In a large high school, 18% of sophomores and 67% of seniors have part-time jobs. Suppose random samples of 32 sophomores and 31 seniors from this high school are asked if they have a part-time job. Let p hat Subscript under and p hat Subscript upper be the sample proportions of sophomores and seniors, respectively, who have part-time jobs. Which of the following is the correct shape and justification of the sampling distribution of P hat Subscript under Baseline minus p hat Subscript upper ? bimodal because one population proportion is centered at 0.18, while the other is centered at 0.67 approximately Normal because the expected numbers of successes and failures for each sample are all at least 10 not approximately Normal because the expected numbers of successes and failures for each sample are all at least 10 not approximately Normal because the expected numbers of successes and failures for the sophomores group are not both at least 10
Using the Central Limit Theorem, it is found that the correct statement is given by:
bimodal because one population proportion is centered at 0.18, while the other is centered at 0.67.
What does the Central Limit Theorem state?It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex]
In this problem, for sophomores, we have that:
np = 32 x 0.18 = 5.76 < 10.
Hence the distribution cannot be normal, which means that the correct statement is:
bimodal because one population proportion is centered at 0.18, while the other is centered at 0.67.

Consider the sequence of steps to solve the equation: 3(x - 4) + 5x = 9x - 36
Given = 3(x - 4) + 5x = 9x - 36
Step 1 = 3x - 12 + 5x = 9x - 36
Step 2 = 3x + 5x - 12 = 9x - 36
Step 3 =› 8x - 12 = 9x - 36

Ten blackberry plants start growing in my yard. Absent constraint, blackberries will spread by 200% a month. My yard can only sustain about 50 plants. Using the logistic growth model, a. Write a recursive formula for the number of blackberry plants in my yard b. Calculate the number of plants after 1, 2, and 3 months
The recursive formula for the number of blackberry plants in my yard is Tn = 3Tn-1 where To = 10
The recursive functionThe given parameters are:
Initial = 10Maximum = 50Growth rate = 200%The number of plants in month n is calculated using:
Tn = Tn-1 * (1 + 200%)
This gives
Tn = 3Tn-1
Hence, the recursive formula for the number of blackberry plants in my yard is Tn = 3Tn-1 where To = 10
The number of plants after 1, 2, and 3 monthsThis means that n = 1, 2, 3
When n = 1, we have:
T1 = 3To = 3 * 10 = 30
When n = 2, we have:
T2 = 3T1 = 3 * 30 = 90
90 is greater than the maximum number of plant the backyard can contain
Hence, the number of plants after 1 month is 30 and the plants in the backyard would exceed 50 plants before the end of the 2 months

(50 POINTS! PLEASE HELP!) Alang has a bag that contains pineapple chews, strawberry chews, and lime chews.
He performs an experiment. Alang randomly removes a chew from the bag, records
the result, and returns the chew to the bag. Alang performs the experiment 26 times.
The results are shown below:
A pineapple chew was selected 20 times.
A strawberry chew was selected 4 times.
A lime chew was selected 2 times.
Based on these results, express the probability that the next chew Alang removes
from the bag will be lime chew as a fraction in simplest form.
Answer:
1/13
Step-by-step explanation:
Probability (lime chew) :
No. of times lime chew was selected / Number of times experiment was conducted2/261/13The probability that the next chew Alang removes from the bag will be lime chew is 1/13.
What is probability?The likelihood or chance of an event occurring is quantified by probability. It is represented by a number between 0 and 1, with 0 denoting an impossibility and 1 denoting a certainty.
For instance, there is only one outcome (rolling a "6") that result in the desired event, hence the chance of rolling a "6" on a fair six-sided die is 1/6. (rolling a "6"). , there is a 1/6 chance of rolling any other number.
By dividing the number of times a lime chew was chosen by the total number of trials, the likelihood of choosing a lime chew could be computed (26).
The likelihood of choosing a lime chew is; 2/26, which reduces to 1/13 in basic form.
Therefore, 1/13 is the probability.

f - green (A)
f' - red (B)
f'' - blue (C)
The graph of f attains local extrema at the same points that f' = 0. There's evidence of this at x = 0 and between x = 3 and x = 3.5. (At both points, curve A attains a maximum, while curve B crosses the x-axis.)
Similarly, the graph of f' attains local extrema at the same points that f'' = 0. This is seen between x = 1.5 and x = 2. (B has a max, C crosses axis)
Also, the graph of A is continuous at x = 1.5 but exhibits a sharp turn, so at this point f is not differentiable and the graph of f' (and subsequently f'') is not continuous.

The second angle of a triangle is 4 less than the first angle. The third angle is two times the first. Find the three angles.
The measure of the three angles are 46, 42 and 92 degrees respectively
Sum of angles in a triangleA triangle is a shape that has 3sides and angles
Let the measure of the angles be x, y and z
If the second angle of a triangle is 4 less than the first angle, then;
y = x - 4
If the third angle is two times the first, then z = 2x
Since the sum of interior angle is 180 degrees, hence;
x + y + z = 180
x +x - 4 + 2x = 180
4x = 184
x = 46
Second angle = x - 4
Second angle = 42 degrees
Third angle = 2(46) = 92 degrees

What is the distance between parallel lines y=x+3 and y=x+1, rounded to the nearest hundredth?
Answer:
The distance is 1.41 to nearest hundredth.
Step-by-step explanation:
The line y = x + 3 passes through the point (0, 3) on the yaxis.
Find the perpendicular line passing through this point:
y - 3 = -1(x + 0)
y = -x + 3
Now find the point where this line intersects the line y = x + 1:
y = -x + 3
y = x + 1
-x + 3 = x + 1
3 -1 = x + x
2x = 2
x = 1
and y = 2
So this point is (1, 2)
We require the distance between this point and (0, 3)

Probability (A heart or a jack) = 13 + 3 / 52Probability (A heart or a jack) = 16/52Probability (A heart or a jack) = 4/13(c)

Department A occupies 1400 m2, Department B occupies 820 m², Department C occupies 560 m2, and Department D occupies 390 m². If the cost of operating for March was $19 000. how much of the cost should each department of the Marketing Department take up?
The cost of each department A, B, C, and D of the Marketing Department would take up is $8,391.17, $4,914.83, $3,356.47, and $2,337.53, respectively.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Given the cost of operating the marketing Department for March is $19,000. The total area of operation is,
Total Area = Department A + Department B + Department C + Department D
Total Area = 1400 m² + 820 m² + 560 m² + 390 m² = 3,170 m²
Now, the cost of operating a unit area can be determined as,
Cost of operating = $19,000/3,170m² = $5.99369 per m²
Further the cost of operating the different departments are,
Department A = 1400m²×$5.99 = $8,391.17
Department B = 820m²×$5.99 = $4,914.83
Department C = 560m²×$5.99 = $3,356.47
Department D = 390m² × $5.99 = $2,337.53
Hence, the cost of each department A, B, C, and D of the Marketing Department would take up is $8,391.17, $4,914.83, $3,356.47, and $2,337.53, respectively.
