What fraction of students are boys if 5 of the 8 students are boys

Answer:

Jennifer should expect a number less than 3 23 times

Step-by-step explanation:

The probability of rolling a number less than 3 on a number cube is 2/6. .

The probability of rolling a number less than 3 on a number cube is 2/6

= 1/3

Jennifer rolls a number cube 69 times

Expectations= probability*total outcome

Expectations= 1/3 * 69

Expectations= 69/3

Expectations= 23 times

Answer: 5/6

Step-by-step explanation:

p - 1/6 = 2/3

    +1/6   +1/6

p = 5/6

Answer:

p = 5/6

Step-by-step explanation:

For this problem, simply take the words of the problem and convert them into an equation as such:

The difference of p and one-sixth implies --> p - 1/6

is two-thirds implies --> 2/3

So, our equation:

p - 1/6 = 2/3

Now simply solve for p, and combine the fractions.

p - 1/6 = 2/3

p - 1/6 + 1/6 = 2/3 + 1/6

p = 2/3 + 1/6

p = 4/6 + 1/6

p = 5/6

Cheers.

Answer:

(4x)¯² (4x)³ (4x)⁹ = (4x)¹⁰

Step-by-step explanation:

(4x)¯² (4x)³ (4x)⁹

The above expression can be simplified as follow:

Recall:

When we have two or more index number with same base and a multiplication sign in between them, we easily simply by adding the index number together while keeping the base constant. This is illustrated below:

a^m x a^n = a^(m + n)

Therefore,

(4x)¯² (4x)³ (4x)⁹ = (4x)^(-2 + 3 +9)

(4x)¯² (4x)³ (4x)⁹ = (4x)¹⁰

Answer:

Step-by-step explanation:

Given the function  j(x) = 11.6[tex]e^x[/tex] and k(x) = [tex]ln \dfrac{x}{11.6}[/tex], to show that both equality functions are true, all we need to show is that both  j(k(x)) and k(j(x)) equal x,

For j(k(x));

j(k(x)) = j[(ln x/11.6)]

j[(ln (x/11.6)] = 11.6e^{ln (x/11.6)}

j[(ln x/11.6)] = 11.6(x/11.6) (exponential function will cancel out the natural logarithm)

j[(ln x/11.6)] = 11.6 * x/11.6

j[(ln x/11.6)] = x

Hence j[k(x)] = x

Similarly for k[j(x)];

k[j(x)] = k[11.6e^x]

k[11.6e^x] = ln (11.6e^x/11.6)

k[11.6e^x]  = ln(e^x)

exponential function will cancel out the natural logarithm leaving x

k[11.6e^x]  = x

Hence k[j(x)] = x

From the calculations above, it can be seen that j[k(x)] =  k[j(x)]  = x, this shows that the functions j(x) = 11.6[tex]e^x[/tex] and k(x) = [tex]ln \dfrac{x}{11.6}[/tex] are inverse functions.

Answer:

1) V = 12 π  ㏑ 3

2) [tex]\mathbf{V = \dfrac{328 \pi}{9}}[/tex]

Step-by-step explanation:

Given that:

the graphs of the equations about each given line is:

[tex]y = \dfrac{6}{x^2}, y =0 , x=1 , x=3[/tex]

Using Shell method to determine the required volume,

where;

shell radius = x;   &

height of the shell = [tex]\dfrac{6}{x^2}[/tex]

∴

Volume V = [tex]\int ^b_{x-1} \ 2 \pi ( x) ( \dfrac{6}{x^2}) \ dx[/tex]

[tex]V = \int ^3_{x-1} \ 2 \pi ( x) ( \dfrac{6}{x^2}) \ dx[/tex]

[tex]V = 12 \pi \int ^3_{x-1} \dfrac{1}{x} \ dx[/tex]

[tex]V = 12 \pi ( In \ x ) ^3_{x-1}[/tex]

V = 12 π ( ㏑ 3 - ㏑ 1)

V = 12 π ( ㏑ 3 - 0)

V = 12 π  ㏑ 3

2) Find the line y=6

Using the disk method here;

where,

Inner radius [tex]r(x) = 6 - \dfrac{6}{x^2}[/tex]

outer radius R(x) = 6

Thus, the volume of the solid is as follows:

[tex]V = \int ^3_{x-1} \begin {bmatrix} \pi (6)^2 - \pi ( 6 - \dfrac{6}{x^2})^2 \end {bmatrix} \ dx[/tex]

[tex]V = \pi (6)^2 \int ^3_{x-1} \begin {bmatrix} 1 - \pi ( 1 - \dfrac{1}{x^2})^2 \end {bmatrix} \ dx[/tex]

[tex]V = 36 \pi \int ^3_{x-1} \begin {bmatrix} 1 - ( 1 + \dfrac{1}{x^4}- \dfrac{2}{x^2}) \end {bmatrix} \ dx[/tex]

[tex]V = 36 \pi \int ^3_{x-1} \begin {bmatrix} - \dfrac{1}{x^4}+ \dfrac{2}{x^2} \end {bmatrix} \ dx[/tex]

[tex]V = 36 \pi \int ^3_{x-1} \begin {bmatrix} {-x^{-4}}+ 2x^{-2} \end {bmatrix} \ dx[/tex]

Recall that:

[tex]\int x^n dx = \dfrac{x^n +1}{n+1}[/tex]

Then:

[tex]V = 36 \pi ( -\dfrac{x^{-3}}{-3}+ \dfrac{2x^{-1}}{-1})^3_{x-1}[/tex]

[tex]V = 36 \pi ( \dfrac{1}{3x^3}- \dfrac{2}{x})^3_{x-1}[/tex]

[tex]V = 36 \pi \begin {bmatrix} ( \dfrac{1}{3(3)^3}- \dfrac{2}{3}) - ( \dfrac{1}{3(1)^3}- \dfrac{2}{1}) \end {bmatrix}[/tex]

[tex]V = 36 \pi (\dfrac{82}{81})[/tex]

[tex]\mathbf{V = \dfrac{328 \pi}{9}}[/tex]

Answer:

(x - 3)(x + 7)

Step-by-step explanation:

x^2 + 4x - 21

=> x^2 + 7x - 3x - 21

=> x(x + 7) -3(x + 7)

=> (x + 7)(x - 3)

Answer:

[tex](x+7)(x-3)[/tex]

Step-by-step explanation:

So we want to factor the expression:

[tex]x^2+4x-21[/tex]

When factoring, we want to find two numbers that equals (a)(c) and add up to b. We can then substitute it for b.

So, we want two numbers that when multiplied equals (1)(-21)=-21 and adds up to 4.

We can use 7 and -3.

So:

[tex]x^2+4x-21\\=x^2-3x+7x-21[/tex]

Factor out an x from the first two terms, and a 7 from the third and fourth terms:

[tex]=x(x+3)+7(x-3)[/tex]

Grouping:

[tex]=(x+7)(x-3)[/tex]

And we are done :)

Answer: x=20.5

Step-by-step explanation:

Given

4x-17=65

Add 17 on both sides (addition property of equality)

4x-17+17=65+17

4x=82

Divide 4 on both sides (division property of equality)

4/4x=82/4

x=20.5

Hope this helps!! :)

Please let me know if you have any question

Answer:

x = 20.5

Step-by-step explanation:

4x - 17 = 65

4x = 65 + 17

x = 82 ÷ 4

x = 20.5

Answer:

1) ASA

2) SSA

Step-by-step explanation:

The sine rule is used when we have; ASA, AAS or SSA cases. However, SSA is an ambiguous case which occurs when there are two sides and a given angle opposite one of these given sides. The triangles resulting from a situation like this requires a much closer look in comparison to SSS, ASA, and AAS cases. SSA may result in one triangle, two triangles, or even no triangle at all.

Answer:

Let the cost the number of cartridges be x.

We have given that cost of one cartridge is 14 $/cartridge.

And we have 168 $ with us.

So, according to question we have an equation-

14x=168

x=168/14

x=12

Hence, we can buy 12 cartridges if we 168 $ and the cost of one cartridge is 14 $.

Answer:

34,466 children

Step-by-step explanation:

Given the following :

Total number of males born in year 2000= 2,086,814

Percentage number of Jacob's born in year 2000 = 1.6516%

The Jacobs make up 1.6516% of all males born that year?.

The number of Jacob's born in year 2000 will be :

1.6516% of the total number of children born in the year 2000

(1.6516 / 100) × 2,086,814

0.016516 × 2,086,814

= 34465.820024

= about 34,466 children

Answer:

3kg = 3000 gm

Step-by-step explanation:

we use this formula

m1x (distance of m1 )= m2 x( distance of m2)

* the distance far from the triangle*

m1 =6 kg

d1 = 3m

m2 = ê (kg )

d2 = 600 cm = 6 m

m1 d1 = m2 d2

6 x 3 = ê 6

ê = 3 kg

mass = 3kg = 3000 gram

#

To make the scale balance, the weight must be added is 3000g.

"A balanced equation is an equation where both sides are equal to the same amount. The answer to the expression on the left side of the equals sign (=) should be equal to the value on the right side of the equals sign".

For the given situation,

From the diagram shown, the distance on both sides of the fulcrum (the triangle) must be the same to make the scale balance.

We know that

1 kg = 1000 g

1 m = 100 cm

Let the unknown quantity be 'x'

To write a balanced equation, units should be the same on both sides.

6 kg = 6000 g

3 m = 300 cm.

The equation is represented as

[tex]6000[/tex] × [tex]300 = x[/tex] × [tex]600[/tex]

⇒ [tex]x = \frac{(6000)(300)}{600}[/tex]

⇒ [tex]x=3000[/tex]

Hence we can conclude that to make the scale balance, the weight must be added is 3000g.

We need to find the less cash received.

A deposit slip is a bank form where the customer fills in the required date such as the date, the depositor's name, the depositor's account number, and the deposit amounts.

Find the subtotal.

= Cash included coins + check 1 + check 2 + check 3

Find the less cash received.

We have,

Total = 62.23

Total = Subtotal - less cash received

62.23 = 151.02 - less cash received

less cash received:
