Answer:
2/3 or 0.66 repeated
Step-by-step explanation:
Since 2022 is only divisible by 1,2,4, and 5, the probability of getting a number that is a divisor of 2020 is 4/6, simplified to 2/3 or %0.66.
Answer:
∠°
Step-by-step explanation:
We know that ∠ is ≅ ∠.
This means that ∠ °
Therefore, °
We know that a trapezoid is °.
To find ∠ ,which is congruent to ∠, we will have to subtract ° from °.
°.
Because ∠≅∠, we will have to divide by to see their measurement.
So,
.
Hence, ∠°.

Answer:
Correct option: (c). Two sided t-test.
Step-by-step explanation:
A test is to be performed to determine whether the people with 16 years of education and 12 years of education have wages that are significantly different on average.
A sample is provided for the wages of people in both the category.
Compute the sample mean and sample standard deviations for both the sample using the formulas:
The hypothesis is:
<em>H₀</em>: The wages of the two groups is not different, i.e. <em>μ</em>₁ = <em>μ</em>₂.
<em>Hₐ</em>: The wages of the two groups is not different, i.e. <em>μ</em>₁ ≠ <em>μ</em>₂.
A test for the difference between two means is to be performed.
Since there is no information about the population standard deviations, use a <em>t</em>-test for the difference between two means.
Thus, the correct option is (c). Two sided t-test.
