Answer:
Right tailed test
Step-by-step explanation:
The null hypothesis is:
The alternative hypothesis is:
This is a right-tailed test since the alternative hypothesis is greater than 30
Suppose the level of significance is 0.05 and we are given a p-value less than 0.05.
Then, we reject the null hypothesis.
5x ÷ x² - 9 + 7 ÷ x + 3
Write the division as a fraction:
- 9 + + 3
Simplify the expression:
- 9 + + 3
Calculate the sum:
- 6 +
Write all numerators above the common denominator:
Add the numbers and you get the final answer:
Answer:
<u>The correct answer is B. 145 in²</u>
Step-by-step explanation:
Let's recall that formula of the surface area of a pyramid:
S.A. = 1/2*(4 * side of the base * height) + side of the base ²
Replacing with the values provided, we have:
S.A. = 1/2*(4 * 5 * 12) + 5²
S.A. = 1/2 * 240 + 25
<u>S.A. = 145 in²</u>
Standard form : Ax + By = C
y = 2x + 5....subtract 2x from both sides
-2x + y = 5...multiply by -1 to make x positive
2x - y = -5 <=== standard form
