Answer:

1. ∠EDF = 104°

2. arc FG = 201°

3. ∠T = 60°

Step-by-step explanation:

There are a couple of angle relationships that are applicable to these problems.

the angle where chords meet is half the sum of the measures of the intercepted arcs
the angle where secants meet is half the difference of the measures of the intercepted arcs

The first of these applies to the first two problems.

1. ∠EDF = 1/2(arc EF + arc UG)

∠EDF = 1/2(147° +61°) = 1/2(208°)

∠EDF = 104°

__

2. ∠FHG = 1/2(arc FG + arc ES)

128° = 1/2(arc FG +55°) . . . substitute given information

256° = arc FG +55° . . . . . . multiply by 2

201° = arc FG . . . . . . . . . subtract 55°

__

3. For the purpose of this problem, a tangent is a special case of a secant in which both intersection points with the circle are the same point. The relation for secants still applies.

∠T = 1/2(arc FS -arc US)

∠T = 1/2(170° -50°) = 1/2(120°)

∠T = 60°

From past experience, the organization knows that about 20% of all potential donors will agree to give something if contacted by

Veronika [31]

Answer:

Total number of donor who will give first $ 100 = 100 people

Step-by-step explanation:

Given that:

Total percentage of people who donate when contact by phone 20%

Percentage of donating people who will give $100 or more = 5% = 0.05

Total number of donor who will give first $ 100 can be calculated as

calculate the percentage of donor who will give first $ 100

$P(X) = 0.05\times 0.20 = 0.01\ percent$

$\mu_x = \frac{1}{0.01}$

so, total number of the donor who will give first $ 100 = 100 people

Lemons tastes sour to some people. This sourness is inherited through the TAS2R38 gene. About 65% of the population has this gen

Minchanka [31]

Answer:

We are given:

$\hat{p}=0.65$

Margin of error $E=0.02$

Confidence level = 0.99

We need to find the sample size to estimate the proportion of people who carry the TAS2R388 gene.

The formula for finding the sample size is:

$n=\hat{p} (1-\hat{p})\left (\frac{z_{\frac{0.01}{2}}}{E} \right )^{2}$

Where:

$z_{\frac{0.01}{2}}=2.576$ is the critical value at 0.01 significance level.

Therefore, the required sample size is:

$n=0.65(1-0.65) \left(\frac{2.576}{0.02} \right)^{2}$

$=0.2275 \times 16589.44$

$=3774.1 \approx 3774$

Therefore, the required sample size is 3774
