Answer:

102

Step-by-step explanation:

Since we know that the numbers are two consecutive even numbers, we can write an equation like this where n represents the 2 numbers.

n + (n+2) = 206

Simplify the left side:

n + (n+2) = 206 -----> 2n+2 = 206

Subtract 2 from both sides:

2n = 206-2 -----> 2n = 204

Now divide 204 by 2:

n = 204/2 -----> n = 102

The smallest of two consecutive even numbers, whose sum is 206, is 102.

The question is asking for the smallest of two consecutive even numbers whose sum is 206. Let’s denote the smaller even number by n. The next consecutive even number would be n+2 (since even numbers are two units apart).

The problem states that the sum of these two numbers is 206 which can be written in the equation form as n + (n+2) = 206. It simplifies to 2n + 2 = 206. Subtracting 2 from both sides, we get 2n = 204. And finally, dividing by 2, we find that n = 102. So, the smallest number is 102.

Answer:

In a sequence of 5 numbers, the 3rd number is the middle number. So in your problem the third number is the average of the 5 numbers -- which is the sum of the numbers, divided by how many there are: 505/5 = 101.

Explanation:

The 5 numbers will be: 97, 99, 101, 103 and 105

Let the 5 consecutive numbers be x-4, x-2, x, x+2 and x+4.

Now it is given that the sum of the 5 numbers is 505. This can be represented mathematically as follows:

[tex](x-4)+(x-2)+x+(x+2)+(x+4) = 505\\\\5x = 505\\\\x= 101[/tex]

So, x - 4 = 97

x - 2 = 99

x + 2 = 101

x + 4 = 103

Thus, the 5 numbers will be: 97, 99, 101, 103 and 105

Answer:

the mean is equal to the median

Step-by-step explanation:

From the bar graph,

The mean is equal to the median.

Option B is the correct answer.

A bar graph is a type of chart used to represent data using rectangular bars, where the length or height of each bar corresponds to the value of the data.

The bars can be arranged horizontally or vertically and are usually separated by equal spaces.

The x-axis represents the categories or groups being compared, and the y-axis represents the scale or measurement of the data being shown.

We have,

For a graph that is perfectly symmetric, the mean and median are equal.

In the given bar graph, the bars are perfectly symmetric around the middle bar, which is bar 5.

This means that the median value of the data represented by the graph is 5.

To find the mean of the data, we can add up the heights of all the bars and divide by the total number of bars:

(2 + 4 + 6 + 8 + 10 + 8 + 6 + 4 + 2) ÷ 9 = 6

So the mean value of the data is also 6.

Therefore,

The mean is equal to the median.

Step-by-step explanation:

The coordinates of the vertex A of square ABCD is (1, 6).

Translation is a type of transformation of geometrical figures. After translation, the original figure is shifted from a place to another place without affecting it's size.

Given that,

A square ABCD undergoes a translation of (-4, -1) and a rotation of 90° to form the square A''B''C''D''.

Let (x, y) be the coordinates of A.

After the translation of (-4, -1), it becomes,

A'(x - 4, y - 1)

When it rotates to 90°, it becomes,

A''(-(y - 1), x - 4) = A''(1 - y, x - 4) = (-5, -3)

1 - y = -5 ⇒ y = 1 + 5 = 6

x - 4 = -3 ⇒ x = 1

Coordinates are (1, 6)

Hence the coordinates of A is (1, 6).

Answer:

The 90% confidence interval for the proportion of married couples with three personality preferences in common compared  with the proportion of couples with two preferences in common is (-0.081, 0.025).

Step-by-step explanation:

The (1 - α)% confidence interval for difference in proportion formula is,

[tex]CI=(\hat p_{1}-\hat p_{2})\pm z_{\alpha/2}\sqrt{\frac{\hat p_{1}(1-\hat p_{1})}{n_{1}}+\frac{\hat p_{2}(1-\hat p_{2})}{n_{2}}}[/tex]

The given information is:

n₁ = 375,

n₂ = 571,

X₁ = 132,

X₂ = 217.

Compute the sample proportion as follows:

[tex]\hat p_{1}=\frac{X_{1}}{n_{1}}=\frac{132}{375}=0.352\\\\\hat p_{2}=\frac{X_{2}}{n_{2}}=\frac{217}{571}=0.38\\[/tex]

For the 90% confidence level, the z-value is,

z₀.₀₅ = 1.645

*Use a z-table.

Compute the 90% confidence interval for the difference in proportion as follows:

[tex]CI=(\hat p_{1}-\hat p_{2})\pm z_{\alpha/2}\sqrt{\frac{\hat p_{1}(1-\hat p_{1})}{n_{1}}+\frac{\hat p_{2}(1-\hat p_{2})}{n_{2}}}[/tex]

     [tex]=(0.352-0.38)\pm 1.645\sqrt{\frac{0.352(1-0.352)}{375}+\frac{0.38(1-0.38)}{571}}\\=-0.028\pm 0.05256\\=(-0.08056, 0.02456)\\\approx (-0.081, 0.025)[/tex]

The 90% confidence interval for the proportion of married couples with three personality preferences in common compared  with the proportion of couples with two preferences in common is (-0.081, 0.025).

This confidence interval implies that the true difference between the proportions lies in this interval with probability 0.90.

The 90% confidence interval for the difference in proportions of married couples with two and three personality preferences in common is (0.027, 0.089). This indicates that with 90% confidence, the proportion of couples with two preferences in common is significantly higher.

Firstly, we need to find the proportions for both samples. The proportion for three personality preferences in common is 132/375 = 0.352 and for two personality preferences in common is 217/571 = 0.380.

Next, to compute the standard error, we use the formula √[ P(1 - P) / n ]. For three personality preferences we get √[ 0.352(1 - 0.352) / 375] = 0.026. And for two personality preferences we obtain √[ 0.380(1 - 0.380) / 571] = 0.021.

From these, the difference in the two sample proportions can be calculated, which is 0.380 - 0.352 = 0.028. The standard error of the difference can then be calculated as √( 0.026 ^ 2 + 0.021 ^ 2) = 0.033. At the 90% confidence level, the z-score is 1.645.

To calculate the confidence interval, note that 0.028 ± 1.645 * 0.033 is the equation we are trying to solve. This produces a range from 0.027 to 0.089.

So, the 90% confidence interval for difference in proportions is (0.027, 0.089), meaning that with 90% confidence, the proportion of couples with two preferences in common is significantly higher than those couples with three personality preferences in common.

Final answer:

there were 7 horses and 8 chickens in the barn.

Explanation:

To represent the situation with a system of equations, let's assume that the number of horses is represented by 'h' and the number of chickens is represented by 'c'.

We know that there are a total of 15 animals, so we can write the equation: h + c = 15.

We also know that the total number of legs is 44, and since each horse has 4 legs and each chicken has 2 legs, we can write the equation: 4h + 2c = 44.

To solve this system of equations, we can use the method of substitution or elimination. Substituting h = 15 - c into the second equation, we get 4(15 - c) + 2c = 44. Simplify and solve for c to find the number of chickens, then substitute the value of c back into the first equation to find the number of horses.

Let's solve this system of equations:

h + c = 15

4h + 2c = 44

We can solve this using the method of substitution:

h = 15 - c

Substituting this into the second equation:

4(15 - c) + 2c = 44

60 - 4c + 2c = 44

-2c = 44 - 60

-2c = -16

c = -16/-2

c = 8

Substituting the value of c back into the first equation:

h + 8 = 15

h = 15 - 8

h = 7

So, there were 7 horses and 8 chickens in the barn.

Answer:

432π cm² or 1356.48 cm²

Step-by-step explanation:

The area of a circle is πr²

The area of the disks are 144π and 576π.

576π-144π = 432π

432π ≈ 1356.48 cm²

To find the difference in areas of two circles, calculate the area of each circle using the formula πr² and then subtract the smaller area from the larger one. For Alice's discs with diameters 12 cm and 24 cm, the areas are 36π and 144π square cm respectively, and their difference is 108π square cm.

To find the difference in the areas of Alice's two flying disks, first we need to calculate the area of each disk. The formula for the area of a circle (or disk) is πr², where r is the radius of the circle. The radius is half of the diameter, so for the first disk, the radius is 6 cm and for the second disk, the radius is 12 cm.

The area of the first disk is π*(6 cm)² = 36π square cm. The area of the second disk is π*(12 cm)² = 144π square cm. The difference between these two areas is 144π - 36π = 108π square cm.
