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

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 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

Step-by-step explanation:
The question says find the number eight times of a certain two digit number exceeding the number 19.The tens digit than the units digit . So,you have to multiply eight to a two digit number exceeding 19 so you find a number exceeding 19 which would have to be able to to multiply by eight to exceed the number 19
find the number eight times of a two digit number higher than the number nineteen. The tens digit than the units digit .you have to multiply 8 to a 2 digit number exceeding nineteen so you find a number exceeding ninteen which would have to be able to to times by 8 to go higher than the number nineteen
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

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

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 .
