Answer:
Option 3 and 4.
Step-by-step explanation:
The z score shows by how many standard deviations the raw score is above or below the mean. The z score is given by:
Given that mean (μ) = 82, standard deviation (σ) = 5
1) For x = 74:
Option 1 is incorrect
2) For x < 87
From the normal distribution table, P(x < 87) = P(z < 1) = 0.8413 = 84.13%
Option 2 is incorrect
3) For x = 95:
Option 3 is correct
4) For x < 77
From the normal distribution table, P(x < 77) = P(z < -1) = 0.16 = 16%
Option 4 is correct
5) For x > 92
From the normal distribution table, P(x > 92) = P(z > 2) = 1 - P(z < -2) = 1 - 0.9772 = 0.0228 = 2.28%
Option 5 is incorrect
6x=4.50
x = price per container
x=4.50 / 6
x= .75 per container
.75 * 8containeers = $6
Answer:
Car 1 - 25
Car 2 - 30
Step-by-step explanation:
Assuming we use car 2 as much as possible than car 2 consumed 30 gallons while car 1 consumed 25
(35x30)+(15x25)=1425
30+25=55
Sorry if this is wrong. I tried my best, if it is wrong than tell me so I will know and can try to improve.
Answer: slope = 85
y-intercept = -14/5
Step-by-step explanation:
i took the test on k12 trust me this was the answer
-3pa - 9b - 18pc
For starters, you know that you can't take away any of the letters from the equation because none of the three have the exact same letter; however, they all have something they can be divided by and that is -3.
It would be -3 instead of just 3 because the equation itself starts with a negative. (you could probably do it anyways with just 3, but you'd end up taking out a negative one, anyways, so what's the point?)
Now, you would have: -3 ( pa + 3b + 6pc )
That is truly all you can take out. So, that would end up being your answer since all you can really do is simplify.
