Evaluate j(k+2), when j=5 and k=3.

Relationships that have a uniform or constant rate are said to be proportional relationships. Because it does not employ a uniform rate, the price of food does not follow a proportional connection.

The missing table looks like this:

Bag     cost

0           0

5          17.5

30        89

First, we calculate the slope (m) of the table using:

(x₁ y₁) = (0,0)

(x₂ y₂) = (5,17.5)

m₁=(y₂-y₁)/(x₂ -x₁)

m₁=(17.5-0)/(5-0)

m₁=3.5

The slope for the following points

(x₁ y₁) = (0,0)

(x₂ y₂) = (30,89)

m₂=(y₂-y₁)/(x₂ -x₁)

m₂=(89-0)/(30-0)

m₂=2.97

3.5 ≠2.97

Hence, the cost of food is not a proportional relationship because it does not use a uniform rate.

The car has a value of $ 15 500 at the end of the fifth year.

In accordance with the statement, the value of an automobile decreases in time and decreases steadily. A stead decrease means that the value decreases linearly in time, whose formula is shown below:

C' = C + r · t         (1)

Where:

If we know that C = $ 2 600, C' = $ 37 000 and t = 8, then the value of the car at the end of the fifth is:

r = (C' - C) / t

r = (2 600 - 37 000) / 8

r = - 4 300

t = 5

y = 37 000 - 4 300 · 5

y = 15 500

Answer: 45

Step-by-step explanation:

The LCM of 5 and 9 is 45. To find the least common multiple of 5 and 9, we need to find the multiples of 5 and 9 (multiples of 5 = 5, 10, 15, 20 . . . . 45; multiples of 9 = 9, 18, 27, 36 . . . . 45) and choose the smallest multiple that is exactly divisible by 5 and 9, i.e., 45.

Answer:

(1)

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180° .

consider the inner triangle where

a + b + 58° = 180° ( subtract 58° from both sides )

a + b = 122°

consider the outer triangle where

c + d + 63° = 180° ( subtract 63° from both sides )

c + d = 117°

Then

a + b + c + d = 122° + 117° = 239°

Hannah had run 6 complete laps and is running the 7th lap when she surpasses the athlete Kara.

An athlete (sometimes known as a sportsman or sportswoman) is a person who participates in one or more sports that require physical stamina, speed, or strength.

Professional and amateur athletes both exist. The majority of elite athletes have extremely well-developed bodies because to rigorous physical training, stringent exercise, and a tight food regimen.

Isotonic exercisers had a greater mean left ventricular end-diastolic capacity and are less prone to experience depression. Athletes are far more prone than the general public to go to massage parlors and pay for the services of massotherapists and masseurs due to their demanding physical activity. Athletes whose sport favors endurance over strength typically consume less calories than other athletes.

Calculations:

Total length of the race (L) = 5000 m

Time taken by Kara (tk) = 17.9 min = 1074 s

Kara's speed (vk) = L/tk = 5000/1074 m/s

Time taken by Hannah (th) = 15.3 min = 918 s

Hannah's speed (vh) = L/th = 5000/918 m/s

Let the number of laps Hannah had run when she passes Kara be n

Distance travelled by Hannah in this time = n*400 = 400n meters

Time taken by Hannah to run n laps = 400n/(5000/918)=367200n/5000=73.44n

Distance travelled by Kara in this time = (n-1)*400 = 400n - 400 meters

Time taken by Kara to run (n-1) laps = (400n-400)/(5000*1074)=(429600n-429600)/5000=85.92n-85.92

= 85.92n - 85.92 = 73.44n

= 12.48n = 85.92

The length of AC is 6.228 cm.

Here the angle of the triangle ∡ABC is 40°, AB = BC = 9.

We have to find the length of AC which is opposite to ∡B.

Let AB = BC = x , AC = c

From the cosine formula, we know that

[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - 2ab cos α

Here c is the length of the side opposite to the angle α, and a, b is the side adjacent to the angle α.

So from the cosine formula we have

[tex]c^{2}[/tex] = [tex]x^{2}[/tex] + [tex]x^{2}[/tex] -2[tex]x^{2}[/tex]cos α

[tex]c^{2}[/tex] = 2[tex]x^{2}[/tex] - 2[tex]x^{2}[/tex] cos 40°

   = 2[tex]x^{2}[/tex](1- cos 40°)

   = 2 ×[tex]9^{2}[/tex] ( 1 - 0.76)

    = 2 × 81 × 0.24

c = 2 × 9 × 0.2×√3

  =3.6 × 1.73

  = 6.228cm

Therefore the length of the side AC is 6.228cm.

If two marbles are randomly chosen from the bag contains 22 yellow marbles and 11 teal marbles, then the probability that the both marbles are teal is [tex]\frac{10}{99}[/tex]

Given,

The number of yellow marbles = 22

Number of teal marbles = 11

Total number of marbles = 22+11= 33 marbles

Then two marbles are chosen randomly

We know,

The probability = Number of favorable outcomes/ Total outcomes

Probability that first marble is teal =[tex]\frac{11}{33}[/tex]=[tex]\frac{1}{3}[/tex]

Probability that second marble is teal =[tex]\frac{10}{33}[/tex]

Here we are considering without replacement

Then the probability that both marbles are teal = [tex](\frac{1}{3})(\frac{10}{33})=\frac{10}{99}[/tex]

Hence, if two marbles are randomly chosen from the bag contains 22 yellow marbles and 11 teal marbles, then the probability that the both marbles are teal is [tex]\frac{10}{99}[/tex]

Given that the study was conducted using a sample of 513 bolts produced at a single facility when there is no bias resulting from data gathering procedures, broad inferences may then be drawn.

All bolts manufactured by that factory would be covered by the conclusion?

Due to the fact that bolts made in the same factory will follow the results of an analysis of a sample made up of bolts from the same factory. The finding or conclusion would therefore be applicable to all bolts produced in the same factory because the environment for experimentation and production is the same there while it may differ in other factories.

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. In contrast, a high or low standard deviation indicates that the data points are, respectively, above or below the mean. A standard deviation that is close to zero implies that the data points are close to the mean. the curve at the top is more dispersed and has a greater standard deviation than the curve at the bottom, which is more concentrated around the mean and has a lower standard deviation.

We base the formula described above on the diameter of this photograph of the sun. The diameter of the sun's picture on the card is now measured because we can choose the distance between the cards, and we already know that the sun is nearly 150 million kilometers away from the earth. i.. e.
