Using the Pythagorean theorem:
15^2 = 12^2 + X^2
225 = 144 + x^2
X^2 = 225 - 144
x^2 = 81
x = √81
x = 9
The distance is 9 feet.
The answer is A.
Answer:
There is no difference as per statistical evidence.
Step-by-step explanation:
We calculate t statistic from the formula
t =difference in means/Std error of difference
Here n1 = n2
t = (x bar - y bar)/sq rt of s1^2+s2^2
Let treatment I =X = 34 41 38 29
Treatment II Y = 39 48 35 36
X Y
Mean 35.50 39.50
Variance 81.00 105.00
H0: x bar = y bar
Ha: x bar not equal to y bar
(Two tailed test at 0.05 significant level)
N1 = 4 and N2 = 4
df=N1+N2-2 = 6
s1^2 = 81/3 =27 and s2^2 = 105/3 = 35
Std error for difference =
t = -1.02
p =0.348834
p>0.05
Since p value >alpha we accept null hypothesis.
Hence there is statistical evidence to show that there is no difference in the mean level of scores.
Answer:
they sold 14 pizzas all day.
Step-by-step explanation:
4 x 2 = 8
0.5 means half of what they sold in the afternoon
4 ÷ 2 = 2
now add them both together to get the number of pizzas they sold at night.
8 + 2 = 10
now add the afternoon and night together
10 + 4 = 14
answer: 14 pizzas

Answer:
the limit does not exist
Step-by-step explanation:
As x approaches π/2 from below, tan(x) approaches +∞. A x approaches π/2 from above, tan(x) approaches -∞. These two limits are not the same, so the limit is said not to exist.
___
For a limit to exist, it must be the same regardless of the direction of approach.
