The linear model would be a reasonable way to predict the temperature as temperature determines the number of ice cream that would be sold.

Temperature is a unit of hotness and coldness that can be described in terms of any number of arbitrary scales. It also represents the direction wherein heat energy will naturally flow, from either a hotter (i.e., higher temperature) body to a colder body.

Temperature is not the same as the energy of such a thermodynamic system; for instance, an iceberg has a significantly larger total heat energy than a match, despite the fact that a match is burning at a significantly higher temperature. The linear model would be a reasonable way to predict the temperature as temperature determines the number of ice cream that would be sold.

Therefore, the linear model would be a reasonable way to predict the temperature as temperature determines the number of ice cream that would be sold.

The point after 30, 000 km will they first have to change the oil, rotate the tires and replace the wiper blades all at once.

Arithmetic Progression (AP) is a numerical series in which the difference between any two consecutive numbers is a constant value. Arithmetic Sequence is another name for it.

The First term is an "oil change" with a step d = 3000 km;

and, the second term is tire rotation = 10, 000 Km

and, the third term is replacement of wiper blades = 15, 000 Km

Now, we know from the formula of Arithmetic Progression is

= + d(n-1)

So, 15,000 = 10,000 + 10,000 (n-1)

15, 000 = 10,000 + 10, 000n- 10,000

150000 = 10000n

n = 1.5

This means that at the point 15 000 km and all three progressions will not intersect.

Now, We take the second term of the progression as  = 30,000 km

So, 30,000 = 10,000 + 10,000 (n-1)

20,000 = 10,000n - 10,000

30, 000 = 10,000n

n= 3

Similarly, check this intersection point for the first progression with a step of d = 3 000 km we get n =9.

Answer:

Step-by-step explanation:

A standard deck of cards has 52 cards, including 4 queens. If you are certain to get a queen when selecting 49 cards from a shuffled deck, it means that one of those 49 cards must be a queen, and the remaining 48 cards can be any of the remaining 48 cards in the deck.

So, the probability of selecting a queen from a shuffled deck of cards is:

probability = number of favorable outcomes / total number of possible outcomes

Since we are certain to get a queen, the number of favorable outcomes is 4 (the number of queens in the deck), and the total number of possible outcomes is 49 (the number of cards selected from the deck).

Therefore, the probability of selecting a queen is:

probability = 4/49

This fraction cannot be simplified any further. Since the probability value is between 0 and 1 inclusive, we can express the indicated degree of likelihood as a probability value of approximately 0.0816.

Answer:

Let's assume that the length of the athletics track is "L" units, and let "x" be the speed (in units per minute) at which you run the first lap.

Since you're running two laps, the total distance covered is 2L. The time it takes to complete the first lap is L/x, since time = distance ÷ speed. For the second lap, you want your average speed to be twice the speed of the first lap, so your total time for the second lap must be half the time of the first lap:

Total time for second lap = 0.5 * (L/x) = L/2x

The total time for the two laps is the sum of the time for each lap:

Total time = L/x + L/2x = (2L + L)/(2x) = 3L/(2x)

The average speed for the two laps is the total distance (2L) divided by the total time (3L/2x):

Average speed = (2L) / (3L/2x) = 4x/3

Since you want your average speed for the second lap to be twice the speed of the first lap, you can set up the following equation:

2x = (4x/3) - x

Solving for x, we get:

2x = 4x/3 - x

5x/3 = 0

x = 0

This means that you would have to run the first lap at a speed of 0 units per minute, which is impossible. Therefore, it's not possible to run two laps of an athletics track such that the average speed of the second lap is twice the speed of the first lap.

The factoring of the polynomial expression is presented as follows;

Part A; The greatest common factor is; 5

Part B; 15·x² + 25·x - 10 = 5·(3·x - 1)·(x + 2)

Part C; 5 × (3·x - 1) × (x + 2) = 15·x² + 25·x - 10

A polynomial is an expression containing algebraic terms that consists of variables and coefficients, joined together by operators.

The expression is 15·x² + 25·x - 10

Part A; The greatest common factor of the polynomial is the value that divides each of the terms of the polynomial, therefore;

The greatest common factor of 15·x² + 25·x - 10 is obtained as follows;

The largest number that divides each term of he polynomial expression is 5

15·x² + 25·x - 10 = 5·(3·x² + 5·x - 2)

Part B; The expression, 15·x² + 25·x - 10, can be factored as follows;

15·x² + 25·x - 10 = 5·(3·x² + 5·x - 2)

3·x² + 5·x - 2 = 3·x² + 6·x - x - 2

3·x² + 6·x - x - 2 = 3·x·(x + 2) - 1·(x + 2) = (3·x - 1)·(x + 2)

3·x² + 5·x - 2  = (3·x - 1)·(x + 2)

15·x² + 25·x - 10 = 5·(3·x² + 5·x - 2) = 5·(3·x - 1)·(x + 2)

Factoring the expression completely, we get;

15·x² + 25·x - 10 = 5·(3·x - 1)·(x + 2)

Part C: The factoring of the expression, 15·x² + 25·x - 10, can be checked as follows;

The factored expression is; 5·(3·x - 1)·(x + 2)

5 × (3·x - 1) × (x + 2) = 5 × (3·x² + 6·x - x - 2) = 5 × (3·x² + 5·x - 2)

5 × (3·x² + 5·x - 2) = 15·x² + 25·x - 10, which is the original expression

Move decimal and round up.

Answer:

Step-by-step explanation:

The statement "65% of 150 students" could represent the estimate that 100 students attended the school's play.

To see this, we can calculate 65% of 150:

0.65 x 150 = 97.5

Since 97.5 is close to 100, it is possible that the estimate was based on 65% of 150 students.

The other statements do not come close to 100, so they are not likely to represent the estimate that 100 students attended the school's play.

The first term in this sequence is 7 and the common ratio is -3, so the formula for the 7th term, a7, can be written as a7 = 7(-3)6.7 multiplied by -18 is equal to -126, so the 7th term in this geometric sequence is -126.

Geometric sequences are used to represent growth and decay. The common ratio determines whether the sequence is increasing (if r > 1) or decreasing (if 0 < r < 1). When the common ratio is a whole number, such as 2 or 3, the terms in the sequence are whole numbers as well.

Geometric sequences are sequences where each term is found by multiplying the previous term by a fixed number, called the common ratio. In this case, the first term is 7 and the common ratio is -3, so each term is found by multiplying the previous term by -3. This means that the second term is 7(-3) = -21, the third term is -21(-3) = 63, the fourth term is -63(-3) = -189, and so on. By using the formula a7 = ar6 and substituting in the first term and common ratio, the 7th term can be calculated as -126.

The 7th term of a geometric sequence is calculated by using the formula a7 = ar6, where a is the first term and r is the common ratio. The first term in this sequence is 7 and the common ratio is -3, so the formula for the 7th term, a7, can be written as a7 = 7(-3)6. To calculate this, the exponent 6 must be multiplied by -3, giving -18. 7 multiplied by -18 is equal to -126, so the 7th term in this geometric sequence is -126.

the answer is 42 will be 42 because i answer that before

Answer:

Step-by-step explanation:

The simple interest can be calculated using the formula:

I = P * r * t

where:

P = principal amount = $575

r = annual interest rate = 6.5% = 0.065

t = time period = 10 years

I = 575 * 0.065 * 10

I = $373.75

The new balance can be found by adding the interest to the principal:

New balance = Principal + Interest

New balance = $575 + $373.75

New balance = $948.75

Rounded to the nearest cent, the new balance is $948.75.

Answer:

Step-by-step explanation:

To solve this problem, we need to standardize the IQ score using the formula:

z = (x - μ) / σ

where x is the IQ score, μ is the mean IQ score, and σ is the standard deviation of IQ scores.

So, for x = 98, we have:

z = (98 - 100) / 15 = -0.1333

Using a standard normal distribution table or calculator, we can find that the probability of a standard normal variable being less than -0.1333 is approximately 0.4483.

Therefore, the probability of a random person on the street having an IQ score of less than 98 is 0.4483 (or 44.83% rounded to four decimal places).
