The Bradenton Post polled 1,356 adults in the city to determine whether they wet their toothbrush before they put toothpaste on it. Of the respondents, 54% said they wet it first. Suppose 68% of all adults actually wet their toothbrush first. What are the mean and standard deviation of the sampling distribution?
Answer:
deviation = -95.50147493 mean = 61
Step-by-step explanation:
54% wet there brushes first
suppose 68% wet there brushes what is the mean
mean: a mean is where you add both numbers together to get a total then divide by how many numbers you added for now we wont need the amount of people we just need the percentages for this
54 + 68 = 122
we added to numbers so well divide by 2
122 divided by 2 or 122/2 is equal to 61
61 is our mean
standard deviation : this is were you take the known average 1356 adults and subtract the mean
1356- 61 = 1295 then divide by 1356 and times by 100
if the number is positive then the mean is higher than expected but luckily its a negative so its -95.50147493

The equations of three lines are given below. Line 1: 6x-4y=6 Line 2: -2y=3x+5 Line 3: y=-2/3x+7 For each pair of lines, determine whether they are parallel, perpendicular, or neither.
Answer:
Line 1 and Line 2: Neither -- slopes are not same (one is negative one is positive)
Line 1 and Line 3: Perpendicular -- Line 3's slope is the negative reciprocal of Line 1's
Line 2 and Line 3: Neither -- different slopes
Step-by-step explanation:
Lines are parallel if they have the same slope but different y-intercept.
Lines are perpendicular if the slopes are negative reciprocals.
The length of a rectangle is 3ft more than twice the width, and the area of the rectangle is 54ft^2. Find the dimensions of the rectangle.
Answer: Let length = 2x + 3
Let width = x
Area = 54 ft2
length × width = Area
x(2x + 3) = 54
2x2 + 3x = 54
2x2 + 3x - 54 = 0
(2x - 9)(x + 6) = 0
x = 9/2 and x = -6
x = 4.5 and x = -6
We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:
width = 4.5 ft
length = 2(4.5) + 3 = 9 + 3 = 12 ft

PLEASE ASAP Find the value of x
Answer: this is in a fraction: X = 16/5, decimal form: x = 3.2, and in a mix number: x = 3 1/5
Step-by-step explanation:
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Write 0.192 and 0.042 as a fraction. Write 189/1000 and 3/1000 as a decimal.
Answer:
0.192 = 24/125
0.042 = 21/500
189/1000 = 0.189
3/1000 = 0.003
As fraction
0.192 =
[tex] \frac{192}{1000} = \frac{24}{125} [/tex]
0.042 =
[tex]\frac{42}{1000} = \frac{21}{500} [/tex]
As decimal
189/1000 = 0.189
3/1000 = 0.003
Alice earned $12 per hour. What equation shows the relationship between her weekly salary (w), hours per week (h), and rate per hour (r).
Two third of a number is greater than one third of the number by 5. The number is ________
Let's assume the number as x
→ ⅔rd of x =( ⅔)x
Now ⅔ of x is greater than ⅓ of 5 .
[tex] \sf{ \implies \: \dfrac{1}{3} \times 5 = \dfrac{5}{3} } [/tex]
[tex]\sf{ \implies \: \dfrac{2}{3} \times x > \dfrac{5}{3} } [/tex]
[tex]\sf{ \implies \: x > \dfrac{5}{3} \times \dfrac{3}{2} }[/tex]
[tex]\sf{ \implies \: x > \dfrac{5}{2} }[/tex]
So number will be greater than 5/2 .

Right triangle XYZ, with vertex Y at (-3, 0), is rotated clockwise 180° about the origin. Which of the following rotations is equivalent to 180° clockwise rotation about the origin? clockwise 360° counterclockwise 180° counterclockwise 360° clockwise 270°
Answer:
the rule for rotation 180 degrees clockwise around the origin is:
(x,y) --------> (-x,-y)
(-3,0) --------> (-(-3),0)
(-3,0) --------> (3,0)
rotation counterclockwise 180 degrees is the same as rotation 180 degrees clock wise:
(x,y) -------->(-x,-y)
Answer:
the answer is counterclockwise 180

The surface area of a cube is 600 cubic centimeters. What is the volume? Answer Choices are on the Image.
Answer:
D. 1,000 cm^3
Step-by-step explanation:
Surface area of a cube is calculated by multiplying the square value of the edge by 6 which is shown as 6 × a^2
6 × a^2 = 600
a^2 = 100
a = 10
The volume of a cube is calculated by multiplying edge with itself three times which is shown as a^3
10^3 = 1000
Answer:
D
Step-by-step explanation:
10×10 on each side of the cube= 100. 6 sides = 600.
10×10×10= 1000
Last month I had 8 guppies. This month I have 20 guppies. What is the percent of increase in guppies from last month to this month?
Answer: 150% increase
Step-by-step explanation:
percent of increase: new/old × 100%-100%
--------------
new/this month: 20 puppies
old/last month: 8 puppies
new/old×100%-100%
=20/8×100%-100%
=2.5×100%-100%
=250% -100%
=150% increase
