Answer:
$39.36
Step-by-step explanation:
Since its 20% off that means we still have a remaining 80% so first multiply 0.8 to the 82
82x0.8= 65.6
Since there is a additional 40% off multiply by 0.4 to get the discount amount
65.6x0.4= 26.24
Subtract the discount from the price
65.6-26.24= 39.36

3(x-6) is the correct answer to your question :)
Answer:
3x - 6 or 3x -6
Step-by-step explanation:
it is a distrubuve property so u multiply the numbers in the bracket by 3.so 3 time x is 3x.and the other one if it is -2 it is -6 but if its just 2 it is 6.

Given P(A) = 0.56, P(B) = 0.45 and P(B|A) = 0.7, find the value of
P(A and B), rounding to the nearest thousandth, if necessary.
Answer:
P(A and B) = P(AnB)
Step-by-step explanation:
[tex]P( \frac{A}{B} ) = \frac{P(AnB)}{P(B)} \\from \: bayes \: theorem \\ P(AnB) = P(B) \times P( \frac{A}{B}) \\ = 0.45 \times 0.7 \\ = 0.315[/tex]
Answer: 0.392
Step-by-step explanation:
So P(A)xP(B|A)= P(AnB)
Plug in
0.56x0.7=0.392

Which equation is y = (x + 3)2 + (x + 4)2 rewritten in vertex form?
y = 2 (x + seven-halves) squared minus one-fourth
y = 2 (x + seven-halves) squared minus one-half
y = 2(x + 7)2 – 73
y = (x + 7)2 – 24
Answer:
y = 2 (x + seven-halves) squared minus one-fourth [y = [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex] ]
Step-by-step explanation:
We know that,
vertex form is y = a(x-h)² + k
vertex is (h, k)
Now,
Given that the equation is -
y = (x+3)² + (x+4)²
= x² + 3² + 2×3×x + x² + 4² + 2×4×x
= x² + 9 + 6x + x² + 16 + 8x
= 2x² + 14x + 25
= [tex]x^{2} + 7x + \frac{25}{2}[/tex]
= [tex]x^{2} + 7x + \frac{25}{2} + \frac{49}{4} - \frac{49}{4}[/tex]
= [tex](x + \frac{7}{2} )^{2} + \frac{25}{2} - \frac{49}{4}[/tex]
= [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex]
∴ we get
The vertex form is -
y = [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex]
So,
The correct option is - y = 2 (x + seven-halves) squared minus one-fourth (y = [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex] )

Answer:
$9.75
Step-by-step explanation:
Here are two ways of solving this:
Method 1) calculate 35% of original price and subtract from original price
original price: $15
discount rate: 35%
amount of discount: 35% of $15 = 0.35 * $15 = $5.25
final price = original price - amount of discount = $15 - $5.25 = $9.75
Method 2) calculate the percent the discount amount is, and calculate the amount
original price = $15 = 100% of original price
discount rate = 35%
Since the discount rate is 35%, then 100% - 35% = 65%, meaning the sale price is 65% of the original price.
final price = 65% of $15 = 0.65 * $15 = $9.75
Answer: $9.75

Solve the system by substitution.
x=-6y 4x + 10y = 14
Answer:
x = 6
y = -1
Step-by-step explanation:
x = - 6y ----------------------(I)
4x + 10y = 14 ------------------(II)
Substitute x = -6y in equation (II)
4*(-6y) + 10y = 14
-24y + 10y = 14 {Combine like terms}
-14y = 14 {Divide both sides by 1-4}
y = 14/-14
y = -1
Now, substitute y = -1 in equation (I)
x = - 6*(-1)
x = 6

Use the information provided to solve the word problem below. The cost of a school banquet is $65 + $11n, where n is the number of people attending. Which is the cost for 70 people? a. $147 b. $834 c. $835 d. $146 Please select the best answer from the choices provided A B C D
Answer:
$835 (Answer c)
Step-by-step explanation:
Write out the Cost function: C(n) = $65 + ($11/person)n
Then the total cost for 70 people would be C(70) = $65 + ($11/person)(70 people)
C(70) = $65 + $770 = $835 (Answer c)

Answer:
n must be 27
Step-by-step explanation:
Let this number be x. Then -6(n - 12) = -90.
Dividing both sides by -6 yields n - 12 = 15.
Add 12 to both sides.
Then n must be 27.
Check: subtract 12 from 27; this yields 15. Now multiply this result by -6. The result is -90, which was expected.

Tiffany scored 80 on the exam.
Find the Z-score for Tiffany's exam grade. Round to two decimal places.
Answer:
0.85
Step-by-step explanation:
The Z-score for Tiffany's exam grade will be 0.85. The value of Z score for the different distribution is different.
What is the z score?The z-score is a numerical assessment of a value's connection to the mean of a set of values, expressed in terms of standards from the mean, that is used in statistics.
The Z score is found as;
[tex]\rm Z= \frac{x-\mu}{\sigma} \\\\ Z=\frac{80-77}{3.5} \\\\ Z=0.85[/tex]

In a right triangle one angle measure 28° more than the other acute angle. Use equations to solve for the measures of the two unknown angles.
Answer:
One acute angle is 31 degrees and the other acute angle is ( 31+28=) 59 degrees.
Step-by-step explanation:
In the right angled triangle one angle is always equal to 90 degrees.
Suppose <a= 90 degrees
< b= x degrees
< c= x+28 degrees
The sum of all the angles of the triangle are always equal to 180 degrees
therefore
<a+ <b+<c= 90 + x+ x+28 = 180
or
2x= 180- 28- 90
2x=62
x= 31 degrees
One acute angle is 31 degrees and the other acute angle is ( 31+28=) 59 degrees.
An acute angle is an angle which has less than 90 degrees in measurement .
Hence both angles of the right angle triangle are acute angles , 31 and 59 degrees.
