4. A

5. B

6. C

7. A

8. first do everything to get get x alone on its own side by subtracting or adding, for step two you take anything that is times x and divide it by the other side to get the answer for x. You should plug x into the original equation to check your answer.

Step-by-step explanation:

3. add 23 to both sides x=4. B

4. multiply the bottom number by the 5 which gives you 25 A

5. subtract 6 from both sides and divide by 3 which gives you 5

6. add 9 to both sides and divide by 7 so x = 6

7. subtract seven and you get x= 21

8. first do everything to get get x alone on its own side by subtracting or adding, for step two you take anything that is times x and divide it by the other side to get the answer for x. You should plug x into the original equation to check your answer.

Question
AlekseyPX

Answer:

The population mean is 5 volts

Step-by-step explanation:

Output voltage is assumed to be normally distributed, with standard deviation 0.25 Volts

s=0.25

n = 8

H_0:\mu = 5\\H_a:\mu \neq 5

Sample mean = \bar{x}=4.85

Since n < 30 and population standard deviation is unknown

So, we will use t test

Formula : t = \frac{x-\mu}{\frac{s}{\sqrt{n}}}

t = \frac{4.85-5}{\frac{0.25}{\sqrt{8}}}

t=-1.69

Refer the t table for p value

Degree of freedom = n-1 = 8-1 = 7

So,t_{(df,\alpha)}=t_{7,0.05}=2.365

P value >α

So, We are failed to reject null hypothesis

Hence The population mean is 5 volts
