Advocard [28]3 years ago

Answer:

5. The answer is 2

6. Her error is that she was supposed to subtract 16 minus 12 instead of 12 minus 2.

Step-by-step explanation:

For number 5 all I did was solve.

12 + (25 - 5^2) - 2 =

12 + 0 - 2 =

12 - 2 = 10

10 ÷ 5 = 2

So, for number 5 the answer is 2.

For number 6, you should know that when there are only plus and minus signs you solve from left to right.

She instead put parentheses where there shouldn't of been, and because of that she is wrong.

Hope this helps! :)

Find the slope between 2 points. <br> (16, 12) (40,18)
WITCHER [35]

Answer:

\frac{1}{4}

Step-by-step explanation:

In this question, we have to find the slope with the given coordinates.

To find our slope, we would use the slope formula: m = \frac{y2-y1}{x2-x1}

Plug in your coordinates and solve:

m = \frac{18-12}{40-16}\\\\m=\frac{6}{24}

Simplify the fraction:

m=\frac{1}{4}

The slope would be \frac{1}{4}

The time needed for all college students to complete a certain paper-and-pencil maze follows a normal distribution with a popula
oee [108]

Answer:

The correct option is a

Step-by-step explanation:

From the question we are told that

   The population mean is  \mu = 30\ seconds

    The standard deviation is  \sigma = 3 \ seconds

     The sample size is  n  = 9

    The null hypothesis is H_o: \mu  = 30

     The alternative hypothesis is  H_a  :  \mu \ne 30

    The level of significance is  \alpha = 0.01

    The sample mean is  \= x = 31.2

Generally the test statistics is mathematically represented as

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

=>   z = \frac{ 31.2 - 30}{ \frac{3}{\sqrt{9} } }

=>   z = 1.2

From the z table  the area under the normal curve to the right corresponding to  1.2  is    

         P(Z >  1.2) =  0.11507

Generally the p-value is mathematically represented as

         p-value = 2 * P(Z >  1.2)

=>       p-value = 2 *0.11507

=>       p-value = 0.230

From the value obtained w can see that

         p-value  > \alpha hence

The decision rule is  

Fail to reject the null hypothesis

The conclusion is there is not enough evidence to support the claim
