Answer:

36\ feet

Step-by-step explanation:

Assume that the shadow of an object in this problem is proportional to the height of the object. One can form the following ratio to describe the objects in this problem,

(height):(shadow)

As per the given problem, a (6) foot person casts a (1.7) foot shadow. Therefore, one can form the following ratio,

6:1.7

It is given that there is a lighthouse that has a shadow of (10.2) feet, one is asked to find its height. Use the parameter (x) to represent the unknown; since the ratios are related, one can form a proportion to solve for(x).

6:1.7=x:10.2

Cross products,

(1.7)(x)=(6)(10.2)

Simplify,

1.7x=61.2

Inverse operations,

1.7x=61.2

/1.7

x=36

: diameter of Circle P.<br><br><br><br> 1 = m 3 = 20°, then m =
posledela

The required value of Arc BC m = 140° Option B is correct.

Given that,
AD is the diameter of the circle,
∠1 = ∠3 = 20°
Arc BC is to be determined.


<h3>What is an arc?</h3>

Arc is the measure of angle on the circumference of circle.

Here,
∠1 = arc AB
∠3 = arc CD
Now, for circle p
Since angle 1 and angle 2 are equal to the composition of the arc,
Arc  AD = Arc AB + Arc BC + Arc CD = 180
20 + Arc BC + 20 = 180
Arc BC = 180 - 40

Arc BC = 140°

Thus, the required value of Arc BC m = 140° Option B is correct.

Consider the following hypothesis test H0 p 20 Ha p 20 A sample of 400 provided a sample proportion p 175 a Compute the value of
Bogdan [553]

Answer:

a) -1.25

b) 0.2112

c) -1.96

Step-by-step explanation:

Data provided in the question:

Sample size, n = 400

H0 : p = 20

\bar{p} = 175

Now,

a) The test statistic is  given as:

Z = \frac{(\bar{p}-p)}{\sqrt{\frac{p(1-p)}{n}}}

on substituting the respective values, we get

Z = \frac{(0.175-0.2)}{\sqrt{\frac{0.2\times0.8}{400}}}

= -1.25

b) The p-value = 2 × P(Z <-1.25)

Now from the standard normal table

P(Z <-1.25) = 10.56% = 0.1056

Thus,

p-value = 2 × 1056 = 0.2112

c) for a = 0.05,

the critical value is Z_{\frac{a}{2}}=Z_{\frac{0.05}{2}} i.e Z_{0.025}

Now from standard normal table

Z_{0.025} = -1.96
