Answer:
x= 6
Step-by-step explanation:
We can use the Pythagorean theorem to find x
x^2 + 2.5^2 = 6.5 ^2
x^2+ 6.25 =42.25
Subtract 6.25 from each side
x^2+ 6.25-6.25 =42.25-6.25
x^2 =36
Take the square root of each side
x = sqrt(36)
x= 6
Answer: x = 24.5
Step-by-step explanation: Sample mean is the average value of a fraction of the whole population. It is also an estimated of how or what the whole population is doing. To determine it, there is the following formula:
x = ∑
, where:
x is sample mean;
is each of the values;
N is the quantity the sample has;
From the given data, N = 16, so,
x = 
x = 24.5
The sample mean is x = 24.5
Answer:
t must be greater than 5.0
Step-by-step explanation:
P ( t ) = 1050e^0.16t
We want P(t) > 2337
2337 < 1050e^0.16t
Divide each side by 1050
2337/1050< 1050/1050 e^0.16t
Take the natural log of each side
ln (2337/1050)) < ln(e^0.16t )
ln (2337/1050) < 0.16t
Divide by .16
ln (2337/1050)/.16 < 0.16/.16t
ln (2337/1050)/.16 < t
5.00049<t
Answer:
π2,√80,12
Step-by-step explanation:
π2= 6.28
√80= about 8
12=12

B. Up
Because a positive ‘a’ value will make the parabola open upwards, and because the power is 2 (even) both sides will open up in a ‘U’ shape
