Answer:
y = 2
Step-by-step explanation:
use slope formula:
(4 - y) / (3 - 10) = -2/7
4-y / -7 = -2 /7
cross-multiply:
7(4 - y) = (-7)(-2)
28 - 7y = 14
-7y = -14
y = 2
Answer:x=-2.30
Step-by-step explanation:
6.95x+16.2-2.36x=3.2x+13
6.95x-2.36x+16.2=3.2x+13
4.59x+16.2=3.2x+13
4.59x-3.2x+16.2=13
1.39x+16.2=13
1.39x+16.2-16.2=13-16.2
1.39x=-3.2
1.39x÷1.39=-3.2÷1.39
X=-2.30
Answer:
$52,936
Step-by-step explanation:
1400(.14)(4) + 4(6)(9.75) = 784 + 234 = $1018/week
52(1018) = $52,936
Answer: 40.13% of the soda bottles will have a volume less than 32 oz.
First, we need to find the z-score. That is the number of standard deviations below the mean.
(32 - 32.3) / 1.2 = -0.25
A bottle of 32 oz is -0.25 standard deviations below the mean. Use a standard normal distribution probability table and you will find the 40.13% of the scores are below a z-score of -0.25.
