\huge\boxed{Hi,\:hope\:you\:are\:having\:a\:splendiferous\:day!}The digit that makes this statement true is 4.

Here's a trick to check if the number is divisible by 9.

We add all the digits together, and if the final result is 9, then the number is

\huge\bold{divisible\:by\:9}.

If we plug in the digit 1, the final result won't be 9.

Same with 2, 3, 5, 6, 7, 8, 9 and 0.

Let's check 4:

7+7+8+1+4+5+4=14+9+9+4=14+18+4=14+22=36

3+6=9

\huge\boxed{Therefore, this\:number\:is\:divisible\:by\:9.}\\\huge\sf{Good\:luck!}\\\huge\underlined{Hope\:it\:helps!}\\\\{FelicitousTeen\:here\:to\:help}

Sunny_sXe [5.5K]

Answer:

Z = (60 - x + y + z) / √a + b + c

Step-by-step explanation:

Since it is a normal distribution, we must calculate the mean and standard deviation, since we do not have data, what we will do is leave them based on these:

Thus Total Mean time = M1 + M2 + M3

given:

M1 = x

M2 = y

M3 = z

Total Mean Time M = x + y + z

Now to calculate the standard deviation we first calculate the variance.

The total Variance V = V1 + V2 + V3

Given:

V1 = a

V2 = b

V3 = c

V = a + b + c

Thus Standard deviation SD of the complete operation is

SD = √ V

SD = √a + b + c

we need to find the probability that the mean time is less than or equal to 60 minutes, the first thing is to find the value of Z.

Formula of Z is:

Z = (X - M) / SD

In this case X = 60.

On plugging the values we get

Z = (60 - x + y + z) / √a + b + c

refer to the Z table and find the Probability of Z ≤ (60 - x + y + z) / √a + b + c

The answer is 130°
Because it is a circle, the angles have to all add up to 360°. So if you add up the two known angles, and subtract that sum from 360, you will get 130°
