If a hen and a half lay an egg and a half in a day and a half, how many eggs will half a dozen hens lay in half a dozen days?
Answer:
28 eggs
Step-by-step explanation:
It takes a hen and a half to lay an egg and a half in a day and a half - this means it takes 1 hen to lay 1 egg in a day and a half. Therefore, 1 hen will lay 4 eggs in 6 days, and 7 hens will lay 28 eggs in 6 days.
Answer:
18
Step-by-step explanation:
in 6 days there is 144 hours divide that by 36 (a day and a half) would be 4 so 4 days of the 6 the hens would lay an egg and a half. there is 6 hens divide that by 1.5 would be 4 times that together would be 16 but they laid an egg and a half so add .5x4 so add 2 to the 16 which gives 18

You are putting together your first post-graduation budget. Your take-home or net pay will
be $2,500 per month. You estimate your monthly costs to be rent of $800, car payment of
$350, car insurance of $150, car maintenance of $50, entertainment of $500, food expense of
$250, cable bill of $75, mobile phone of $100, student loan payment of $100 and other
expense of $300. How would you describe your budget after analyzing all of your income and
expenses?
A. You have a surplus of $175
B. You have a deficit of $175
C. You have a deficit of $2,675
D. You have a surplus of $2,500
Answer:
B) you have a deficit of 175
Step-by-step explanation:
Add up all of your costs per month and subtract that from your net pay.
ie: 2500-2675=-175
Since the answer is negative, and you don't make the extra $175 dollars needed to cover all your costs, it is a deficit.
If you made $2675 a month and your total expenses were 2500, then you would have a surplus of $175. Because it is money that you still have and don't need to use for anything specific.
Description of your budget after analyzing all of your income and
expenses you have a deficit of 175. which is the correct answer would be an option (B).
What is the Subtraction operation?Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
Add up all of your monthly expenses and remove them from your net salary.
⇒ 2500 - 2675
Apply the subtraction operation, and we get
⇒ -175
It is a deficit since the answer is negative and you do not make the extra $175 needed to pay all of your costs.
Thus, the description of your budget after analyzing all of your income and
expenses you have a deficit of 175.

(a) An article in a medical journal suggested that approximately 14% of such operations result in complications. Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.08
This question is incomplete, the complete question is;
Surgical complications: A medical researcher wants to construct a
99.5% confidence interval for the proportion of knee replacement surgeries that result in complications.
- An article in a medical journal suggested that approximately 14% of such operations result in complications. Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.08?
Answer: a sample of operations needed is 149
Step-by-step explanation:
Given that;
confidence interval = 99.5% = 0.995 so
margin of error E = 0.08
p = 14% = 0.14
now we obtain the critical value of z t the 99.5 confidence interval
∝ = 1 - confidence interval
∝ = 1 - 0.995
∝ = 0.005
∝/2 = 0.0025
obtaining the area of probability in the right tail
Area of probability to the right is = 1 - 0.0025 = 0.9975
from probability table; critical value of t =2.81
using the formula
n = p( 1 - p ) [ (z_∝/2)/E)² ]
so we substitute
n = 0.14 ( 1 - 0.14 ) [ 2.81 / 0.08 )²
n = (0.14 × 0.86 ) × 1233.7656
n = 148.5453 ≈ 149
Therefore , a sample of operations needed is 149

Answer:
6. Stretched horizontally by a factor of 1/2 and stretched vertically by a factor of 4.
7. Stretched horizontally by a factor of 1/3 and translated 4 units down.
Step-by-step explanation:

[tex]\textsf{For $a > 0$}[/tex]
[tex]f(x+a) \implies f(x) \: \textsf{translated $a$ units left}[/tex]
[tex]f(x-a) \implies f(x) \: \textsf{translated $a$ units right}[/tex]
[tex]f(x)+a \implies f(x) \: \textsf{translated $a$ units up}[/tex]

[tex]f(ax) \implies f(x) \: \textsf{stretched parallel to the $x$-axis (horizontally) by a factor of $\dfrac{1}{a}$}[/tex]

[tex]f(-x) \implies f(x) \: \textsf{reflected in the $y$-axis}[/tex]
Question 6Parent function:
[tex]f(x)=\sqrt{x}[/tex]
Stretched horizontally by a factor of 1/2:
Multiply the x-variable by 2:
[tex]\implies f(2x)=\sqrt{2x}[/tex]
Stretched vertically by a factor of 4:
Multiply the function by 4:
[tex]\implies4f(2x)=4\sqrt{2x}[/tex]
Question 7Parent function:
[tex]f(x)=\lfloor x \rfloor[/tex]
Stretched horizontally by a factor of 1/3:
Multiply the x-variable by 3:
[tex]\implies f(3x)=\lfloor 3x \rfloor[/tex]
Translated 4 units down:
Subtract 4 from the function:
[tex]\implies f(3x)-4=\lfloor 3x \rfloor-4[/tex]

If £25 = 650 rubles, how many £ are in 780 rubles?
Answer:
30
Step-by-step explanation:
25£ : 650 rubles
x£ : 780 rubles
25/x = 650/780
(cross multiply)
650x = 25×750
650x = 18 750
divide 18 750 by 650
which is = 30
thus x = 30
780 rubles id equals to £29.64.
What is unitary method?The unitary method is a technique for solving a problem by first finding the values of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the given question
We have
£25 = 650rubles
⇒ 1 rubles = [tex]\frac{25}{650}[/tex] = £0.038
Therefore,
780 rubles = £0.038 × 780 = £29.64
Hence, 780rubles id equals to £29.64.

Given mn, find the value of x.
104°
Help me please
Answer:
x = 104°
Step-by-step explanation:
Hello!
104° and x° are called alternate interior angles because they are in between the two parallel lines, and on the opposite sides of the transversal line.
Since they are alternate interior angles, they are congruent in measure.
Therefore: x = 104°
With alternate angles concept, the value of x from the given parallel lines is 104°.
Given that, straight line m parallel to straight line n and t is the transversal.
When a transversal connects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines. At two different locations, the transversal passes through the two lines that are coplanar.
Here, x°=104° (Interior alternate angles are equal)
Therefore, the value of x from the given parallel lines is 104°.

Complete question :
Of 50 employees of a store located in downtown Boston, 18 people take the subway to work, 12 take the bus, and 7 people take both the subway and the bus. How many employees (a) Take the subway or the bus to work? employees (b) Take only the bus to work? employees (c) Take either the bus or the subway to work (but not both)? employees (d) Get to work by some other means? employees
Answer:
23 ; 5 ; 16 ; 13
Step-by-step explanation:
Given that:
Subway (s) = 18
Bus (b) = 12
Subway and bus = 7
a) Take the subway or the bus to work?
Number of subway + number of bus - (subway and bus)
18 + 12 - 7 = 23
(b) Take only the bus to work?
Number of bus - (subway and bus)
12 - 7 = 5 employees
(c) Take either the bus or the subway to work (but not both)?
Number of bus - (subway and bus) + Number of bus - (subway and bus)
(12 - 7) + (18 - 7) = 5 + 11 = 16 employees
(d) Get to work by some other means?
Total employees - (subway + bus + subway and bus)
50 - (18 + 12 + 7)
50 - 37
