Answer

Since an isosceles triangle is a triangle that as two sides that are the same length and one side that isn't. We know that one side(the the side that is'nt the same lenght as the others) is 72cm and a triangle is 180 degrees then you would subtract 72 from 180 which would leave you with 108 then you would divide 108 to find the value of x which is 54.

Answer:

X = 116

Step-by-step explanation:

Total heptagon angle = 900

124 + 120 + 122 + 136 + 144 + 138 = 784

900 - 784 = 116

Hannah is saving money for a car. She earns $160 each week working part time after school and on the weekends at Papa's Pizza. H
Yuliya22 [10]
From the problem we know that Hanna saves one-half of her paycheck each week, so she saves ( \frac{1}{2})(160)= \frac{160}{2} =80. Also, we know that her parents put $50 in her savings account each week, so the total amount she and her parents put in her saving's account is 80+50=130.
Since we know that Hanna currently has <span>$1,280 in her saving's account and each week she and her parents deposit $130 to the account, with </span>n representing the number of weeks, we can model the situation as follows:
f(n)=1280+130n

aleksklad [387]

Answer:

 The conclusion is that the researcher was correct

Step-by-step explanation:

From the question we are told that

     The sample size is  n =  13

    The sample mean is  \= x =  9.63

     The standard deviation is  s =  0.585

      The significance level is  \alpha  =  0.05

The Null Hypothesis is  H_o :  \mu = 0

The Alternative  Hypothesis  is  H_a =  \mu < 10

The test statistic is  mathematically represented as

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

Substituting values

          t =  \frac{9.63  - 10 }{\frac{0.585}{\sqrt{13} } }

         t =  -  2.280

Now the critical value for \alpha is  

     t_{\alpha } = 1.645

This obtained from the critical value table

  So comparing the critical value of alpha and the test value we see that the test value is less than the critical value so the Null Hypothesis is rejected

 The conclusion is that the researcher was correct
