Answer:
Interest = $1.75
Step-by-step explanation:
Maria invest $600, and receives interest of $30 per year
We know that PRT/100= INTEREST
R=( 100*INTEREST)/(PT)
R = (100*30)/(600*1)
R= 3000/600
R= 5%
Jane invest $350 at Sam rate with Maria , that is 5% , for a year, her interest
Interest= 350*5*1/100
Interest = $1.75
Geometric sequence is a sequence of numbers that have a common ratio between them.
D. 8 mm by 10 mm by 4 mm
20 mm by 8 mm by 2 mm
8 x 10 x 4 = 320 mm
20 x 8 x 2 = 320 mm
Since the interior is 168 then the exterior is 180-168 leaving 12. is a total of 360 degrees so 360/12= 30 or 30 sides.
<span>Population mean (u) = $131.80
Standard deviation (sd) = $29.12
Sample number (n) = 15
Sample mean = $150
Using Z score formula..
Z = (150 - 131.80)/ (29.12)/15^1/2
Z = 2.420
Area under the curve (alpha) with Z = 2.420 = 49.22
In percentage Alpha = 0.4922
Probability = 1-Alpha
Probability = 1- 0.4922 = 0.5078</span>
