Answers
Answer:
no.
Step-by-step explanation:
0.000061 is a decimal, and the number to the left of the decimal would be a whole number, which is 0. this means the number is less than one.. while 610,000 is a number jn the thousands, making it greater.
Answer:
No
Step-by-step explanation: 610,000 is greater than 0.000061 because 0.000061 is a decimal in the 100,000ths place.

The grade seven students are showing a movie in their school auditorium to raise money for the end of year field trip. Goal is to raise at least $500. Each ticket sales for $16. So far they have sold 20 tickets. Which inequality graph correctly shows how many more tickets they need to sell to reach their goal.
Answers
Answer:
The answer is A because it needs to be a filled dot to represent the information correctly. 16 x 20 is 320 so they need 180 more to have at least 500 dollars which is 11.25 tickets but you cant have a fourth of a ticket so you need atleast 12 tickets sold.
One hundred sixty people who suffer from painful diabetic neuropathy have volunteered to participate in a study. Eighty are selected at random and are given the drug gabapentin, which, although originally intended to prevent epileptic seizures, has properties that may make it useful to alleviate neuropathy. The remaining participants are given a placebo. A neurologist evaluates the symptoms of all volunteers after two months to determine if there has been substantial improvement in the severity of the symptoms.
Does the use of volunteers make this study invalid?
a. yes, because of volunteer bias no, because blocking was used.
b. yes, because there is no way to determine the effect of gabapentin on people that do not have symptoms of neuropathy.
c. no, because the subjects are randomly assigned to treatment groups.
Answers
Answer:
C. No, because the subjects are randomly assigned to treatment groups
Step-by-step explanation:
We are told that 80 people are selected at random and are given the drug gabapentin.
Also that the remaining people are given the placebo.
This means that they are randomly assigned treatment groups and so it is a completely randomized block design and as such the use of volunteers doesn't make it invalid.

Find the probability of drawing a 10 from a standard deck
of 52 cards,
Answers
Answer:
4/52 or 1/13 (simplified)
Step-by-step explanation:
There are 4 "10's" in a pack.
This means you have the chance to pick 4 10's.
So out of 52 cards, you can get 4.
4/52 -> Which can be simplified to 1/13.
This is the probability of getting a 10 (once) in a standard deck of cards.
The probability of drawing a 10 from a standard deck of 52 cards is 1/13.
Number of 10's in a standard deck of 52 cards =4
Total cards =52
What is probability?Probability is the measurement of the possibilities of events.
P(event) =Favorable outcomes/ Total possible outcomes
Here, Favorable outcomes =4
Total possible outcomes =52
P(10) =4/52
P(10) =1/13
So, the probability of drawing a 10 from a standard deck of 52 cards =1/13
Thus, the probability of drawing a 10 from a standard deck of 52 cards is 1/13

Answer:
y = -4/3x +23/2
Step-by-step explanation:
The tangent of interest is perpendicular to the radius at the given point on the circle. To find the perpendicular, it helps to know the slope of the radius segment. To find that, we need the center of the circle.
The center of the circle can be found by completing the square for each variable.
(x^2 -2x) +(y^2 +4y) = 20
(x^2 -2x +1) +(y^2 +4y +4) = 20 +1 +4
(x -1)^2 +(y +2)^2 = 25
Comparing this equation to the standard form equation for a circle, we can find the center.
(x -h)^2 +(y -k)^2 = r^2 . . . . . . . circle of radius r centered at (h, k)
The center of circle P is (1, -2).
__
The slope m' of the line segment between (1, -2) and (5, 1) is given by ...
m' = (y2 -y1)/(x2 -x1)
m' = (1 -(-2))/(5 -1) = 3/4
The slope m of the perpendicular line is the opposite reciprocal of this, so is ...
m = -1/m' = -1/(3/4) = -4/3
The y-intercept of the desired line can be found from ...
b = y -mx . . . . . . . for m=-4/3 and (x, y) = (5, 1)
b = 1 -(-4/3)(5) = 23/3
Then the equation of tangent line AB is ...
y = mx +b
y = -4/3x +23/3

Answer:
y = 9√2
Step-by-step explanation:
By applying Pythagoras theorem in the given right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
y² = 9² + x²
By the property of isosceles triangle,
Two angles of the right triangle are equal in measure, opposite sides of these equal angles will be equal in measure.
Therefore, x = 9
y² = 9² + 9²
y² = 81 + 81
y² = 162
y = √162
y = 9√2

Write an equation of the line that passes through the point (-2, 5) and is parallel to the line 2x − 3y = 12.
Answers
Answer:
y = (2/3)x + 19/3
Let me know if there are any parts of the process you do not understand.
Step-by-step explanation:
First you need to know what slope is, if you do not let me know and I can explain it in depth.
Now, you can determine if a line is parallel or perpendicular by its slope. parallel has the same slope and perpendicular has the negative reciporical, which basically means negative 1 divided by the slope.
So if you slope was 3 perpendicular would be -1/3. if the slope is a fraction you can just flip the fraction and make it negative. so if the slope is -2/3 a perpendicular slope would be 3/2, making a negative number negative makes it positive.
Now you start with 2x - 3y = 12. To find the slope I like putting it in slope intercept form. basically somethign that looks liek y = mx + b. to do that just use algebra on what you have to get y by itself. here is how I would do that.
2x - 3y = 12 first subtract 2x from both sides
-3y = 12 - 2x Now divide both sides by -3
y = 12/-3 - (2x)/3 Now simplify
y = -4 + 2/3 x Now rarrange to make it look like I said, basically you want the x first.
y = 2/3 x - 4
There, so the slope is 2/3. A parallel line will have the same slope.
To make the equation of a line you want one point and the slope. Well we have that, the point is (-2,5) and the slope is 2/3.
To find a line you set up the point slope form. that is y - y1 = m(x - x1) where m is the slope and x1 and y1 are the coordinates of the point you need. I will plug all that in.
y - y1 = m(x - x1)
y - 5 = (2/3)(x - (-2)) Now solve
y - 5 = (2/3)x + 4/3
y = (2/3)x + 19/3
So that is the equation of a line parallel to 2x - 3y = 12 that passes through (-2, 5)

In order to find the value of x in this quadratic equation we first need to make the equation equal 0 by getting rid of the 140. We do this by subtracting 140 on each side.
3x² - 7 = 140
3x² - 147 = 0
Now we solve as a regular quadratic formula
