Goodmorning I need help with this question. And may you explain to me how to get this right step by step. Thank you.
Answer:
I think it's "C"
Step-by-step explanation:
Because a function is the independent variable to the dependent variable... Since, the cost relies on the weight, the cost is dependent. While, the weight is independent. I don't know if I'm right, I kinda suck at math

The Place valueof Thedigit 5 in 26,59,360 in Ten Thousand
Answer: True.
Step-by-step explanation:
Here we have the number:
26,59,360
To find the place value of the 5, we first need to count the number of decimals at the right of the 5 (until we reach the decimal point)
For this case, at the left of the 5 we have 4 decimals (9, 3, 6 and 0)
Then the place value of the 5 in that number will be 10^4
this is equal to:
10^4 = (10)*(10)*(10)*(10) = 10,000
This means that the place value of the 5 is then thousand.
Then the statement is true.

Joe-Bob wants to buy a car and will need to take out a loan in order to make the purchase. His current monthly income is $3,500 per month. His mortgage payment is $900 per month, and his student loan payment is $350 per month.
Note: You do not need to take taxes into consideration for this journal.
According to the affordability formulas given, can he afford to take out another loan?
When should he follow the affordability formulas? In what cases should he not?
How could taking out the car loan impact his other priorities?
Determine if each sequence is arithmetic, geometric, or neither.
4, 8, 16, 32, 64, . . .
-8, -4, 0, 4, 8, . . .
2, 3, 5, 8, 13, . . .
9514 1404 393
Answer:
geometricarithmeticneither (Fibonacci sequence)Step-by-step explanation:
If ratios are the same, it is geometric:
8/4 = 16/8 = ... = 2
If differences are the same, it is arithmetic:
-4-(-8) = 0 -(-4) = ... = 4
If neither is the case, it is neither:
3-2 ≠ 5 -3
3/2 ≠ 5/3
In this last sequence we see that differences equal the previous term. This is characteristic of the Fibonacci sequence, which sees wide use in Nature, and has a relationship to the Golden Ratio. (The ratios of successive terms approach the golden ratio (1+√5)/2 ≈ 1.618.)

Find the Area of the figure below, composed of a parallelogram and one semicircle. Rounded to the nearest tenths place
Please see the picture
Test
I only have 10 minutes left
Answer:
Area of the figure= area of the rectangle+ area of the semicircle
=(15×14)+(1/2)π(7)²=210+77=287 square unit
287 square unit is the right answer.
Remember:--- area of the rectangle
=(length×breadth)
and area of the semicircle=π(radius)²/2
The competitive advantage of small American factories such as Tolerance Contract Manufacturing lies in their ability to produce parts with highly narrow requirements, or tolerances, that are typical in the aerospace industry. Consider a product with specifications that cal for a maximum variance in the lengths of the parts of 0.0008. Suppose the sample variance for 30 parts turns out to be
s2 = 0.0009.
Use
α = 0.05
to test whether the population variance specification is being violated.
State the null and alternative hypotheses.
H0: σ2 ≤ 0.000
Ha: σ2 > 0.0008
H0: σ2 = 0.0008
Ha: σ2 ≠ 0.0008
H0: σ2 ≥ 0.0008
Ha: σ2 < 0.0008
H0: σ2 > 0.0008
Ha: σ2 ≤ 0.0008
H0: σ2 < 0.0008
Ha: σ2 ≥ 0.0008
Find the value of the test statistic.
Find the p-value. (Round your answer to four decimal places.)
p-value =
State your conclusion.
A. Reject H0. The sample does support the conclusion that the population variance specification is being violated.
B. Reject H0. The sample does not support the conclusion that the population variance specification is being violated.
C. Do not reject H0. The sample does support the conclusion that the population variance specification is being violated.
D. Do not reject H0. The sample does not support the conclusion that the population variance specification is being violated.
Answer:
1. H0: σ2 ≤ 0.0008
Ha: σ2 > 0.0008
2. test statistic = 32.625
3. p value = 0.2931
4. D
Step-by-step explanation:
s² = 0.0009
alpha = 0.05
σ² = 0.0008 this is the value that we would be testing
1. hypothesis:
H0: σ2 ≤ 0.0008
Ha: σ2 > 0.0008
2. test statistic:
X² = (n-1/σ²)s²
= ((30-1)/0.0008)0.0009
= 32.625
3. p-value:
P(X² > 32.63) = 0.2931
4. conclusion:
the p-value at 0.2931 is greater than alpha at 0.005, (0.2931>0.05). So the correct option is D. we do not reject H0. the sample does not support conclusion that the population variance specification is being violated.

at the produce store Wendy sees that grapes cost 13.50 for 3 pounds what is the unit rate
Answer:
Step-by-step explanation:
when you are asked for a unit rate it is always something like this
$5 /pound or 2.2 pounds/ kg
We set up the equation like this:
$13.50/3 pounds
So, for this we need to get 3 pounds down to 1 pound. Also, to make the eqaution balance we need to divide $13,50 by 3 too!
So, the unit rate is $4.5/pound or $4.5 per pound.

a. four of a kind?
b. Two different pairs
c. a pair of jacks and a pair of 8's
d. a pari of jacks or a pair of 8's but not both
Answer:
Probability of Four of a Kind
The probability of being dealt four of a kind is 0.0002400960384. On average, four of a kind is dealt one time in every 4,165 deals.
Probability of Two Pair
On average, players get two pair about one time in every 21 deals.
Step-by-step explanation:
Probability of Four of a Kind
Let's execute the analytical plan described above to find the probability of four of a kind.
First, we count the number of five-card hands that can be dealt from a standard deck of 52 cards. This is a combination problem. The number of combinations is n! / r!(n - r)!. We have 52 cards in the deck so n = 52. And we want to arrange them in unordered groups of 5, so r = 5. Thus, the number of combinations is:
52C5 = 52! / 5!(52 - 5)! = 52! / 5!47! = 2,598,960
Hence, there are 2,598,960 distinct poker hands.
We count the number of ways that five cards can be dealt to produce four of a kind. It requires three independent choices to produce four of a kind:
Choose the rank of the card that appears four times in the hand. A playing card can have a rank of 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king, or ace. For four of a kind, we choose 1 rank from a set of 13 ranks. The number of ways to do this is 13C1.
Choose one rank for the fifth card. There are 12 remaining ranks, from which we choose one. The number of ways to do this is 12C1.
Choose a suit for the fifth card. There are four suits, from which we choose one. The number of ways to do this is 4C1.
The number of ways to produce four of a kind (Num4) is equal to the product of the number of ways to make each independent choice. Therefore,
Num4 = 13C1 * 12C1 * 4C1 = 13 * 12 * 4 = 624
Conclusion: There are 624 different ways to deal a poker hand that can be classified as four of a kind.
Finally, we compute the probability. There are 2,598,960 unique poker hands. Of those, 624 are four of a kind. Therefore, the probability of being dealt four of a kind (P4) is:
P4 = 624 / 2,598,960 = 0.0002400960384
The probability of being dealt four of a kind is 0.0002400960384. On average, four of a kind is dealt one time in every 4,165 deals.
Probability of Two Pair
To find the probability for two pair, we execute the same analytical plan that we've used to compute the other probabilities.
There are 2,598,960 distinct poker hands.
Next, count the number of ways that five cards can be dealt to produce two pair. It requires five independent choices to produce two pair:
Choose the rank for cards of matching rank. A playing card can have a rank of 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king, or ace. For two pair, we choose 2 ranks from a set of 13 ranks. The number of ways to do this is 13C2.
Choose the rank of the remaining non-matching card. There are 11 remaining ranks, from which we choose one. The number of ways to do this is 11C1.
Choose suits for the first two-card combination. There are four suits, from which we choose two. The number of ways to do this is 4C2.
Choose suits for the second two-card combination. There are four suits, from which we choose two. The number of ways to do this is 4C2.
Choose a suit for the non-matching card. There are four suits, from which we choose one. The number of ways to do this is 4C1.
The number of ways to produce two pair (Numtp) is equal to the product of the number of ways to make each independent choice. Therefore,
Numtp = 13C2 * 11C1 * 4C2 * 4C2 * 4C1
Numtp = 78 * 11 * 6 * 6 * 4 = 123,552
Finally, compute the probability. There are 2,598,960 unique poker hands. Of those, 123,552 are two pair. Therefore, the probability of being dealt two pair (Ptp) is:
Ptp = 123,552 / 2,598,960 = 0.04753901561
On average, players get two pair about one time in every 21 deals.
