Suppose the board of directors for Cosmic Coffee wants to know the price range for the lowest 40% of drink sales. Find the z-score associated with the upper boundary of of this price range.
Answer:
The z-score associated with the upper boundary of of this price range is -0.25.
Step-by-step explanation:
It is provided that the board of directors for Cosmic Coffee wants to know the price range for the lowest 40% of drink sales.
If X represents the price range of drink sales, then
P (X < x) = 0.40
Consider that X follows a Normal distribution.
To compute the probability of a normally distributed random variable we need to first convert the raw score to the z-scores.
The formula to z-score is:
[tex]z=\frac{X-\mu}{\sigma}[/tex]
Then,
P (X < x) = 0.40
⇒ P (Z < z) = 0.40
The value of z for this probability is:
z = -0.25
*Use a z-table.
Thus, the z-score associated with the upper boundary of of this price range is -0.25.
Answer:
-0.25

Maggie buys 1 1/2 pounds of walnuts pounds of walnuts 8 ounces 8 ounces of pecans of pecans and 3/4 pounds of almonds how much do the nuts weigh in all
Answer:
[tex]2\frac{3}{4}[/tex] pounds
Step-by-step explanation:
Maggie buys 1 1/2 pounds of walnuts, 8 ounces of pecans and 3/4 pounds of almonds.
To find the total weight of nuts that she buys, let us first put all the weights in a single unit, pounds.
She buys 8 ounces of pecans.
1 ounce = 0.0625 pounds
8 ounces = 8 * 0.0625 = 0.5 pounds = 1/2 pounds
Therefore, the total weight of nuts that she buys is:
[tex]1\frac{1}{2} + \frac{1}{2} + \frac{3}{4}\\ \\\frac{3}{2} + \frac{1}{2} + \frac{3}{4} = 2\frac{3}{4}[/tex]
The nuts weight [tex]2\frac{3}{4}[/tex] pounds in all.
Answer:
the answer is 2 3/4 pounds

–6 − 8r = 8 − r
Answer:
1
Step-by-step explanation:
–6 − 8r = 8 − r
− 8r - r = 8 + 6
-9r = 14
r = -14/9
Answer:
r =-2
Step-by-step explanation:
–6 − 8r = 8 − r
Add r to each side
–6 − 8r+r = 8 − r+r
-6 -7r = 8
Add 6 to each side
-6+6 -7r = 8+6
-7r = 14
Divide each side by -7
-7r/-7 = 14/-7
r =-2

Corrected Question
What does [tex]-\dfrac35>-2[/tex] indicate about the position of [tex]-\dfrac35[/tex] and −2 on the number line?
Options
negative 3 over 5 is located on the right of −2
negative 3 over 5 is located on the left of −2
negative 3 over 5 is located on the right of 0 and −2 is located on the left of 0
negative 3 over 5 is located on the left of 0 and −2 is located on the right of 0
Answer:
(A)negative 3 over 5 is located on the right of −2
Step-by-step explanation:
Given the inequality: [tex]-\dfrac35>-2[/tex]
On a number line, numbers are written from the left to the right in ascending order.
Therefore:
Any number y to the right of another number x is greater than x, y>x.Any number a to the left of another number x is less than b, a<b.Negative numbers are to the left of 0.In the given inequality [tex]-\dfrac35>-2[/tex] , both numbers are negative and are therefore to the left of 0.
However, since [tex]-\dfrac35[/tex] is greater than -2, it is located to the right of -2 .
The correct option is A.

Betty turned 71 this year but in three more years she will be twice as old as her daughter. How old is her daughter now
Answer: Betty's daughter is 34 years old now.
Step-by-step explanation:
So Betty is currently 71. In three years, she will be 74. So she will be twice as old as her daughter at the age of 74. To find out how old Betty's daughter is in 3 years, I will divide 74 by 2, which is 37 (74/2). Finally, I will subtract the original 3 years from the 37 years of age of Betty's daughter, and I will get my answer for how old Betty's daughter is, which is 34 years old.

June and the total of 4/6 hour on her math and reading homework which pair of models could show the amount of time in hours she spends on each subject
Answer:
2/3
Step-by-step explanation:
The parks department is installing a
fence along a scenic overlook. The area
to be lenced has 3 sides measuring 4V5
feet. 3 v 5 leet, and 5V5 feet. Find the
total amount of fencing that needs to be
installed.
Answer:
60 square feet.
Step-by-step explanation:
The area to be fenced has two rectangles and one square. We add the areas of the rectangles to that of the square to obtain the total amount of fencing required.
Area of 4 × 5 feet rectangle =(4 × 5) = 20 square feet
Area of 3 × 5 feet rectangle =(3 × 5) = 15 square feet
Area of 5 × 5 feet square =(5)² = 25 square feet
So the total amount of fencing that need to be installed is 20 + 15 + 25 square feet = 60 square feet.

State the slope and y-intercept of the graph of the equation y = 3x + 2
The slope is _________.
The y-intercept is ____________-
the radius of a circle with a circumstance of 28 pie into units
Answer:
The radius is 14
Step-by-step explanation:
The circumference of the circle is 28 pi
C = 2* pi *r where r is the radius
28 pi = 2 pi *r
Divide each side by 2 pi
28 pi/2pi = 2 pi *r/2pi
14 = r

3. WEDNESDAY (5/20): The minimum of the graph of a quadratic function is located at (-1,2). The point (2, 2015
also on the parabola. Which function represents this?
a) f(x) = x² + 2x + 3
b) f(x)= x² - 2x+3
c) f(x) = 2x²+4x+4
d) f(x)= 2x²- 4x+4
Answer:
C.) f(x) = 2x^2 + 4x + 4
Step-by-step explanation:
The equation of the parabola with vertex (h,k) is y=a(−h+x)^2+k.
Thus, the equation of the parabola is y=a(x+1)^2+2.
To find a, use the fact that the parabola passes through the point (2,20): 20=9a+2.
Solving this equation, we get that a=2.
Thus, the equation of the parabola is y=2(x+1)^2+2.
TO STANDARD FORM
= 2*(x^2+2x+1)+2
=(2x^2+4x+2)+2
= 2x^2+4x+2+2
= 2x^2+4x+4

Solve the system of linear equations by elimination.
x + y = 7
5x + 2y = 8
Answer:
(-2, 9)
Step-by-step explanation:
1) Multiply each term of the top equation by two.
2(x) + 2(y) = 2(7)
2x + 2y = 14
2) Use elimination to get rid of the y's
2x + 2y = 14
-(5x + 2y = 8)
Translates to...
2x + 2y = 14
+ (-5x - 2y = -8)
= -3x = 6
3) Solve for x by dividing each side of the equation by -3.
[tex]\frac{-3x}{-3} = \frac{6}{-3}[/tex]
x = -2
4) Plug in x to find the y-value
x + y = 7
-2 + y = 7
-2 + 2 + y = 7 + 2
y = 9
