Answer:
<u>Type I error: </u>D. Reject the null hypothesis that the percentage of adults who retire at age 65 is less than or equal to 62 % when it is actually true.
<u>Type II error: </u>A. Fail to reject the null hypothesis that the percentage of adults who retire at age 65 is less than or equal to 62 % when it is actually false.
Step-by-step explanation:
A type I error happens when a true null hypothesis is rejected.
A type II error happens when a false null hypothesis is failed to be rejected.
In this case, where the alternative hypothesis is that "the percentage of adults who retire at age 65 is greater than 62%", the null hypothesis will state that this percentage is not significantly greater than 62%.
A type I error would happen when the conclusion is that the percentage is greater than 62%, when in fact it is not.
A type II error would happen when there is no enough evidence to claim that the percentage is greater than 62%, even when the percentage is in fact greater than 62% (but we still don't have evidence to prove it).
1) what law of exponent is being described in the given ?
y⁴ x y⁷ = y¹¹
<h3>Answer :- Product of Powers ✓ </h3>
- When numbers with the same base are multiplied, the power of the product is equal to the sum of the powers of the numbers.
- If 'a' is a non-zero integer, and 'm' and 'n' are whole numbers then, am × an = am+n.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2) what law of exponent is being described in the given ?
(m⁵n³)² = m²x^²n³x^²
<h3>Answer :- Power of a product ✓ </h3>
- We use the power of a product rule when there are more than one variables being multiplied together and raised to a power.
- The power of a product rule tells us that we can simplify a power of a power by multiplying the exponents and keeping the same base.

Answer:
No roots
Step-by-step explanation:
the discriminant Δ = 12²-4×(-10)×(-9) = -216
since ∆ is negative then the equation -10x^2 + 12x − 9 = 0 has no solution .
Answer:
34
Step-by-step explanation:
Distance - formula
Answer:
Hey there!
The line can be expressed into y intercept form, y=3x+1.
Thus, in y=mx+b form, m is the slope, and we see that 3 is the slope of the line.
Let me know if this helps :)
