So basically x and y are 4 because the hypotenuse of a 45 45 90 triangle is x square root of four. both legs of the triangle are congruent, given taht it’s a 454590
<h2>Answer:</h2>
5x + 7y = 17 ....(1)
x + 4y = 19 .....(2)
<u>From equation 2</u>
x + 4y = 19
x = 19 - 4y
<u>Putting the value of x in Equation (1)</u>
5(19 - 4y) + 7y = 17
95 - 20y + 7y = 17
- 20y + 7y = 17 - 95
-13y = -78
y = 
y = 6
<u>Now, putting the value of y in equation </u><u>(</u><u>2</u><u>)</u>
x + 4y = 19
x + 4(6) = 19
x + 24 = 19
x = 19 - 24
x = -5
<u>Therefore, the value of y is 6 and value of x is -5</u>

Step-by-step explanation:
Answer:
a. 0.4
b. Not independent.
Step-by-step explanation:
a. We use the probability table attached below for our calculations.
-the probability that an agreement is reached on both sides is obtained from the table:

b. To determine whether the two events are independent, we compare the probabilities
and
where i denotes insurance and s denotes salaries:

Two events are considered to be independent, if and only if:

Hence, the events are not independent.
