Step-by-step explanation:
Because it is 25% off, x is divided by 25 to get the price.

8. Your meal at a local
restaurant is $12.45. Tax
is 6% and you tip 18%.
What is your final cost?
Answers
Answer:
Around $15.44
Step-by-step explanation:
12.45 + (12.45*0.06) + (12.45*0.18) = 15.438
First we need to find a formula.
(12.45+6%)+18%
6 percent of 12.45 is equal to 0.75, approximately. (0.747)
0.75+12.45=13.2
13.2 plus a tip of 18%
18% of 13.2 is 1.06.
13.20+1.06=14.26
the final cost is 14.26

Tesla Battery Recharge Time.The electric vehicle manufacturing company Tesla estimates that a driver who commutes 50 miles per day in a Model S will require a nightly charge time of around 1 hour and 45 minutes (105 minutes) to recharge the vehicle’s battery (Tesla company website). Assume that the actual recharging time required is uniformly distributed between 90 and 120 minutes.
a. Give a mathematical expression for the probability density function of battery recharging time for this scenario.
b. What is the probability that the recharge time will be less than 110 minutes?
c. What is the probability that the recharge time required is at least 100 minutes?
d. What is the probability that the recharge time required is between 95 and 110 minutes?
Answers
Answer:
a.) f(x) = [tex]\frac{1}{30}[/tex] where 90 < x < 120
b.) [tex]\frac{2}{3}[/tex]
c.) [tex]\frac{2}{3}[/tex]
d.) [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Let
X be a uniform random variable that denotes the actual charging time of battery.
Given that, the actual recharging time required is uniformly distributed between 90 and 120 minutes.
⇒X ≈ ∪ ( 90, 120 )
a.)
Probability density function , f (x) = [tex]\frac{1}{120 - 90} = \frac{1}{30}[/tex] where 90 < x < 120
b.)
P(x < 110) = [tex]\int\limits^{110}_{90} {\frac{1}{30} } \, dx[/tex]
= [tex]\frac{1}{30}[x]\limits^{110}_{90} = \frac{1}{30} [ 110 - 90 ] = \frac{1}{30} [ 20] = \frac{2}{3}[/tex]
c.)
P(x > 100 ) = [tex]\int\limits^{120}_{100} {\frac{1}{30} } \, dx[/tex]
= [tex]\frac{1}{30}[x]\limits^{120}_{100} = \frac{1}{30} [ 120 - 100 ] = \frac{1}{30} [ 20] = \frac{2}{3}[/tex]
d.)
P(95 < x< 110) = [tex]\int\limits^{110}_{95} {\frac{1}{30} } \, dx[/tex]
= [tex]\frac{1}{30}[x]\limits^{110}_{95} = \frac{1}{30} [ 110 - 95 ] = \frac{1}{30} [ 15] = \frac{1}{2}[/tex]

1. 5 + y = 7.
2. 3.8 = a + 2.5
5. + p = 9 1/3
Answers
Answer:
1. 5 + y = 7
⇒ y = 7 - 5
⇒y = 5
2. 3.8 = a + 2.5
⇒ a = 2.5 - 3.8
⇒ a = -1.3
3. 5 + p = 9 1/3
⇒ p = 9 1/3 - 5
⇒ p = 28/3 - 5
⇒ p = 28/3 - 15/3
⇒ p = 13/3
⇒ p = 4 1/3
2.A=1.3
5.p=28/3

Now find the measure of ∠YOZ. Which angle relationship did you use?
Answers
The angular measure of ∠YOZ is : 60° and the angular relationship used is vertically opposite angles(VOA).
How are angles formed?Angles are formed when two lines meet. this could be a direct intersection or an intersection between two parallel lines and a transversal.
Angles can be acute, obtuse, or reflex.
Analysis:
Given data:
∠VOX = 90°
∠WOX = 30°
∠WOX + ∠VOW = ∠VOX
30° + ∠VOW = 90°( the two angles are complementary that is they sum up to 90°)
∠VOW = 90 - 30 = 60°
∠VOW = ∠YOZ ( vertically opposite angles are equal)
∠YOZ = 60°.
in conclusion, the angular measure of ∠YOZ = 60° and the angular relationship used is vertically opposite angles.

If 5 of these phones are randomly selected from the factory, then there is about a 95% probability that the sample mean will fall in which interval?
Find the z-table here.
7.5–56.5 hours
21.0–43.0 hours
27.1–36.9 hours
29.8–34.2 hours
31.0–33.0 hours
Answers
Answer:
29.8–34.2 hours
Step-by-step explanation:
Empirical Rule:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Population:
Mean of 32, standard deviation of 2.5.
Sample:
Sample of 5, so [tex]n = 5, s = \frac{2.5}{\sqrt{5}} = 1.1[/tex]
There is about a 95% probability that the sample mean will fall in which interval?
Within 2 standard deviations of the mean. So
32 - 2*1.1 = 32 - 2.2 = 29.8
32 + 2*1.1 = 32 + 2.2 = 34.2 hours
A small book publisher knows that 20 books weigh 37 lbs. How much do 34 books weigh
Answers
Answer:
62.9 lbs
Step-by-step explanation:
20 34
37 x
20x = 1258
x = 62.9
Answer:
[tex]\boxed {\boxed {\sf 62.9 \ pounds}}[/tex]
Step-by-step explanation:
Let's create a proportion using this setup:
[tex]\frac{books}{weight}=\frac{books}{weight}[/tex]
We know that 20 books weight 37 pounds. We don't what 34 books weigh, so the weight is x pounds.
[tex]\frac{20 \ books}{37 \ pounds}=\frac{34 \ books}{x \ pounds}[/tex]
[tex]\frac{20}{37}=\frac{34}{x}[/tex]
Cross multiply. Multiply the first numerator by the second denominator. Then, the first denominator and second numerator.
[tex]20*x=37*34\\20x=1258[/tex]
Since we are solving for x, we have to isolate the variable. It is being multiplied and the inverse of multiplication is division. Divide both sides by 20.
[tex]20x/20=1258/20 \\x= 1258/20 \\x=62.9[/tex]
34 books weigh 62.9 pounds.

At this rate, how many days did it take for all 60 gallons of water to leak out of the barrel?
20 days
12 days
100 days
36 days
Answers
Answer:
36 Days!
Step-by-step explanation:
So A barrel contained 60 gallons of water. Water leaked out of the barrel at a rate of 5 gallons every 3 days. The question is “At this rate, how many days did it take for all 60 gallons of water to leak out of the barrel”? So What I did to find this out is multiplyed 3 by 12 to get 36 days. But When I was doing that I was also paying attention to that 5 gallons of water leak out of the barrel in 3 days, that’s why I multiplyed by 3.
If this doesn’t make sense to you I could explain it better if you need more explanation.
Hope This Helps!
