Answer:

Probability = 0.04 (Approx)

Step-by-step explanation:

Given:

High school diploma = 0.03

Total holder = 0.03+0.44+0.26+0.11 = 0.84

Find:

Probability

Computation:

Probability = 0.03 / 0.84

Probability = 0.0357

Probability = 0.04 (Approx)

Answer:

The proportion of acid at 70% that the chemist must use will be 77.8%, while the remaining 22.2% will be acid at 25%.

Step-by-step explanation:

Since the chemist has 100 ml of solution with 25% acid, and wants to obtain a solution of 60% acid by mixing the first with another 70% acid solution, to determine how much of each solution the chemical should use necessary to perform the following calculation:

70 x 1 + 25 x 0 = 70

70 x 0.9 + 25 x 0.1 = 65.5

70 x 0.8 + 25 x 0.2 = 61

70 x 0.7 + 25 x 0.3 = 56.5

Therefore, the proportion to be used is between 70% and 80% of acid at 70%, and 20% to 30% of acid at 25%.

70 x 0.75 + 25 x 0.25 = 58.75

70 x 0.76 + 25 x 0.24 = 59.2

70 x 0.77 + 25 x 0.23 = 59.65

70 x 0.78 + 25 x 0.22 = 60.1

Thus, the proportion should be between 77 and 78% of acid at 70% and 22 and 23% of acid at 25%.

70 x 0.778 + 25 x 0.222 = 60.01

Thus, finally, the proportion of acid at 70% that the chemist must use will be 77.8%, while the remaining 22.2% will be acid at 25%.

Answer:

2.6

Step-by-step explanation:

We have the function  f (x) = [x – 3]

We need to inster the value required which is 5.6

f (5.6) = [5.6 – 3]=

5.6-3 =2.6

f (5.6)=2.6

Hmmmm i think its 5/22

Step-by-step explanation:

So basically how i got it was 2/5*11

And that got me 5/22

I do not think you could simplify this

Either I'm very smooth brain or you can't simplify 5/22

Answer:

1.8 or less

Step-by-step explanation:

girls 1.8 or less

Ricardo’s rate in meters per second is equivalent to 12 meters per second.

        {r} = dy/dx

Given is that Ricardo ran the 60-meter sprint in 5 s.

Ricardo’s rate in meters per second

r = d/t

r = 60/5

r = 12

Therefore, Ricardo’s rate in meters per second is equivalent to 12 meters per second.

Answer:

Step-by-step explanation:

Lets solve the expressions one by one

1. 7-5

we can see that it is simple subtraction. A smaller number is being subtracted from a large number.

So the answer is 2

2. -7+5

There are two numbers with different signs. When there is a number with plus and a number with minus both quantities are subtracted but the larger quantity determines the sign of the answer.

In this case, 7 is larger and has negative sign, the answer will be -2

3. -7-5

When there are two numbers with minus sign they are added but the answer has the minus sign with it.

So the answer will be: -12

4. 7-(-5)

When minus is multiplied with minus it converts to positive

So

[tex]= 7-(-5) = 7+5 = 12[/tex]

Hence,
