Answer:
The slope is -1/6
Step-by-step explanation:
Answer:
Step-by-step explanation:
Volume = mass * density
<u>Substitute values and calculate:</u>
- V = 618.7 * 2.7 = 1670.49 mL
8x^3+64y^3
factor out 8
8(x^3+y^3)
this is known as the sum of cubes
8(x + y) (x^2 - x y + y^2)
Answer: 0.5467
Step-by-step explanation:
We assume that the test scores for adults are normally distributed with
Mean :
Standard deviation :
Sample size : = 50
Let x be the random variable that represents the IQ test scores for adults.
Z-score :
For x =85
For x =115
By using standard normal distribution table , the probability the mean of the sample is between 95 and 105 :-
Hence, the probability that a randomly selected adult has an IQ between 85 and 115 =0.5467
Answer:
76 balls and 24 bats
Step-by-step explanation:
Set up a system of equations where x is the number of balls and y is the number of bats:
x + y = 100
4.5x + 20y = 822
Solve by elimination by multiplying the top equation by -20, then combine the equations together:
-20x - 20y = -2000
4.5x + 20y = 822
-15.5x = -1178
x = 76
Then, plug in 76 as x in the first equation to solve for y:
x + y = 100
76 + y = 100
y = 24
So, 76 balls and 24 bats were purchased.
