Answer:

0.0794%

Subtract the 26.3 from 100 and get the amount for water giving you 73.7

Divide both from their molar masses

26.3/74.55=0.3528

73.7/18.016=4.0908

Add both answers, 0.3528+4.0908=4.4436

Divde the KCl total from the the total moles which gives you your final amswer

Step-by-step explanation:

Step one:

given

a man buys eggs at RS 9.60 per dozen

what is the unit cost of the dozen of eggs?

unit cost = 9.60/12

= $0.8 per egg

He sold 20 eggs for RS 18

the unit selling price = 18/20

=$0.9 per egg

the percent gain is

=0.8/0.9*100

=0.888*100

=88.89%

Answer:

1.97

Step-by-step explanation:

Following are the solution to the given points:

Assume A, P, and B is the masses of apples, pears, and basket, respectively.

[tex]\to W = 4A + 6P + B[/tex]

Calculating the mean of W:

[tex]\to \bold{W = E(W) }[/tex]

         [tex]\bold{= E(4A + 6P + B)} \\\\ \bold{= 4E(A) + 6E(P) + E(B)}\\\\\bold{= 4 \times 4.72 + 6 \times 5.41 + 13.52} \\\\ \bold{= 18.88 + 32.46 + 13.52} \\\\ \bold{= 64.86 }[/tex]

Calculating the variance of W:

[tex]\to \bold{W=Var(W)}\\\\[/tex]

         [tex]\bold{= Var(4A + 6P + B)}\\\\ \bold{= 42 Var(A) + 62 Var(P) + Var(B)}\\\\\bold{= 16 \times 0.22 + 36 \times 0.182 + 1.882}\\\\ \bold{= 3.52 + 6.552 + 1.882}\\\\ \bold{= 5.3408}[/tex]

Calculating the standard deviation of W:

[tex]\to \bold{W= \sqrt{5.3408}= 2.311017}[/tex]

The linear combination of Normal random variables is known to follow the normal distribution.

[tex]\to \bold{W \sim N(64.86 , 2.311017)}[/tex]

Calculating the Probability of the Total Weight is more difficult.[tex]\to \bold{67 = P(W > 67)}[/tex]  

         [tex]\bold{= P[ Z > \frac{(67 - 64.86)}{ 2.311017}]}\\\\\bold{= P[Z > 0.93]}\\\\\bold{= 0.1762}[/tex] (Using Standard Normal distribution)

Therefore, the final answer is "64.86, 2.311017, and 0.1762".

Answer:

There will be 18 grams left after 12 hours.

Step-by-step explanation:

Half-life is the amount of time it take for a cell to turn from one condition to another.

To find the amount of grams for the first 6 hours.

72 ÷ 2= 36

Now, since 6 x 2 = 12, we need to divide 36 by 2 to find the next half-life.

36 ÷ 2 = 18

Therefore, there will be 18 grams left after 12 hours.

Hello

Step-by-step explanation:

Answer:

1. Couples tickets: $8

   Individual tickets: $4

2. Song download cost: $2

    Movie download cost: $15

Step-by-step explanation:

You can solve both of these questions by doing system of equations.

Let's start with question 1.

There are 2 variables in this equation:

- Couples tickets price: let's represent these with the letter C

- Individual tickets price: let's represent these with the letter K

Writing the two equations would look this these:

5c + 2k = 48

3c + 2k = 32

Next, isolate a variable. I am going to isolate K in the first equation.

[tex]2k = -5c + 48 \\k = -\frac{5}{2}c + 24[/tex]

Now that we isolated a variable we can plug that back in to the second equation:

[tex]3c + 2(-\frac{5}{2}c + 24) = 32\\3c - \frac{10}{2}c + 48 = 32\\3c -5c + 48 = 32\\-2c + 48 = 32\\-2c = -16\\c = 8[/tex]

We found that c is equal to 8 so we can put that back in to an equation to solve for k.

5(8) + 2k = 48

40 + 2k = 48

2k = 8

k = 4

Therefore, the price for couples tickets is $8 and the price for individual tickets is $4.

Check #1:

5(8) + 2(4) = 48

40 + 8 = 48

48 = 48

3(8) + 2(4) = 32

24 + 8 = 32

32 + 32

Now, let's go on to question 2.

There are 2 variables in this equation:

- Price of songs downloaded: let's represent these with S

- Price of movies downloaded: let's represent these with M

Writing the two equations would look like this:

15s + 11m = 195

15s + 8m = 150

There is a simple way to answer this system, however.

If you change the bottom equations signs to negative you can minus the second equation from the first equation like this:

15s + 11m = 195

-(15s +8m = 150)

Minus them to get this equation:

3m = 45

Solve

m = 15

We have found that each movie download costs $15, now let's plug this back into an equation:

15s + 11(15) = 195

15s + 165 = 195

15s = 30

s = 2

Each song costs $2 to download.

Check #2:

15(2) + 11(15) = 195

30 + 165 = 195

195 = 195

15(2) + 8(15) = 150

30 + 120 = 150

150 = 150

I hope this helps!!

Step-by-step explanation:

In a roll of two dice ;

The sample space = (Number of faces on die)^number of dice rolled = 6^2 = 36

The total possible outcome = sample space = 36

The probability of an event (A) :

P(A) = number of required outcome / number of total possible outcomes

find the probability for total: a) 1,

P(total of 1)

Number of 1 total = 0

Hence, P(total of 1) = 0

b) 4 or 6;

Number of 4 total = 3

Number of 6 total = 5

3 /36 + 5 / 36 = 8/36 = 2/9

c) <13

P(total < 13)

Number of total < 13 = 36

36 / 36 = 1

Subtraction property of equality

Step-by-step explanation:

Given the equation;

2x + (x+5) = 41

open the parenthesis;

2x+x + 5 = 41 (Associative property)

3x+5 = 41

Subtract 5 from both sides

3x + 5 = 41

3x + 5- 5 = 41 - 5 (Subtraction property of equality)

3x = 36

Divide both sides by 3;

3x/3 = 36/3

x = 12 (Division property of equality)

Hence the required property is Subtraction property of equality

Complete question is;

Elle Measured the height of a plant, in inches,Every week for four weeks after planting it.

The height of the plant, h, in inches, Can be modeled by the function h(t) = 1.5t + 3, where t represents the time in weeks.

Based on this model, what is the best prediction for the height of the plant after 12 weeks?

A 16.5 inches

B 21 inches

C 22.5 inches

D 27.3 inches

Answer:

Option B: 21 inches

Step-by-step explanation:

We are given the function h(t) = 1.5t + 3, where t represents the time in weeks.

At t = 0;

h(0): 1.5(0) + 3 = 3inches

At t = 1;

h(1): 1.5(1) + 3 = 4.5 inches

Thus, after 12 weeks, height will be;

h(12): 1.5(12) + 3 = 21 inches

Option B is correct

Answer:

47.1 cm

Step-by-step explanation:

The circumference of a circle is denoted by C = 2πr, where r is the radius.

Here, we see that the given radius is 7.5, so r = 7.5 cm. We also are given that we need to use the approximation 3.14 for π, so plug all these into the formula:

C = 2πr

C = 2 * 3.14 * 7.5 = 47.1

To round this to the nearest hundredth... well, there's no hundredth place, so we can leave this as is or just write 47.10 cm.

Thus, the circumference is 47.1 cm.

Answer:

Pretty sure its D.

Step-by-step explanation:

Whenever I made t something higher than 0 I got something less than 40|

(Sorry if I didn't make it in time and if I did I'm taking the same test rn gl homie)

The value of function W(t) will be less then 40 if t > 0 thus option (D) is correct.

A certain kind of relationship called a function binds inputs to essentially one output.

In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

As per the given function,

W(t) = 40[tex]e^{-0.35t}[/tex]

By the law of indices,

W(t) = 40/[tex]e^{.035t}[/tex]

When t > 0 the value of  [tex]e^{.035t}[/tex] > 1

Thus, t > 0 the value of W(t) < 40

Hence "The value of function W(t) will be less then 40 if t > 0".

Answer:

1/3/4 are all correct

Step-by-step explanation:

For Paul to select 1 of his 4 children, the simulation tool must have the possibility of giving a result of 1/4 (i.e. 1 in 4 children). The simulation tools capable of these results are: (1), (3) and (4)

To determine which simulation tool is correct for the situation, we simply put each option to test.

Option (1)

[tex]Sections = 12[/tex]

[tex]Sub= 3[/tex]

Here, the simulation is done by calculating the probability of each subsection.

The probability is:

[tex]Pr = \frac{Sub}{Sections}[/tex]

[tex]Pr = \frac{3}{12}[/tex]

Simplify

[tex]Pr = \frac{1}{4}[/tex]

Option 2

[tex]Chips =12[/tex]

[tex]Sections = 2[/tex]

Here, the simulation is done by calculating the probability of each section.

The probability is:

[tex]Pr = \frac{Sections}{Chips}[/tex]

[tex]Pr = \frac{2}{12}[/tex]

Simplify

[tex]Pr = \frac{1}{6}[/tex]

Option 3

A standard deck has:

[tex]Cards = 52[/tex]

[tex]Suit = 13[/tex]

Here, the simulation is done by calculating the probability of each suit.

The probability is:

[tex]Pr = \frac{Suits}{Cards}[/tex]

[tex]Pr = \frac{13}{52}[/tex]

Simplify

[tex]Pr = \frac{1}{4}[/tex]

Option 4

[tex]Coins = 2[/tex]

Here, he needs to toss the coin 2 times. So, the possible sample space are:

[tex]S = \{HH, HT, TH, TT\}[/tex]

The probability of one of the outcomes is:

[tex]Pr = \frac{1}{n(S)}[/tex]

Where:

[tex]n(S) = 4[/tex] ---- number of outcomes

So:

[tex]Pr =\frac{1}{4}[/tex]

Option 5:

[tex]Sides =6[/tex]

The probability of getting 1 of the 6 faces is:

[tex]Pr = \frac{1}{6}[/tex]

Paul can only use simulations that give 1/4. Hence, (1), (3) and (4) are correct because they all equal 1/4.
