Given the equation p = s Subscript 1 Baseline t minus 2 Subscript 2 Baseline t, which equation is solved for t?

Mathematics

Romashka [77]4 years ago

Answer:

t=\dfrac{p}{(s_1-s_2)}

Step-by-step explanation:

It is given that, p = s Subscript 1 Baseline t minus 2 Subscript 2 Baseline t. It can also written as :

p=s_1t-s_2t

We need to solve the above equation for t.

Taking t common on RHS of the equation :

p=(s_1-s_2)t

Now dividing both sides by (s_1-s_2), so,

\dfrac{p}{(s_1-s_2)}=\dfrac{(s_1-s_2)}{(s_1-s_2)}t\\\\t=\dfrac{p}{(s_1-s_2)}

So, the equation for t is : t=\dfrac{p}{(s_1-s_2)}

The shear strength of each of ten test spot welds is determined, yielding the following data (psi).
Mumz [18]

Answer:

a) Mean = 382.3 psi

Standard deviation = 20.8 psi

b) 392.7 psi

c) P(X<400)=0.8026

Step-by-step explanation:

a) The population mean can be estimated as equal to the mean of the sample, and the population standard deviation can be estimated from the sample standard deviation:

M=\frac{1}{n}\sum x_i=\frac{1}{10}(389+405+409+367+358+415+376+375+367+362)\\\\M=\frac{1}{10}(3823)=382.3\\\\\mu\approx M=382.3

s=\sqrt{\frac{1}{n-1}\sum (x_i-M)^2}=\sqrt{\frac{1}{10-1}(389-382.3)^2+...+(362-383.2)^2}\\\\\\s=\sqrt{\frac{1}{9}(3906.1)}=\sqrt{434}=20.8\\\\\\\sigma\approx s=20.8

b) We start by searching for the z-value for the 95th percentile. This value is

z=1.645:

P(z

Then, the strength value below which 95% of all welds will have their strengths is:

X=\mu+z\cdot \sigma/\sqrt{n}=382.3+1.645*20.8/\sqrt{10}\\\\X=382.3+32.9/3.2=382.3+10.4\\\\X=392.7

c) We calculate the probability of X being equal or less than 400 as:

z=(X-\mu)/\sigma=(400-382.3)/20.8=17.7/20.8=0.851\\\\\\P(X\leq400)=P(z

Confused on one-to-one functions. Just need help 11-14 plz(: thank u
8_murik_8 [283]

11. YES. Because each x-value is only used once (no duplicate x-coordinates)

12. range is the y-values.  the lowest it goes is -2 (with an open dot), then it goes to +2 (with an open dot).  then there is a separate line where y = 4.

Answer: (-2, 2) U [4, 4]

13. f(-1): when x = -1, y = ???  <em>(do not count the open dot!)</em>

Answer: 1

14. f(3): when x = 3, y = ???  <em>(do not count the open dot!)</em>

Answer: 4
