2. How many solutions does this system of equations have?

1 answer:

3 0

Solve using the method comparison method
Then you need to cancel equal terms ---> 3x+4=3x-1 <-----
Then you get this ---> 4= -1
And if you know your math... Like me Lol That equation has no solution Because if you graph these points the lines were parallel
Also, I used Photo math a app to help with math
And my solution is correct

Using the image above, what is the measure of Side AC? Round to the nearest hundredth

Evgesh-ka [11]

To solve this problem, we just have to use trigonometric ratios and apply which of the ratios is needed here and proceed to solve. The value of side AC is 2.85 units

<h3>Trigonometric Ratio</h3>

In the given diagram, we have the value of angle and hypothenuse and we are required to find the adjacent side of the triangle.

Data;

Angle = 32.9 degrees
Hypothenuse = 3.4

Let's use cosine rule for this.

$cos\theta = \frac{adjacent}{hypothenuse}$

Proceed to substitute the values into the equation and solve.

$cos 32.9 = \frac{AC}{3.4} \\AC=3.4cos32.9\\AC = 2.85$

From the calculations above, the value of side AC is 2.85 units

I saw its strength
It pushed and shoved
Moving spring into the past I felt its determination.
It talked with conviction,
Demanding control and respect I smelled its aroma.
It permeated the air,
Providing support and desire. I heard its voice.
It encouraged togetherness,
Allowing warmth to comfort us. I tasted its spirit.
It entertained the masses,
Generating newfound relationships. It woke me up,
Insisting I join the world.
It sheltered my fears,
Providing encouragement and hope.

Summer spoke to me.

How does the first–person perspective in the poem reinforce the idea that summer is an actual being?

a
It is omniscient, which means that it knows everything, so summer must be an actual being.
b
It allows the reader to get into summer's mind and experience what it experiences.
c
It is told from the perspective of summer, which proves that it is an actual being.
d
It gives the impression that the speaker personally encountered summer as an actual being.

Yoonie is a personnel manager in a large corporation. Each month she must review 16 of the employees. From past experience, she

Anarel [89]

Answer:

$P(3.25 < \bar X < 4.25)$

And we can use the z score formula given by:

$z = \frac{\bar X -\mu}{\sigma_{\bar X}}$

And using the z score we have:

$P(\frac{3.5-4}{0.3}< Z< \frac{4.25-4}{0.3}) = P(-1.667< Z< 0.833)$

And we can use the normal standard distribution table or excel in order to find the probabilities and we got:

$P(-1.667< Z< 0.833)= P(Z$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the time it takes her to complete one review, and for this case we know the distribution for X is given by:

$X \sim N(4,1.2)$

Where $\mu=4$ and $\sigma=1.2$

And we select a sample size of n =16. Since the dsitribution for X is normal then the distribution for the sample mean $\bar X$ is also normal and given by:
