Here we've been given:

  • Area of parallelogram (A) = 690.84 m²

  • Height (H) = 20.2 m

  • Length of base (B) = ?

:\longrightarrow\tt{Area \: of \: parallelogram = Base \times Height} \\  \\ :\longrightarrow\tt{690.84 = B \times 20.2} \\  \\ :\longrightarrow\tt{ \frac{690.84}{20.2} = B} \\  \\ :\longrightarrow\tt{34.2 = B} \\  \\ :\longrightarrow\tt{B = 34.2 \: m}

  • The length of base is <u>3</u><u>4</u><u>.</u><u>2</u><u>m</u><u>.</u>

Answer:

34.2 m

Step-by-step explanation:

We know that

Area of parallelogram = Base × Height

690.84 = B × 20.2

690.84/20.2 = B

34.2 = B

Hence,

Base of parallelogram is 34.2 m

A company has developed a training procedure to improve scores on the SAT. Following the training, 100 high school students take
Pani-rosa [81]

Answer:

The calculated t-test = 1.717 < 1.6604 at 0.05 level of significance

Null hypothesis is accepted at 0.05 level of significance

A company has developed a training procedure is significantly improve scores

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given  sample mean (x⁻ )  = 517

sample standard deviation (s) =90

Mean of the Population (μ) =500

<em>Null Hypothesis :- H₀ :  </em> (μ) =500

Alternative Hypothesis : H₁ :  μ ≠ 500

<u><em>Step(ii)</em></u>:-

Test statistic

                         t = \frac{x^{-} -mean}{\frac{s}{\sqrt{n} } }

                        t = \frac{517 -500}{\frac{90}{\sqrt{100} } }

                        t  =   1.717

<em>Level of significance</em>

                      ∝ = 0.05

                    t₀.₀₅ = 1.6604

The calculated t-test = 1.717 < 1.6604 at 0.05 level of significance

<u><em>Conclusion</em></u>:-

Null hypothesis is accepted at 0.05 level of significance

A company has developed a training procedure is significantly improve scores
