Answer:
x = -3
Step-by-step explanation:
Notice that the addition of angle <CDH plus angle <HDE have to give the measure of angle <CDE (which is 144 degrees as stated in the problem)
Then, we can say in equation form:
<CDH + <HDE = 144
replacing with their expressions in terms of x:
x + 93 + 57 + x = 144
solving for x:
2 x + 150 = 144
2 x = 144 - 150
2 x = - 6
x = -3
Answer: We reject the null hypothesis.
Step-by-step explanation:
Since we have given that
n = 223
Number of subjects developed nausea = 50
We need to claim that more than 20% of users develop nausea.
So, Hypothesis:
test statistics would be
At 0.10 level of significance, z = 1.28
Since 0.373<1.28 so, test statistic is less than critical value.
Hence, we reject the null hypothesis.
Answer:
156
Step-by-step explanation:
8-4= 4+9 = 13 x 12= 156
Hope this helped
Answer:
When comes to initial value, x is equals to 0.
So x = 0 is substitute into the function.
In Indices Law, any values to the power of 0 will be 1.
So the initial value of function will be :
