Answer:
Anna:2(8)-4
tony=8
anna=2(8)-4
twice of tony's age is 2(8), and it also said 4 years less than.
<span>The mean of the sampling distribution of the mean is the mean of the population from which the scores were sampled. Therefore, if a population has a mean μ then the mean of the sampling distribution μ₁ of the mean is also μ.
So </span>μ = μ1 =82
Now let' calculate σ the standard deviation <span> of the sampling distribution of the mean: It is computed as follows:
</span>σ₁ = σ/√n ==> σ₁ = 6/√n
Answer:
17 cm
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse
8^2 + 15^2 =c^2
64+225 = c^2
289 = c^2
Take the square root of each side
sqrt(289) = sqrt(c^2)
17 = c
