In a certain region, there is a 0.1 probability that any checked passerine bird's nest will
contain a cuckoo egg. If three passerine nests are checked, what is the probability that
at least two of them contain a cuckoo egg?
Answer:
Probability of at least two cuckoo eggs is 0.738.
Step-by-step explanation:
probability of cuckoo egg = 0.1
probability of not a cuckoo egg = 1 - 0.1 = 0.9
Probability of at least two cuckoo eggs is
= Probability of two cuckoo eggs x probability of 1 not cuckoo egg +
probability of three cuckoo eggs
= 0.1 x 0.1 x 0.9 + 0.9 x 0.9 x 0.9
= 0.009 + 0.729
= 0.738
The Howards bought a $224,000 townhome. They made a down payment of $45,000 and took out a mortgage for the rest. Over the course of 30 years they
made monthly payments of $1073.21 on their mortgage until it was paid off.
th
total amount they ended un naying for the townhome
1 year = 12 months.
30 years x 12 months per year = 360 total months
Multiply total months by monthly payment:
360 months x 1,073.21 per month = $386,355.60 total monthly payments for 30 years.
Now add the down payment to the total monthly amount:
$386,355.60 + $45,000 = $431,355.60
Total amount paid: $431,355.60
One side of a triangle is 3 times longer than the shortest side and the third side is 4 centimeters longer than the shortest side. The perimeter of the triangle is 64.
How long is the shortest side of the triangle?
Answer:
First side is: 12cm
Second side is: 36cm
Third side is: 16cm
Step-by-step explanation:
Let x represent the shorter side
Then 3x represents the second side, and
x + 4 represents the third side.
Perimeter of three sides:
P = x + 3x + (x + 4)
Perimeter is 64, so
64 = x + 3x + (x + 4)
64 = 5x + 4
60 = 5x
12 = x
First side is x: 12cm
Second side is 3x: 3(12) = 36cm
Third side is x + 4: 12 + 4 = 16cm
Can someone please help me?
Answer:
A
Step-by-step explanation:
to find the inverse, there are two steps
1-interchange x and y
2-solve for y
so y=x+1/x
interchange to get x=y+1/y
and solving for y we multiply both sides by y to get xy=y+1
subtract both sides by y yielding xy-y=1
factor out y to get y(x-1)=1
then divide to get y=1/x-1

Solve for the value of v
Answer:
v = 9 because it is what would make a great answer
Step-by-step explanation:
the angles are supplementary, meaning it sums up to 180 degrees
so to find v, you have to find the total angle of v.
180- 105 equals 8v+3, or 75 equals 8v+3
subtract 75 with 3 leaving 72 equals 8v
v would equal 9
What is the equation of the line in slope-intercept form?
Answer:
2) y=-3x+36
Step-by-step explanation:
Hi there!
We're given a graph and we want to find the equation of the line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
We'll need two points, so pick any two from the graph
For example, let's do (0,36) and (12,0)
first let's find the slope
The formula for the slope calculated from two points is (y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are points
we'll be using (0,36) and (12,0)
let's label the points to avoid any confusion
x1=0
y1=36
x2=12
y2=0
Now substitute into the formula:
m=(y2-y1)/(x2-x1)
m=(0-36)/(12-0)
m=-36/12
m=-3
so the slope is -3
here's the equation so far:
y=-3x+b
we need to find b
The equation of the line will pass through both (0,36) and (12,0) so we can use either one of them to solve for b
let's take (12,0) for example
substitute 12 as x and 0 as y
0=-3(12)+b
multiply
0=-36+b
add 36 to both sides to isolate b
36=b
now substitute 36 as b into the equation
y=-3x+36
There's the equation of the line, so the answer is option 2
Hope this helps!

What is the image point of (1,-7) after the transformation T-3,-1 degrees R180 degrees?
Answer:
first hust rotate 180 and next reflect it over x axis.
the given point (-7,3) id in second quadrant but after rotation it will be in fourth quadrant.
afterwards you have to refect that point over x-axis which gives you the image of the points on first quadrant ie. (7,1).

What is the solution for
X+2y=9 2x+4y=20
Answer:
No solution
Step-by-step explanation:
x + 2y = 9
x = - 2y + 9
2x + 4y = 20
2(-2y + 9) + 4y = 20
-4y + 18 + 4y = 20
-4y + 4y = 20 - 18
0 = 2
( No solution)
In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 80° more than the measure of the second angle. Use the fact that the sum of the measures of the three angles of a triangle is 180° to find the measure of each angle. what is the measure of the first angle?
Answer:
The measure of the first angle is 50°.
Step-by-step explanation:
Let the three angles be a, b, and c.
The measure of the first angle is twice the measure of the second angle. In other words:
[tex]a=2b[/tex]
The measure of the third angle is 80° more than the measure of the second angle. In other words:
[tex]c=b+80[/tex]
And since the interior angles of a triangle must equal 180°:
[tex]a+b+c=180[/tex]
Substitute a and c:
[tex](2b)+b+(b+80)=180[/tex]
Combine like terms:
[tex]4b+80=180[/tex]
Subtract 80 from both sides:
[tex]4b=100[/tex]
And divide both sides by four:
[tex]b=25^\circ[/tex]
So, the measure of the second angle is 25°.
Since the measure of the first is twice the second, the measure of the first angle is 50°.
(And since the measure of the third is 80° than the second, the measure of the third angle is 105°.)
Researchers at a medical school conducted a study to test the effectiveness of a new drug for lowering cholesterol. The 52 subjects who volunteered for the study were each given a randomly generated number. Subjects with an odd number were given the new drug, while those with an even number were given a placebo. Cholesterol levels before and after the treatment were measured for each subject, and the differences were computed.
This study is an example of ______________ study. The difference in cholesterol level is _____________ the variable. The treatment with drug or placebo is the ____________ variable.
Answer:
1. An Experimental
2. Dependent
3. Independent
Step-by-step explanation:
Considering the description of how the research was carried out, it can be concluded that This study is an example of AN EXPERIMENTAL study. This because the researcher is trying to study the effectiveness of a new drug for lowering cholesterol
The difference in cholesterol level is the DEPENDENT variable. This is because the difference in cholesterol level is what the researcher wants to determine.
The treatment with a drug or placebo is the INDEPENDENT variable. This is because this is what the researcher manipulates to determine the difference in cholesterol level which is the dependent variable in this experimental study.

The vertices of a triangle are as follows: (4,) (6,7) and (8,0) If you dilate the triangle by a scale factor of 3, what are the vertices of the new triangle
1. (12,12) (6,7) (24,3)
2. (4,12) (6,21) (8,0)
3. (12,4) (18,7) (24,0)
4. (12,12) (18,21) (24,0)
Answer:
(12, 12), (18, 21), (24, 0)
Step-by-step explanation:
To dilate a figure, you multiple each of the numbers in its coordinates by the scale factor.
The vertices of the new triangle is:
4. (12,12) (18,21) (24,0)
What are the vertices of the new triangle?We have:
The vertices of a triangle: (4, 4) (6,7) and (8,0)
We dilate the triangle by a scale factor of 3
To find the vertices of the new triangle after a dilation of 3, multiply the old vertices by 3. That is:
3 * (4, 4) => (12, 12)
3 * (6, 7) => (18, 21)
3 * (8,0) => (24, 0)
Therefore, the vertices of the new triangle is (12,12) (18,21) (24,0)

what is the largest number in the form x987yz that is divisible by 12?
Answer:
998796
Step-by-step explanation:
For a number to be divisible by 12. it must be divisible by 3 and 4
Since we need the largest 6 digit number, we will take x = 9
So the number is 9987yz
Again since we need the largest number we will consider the largest 2 digit number multiple of 4 and 3.
Largest 2 digit number divisible by 4 is 96, which is also divisible by 3.
So, yz = 96
Therefore , the largest number in the form will be : 998796
Answer:
The largest number is 998796
------------------------------------------------------
The largest digit you could use is 9 so, our number would be, 998799,
but the thing is that it's not divisible by 12.
The next largest would be 8. (998798) Not divisible.
7, so our number would be, 998797. Not divisible.
6, 998796. 998796/12= 83233, which means that it is divisble, so, the largest number in the form x987yz that is divisble by 12 is 998796
Please correct me if I'm wrong.
