Take x-2=0
x=2
put the value of x in the equation
2^2 + 3(2) + k =0
4+6+k=0
10+k=0
k= -10
hope you understand
110.059 rounded to the tenths is 10
The answer:
x = 1
Explanation:
If the line is parallel to the y-axis it has no slope, so you would only write down the x-intercept.
Answer:
Our decision rule will be to reject The null hypothesis H0 if the test statistic is less than -1.645, or if it is greater than +1.645.
Step-by-step explanation:
The hypotheses would be;
Null hypothesis;H0: μ = 500
Alternative hypothesis;Ha: μ ≠ 500
Since it's two - tailed at 0.1 level of significance, then each tail will contain 5% or 0.05. From the z-table attached, the corresponding critical value of 0.05 is approximately 1.645 standard deviations from the mean.
Thus, our decision rule will be to reject The null hypothesis H0 if the test statistic is less than -1.645, or if it is greater than +1.645.
Answer:
X=104 degrees
Explanation:
Opposite angles are congruent.
Answer:
Y=26 degrees
Explanation:
All interior angles of a triangle have a sum of 180(on a plane).
Y+50+104=180
Y=26 degrees
