The time X it takes Hattan to drive to work on a randomly selected day follows a distribution that is approximately Normal with mean 15 minutes and standard deviation 6.5 minutes. Once he parks his car in his reserved space, it takes 5 more minutes for him to walk to his office. Let T = the total time it takes Hattan to reach his office on a randomly selected day, so T = X + 5. Describe the shape, center, and variability of the probability distribution of T.
Answer:
Shape: Approximately Normal
Center: 20 minutes
Variability: 6.5 minutes.
Using statistical concepts, it is found that the distribution is normal, with mean (center) of 20 minutes, and standard deviation of 6.5 minutes.
When a constant is added to a normal variable, the distribution remains normal and the standard deviation remains constant, while the constant is added to the mean.
In this problem, a constant of 5 minutes is added to a normal variable with mean of 15 minutes and standard deviation of 6.5 minutes, hence, the distribution is:
Normal, with mean (center) of 20 minutes, and standard deviation of 6.5 minutes.

what is 3/4÷ 1/8? with a explanation
Answer:
The answer is 6.
Step-by-step explanation:
you have 3/4 divided by 1/8, first you find a common denominator, which is 8. Second you do 3 x 2 and 4 x 2, you should get 6/8 divided by 1/8, and 6 divided by 1 is still 6.
Answer:
6
Step-by-step explanation:
3 /4 × 8 /1 =
3×8/4×1=24/4
3x8 is the numerator 4x1 is the denominator

What is the ratio of the calories Robyn
burned on Wednesday le the celories she
burned on Monday?
Question isn't complete but we make assumptions in order to complete the question and explain
Answer and explanation:
If we are given a table on calories burned by Robyn on weekdays from Monday to Friday and on this table Robyn burnt 500 calories on Monday and burnt 400 calories on Wednesday, then we are required to determine the ratio of calories burnt on Wednesday to calories burnt on Monday:
Calories burnt on Wednesday = 400
Calories burnt on Monday =500
Ratio of calories burnt on Wednesday to calories burnt on Monday =400/500=4/5
Ratio =4:5
Junior has a recipe that uses 1 3/4 cups of brown sugar and 3 1/3 cups of flour to make 18 muffins. He has a total of 10 cups of flour. Junior wants to use all his flour to make as many muffins as possible using this recipe. Exactly how many muffins will Junior make if he uses all 10 cups of flour? Think: How many groups of 3 1/3 cups equals 10 cups total. Don’t forget each batch makes 18 muffins.
Answer:
54 muffins
Step-by-step explanation:
Given that:
Cups of flour used to make recipe = 3 1/3 cups
Total cups of flour = 10 cups
Number of muffins per recipe = 18
Number of recipes that can be made from 10 cups of flour :
Total cups of flour / cups of flour per recipe
10 ÷ 3 1/3
10 ÷ 10/3
10 * 3/10
30 /10
= 3 recipes
Total number of muffins :
Number of muffins per recipe * number of recipe
18 * 3 = 54 muffins

an investor has 200k to invest among 4 possible investments including apple Inc. Each investment must be in units of 10k. Out of 200k, at least 50k must be invested to apple inc. If the whole 200k is invested, how many different investment strategies are possible
Answer:
The four investments are possible.
Step-by-step explanation:
Investor has 200k to invest,
The 4 investment are:
1. Apple inc
2. B inc
3. C inc
4. D inc
Assuming the other three investments are B, C and D.
If 50k is invested in Apple inc, how much is left?
200k -50k = 150k
This remaining 150k can shared equally amongst the other three investments ;
150/ 3 = 50
Therefore each investment will get 50k each.

There are 13 students in one line and 21 students in the other line. If the 5 points
Salome is 2 feet 5 inches tall. How many inches tall is Salome?
Answer:
Salome is 29 inches tall.
Step-by-step explanation:
Each feet has 12 inches.
Salome:
Salome is 2 feet 5 inches tall.
Since each has 12 inches, 2 feet = 2*12 = 24 inches
24 + 5 = 29 inches.
So Salome is 29 inches tall.

A circle has a diameter of
18
m. Find the area of the sector
whose central angle is 135°
Answer:
[tex]\boxed {\boxed {\sf \frac{ 243}{8} \pi , 95.3775, or \ 95.42587686 \ m^2 }}[/tex]
Step-by-step explanation:
When given the central angle in degrees, the formula for sector area is:
[tex]A=\frac{ \theta}{360} * \pi r^2[/tex]
where θ is the central angle and r is the radius.
We are given the diameter, so we must calculate the radius. The radius is half the diameter.
r= d/2The diameter is 18 meters.
r= 18 m/2 r= 9 mNow we know all the variables:
θ=135 r= 9 mSubstitute the values into the formula.
[tex]A=\frac{ 135}{360} * \pi (9)^2[/tex]
Solve the exponent first.
(9)²= 9 m *9 m= 81 m²[tex]A=\frac{ 135}{360} * (81 \ m^2) \pi[/tex]
Solve the fraction.
[tex]A=\frac{ 3}{8} * (81 \ m^2) \pi[/tex]
Multiply the two rational numbers.
[tex]A=\frac{243}{8} \pi \ m^2[/tex]
The answer can be left like this, in terms of pi, or can be multiplied.
Using 3.14 as pi[tex]A=\frac{243}{8} *3.14 \ m^2[/tex]
[tex]A= 95.3775 \ m^2[/tex]
Using the pi button as pi[tex]A= 95.42587685 \ m^2[/tex]
The area is 243/8 π, 95.3775, or 95.42587685 square meters.

Which of the solutions are extraneous?
Answer this pleaseee !!
Answer:
D.
Step-by-step explanation:
m<F = m<B - Corresponding Angles Theorem
m<B + m<A = 180 - Adjacent Angles Theorem
180 - 105 = m<A
75 = m<A; therefore, m<A = 75.
Answer:
D.
Step-by-step explanation:
Because F and C are consecutive angles, they add up to 180°. So 180-105=75. Angle C is 75, which makes B wrong. After finding that C is 75°, then you use the verticle angles theorem to show that angle A is 75°. Hope this helps you.

Which statement best predicts the weather for Denver, Colorado on day 3.
Answer:
Denver should be experiences balmy weather on day 3. Temps vary depending on the month, but overall no storms, and fairly clear weather should be present.
Step-by-step explanation:
A higher pressure system is moving closer to Denver, making for sunnier and calmer weather. It also seems like the nice H should stick for around 2-5 days if the low and high pressure systems continue in what seems to be a slight loop, the low pressure system will probably be moving to the Northeast soon. Overall Denver should be experiencing nice weather, perhaps a bit colder because of the cold front that seems to have sweeped through before Day 1.
