Answer:
x= 13
both angles are equal to 106
Step-by-step explanation:
8x + 2= 14x - 76
-8x +76 - 8x +76
78 = 6x
78/6 = 13
8 (13) + 2 = 104 + 2 = 106
14(13) - 76 = 182 - 76 = 106
Answer: Option (c) is correct.
68% of the data points lie between 10 and 18.
Step-by-step explanation: Given : a normal distribution with a standard deviation of 4 and a mean of 14
We have to choose the sentence that correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14.
Since, given 68% data.
We know mean of data lies in middle.
And standard deviation is distribute equally about the mean that is 50% of values less than the mean and 50% greater than the mean.
So, 68% of data lies
mean - standard deviation = 14 - 4 = 10
mean + standard deviation = 14 + 4 = 18
So, 68% of the data points lie between 10 and 18.
Answer:
81x^4+216x^3+216x^2+96x+16
Step-by-step explanation:
Answer:
To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.
m= 2.5x is the equation you want to use, hope this helped! <3
