Answer:
-19
Step-by-step explanation:
~ Distribute:
- 11 = 1 / 2 x + -3 / 2
~ Flip the equation:
1 / 2 x + -3 / 2 = -11
~ Use transposition method:
(take -3 / 2 to the other side)
1 / 2 x = -11 - (-3 / 2)
= -19 / 2
x = -12 / 2 * 2
= -19

Answer: option 1 is the correct answer
Step-by-step explanation:
Number of times for which the die was rolled is 360. It means that our sample size, n is 360.
The probability of rolling a 5 or a 6 is 1/3. It means that probability of success,p = 1/3. The probability of failure,q is
1 - probability of success. It becomes
1 - 1/3 = 2/3
The formula for standard deviation is expressed as
√npq. Therefore
Standard deviation = √360 × 1/3 × 2/3
= √80 = 8.9443
Standard deviation is approximately 8.9
Answer:
65 square units
Step-by-step explanation:
The base of the pyramid is 5 by 5 , surface area is 25 square units.
the side of each one is 4 units "high" and 5 long at the base and to find the are of a triangle you multiple base times height then dived by 2. Therefore each side of the triangle is 10 units square. You have 4 sides so...
40 (total of all the sides ) +25 ( base ) = 65
Hello!
To find the interquartile range, subtract the value of the upper quartile from the value of the lower quartile.
33 - 25 = 8
The interquartile range is 8. Hope I helped! :3
