X = 1

6(4x+2) = 3(8x+4)
24x + 12 = 24x + 12
-12 -12
24x = 24x
-24 -24
x = x

n200080 [17]
X + y = 47
x = y + 13

y + 13 + y = 47
2y + 13 = 47
2y = 47 - 13
2y = 34
y = 34/2
y = 17

x = y + 13
x = 17 + 13
x = 30.....longer piece is 30 inches

USPshnik [31]
There are 2000 pounds in a ton - so the rino weighs 3.75 x 2000 = 7500 pounds

a percentage can be converted to a decimal - if you want to know what 3.8% of a number is, move the decimal two spaces to the left 3.8% is 0.038 - 

Multiply 7500 pounds by 0.038 - the answer is 285 pounds.

When testing a hypothesis about a single mean, a sample size of 200 is selected from a normally distributed population. If the p
Evgen [1.6K]

Answer:

Null hypothesis:\mu \leq \mu_o  

Alternative hypothesis:\mu > \mu_o  

If we analyze the size for the sample is > 30 and we know the population deviation so is better apply a z test to compare the actual mean to the reference value, and the statistic is given by:  

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

z-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".  

Step-by-step explanation:

Data given and notation  

\bar X represent the sample mean

\sigma represent the population standard deviation for the sample  

n=200 sample size  

\mu_o 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 mean is equal to \mu_o, the system of hypothesis would be:  

Null hypothesis:\mu \leq \mu_o  

Alternative hypothesis:\mu > \mu_o  

If we analyze the size for the sample is > 30 and we know the population deviation so is better apply a z test to compare the actual mean to the reference value, and the statistic is given by:  

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

z-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".
