What is the tangent ratio for ∠E

Mathematics

Answer:  The tangent ratio for angle E is \dfrac{3}{4}.

Step-by-step explanation:  We are given to find the tangent ratio of angle E in the figure.

From the figure, we note that

the triangle DEF is a right-angled triangle, where ∠D = 90° and ∠E is an acute angle.

We know that

tangent ratio of an angle is given by the length of the perpendicular divided by the length of the base associated with that particular angle.

Now, for angle E, we have

perpendicular = DF = 6 units

and

base = DE = 8 units.

Therefore, the tangent ratio for angle E will be

\tan \angle E=\dfrac{perpendicular}{base}\\\\\\\Rightarrow \tan \angle E=\dfrac{DF}{DE}\\\\\\\Rightarrow \tan \angle E=\dfrac{6}{8}\\\\\\\Rightarrow \tan \angle E=\dfrac{3}{4}.

Thus, the tangent ratio for angle E is \dfrac{3}{4}.

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.

umka2103 [35]

Answer:

option B

Step-by-step explanation:

Given,

mean result (μ) = 65

standard deviation (σ)= 15

probability that student will score between 50 and 80

= P(50< x

= P(50< x

= P(50< x

 = P(Z < 1) - P(Z < -1)

Using z table,  

= 0.8413 - 0.1587

= 0.6826

the correct answer is option B

In mathematics, sometimes the word 'of' means 'multiply'.

\frac{2}{3} * \frac{3}{4} = \frac{6}{12}

Simplify.

\frac{6}{12} = \frac{1}{2}

So, 1/2 is the answer.
