What is the sum of 1 and opposite of 12

likoan [24]

The opposite of 12 is -12 . To add negative numbers to positive numbers count backwards, as if you were subtracting. We have the problem: 1+ (-12). This can be read as “one plus negative twelve.” This can also be read as 12-1 which is 11 so the answer is 11.

Please help ill give brainliest

Answer:

y = 7/8x + 1

Step-by-step explanation:

According to y = mx + b, whereas b is the y-intercept

so if b is positive, b has to be larger than 0

You recently took a statistics exam in a large class. The instructor tells the class that the scores were Normally distributed,

Lunna [17]

Answer:

b. the area to the right of 2

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X, which is also the area to the left of Z. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X, which is the area to the right of Z.

In this problem:

$X = 96, \mu = 72, \sigma = 12$
