Answer:

x = 240

A = 30 m, B = 60 m, C= 90 m

Step-by-step explanation:

a) Nosotros debemos determinar un numero;

para cual \(\dfrac{1}{4}x = 60\)

\(0.25 x = 60\)

Divide ambos lados entre 0.25; tenemos :

\(\dfrac{0.25 x}{0.25}= \dfrac{60}{0.25}\)

x = 240

b) A 180 m se corta en tres piezas A, B y C

Entonces;

Si la pieza B y la pieza C miden el doble y el triple de esa pieza A, respectivamente. Entonces; tenemos

x + 2x + 3x = 180

6x = 180

Divide ambos lados entre 6; tenemos:

\(\dfrac{6x}{6} = \dfrac{180}{6}\)

x = 30 m

Si A = x = 30 m

B = 2x = 2×30 m = 60 m

C = 3x = 3×30 m = 90 m

Así; A = 30 m, B = 60 m, C= 90 m

The solution is, Our required inequality would be (8x - 4) > 16.

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

Let the number be 'x'.

Eight times a number is expressed as

8x

Sum of eight times a number and negative four is expressed as

8x - 4

the above exceeds 16 is expressed as

8x - 4 > 16

Hence, our required inequality would be (8x - 4) > 16

The equation for distance of the flowerbed from the hive.

(d/10)+(d/6) = 240

The distance of  the flowerbed from the​ hive = 900ft

To calculate speed, divide the journey's distance by the time it took to travel, so speed = distance divided by time. Divide the distance by the speed to get the time. Multiply speed by time to find the distance. These equations can be simplified to s=d/t, where s represents speed, d is distance, and t is time.

Let the distance of flower bed from hive to be = d

Time the bee stays at the flower bed = 11

Time the bee is away from the hive = 15

Time the bed was flying to the flower bed and back to the hive will be;

15 -11=4 minutes--------------changes to seconds by multiplying by 60

=4*60

=240 seconds

Formular for time is Distance/speed

Time of fright=240 seconds

Form expression for time of flying;

Time for flying from hive to flowerbed= d/10ft/s

Time for flying from flower bed to Hive= d/6ft/s

Solving these two equation we get:

A. (d/10)+(d/6) = 240

B. distance of  the flowerbed from the​ hive:

(8d/30) = 240

8d = 7200

d = 7200/8

The proof of AD/DC = AB/CB is given below.

Given that;

Line BD bisects ∠ABC.

Now: Auxiliary Line EA is drawn such that Line AE is parallel to Line BD . Auxiliary Line BE is an extension of Line BC.

Since, Lines EA and BD are parallel,

∠1 = ∠ 4  (Corresponding angles)

So, We get;

∠2 = ∠ 3 (Alternate angles)

∠1 = ∠ 3 (because it is given that BD bisects ∠ABC )

So, by the above three equations, we get

∠ 2= ∠ 4

So, BE=AB (Opposite sides equal to opposite angles are equal)

    .........Equation 1)

Now, consider triangle ACE,

Since AE is parallel to BD.

By Basic Proportionality theorem, which states

" If a line is drawn parallel to one side of a triangle intersecting other two sides, then it divides the two sides in the same ratio."

So, we get

AD/DC = BE/CB

By using equation 1, we get

AD/DC = AB/CB

Hence, It can be proved.

A correlation coefficient of -1.0 between two sets of numbers that when one set of numbers goes up, the other set goes down; a complete lack of any correlation between the two sets. The correct answer is d)

The correlation coefficient measures the strength and direction of the linear relationship between two sets of numbers. It ranges from -1 to +1, where -1 indicates a perfect negative correlation, +1 indicates a perfect positive correlation, and 0 indicates no linear correlation.

When the correlation coefficient is -1.0, it signifies a perfect negative correlation. This means that when one set of numbers increases, the other set decreases in a perfectly linear fashion. As the value of one set of numbers increases, the value of the other set decreases in a proportional manner.

Therefore, option d) is the correct answer, as it accurately describes the behavior exhibited by a correlation coefficient of -1.0. It indicates a complete lack of any correlation between the two sets, with one set going up while the other set goes down in a perfectly linear relationship.

The probability that the proportion of overweight or obese children in the sample will be greater than 0.57 is less than 50%.

The first paragraph summarizes the answer, stating that the probability is less than 50% because 0.57 is less than the population proportion of 0.60, and the sampling distribution is approximately normal.

In the second paragraph, we can explain the reasoning behind this conclusion. The Central Limit Theorem states that for a large sample size, the sampling distribution of the sample proportion will be approximately normal, regardless of the shape of the population distribution. In this case, the sample was taken in a way that meets the conditions for using the Central Limit Theorem.

Since the population proportion of overweight or obese children is 0.60, any sample proportion below this value is more likely to occur. Therefore, the probability of obtaining a sample proportion greater than 0.57 would be less than 50%. This is because the resulting z-score, which measures how many standard deviations the sample proportion is away from the population proportion, would be negative.

To summarize, the probability of the proportion of overweight or obese children in the sample being greater than 0.57 is less than 50% because 0.57 is less than the population proportion of 0.60, and the sampling distribution is approximately normal.

Answer:

X=4 Y=28

Step-by-step explanation:

We have our two equations, 2x+4=12 and Y=4x+12
Solve for x of one of the equations so that the repeating (common) variable can be cancelled out.

Using 2x+4=12, we can solve for the x-value and replace it back into y.

2x+4=12
2x=8
x=4

We can replace our new x-value into the other equation, y=4x+12

y=4(4)+12
y=16+12
y=28

So x=4, and y=28

Question 10: No Question 11: 45 degrees Question 12: 13.03 units (rounded to the hundredths)

Question 10: No, the angles 99 degrees and 459 degrees are not coterminal. Coterminal angles have the same initial and terminal sides, which means their difference should be a multiple of 360 degrees. In this case, 459 - 99 = 360, so they are not coterminal. Question 11: To find the angle that subtends an arc of length 2 feet on a circle with a radius of 8 feet, you can use the formula: Angle (in radians) = Arc length / Radius First, convert the angle from radians to degrees by multiplying it by (180 / π). Therefore: Angle (in degrees) = (2 / 8) * (180 / π) ≈ 28.65 degrees Question 12: To find the length of the arc that subtends a central angle of 124 degrees on a circle with a radius of 6, you can use the formula: Arc length = (Central angle in radians) * Radius First, convert the central angle from degrees to radians by multiplying it by (π / 180). Therefore: Arc length = (124 * (π / 180)) * 6 ≈ 14.36 (rounded to the hundredths)

Step-by-step explanation:

The slope of the line r is 3 and the y intercept is (0,15) .

We know that coordinates of the point (x,y) after dilation by factor k centered at (a,b) is  (k(x-a) + a , k(y-b) + b)  .

In the question ,

it is given that

the slope of the line p \(=\) 3

and the intercept of the line p = (0,2)

So , the equation of the line p is y = 3x + 2 .

So , the coordinates of the point (0,2) after dilation by factor 3 centered at (0,0) is (3(0 - 0) + 0 , 3(5 - 0) + 0)

= (0 , 15)

Point (0,0) does not lie on the line, so the line r after dilation is parallel to the line p,

the slope of line r = 3 , the y intercept is 15 .

Therefore , The slope of the line r is 3 and the y intercept is (0,15) .

The given question is incomplete , the complete question is

In the coordinate plane, line p has slope 3 and y-intercept (0, 2). Line r is the result of dilating line p by a factor of 3 centered at the origin. What are the slope and y-intercept of line r ?
