Mathematics
1 answer:
icang [17]3 years ago
3 0

Answer:

Option B.  AA

Step-by-step explanation:

we know that

Angle-Angle (AA) Similarity Postulate, states that If two angles of one triangle are congruent to two angles of another, then the triangles must be similar

In this problem

<em>In the triangle XYZ</em>

∠X=70°

∠Y=90°

∠Z=90°-70°=20° (remember that angle X and angle Z are complementary)

<em>In the triangle UWV</em>

∠V=20°

∠W=90°

∠U=90°-20°=70° (remember that angle V and angle U are complementary)

therefore

Traingles XYZ and UWV are similar by AA Similarity Postulate

An apple farm claims that the average weight of all their apples is 8oz. A sample of 20 apples were picked that had a mean of 7.
Nimfa-mama [501]

Answer:

The mean apple weight is different from 8oz

Step-by-step explanation:

Claim : An apple farm claims that the average weight of all their apples is 8oz.

H_0:\mu \neq 8\\H_a:\mu = 8

n = 20

Standard deviation =s = 0.95

Since n < 30

So we will use t-test

x = 7.77

t =\frac{x-\mu}{\frac{s}{\sqrt{n}}}

Substitute the values :

t =\frac{7.77-8}{\frac{0.95}{\sqrt{20}}}

t =−1.0827

Since we are not given the significance level

So, we will take 5%

So,α = 0.05

Degree of freedom = df = n-1 = 20-1 = 19

So, using t table

t_{\frac{\alpha}{2} , df}=2.093

Since t critical > t statistic

So, we accept the null hypothesis.

So, The mean apple weight is different from 8oz
