What is the value of X?<br><br> Please help! I suck at math but need to pass

Rama09 [41]

Answer:

Step-by-step explanation:

Because To get a single x you would have to divide 5x by 5. Whatever you do to one side you have to do to the other so you would do 5 x/5 and get 10/5 and then x=10/5 and 10/5 equals 2 so...x=2 , Hope this helped!

A car traveled 300 meters in 30 seconds. A truck traveled 600 meters in 60 seconds. Which car was faster ?

rewona [7]

Multiply the car by 2: 300 meters x 2 = 600 meters

30 seconds x 2 = 60 seconds.

The car also traveled 600 meters in 60 seconds, so the speed of the vehicles are the same.

No vehicle was faster.

The director of a state agency believes that the average starting salary for clerical employees in the state is less than $30,00

Answer:

The test statistics is $z = -1$

Step-by-step explanation:

From the question we are told that

The sample size is n = 100

The null hypothesis is $H_o : \mu = \$30000$

The alternative hypothesis is $H_a : \mu < \$ 30000$

The sample mean is $\= x = \$29,750$

The standard deviation is $\sigma = \$2,500$

The level of significance is $\alpha =0.05$

Generally the test statistics is mathematically represented as

$z = \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }$

=> $z = \frac{29750 - 30000 }{ \frac{ 2500}{ \sqrt{100} } }$

=> $z = -1$
