Answer:
y = 6.5
Step-by-step explanation:
Using a ratio
10 13
----- = -----------
10+5 13+y
10 13
----- = -----------
15 13+y
Using cross products
10(13+y) = 13*15
10(13+y) = 195
130+10y = 195
Subtract 130 from each side
10y = 65
Divide by 10
y = 65/10
y = 6.5
Answer:
3620.57
Step-by-step explanation:
Given: Stacy hits the jackpot one day at the gumball machine and won 4 gumballs, radius of each gumball is 6 mm
To find: Total volume of all 4 gumballs
Solution:
Gumball is Spherical
Volume of Sphere = (4/3)πr³
r = Radius of Sphere
r = 6mm
Volume of 1 gumball = (4/3)π * 6³
= 288π mm³
Volume of 4 gumballs = 4 * 288π
= 1152π mm³
using π = 22/7
= 3,620.57 mm³
or using π = 3.14
= 3,617.28 mm³
Volume of 4 gumballs = 288π mm³ ≈ 3,620 mm³
X would be 90° ... every x is 90°
The points which satisfy the inequalities in discuss are; Choices D (7,10) and F(8,17).
<h3>Which points omg the answer choices satisfy the system of inequalities?</h3>
It follows from the inequality; x > 5.
Also, substituting 5 for x in; y < 2(x); we have;
y < 10.
Hence, the points which satisfy the inequalities are; (8,17) and (7,10).

Answer: (A) randomly selected elements within each of the strata form the sample.
Step-by-step explanation:
Stratified random sampling is a random sampling technique in statistics .
- It includes the partition of the entire population into sub-parts called strata.
- The strata are formed on the basis of the characteristics shared by members .
- After the formation of strata, researcher randomly selects participants from each strata to ensure that that the participant of every group must involve in the sample to represent each character.
Hence, the correct answer is :
(A) randomly selected elements within each of the strata form the sample.
