Answer:
25$
Step-by-step explanation:
If 4 stickers cost 2$, then each sticker would cost .50$
50(.5)=25
You would have spent 25$
Answer:
$25
Step-by-step explanation:
For every 2 sticks it's $1, so you divide 50 by 2 and get 25, so it's $25..... I think

I need to understand question 14 and 15 and the last one cut off for tens in one
Question # 14
Given the numbers
10 11 12 13 14 15 16 17 18 19 20
Let 'x' be the number
The condition breakdown:
I am less than 20.
So the number 'x' must be less than 20 i.e. x < 20I am more than 13.
So the number 'x' must be greater than 13 i.e. x > 13I am less than 17.
So the number 'x' must be less than 17 i.e. x < 17Finally:
I am 4 more than 12
i.e. 12+4 = 16
Thus, the number is x = 16
Question # 15
Part a)
Given the numbers
10 11 12 13 14 15 16 17 18 19 20
Let 'x' be the number
The condition breakdown:
I am more than 10.
x > 10I am less than 20.
x < 20I am more than 12.
x > 12I am less than 15.
x < 15As the numbers left after all the conditions are fulfilled are 13 and 14.
But the last condition is, of the numbers that left, the number is greater than all the remaining numbers.So, from the remaining number 13 and 14;
14 > 13
Thus, the number x = 14
Part b)
Drawing the number 14 in the place value:

The temperature fell from 0°F to 6 3/5 F below 0f in 2 1/5 hours. What was the temperature change per hour?
Answer:
The rate is -3°F per hour.
Step-by-step explanation:
The rate of change of the temperature per hour, will be equal to the quotient between the total change in temperature and the time it took for the change.
We know that the initial temperature is 0°F
The final temperature is -(6 + 3/5)°F
Then the change in the temperature will be:
Final temperature - initial temperature = -(6 + 3/5)°F - 0°F = -(6 + 3/5)°F
We know that this change took a total of (2 + 1/5) hours, then we can conclude that the rate will be:
Rate = -(6 + 3/5)°F/(2 + 1/5) hs = -(30/5 + 3/5)°F/(10/5 + 1/5) hs
= -(33/5)°F/(11/5)hs = -(33/11) °F/hs = -3 °F/hs
This means that the rate of change is -3°F per hour, so the temperature decreases 3 °F for each hour that passes.

Alina and Asim share 210 dollars In the ratio 2:5 how much money did each of them get ?
Answer:
Let Alina share be 2x and asking share be 5x
then, 2x+5x =210 dollars
7x =210 dollars
x=30 dollars
then share of Alina = 2x = 2 * 30 = 60 dollars
and share of asim= 5x = 5 * 30 = 150 dollars

Angie divides the polynomial function f (x)+x3+3x2-7x-21 by (x+3) what can she conclude from the fact that the remainder is equal to 0
Answer:
Yes, and if you divide x^3+3x^2-7x-21 with x+3 you will result in x^2-7
Step-by-step explanation:
Hope this helps
And I like your profile pic
The given polynomial is divisible by x+3 because f(-3)=0
So , the remainder is equal to 0
Her conclusion is correct.
Given :
Angie divides the polynomial function
[tex]f (x)=x^3+3x^2-7x-21[/tex] by (x+3)
Apply remainder theorem to check whether the remainder is equal to 0
If a polynomial p(x) is divisible by (x-a), the remainder obtained is P(a)
x+3 is the divisor
Lets set the divisor =0 and solve for x
[tex]x+3=0\\x=-3[/tex]
Now we plug in -3 for x in given f(x) and see whether f(-3) =0
[tex]f (x)=x^3+3x^2-7x-21\\f (-3)=(-3)^3+3(-3)^2-7(-3)-21\\f(-3)=-27+27+21-21\\f(-3)=0[/tex]
So, f(-3)=0 and hence the remainder is 0
Her conclusion is correct

Given that the population proportion is 0.82, the Normal distribution will provide a good approximation to the true sampling distribution of the sample proportion as long as:________.
A) n> 13.
B) n> 30.
C) n> 56.
D) n > 100.
Answer:
Then solution as long as n ≥ 56
Step-by-step explanation:
The Normal distribution will provide a good approximation to evaluate proportion tests when the following conditions are met:
n*p₀ > 10
n*q₀ > 10
As p₀ = 0,82 q₀ = 0,18 n = 13 30 56 and 100
We test:
A) n = 13 n*q₀ = 13*0,18 = 2,34 2,34 < 10
B) n = 30 n*q₀ = 30*0,18 = 5,4 5,4 < 10
C) n = 56 n*q₀ = 56 * 0,18 = 10,08
n*p₀ = 56 * 0,82 = 45,92
D) n = 100 n*q₀ = 18
n*p₀ = 82
If we test 55 we find that 55*0,18 = 9,9
Then solution as long as n ≥ 56
True or false:
a. A product of two self-adjoint matrices is self-adjoint.
b. If A is self-adjoint, then Ak is self-adjoint.
Justify your conclusions
Answer:
Option a is "False".
Option b is "True".
Step-by-step explanation:
In point a:
Prove AB=BA
[tex]A=\left[\begin{array}{cc}1&2\\4&5\end{array}\right] \\\\B= \left[\begin{array}{cc}2&1\\8&5\end{array}\right][/tex]
Solve L.H.S part:
[tex]AB= \left[\begin{array}{cc}1&2\\4&5\end{array}\right] \times \left[\begin{array}{cc}2&1\\8&5\end{array}\right][/tex]
[tex]= \left[\begin{array}{cc}2+16 &1+10\\8+40&4+25\end{array}\right]\\\\\\= \left[\begin{array}{cc}18 &11\\48&29\end{array}\right][/tex]
Solve R.H.S part:
[tex]BA= \left[\begin{array}{cc}2&1\\8&5\end{array}\right] \times \left[\begin{array}{cc}1&2\\4&5\end{array}\right][/tex]
[tex]= \left[\begin{array}{cc}2+4 &4+5\\8+20&16+25\end{array}\right]\\ \\ \\= \left[\begin{array}{cc}6 &9\\28&41\end{array}\right][/tex]
So, [tex]AB \neq BA[/tex]
In point b:
[tex]A^{*} =A\\\\(Ak)^{*} =A^k[/tex]
if [tex]k= 1[/tex]it holds the trivially [tex]A^{*}=A ...........(1)[/tex]
by assuming that if it is true for [tex]k=n-1[/tex]
that is
[tex](A^{n-1})^{*}= A^{n-1}............(2) \\\\ if \ k=n\\\\\to (A^{n})^{*} = (A^{n-1} \cdot A^1)^{*} = A^{*}(A^{n-1})^{*} \\\\\to A(A)^{n-1}[/tex] use above equations
[tex]\to A^{n-1+1} \\\\ \to A^{n}[/tex]
that's why it is true.

Please check the explanation.
Step-by-step explanation:
We know that
An expression can not be a polynomial if any term has a negative exponentAn expression can not be a polynomial if any term has a fraction exponentAn expression can not be a polynomial if any term contains division by a variable.2)
Given the expression
f(x) = 3x + 4/3 x³ - 7
The given expression is a polynomial with degree 3 (highest power of any variable) and having 3 terms
3)
Given the expression
g(x) =- 5x³ + x - 3/x
The given expression is NOT a polynomial as any term of a polynomial can not have exponent as -1.
For example, the term 3/x or 3x⁻¹ has negative exponent -1.
Thus, g(x) =- 5x³ + x - 3/x
4)
Given the expression
h(x) =x³√5 + x - 3
The given expression is a polynomial with degree 3 (highest power of any variable) and having 3 terms
5)
Given the expression
k(x)=25x²-x³+x⁵
The given expression is a polynomial with a degree of 5 (highest power of any variable) and having 3 terms.

A medication contains 5 milligrams/milliliter, and a patient is taking 1 teaspoon of it 3 times daily. How many milligrams of medication is the patient receiving per day?
options:
5 milligrams
7.5 milligrams
75 milligrams
100 milligrams
Answer:
Answer: 75 milligrams
Step-by-step explanation:
The medication contains 5 milligrams/milliliter.
The patient is given 1 teaspoon of the medication 3 times a day. Since 1 teaspoon is approximately equal to 5 milliliters, then the patient takes 3*5 = 15 milliliters of the medication per day.
Each milliliter contains 5 milligrams, thus the patient receives 15*5 = 75 milligrams of medication per day.
Answer: 75 milligrams
