<span>Here, we first calculate the value of 't' and then go on calculating the probability that the t-value is more than calculated t-value, given the degree of freedom (d.f. = n-1).
t.calc = (77-76)/(5/sqrt(100)) = 1/(1/2) = 2
P(x > 77) = P(t > 2, d.f. =99) = 0.0241= 2.41%</span>
Answer:
6
Step-by-step explanation:
if you notice here Josiah starts with 250 and Katie starts with 215, and in Josiah's equation he saves 25$ each month while Katie save 45$ each month, in order to find our answer we must multiply there starting amount by how many months.
A: 4 months is <em>incorrect</em> because Katie has 45x4+215 is 335, and Josiah has 25x4+250 is 350, so Katie is still behind
B: 5 months is <em>incorrect </em> because Katie has 45x5+215 is 375, and Josiah has, 25x5+250 which is 375, so they have the same amount of savings
C: 6 months is <em>correct</em> because Katie has 45x6+215 is 420, and Josiah has, 25x5+250 which is 400 , so Katie has more savings, Thus C is correct

Answer:
E
Step-by-step explanation:
4 quarts are in a single gallon
Let the amount of potting soil bought last week be
We know that this week's amount is 32 lb
We also know that this week's amount is double the amount of last week's plus 6 lb
So we write the equation:
Solving this equation:
⇒ subtracting 6 from both sides
⇒ Dividing both sides by 2
The answer is: 13
