Answer:

(b) y/6 = 7/5.25

Step-by-step explanation:

Clockwise from the obtuse angle, the side ratios are ...

4.2 : 3.15

y : 6

7 : 5.25

6 : x

4 : 3

A true proportion will have corresponding parts of these ratios in corresponding places. The only true proportion listed is ...

$\dfrac{y}{6}=\dfrac{7}{5.25}$

O COUNTING AND PROBABILITY

valina [46]

Answer:

a. $Odds = \frac{3}{7}$

b. $Odds = \frac{7}{3}$

Step-by-step explanation:

Given

$n(Black) = 7$

$n(Grey) = 2$

$n(White) = 1$

$n(Total) = 10$

Solving (a): Odds against winning

Since, the arrow must stop at black, then

The odds against winning is calculated as thus:

$Odds = \frac{n(Total) - n(Black)}{n(Black)}$

$Odds = \frac{10 - 7}{7}$

$Odds = \frac{3}{7}$

Solving (b): Odds in favor of winning

Since, the arrow must stop at black, then

The odds is calculated as thus:

$Odds = \frac{n(Black)}{n(Total) - n(Black)}$

$Odds = \frac{7}{10 - 7}$

$Odds = \frac{7}{3}$

Determine whether the forces are pulling at right angles to each other. Explain. 3.5 lb, 6.2 lb, resultant force 9.1 lb

8_murik_8 [283]

The resultant force in this item, is that which connects the heads of the magnitude of the given vectors. The magnitude of the resultant force can be calculated through the Pythagorean theorem which states that the square of the resultant force should be equal to the sum of the squares of the smaller forces. That is,
A² + B² = C²

Investigating the vector values,
A² + B² = (3.5 lb)² + (6.2 lb)² = 50.69 lb²
C² = (9.1 lb)² = 82.81 lb²

Since the Pythagorean theorem is not satisfied by the given set of forces then, the forces are not in right angle.

The answer to the question is letter C.
