Answer:
70,176
Step-by-step explanation:
Given that
482 - 412 + 286 - 12 × 204
We need to solve the above equation
= 482 - 412 + 286 - 12 × 204
= 70 + 286 - 12 × 204
= 356 - 12 × 204
= 344 × 204
= 70,176
Hence, the answer to the given equation is 70,176

Answer:
41101.750 to 43898.250
Step-by-step explanation:
Using this formula X ± Z (s/√n)
Where
X = 42500 --------------------------Mean
S = 6800----------------------------- Standard Deviation
n = 64 ----------------------------------Number of observation
Z = 1.645 ------------------------------The chosen Z-value from the confidence table below
Confidence Interval Z
80%. 1.282
85% 1.440
90%. 1.645
95%. 1.960
99%. 2.576
99.5%. 2.807
99.9%. 3.291
Substituting these values in the formula
Confidence Interval (CI) = 42500 ± 1.645(6800/√64)
CI = 42500 ± 1.645(6800/8)
CI = 42500 ± 1.645(850)
CI = 42500 ± 1398.25
CI = 42500+1398.25 ~. 42500-1398.25
CI = 43898.25 ~ 41101.75
In other words the confidence interval is from 41101.750 to 43898.250
To find a 90% confidence interval for the mean starting salary, use the formula CI = sample mean ± (Z * sample standard deviation / √n).
To find a 90% confidence interval for the mean starting salary, we will use the formula:
CI = sample mean ± (Z * sample standard deviation / √n)
Given that the sample mean is $42,500, the sample standard deviation is $6,800, and the number of college graduates is 64, we can substitute these values into the formula to calculate the confidence interval. The lower-bound is $41,101.87 and the upper-bound is $43,898.13.

Answer:
Step-by-step explanation:
We have been given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -1.5.
To find Sally's temperature we will use z-score formula.
, where = Mean, = Standard deviation.
Let us substitute our given values in z-score formula.
Multiply 0.62 to both sides of equation.
Add 98.20 to both sides of equation.
Therefore, Sally's temperature will be 97.27 degrees Fahrenheit.
Explain your reasoning.
Answer:
No! Both are wrong!
Step-by-stepExplanation:
the value of absolute function, (|.|) is always positive
that means -6x always has to be positive
and for -6x to be positive x has to be negative
(since, two negatives make a positive)
therefore, the value of x to the equation will be a negative value and not a positive one.
Ana thinks both positive and negative values of x will be the solution, whereas Ling thinks negative value of x can't be a solution. So, they're both wrong.
ONLYnegativevalue of x will be the solution.
