the answer is cubic trinomial
Answer:
4.2 inches
Step-by-step explanation:
Area of rectangle = base × height
base b, = 15 inches
height h, = unknown
area = 63 inches²
63 = 15 × h
h = 63/15
= 4.2 inches
5-(-4)
5 + 4 = 9
exceeds by 9
Answer:
26
Step-by-step explanation:
last year you were 25=5x5 , next year you will be 27=3x3x3 ), you will have to wait till you are 38 more years until you are 64(8^2 and 4^3)
Answer: 0.345
Step-by-step explanation:
Given: The the setup for this hypothesis test:
![H_0:p=0.65\\\\H_a:p](https://tex.z-dn.net/?f=H_0%3Ap%3D0.65%5C%5C%5C%5CH_a%3Ap%3C0.65)
Since , the alternative hypothesis is left tail , so the test is left tail test.
![P_0=0.65\\\\Q_0=1-0.65=0.35\\\\p=\dfrac{126}{200}=0.63](https://tex.z-dn.net/?f=P_0%3D0.65%5C%5C%5C%5CQ_0%3D1-0.65%3D0.35%5C%5C%5C%5Cp%3D%5Cdfrac%7B126%7D%7B200%7D%3D0.63)
The test static for population proportion is given by :-
![z=\dfrac{p-P_0}{\sqrt{\dfrac{P_0Q_0}{n}}}\\\\\Rightarrow\ z=\dfrac{0.63-0.65}{\sqrt{\dfrac{0.65-0.35}{126}}}=−0.409878030638\approx-0.4](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7Bp-P_0%7D%7B%5Csqrt%7B%5Cdfrac%7BP_0Q_0%7D%7Bn%7D%7D%7D%5C%5C%5C%5C%5CRightarrow%5C%20z%3D%5Cdfrac%7B0.63-0.65%7D%7B%5Csqrt%7B%5Cdfrac%7B0.65-0.35%7D%7B126%7D%7D%7D%3D%E2%88%920.409878030638%5Capprox-0.4)
The p-value of z = ![P(z](https://tex.z-dn.net/?f=P%28z%3C-0.4%29%3D%200.3445783%5Capprox0.345)
