→ Base = 15 and 10

→ Height = 12

→ Area of trapezoid

→ Area of Trapezoid = (a + b)/2 × h

= (15 + 10)/2 × 12

= 150 ft²

∴ The area of Trapezoid is 150 ft²

Answer: E is the answer

Step-by-step explanation:

The population sample that does not produce a biased result is when he asks every fifth student arriving at school. The correct option is E.

Surveys can be used to determine how representative each person's opinions and experiences are.

When conducted properly, surveys offer precise data about people's beliefs and actions that can be utilized to inform significant decisions.

A huge population's characteristics can be described through surveys. No other research methodology can offer such a wide range of capabilities.

This guarantees a more accurate sample to collect focused results from which to draw conclusions and make significant judgments.

Survey bias is when a question is worded or presented in a way that encourages individuals to select one response over another.

The same holds true if your queries are challenging for customers to comprehend and honestly answer.

As, when he asks every fifth student arriving at school, it can lead to an unbiased result.

Thus, the correct option is E.

Answer:

m∡5 = 71°

Step-by-step explanation:

m∡8 = m∡6

m∡6 + m∡5 = 180

180 - m∡6 = m∡5

180 - 109 = 71

Answer:

the measurement of angle 5 is 71

Step-by-step explanation:

m∡8 = m∡6

M∡6 + m∡5 = 180

180 - m∡6 = m∡5

180 - 109 = 71

===========================================================

Explanation:

The first thing to do is to swap the positions of the x < 3 and the x > -1

So you'll end up with x > -1 and x < 3

Now focus entirely on x > -1. Swap the left and right sides, and also swap the inequality sign. So we end up with -1 < x

That means the "x > -1 and x < 3" is the same as "-1 < x and x < 3"

From here, we collapse the two inequalities to form the compound inequality -1 < x < 3

We can say "x is between -1 and 3, excluding either endpoint".

Answer:

B) 1/13

Answer:

There are 406 students in the school

Step-by-step explanation:

Let the number of students in the school be x

The total ratio is 11 + 3 = 14

The ratio that buys lunch is represented by 3

So, we have it that;

3/14 * x = 87

3x = (14 * 87)

x = (14 * 87)/3

x = 406

slope = 3/2

Step-by-step explanation:

rise over run, so    -6-0 / 3-7 = -6/-4 =6/4 = 3/2

Answer:

2/4 or 1/2

Step-by-step explanation:

The solution is, 1/16 is the probability that you land on blue on your first spin and on yellow on your second spin.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

There are four (4) colors to choose from.

The number of sample space is equal to 4.

With the condition given in this item, the probability of landing on blue on the first spin is equal to 1/4.

Similarly, the probability of landing on yellow on the second spin is 1/4.

so, we get,

           P = (1/4)(1/4)  

             P = 1/16

Answer: 1/16 is the probability that you land on blue on your first spin and on yellow on your second spin
