Answer:
0.0445937
Step-by-step explanation:
-Given that the sample statistic has a mean of 406 grams, standard deviation of sq root(225) and the null statistic is 411 grams.
-Assuming normal distribution, the test statistic is calculated as:
-we then find the p-value of the test statistic from the z-tables:
P-value=0.0445937
Answer:
1/8
Step-by-step explanation:
I'm going to try to explain this as easy as possible. What I did was take the original shape and divide it by the new shape. For this question, I solved it by dividing 32(the original base) by 4(the new base) and got 8. So the scale factor of the reduction was 1/8.
Step-by-step explanation:
v=l×b×h
300cm²=4×3x×x
300÷12=x²
x=5
3x=3×5=15
a=15×5
