Answer:

Step-by-step explanation:

y - y1 = m(x - x1)

ur points are gonna be x1 and y1

y - 3 = 3(x + 1)

so ur y point is gonna be -3

but ur x point is gonna be -1.......because 3(x + 1) is the same as 3(x - (-1)

ur point is (-3,-1)

Write an equation in point-slope form for the line that has a slope of 45 and contains the point (−5,−3).
olga55 [171]

Answer:

y+3=45(x+5)

Step-by-step explanation:

Hi there!

Point-Slope Form:

y-y1=m(x-x1)

Where

y1 stands for the y-coordinate of the point

m stands for the slope of the line

x1 stands for the x-coordinate of the point

In this case, the slope is 45, the y-coordinate of the given point is -3, and the x-coordinate of the point is -5.

Plug in the values and solve:

y-y1=m(x-x1)

y-(-3)=45(x-(-5)

y+3=45(x+5)

Hope it helps!

Enjoy your day!

Please feel free to ask if you have any doubts.

Polymer composite materials have gained popularity because they have high strength to weight ratios and are relatively easy and
Brums [2.3K]

Answer:

t=\frac{51.6-48}{\frac{1.1}{\sqrt{10}}}=10.349      

p_v =P(t_9>10.349)=1.34x10^{-6}  

If we compare the p value and the significance level given for example \alpha=0.05 we see that p_v so we can conclude that we reject the null hypothesis, and the the actual mean is significantly higher than 48 MPa at 5% of significance.

Step-by-step explanation:

1) Data given and notation      

\bar X=51.6 represent the sample mean

s=1.1 represent the standard deviation for the sample      

n=10 sample size      

\mu_o =48 represent the value that we want to test    

\alpha=0.05 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 determine if the mean score is higher than 48, the system of hypothesis would be:      

Null hypothesis:\mu \geq 48      

Alternative hypothesis:\mu > 48      

We don't know the population deviation, so for this case is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:      

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

t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".  

Calculate the statistic      

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

t=\frac{51.6-48}{\frac{1.1}{\sqrt{10}}}=10.349      

Calculate the P-value      

First we find the degrees of freedom:

df=n-1=10-1=9

Since is a one-side upper test the p value would be:      

p_v =P(t_9>10.349)=1.34x10^{-6}  

Conclusion      

If we compare the p value and the significance level given for example \alpha=0.05 we see that p_v so we can conclude that we reject the null hypothesis, and the the actual mean is significantly higher than 48 MPa at 5% of significance.
