Answer:

The temperature now is - 11.f

Step-by-step explanation:

If it was - 4.f and now it is 7.f colder, so then all we have to do is subtract 7.f from -4.f and get...

-4.f - 7f. = - 11.f

Therefore the current temperature is - 11.f

Use the distributive property to write an expression that is equivalent to: 3(x + 5)
lana [24]

Answer:

3x=15

Step-by-step explanation:

Here's what I found on google about the distributive property-

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Now for the math-

3(x+5)

distribute the numbers-  3(x)+3(5)

solve-  3*5=15

3x+15

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

How do I do this ??
Nostrana [21]

Answer:

If I'm not mistaking, they want you to find the number in the middle that's between X and Z.

That number would be 3.

Hope this helps a bit! :)
