Please help me solve this question

Pie

Answer:

$x=10$

Step-by-step explanation:

The measure of an inscribed angle of a circle is exactly half the measure of the arc it forms.

Therefore, we have the following equation:

$2(3x+25)=5x+60,\\6x+50=5x+60,\\x=\boxed{10}$

A Normal distribution has mean µ = 61.6. Find it’s standard deviation if 20% of the values are greater than 70. (Hint--use the z

statuscvo [17]

Answer:

The value is $\sigma = 9.976$

Step-by-step explanation:

From the question we are told that

The mean is $\mu = 61.6$

Given that 20% of the values are greater than 70, the z-score to the right of the curve corresponding to 20% (0.2) of the values is

$z-score = 0.842$

Generally this z-score is mathematically represented as

$z-score = \frac{x - \mu }{\sigma }$

Here x = 70

$0.842 = \frac{70 - 61.6 }{\sigma }$

=> $\sigma = 9.976$

25% of what number is 19

kkurt [141]

Most of the information's necessary for solving this problem is already given in the question.
Let us assume the number to be = x
Then
25% * x = 19
(25/100) * x = 19
x/4 = 19
x = 19 * 4
= 76
So the unknown number is 76. I hope there is no complexity in the method described above and also the procedure is clear enough for you to understand. You can use this method for solving similar type of problems in future without requiring any additional help from outside.
