Does this look correct?

Answer:

{60,63,87}

Step-by-step explanation:

At a sale, suits were sold for $72 each and this price was 45% of a suit's original price which means that suit originally cost $160.

This is referred to as a number or ratio that can be expressed as a fraction of 100.

Selling price = $72 which is 45% of a suit's original price.

Therefore, 45/100 × X =  $72.

45X = 7200

X = 7200/45 = $160.

What is compound interest?

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.

Let A be the final amount.

Principal = $2000

r = rate = 5%

n = number of compounding in a year = 4

t = number of years the principal will be compounded = 30

The formula for compound interest:

[tex]A=P(1 +\frac{r}{n})^{nt}[/tex]

[tex]A=2000(1 +\frac{0.05}{4})^{4 \times 30}[/tex]

A = $8,880.43

I will have $8,880.43  in the account in 30 years.

2. two complex solutions, the correct answer is C.

Step-by-step explanation:

A two sigma confidence interval is created whenever our alternate hypothesis does not equal a value.

For example if

[tex]h_{o} = 0.36[/tex]

and

[tex]h _{a} ≠0.36[/tex]

We used a two sigma confidence interval because we are thinking a portion is either below 0.36 or above 0.36.

When solving these probability for the p value, multiply the inital result by 2 to get the p value

The 2 sigma confidence interval is a principle that states that a result will be considered significant if 95% of the population is two standards deviation from the average value.

The two-sigma confidence level states that 95% of the values obtained in the results from a population should be within2 deviations from the mean. Anything below this acceptable percentage is not considered the 2-sigma confidence level.

If 68% of the score are within 1 standard deviation from the mean, then that will be considered the 1-sigma rule. If 99.7% of the score is 3 standard deviations from the mean then we can refer to that as the 3-sigma confidence interval.

Rodrigo will accrue 1023.17 interest during the 4.5-year non-payment period.

The simplest way to compute interest is as a percentage of the principal. For instance, if you agreed to borrow $100 from a buddy with 5% interest, the interest you would pay would only be 5% of $100: $100(0.05) = $5. Simple Interest (S.I.) is a way for figuring out how much interest will accrue on a specific principal sum of money at a certain rate of interest. For instance, if someone borrows Rs. 5000 at a rate of 10 p.a. for two years, they will pay S.I. on the borrowed money for those two years.

Given,

For calculating interest:

Interest = Principal ×rate × time

Principal = 5300

Rate = 0.0429

Time = 4.5

Interest = 5300 × 0.0429 × 4.5

Interest = 1023.17

Answer: This equation, when simplified would be x = 4

Step-by-step explanation:

That's what I believe it is

The simplified form of the expression ( ⁴√( 8³ ) )^1/3 in rational exponents forms is 8^1/4.

Given the expression in the question;

( ⁴√( 8³ ) )^1/3

To convert to rational exponent form, apply the exponent rule;

ⁿ√aˣ = a^x/n

Hence;

( ⁴√( 8³ ) )^1/3 = 8^3/4

So we have,

( 8^3/4 )^1/3

Now, apply the power rule to multiply the exponents.

(a^m)^n = a^mn

( 8^3/4 )^1/3

8^( 3/4 × 1/3 )

8^( 3×1/4×3 )

Multiply 3 and 1

8^( 3/4×3 )

Multiply 4 and 3

8^( 3/12 )

250b calories in b, bars 15c calories in c, carrots

Step-by-step explanation:

a. The shape of the distribution is normal, by the Central Limit Theorem.

b. The mean is of: 0.23.

c. The standard error is of: 0.125, meaning that the sample proportions differ by around 0.125 from the mean of 0.23.

d. The probability is of: 0.2877 = 28.77%.

By the Central Limit Theorem, as each sample has at least 10 successes and at least 10 failures, the shape of the distribution is normal.

For each sample, the mean and the standard error are given as follows:

Hence for the distribution of differences, the mean and the standard error are given as follows:

Using the z-score formula, the probability that the difference is greater than 30 is one subtracted by the p-value of Z when X = 0.3, hence:

Z = (0.3 - 0.23)/0.125

Z = 0.56

Z = 0.56 has a p-value of 0.7123.

1 - 0.7123 = 0.2877 = 28.77%.

It takes 15 minutes for 1 bracelet. 15 minutes multiplied by 21 bracelets is 315. Lmk if you need more help

Answer: 315 minutes.

Step-by-step explanation:

To solve this, we need to find out how long it takes to make one bracelet first.

If it takes 45 minutes to make 3 bracelets, we need to divide 45 by 3, which gives us 15.

This means it takes 15 minutes to make one bracelet.

Now, we need to multiply 15 by 21.

15 x 21 = 315.

This means it will take 315 minutes to make 21 bracelets.
