Step-by-step explanation:
Julie manages a franchise restaurant and is analyzing the tips left at her location. From corporate informational material, she knows the overall
population mean is $6.85 with a standard deviation of $1.25. Julie has a sample of 180 tips for her franchise. By the central limit theorem, which
interval can Julie be 95% certain that the sample mean will fall within?
OA. $6.76 and $6.94
O B. $6.57 and $7.13
OC. $6.66 and $7.04
OD. $6.83 and $6.87
Answer:
$6.66 and $7.04
Step-by-step explanation:
I got it right
The $6.76 and $6.94 is the interval Julie can be 95% certain that the sample means will fall within option (A) is correct.
What is the standard deviation?It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
[tex]\rm \sigma = \sqrt{\dfrac{ \sum (x_i-X)}{n}[/tex]
σ is the standard deviation
xi is each value from the data set
X is the mean of the data set
n is the number of observations in the data set.
From the central limit theorem:
σ(x) = σ/√n
The standard deviation σ = $1.25
The sample n = 180
σ(x) = 1.25/√180
σ(x) = 1.25/√1801
σ(x) = 0.0931
The lower limit = 6.85 - 0.0931 = 6.756 = 6.76
The upper limit = 6.85 - 0.0931 = 6.943 = 6.94
Thus, the $6.76 and $6.94 is the interval Julie can be 95% certain that the sample means will fall within option (A) is correct.

Answer:
1) are equal (congruent), are opposite from each other
2) (11y-36)= 63.
3) Add 36 to both sides.
11y = 99. Divide both sides by 11.
Y = 9

At a sale this week, a suit is being sold for $217. This is a 38% discount from the original price. What is the original price?
Answer:
List price (original price) = $350

Step-by-step explanation:
The list price is the sale price ($217) divided by the difference of 1 minus the result of the discount (38%) divided by 100.
What is it’s equation in point slope form?
Answer:
y = -2x + 28
Step-by-step explanation:
Slope intercept form is-
y = mx + b
y = y coordinate
m = slope, the rise/run
x = x coordinate
b = the y-intercept, the place the line crosses the y-axis.
Now, fill in the formula with the proper information.
y = -2x + b You can use the point (10, 8) for the x and y coordinates to find b
8 = -2(10) + b Now solve for b
8 = -20 + b
+20 +20
28 = b Now substitute 28 in for b
y = -2x + 28
Answer:
y-8=-2(x-10)
Step-by-step explanation:
y-y1=m(x-x1)
y-8=-2(x-10)
What is an angle call measure between 90° and 180°
ILL MARK BRAINLYEST
Which statement is true. Supplementary angles:
Group of answer choices
are congruent
add up to 180 degrees
are two angles inside a triangle
add up to 90 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees
Complementary angles add up to 90 degrees
It is just a rule that is important to geometry
I hope that helps :)
Answer:
Add up to 180 degrees
Step-by-step explanation:
Supplementary angles can be two separate angles and the acute angles of a right triangle are complementary which make option 3 false. They are not always congruent and do not add up to 90 degree in total. Making option 1 and 4 false as well.
A bear loves visiting his friend, the piglet. The distance between their houses is 300m , and the bear always walks from his house to the piglet's house in exactly the same amount of time. But today, the bear stops at a beehive after walking —1 of the 4 distance. He eats honey for 2.5 minutes and then continues to the piglet's house at a speed 15 m/min faster than usual. The total journey to the piglet's house takes the exact same amount of time as it usually does, when the bear does not stop for honey. How long does the journey take?
Answer:
10mins
Step-by-step explanation:
you can draw a rtd chart for this problem
rate (m/min)| time (mins) | distance (m )
regular: (300/x) | x | 300m
fist 1/4 : (300/x) | 75: (300/x) | 75m
last 3/4: | (300/x)+15 | 225:(300/x + 15) | 225m
then, make an equation for the times:
x= (75: (300/x)) + (225: ( (300/x)+15) + 2.5 = x
// get the 2.5 mins from the stop for honey, and we know that regular speed is equal to the one with a stop
solve equation to get x=-20/3 , x=10, because speed is positive, x=10 is the most reasonable answer
