Answer:

\huge\boxed{C.\ \dfrac{1-7}{9-5}=\dfrac{1-10}{9-3}}

Step-by-step explanation:

slope=\dfrac{y_2-y_1}{x_2-x_1}

C(9;\ 1)\\E(5;\ 7)\\B(3;\ 10)\\\\slope_{EC}=\dfrac{1-7}{9-5}=slope_{CE}\\\\slope_{BC}=\dfrac{1-10}{9-3}=slope_{CB}

PLEASE HELP FAST!! |x+5|>-1, what is x (answer in x equals to)
Daniel [21]
(x+5)>-1 or -(x+5)>-1

x>-1-5  or  x

x>-6  or  x

This gives us the union of two sets

(-∞,-4) U (-6,+∞)

=(-∞,+∞)

x belongs to all real numbers

What happens to the value of the expression 150-j150−j150, minus, j as jjj decreases?
nikklg [1K]

Answer:

The value of the expression increases as j decreases

Step-by-step explanation:

Let f(j) = 150 - j150 - j150

f(j) = 150 - j300

As j decreases, the value of j300 decreases (i.e the farther j300 is from 150). Due to the wider gap between 150 and j300, the value of f(j) increases.

For example:

When j = 1, f(j) = 150 - (300*1) = -150

When j = 0.5, f(j) = 150 - (300*0.5) = 0

When j = 0. f(j) = 150 - (300*0) = 150

It is obvious from the analogy above that the expression 150-j150−j150 increases as j decreases

Experience raising New Jersey Red chickens revealed the mean weight of the chickens at
Nikolay [14]

Answer:

p-value = 0.1277

Step-by-step explanation:

p-value is the probability value tell us how likely it is to get a result like this if the Null Hypothesis is true.

Firstly we find the mean and standard deviation of the given data set.

⇒ Mean = \frac{4.41 +4.37+ 4.33+ 4.35 +4.30 +4.39 +4.36+ 4.38+ 4.40+ 4.39}{10}

⇒ Mean = 4.368

Standard deviation(\sigma) = \sqrt{\frac{1}{n}\sum_{i=1}^{n}{(x_{i}-\bar{x})^{2}} }

where, \bar{x} is mean of the distribution.

⇒ Standard Deviation = 0.034

Applying t- test:

Let out hypothesis is:

H₀: μ = 4.35

H₁: μ ≠ 4.35

Now,

Here, μ = Population Mean = 4.35

\bar{x}= Sample Mean = 4.368

σ = Standard Deviation = 0.034

n = 10

t=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}} }

Putting all values we get, t = 1.6777 with (10 -1) = 9 degree of freedom.

Then the p-value at 99% level of significance.

⇒ p-value = 0.1277
