The proportion of people who were caught after being on the 10 Most Wanted list is 0.259.

Step-by-step explanation:

Proportion of people who were caught after being on the 10 Most Wanted list.

Number of people caught divided by the size of the sample.

In this question:

377 people caught.

1453 suspected criminals.

Then

\(p = \frac{377}{1453} = 0.259\)

The proportion of people who were caught after being on the 10 Most Wanted list is 0.259.

The value of x in the triangles are 9.

For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.

Given:

The triangles are congruent.

That means, their corresponding angles are also congruent.

In ΔJKL,

the sum of all the angles of the triangle is 180°.

So,

x²-2x + x + 29 + 3x + 52 = 180

x² + 2x - 99 = 0

Solving the quadratic equation,

x² +11x - 9x - 99 = 0.

x (x + 11) -9 (x + 11) = 0

x = 9 and x = -11

Here, we take x = 9.

Therefore, the value of x is 9.

Let, number of children and adults swam at the public pool that day is x and y.

So, x + y = 379   .....1)

It is given that daily prices are $1.75 for children and $2.00 for adults.

Also, the  receipts for admission totaled $693.50.

So, 1.75x + 2y = 693.50  .....2)

Putting value of y from equation 1 to equation 2 , we get :

1.75x + 2( 379 - x ) = 693.50

758 - 2x + 1.75x = 693.50

0.25x = 64.5

x = 258

So, y = 379 - 258 = 121

Therefore, number of children are 258 and adults are 121.

Considering the definition of an equation and the way to solve it, the smallest four integers are 8, 10, 12, 14.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values appear.

The members of an equation are each of the expressions that appear on both sides of the equal sign.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

Being "x" n any integer, and knowing that:

So, the equation in this case is:

(2n + 2n +2 + 2n +4 + 2n + 6)÷ 4= 11

Solving:

(8n +12)÷ 4=11

8n +12= 11× 4

8n +12= 44

8n= 44 -12

8n= 32

n= 32 ÷ 8

n= 4

Then, the smallest four integers can be calculated as:

Finally, the smallest four integers are 8, 10, 12, 14.

Step-by-step explanation:

It seems that the problem solved incorrectly is the one represented by letter A, which is trying to find the missing angle in a triangle. The correct answer is 74.1°, which can be obtained by subtracting the sum of the other two given angles (83.2° and 22.7°) from 180°.

The problem that Anna solved incorrectly is the last one: 32 + x = 108. The correct answer should be x = 76, not x = 108.

In this math problem, Anna seems to be solving for unknown angles in several triangle problems. An important principle here is that the sum of the angles in a triangle always adds up to 180 degrees. Looking at the problems she solved:

Answer:

∠CED is a right angle.

∠CEA is a right angle.

m∠CEB = m∠BEA

m∠DEB = 135°

Answer:

Step-by-step explanation:

If the sum of two angles = 180°

Then the pair of angles will be supplementary.

If the sum of two angles = 90°

Then the pair of angles will be complementary.

Sum of angles having measures 98° and 82° = 98° + 82°

                                                                          = 180°

Therefore, both the angles will be supplementary.

Sum of angles having measures 134° and 36° = 134° + 36°

                                                                            = 170°

Therefore, these angles are neither supplementary nor complementary.

d)a bag that contains 1475 chocolate chips is at the 95.82th percentile rank (or the top 4.18% of all bags).

what is probability?

Probability means measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that it is certain. If  event has  probability of 0.5

what is proportion?

Proportion refers to the relative size or amount of one quantity compared to another. It is a ratio of the part to the whole. For example, if there are 10 red balls and 30 balls in total, then the proportion of red balls is 10/30 or 1/3.

In the given question,

(a)  probability that a randomly selected bag contains between 1000 and 1500 chocolate chips, we need to calculate the area under the normal curve between z-scores of -1.02 and 1.16, where:

z1 = (1000 - 1252) / 129 = -1.02

z2 = (1500 - 1252) / 129 = 1.16

Using a standard normal table or calculator, we can find that the area under the curve between z=-1.02 and z=1.16 is approximately 0.7745. Therefore, the probability that a randomly selected bag contains between 1000 and 1500 chocolate chips is 0.7745 or 77.45%.

(b) To find the probability that a randomly selected bag contains fewer than 1050 chocolate chips, we need to calculate the area under the normal curve to the left of z-score of:

z-scores = (1050 - 1252) / 129 = -1.71

Using a standard normal table or calculator, we can find that the area under the curve to the left of z=-1.71 is approximately 0.0436. Therefore,

(c) To find the proportion of bags that contains more than 1200 chocolate chips, we need to calculate the area under the normal curve to the right of z-score of:

z = (1200 - 1252) / 129 = -0.40

Using a standard normal table or calculator, we can find that the area under the curve to the right of z=-0.40 is approximately 0.3446. Therefore, the proportion of bags that contains more than 1200 chocolate chips is 0.3446 or 34.46%.

(d) To find the percentile rank of a bag that contains 1475 chocolate chips, we need to calculate the area under the normal curve to the left of the corresponding z-score.

z = (1475 - 1252) / 129 = 1.73

Using a standard normal table or calculator, we can find that the area under the curve to the left of z=1.73 is approximately 0.9582. Therefore, a bag that contains 1475 chocolate chips is at the 95.82th percentile rank (or the top 4.18% of all bags).

Answer:

From the question, we have the following parameters that can be used in our computation:

sin 5pi/12

Express properly

So, we have

sin(5π/12)

Convert the angle to degrees

This gives

sin(5π/12) = sin(5/12 * 180)

Evaluate

sin(5π/12) = sin(75)

The actual value of sin(75) is (√6 + √2)/4

This means that

sin(5π/12) = (√6 + √2)/4

The exact value of sin 5π/12 is (√6 + √2)/4

The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

Angle in trigonometry can be measured in either degree or radian.

π is a measurement in radian which is equivalent to 180° in degrees.

Therefore:

5π/12 = 5 × 180/12

= 75°

Therefore sin5π/12 = sin75°

sin75 = sin( 45+30) = sin45cos30+ cos 45sin30

= 1/√2 × √3/2 + 1/√2 × 1/2

= √3/2√2 + 1/2√2

= (√3+1)/2√2

You have proven that the triangles are congruent because you used the shortcut by proving a side and angle and a side are congruent so SAS makes them congruent

According to the figure the required lengths are

BD = 7 units

BC = 9.9 units

The required lengths is solved knowing that in a right triangle having angle 45 degrees, the lengths of the legs of the right triangle are equal.

Also,  the perpendicular bisector creates another angle 45 degrees at angle B.

hence we another right triangle with a leg as 7 units hence BD is 7 units

solving for BC

BC = BA

BC² + BA² = CA²

BC² + BC² = 14²

2 x BC² = 196

BC² = 98

BC = √(98)
