Answer:

The student answer is wrong. The correct length of the hypotenuse is 12

Step-by-step explanation:

The question is incomplete without diagram. Find the diagram attached below.

The longest side of the right angled triangle is the hypotenuse.

The side facing the angle 30° is the opposite side of the triangle.

To find the hypotenuse, we will use the SOH CAH TOA method in trigonometry identity.

According to SOH:

Sin30° = Opposite/Hypoenuse

Sin30° = 6/Hypotenuse

Hypotenuse = 6/sin30°

Hypotenuse = 6/0.5

Hypotenuse = 6×2

Hypotenuse = 12

The student answer is wrong. The correct length of the hypotenuse is 12

Answer:

The confidence level of the study is 99.9%

The confidence level is 99.9% of the margin error is 8%

Step-by-step explanation:

Explanation:-

Candy has observed 250 sports cars

The sample size 'n' = 250

Sample proportion 'p' = 15% = 0.15

The margin of error = 8% = 0.08

The margin of error  is determined by   = [tex]\frac{z_{\alpha }\sqrt{p(1-p)} }{\sqrt{n} }[/tex]

                                                 [tex]0.08 X \sqrt{250} = z_{\alpha } \sqrt{0.15 (1-0.15)}[/tex]

                                                    [tex]\frac{ 0.08 X \sqrt{250}}{ \sqrt{0.15 (1-0.15)}} = z_{\alpha }[/tex]

                                                    [tex]z_{\alpha }= \frac{ 0.08 X \sqrt{250}}{ \sqrt{0.15 (1-0.15)}} = \frac{1.2649}{0.35707}[/tex]

                                                    [tex]z_{\alpha } = 3.5431[/tex]

Conclusion:-

The z- score of 99.9% level of significance = 3.54 for two tailed test

Hence the confidence level is 99.9% of the margin error is 8%.

Final answer:

The percentage increase in the perimeter of the rectangle is 6%.

Explanation:

To find the percentage increase in the perimeter of the rectangle, we need to calculate the new perimeter and compare it to the original perimeter.

The original length is 20 and the width is 30. The original perimeter is 2(20+30) = 100.

When the length is increased by 10%, it becomes 20 + 10% of 20 = 20 + 2 = 22. The width is increased by 5%, so it becomes 30 + 5% of 30 = 30 + 1.5 = 31.5.

The new perimeter is 2(22+31.5) = 106. The percentage increase in the perimeter is (106-100)/100 * 100 = 6%.

The surface area is 294 ft^2 (please give branliest)

Step-by-step explanation:

area of one side 49

multiply by 6 sides

The surface area of the cube is equal to 294 square inches.

How to calculate the surface area of the cube

In this problem we find the representation of a cube, whose surface area, that is, the sum of the areas of all faces of the cube, must be computed in accordance with this formula:

A = 6 · l²

Where:

If we know that l = 7 in, then the surface area of the cube is equal to:

A = 6 · (7 in)²

A = 6 · 49 in²

A = 294 in²

The cube has a surface area of 294 square inches.

Answer:

Here we have the table for the 8 students that said yes.

a) Out of the 8 students, 5 purchased their favorite food more than four times a month.

The proportion will be p = 5/8, and this can not be simplified anymore because 5 is a prime number and 5 is not a factor of 8.

b) The mean time will be equal to the amount of each of the 8 purchased their favourite food divided by the total sample (8)

This is:

m = (6 + 4 + 3 + 8 +6 + 9 + 4 + 7)/8 = 5.875

c) Out of a sample of 20, 8 buy lunch regularly, this is; p1 = 8/20

The amount of students that regularly buy food will be:

p1*1000 = (8/20)*1000 = 400

And of those 400, 5/8 buy their favourite lunch more than 4 times per month:

(5/8)*400 = 250

d: The mean number of times that a student regularly buys salad.

We have 3 students that regularly buy salad (so we only do the math with those 3)

The mean is (8 + 6 + 7)/3 = 7

So for the students that regularly buy salad, the mean of times that the buy salad in a month is 7 times.

The instantaneous velocity of the baseball 3 seconds after it is hit is [tex]\( 24 \)[/tex] feet per second.

To find the instantaneous velocity of the baseball 1 second and 3 seconds after it is hit, we need to differentiate the height function [tex]\( s(t) \)[/tex] with respect to time [tex]\( t \)[/tex] to get the velocity function [tex]\( v(t) \).[/tex]

The height function is given by:

[tex]\[ s(t) = -16t^2 + 88t + 4 \][/tex]

1. Find the Velocity Function:

[tex]\[ v(t) = s'(t) \][/tex]

Differentiate [tex]\( s(t) \)[/tex] with respect to [tex]\( t \)[/tex]:

[tex]\[ v(t) = -32t + 88 \][/tex]

2. Evaluate the Instantaneous Velocity at [tex]\( t = 1 \)[/tex] second:

[tex]\[ v(1) = -32(1) + 88 = 56 \][/tex]

The instantaneous velocity of the baseball 1 second after it is hit is [tex]\( 56 \)[/tex] feet per second.

3. Evaluate the Instantaneous Velocity at [tex]\( t = 3 \)[/tex] seconds:

[tex]\[ v(3) = -32(3) + 88 = 24 \][/tex]

The answer is [tex]\( 24 \)[/tex] feet per second.

So, after differentiating the height function to get the velocity function, we substituted the given values of time [tex](\( t = 1 \)[/tex] and [tex]\( t = 3 \))[/tex] into the velocity function to find the corresponding instantaneous velocities.

The instantaneous velocity provides information about the speed and direction of the baseball at a specific moment in time. In this case, 1 second after being hit, the baseball is moving upward with an instantaneous velocity of [tex]\( 56 \)[/tex] feet per second, and 3 seconds after being hit, it is still moving upward but with a reduced instantaneous velocity of[tex]\( 24 \)[/tex] feet per second.

The complete question is given here :

A foul tip of a baseball is hit straight upward from a height of 4 feet with an initial velocity of 88 feet per second. The function [tex]s(t) = -16t^2 + 88t + 4[/tex] describes the ball's height above the ground, s(t), in feet, t seconds after it was hit. What is the instantaneous velocity of the ball 1 second after it is hit? 3 seconds after it is hit?

To solve for x when g(x) = 9 given the function g(x) = -x – 4, set the equations equal to each other. Rearrange the equation and solve for x, which gives x = -13

The question asked for the value of x when g(x) = 9 given the function g(x) = -x – 4. We can start by setting the two equations equal to each other. This gives us -x - 4 = 9. Next, we rearrange the equation to solve for x by adding 4 to each side, which gives us -x = 9 + 4 or -x = 13. To get x on its own, we divide each side by -1. This gives us x = -13. Therefore, when g(x) = 9, x is equal to -13.

Answer:

67,500 residents

Step-by-step explanation:

The population density is defined as the average number of people living per square unit area.

-Given the density is 225res/sq mile and the area is 300 sq mile, the area's population is:

[tex]\rho=\frac{Population}{Area}\\\\Population=Area \times \rho\\\\=300 \ mi^2\times 225\ res/mi^2\\\\=67500\ residents[/tex]

Hence, there are 67,500 residents in Flint county.

To calculate the population of Flint County, the population density (225 residents/mile2) is multiplied by its area (300 mile2), resulting in a population of 67,500 residents.

To find the population of Flint County, we need to multiply the population density by the area of the county. The population density is given as 225 residents per square mile, and the area of Flint County is 300 square miles. By multiplying these two values together, we can determine the total population.

Population of Flint County = Population Density × Area = 225 residents/mile2 × 300 mile2

Population of Flint County = 225 × 300 = 67,500 residents

Therefore, the population of Flint County is 67,500 residents.

The median is [tex]\(55\)[/tex], Q1 is approximately [tex]\(19.5\)[/tex], Q3 is [tex]\(79\)[/tex], and the interquartile range is [tex]\(59.5\).[/tex]

To find the median, first quartile (Q1), third quartile (Q3), and interquartile range (IQR) for the given set of numbers, you first need to arrange them in ascending order:

[tex]\[ 14, 25, 28, 38, 55, 66, 92, 94, 97 \][/tex]

Now, let's find each of the required values:

1. **Median (Q2)**: The median is the middle value of the dataset when arranged in ascending order. Since there are 9 numbers, the median will be the value at the [tex]\(\frac{9+1}{2} = 5\)[/tex]-th position, which is the 5th number in the sorted list: [tex]\(55\)[/tex].

2. **First Quartile (Q1)**: Q1 is the median of the lower half of the dataset. Since there are an odd number of data points in the lower half (4 points), Q1 will be the median of the first four numbers: [tex]\( \frac{14 + 25}{2} = 19.5 \).[/tex]

3. **Third Quartile (Q3)**: Q3 is the median of the upper half of the dataset. Similarly, since there are an odd number of data points in the upper half (also 4 points), Q3 will be the median of the last four numbers: [tex]\( \frac{66 + 92}{2} = 79 \).[/tex]

4. **Interquartile Range (IQR)**: IQR is the difference between Q3 and Q1. So, [tex]\( IQR = Q3 - Q1 = 79 - 19.5 = 59.5 \).[/tex]

So, the median is [tex]\(55\)[/tex], Q1 is approximately [tex]\(19.5\)[/tex], Q3 is [tex]\(79\)[/tex], and the interquartile range is [tex]\(59.5\).[/tex]

To convert the tree's circumference from inches to centimeters, multiply 17 inches by the conversion factor of 2.54 cm per inch, resulting in 43.18 cm, which is not an exact match to the provided options but the closest option is 42.5 cm.

Explanation:

To convert James' measurement of the tree's circumference from inches to centimeters, we use the conversion factor that 1 inch equals 2.54 centimeters. Therefore, if the tree's circumference is 17 inches, we multiply 17 by 2.54 to get the circumference in centimeters.

The calculation is as follows:

Multiply the circumference in inches (17 inches) by the conversion factor (2.54 cm per inch).

The result is 17 inches × 2.54 cm/inch = 43.18 cm.

Therefore, the tree's circumference in centimeters is 43.18 cm, which rounds down to 43 cm when measuring to the nearest whole number, none of the options exactly match but option A is the closest. So, we must choose the closest option, which is A. 42.5 cm.
