Answer:

Step-by-step explanation:

<h3>Question 1</h3>

It is assumed the chords have equal length: PQ = SR

If the vertexes connected with the center, the both chords will form a right triangle, with the hypotenuse being the radius.

<u>Then the radius is found using Pythagorean theorem:</u>

r = $\sqrt{20^2 + 21^2}$ = $\sqrt{841}$ = 29

<h3>Question 2</h3>

<u>Use the intersecting secants theorem: and solve for x:</u>

FS*FT = FP*FQ
4(4 + x) = 5(5 + 3)
16 + 4x = 40
4x = 24
x = 6

Answer:

9/8

Step-by-step explanation:

The equation of a proportional relationship is ...

y = kx

The constant of proportionality, k, can be found from ...

k = y/x . . . . . above equation divided by x

Using the given points, we find the constant of proportionality to be ...

k = (3/4)/(2/3) = (3/4)(3/2) = 9/8

The constant of proportionality is 9/8.

Answer:

Option B) $\frac{1}{6}$ Inches

Step-by-step explanation:

Maria's Centipede = $1\frac{1}{12}$ inches = $\frac{13}{12}$ inches

Jerome Centipede = $\frac{11}{12}$

<u><em>To see how much longer Maria's centipede was than Jerome's, we'll subtract the two:</em></u>

=> $\frac{13}{12} -\frac{11}{12}$

=> $\frac{13-11}{12}$

=> $\frac{2}{12}$ inches

=> $\frac{1}{6}$ Inches

Kruka [31]

Answer:

0.6848

Step-by-step explanation:

Mean of \hat{p} = 0.453

Answer = 0.453

Standard deviation of \hat{p} :

= \sqrt{\frac{\hat{p}(1-\hat{p})}{n}} = \sqrt{\frac{0.453(1-0.453)}{100}} = 0.0498

Answer = 0.0498

P(0.0453 - 0.05 < p < 0.0453 + 0.05)

On standardising,

= P(\frac{0.0453-0.05-0.0453}{0.0498} <Z<\frac{0.0453+0.05-0.0453}{0.0498})

= P(-1.0044 < Z < 1.0044) = 0.6848

Answer = 0.6848
