Hospital waiting room times are normally distributed with a mean of 38.12 minutes and a standard deviation of 8.63 minutes. What is the shortest wait time that would still be in the worst 5% of wait times? Homework Help: 4VE. Determining values from normal distributions based on probabilities (Links to an external site.) (2:42) 4DC. Using normal distributions and probabilities to determine set values DOCX Group of answer choices 29.49 minutes 52.32 minutes 23.92 minutes 46.75 minutes
Answer:
Step-by-step explanation:
waiting times follow a normal distribution with
Mean, \mu=38.12Mean,μ=38.12
Standard\ deviation,\sigma=8.63Standard deviation,σ=8.63
Longer waiting times are worse than shorter waiting times. Hence the worst 20% of wait times are wait times on the right tail of the distribution. The inferred level of confidence is 0.80.
The z value corresponding to the right tail probability of 0.2 is
Z=0.85Z=0.85
But
Z = \frac{x-\mu}{\sigma}Z=
σ
x−μ
x =Z*\sigma +\mux=Z∗σ+μ
=0.85 * 8.63 +38.12 =45.4555=0.85∗8.63+38.12=45.4555
answer:
the shortest wait time that would still be in the worst 20% of wait times is 45.4555 minutes

Answer:
199.5in^3
Step-by-step explanation:
To do this we first need to find the area of the triangle to do that we can do 3.5*2=7
(since there are two triangles we can do it like this to make it easy)
then we can multiply it like so
7*28.5=199.5

Dividend is equal to :
divisor * quotient - remainder
divisor , quotient
divisor x quotient + remainder
divisor * quotient x remainder
Answer:
divisor × quotient + remainder
Step-by-step explanation:
the dividend is the number thats going to be divided. (for example, 10 crayons divided by 2 people). the formula to find this would be multiplying the divisor by the quotient, and adding the remainder if there is one.
Dividend is equal to:
divisor × quotient - remainderdivisor , quotientdivisor x quotient + remainderdivisor × quotient x remainder✭ Explanation -:To solve this question first we should know the following terms :
[tex] \bull \: \small\sf{ Dividend}[/tex]
A number to be divided by another number.[tex] \bull \: \small\sf{ Divisor}[/tex]
A number by which another number is to be divided.[tex] \bull \: \small\sf{ Quotient}[/tex]
A result obtained by dividing one number by another.The formula for dividend is
[tex] \star \: \small \boxed{\sf{ Dividend = Divisor × Quotient + Remainder }}[/tex]
Hence opition 3) is the correct answer. In a science experiment, Katrina needs to know the mass of a seed pod.
She measures the mass of 8 seed pods as 10.4g.
What is the mass of 1 seed pod?
Answer:
1.30g
Step-by-step explanation:
The mass of 8 seed pods is equal to 10.4g.
10.4g = 8 pods
Total mass / Total pods = Individual pod weight
10.4g / 8 pods = 1.30g per pod
Lets check our work to confirm:
1.30g x 8 pods = 10.4g

Ollie purchased 35 cubic feet of mulch. His landscaper works in cubic meters. Convert 35 cubic feet to cubic meters. Round to the nearest whole number.
Answer:
The nearest number would be 40.
Step-by-step explanation:
(Look below at picture to see my explation))
When rounding you have to round right? So when rounding 35 to the closest number it would be 40. 34 or less would be 30, 35 or more would be 40.
Answer:
The nearest number would be 40.

fencing for $25.50/m. Her family has $165 to spend. What dimensions should Sarah use to build a
garden with the greatest area? Round all answers to 2 decimal places.
Answer:
circle with circumference of 6.47m
Step-by-step explanation:
1. $165/$25.50=6.47058823529m
2. she should use a circle because they have the greatest area, the circle should have a circumference of 6.47m.

Answer:
137°
Step-by-step explanation:
So the question given that triangle ABC is similar to triangle DEF right?
For similar triangles we get the following properties:
-corresponding angles are the same
[∴angle A = angle D, angle B = angle E, angle C = angle F]
-ratio of the corresponding sides of the two triangles are the same(not related to this question)
So, we get angle D = 64°, angle G = 64 + 73 = 137° (ext. ∠ of Δ)
A bus as speed of 20m/s begin to slow at constant acceleration of 8.00m/s2 along a straight line find the average speed for the 5al.s interv
Answer:
-20 m/s.
Step-by-step explanation:
The computation of the average speed is shown below:
Given that
The initial velocity of the bus, u = 20 m/s
Aceleration of the bus, -a = 8 m/s²
time of motion, t = 5 s
Now The final velocity of the bus is
v = u + at
v = 20 + (-8 × 5)
v = 20 - 40
v = -20 m/s.

USE SYSTEMS BY SUBSTITUTION.
X=
Y=
Answer:
X=-2
Y=0
Step-by-step explanation:
X+y=-2 = x=-2-y
3x+4y=-6
3(-2-y)+4y=-6
-6-3y+4y=-6
y=0
x+3(0)=-2
x=-2
Answer:
[tex]\boxed {\boxed {\sf (-2,0)}}[/tex]
Step-by-step explanation:
To solve by substitution we must first isolate 1 variable in an equation.
Let's use the first equation.
[tex]x+3y= -2[/tex]
Subtract 3y from both sides to isolate the variable x.
[tex]x+3y-3y= -2 -3y[/tex]
[tex]x= -2 -3y[/tex]
Now we can substitute the expression (-2-3y) in for x in the second equation.
[tex]3x+4y= -6[/tex]
[tex]3(-2-3y)+4y= -6[/tex]
Distribute the 3. Multiply each term inside the parentheses by 3.
[tex](3*-2)+ (3*-3y)+4y=-6\\-6-9y+4y=-6[/tex]
Combine the like terms on the left side.
[tex]-6-5y= -6[/tex]
Add 6 to both sides to isolate the variable.
[tex]-6+6-5y=-6+6\\-5y=0[/tex]
Divide both sides by -5.
[tex]-5y/-5=0/-5 \\y=0[/tex]
Now we know that y is equal to 0 and can substitute it into the first equation and find x.
[tex]x+3(0)=-2[/tex]
[tex]x+0=-2 \\x= -2[/tex]
x is equal to -2 and y is equal to 0.

Answer and Step-by-step explanation:
4 hours on Monday, so subtract 4 from 16.
We get 12.
So now it says twice as many on Saturday as on Thursday
So two numbers that add up to 12, but one number is twice the other number, would be 4.
4 times 2 is 8, and 4 + 8 is 12. 12 + 4 = 16
8 is the answer.
Kyle works 8 hours on Saturday.
Since 8 is twice the amount of 4, and 8 + 4 + 4 equals 16.
