The length of the midsegment of a triangle is always half the length of the side it is parallel to true or false
Vladimir [108]
True. The midsegment of a triangle is halfway up the triangle, and since the top half and the full triangle are similar triangles, its dimensions are proportional.

This means half the height will give half the base (midsegment). So the midsegment is always half the length of the side it's parallel to.

Khloe and Emma work at a furniture store. Khloe is paid $245 per week plus 9.5% of her total sales in dollars, xx, which can be
ale4655 [162]

Answer: Their weekly pay would be the same if xx equals $1,600

Step-by-step explanation: The first and most important step is to identify what the question requires, and that is, what is the value of the unknown in the equation of their weekly incomes that would make their pay to be the same? Their weekly pay as per individual is given as follows;

Khloe = 245 + 0.095x ———(1)

Emma = 285 + 0.07x ———(2)

Simply put, we need to find the value of x when equation (1) equals equation (2)

245 + 0.095x = 285 + 0.07x

Collect like terms and we now have

0.095x - 0.07x = 285 - 245

0.025x = 40

Divide both sides of the equation by 0.025

x = 1600

Therefore their weekly pay would be at the same level, if x equals $1600

Dullco Manufacturing claims that its alkaline batteries last at least 40 hours on average in a certain type of portable CD playe
algol13

Answer:

The value is  p- value  = 0.041815

Step-by-step explanation:

From the question we are told that

  The  population mean is \mu  =  40 \ hours

  The  sample size is  n  =  18

    The  sample mean is  \= x =  37.8 \ hours

   The standard deviation is  \sigma  = 5.4\ hours

The null hypothesis is  H_o  :  \mu =  \ge 40

The alternative hypothesis is  H_a  :  \mu < 40 \ hour s

Generally the test statistic is mathematically evaluated as

       t=  \frac{\= x - \mu}{ \frac{\sigma}{ \sqrt{n} } }

      t=  \frac{37.8 - 40}{ \frac{5.4}{ \sqrt{18 } }

      t=  -1.73

From the z - table the p-value is obtained and the value is  

      p- value  =  P(Z <  -1.73)

        p- value  = 0.041815
