Answer:

x=5

Step-by-step explanation:

Hi there! So when it comes to these two angles, you have to set them equal to each other. From there, you have to isolate the x values, so I subtracted x from the 3x and added 15 to the -5. If you plug in the 5 for the x values, both give the value of 0, so it all checks out. I hope this helped! Please mark this as brainliest if I managed to get this correct. <3

The volume of a cone with a height of 4 cm is 12π cubic cm. What is the radius of the base?

blondinia [14]

Answer:

r = 6cm

Step-by-step explanation:

Solve for r:

$v = \frac{1}{3} \pi {r}^{2}$

$12\pi = \frac{1}{3} \pi {r}^{2} \\ 12\pi = \frac{\pi {r}^{2} }{3} \\ 3 \times 12\pi = \pi {r}^{2} \\ 36\pi = \pi {r}^{2} \\ \frac{36\pi}{\pi} = \frac{\pi {r}^{2} }{\pi} \\ \sqrt{ {r}^{2} } = \sqrt{36} \\ r = 6$

If y varies inversely as x and y=32 when x=3, find x when y=15

deff fn [24]

Y=kx, k is not equal to 0
when y=32,x=3, 32=3k
k=32/3
so y=32/3*x
when y=15, 15=32/3*x
x=45/32

A forester studying diameter growth of red pine believes that the mean diameter growth will be different from the known mean gro

-Dominant- [34]

Answer:

$t=\frac{1.6-1.35}{\frac{0.46}{\sqrt{32}}}=3.07$

The degrees of freedom are given by:

$df =n-1= 32-1=31$

Since is a two-sided test the p value would be:

$p_v =2*P(t_{31}>3.07)=0.0044$

Since the p value is a very low value we have enough evidence to conclude that true mean is significantly different from 1.35 in/year at any significance level commonly used for example ( $\alpha=0.01,0.05, 0.1, 0.15$ ).

Step-by-step explanation:

Data given and notation

$\bar X=1.6$ represent the sample mean

$s=0.46$ represent the sample deviation

$n=32$ sample size

$\mu_o =1.35$ represent the value that we want to test

$\alpha$ represent the significance level for the hypothesis test.

t would represent the statistic (variable of interest)

$p_v$ represent the p value for the test (variable of interest)

State the null and alternative hypotheses.

We need to conduct a hypothesis in order to check if the true mean is different from 1.35 in/year, the system of hypothesis would be:

Null hypothesis: $\mu =1.35$

Alternative hypothesis: $\mu \neq 1.35$

The statistic is given by:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$ (1)

Calculate the statistic

We can replace in formula (1) the info given like this:

$t=\frac{1.6-1.35}{\frac{0.46}{\sqrt{32}}}=3.07$

P-value

The degrees of freedom are given by:

$df =n-1= 32-1=31$

Since is a two-sided test the p value would be:

$p_v =2*P(t_{31}>3.07)=0.0044$
