A couple plans to have 3 children. Assuming the probability of having either a boy or a girl is 50%, what is the probability they will have at least 1 girl?
Group of answer choices
0.875
0.125
0.375
0.75
Answer:
0.375
Step-by-step explanation:
The probability of having at least one girl out of 3 children can be calculated as;
P(1 girl, 2 boys) or P(2 girls, 1 boy) or P(3 girls)
Since the P(b) = P(g) = 1/2
Then the probability at any point in time is 1/2 * 1/2 * 1/2 = 1/8
So we have ;
1/8 + 1/8 + 1/8 = 3/8 = 0.375

I need help, please and thank you. I know that you have to multiply the diameter by 2 to find the radius, but with the 9 pi, it makes me unsure if I'm doing this correctly.
Answer:
r=6
Step-by-step explanation:
The area of a circle is given by πr². Note that this uses the radius, not the diameter.
Now, one quarter of this area (ABC) is given to be 9π.
So apparently:
[tex]\frac14 \pi r^2 = 9\pi[/tex]
If you solve this:
[tex]\frac14 r^2 = 9[/tex] (divide both sides by π)
[tex]r^2 = 9\cdot4[/tex] (multiply both sides by 4)
so
r = √36 = 6
so the radius is 6.

Answer:
x = 45°
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
since the whole angle is a right angle, we know its worth 90 degrees. since the line separates the 90 into two, with one part being 45, we can take 45 away from 90, and get our answer. 90-45=45. so the value of x=45
What is the slope of the line through (3, 2) and (-3,4)?
Answer:
Choice A. -3
Step-by-step explanation:
Using the x1-x2/ y1-y2 u fill in. So it would be 3-(-3) (x-axis) and 2-4 (y-axis).
So when u do both of those you are left with 6/-2.
When u simplify 6/-2 you get -3.
Answer:
slope is -1/3
Step-by-step explanation:
slope is read rise over run so the line, in this case, fell down 1 and ran 3. Falling means negative so the slope is negative 1 over 3. To easily determine a negative slope, see if the line is moving from top left to bottom right. If so, then it's negative. The other way around is a positive slope.

Which product is equivalent to -7 × 2/5?
Answer:
-2.8 or -14/5
Step-by-step explanation:
All you have to do is put the -7 over 1 and multiply across. So it'd look like:
-7/1 x 2/5 which works out across as -14/5 or you can convert it to a decimal to be -2.8. Hope this helps! :)

Describe the transformation
Answer:
The function is translated 3 units up from its original position.
Step-by-step explanation:
If you look at the equations, nothing is changed besides the + 1 turning into a + 4. What does that mean? Well, if we find the difference between the 4 and the 1 by subtracting, that leaves us with 3. Since the number is positive, this indicates an upward vertical shift.

Michael’s employer just switched to a new payroll system. He wants to make sure that his net pay has been computed correctly. His gross pay per pay period is $587.34. He has the following deductions: Social Security tax (6.2%), Medicare tax (1.45%), federal withholding tax $164.45, state withholding tax $76.34, retirement insurance contribution $50.00, disability insurance fee $8.00, medical insurance fee $23.00, and dental insurance fee $8.00. What should his net pay be for this pay period? Net pay = gross pay – deductions.
Answer:
Step-by-step explanation:
$587.34 x 6.2% = $36.42
$587.34 x 1.45% = $8.52
$36.42 + $8.53 + $164.45 + $76.34 + $50 + $8 + $23 + $8 = $374.73
$587.34 - $374.73 = $212.61
Michael's net pay for this pay period should be $212.63.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let's calculate Michael's total deductions first:
Social Security tax = 6.2% of $587.34 = $36.40
Medicare tax = 1.45% of $587.34 = $8.52
Federal withholding tax = $164.45
State withholding tax = $76.34
Retirement insurance contribution = $50.00
Disability insurance fee = $8.00
Medical insurance fee = $23.00
Dental insurance fee = $8.00
Total deductions.
= $36.40 + $8.52 + $164.45 + $76.34 + $50.00 + $8.00 + $23.00 + $8.00
Total deductions = $374.71
Now we can calculate Michael's net pay:
Net pay = Gross pay - Total deductions
Net pay = $587.34 - $374.71
Net pay = $212.63
Therefore,
Michael's net pay for this pay period should be $212.63.

The expected values of two television sets are predicted as follows.
The function below models the expected value in dollars, of television A after 3 years.
f(x) = 100(-2+4)
The expected value, in dollars, of television B is initially $360 and decreases by $90 each year. Let g(x) represent the
expected value of television B after 3 years.
How does the graph of g(x) compare to the graph of f(x)?
The graph of g(x) has the lesser y-intercept.
The graph of g(x) has the greater 2-intercept.
The graph of g(x) has the greater y -intercept.
o The graph of g(x) has the lesser x-intercept.
Answer:
A. The graph of g (x) has the lesser y -intercept
Step-by-step explanation:
I took the test
For f(x) the y-intercept is given by, c = 400 and for g(x) the y-intercept is given by, c' = 360. The correct option is a) and this can be determined by using the slope-intercept form of the line.
Given :
The function [f(x) = 100(-x + 4)] models the expected value in dollars, of television A after 3 years.The expected value, in dollars, of television B, is initially $360 and decreases by $90 each year.First, determine the function g(x) in order to comment on the graph of g(x). So, according to the given data the expected value, in dollars, of television B is initially $360 and decreases by $90 each year.
Let the total number of years be 'x'. Then the function g(x) is given by:
g(x) = 90x + 360
Now, compare the functions f(x) and g(x) with the slope-intercept form of the line in order to find the y-intercept.
For f(x) the y-intercept is given by, c = 400
For g(x) the y-intercept is given by, c' = 360
Therefore, the correct option is a) The graph of g(x) has the lesser y-intercept.

State the slope and y-intercept of y=5x+2
Answer:
5 is the slope
(0,2) is the y intercept
Step-by-step explanation:
The equation y = 5x + 2 appears to be written in the y = mx + b form of a linear equation.
m represents slope and b represents the y value of the y intercept.
Here, m = 5 and b = 2.
This means 5 is the slope and (0,2) is the y intercept.

A 2-column table with 4 rows. Column 1 is labeled x with entries 17, 18, 19, 20. Column 2 is labeled y with entries 16, 17, 19, 20.
A 2-column table with 4 rows. Column 1 is labeled x with entries 17, 18, 19, 20. Column 2 is labeled y with entries negative 20, negative 19, negative 18, negative 17.
Answer:
we conclude that the table ''A 2-column table with 4 rows. Column 1 is labeled x with entries 17, 18, 19, 20. Column 2 is labeled y with entries 16, 17, 19, 20'' represents a non-linear function.
Step-by-step explanation:
The nature of whether a function can be linear or non-linear, we must check how the x and y values of the table change. If the first difference between y-values remains the same (constant first difference), then the table will represent a linear function, otherwise not.
Given the x and y entries of the first table:
x y
17 20
18 19
19 18
20 17
From the table, it is clear that as x constantly increases by 1 unit, the y-values are also changing constantly by 1 unit. The first difference between y-values remains the same.
i.e. 19-20=-1, 18-19=-1, 17-18=-1
Thus, this table represents a linear function.
Given the x and y entries of the second table:
x y
17 -16
18 -17
19 -18
20 -19
From the table, it is clear that as x constantly increases by 1 unit, the y-values are also changing constantly by 1 unit. The first difference between y-values remains the same.
i.e. -17-(-16)=-1, -18-(-17)=-1, -19-(-18)=-1
Thus, this table represents a linear function.
Given the x and y entries of the second table:
x y
17 16
18 17
19 19
20 20
From the table, it is clear that as x constantly increases by 1 unit, but the y-values are not changing constantly. The first difference between y-values does not remain the same.
i.e. 17- 16 = 1, 19 - 17 = 2, 20 - 19 = 1
Thus, this table does not represent a linear function. Hence, it is a non-linear function.
Given the x and y entries of the second table:
x y
17 -20
18 -19
19 -18
20 -17
From the table, it is clear that as x constantly increases by 1 unit, the y-values are also changing constantly by 1 unit. The first difference between y-values remains the same.
i.e. -19-(-20)=1, -18-(-19)=1, -17-(-18)=1
Thus, this table represents a linear function.
Therefore, we conclude that the table ''A 2-column table with 4 rows. Column 1 is labeled x with entries 17, 18, 19, 20. Column 2 is labeled y with entries 16, 17, 19, 20'' represents a non-linear function.

one man have 20 oranges in one hod and the get 20 children in the road and he gave 1 orange fore each of them but there is still an orange left in the hod how ?
Step-by-step explanation:
19 kids get an apple each, the 20th kid gets the basket with the apple in it, that’s the answer you want, right?
Well that’s a bogus answer, because how come one kid gets a free basket, and why do you even care that the basket has an apple in it if you don’t get to keep it anyway?
Plus it’s not “all the apples to each one of them” is it? No, it’s one apple each, and different apples are different sizes and degrees of ripeness and maybe some have bruises and it’s just inherently unfair.
Instead, I take 19 apples, and I make applesauce, and I distribute the applesauce using a precision scale so every child gets an exactly equal amount of applesauce, and I keep one apple in the basket, which I keep.
Now, of course it’s not quite “ALL the apples” to the children, but you cannot have your cake and eat it too. I gave an equal amount of apple to each child, and if it was 5% short of all the apples, well, it was, but what of it, that’s the best I can do and still keep one apple in the basket.
Because I am NOT giving one child the basket and having the other nineteen kids complaining about why Johnny got a basket and they didn’t, plus where’s my basket? No, I don’t think so.
Answer:
Give 19 children an orange each = 19 oranges given.
Leave one orange in the basket and give the basket containing that orange to the lucky 20th child.

The vertices of a triangle are p(3,7) Q(7,-6) R(-8,7). Name the vertices of the image reflected across the x axis
Answer:
P'(3,-7) Q'(7,6) R'(-8,-7).
Step-by-step explanation:
Reflection across the x-axis
Given a point P(x,y), its reflection across the x-axis will map to point P'(x,-y), i.e., the y-coordinate gets inverted.
We are given the vertices of a triangle P(3,7) Q(7,-6) R(-8,7). The vertices of the image reflected across the x-axis are:
P'(3,-7) Q'(7,6) R'(-8,-7).
The new triangle has vertices P'Q'R'.
