Answer:
f(x) = 3x2 + 5 and y = 3x2 + 5
Step-by-step explanation:
The expressions that follow f(x) = and y = are the same, so these are two different ways to write the same function: f(x) = 3x2 + 5 and y = 3x2 + 5.
Answer:
The observed value of the chi-square statistic is 34.71
Step-by-step explanation:
Given the data in the question';
Calculate the observed value of the chi-square statistic
The chi-square statistic will be;
∑
[ ( O - E)² / E ]
here O is observed frequency of th class
E is expected frequency of th class
= 1, 2 which denote the class of food experts who guess correctly and who didn't guess correctly
so
∈ = n × probability of not guessing correctly = 168 × 2/3 = 112
∈1 = n × probability of guessing correctly 168 × 1/3 = 56
so
∑[ ( O - E)² / E ] = [ ( 92 - 56)² / 56 ] + [ ( 76 - 112)² / 112 ]
= 1296/56 + 1296/112
= 23.14 + 11.57
= 34.71
Therefore, the observed value of the chi-square statistic is 34.71
The speed of the moon is 4.32×10^-6 m/h, to pass it to km/s with the data that they give us, we have to do the following mathematical operation: (4.32×10^-6 m/h)*(1/1000 km/m)*(1/3600 h/s)=1.2x10^-12Km/s. The moon then moves 1.2x10^-12 km every second.NOTE: there is an error in the question, since 1h = 3600s.
