A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. He started at 90 kilograms and gained weight at a constant rate of 8 lbs. a week.

a. Write a function to represent this situation. Use x and y as your variables.

b. What would his weight be after 8 weeks?

Answer: C Or the third answer

Step-by-step explanation:

You square root it and get x+b/2a=±(√b^2-4ac)/√4a^2 which is the third answer or c

Answer:

Third option

Step-by-step explanation:

(x + b/2a)² = (-4ac + b²)/4a²

Square root both sides

x + b/2a = +/- sqrt(b² - 4ac)/sqrt(4a²)

Answer:

x= -6         x=2

Step-by-step explanation:

x^2 + 4x - 12 = 0

Factor,  what 2 terms multiply to -12 and add to 4

6* -2 = -12

6+-2 = 4

( x+6) (x-2) =0

Using the zero product property

x+6 =0    x-2=0

x= -6         x=2

Answer:

option C will be the correct answer

x= 2 or x = -6

Step-by-step explanation:

[tex]x {}^{2} + 4x - 12 = 0? \\ {x}^{2} + 6x - 2x - 12 = 0 \\ x(x + 6) - 2(x + 6) = 0 \\ (x - 2)(x + 6) = 0 \\ x - 2 = 0 \: \: \: \: or \: \: \: \: x + 6 = 0 \\ x = 2 \: \: \: \: or \: \: \: \: x = - 6[/tex]

Final answer:

The correct statement is B, which describes the weight loss range for the middle 50 percent of the members, indicating an interquartile range scenario.

Explanation:

The question you've asked seems to pertain to data interpretation and understanding statistical statements regarding weight loss in a specific group of members. This seems to be a statistical analysis question which falls under the subject of Mathematics. Specifically, this question is likely related to the topics of median, quartiles, and potentially, data distribution covered in high school level mathematics.

Based on the provided statements, the correct assertion appears to be B. The middle 50 percent of the members lost from two to 8.5 lbs. This statement indicates that the middle 50 percent is referring to the interquartile range in statistical terminology, which is a measure of statistical dispersion being the difference between the 75th and 25th percentiles. Choices A and C don't provide enough information to confirm their accuracy without additional context, and choice D cannot be correct without both A and C being correct.

Answer:

5) 27/70

6) 90

Step-by-step explanation:

5) The first step in this problem is to figure out the amount of total spins. To do so, add up all of the numbers in the column "Frequency".

18 + 15 + 27 + 10 = 70.

Now, look at the amount of times the spinner landed on green. This is 27 times. So, the ratio of green spins to total spins is 27:70, or 27 out of 70 spins. Converting this to a fraction, we get the final answer, 27/70.

6) To solve this problem, we have to first do the same steps as the previous problem, but with the color red. There are 70 total spins, and 18 red spins. Therefore, the ratio is 18:70. However, this problem wants the total number of spins to be 350. In other words, 70 needs to become 350. To do this, multiply each side of the ratio by 5. The ratio becomes 90:350. Using this ratio, we can determine that a solid prediction is 90 red spins out of 350 total spins.

Answer:

5) 27/70

6) 90

Step-by-step explanation:

5)

What is the probability of spinning green?

Here are all of the values in the table:

Red = 18

Yellow = 15

Green = 27

Purple = 10

Add them together

= 70

Write green / total as a fraction

27/70

6)

Red = 18

Yellow = 15

Green = 27

Purple = 10

Write red / total (70) as a fraction

18/70

Multiply both the numerator and denominator by 5 to get a denominator of 350

18 * 5 / 70 * 5

90/350

Remove the denominator to find how many times he chose red out of 350 trials

90

Answer:

- 515

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 15 and d = - 35 - (- 15) = - 35 + 15 = - 20, thus

[tex]a_{26}[/tex] = - 15 + (25 × - 20) = - 15 - 500 = - 515

Answer:

-515

Step-by-step explanation:

In this example the first value is −15 and every value afterwards is 20 less.After substituting these values to above formula, we obtain: All we have to do is add 25 twenties or 25 x 20 = 500 and -15 - 500 = -515

When you subtract 9 from the variable "b," you get the expression:

b - 9

When you subtract 9 from the variable "b," you are performing a basic arithmetic operation in algebra. This subtraction results in a new value, which is b decreased by 9 units. In mathematical terms, it can be represented as:

b - 9

This expression represents the concept of taking a quantity, "b," and reducing it by 9. The result will depend on the specific value of "b." For example, if b = 15, then b - 9 would equal 6. If b = 20, then b - 9 would equal 11. In essence, subtracting 9 from "b" simply means subtracting 9 from the value represented by "b," whatever that value may be.

Answer:

(27/36) = (3/4) = 0.75

Step-by-step explanation:

The complete question is attached to this solution.

P(9 or fewer boxes) = P(x ≤ 9)

Since Vera carried out the simulation/experiment, this probability will be read from the results of her simulation (the dotplot).

Note that the dots on the numbers of the dotplot represent the number of boxes it took Vera to get all the prizes.

So, the probability of getting all the prizes in 9 or fewer boxes will be just counting the number of times in the simulation where she got the 4 prizes in 9 boxes or fewer.

This starts from the least number on the dotplot, 4 all the way to 9.

Total number of simulations = 36

P(x ≤ 9) = P(x=4) + P(x=5) + P(x=6) + P(x=7) + P(x=8) + P(x=9)

= (4/36) + (6/36) + (3/36) + (4/36) + (4/36) + (6/36) = (27/36)

This question is about the Coupon Collector's problem in probability theory. The expected number of cereal boxes one would need to buy to collect all 444 prizes can be calculated using the formula for the expected value of the coupon collector's problem: E[X] = n*(1 + 1/2 + 1/3 + ... + 1/n).

This problem is essentially a mathematical statistics problem, more specifically, it involves the concept of probability and expected value. In this case, the company is inserting a prize into each box of cereal. There are 444 unique prizes, and the probability of getting any specific prize is 1 out of 444. Therefore, the number of boxes one would need to buy to collect all prizes follows what is known as the Coupon Collector's problem in probability theory.

The expected number of boxes one would need to buy can be calculated using the formula for the expected value of the coupon collector's problem: E[X] = n*(1 + 1/2 + 1/3 + ... + 1/n), where n is the number of unique prizes.

Plugging n = 444 into the formula gives us: E[X] = 444*(1 + 1/2 + 1/3 + ... + 1/444). For a large number of trials, this value will closely approximate the average number of boxes one would need to buy to collect all 444 prizes.

Step-by-step explanation:

The ratio of a right angle to the total degrees in a circle is 90:360, which simplifies to a ratio of 1:4.

The ratio of a right angle to the total degrees in a circle can be found by comparing the degree measures of each. A right angle is 90 degrees, and a full circle is 360 degrees.

Therefore, the ratio of a right angle to the total degrees in a circle is 90:360.

When simplifying this ratio, we divide both terms by 90, the degree measure of the right angle, which gives us 1:4.

Hence, the ratio is simplified to 1:4.

One cone is oblique.

The cones have different slant heights.

The lengths of all corresponding edges are not equal.

Congruent cones must have congruent corresponding measures, including slant height.

Hope this helps!

The two cones are congruent because they have the same radius, height, and volume - all factors that determine a cone's size and shape.

Yes, the two cones are congruent. In mathematics, two shapes are considered congruent when they have the exact same size and shape. When it comes to cones, this means that they possess the same radius and height. Since the question states that both the radius and height of the two cones are the same, we can deduce that the cones are congruent. The volume of a cone is determined by its radius and height (V=1/3πr²h) and since this is also the same for the two cones, it backs up the claim of congruency.

Answer:

D

Step-by-step explanation:

like it said, he used 5 instead of the actual height which is 4

Answer:

D

Step-by-step explanation:

The area of a parallelogram is denoted by: [tex]A=bh[/tex] , where b is the base and h is the height that is perpendicular to the base. Depending on what kind of parallelogram it is (square, rectangle, rhombus, regular parallelogram), that height could be the side length, but usually it is not; it is only the side length in special cases, like a square.

Here, we are given that the base is 11 and that the height is 4. Since the problem gives us two different values for the height versus the side length, we know that for this parallelogram, the height is not the same as the side length. Thus, we must use 4 for the height and 11 for the base in the area formula.

Therefore, the only answer that correctly points out this mistake is D.

Final answer:

To find the number that when added to 1/2 equals 7/8, convert 1/2 to 4/8 so both fractions have a common denominator. Subtract 4/8 from 7/8, resulting in 3/8. Thus, 1/2 plus 3/8 equals 7/8.

Explanation:

The student is asking us to find the number that, when added to 1/2, equals 7/8. To solve this, we need to find a common denominator, which is 8 in this case. For 1/2, we multiply the numerator and denominator by 4 to convert it to 4/8. Now we have a common denominator, so we can find the missing number.

7/8 - 4/8 = 3/8

Therefore, 1/2 plus 3/8 equals 7/8. This calculation is based on the intuition that a number is needed to bridge the gap between 4/8 and 7/8.
