First, find the middle of the data and you get 4 numbers in each side, then find the median for both group: 100,120,130,188 and for 196,220,265,300, for the group 1 that median is Q1 and for the second the median is Q3, now the interquartile range is=Q3-Q1
so,Q1=(120+130)/2=125
Q3=(220+265)/2=242.5
IQR=Q3-Q1=242.5-125=117.5

Sam deposits 12,500 each year into a retirement account with a %3 simple interest rate. If he deposits the same amount each year

alina1380 [7]

The money in bank after 4 years will be $\bold{\$68125}$

<u>Solution:</u>

Given, Sam deposits 12,500 each year into a retirement account with a $\%3$ simple interest rate.

He deposits the same amount each year, we have to find the amount of money will he have at the end of his fourth year.

We know that, $\text { Simple Interest }=\frac{\text {Amount } \times \text { Rate } \times \text { Time}}{100}$

So, now let us find S.I after $1^{\mathrm{st}} \text{ year } =\frac{12500 \times 3 \times 1}{100}=125 \times 3=375$

Then, after $1^{\text {st }}$ year he adds 12,500 again, which means amount doubles $\rightarrow$ S.I also doubles as rate and time of 1 year gap are constant.

Then, S.I for $2^{\text {nd}} \text {year }=375 \times 2=750$

Amount and corresponding S.I for 4 years will be,

$\begin{array}{l}{12500 \rightarrow 375} \\\\ {25000 \rightarrow 750} \\\\ {37500 \rightarrow 1125} \\\\ {50000 \rightarrow 1500} \\\\ {62500 \rightarrow 1875}\end{array}$

Now, total balance = amount after $4^{th}$ year + sum all simple interests made up to now.

Total balance $= 62500 + (375 + 750 + 1125 + 1500 + 1875) = 62500 + 5625 = 68125$

Hey can you please help me posted picture of question

The number of roots of a quadratic function can be determined from its discriminant.

If Disc> 0, the function has two distinct roots
If Disc = 0, the function has a repeated root
If Disc < 0, the function has no real root.

The discriminant can be calculated as:

Disc = b² - 4ac

For the given equation:

Disc = 9 - 4(2)(1) =1

Since the value of discriminant is positive, the function will have two distinct roots.

So, the answer to this question is option B

So the recipe calls for 96 grams of sugar, and one cup is 128 grams of sugar.

She added a half of a cup, and as they said before one cup was 128 grams of sugar. So half of 128 is 64. So she added 64 grams of sugar. The recipe needs 96 grams so 64 grams is not enough sugar.

So 96 grams minus 64 equals 32 grams. So she still needs 32 grams of sugar.

So since the answers are all in cups, we must convert our answer from grams to cups.

So we have 32 grams of sugar left and to convert it we must put the 32 grams out of one cup. Once again one cup is 128 grams of sugar. So the amount of cups we need is 32/128 (fraction).

Also we need to simplify our fraction to completely answer the question. So we divide the numerator and denominator by 32.

So the final answer is 1/4. So the answer is D or the last answer out of the multiple choice.
