Answer:
The 98% confidence interval for the proportion of successful launches for the new rocket launching system is (0.553, 0.797).
Step-by-step explanation:
We have to calculate a 98% confidence interval for the proportion.
The sample proportion is p=0.675.
![p=X/n=54/80=0.675](https://tex.z-dn.net/?f=p%3DX%2Fn%3D54%2F80%3D0.675)
The standard error of the proportion is:
The critical z-value for a 98% confidence interval is z=2.326.
The margin of error (MOE) can be calculated as:
![MOE=z\cdot \sigma_p=2.326 \cdot 0.052=0.122](https://tex.z-dn.net/?f=MOE%3Dz%5Ccdot%20%5Csigma_p%3D2.326%20%5Ccdot%200.052%3D0.122)
Then, the lower and upper bounds of the confidence interval are:
![LL=p-z \cdot \sigma_p = 0.675-0.122=0.553\\\\UL=p+z \cdot \sigma_p = 0.675+0.122=0.797](https://tex.z-dn.net/?f=LL%3Dp-z%20%5Ccdot%20%5Csigma_p%20%3D%200.675-0.122%3D0.553%5C%5C%5C%5CUL%3Dp%2Bz%20%5Ccdot%20%5Csigma_p%20%3D%200.675%2B0.122%3D0.797)
The 98% confidence interval for the population proportion is (0.553, 0.797).

Answer:
All you do is replace the variable with the numbers given to replace them.
So your new equation is 10-4(2) this was given to you C=10 , D=2
Okay, let's solve it 10-4(2)
4*2 equals 8 so now it's 10-8
10-8

Answer:
D
Step-by-step explanation:
y = 3x - 2 intercepts the y axis at -2
y = -2x + 3 intercepts the y axis at 3
the lines which satisfy these conditions intersect at point D
