Answer:
This is what you have to explain:
With 5n, you are multiplying a number and a variable.
With 5 + n, you are adding a number and a variable.
Answer:
B. <u>the distributive property</u>
Step-by-step explanation:
<u>Distributive </u><u>property</u> can be used to expand the expression -2(3/4x+7).
When that property is used, we need to distrubute the monomial to the binomial which is the two terms.

Answer:
B
Step-by-step explanation:
Here, we are to give the reason why we would reject the null hypothesis during the hypothesis testing.
In considering whether to accept the null hypothesis or reject the null hypothesis, we have to take into consideration two things.
The p-value and the alpha value. The p-value refers to the probability which is directly obtainable from the standard score which is referred to as the z-score while the alpha refers to the level of significance.
Now, when the p-value is less than alpha, we simply reject the null hypothesis and accept the alternative hypothesis. In a case however, we have the value of p greater than or equal to the significance level alpha, we simply accept the null hypothesis in this case.
The question asks for a rejection case and this can happen only when the p-value is less than the level of significance alpha
I'm guessing this is a parallelogram or something, so VR=TS and RS=VT
therefore, y=x+11 and x+2=y-3x
y=x+11 , 2=y-4x
y=x+11 , y=4x+2
then use the process of elimination:
y=4x+2 then plug in: y=3+11
- y=x+11 y=14
0=3x-9 I think this is how you'd do it, tbh it's just an educated
3x=9 , x=3 guess. Btw, sorry if it looks weird
The
equation of velocity of sound in air is v = 20 √(273 + t). In this problem, we
need to find the temperature when the velocity is 329 meters/s. You need
to measure the time it takes a sound to travel a
measured distance in order to measure its speed in air.
Given:
Velocity
of sound in air equation = v = 20 √(273 + t)
Velocity
= 329 m/s
To
solve:
V = 20 √(273 + t)
<span>
329 = 20 * sqrt(273 + t)</span>
<span>
16.45 = sqrt(273 + t)</span>
<span>
273 + t = 16.45^2</span>
<span>
t- 16.45^2-273</span>
<span>
t = -2.4 degrees Celsius</span>
<span>So, the
temperature when the velocity is 329 meters per second is -2.4 degrees Celsius.</span>
