Option B is the correct answer, as it correctly states that the first quartile value of fish lengths at Lake Palmer is 1.25 inches longer than that of Lake Dalton.
Explanation:The question provides quartile data for fish lengths caught in two different lakes and asks to generalize the findings based on the provided information. First, let's analyze the provided options:
Option B: Incorrect, because the difference between the first quartiles of Lake Palmer (6.75 inches) and Lake Dalton (5.5 inches) is 1.25 inches, hence true.Option C: Incorrect, because the interquartile range (IQR) for Lake Dalton (7.5 - 5.5 = 2 inches) is not 2 inches greater than the IQR for Lake Palmer (13 - 6.75 = 6.25 inches).Option D: Incorrect because at least 25 percent of the fish in Lake Dalton are no longer than 5.5 inches, and at least 25 percent of the fish in Lake Palmer are no longer than 6.75 inches. Hence, not all fish in both lakes are no longer than 6 inches.Therefore, the correct generalization can be made from Option B. It provides accurate comparison based on the first quartile values of fish lengths in both lakes.

For the firs one draw a dot where they start. Then draw a line going down and label it 10. Next draw a line going left and label it 24. Connect the end of those who lines to form a triangle. Now we can use the pythagorean theory.
a^2 + b^2 = c^2
a^2= side one (you choose)
b^2= side two (whichever side you didn't use out of the two)
c^2= the hypotenuse( this is the diagonal line you drew connecting the two lines at the end)

Determine the compound interest earned on $200 invested at 3.25% compound annually for 6 years
Answer:
$882.24 compound interest earned / $1,082.24 total
Step-by-step explanation:
You are going to want to use the compound interest formula, which is shown below.
[tex]P(1+\frac{r}{n} )^{nt}[/tex]
P = initial balance
r = interest rate
n = number of times compounded annually
t = time
Now lets plug in the values into the equation.
[tex]200(1+\frac{.325}{1} )^{6}[/tex] = 1,082.24
Since we want to know the compound interest earned, just subtract 200 from 1,082.24.
1,082.24 - 200 = $882.24

Annita is sewing a lace edge around a rectangular quilt. She will need 150 inches of lace to do the entire quilt. If the quiltis 42
inches wide, how long is the quilt?
A. 75 inches
B. 66 inches
C. 31 inches
D. 33 inches
With a total perimeter of 150 inches and a width of 42 inches, the length was calculated to be 33 inches, option D.
To determine how long the quilt is, we need to calculate the perimeter of the rectangular quilt and then solve for the missing length. Since Annita needs 150 inches of lace, we know this is the total perimeter (P) of the quilt. The quilt is 42 inches wide. The formula for the perimeter of a rectangle is P = 2(length) + 2(width). We can set up the equation as 150 = 2(length) + 2(42).
Now let's solve for the length (L):
150 = 2L + 84 (since 2(42) is 84)150 - 84 = 2L66 = 2LL = 33 inchesThe length of the quilt is 33 inches, which corresponds to option D.
The length of the quilt is 33 inches.
The correct option is (D).
To find the length of the quilt, we need to use the formula for the perimeter of a rectangle, which is given by:
[tex]\[ \text{Perimeter} = 2 \times (\text{Length} + \text{Width}) \][/tex]
Given that the width of the quilt is 42 inches and Annita needs 150 inches of lace to go around the entire quilt, we can set up the equation as:
[tex]\[ 150 = 2 \times (\text{Length} + 42) \][/tex]
Now, let's solve for the length [tex](\( \text{Length} \)):[/tex]
[tex]\[ 150 = 2 \times (\text{Length} + 42) \][/tex]
[tex]\[ 75 = \text{Length} + 42 \][/tex]
Subtract 42 from both sides:
[tex]\[ 75 - 42 = \text{Length} \][/tex]
[tex]\[ \text{Length} = 33 \][/tex]
So, the length of the quilt is 33 inches. Therefore, the answer is option D. 33 inches.

Step-by-step explanation:
for anyone who didnt know 0.25 is equivalent to 1/4 just to make it clear 1/4 IS the correct answer saltyspark just put it in decimal form.
To find Ilana's average speed, we divide the total laps by the total minutes, which results in one-fourth of a lap per minute.
Explanation:To find the average speed, we divide the total distance by the total time taken
To determine Ilana's average speed, we need to divide the total distance (2 laps) by the total time (8 minutes). When we do that, we get 0.25 laps per minute.
This is also known as one-fourth of a lap per minute. That means, on average, Ilana completes a quarter of a lap every minute.

Step-by-step explanation:
A pool table is 8 feet long and 4 feet wide. How far is it from one corner pocket to the diagonally opposite corner pocket?
Using the Pythagorean theorem, the diagonal distance from one corner pocket to the diagonally opposite corner pocket on an 8 foot by 4 foot pool table is about 8.94 feet.
To determine the distance from one corner pocket to the diagonally opposite corner pocket on a pool table, we can use the Pythagorean theorem because the pool table forms a rectangle and the diagonal forms a right triangle with the length and width of the table. Given the dimensions of the pool table as 8 feet long and 4 feet wide, we can label these as the two sides of the right triangle.
The Pythagorean theorem states that for a right triangle with sides of lengths a, b, and hypotenuse c, the relationship between these sides is [tex]a^2 + b^2 = c^2[/tex]. Substituting the given values, we have:
Let's denote the length (8 feet) as a and the width (4 feet) as b.Using the theorem, we calculate the hypotenuse c as [tex]\sqrt{(8^2 + 4^2)}.[/tex]Compute the square of each side: [tex]8^2[/tex] = 64 and [tex]4^2[/tex] = 16.Add these together: 64 + 16 = 80.The hypotenuse (diagonal) c is the square root of 80, which simplifies to 4 [tex]\sqrt(5)[/tex] feet or approximately 8.94 feet.Therefore, the diagonal distance from one corner pocket to the diagonally opposite corner pocket is about 8.94 feet.

What is Parabola?A parabola is a U-shaped curve this is drawn for a quadratic function,
f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.
Given function, y = 3x²+7x+2
Compare the given function to f(x) = ax² + b x + c ,
The graph of given function is upward (or opens up) because the value of 3 is more than 0, 3 > 0.
The x-intercept of given function are (-1/3, 0) and (-2,0)
The y-intercept of given function is (0,2)
Here is a graph represents function of y = 3x²+7x+2

#SPJ5
The correct option is A. Graph A. It shows an upward-opening parabola with a vertex and y-intercept that match the derived values.
1. Direction of the Parabola : Since the coefficient of [tex]\( x^2 \)[/tex] (which is [tex]3[/tex]) is positive, the parabola opens upwards.
2. Vertex : The vertex of a parabola in the form [tex]\( y = ax^2 + bx + c \)[/tex] can be found using the formula for the x-coordinate of the vertex, [tex]\( x = -\frac{b}{2a} \)[/tex]
For the given function:
[tex]\[ a = 3, \quad b = 7 \][/tex]
So,
[tex]\[ x = -\frac{7}{2 \times 3} = -\frac{7}{6} \][/tex]
Next, we find the y-coordinate of the vertex by plugging [tex]\( x = -\frac{7}{6} \)[/tex] back into the equation:
[tex]\[ y = 3\left(-\frac{7}{6}\right)^2 + 7\left(-\frac{7}{6}\right) + 2 \][/tex]
Let's compute that:
[tex]\[ y = 3 \times \frac{49}{36} - \frac{49}{6} + 2 \][/tex]
[tex]\[ y = \frac{147}{36} - \frac{294}{36} + \frac{72}{36} \][/tex]
[tex]\[ y = \frac{147 - 294 + 72}{36} \][/tex]
[tex]\[ y = \frac{-75}{36} \][/tex]
[tex]\[ y = -\frac{25}{12} = -2.083 \][/tex]
Thus, the vertex is approximately at [tex]\(\left( -\frac{7}{6}, -\frac{25}{12} \right)\)[/tex]
3. Y-Intercept : This is the value of [tex]\( y \)[/tex] when [tex]\( x = 0 \)[/tex]
[tex]\[ y = 3(0)^2 + 7(0) + 2 = 2 \][/tex]
The graph should cross the y-axis at [tex]\( y = 2 \)[/tex]
Now, let's compare these features with the provided graphs:
The parabola should open upwards.
The y-intercept should be [tex]2[/tex].
The vertex should be approximately at [tex]\( \left( -\frac{7}{6}, -\frac{25}{12} \right) \)[/tex]

Mrs. Alexander wants to make a rectangular quilt that will have an area of 80 square feet So far, she has made 16
squares for the quilt each 2 feet long and 2 feet wide. Does she have enough squares to complete the quilt?
No, she doesn't have enough square to complete the quilt. Mrs. Alexander need 4 more squares to complete the rectangular quilt, that will have an area of 80 square feet. 20 square required to make quilt.
Step-by-step explanation:
The given is,
Area of an rectangular quilt - 80 square feet
She made 16 squares
Square have 2 feet long and 2 feet wide
Step:1
Area of rectangular quilt = 80 square feet
Area of 16 squares = 16 × Area of square..................(1)
Formula for area of square,
[tex]A = a^{2}[/tex]................................(2)
Where, a - Sides of square
a = Length = Wide
From given,
a = 2 feet
Equation (2) becomes,
[tex]A = 2^{2}[/tex]
A = 4 square feet
Equation (1) becomes,
Area of 16 squares = 16 × 4
= 64 square meters
Area of rectangular quilt ≠ Area of 16 squares
80 ≠ 64
Area of square is less compare to area rectangular quilt, so we need more square,
Required amount of square area = 80 - 64
= 16 square feet
Required amount of squares = [tex]\frac{16}{4}[/tex]
= 4 squares
Total(16+4) square areas = 20 × 4 = 80 square feet
Area of rectangular quilt = Area of 20 squares
80 square feet = 80 square feet
Result:
No, she doesn't have enough square to complete the quilt. Mrs. Alexander need 4 more squares to complete the rectangular quilt, that will have an area of 80 square feet. 20 square required to make quilt.
