Answer:

Given that an image attached with this prove.

1. AD = AB, CD=CB 1. Given

2. OD = OB 2. By definition, the diagonal connecting vertec angles bisects the other diagonal

3. OA = OA 3. By reflexive property

4. triangle AOB = triangle AOD 4. By SSS congruence

5. angle AOB = angle AOD 5. By CPCTC

6. angle AOB = angle AOD = 90 6. both angles addup to 180

7. AC ⊥ DB 7. definition of right angles

A circle has a radius of 3.5. What is the circumference? Use 3.14 for Pi.

VikaD [51]

Answer:21.98

Step-by-step explanation:

It is because the formula for the circumference of a circle is 2 x 3.14 x r so I do the 2 x 3.14 and I get the 6.28 and then 6.28 x 3.5(radius) is 21.98.

I need help solving this problem.

Galina-37 [17]

Answer:

y = $\frac{1}{4}$ x - $\frac{9}{2}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4x + 38 is in this form with slope m = - 4

The line ST is perpendicular to line RS ( angles in a square are 90° )

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-4}$ = $\frac{1}{4}$

y = $\frac{1}{4}$ x + c ← is the partial equation

To find c substitute (2, - 4) into the partial equation

- 4 = $\frac{1}{2}$ + c ⇒ c = - 4 - $\frac{1}{2}$ = - $\frac{9}{2}$

y = $\frac{1}{4}$ x - $\frac{9}{2}$ ← equation of ST

Choose the definition for the function

scZoUnD [109]

Answer:

In mathematics, a function is a binary relation over two sets that associates to every element of the first set exactly one element of the second set. Typical examples are functions from integers to integers or from the real numbers to real numbers.

At a local restaurant, the amount of time that customers have to wait for their food is normally distributed with a mean of 18 m

Colt1911 [192]

Answer:

99.7% of customers have to wait between 8 minutes to 30 minutes for their food.

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 18 minutes

Standard Deviation, σ = 4 minutes

We are given that the distribution of amount of time is a bell shaped distribution that is a normal distribution.

Empirical Formula:

Almost all the data lies within three standard deviation from the mean for a normally distributed data.
About 68% of data lies within one standard deviation from the mean.
About 95% of data lies within two standard deviations of the mean.
About 99.7% of data lies within three standard deviation of the mean.

Thus, 99.7% of the customers have to wait:

$\mu -3\sigma = 18-3(4) = 6\\\mu +3\sigma = 18+3(4) = 30$

Thus, 99.7% of customers have to wait between 8 minutes to 30 minutes for their food.
