[tex]2 \times \dfrac{1}{2} \: kg \\ \\ = \frac{5}{2} kg \\ \\ = 2.5kg[/tex]kg of biscuit cost $ 15 .

We have been asked to find the cost of 2Kg of biscuits.

First Let's find the cost of 1Kg biscuit

[tex] \tt\implies \: cost \: of \: 1 \: kg \: biscuit \: = \dfrac{15}{2.5} \\ \\ \: \: \tt\implies \: cost \: of \: 1 \: kg \: biscuit \: = 6 \: dollar[/tex]

Then Cost of 2Kg biscuit would be

[tex] \tt\implies \: cost \: of \: 1kg \: biscuit \: = 2 \times 6 \\ \\ \tt\implies \: cost \: of \: 1kg \: biscuit \: = \: 12 \: dollar[/tex]

Hence, the cost of 2 kg biscuit is 12$ .

Answer:

8-1/2x

Step-by-step explanation:

8 1/3 = 25/3

25/3 - 1/2x - 1/3

25/3 - 1/3 - 1/2x

24/3 - 1/2x

8 - 1/2x

Final Answer: 8 - 1/2x

Answer: Your equation will look like this, where “N” is the number and “R” is the intermediate result

N−(N∗30/100)=R

R+(R∗50/100)=525

Simplifying and solving for R, we get:

R+0.5R=525 ← reducing 50/100

1.5R=525 ← combining R terms

R=350 ← dividing both sides by 1.5

Now, we need to solve for N:

N−0.3N=350 ← reducing 30/100

0.7N=350 ← combining N terms

N=500 ← dividing both sides by 0.7

The test statistics is used to determine if the anxiety medication can happen under a null hypothesis

The test statistics that is an appropriate hypothesis test is [tex]z =\frac{0.35 - 0.40}{\sqrt{\frac{0.35(1 - 0.35)}{60} + \frac{0.40(1 - 0.40)}{85}}}[/tex]

40 milligrams of medication

Patients = 60

Lower stress level patients = 21

The mean of this medication is:

[tex]\bar x = \frac{x}{n}[/tex]

So, we have:

[tex]\bar x_1 = \frac{21}{60}[/tex]

[tex]\bar x_1 = 0.35[/tex]

75 milligrams of medication

Patients = 85

Lower stress level patients = 34

The mean of this medication is:

[tex]\bar x = \frac{x}{n}[/tex]

So, we have:

[tex]\bar x_2 = \frac{34}{85}[/tex]

[tex]\bar x_2 =0.4[/tex]

The test statistic is then calculated as:

[tex]z =\frac{\bar x_1 - \bar x_2}{\sqrt{\frac{\bar x_1(1 - \bar x_1)}{n_1} + \frac{\bar x_2(1 - \bar x_2)}{n_2}}}[/tex]

The equation becomes

[tex]z =\frac{0.35 - 0.40}{\sqrt{\frac{0.35(1 - 0.35)}{60} + \frac{0.40(1 - 0.40)}{85}}}[/tex]

Hence, the test statistics that is an appropriate hypothesis test is [tex]z =\frac{0.35 - 0.40}{\sqrt{\frac{0.35(1 - 0.35)}{60} + \frac{0.40(1 - 0.40)}{85}}}[/tex]

Answer:

the inequality sign changes when dividing by a negative number

Answer:

x < -7

Step-by-step explanation:

-6x > 42

First you want to divide off -6 to isolate x

[tex]\frac{-6x}{-6}[/tex] = [tex]\frac{42}{-6}[/tex]

keeping in mind what you do to one side of the equation you have to do to the other side.

Whenever you divide with a negative number the inequality sign flips from < to > and vice versa.

after you divide off the -6 your left with x < [tex]\frac{42}{-6}[/tex] which equals -7.

Step-by-step explanation:

We need to find how long it takes to walk 600 meters. We can do that by 1800/3 and 30/3 which comes out to 10 minutes every 600 meters. We can then just multiply 600*5 and 10*5 which gives us 3000 meters takes 50 minutes.

Answer:

$31.00

Step-by-step explanation:

Given:

We need to find the LCM of 6 and 10:

Multiples of 6:  6, 12, 18, 24, 30

Multiples of 10: 10, 20, 30

Therefore, the LCM = 30

So the least number of notebooks and pencils the teacher can buy to have the same numbers of each is 30.

⇒ 30 ÷ 6 = 5 packages of notebooks

⇒ 30 ÷ 10 = 3 packages of pencils

5 packages of notebooks = 5 × $5.00 = $25.00

3 packages of pencils = 3 × $2.00 = $6.00

Therefore, the least amount of money the teacher can spend to have the same number of notebooks and pencils (30 each) is:

⇒  $25.00 + $6.00 = $31.00

The least amount of money the teacher can spend to have the same number of notebooks and pencils is $31.00.

To find the least amount of money the teacher can spend and have the same number of notebooks and pencils, we need to determine the least common multiple (LCM) of the quantities in the packages.

Notebooks come in packages of 6, and pencils come in packages of 10. The LCM of 6 and 10 is 30.

To achieve the same number of notebooks and pencils, the teacher could buy:

5 notebook packages (5 * 6 = 30 notebooks)

3 pencil packages (3 * 10 = 30 pencils)

Now, let's calculate the cost:

Cost of notebook packages = 5 * $5.00 = $25.00

Cost of pencil packages = 3 * $2.00 = $6.00

Total cost = $25.00 + $6.00 = $31.00

So, the least amount of money the teacher can spend to have the same number of notebooks and pencils is $31.00.

===========================================================

Explanation:

The problem mentions "see the figure" but the figure above the text does not match the problem itself. I'm assuming the figure is shown below the given text, which unfortunately, is cut off from the screenshot.

The good news is that I think I can recreate what's being described. See the image below.

The things to focus on are the left-most and right-most triangles. We'll use the tangent ratio to help determine x and y. Afterward, compute x+y to get the total distance between the buildings.

First we have,

tan(angle) = opposite/adjacent

tan(32) = 500/x

x*tan(32) = 500

x = 500/tan(32)

x = 800.1673

Using similar steps, you should find that,

y = 500/tan(23)

y = 1177.9262

Therefore,

x+y = 800.1673+1177.9262

x+y = 1978.0935 feet is the approximate distance between Soldier Field and Adler Planetarium.

This is of course assuming that the diagram shown below matches with what your textbook has. Round the answer however you need.

Using the binomial distribution, it is found that the probabilities are given by:

a) 0.8681 = 86.81%.

b) 0.1319 = 13.19%.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem, we have that:

Item a:

The probability is P(X = 7), hence:

P(X = 7) = 0.98^7 = 0.8681 = 86.81%.

Item b:

The probability is:

P(X < 7) = 1 - P(X = 7) = 1 - 0.8681 = 0.1319 = 13.19%.

[tex]6r[/tex]

Step-by-step explanation:

let [tex]d[/tex] be the cost of a drink

let [tex]b[/tex] be the cost of a bag of potato chips

and let [tex]r[/tex] be the cost of a ring

[tex]7d[/tex] is the cost of seven drinks

[tex]6b[/tex] is the cost of 6 bags of potato chips

so we add them together to get [tex]7d+6b[/tex]

[tex]3r[/tex] is the cost of three rings

[tex]2(3r)[/tex] is the cost of three rings but doubled

we can expand this to [tex]6r[/tex] which is the cost of 6 rings (or the cost of two rings but doubled)
