First, plug in 5 for x:
| -5 * 5 + 12 | = |-25 + 12| = |-13|
Those two lines are absolute value, which measures the distance from the number to 0 on a number line. This distance is always positive.
The distance from -13 to 0 on a number line is 13. The answer is 13.
Answer:
Step-by-step explanation:
Given that:
Population Mean = 7.1
sample size = 24
Sample mean = 7.3
Standard deviation = 1.0
Level of significance = 0.025
The null hypothesis:
The alternative hypothesis:
This test is right-tailed.
Rejection region: at ∝ = 0.025 and df of 23, the critical value of the right-tailed test 
The test statistics can be computed as:
t = 0.980
Decision rule:
Since the calculated value of t is lesser than, i.e t = 0.980 < , then we do not reject the null hypothesis.
Conclusion:
We conclude that there is insufficient evidence to claim that the population mean is greater than 7.1 at 0.025 level of significance.
You can write 1/4 as a decimal, equivalent fraction, and a percent.
To change 1/4 into a decimal, divide the numerator by the denominator. You will get 0.25. To make 1/4 into a percent, multiply the decimal by 100 or just move the decimal two places to the right. The percent is 25%. To make 1/4 into another equivalent fraction, multiply the numerator and denominator by the same number. For example, you can multiply the numerator by 2 and the denominator by 2. So, another equivalent fraction for 1/4 is 2/8.
Hope it helps :)
Answer: =5x−10
Step-by-step explanation: hope this help
Let's simplify step-by-step.
3(3x−4)−2(2x−1)
Distribute:
=(3)(3x)+(3)(−4)+(−2)(2x)+(−2)(−1)
=9x+−12+−4x+2
Combine Like Terms:
=9x+−12+−4x+2
=(9x+−4x)+(−12+2)
Answer: =5x+−10
