Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The mean is
The standard deviation is
The random number
Given that the time taken is normally distributed the probability is mathematically represented as
Generally the z-score for the normally distributed data set is mathematically represented as
So
This value is obtained from the z-table
The value is 34/628 and also you needa draw
Answer:
sorry but I don't know the answer
Given:
ABCD is a quadrilateral inscribed in a circle.
m∠A = (2x + 38)°, m∠B = 3x° and m∠D = (x + 20)°
To find:
Measure of angle C
Solution:
<em>In cylic quadrilateral, sum of the measures of opposite angles are 180°.</em>
m∠B + m∠D = 180°
3x° + x° + 20° = 180°
4x° + 20° = 180°
Subtract 20° from both sides.
4x° + 20° - 20° = 180° - 20°
4x° = 160°
Divide by 4 on both sides, we get
x° = 40°
<em>In cylic quadrilateral, sum of the measures of opposite angles are 180°.</em>
m∠A + m∠C = 180°
2x° + 38° + m∠C = 180°
2(40)° + 38° + m∠C = 180°
80° + 38° + m∠C = 180°
118° + m∠C = 180°
Subtract 118° from both sides, we get
m∠C = 62°
The measure of angle C is 62°.
