Answer:

C

Step-by-step explanation:

If I am understanding the question, it is just asking what the possible choices are, and how many of each.

Answer:

x=4/3

Step-by-step explanation:

9x+8=12x+4

Subtract 8 from both sides;

9x+8-8=12x+4-8

Simplify;

9x=12x-4

Subtract 12x from both sides;

9x-12x=12x-4-12x

Simplify;

-3x=-4

Divide both sides by -3

-3x/-3=-4/-3

Simplify;

x=4/3

Answer:

5.   8.49

6.   8.6

7.   B. Joe is taller than the tepee

Step-by-step explanation:

5 - formula for diagonal [tex]d= \sqrt{2} *s[/tex]   s= side length

So 1.4 times 6 = 8.49

6 - Pythagorean Theorem [tex]c= \sqrt{ a2+b2}[/tex]

So [tex]c= \sqrt{ 5 *2+7*2 }[/tex]   c = 8.6

7 -  Formula for height  [tex]h= \sqrt{ l^{2} - r^{2}[/tex]  l=slant height

So [tex]\sqrt{ 7^{2} - 4^{2}} =h\\\sqrt{ 49-16} = h\\h = 5.74\\5.74 < 6[/tex]That means Joe is taller

Answer:

The answers to your questions are :

5. Area of square = 36 , so (4 × X =36) . X=9

The formula used to find diagonal length = side × Rad2

9 × rad2 = 12.72

6 . Rad ( 25+49) = Rad(74) = 8.6

7. B is correct . He is taller than it .

Rad ( Slant height^2 - radius^2 ) = hight

hight = 5.7 .

Answer:

Step-by-step explanation:

Probability of finding 2 left handed students out of 8 samples is 0.1488 or 14.88%.

Binomial distribution is the distribution of a random variable X for which there are only two possibilities. The probability p for the success and the probability of 1-p for the failure, which consist of n trials.

Given,

Number of students in the college = 800

10% of which are left handed.

Probability of finding left handed student = 10% = 0.1

p = 0.1

q = 1 - 01 = 0.9

Number of samples, n = 8

We have to find P(x = 2)

The formula to calculate binomial distribution is,

P(x) = ⁿCₓ pˣ qⁿ⁻ˣ

P(x = 2) = ⁸C₂(0.1)²(0.9)⁶

            = 28 × (0.1)²(0.9)⁶

            = 0.14880348

            ≈ 0.1488

Hence the probability is 0.1488.

Area = 170.2 M2

Area of rectangle = l *b

let l= 3.7m

170.2 = 3.7* b

b= 46m

now , perimeter = 2(l+b)

= 2( 3.7 + 46)

= 99.4 m

Given:

x is directly proportional to y and inversely proportional to z.

x= 15 when y = 10 and z= 4.

To find:

The equation that connecting x, y and z.​

Solution:

It is given that, x is directly proportional to y and inversely proportional to z.

[tex]x\propto \dfrac{y}{z}[/tex]

[tex]x=\dfrac{ky}{z}[/tex]              ...(i)

Where, k is the constant of proportionality.

We have, x= 15 when y = 10 and z= 4.

[tex]15=\dfrac{k(10)}{4}[/tex]

[tex]15\times 4=10k[/tex]

[tex]60=10k[/tex]

Divide both sides by 10.

[tex]\dfrac{60}{10}=k[/tex]

[tex]6=k[/tex]

Putting k=6 in (i), we get

[tex]x=\dfrac{6y}{z}[/tex]

Therefore, the required equation is [tex]x=\dfrac{6y}{z}[/tex].

Answer:

1.1.1) -61

1.1.2) Term 42

Step-by-step explanation:

Tn= dn (difference) + t0 (term 0)

Tn= -4n+ 11

You can now take this general rule to find out the other terms.

Tn= -4(18)+11

Tn= -61

And the term -157

Tn= -4n+11

-157= -4n + 11

-157 - 11= - 4n

-168= -4n

-168/-4= n

42= n
