The answer is A. You can get that in by plugging in and checking or by substitution. In order to use substitution here, you would plug in 3x + 3 into y in the first equation. You would then distribute the 2 and solve for x, which would give you 0. Then you could plug that into either equation to find that y = 3.

Assume that the significance level is alpha equals 0.01. Use the given information to find the​ P-value and the critical​ value(
Aleksandr-060686 [28]

Answer:  0.1010052

Step-by-step explanation:

Given : Significance level : \alpha=0.01

Alternative hypothesis : H_1:\ p\neq\dfrac{3}{4}

The test statistic value : z=-1.64

Since , the alternative hypothesis is two-tailed, so the test is a two-tailed test.

Using standard normal distribution table for z, we have

The P-value of two-tailed test will be :-

2P(z>|-1.64|)=2P(z>1.64)\\\\=2(1-P(z\leq1.64))\\\\=2(1-0.9494974)\\\\=0.1010052

Hence, the P-value = 0.1010052

Given the picture below, find x and both angles.
sashaice [31]

3x+2+x+8=180; 4x+10=180; 4x=170; x= 170/4= 42.5

Angle on top is x+8=42.5+8=50.8

Angle on the bottom is 3x+2=3•42.5+2= 129.5
