These are independent so probability of one does not affect the other.
1. P = 1/8 * 1/6 = 1/48
2. P=1/8 * 3/6 = 3/48 or 1/16
3. P= 4/8 * 1/6 = 4/48 or 1/12
4. P= 4/8 * 3/6 = 12/48 or 1/4
5. P= 5/8 * 2/6 = 10/48 or 5/24
6. P= 4/8 * 2/6 = 8/48 or 1/6

21. Find x, given AD = BC =6 m.

BigorU [14]

Answer:

Draw a perpendicular line from point A to line segment BC. Name the intersection of said line at BC “E.” You now have a right angled triangle AED.

Now, you know AD = 6 m. Next, given that the trapezoid is a normal one, you know that the midpoints of AB and DC coincide. Therefore, you can find the length of DE like so, DE = (20–14)/2 = 3 m.

Next, we will use the cosign trigonometric function. We know, cos() = adjacent / hypotenuse. Hence, cosx = 3/6 = 1/2. Looking it up on a trigonometric table we know, cos(60 degrees) = 1/2. Therefore, x = 60 degrees.

Alternatively, you could simply use the Theorem for normal trapezoids that states that the base angles will be 60 degrees. Hope this helps!

Which place is the tenths and what is it rounded to? please answer quick thx

Lubov Fominskaja [6]

Answer:

Step-by-step explanation:

see attached to identify which is the tenth's place

How you round the tenth's place depends on the digit in the hundredths place.

If the hundredths digit is less than 5, then you keep the tenths place the same (i.e round down)

If the hundredths digit is greater or equal than 5, then you increase the tenths place by 1 (i.e round up)

Rochelle and her father watched a football game on monday night the quarterback threw the all a total of 318 yards how many feet

prohojiy [21]

Answer:

954 feet.

Step-by-step explanation:

We have been given that the quarterback threw the ball a total of 318 yards. We are asked to find the number of feet the quarter back throw the ball.

We know that 1 yard equals to 3 feet.

To convert 318 yards in feet, we will multiply 318 by 3 as:

$318\text{ yards}\times \frac{\text{3 feet}}{\text{Yard}}=318\times\text{3 feet}=954\text{ feet}$

Therefore, the quarter back threw the ball a total of 954 feet.
