Answer:
4 and -4
Step-by-step explanation:
absolute value is always going to be positive and the overall value will only change if it is negative. so the "|4|" (absolute value of 4) is the same as "|-4|" (absolute value of negative 4)
Answer: none
1) combine like terms: 4x + 8 = 4x - 13
2) Add 13 to both sides (addition property of equality)
3) Subtract 4x from both sides (subtraction property of equality)
4) 21 does not equal 0
Answer:
Find the highest (8.9°C) temperature and subtract it by the lowest (-13.4°C)
8.9°C - (-13.4°C) = 22.3
The difference in temperature on the coldest and warmest day is 22.3°C
Answer:
D. With a p-value of 0.305, we do not have statistically significant evidence that the population mean distance traveled to class is different for men and women.
Step-by-step explanation:
What we are testing?
If the distance students travel to get from class is statistically different for men and women.
How we take the decision?
The significance level is the standard of 0.05.
If the p-value is greater than 0.05, there is no evidence that the distances are statistically different for the population.
If the p-value is less than 0.05, there is evidence that the distances are statistically different different for the population..
In this question:
p-value: 0.305 > 0.05, so there is no statistically significant evidence that the means are difference, and the correct answer is given by option d.
Answer:
1: 45
2: 32
3: 35
4: 32
Step-by-step explanation:
when finding the area of a trapezium you can also just split the rectangle and triangle to have 2 different areas then combine to have the same area. but also this would be more difficult if you needed to separate the trapezium into more than 3 shapes.
so if there is like a trapezoid that you split and there is a rectangle and 2 triangles it is harder than doing the formula.
so use the formula sometimes too if it is easier.
