Answer:

3.02L

Step-by-step explanation:

We would be applying Boyle Law to this question.

Boyle's Law states that volume of a gas at a constant temperature is inversely proportional to the applied pressure when the temperature and mass remains constant.

Mathematically Boyle's law =

P₁V₁=P₂V₂

From the question ,

P₁ = 153kpa

V₁ = 4.00L

P₂ = 203kpa

V₂ = unknown

Therefore,

153kpa × 4.00L = 203kpa × V₂

612 = 203V₂

V₂= 612 ÷ 203

V₂ = 3.02L

17+m=8 one step equations
lilavasa [31]

Answer:

m= -9

Step-by-step explanation:

17 + m = 8

subtract 17 from both sides

(17-17) + m = 8-17 = -9

m= -9   check answer by replacing m with -9

17 + (-9)= 8

The formula for the area A of a triangle is A=(1/2)bh, where b is the length of the base and h is the height. Rearrange the form
zalisa [80]

Answer:

b=\dfrac{2A}{h}

Step-by-step explanation:

The formula for the area of a triangle is given by :

A=\dfrac{1}{2}bh ...(1)

Where b is the length of the base and h is the height.

We need to find the value of b from the above formula.

Cross multiplying equation (1) we get :

2A=bh

Now dividing both sides by h. So,

\dfrac{2A}{h}=\dfrac{bh}{h}\\\\b=\dfrac{2A}{h}

So, the correct option is (D) i.e. \dfrac{2A}{h}.

Someone please help me with math linear equations 3x + 2y = 12
vodka [1.7K]
3x + 2y = 12
subtract 3x from both sides
2y = -3x + 12
divide all terms by 2 so that you can have only the y on the left side
y = -3/2x + 6
And that is your answer!

Hope this helped!! :)

Test the claim that the mean GPA of night students is larger than 3.1 at the .10 significance level. The null and alternative hy
Alborosie

Answer:

H 0 : μ = 3.1    H 1 : μ > 3.1

And this test is defined a a right tailed test since the symbol for the alternative hypothesis H1 is >.

t = \frac{3.13-3.1}{\frac{0.03}{\sqrt{75}}}= 8.66

df = n-1=75-1 =74

The p value is:

p_v = P(t_{74} >8.66) =3.65x10^{-13}

The significance level is: 0.1 or 10%

And since the p value is very low compared to the significance level we have enough evidence to:

Reject the null hypothesis

Step-by-step explanation:

For this case we want to test the claim that mean GPA of night students is larger than 3.1 at the .10 significance level. The claim needs to be on the alternative hypothesis so then we have the following system of hypothesis:

H 0 : μ = 3.1    H 1 : μ > 3.1

And this test is defined a a right tailed test since the symbol for the alternative hypothesis H1 is >.

We have the following info given:

\bar X = 3.13 , s =0.03 , n =75

The statistic to check the hypothesis is given by:

t = \frac{\bar X -\mu}{\frac{s}{\sqrt{n}}}

Replacing the info given we got:

t = \frac{3.13-3.1}{\frac{0.03}{\sqrt{75}}}= 8.66

The degrees of freedom are given by:

df = n-1=75-1 =74

The p value since is a right tailed ted is given by:

p_v = P(t_{74} >8.66) =3.65x10^{-13}

The significance level is 0.1 or 10%

And since the p value is very low compared to the significance level we have enough evidence to:

Reject the null hypothesis
