Over which interval of the domain is the function increasing?
i didnt mean to click B btw

Answers

Answer:

B

Step-by-step explanation:

It appears to be B because this quadratic function faces down (-ax^2) and the vertex or highest point of this function is when x=1. Thus, the interval of the domain that the function increases must be from negative infinity to 1, giving the answer B.

On a number line, what other number is the same distance from -2.8 as -7.2 is?​

Answers

Answer;

1.6

Explanation

What we shall do here is to calculate the distance between the two points on the number line

Mathematically, that would be ;

-2.8 -(-7.2) = -2.8 + 7.2 = 4.4

This means that -7.2 is 4.4 units away from -2.8

So to find other number which is this same distance;

we have -2.8 + 4.4 = 1.6

Pete bought a 16-ounce box of cereal for $3.58. What was the cost per ounce?

Answers

Answer:

Around 0.22 dollars or 22 cents

Step-by-step explanation:

We know that per 16 ounces it costs 3.58. We want the ounces to equal zero. To do that, we divide 16 by 0, but to keep it equal we need to divide 3.58 by 16. So...

16/16 = 1

3.58/16 = 0.22375

This means that every ounce of cereal, it costs 0.22375 dollars, but money can't go in the thousandths place, so we must round it to the hundredths place, which becomes 0.22 dollars, or 22 cents. I hope this helps and I hope it's not wrong but I don't think it is.

Step-by-step explanation:

"Twenty-three hundredths," or 23/100, is a fraction that cannot be reduced. The mixed number version is ...

  24 23/100

_____

Additional comment

You start with a denominator that corresponds to the place value of the least-significant digit. Here, that's hundredths, so the fraction you start with is some number of hundredths. Then you reduce the fraction if possible, by canceling all factors of 2 or 5 that you can.

Had it been 23.24, you would start with 23 24/100 and cancel a factor of 4 from numerator and denominator: 23 6/25.

Suppose a friend tells you she paid a total of $19,875 for a car, and you’d like to know the car’s list price (the price before taxes) so that you can compare prices at various dealers. Find the list price of the car if your friend bought the car in : Lilburn with a percentage of 7%

Answers

Answer:

10.31%

Explanation:

This is the answer

friend bought the car in  Lilburn with a percentage of 7% ie the price list of the car is  $18483.75.

How do I calculate percentage?If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.The proportion therefore refers to a component per hundred.Per 100 is what the word percent means.The letter "%" stands for it.Percentage, which meaning "per 100," designates a portion of a total sum.The use of percentages is widespread and diverse.For instance, many statistics in the media, bank interest rates, retail discounts, and inflation rates are all expressed as percentages.For comprehending the financial aspects of daily life, percentages are crucial.

The friend paid total of $19,875 for a car.

7% of  19,875 = 1391.25.

The list price of the car = 19,875 -  1391.25 = 18483.75

Each of 12 refrigerators of a certain type has been returned to a distributor because of an audible, highpitched, oscillating noise when the refrigerators are running. Suppose that 7 of these refrigerators have a defective compressor and the other 5 have less serious problems. If the refrigerators are examined in random order, let X be the number among the first 6 examined that have a defective compressor. What is the probability that X exceeds its mean valueby more than 1 standard deviation?

Answers

Answer:

0.121

Step-by-step explanation:

From the given information:

Let X be a hypergeometric random variable. i.e X [tex]\sim[/tex] h (x;:6,7,12)

To determine the mean and the standard deviation of X of a hypergeometric random variable; we have:

[tex]\mu_x = E(X)[/tex]

[tex]\mu_x = 6 \times \dfrac{7}{12}[/tex]

[tex]\mu_x =1 \times \dfrac{7}{2}[/tex]

[tex]\mu_x =3.5[/tex]

The standard deviation is :

[tex]\sigma _x = \sqrt{(\dfrac{12-6}{12-1}) \times 6 \times (\dfrac{7}{12})\times (1-\dfrac{7}{12})}[/tex]

[tex]\sigma _x = \sqrt{(\dfrac{6}{11}) \times 6 \times (\dfrac{7}{12})\times (\dfrac{5}{12})}[/tex]

[tex]\sigma _x = \sqrt{\dfrac{35}{44}}[/tex]

[tex]\sigma _x = 0.892[/tex]

However, the inequality for the event showcasing how X exceeds its mean value by more than 1 standard deviation is :

[tex]X \geq \mu_x +\sigma_x[/tex]

[tex]X \geq 3.5 +0.892[/tex]

[tex]X \geq 4.392[/tex]

[tex]X \geq 5[/tex]

[tex]P(X \geq \mu_x + \sigma_x ) = P(X \geq 5)[/tex]

[tex]P(X \geq \mu_x + \sigma_x ) = 0.121[/tex]

Okay so if your current scores are 93, 97, 89 and 81, You would have to score at least a 90. Even if you scored a 100%, the highest you would be able to make is a 92 average.

Step-by-step explanation:

Here's the thing about average, all you do is take all of the numbers, add them up, then divide them by the number of numbers there are.

For example, 93 + 97 + 89 + 81 = 360. There are 4 numbers so you would take 360 and divide it by 4 which gets you 90. 90 is your average.

To figure out the highest score you are able to get, take the highest score you can possibly score (100) and add it to the mix. 93 + 97 + 89 + 81 + 100 = 460. Now, there are 5 numbers. So you take 460 and divide it by 5 which will get you 92.
