Find −3/15÷1 3/4. Write your answer as a mixed number in simplest form.

Answers

Answer 1

step one: change the mixed number into an improper fraction:
1 = 4/4, so 1 3/4 = 4/4 + 3/4 = 7/4
step 2: realize that when we divide by a fraction, we are actually multiplying by the reciprocal, or the opposite of the fraction.
step 3: reciprocate the fraction
we are dividing by 7/4, so the reciprocal is 4/7.
step 4: multiply! to do this, you will just multiply across, meaning you will multiply the numerators together and the denominators together.
(-3/15) * (4/7) = -12/105
step 5: simplify
-12/105 is equal to -4/35
hope this helps!

Somerset Corporation just completed its fiscal year ended January 31, 2021. All sales were on account and totaled 650,000 for the year.

Round and enter to one decimal place only.

Answers

The accounts receivable turnover ratio for the year ended January 31, 2021, for Somerset Corporation is 11.3 times.

What is the accounts receivable turnover ratio?

The accounts receivable turnover ratio is a financial measurement of the effectiveness of a company to extend credits and collect debts.

The ratio, which shows the number of times per period that Somerset Corporation can collect its credit sales, can be computed as net credit sales divided by average accounts receivable.

Data and Calculations:

Sales on account = $650,000

Accounts receivable balances:

February 1, 2020 = $60,000

January 31, 2021 = $55,000

Average receivable = $57,500 ($60,000 + $55,000)/2

Accounts receivable turnover ratio = Net credit sales/Average receivables

= 11.3 x ($650,000/$57,500)

Thus, the accounts receivable turnover ratio for the year ended January 31, 2021, for Somerset Corporation is 11.3 times.

The length, breadth and height of a cuboid bear the ratio 5:3:2 . If it's total surface area is 279 cm²,find it's volume.

Answers

Answer:

810 cm^3

Step-by-step explanation:

Since,the l(length) b(breadth) & h(height) of the cuboid bear the ratio 5 : 3 : 2 ,we could assume it as:

l = 5zb = 3zh = 2z

We know that,

Cuboid ( total surface area)= 2lb+2lh+2hb cubic units

So substitute the dimensions we assumed:

We could write it as;

[tex] \rm \: Total \; Surface\; area \: of \: the \; cuboid = 2(5z \times 3z + 3z \times 2z + 2z \times 5z[/tex]

[tex] \implies \rm \: 279 = 31 {z}^{2} [/tex]

Find z

[tex] \rm \implies {z}^{2} = \cfrac{279}{31} [/tex]

[tex] \rm \implies {z}^{2} = 9[/tex]

[tex] \implies \rm \: z = \sqrt{9} [/tex]

[tex] \rm \implies \: z = \sqrt{3 \times 3} = 3[/tex]

Hence, according to the formula,

Cuboid V = lbh

We got the dimensions of the cuboid, i.e.

Then, solve.

Cuboid V = lbh15 cm * 9 cm * 6 cm810 cm^3

Hence,the volume of the cuboid will be 810 cm^3

(f + g)(x) = 2 x²+6x+2

What is composition of function?

The composition of a function is an operation where two functions say f and g generate a new function say h in such a way that h(x) = g(f(x)). It means here function g is applied to the function of x. So, basically, a function is applied to the result of another function.

Given function is:

f ( x ) = 2 x + 2 and g ( x ) = 2 x² + 4 x

So,

(f + g)(x)

= f(x)+g(x)

= 2x+2+2 x² + 4 x

=2 x²+6x+2

Hence, (f + g)(x) = 2 x²+6x+2.

r = rate

c = times in a year ( c = 1 in this equation which is why it's not shown in the actual equation )

find the minimum product of two numbers whose difference is 17.

Answers

A number is an arithmetic value that is used to represent a quantity and calculate it. The two numbers will be 17 and 0, so the product of the two is minimal.

What are Numbers?

A number is an arithmetic value that is used to represent a quantity and calculate it. Numericals are written symbols that represent numbers, such as "3."

Given the difference between the two numbers is 17. Let the first number be zero, then the second number will be 17. Thus, the product of the two numbers will be 0, which is the minimum.

If the first number is further increased such as 1, then the other number will be 18, and the product of the two will be 18, which is greater than zero.

Hence, the two numbers will be 17 and 0, so the product of the two is minimal.

A topic or recent clinical interest is the possibility of using drugs to reduce infarct size is patients who have myocardial infarction within the past 24 hours. Suppose we know that in untreated patients the mean infarct size 25 (ck - g-EQ/m). Furthermore, in 8 patients treated with a drug the mean infarct size is 16. Suppose σ = 10 . Is there statistical evidence the drug is effective in reducing infarct size?

Answers

Yes, there is statistical evidence that the drug is effective in reducing infarct size because p-value is less than the significance value.

How to find hypothetical Evidence?

Let us first define the hypotheses;

Null Hypothesis; H₀: µ = 25

Alternative Hypothesis; H₁: µ < 25

Standard Deviation; σ = 10

Sample mean; x' = 16

Sample size; n = 8

z-score is;

z = (16 - 25)/(10/√8)

z = -2.55

From online z-score table, the p-value is 0.005

Since p-value is less than the significance value, then we reject the null hypothesis and conclude that the drug is effective in reducing infarct size.
