Answer:
102
Step-by-step explanation:
We have the mean (m) 128.5 and the standard deviation (sd) 8.2, we must calculate the value of z for each one and determine whether or not it is an outlier:
z = (x - m) / sd
In the first case x = 148:
z = (148 - 128.5) /8.2
z = 2.37
In the second case x = 102:
z = (102 - 128.5) /8.2
z = -3.23
In the first case x = 152:
z = (152 - 128.5) /8.2
z = 2.86
The value of this is usually between -3 and 3, therefore when x is 102 it goes outside the range of the value of z, which means that this is the outlier.
Answer:
1587.6 m²
Step-by-step explanation:
where b is the base length and h is the height (b and h on the triangle will always be perpendicular to each other)
Plug in 75.6 m as b and 42 m as h
I hope this helps!
Answer:
y=6x-38
Step-by-step explanation:
That's the answer for C
we know that
1 yard=3 feet
Multiply (89 yards 2 feet) by 14
(89 yards 2 feet)*14=89*14 yards 2*14 feet-------> 1,246 yards 28 feet
convert 28 feet to yards
28 ft=(28/3) yards=9.33 yards
9.33 yards=9 yards+0.33 yards
0.33 yards=1 foot
so
9.33 yards=9 yards+1 foot
substitute
1,246 yards 28 feet=1,246 yards +9 yards+1 foot----->1,255 yards + 1 foot
therefore
<u>the answer is the option</u>
C. 1,255 yards 1 foot
