Answer:
1
Step-by-step explanation:
The absolute value of -3 is 3, so 4-3=1
Answer:
see explanation
Step-by-step explanation:
The perimeter of a rectangle = 2l + 2w ( l is length and w is width )
given w = 63, then
2l + (2 × 63) = 324
2l + 126 = 324 ( subtract 126 from both sides )
2l = 198 ( divide both sides by 2 )
l = 99 m ← length of garden
-----------------------------------------------------------------
The area of a rectangle = lw ( l is length and w is width )
given l = 94, then
94w = 5828 ( divide both sides by 94 )
w = 62 cm ← width of window
Answer:
A. -1.6; not significant
Step-by-step explanation:
The z-score of a data set that is normally distributed with a mean of 
and a standard deviation of 
, is given by:
.
From the question, the test score is: 
, the mean is 
, and the standard deviation is 
.
We just have to plug these values into the above formula to obtain:
.
This simplifies to: 
.
.
We can see that the z-score falls within two standard deviations of the mean.
Since 
the value is not significant.
The correct answer is A. -1.6; not significant
the square root between 4 and 5 is \sqrt{24}.
