3x + 15 because u add all the x and then all real numbers
XY smaller than XZ smaller than YZ
The greatest side is opposite to the greatest angle, and the smallest side is opposite to the smallest angle
Answer:
3) 36
2) 55
Step-by-step explanation:
We have to place the numbers in order from least to greatest.
3) 23, 26, 26, 32, 32, 36, 50, 52, 52, 52, 59,
4) 40, 42, 49, 54, 62, 67, 67, 70, 95
The more is the the difference between the lowest and highest values.
95-40=55
Using the normal distribution, it is found that 25.14% of the batteries will last more than 420 hours.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
In this problem, we have that the mean and the standard deviation are given, respectively, by:
.
The proportion of the batteries will last more than 420 hours is <u>one subtracted by the p-value of Z when X = 420</u>, hence:
Z = 0.67
Z = 0.67 has a p-value of 0.7486.
1 - 0.7486 = 0.2514.
0.2514 = 25.14% of the batteries will last more than 420 hours.

Answer:
x=-10, y=-20
Step-by-step explanation:
Since both 2x and 3x+10 equals y, they equal each other.
2x = 3x + 10
x = -10
Substitute -10 for x
2(-10) = y
y=-20
