Xy = -112
x + y = -54
x + y = -54
2 + y = -54
- 2 - 2
y = -56
(x, y) = (2, -56)
or
x + y = -54
-56 + y = -54
+ 56 + 56
y = 2
(x, y) = (-56, 2)
The two numbers that multiply to -12 and add up to -54 are -56 and 2.
Answer:42.6
Step-by-step explanation:
14.20 x3=42.6
25x^2-49 = 0
+49. +49
////. 49
25x^2=49
that's the best I got, sorry I tried
hope it helps
Using the normal distribution, considering it's symmetry, it is found that the value of C is of 2.19.
<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.
The standard normal distribution has mean and standard deviation given, respectively, by:
.
Hence, considering the symmetry of the normal distribution, the value of c is <u>Z with a p-value of (1 + 0.9715)/2 = 0.98575</u>, hence c = Z = 2.19.
