A "regular quadrilateral" is a square, so the length and width are both 4 cm. The surface area of a rectangular prism is given by
  S = 2(LW +H(L +W))
  S = 2((4 cm)*(4 cm) +(6 cm)*(4 cm +4 cm))
  S = 2(16 cm² +48 cm²)
  S = 2*64 cm² = 128 cm²
The surface area of the prism is 128 cm².

Answer:
There is no sufficient evidence to reject the company's claim at the significance level of 0.05
Step-by-step explanation:
Let  be the true mean weight per apple the company ship.  We want to test the next hypothesis
 be the true mean weight per apple the company ship.  We want to test the next hypothesis
 vs
 vs  (two-tailed test).
 (two-tailed test).
Because we have a large sample of size n = 49 apples randomly selected from a shipment, the test statistic is given by
 which is normally distributed. The observed value is
 which is normally distributed. The observed value is  
 . The rejection region for
. The rejection region for  is given by RR = {z| z < -1.96 or z > 1.96} where the area below -1.96 and under the standard normal density is 0.025; and the area above 1.96 and under the standard normal density is 0.025 as well. Because the observed value 1.4583 does not fall inside the rejection region RR, we fail to reject the null hypothesis.

C and D are not trinomials. (They have 4 terms, not 3.) A is 5th degree, not 4th.
        
             
        
        
        
1 yd is equivalent to 3 ft, so 7 times 3 is 21. 21 is greater than 20, so your answer is 7 yd.
