Answer:

Sorry don't know full answer but I know this: In mathematics, an irrational number is a real number that cannot be expressed as a ratio of integers, i.e. as a fraction. Therefore, irrational numbers, when written as decimal numbers, do not terminate, nor do they repeat.

The system of equations is graphed on the coordinate plane. y=−x−2y=3x+2 A graph with a blue line passing through coordinates (-

Brilliant_brown [7]

Y=-x-2
y=3x+2
multiply the first equation by 3: 3y=-3x-6
add up this equation with equation 2: 4y=-4, y=-1
-1=3x+2, x=-1
so the solution point is (-1,-1)

The distribution of the number of siblings for students at a large high school is skewed to the right with mean 1.8 siblings and

morpeh [17]

Answer:

E. Approximately normal with standard deviation less than 0.7 sibling

Step-by-step explanation:

To solve this question, we use the Central Limit theorem.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$

In this problem, we have that:

Skewed right distribution, with $\mu = 1.8, \sigma = 0.7$

Sampling distribution of the sample mean for samples of size 100

By the Central Limit Theorem, they will be approximately normal, with mean $\mu = 1.8$ , and standard deviation $s = \frac{0.7}{\sqrt{100}} = 0.07$

So the correct answer is:

E. Approximately normal with standard deviation less than 0.7 sibling

Leona [35]

If we find the amount of food in grams, it is going to be
$1114+500+410=2024$
And if we divide it among 9 people, it'll be
$\frac{2024}{9}= 224.(8)$
The answer is approximately 224 grams.
(There is a mistake in the question. Instead of the kilogram, there has to be gram I guess)

Brandon is a running back for his local high school football team. In the last game, he carried the ball 8 times. In the first 5

marin [14]

Using it's concept, it is found that Brandon's net yardage for the game was of 26.

<h3>How to find the net yardage?</h3>

The total net yardage is the sum of all the yardage they gain, that is, the positive gains are added with a plus signal, while the negative gains are added with a negative signal.

Hence, his net yardage, considering that he gained <u>20 yards on his last 7 carries</u>, is given by:

6 + 20 = 26.
