Danika is making necklaces.she has 512 silver beads and 278 blue.About how many more silver than beads does Danika have?
Answer:
234 more silver beads.
Step-by-step explanation:
We have been given that Danika is making necklaces. She has 512 silver beads and 278 blue.
To find the number of silver beads is how much more than blue beads, we will subtract number of blue beads from silver beads.
[tex]\text{Number of more silver beads}=512-278[/tex]
[tex]\text{Number of more silver beads}=234[/tex]
Therefore, Danika has 234 more silver beads than blue beds.

Stan’s savings account has a balance of $1986. After 23 years, what will the amount of interest be at 4% compounded annually?
a.
$2908.93
c.
$2913.93
b.
$2899.93
d.
$794.40
1986*1.04^(23) = 4894.93
4894.93-1986 = 2908.93
Answer is A
Answer:
a. $2908.93
Step-by-step explanation:
We have been given that Stan’s savings account has a balance of $1986. The amount of interest be at 4% compounded annually.
To find the final amount after 23 years we will use compound interest formula.
[tex]A=P(1+\frac{r}{n})^{nT}[/tex], where,
A = Final amount,
P= Principal amount,
r = Annual interest rate in decimal form,
n = Number of times interest in compounded per year,
t = Time in years.
Let us convert our given rate in decimal form.
[tex]4\%=\frac{4}{100}=0.04[/tex]
Upon substituting our given values in above formula we will get,
[tex]A=\$1986(1+\frac{0.04}{1})^{1*23}[/tex]
[tex]A=\$1986(1+0.04)^{23}[/tex]
[tex]A=\$1986(1.04)^{23}[/tex]
[tex]A=\$1986*2.4647155431651442[/tex]
[tex]A=\$4894.9250687259763812[/tex]
To find the amount of interest we will subtract principal amount from final amount.
[tex]\text{Amount of interest}=\$4894.9250687259763812-\$1986[/tex]
[tex]\text{Amount of interest}=\$2908.925068725976\approx 2908.93[/tex]
Therefore, the amount of interest after 23 years will be $2908.93 and option a is the correct choice.

what is the complete factorization of the polynomial below. x^3-3x^2+x-3
Answer:
(x-3)(x+i)(x-i)
Step-by-step explanation:
[tex]x^3-3x^2+x-3[/tex]
We apply grouping method
We group first two terms and last two terms
[tex](x^3-3x^2)+(x-3)[/tex]
Take out GCF x^2 from first group. Also take out 1 from second group
[tex]x^2(x-3)+1(x-3)[/tex]
[tex](x-3) (x^2+1)[/tex]
Now we factor x^2 + 1
We use difference of square formula
a^2 - b^2 = (a+b)(a-b)
x^1 + 1 can be written as [tex]x^2 - (-1)[/tex], the value of -1 is i^2
[tex]x^2 +1 = x^2 -(-1) = x^2 - i^2[/tex]
x^2 - i^2 = (x+i)(x-i)
Final answer is (x-3)(x+i)(x-i)
The complete factorization of the polynomial x^3 - 3x^2 + x - 3 is (x - 3)(x^2 + 1). The process involves grouping and factoring out common terms.
The question asks for the complete factorization of the polynomial x^3 - 3x^2 + x - 3. To factor this polynomial, we are looking for factors of the lowest possible order that will multiply together to give us the original polynomial. Let's first look for a common factor in all the terms. In this case, there isn't a common factor except for 1, so we move on to finding factors through other means such as grouping.
We can attempt to group terms to facilitate the factoring process:
First, consider the polynomial in two parts (x^3 - 3x^2) and (x - 3).Within the first group (x^3 - 3x^2), we can factor out an x^2, which gives us x^2(x - 3).The second group is already in the form (x - 3), mirroring the (x - 3) factor we found in the first group.We then combine these to get the full expression x^2(x - 3) + (x - 3).Next, we can factor out the common (x - 3) term from both groups, obtaining (x - 3)(x^2 + 1).The polynomial x^3 - 3x^2 + x - 3 can now be expressed as the product of (x - 3) and (x^2 + 1). This represents the polynomial in its factored form using real coefficients.

of an estate is to be divided among relatives. Of the remaining estate,
one fifth 1/5
goes to the American Cancer Society. What fraction of the estate goes to the American Cancer Society?
The fraction of the estate that goes to the American Cancer Society is
The American Cancer Society receives 1/35 of the total estate after it has been divided among relatives and other beneficiaries. This is determined by multiplying the fraction of the estate remaining (1/7) by the fraction of that remaining estate going to the Cancer Society (1/5).
Explanation:The question states that six-sevenths, or 6/7, of the estate has been divided among relatives, which leaves one-seventh, or 1/7, of the estate remaining. It is this remaining fraction that is further divided, with one fifth, or 1/5, going to the American Cancer Society. To determine the fraction of the total estate that this represents, we multiply these two fractions together: [tex]1/7 * 1/5 = 1/35.[/tex] Therefore, the American Cancer Society receives one-thirty-fifth of the total estate.

Given the following data:
Cost of diaper = $9.Amount for packages = $36.How to calculate the number of diapers?In order to determine the number of diapers that can be bought with $36, we would set up a direct proportion equation as follows:
$9 = 1 diaper
$36 = X diapers.
Cross-multiplying, we have:
9X = 1 × 36
9X = 36
X = 36/9
X = $4.

Find the standard deviation for each data set. Which set is more variable?
Answer:
Second set.
Step-by-step explanation:
I put the formula of standart deviation in the image below.
x is each data of the list
μ is the data average
N is the amount of elements.
So, for the first list we have:
μ= [tex]\frac{28995+37534+31361+27087+20966+37741}{6}= \frac{183684}{6}=30614[/tex]
DE= [tex]\sqrt{\frac{|28995-30614|^{2}+|37534-30614|^{2}+|31361-30614|^{2}+|27087-30614|^{2}+|20966-30614|^{2}+|37741-30614|^{2}}{6} }[/tex]
= [tex]\sqrt{\frac{2621161+47886400+558009+12439729+93083904+50794129}{6} }[/tex]
= [tex]\sqrt{\frac{207383332}{6} }[/tex]
= [tex]\sqrt{ 34563888.6667 }[/tex]
= 5879.1061.
For the other list of elements:
μ= [tex]\frac{72964+70763+101510+62161+66625+54339}{6}= \frac{428362}{6}=71393.66[/tex]
DE=[tex]\sqrt{\frac{|72964-71393.66|^{2}+|70763-71393.66|^{2}+|101510-71393.66|^{2}+|62161-71393.66|^{2}+|66625-71393.66|^{2}+|54339-71393.66|^{2}}{6} }[/tex]
= [tex]\sqrt{\frac{2465967.71+397732.03+906993934.99+85242010.67+22740118.19+290861427.71}{6} }[/tex]
= [tex]\sqrt{\frac{1308701191.3}{6} }[/tex]

The arcade has 3 pinball machines and 5 video games. If a person wants to play one pinball machine and one video game, how many different combinations of games could that person play?
The number of possible combinations of playing one pinball game and one video game, given there are 3 pinball machines and 5 video games available, is 15.
Explanation:The subject of this question is combinatorics, a part of Mathematics that deals with combination and arrangement of objects. The question in essence is asking about the number of combinations one can play on a pinball machine and a video game in an arcade.
In the given context, there are 3 pinball machines and 5 video games. If a person wants to play one of each (one pinball game and one video game), we can calculate the number of combinations by simply multiplying the number of options for each game. That is, 3 pinball machines multiplied by 5 video games equals 15 different combinations.
So, there are 15 different combinations of games a person can play when selecting one pinball and one video game from the given sets.
