Answer:
Here ,
2x-30° +70° +x-10° = 180° ( sum of triangle is 180°)
3x+30 =180°
3x=150°
x=50°
<span>before answering this question, we should know the properties of angles and parallel lines. For example, two angles are called interior alternate angles, if each angle is created by the existence of two parallel lines and a an another line called transversal. As for our case, 3 and 5 are alternate angles, so meas 3 = meas 5. It verifies Z test when we look at the figure.</span>
<span>3x - 5 < 4.
Add 5 to both sides,
3x < 9
Divide 3 from both sides,
x < 3
Hope this helps!</span>
Answer:
Option C.
Step-by-step explanation:
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
Let
x------> size of the event space (total person's hemoglobin level of 9 or above with age above 35 years)
y-----> size of the sample space (total person's age above 35 years)
so
In this problem we have
Complete the table to find the total person's hemoglobin level of 9 or above (person's age above 35)
Let
y------> total person's hemoglobin level between 9 and 11 (person's age above 35)


Find the value of x

substitute the values
Answer:
Mean
Step-by-step explanation:
Adding up and dividing to find the mean.
We simply add up all of the individual grades, get the total, and then divide by the number of students in the class.
