A mixture of nuts contains 2 kg of cashew nuts and
600 grams of peanuts. What is the ratio of peanuts to cashew nuts in the mixture?​

Answers

Answer 1

Answer:

3 : 10

Step-by-step explanation:

2 kg = 2000g

600g peanuts : 2000 cashew nuts

600 : 2000

divide both sides by a common divisor ( 200)

600/200 : 2000/200

3 : 10

Assume the random variable X is normally distributed with mean = 50 and standard deviation = 7. Compute the probability, P(X > 35). Be sure to draw a normal curve with the area corresponding to the probability shaded.

Answers

Answer:

P [ X > 35 ]  =  0,983         or    P [ X > 35 ]  = 98,3 %

Step-by-step explanation:  See Annex valid region for 98,3 in red lines

P [ X > 35 ]  =  1  - P [ X ≤ 35 ]

P[ X ≤ z  ]  = ( X -  μ₀ ) / σ

P [ X ≤ 35 ] =  ( 35  -  50  ) / 7

P [ X ≤ 35 ] =  - 15 / 7

P [ X ≤ 35 ] = - 2,1428

We find for  z(score)  =  - 2,14  in z-table the value of  0,01618

P [ X ≤ 35 ] =  0,01618        or     P [ X ≤ 35 ] ≈ 1,62 %

And  

P [ X > 35 ]  = 1  - 0,01618

P [ X > 35 ]  =  0,983         or    P [ X > 35 ]  = 98,3 %

Which of the following is equivalent to x^-1/2

1) -1/2x
2) -√x
3) 1/√x
4) -1/2x

Answers

Answer:

Option (3) is correct.

Step-by-step explanation:

We need to find the expression that is equivalent to [tex]x^{-1/2}[/tex].

The property is : [tex]x^{-a}=\dfrac{1}{x^a}[/tex]

Here, a = 1/2

So,

[tex]x^{-1/2}=\dfrac{1}{x^{1/2}}[/tex]

We know that, [tex]x^{1/2}=\sqrt{x}[/tex]

[tex]\dfrac{1}{x^{1/2}}=\dfrac{1}{\sqrt{x} }[/tex]

So, [tex]x^{-1/2}[/tex] is equivalent to [tex]\dfrac{1}{\sqrt{x} }[/tex]

Hence, the correct option is (3).

[tex] \frac{x}{11} - 3 = - 16[/tex]
Whoever answers first gets brainlest ​

Answers

Answer:

x= - 143

Step-by-step explanation:

x/11 -3 = -16

transpose the -3 first

x/11= -16+3

x/11= -13

transpose the 11

x= -13×11

x= - 143

Answer: x=-143

Why:
Since we are given the function/equation of (x/11)-3=-16, we must use reverse operations in order to solve for the value of x.

First, we must first ADD 3 to both sides in order to begin our isolation of the x variable. This cancels out the -3 on the left side and adds 3 to the right side. Since we already have -16, adding 3 will give us -13. Now we have the equation of (x/11)=-13.

And now, in order to get rid of the 11, we must do the opposite of diving (since we see the x is being divided by 11). So by MULTIPLYING by 11 on both sides, we have now canceled out the 11 on the left side and multiplied the -13 on the right side by 11. Given that -13 times 11 equals -143, this will give you the final result of x=-143.

2(x+3)+3x-10=
Answer please

Answers

Answer:

Simplifying

2(x + 3) + 3x + -10 = 0

Reorder the terms:

2(3 + x) + 3x + -10 = 0

(3 * 2 + x * 2) + 3x + -10 = 0

(6 + 2x) + 3x + -10 = 0

Reorder the terms:

6 + -10 + 2x + 3x = 0

Combine like terms: 6 + -10 = -4

-4 + 2x + 3x = 0

Combine like terms: 2x + 3x = 5x

-4 + 5x = 0

Solving

-4 + 5x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 5x = 0 + 4

Combine like terms: -4 + 4 = 0

0 + 5x = 0 + 4

5x = 0 + 4

Combine like terms: 0 + 4 = 4

5x = 4

Divide each side by '5'.

x = 0.8

x = 0.8
