Answer:
27.756
Step-by-step explanation:
1) Move all the decimal points to the right and do the multiplication
18 * 1524 = 27756
1.8 to 19 = one move
15.42 to 1542 = two moves
total three decimal point shifts
2) count the number (total) that you moved the decimal points
3) starting from the right move the decimal point that many times to the LEFT in for the answer
27.756
Answer:
<u>k = 1.5</u>
Step-by-step explanation:
To find the value of k, at first we will find the point of intersection of the lines
y =2x –5 and y = –x+1
Solve the equations to together by equating the values of y
So, 2x - 5 = -x + 1
Solve for x
3x = 6 ⇒ x = 6/3 = 2
So, y = -x + 1 = -2 + 1 = -1
So, the point of intersection of the lines ⇒ (2,-1)
line y = kx –4 pass through the point of intersection of the lines
so, line y = kx –4 pass through the point (2,-1)
So, at x = 2 , y = -1
∴ -1 = 2k - 4
Solve for k
-1 + 4 = 2k
2k = 3
k = 3/2 = 1.5
<u>So, the value of k is 1.5</u>
Answer:
c. 52 rad/s
Step-by-step explanation:
Final question does not correspond with available option. The real question is: <em>What is the angular speed in radians per second?</em>
At first we assume that spin balance rotates at constant rate and convert given angular speed, measured in revolutions per minute, into radians per second:
Which corresponds to option C.
Answer:
The Probability that Event A and Event D occur is equal to the probability Event A occurs times the probability that Event D occurs, given that A has occurred.
We can find the values of 
and 
using the above form formula.
;
From the given table, we have the values of P(A), P(D), 
and 
.
Since, Probability=
∴
, 
, 
and 
Now, putting these values in above formula we get,
.
As, you can see above that the values of P(A|D) and P(D|A) are not equal.
