By observing the dash marks on each side we know that this is an equalateral triangle, meaning each angle is 60°. If X=32 then we can tell it does by solving this equation 2(32) - 4 =60 because 2(32)=64 and 64 - 4=60°.
Therefore X=32

Answer:

As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.

Step-by-step explanation:

Mean of the batch:

The mean of the batch is the sum of all values divided by the number of items. So

$M = \frac{199+204+201+197+195+204+200}{7} = 200$

Mean in the desired interval.

Standard deviation:

Square root of the sum of the difference squared between each term and the mean, divided by the number of items. So

$S = \sqrt{\frac{(199-200)^2+(204-200)^2+(201-200)^2+(197-200)^2+(195-200)^2+(204-200)^2+(200-200)^2}{7}} = 1.18$

As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.

How long will it take for the money to triple? Compounded continuously.

Artemon [7]

The formula for compounded continuously is :

$A=Pe^{rt}$

Here the Amount triples , so let us say the new amount A=3P

$3P=Pe^{rt}$

Cancelling P from both sides we get,

$3=e^{rt}$

Now here we are given rate is 2.75% or 0.0275,

$3=e^{0.0275t}$

solving for t we get

t=39.95 years
