate.  

Hypothesis Alternative:  

The effects of the three prototypes are not uniform

Degrees Of freedom [tex]=(n-1)=(3-1)=2[/tex]

[tex]H_o, x^2 \ test\ statistic \ \sum_i {\frac{(O_i -E_i)^2}{E_i}} \\[/tex]

[tex]= \frac{(54 -40)^2}{40}+\frac{(38-40)^2}{40} + \frac{(28-40)^2}{40}\\\\=49+0.1+3.6\\\\=8.6[/tex]

Chi-squared distribution critical value at [tex]\alpha = 0.05 (x^2 _{0.052})=5.99[/tex]  

Since [tex]x^2, a[/tex] value [tex]> x^2 -[/tex]table of [tex]\alpha =0.05 =5.99[/tex]is determined.  

So[tex]H_o[/tex] is rejected.

Answer:

12.9x-9

Step-by-step explanation:

First you have to combine the like terms which are 5.3x + 7.6x= 12.9x. Then you just rewrite the equation 12.9x-9. You just leave the 9 by it self beacuse thers no other like terms.

Anwer

12.9x−9 :)

5.3x+−9+7.6x

Combine Like Terms:

Answer: B

Step-by-step explanation:

Answer:

x = 77/5

Step-by-step explanation:

I am going to assume that the equation is 83 - 5x = 6. First, we need to subtract 6 on both sides. So, our equation should look like 77 - 5x = 0

Then, add 5x to both sides. So, the equation should be 77 = 5x. Divide by 5 on both sides to get x = 77/5.

half of 36 kg will be 18 kg

The half of the 36 kg is obtained by dividing the quantity by 2 and it is 18 kg.

The division is a mathematical operation that contains decoupling a quantity or number into equal proportions. It is the inverse operation of multiplication. In division, a number called the dividend is divided by another number called the divisor to get the quotient. When a number is not completely divisible by another number, then dividing the number leaves a single digit that cannot be divided further by that number, thus digit is known as the remainder.

Divide 36 kg by 2,

Half of 36 = [tex]\frac{36}{2} = 18[/tex].

Therefore, half of 36 kg is 18 kg.

Answer:

y=1/4x-2

Step-by-step explanation:

slope intercept form is y=mx+b

your equation right now is in standard form: ax+by=c

equation: x-4y=8

what we want to do is isolate y on one side

subtract x from both sides

-4y=-x+8

divide by 4 on both sides

y=1/4x-2

Hope this helps! :)

Answer:

[tex]y = \frac{1}{4} x - 2[/tex]

Step-by-step explanation:

First thing to do is siolate the y variable. We do this by subtracting x from both sides of the equation in this particular equation.

[tex]x - 4y = 8 \\ - x \: \: \: - x \\ - 4y = - x + 8[/tex]

Now we change the -4y into just y using division. We have to divide boths sides by -4 to do so.

[tex] - 4y = - x + 8 \\ \div ( - 4) \: \: \div ( - 4) \\ y = \frac{1}{4}x - 2[/tex]

There it is in slope intercept form.
