Answer:
A.) No
B.) test statistic = - 3.108
Check explanation
Step-by-step explanation:
H0: m = 105 versus H1: m ≠ 105
Sample size, n = 35, since we have a large sample size, greater than 30.
B.)
xbar = 101.9 ; s = 5.9
Test statistic :
T = (xbar - μ) ÷ (s/√n)
T = (101.9 - 105) / (5.9/√35)
T = - 3.1 / 0.9972820
Test statistic = - 3.11
Pvalue from Tstatistic, df = 34
Pvalue = 0.003772( Pvalue calculator)
Pvalue is the probability of obtaining a value more extreme or exactly that of the test statistic.
At α = 0.01
Pvalue < α ; We fail to reject the Null

9514 1404 393
Answer:
[tex]\left[\begin{array}{cc|c}-6&3&-4\\0&-3&11\end{array}\right][/tex]
Step-by-step explanation:
The designated sum can replace either row. Consult your curriculum materials for the intent.
Here, we'll replace row 2 with the sum.
3(2, -2, 5) +(-6, 3, -4) = (3(2)-6, 3(-2)+3, 3(5)-4) = (0, -3, 11)
After the row operation replaces the second row, the augmented matrix is ...
[tex]\left[\begin{array}{cc|c}-6&3&-4\\0&-3&11\end{array}\right][/tex]
Answer:
3(2, -2, 5) +(-6, 3, -4) = (3(2)-6, 3(-2)+3, 3(5)-4) = (0, -3, 11)
After the row operation replaces the second row, the augmented matrix is ...

Hi there!
What we know:
- Sarah has [tex]11 \frac{1}{4}[/tex] pounds of dog food
- Sarah is dividing this into 3 containers
1) Convert [tex]11 \frac{1}{4}[/tex] into an improper fraction
[tex]11 \frac{1}{4}[/tex]
Multiply the whole number by the denominator
11 × 4 = 44
Add 44 to the numerator
44 + 1 = 45
[tex]\frac{45}{4}[/tex]
2) Divide [tex]\frac{45}{4}[/tex] by 3
[tex]\frac{45}{4} / 3[/tex]
Dividing by a number is the same as multiplying its reciprocal
[tex]= \frac{45}{4} *\frac{1}{3}[/tex]
Multiply the numerators and the denominators
[tex]45*1 = 45\\4*3 = 12[/tex]
[tex]= \frac{45}{12}[/tex]
3) Convert [tex]\frac{45}{12}[/tex] into a mixed number fraction
[tex]\frac{45}{12}[/tex] ⇒ [tex]3\frac{3}{4}[/tex]
Therefore, there will be [tex]3\frac{3}{4}[/tex] pounds of food in each container.

Consider the game where two dice, die A and die B, are rolled. We say that die A wins, and write A > B, if the outcome of rolling A is larger than that of rolling B. If both rolls result in the same number it is a tie.
a. find the porbability of a tie
b. find the probabilty that die A wins
Answer:
a) The probability of a tie is the probability of getting the same outcome in both dice.
First, we roll die A and we get a given outcome. (here the probability is 1 because there is no restriction)
Now we need to roll die B and get the same outcome, so here we have only one possible outcome out of 6, then in this case the probability is 1/6
The joint probability (the product of the individual probabilities) is: P = 1*(1/6) = 1/6
b) We want to find the probability that die A wins.
Here we need to analyze each possible outcome for die A.
Let's define:
pₙ = probability of winning given that the outcome is n.
If the outcome is a 1, die A can only lose or tie, then here:
p₁ = 0
If the outcome is a 2, then die A only wins if die B rolls a 1, (1 outcome out of 6)
Then the probability of winning is:
p₂ = 1/6
If the outcome is a 3, then die A wins if die B rolls a 1 or a 2, here we have two possible outcomes out of 6.
p₃ = 2/6
We already can see the pattern, if the outcome is a 4, we get:
p₄ = 3/6
if the outcome is a 5:
p₅ = 4/6
if the outcome is a 6:
p₆ = 5/6
The total probability is the sum of all the joint probabilities:
For each roll in dice A, the probability is 1/6 (the probability of getting a given outcome)
Then the probability that die A wins is:
P = (1/6)*p₁ + (1/6)*p₂ + ... = (1/6)*(p₁ + p₂ + p₃ + p₄ + p₅ + p₆)
P = (1/6)*(0 + 1/6 + 2/6 + 3/6 + 4/6 + 5/6)
P = (1/6)*(15/6) = 0.4167

find the area of each figure. if necessary, leave your answer in simplest form.
Answer:
256 ft^2
Step-by-step explanation:
area of rhombus = half of the product of the diagonals
diagonal 1 = 2 * 12.8 ft = 25.6 ft
diagonal 2 = 2 * 10 ft = 20 ft
area = d1 * d2/2 = 12.8 ft * 20 ft/2 = 256 ft^2
