Answer: 0.167

Step-by-step explanation:

Given: Total batteries = 10

Batteries that are still working = 6

Number of ways to pick 3 working batteries = [tex]^6C_3=\dfrac{6!}{3!3!}[/tex]

[tex]=\dfrac{6\times5\times4\times3!}{6\times3!}\\\\=20[/tex]

Number of ways of pick 3 batteries out of 10 =

[tex]^{10}C_3=\dfrac{10!}{3!7!}=\dfrac{10\times9\times8\times7!}{6\times7!}\\\\=120[/tex]

Required probability = [tex]\dfrac{20}{120}=0.167[/tex]

Hence, the probability that all of the first 3 she chooses will work = 0.167

i just took the test.

The temperature of City A is 5° C and temperature of City B is 4° C.

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. LHS = RHS is a common mathematical formula.

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:

4x = 8 + 3y.....................(1)

x − 2y = −3.......................(2)

Solving Equation (1) and (2), we get

4x = 8 + 3y

4( -3 + 2y) = 8 + 3y

-12 + 8y = 8 +3y

8y - 3y = 8 + 12

5y = 20

y= 4

and, x = -3 + 2y = -3 +2(4) = -3 + 8 = 5

Hence, the temperature of City A is 5° C and temperature of City B is 4° C.

Step-by-step explanation:

The equations would be:

a+b ≥40 (cupcakes +cookies must be at least 40 total)

5+a≤ b

(At most 5 more cupcakes then cookies)

2.50a+1.50b≤ 105

Answer:

  (x, y) = (-244/29, -80/29)

Step-by-step explanation:

A graph (2nd attachment) shows the solution to be non-integer values, so we'll use the "cross multiply method" to find the solution.

Rewriting the equations to general form gives ....

  2x -9y -8 = 0

  5x -8y +20 = 0

Writing the coefficients in two rows of four, we have the table as in the first attachment. (The first column is repeated as the 4th column.)

Now, the cross product differences are formed. Each "orange" cross product difference is the difference of the product of "blue" coefficients and the product of "yellow" coefficients. The same formula is copied to the right.

These difference numbers go, left to right, into the form ...

  1/p1 = x/p2 = y/p3 . . . . . . where p1, p2, p3 are the cross product differences

In this problem, the solution is ...

  x = -244/29 ≈ -8.414

  y = -80/29 ≈ -2.759

Answer:

240000

Step-by-step explanation:

Answer:

240,000

Step-by-step explanation:

Pretend it is only 4 ten thousands. It would be 40,000. Since it is 24, there are 2.4 times more digits, so it would be 240,000 since it is at least 10 times more than a thousand which would be the 40,000 .

In case anyone needs 24 ten thousandths in the future:

0.0024

0.00024 is equal to 24 hundred-thousandths and there are tenths (0.1), hundredths (0.01), and thousandths (0.001). Then ten thousandths would just be a step lower (0.0001) but since there are 24, it would go into the thousandths place but have the four in the ten thousandths. So it would be 0.0024.

The solution for the value of x by definition of linear pair angle is 21.

Used the concept of linear pair angle that states,

The sum of a linear pair angle in a straight line would be 180 degrees.

Given that the two linear pair angles are,

(3x + 18) and (4x + 15)

Now, the sum of linear pair angles would be 180 degrees.

Hence, it can be written as,

(3x + 18) + (4x + 15) = 180°

Solve for x,

3x + 4x + 18 + 15 = 180°

7x + 33 = 180

Subtract 33 on both sides,

7x = 180 - 33

7x = 147

Divide 7 on both sides,

x = 147/7

Therefore, the value of x is,

x = 21

x = 1.2

Step-by-step explanation:

[tex]\frac{10x-3}{3}[/tex] + [tex]\frac{5x+2}{4}[/tex] = 5

You would want to make the denominators of both fractions the same first. Their lowest common multiple is 12, so we shall make the denominators 12 by multiplying the first fraction by 4 and the second fraction by 3.

[tex]\frac{4(10x-3)}{12}[/tex] + [tex]\frac{3(5x+2)}{12}[/tex] = 5

Simplify.

[tex]\frac{40x-12}{12}[/tex] + [tex]\frac{15x+6}{12}[/tex] = 5

Now we can combine both fractions together since their denominator is the same.

[tex]\frac{40x-12+15x+6}{12}[/tex] = 5

Simplify.

[tex]\frac{55x-6}{12}[/tex] = 5

Isolate 55x-6.

55x-6 = 5 × 12

Simplify.

55x-6 = 60

Isolate the 55x.

55x = 60+6

Simplify.

55x = 66

Find x.

x = [tex]\frac{66}{55}[/tex]

Simplify.

The weather studies fall under atmospheric science.The Christopher and Emma should learn about the local weather and then identify affects on the locality.

Step-by-step explanation:

The weather studies are dynamic. Sometimes weather follows trend but in some cases weather does not follows trend and there is heavy rainfall or snowfall than expected. The forecast of weather is very difficult to be accurate. However near guess can be made about the weather conditions by observing the trends of previous years.

Answer:

x = -7/2

Step-by-step explanation:

½(4x - 8) = 6x + 10

simplify

2x - 4 = 6x + 10

subtract 6x from both sides

-4x - 4 = 10

add 4 to both sides

-4x = 14

divide both sides with -4

x = -14/4

simplify

x = -7/2

Answer:

½(4x - 8) = 6x + 10

4x-8=12x+20

-20-8=12x-4x

-28=8x

Answer:

The length of Big Ben shadow is 252.8 feet

Step-by-step explanation:

The given parameters are;

The height of the Big Ben clocktower in London ≈ 316 feet tall

The length of the shadow Shana casts = 4-foot

The height of Shania = 5 feet

Therefore, we have, by similar triangles;

[tex]\dfrac{The \ length \ of \ the \ shadow \ Shana \ casts }{The \ height \ of \ Shania} = \dfrac{The \ length \ of \ the \ shadow \ The \ Big \ Ben \ casts}{The \ height \ of \ the \ Big \ Ben \ clocktower}[/tex]Substituting the values, gives;

[tex]\dfrac{4 \ feet}{5 \ feet} = \dfrac{The \ length \ of \ the \ shadow \ The \ Big \ Ben \ casts}{316 \ feet}[/tex]

[tex]The \, length \, of \, the \, shadow \, The \, Big \, Ben \ clocktower \ casts = 316 \ feet \times \dfrac{4 \ feet}{5 \ feet} = 252.8 \ feet[/tex]

The length of the shadow The Big Ben clocktower casts = The length of Big Ben shadow = 252.8 feet
