28% + 34% + 18%+17% = 97%
100% - 97% = 3%
$3800 * 0.03 = $114 ( for one month )
For the entire year: $114 * 12 = $1,368
Answer:
They plan to spend $1,368 on team sponsorship for the entire year.
Picture with the red boxes inside the ANSWER is the first choice
4n+4
4(1)+4= 8 white boxes in figure 1
4(2)+4= 12 white boxes in figure 2
4(3)+4= 16 white boxes in figure 3
4(4)+4=20 white boxes in figure 4
Answer:
1.
The null hypothesis
H0: Ud=0
The alternate hypothesis
H1:Ud≠0
2. Test statistic = -3.04
3. P value = 0.039
4. Reject h0
Step-by-step explanation:
X = right arm
Y = left arm
d = difference between both arms
X. Y. d(x-y). d²
145. 173. -28. 784
142. 163. -21. 441
116. 182. -66. 4356
133. 148. -15. 225
134. 149. -15. 225
Total
d = -145
d² = 6031
We have sample space n = 5
d' = -145/5
= -29
Sd = √1/n-1(Σd²-(Σd)²/n
Sd = √1/4(6031-(-145)²/5
= √1/4(6931-4205)
= √456.5
= 21.366
To get t
=d'/(sd/√n)
= -29/(21.366/√5)
= -3.035
In summary
This is a two tailed test
1.
The null hypothesis
H0: Ud=0
The alternate hypothesis
H1:Ud≠0
2. Test statistic = -3.04
3. P value = 0.039
4. We have pvalue to be 0.039 which is less than the level of significance 0.05
0.039<0.05, so we take decision to reject h0 which is the null hypothesis
We have enough evidence to support claim that there is a measurement difference between left and right arms
Very easy!
6 people= 12 servings so 1 person= 2 servings
We have 112 people so we need 112 x 2= 224 servings
So she will make 224 servings with an 8 servings pan, 224/8= 28 pans.
The minimum number of pans she need in order to serve 112 people is 28 pans!
Answer:
Step-by-step explanation:
1) Factor using polynomial division.
2) Rewrite in the form , where a = x and b = 5.
3) Use Square of Sum: .
