PLS HELP!!!! I KEEP GETTING SCAM LINKS!!!! AND I NEED TO FINISH THIS PROBLEM FOR A TEST... A TV that usually sells for $172.09 is on sale for 25% off. If sales tax on the TV is 6%, what is the price of the TV, including tax?
Answers
first, you start out with 172.09. you multiply 6% by 172.09.
now that you have 10.3254, round it to 10.33.
this is the amount of sales tax that the tv has.
you’re gonna add that 10.33 to the 172.09, you’re gonna get 182.42.
now you’re left with 182.42 and 25%. you’re gonna multiply that 25% by 182.42. you’re gonna get 45.61.
since the tv is 25% off, you’re gonna subtract 45.61 from 182.42.
you’re gonna get 136.81, and that is your answer.
hopefully this helped!!

Mr. Zhāng received a shipment that
arrived in a cardboard box in the shape of a
rectangular prism. The volume of the box
was 110 cubic feet. The area of the base of
the box was 20 square feet. What was the
height of the cardboard box?
Answers
Volume = l•w•h
Length times the width gives you the area of the base.
Volume = b•h
And if you plug it in:
110 = 20h Reduce both sides by 20
5.5 = h

Step-by-step explanation:
A grading scale is set up for 1000 students' test scores. It assumes the
scores are normally distributed with a mean score of 75 and a standard
deviation of 15.
How many students will score between 48 and 75?
hint: recall how to get the standard deviation. What does that mean in
this context? How could you use that to understand how many test
scores could be in one standard deviation?
464
Answers
Answer:
464 students will score between 48 and 75. Using the z-distribution, we measure how many standard deviations each score is from the mean, then find the p-value associated with each score to find the proportion, and from the proportion, we find how many out of 1000.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
It assumes the scores are normally distributed with a mean score of 75 and a standard deviation of 15.
This means that [tex]\mu = 75, \sigma = 15[/tex]
How many students will score between 48 and 75?
First we find the proportion, which is the pvalue of Z when X = 75 subtracted by the pvalue of Z when X = 48. So
X = 75
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{75 - 75}{15}[/tex]
[tex]Z = 0[/tex]
[tex]Z = 0[/tex] has a p-value of 0.5
X = 48
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{48 - 75}{15}[/tex]
[tex]Z = -1.8[/tex]
[tex]Z = -1.8[/tex] has a p-value of 0.0359
1 - 0.0359 = 0.4641
Out of 1000:
0.4641*1000 = 464
464 students will score between 48 and 75. Using the z-distribution, we measure how many standard deviations each score is from the mean, then find the p-value associated with each score to find the proportion, and from the proportion, we find how many out of 1000.

Solve using the Quadratic Equation.
5X^2 – 3X – 8=0
Answers
Answer:
1 (give brainliest plss)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 5 • -8 = -40
Step-2 : Find two factors of -40 whose sum equals the coefficient of the middle term, which is -3 .
-40 + 1 = -39
-20 + 2 = -18
-10 + 4 = -6
-8 + 5 = -3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and 5
5x2 - 8x + 5x - 8
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (5x-8)
Add up the last 2 terms, pulling out common factors :
1 • (5x-8)
Step-5 : Add up the four terms of step 4 :
(x+1) • (5x-8)
Which is the desired factorization

Actually Welcome to the concept of Quadratic Equations.
Degree of a equation represents the highest power of the varible in the equation, For quadratic equation the degree is 2.
Leading Coefficient are the constant numbers that are significantly multiplied with the variables in the equation.
==> 5x^2 - 3x - 8 = 0
==> 5x^2 -8x +5x -8=0
==> x(5x-8) +1(5x-8)=0
==> (5x-8)(x+1) = 0
