Okay. First thngs first, let's divide each of them. 2.6/1.3 is 2. Now in terms of exponents, we would just simply subtract the powers, because we are doing division. 9 - 2 is 7. The value of the expression is 2 * 10^7. Even writing the problem out in number form (2,600,000,000/130), you can still see the answer to the problem as 20 million. The answer is B.
Answer:
"0.0373" seems to be the appropriate solution.
Step-by-step explanation:
The given values are:
n₁ = 43
n₂ = 35
![\bar{x_1}=217800](https://tex.z-dn.net/?f=%5Cbar%7Bx_1%7D%3D217800)
![\bar{x_2}=204700](https://tex.z-dn.net/?f=%5Cbar%7Bx_2%7D%3D204700)
![\sigma_1=30300](https://tex.z-dn.net/?f=%5Csigma_1%3D30300)
![\sigma_2=33800](https://tex.z-dn.net/?f=%5Csigma_2%3D33800)
Now,
The test statistic will be:
⇒ ![Z=\frac{\bar{x_1}-\bar{x_2}}\sqrt{\frac{\sigma_1^2}{n_1} +\frac{\sigma_2^2}{n_2} }](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7B%5Cbar%7Bx_1%7D-%5Cbar%7Bx_2%7D%7D%5Csqrt%7B%5Cfrac%7B%5Csigma_1%5E2%7D%7Bn_1%7D%20%2B%5Cfrac%7B%5Csigma_2%5E2%7D%7Bn_2%7D%20%7D)
On substituting the given values in the above formula, we get
⇒ ![=\frac{217800-204400}{\sqrt{\frac{(30300)^2}{43} +\frac{(33800)^2}{35} } }](https://tex.z-dn.net/?f=%3D%5Cfrac%7B217800-204400%7D%7B%5Csqrt%7B%5Cfrac%7B%2830300%29%5E2%7D%7B43%7D%20%2B%5Cfrac%7B%2833800%29%5E2%7D%7B35%7D%20%7D%20%7D)
⇒ ![=\frac{217800-204400}{\sqrt{\frac{918090000}{43} +\frac{1142440000}{35} } }](https://tex.z-dn.net/?f=%3D%5Cfrac%7B217800-204400%7D%7B%5Csqrt%7B%5Cfrac%7B918090000%7D%7B43%7D%20%2B%5Cfrac%7B1142440000%7D%7B35%7D%20%7D%20%7D)
⇒ ![=\frac{13400}{7347.93}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B13400%7D%7B7347.93%7D)
⇒ ![=1.7828](https://tex.z-dn.net/?f=%3D1.7828)
then,
P-value will be:
= ![P(Z>1.7828)](https://tex.z-dn.net/?f=P%28Z%3E1.7828%29)
= ![0.0373](https://tex.z-dn.net/?f=0.0373)
Answer:
The original function is f(m) = 5(1.07)^m, with the m as an exponent
part A) if the final length is 9.19, we can set f(m) = 9.19 and solve for m
plugging it into a calculator, I get m = ~8.99, so a bit less than 9. therefore, a reasonable domain might be all the m values 9 or below, or m ≤ 9
part B) the y-intercept of a function is the value of the independent variable when the dependent variable = 0. the two variables in your problem are height and number of months - which one do you think is the independent one, and which one is dependent? then re-interpret "value of the independent variable when the dependent variable = 0" in terms of the actual quantities that the variables represent
part C) average rate of change from m = 1 to m = 9
f(9)−f(1)9−1
evaluate, and think about what that represents in terms of height and number of months
