For the triangles ABC and MNP m∠A = m∠M, AB = 16, AC = 10, MN = 7, MP = 24. Find the ratio of the A△MNP and A△ABC .

Digiron [165]

Answer:

Ratio of area of triangles MNP and ABC is 1.05

Step-by-step explanation:

There are 2 triangles ABC and MNP.

We are given that ,m∠A = m∠M.

AB = 16 and AC = 10.

MN = 7 and MP = 24.

Area of a triangle ∝ Product of any two sides.

So area of triangle ABC ∝ 16 $\times 10$

Area of triangle ABC = 160 $\times k$ ,

where k is a constant.

So area of triangle MNP ∝ 7 $\times 24$

Area of triangle MNP = 168 $\times k$

So ratio of area of triangles = $\frac{Area of MNP}{Area of ABC}$

= $\frac{168}{160}$

= 1.05

The women athletes in the BIG10 Schools have a long-term graduation rate of 73%. Over the past several years, a random sample of

ivolga24 [154]

Answer:

This means that population proportion of women athletes who graduate from the BIG10 is now not more than 73%

Step-by-step explanation:

Here,

The null hypothesis is p = 0.73

Alternate hypothesis is p> 0.73

The level of significance = 0.10 or 10%

Sample size = 23

Sample proportion = 19/23 = 0.826

Z test statistics

= (p’-p)/Sqrt ((p(1-p)/n))

Substituting the given values, we get –

Z = (0.826-0.73)/Sqrt ((0.73(1-0.73)/23)) = 1.037

Thus, the P values for Z>1.037

= 1- P(Z less than or equal to 1.037)

= 1- 0.8501

= 0.150

P-value is greater than the level of significance

We will accept the null hypothesis

This means that population proportion of women athletes who graduate from the BIG10 is now not more than 73%
