23 inches
x = mindy's height
2x - 20 = 66
-20 -20
2x = 46
/2 /2
x = 23
168 is the area, because if you want to find the area of something, you could multiply the numbers, to find the area.
Hope this helps :)
Answer:
a = -4.3
Step-by-step explanation:
a+(−1.2)=−5.5
a - 1.2 = - 5.5
a = - 5.5 + 1.2
a = - 4.3
Answer:
Calculating (5 x 2) violates the order of operations
Step-by-step explanation:
According to the order of operations, multiplies all have equal priority. Therefore, they must be evaluated left to right, not right to left. Evaluating (5 x 2) first is incorrect, and instead (9 x 5) should be calculated first.
Answer: it is a right tailed probability
Step-by-step explanation:
Population proportion = 26.9/100 = 0.269
We are dealing with the fact that the probability that the mean bond percent for the sample will be at least 28. This means that the sample proportion is 0.28 or above. This means that it is greater than the population proportion of 0.269
The hypothesis would be
For null hypothesis
p = 0.269
For alternative hypothesis,
p > 0.269
The inequality sign means that it is right tailed.
