Answer:
3
Step-by-step explanation:
Area of ceiling: 6 x 5 = 30 square meters:
Area of 4 walls = 107 - 30 = 77 square meters
2 walls = 6 + 6 = 12 meters long
2 walls = 5 + 5 = 10 meters long
12 + 10 = 22
77 square meters / 22 meters = 3.5 meters
The walls are 3.5 meters high.
Answer:
70 C
Step-by-step explanation:
C = 5/9 * (F-32)
substitute F = 158
C = 5/9 ( 158-32)
Parentheses first
= 5/9 (126)
= 70
Hi!
The answer is one
When you solve this system of equations you get an answer for y and an answer for x.
It looks kinda like this: x=3, y=-4
Thus, your answer is one solution
I hope this helps!

It is necessary to imagine the sum of the areas between each z-score and the average.
Given as the ratio of the area under the normal curve between two z-scores, both above average.
The Z score accurately measures the number of standard deviations above or below the mean of the data points.
The formula for calculating the z-score is
z = (data points – mean) / (standard deviation).
It is also expressed as z = (x-μ) / σ.
- A positive z-score indicates that the data points are above average.
- A negative z-score indicates that the data points are below average.
- A z-score close to 0 means that the data points are close to average.
- The normal curve is symmetric with respect to the mean and needs to be investigated.
Therefore, to find the percentage of the area under the normal curve between two z-scores, both above the mean, you need to look at the sum of the areas between the z-score and the mean.
