Step-by-step explanation:

Hence, if his parents giving him $\(35\) per week then he can purchase his game system.

What is the simplification?

Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

Here given that,

Joe has $\(180\) in his bank account he wants to buy a new gaming system for $\(250\) in two weeks his parents have offered to lend him money if he needs it he gets $\(20\) a week for a allowance

So,

His account saving is $\(180\).

He wants to purchase a game system which costs $\(250\).

His parents giving $\(20\) per week. So iin two weeks it is \(20(2)=40\)$.

Then , the total savings he had \(180+40=220\)$

So he needs \(30\)$ more to purchas his game system

If his parents giving him $\(35\) per week then in two weeks it would be \(35(2)=70\)$.

Then his total savings are

\(180+70=250\)$.

Hence, if his parents giving him $\(35\) per week then he can purchase his game system.

The probability that a subject would guess more than 20 correct in a series of 36 trials is 0.0001

In a series of 36 trials, if the subject is guessing randomly, then the probability of correctly guessing odd or even is 1/2.

Let X be the number of correct guesses in a series of 36 trials. X follows a binomial distribution with parameters n = 36 and p = 1/2.

The probability of guessing more than 20 correct is:

P(X > 20) = 1 - P(X ≤ 20)

Using a binomial distribution table, we can find that P(X ≤ 20) = 0.9999 (rounded to four decimal places).

Therefore: P(X > 20) = 1 - 0.9999 = 0.0001

So the probability that a subject would guess more than 20 correct in a series of 36 trials is 0.0001 (rounded to four decimal places).

The body surface area is given by the equation A = 1.6865 m²

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the body surface area be represented as A

Now , the equation will be

A = ( HW / 3600 )^1/2

A = √( HW / 3600 )   be equation (1)

where H is the height in centimeters and W is the weight in kilograms

Now , the value of H = 160 cm

The value of W = 64 kg

Substituting the values in the equation , we get

A = √ [ ( 160 x 64 ) / 3600 ]

On simplifying the equation , we get

A = √ ( 10240/3600 )

A = √ ( 2.8444 )

A = 1.6865 m²

Therefore , the body surface area is 1.6865 m²

Hence , the equation is A = 1.6865 m²

Answer:

x = 12

Step-by-step explanation:

we can put this is a proportion: (new side 1) / (old side 1) = (new side 2) / (old side 2)

so in this case, 18 would be old side 1, x would be new side 1

12 would be old side 2, and 8 would be new side 2

plug these in: x/18 = 8/12

cross multiply 18 and 8: x = 144/12

now simplify: x = 12

2/3 = 8/12

7/12 = 7/12

3/4 = 9/12

7/12 < 8/12 < 9/12

So, 7/12 < 2/3 < 3/4

Step-by-step explanation:

The numbers representing the first 5 members selected is option A. 24, 07, 59, 62, 20.

A random number table is a table of digits which are used to select random samples.

The random number table can be used as described below.

Given population size is 78 out of which 10 members has to be selected.

Each member has been numbered from 01 to 78.

The given line from a random number table is,

24000  75983  62200  91518  11198  88936

We have to select the first 5 members.

Select consecutive two digits in order since the number we assigned consists of two digits.

Select two digits from the first. It is 24.

First member selected is one with number 24 assigned.

Next two digits are 00. Since there are no member with 00 as the number assigned, skip it.

Next two digits are 07. Select it.

Next two digits are 59. Select it

Next two digits are 83, which is not included in the set 01 to 78. Skip it.

Next two digits are 62. Select it.

Next two digits are 20. Select it.

So the selected members are 24, 07, 59, 62, 20.

Hence the selected members using the random number table are 24, 07, 59, 62, 20.

The difference between the amount purchased and amount used  is 3.75 tons.

The amount of sand the company have left is calculated as follows;

The total amount purchased = 13 1/4 tons

The amount of sand used = 9 1/2 tons

To find the difference between the amount purchased and amount used we will convert the mixed fraction into improper fraction as follows;

13 1/4 tons = 53/4 laps = 13.25 tons

9 1/2 tons = 19/2 tons = 9.5 tons

The difference between the amount purchased and amount used is;

= 13.25 tons - 9.5 tons

= 3.75 tons = 3 3/4 tons

Answer:

m=200

Step-by-step explanation:

percent means 100,so we duvude 300:by 100 then m=200

The simplified expression can be written as:

\((-\sqrt{6} )*(-2*\sqrt{-42} ) = \sqrt{-1,008}\)

Here you need to remember the property:

\(\sqrt{x} *\sqrt{y} = \sqrt{x*y}\)

Now we have the expression:

\((-\sqrt{6} )*(-2*\sqrt{-42} )\)

First, we can cancel the two first negative signs to get:

\((\sqrt{6} )*(2*\sqrt{-42} )\)

Now we can write the 2 as the square root of 4.

\((\sqrt{6} )*(\sqrt{4} *\sqrt{-42} )\)

Finally, we can use the above property to get:

\((\sqrt{6} )*(\sqrt{4} *\sqrt{-42} ) = \sqrt{6*4*(-42)} = \sqrt{-1,008}\)
