Answer 1

Answer:

a: Angle EBD

b: Can't really phrase this well, a semicircle that is to the left or right of diameter BD

c: Arc EDC

d: 80 degrees

e: 180

Step-by-step explanation:

An inscribed angle is an angle with all 3 points on the circumference of a circle.

A semicircle is half a circle

A major arc is an arc greater than 180 degrees

The inner angle is 80 degrees

Arc BCD is half a circle so its 360/2=180 degrees

There are six checkout tills at a small supermarket. Two of the tills have comfy seats. What is the probability an employee will get a till with a comfy seat?
Give your answer as a fraction

Please can someone help thank you very much :)

Answers

Answer:

1/3

Step-by-step explanation:

2/6 means that 2 out of the 6 tills have comfy seats. 2/6 simplified is 1/3

Answer:

[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

The total amount of tilts is 6

The amount of tilts with comfortable seats is 2

So there are two tilts with comfortable seats out of six tilts that are in the supermarket

Now write it as fraction:

[tex]\frac{2}{6}[/tex] = [tex]\frac{2*1}{2*3}[/tex] (alternatively 2/6)

Here we get the probability

// divide numerator and denominator by 2

[tex]\frac{2*1}{2*3}[/tex] = [tex]\frac{1}{3}[/tex] (alternatively 1/3)

What is the property of 4x+6=18

Answers

Answer: 4x-6= 18

4x=24

x= 24 & 4

x=6

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

I'm not exactly sure of what you mean by property but I think it might be associative property of multiplication?  

But to solve for x you would subtract 6 from 18 which gives your 12. Then you divide by 4 to get the x alone and 12/4 is 3.

A credit card company wanted to estimate the proportion of its customers who pay their credit card minimum balance on time. The company sampled 500 records and constructed a confidence interval for the true proportion of customers who pay their credit card minimum balance on time. The resulting 95 percent confidence interval was (0.765, 0.835). Which of the following is a true statement regarding the value of the point estimate and margin of error of the percentage of customers who pay their credit card minimum balance on time?

a. The point estimate is 0.765 and the margin of error is 0.07.
b. The point estimate is 0.765 and the margin of error is 0.835.
c. The point estimate is 0.80 and the margin of error is 0.035.
d. The point estimate is 0.80 and the margin of error is 0.07.
e. The point estimate could be any number within the interval and the margin of error is 0.035.

Answers

Answer: c. The point estimate is 0.80 and the margin of error is 0.035.

Step-by-step explanation:

Given: The 95 percent confidence interval was (0.765, 0.835).

Confidence interval = Point estimate ± Margin of error.

I.e. Point estimate + Margin of error = 0.835       (i)

Point estimate - Margin of error = 0.765         (ii)

Add (i) and (ii), we get

2 (Point estimate)= 1.60

⇒ Point estimate = 0.80

Put this in (i), we get

0.80+Margin of error = 0.835

⇒ Margin of error = 0.835 -0.80

⇒ Margin of error = 0.035

Hence, the correct statement is:

c. The point estimate is 0.80 and the margin of error is 0.035.

(Show your theoretical yield calculation.)Background for experiement if needed:-Phenylmagnesium bromide will be prepared by the reaction of Mg with bromobenzene in diethyl ether.
