What is the area of a trapezoid?

Mathematics

The area of this trapezoid is 375 inches^{2}

The formula to find the area of a trapezoid is: A= \frac{a+b}{2} h

A = Area
a & b = the base lengths
h = height length

Using this, with the given variables, we can plug our formula in and work it out.

A= \frac{10+40}{2}15.................................Simplify 10+40 to 50

A= \frac{50}{2}15.......................................Simplify \frac{50}{2} to 25

A=25*15...................................Multiply 25*15

A = 375..........................................Final answer

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you further! :D

Mr.chen drove 23 miles south from where he started. 3.25×50=162.5 is what you have to do first because it said that he drove north for 3.25 hours and each hour he drives for 50 miles. Then you have to subtract 162.5 from 185.5 so that you get how far he drove from where he started. 185.5 - 162.5= 23. So he drove 23 miles south from where he started. I hope this helps.

Answer:

x = 94°

Step-by-step explanation:

The measure of the chord- chord angle CED is half the sum of the arcs intercepted by the angle and its vertical angle, that is

\frac{1}{2} ( arc CD + arc AB ) = 82°

Multiply both sides by 2 to clear the fraction

CD + AB = 164°, that is

x + 70 = 164 ( subtract 70 from both sides )_

x = 94°

Employees from A and company B receive annual bonuses. What information would you need to test the claim that the difference in
lyudmila [28]

Answer:

1. The required information are

The average annual bonuses, \bar {x}_1 received by employees from company A

The average annual bonuses, \bar {x}_2 received by employees from company B

The standard deviation, σ₁, of the average annual bonuses for employees from company A

The standard deviation, σ₂, of the average annual bonuses for employees from company A

The number of employees in company A, n₁

The number of employees in company B, n₂

2. The null hypothesis is H₀: \bar {x}_1 - \bar {x}_2 ≤ 100

The alternative hypothesis is Hₐ: \bar {x}_1 - \bar {x}_2 > 100

Step-by-step explanation:

1. The required information are

The average annual bonuses, \bar {x}_1 received by employees from company A

The average annual bonuses, \bar {x}_2 received by employees from company B

The standard deviation, σ₁, of the average annual bonuses for employees from company A

The standard deviation, σ₂, of the average annual bonuses for employees from company A

The number of employees in company A, n₁

The number of employees in company B, n₂

2. The null hypothesis is H₀: \bar {x}_1 - \bar {x}_2 ≤ 100

The alternative hypothesis is Hₐ: \bar {x}_1 - \bar {x}_2 > 100

The z value for the hypothesis testing of the difference between two means is given as follows;

z=\dfrac{(\bar{x}_{1}-\bar{x}_{2})}{\sqrt{\frac{\sigma_{1}^{2} }{n_{1}}-\frac{\sigma _{2}^{2}}{n_{2}}}}

At 0.5 level of significance, the critical z_\alpha = ± 0

The rejection region is z > z_\alpha and z < -z_\alpha

Therefore, the value of z obtained from the relation above more than or less than 0, we reject the null hypothesis, and we fail to reject the alternative hypothesis.

STALIN [3.7K]

Answer:

The range consists of all real numbers where y ≠ 0

Step-by-step explanation:

reciprocal parent function is y = 1/x

If y = 0, then 1 would have to be divided by a number to equal 0. This would require x to equal a number that can divide 1 to equal 0. Because this is not possible, y cannot be 0.
