Answer:
D. $120
Explanation:
P= principal amount, which is $2000 in this case
R= interest rate. In this case, it's 3% per year (or 0.03 in decimal form)
T= time, which in this case is 2.
To find the simple interest, we multiply 2000 × 0.03 × 2 to get 120.
I hope this helped! :)
Answer:
0.75
Step-by-step explanation:
Z-score tells the no. of standard deviations a data point is from the mean.
the formula for z score is given by
z-score= (data value - mean) / standard deviation
Given:
mean=44
standard deviation= 8
data point=50
putting the values of mean(44), standard deviation(8) and given data value(50) in the above equation
z-score= (50-44)/8
= 6/8
=0.75 !
Answer:
7/24
Step-by-step explanation:
7/8 x 1/3= 7x1=7; 8x3=24
Answer:
Given the statement: Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P.
Properties of Kite:
- The diagonals are perpendicular
- Two disjoint pairs of consecutive sides are congruent by definition of kite
- One diagonal is the perpendicular bisector to the other diagonal.
It is given that: Side QR = 5m and diagonal QS = 6m.
Then, by properties of kite:

Substitute the value of QS we get QP;
= 3 m
Now, in right angle 
Using Pythagoras theorem:

Substitute the given values we get;

or

Subtract 9 from both sides we get;

Simplify:

Therefore, the length of segment RP is, 4m
The answer is 12x^3-4×^2-4
