Answer:
2 gallons
Step-by-step explanation:
You have to find the pattern of adding and draining water for 15 days. To get there you need to subtract 2 and add 1 but keep the negative/positives the same i.e. (this is for the 10ths of gallons)
13-2=11
11+1=10
keeping the pattern for 15 days:
+13, 11,+12,-10,+11,-9,+10,-8,+9,-7,+8,-6,+7,-5,+6 = 20 (10ths of gallons)
20/10 = 2

A square has a perimeter of 51.6 inches. What is the length of each side?
13 inches
129 inches
12.9 inches
1.29 inches
Answer:
12.9
Step-by-step explanation:
A square has even lengths on each side. Since there is 4 sides on a square. We divide perimeter by 4.
51.6/4 = 12.9 inches
The length of each side of the square is 12.9 inches if perimeter of square is 51.6 inches.
What is Quadrilateral?A quadrilateral is defined as a two-dimensional shape with four sides, four vertices, and four angles.
The perimeter of a square is the sum of the lengths of all its sides.
Let a be the length of each side of the square, then the perimeter P is given by:
P = 4a
We are given that the perimeter is 51.6 inches, so we can set up the equation:
51.6 = 4a
Solving for a, we divide both sides by 4:
a = 51.6/4
a = 12.9
Therefore, the length of each side of the square is 12.9 inches if perimeter of square is 51.6 inches.

What is x?
Answer:
-8
Step-by-step explanation:
-4 both sides & 16-4 is 12.. -3/2x equals 12 so to solve for x, you would multiply 2 by both sides. You end w -3x equals 24. You then divide -3 both sides and 24/-3 is -8... hopee that helps? :)

A.
18.058
B.
34.060
C.
35.13
D.
43.05
E.
54.06
Answer:
The answer would be C Hope this helps :)
Step-by-step explanation:
Answer:
C, D, E
Step-by-step explanation:
A. and B. are both less than or equal to 34.06. The others are greater than 34.06
can be tested by subtracting 34.06 by the other numbers and with a negative result, it is greater than 34.06. for example 34.06 - E. (54.06) = -20
so E(54.06) is greater than 34.06. If you couldn't already tell.
B is incorrect because it is equal to 34.06. A also is incorrect. This is because it is less than 34.06. 34.06 - A.(18.058) = 16.002. The result of a positive number means it is less than the number on the right of the inequality sign.

Please fast ! What mathematical term do we use for the first part of proof ?
Answer:
A mathematical proof is an inferential argument for a mathematical statement, showing that the stated assumptions logically guarantee the conclusion.The argument may use other previously established statements, such as theorems; but every proof can, in principle, be constructed using only certain basic or original assumptions known as axioms, along with the accepted rules of inference.

A study was designed to compare the attitudes of two groups of nursing students towards computers. Group 1 had previously taken a statistical methods course that involved significant computer interaction. Group 2 had taken a statistic methods course that did not use computers. The students' attitudes were measured by administering the Computer Anxiety Rating Scale (CARS). A random sample of 12 nursing students from Group 1 resulted in a mean score of 59.7 with a standard deviation of 2.8. A random sample of 15 nursing students from Group 2 resulted in a mean score of 64.7 with a standard deviation of 8.3. Can you conclude that the mean score for Group 1 is significantly lower than the mean score for Group 2? Let µ1 represent the mean score for Group 1 and µ2 represent the mean score for Group 2. Use a significance level of α = 0.1 for the test. Assume that the population variances are equal and that the two populations are normally distributed.Step 1: State the null and alternative hypotheses for the test.Step 2: Compute the value of the t test statistic. Round your answer to three decimal placesStep 3: Determine the decision rule for rejecting the null hypothesis H0. Round your answer to three decimal places. Reject or fail to reject your hypothesis?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Group 1:
μ1 = 59.7
s1 = 2.8
n1 = sample size = 12
Group 2:
μ2 = 64.7
s2 = 8.3
n2 = sample size = 15
α = 0.1
Assume normal distribution and equ sample variance
A.)
Null and alternative hypothesis
Null : μ1 = μ2
Alternative : μ1 < μ2
B.)
USing the t test
Test statistic :
t = (m1 - m2) / S(√1/n1 + 1/n2)
S = √(((n1 - 1)s²1 + (n2 - 1)s²2) / (n1 + n2 - 2))
S = √(((12 - 1)2.8^2 + (15 - 1)8.3^2) / (12 + 15 - 2))
S = 6.4829005
t = (59.7 - 64.7) / 6.4829005(√1/12 + 1/15)
t = - 5 / 2.5108165
tstat = −1.991384
Decision rule :
If tstat < - tα, (n1+n2-2) ; reject the Null
tstat < t0.1,25
From t table :
-t0.1, 25 = - 1.3163
tstat = - 1.9913
-1.9913 < - 1.3163 ; Hence reject the Null

ALMN and A NOP similar right triangles. The coordinates of all the vertices are integers.
A. The relationship between the slope of LN and the O slope of NP cannot be determined, because the triangles are congruent.
B.The slope of LN is greater than the slope of NP This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for LN than for NP.
C.The slope of LN is less than the slope of NP This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is less for LN than for NP
D. the slope of LN is equal to the slope of NP. this this because ratio of the change in x values of the endpoints is the same for LN as for NP
Answer:
D . the slope of LN is equal to the slope of NP. this this because ratio of the change in x values of the endpoints is the same for LN as for NP
Step-by-step explanation:
LMN and A NOP similar right triangles. The coordinates of all the vertices are integers.
Since the triangles are similar, we can the ratio of the sides are equal
OP NM
----- = -----
NO LM
OP/ NO is the slope of LN and
NM/ LM is the slope of NP
They are equal so the slopes are the same

At the start of a soccer game, the referee flips a coin to determine which team gets the ball first. The referee making
the calls for your upcoming game has seen the last 5 coin flips come up tails. The team captain plans to call heads
during the coin flip because he says it is long overdue.
Is your friend's reasoning correct?
O Yes, the coin flip is more likely to come up heads in order for the probability of heads to get back to 0.5.
No, it is highly unlikely to get 5 tails in a row by chance alone, so the friend should continue to go with tails. This
referee must be using an unfair coin.
O No, the probability of getting heads or tails is 0.5, regardless of the outcomes of the previous flips.
Yes, after so many tails in a row, the coin is due to show heads.
Answer: The answer is C on Edge 2020
Step-by-step explanation:
Answer:
(C) No, the probability of getting heads or tails is 0.5, regardless of the outcomes of the previous flips.
