One radius of a circle is the same length as any other radius of the same
circle.
A. True
B. False

Answers

A. True

In a circle, all radii have the same length. The radius is the distance from the center of the circle to any point on its circumference. Since the center is equidistant from all points on the circumference, all radii will have the same length. Therefore, the statement is true.

Gordon types 2,508 words in 38 minutes. Find the unit rate. Gordon types words per minute.​

Answers

Answer:

66 words per minute

Step-by-step explanation:

In 38 minutes , words that can be typed by Gordon = 2508 words

In 1 minute, words that can be typed by Gordon = 2508/38

                                                                                = 66 words

Therefore Gordon types 66 words per minute.

hope it helps :)

Answer:

66

Step-by-step explanation:

To find the unit rate you would need to find how many words Gordon can type in one minute. To do that, all you need to do is divide 2,508 by 38 (which would get you 66 words). If you set up a proportion to solve this it would look somewhat like 2,508/28 = 66/1.

A researcher wishes to test whether the mean of a normally distributed population is greater than 1.06 at the 5% significance level. Based upon 22 independent observations, she observes a sample mean of 1.77 and a sample standard deviation of 0.84. Determine the critical value of the test rounded to the nearest hundredth. (Rounding counts!).

Answers

Answer:

t- critical value =1.721

Step-by-step explanation:

Given

Sample size =n=22

Degree of freedom = sample size -1 = 22-1 =21

The significance level is 5%. This indicates that the test is right tailed.

The alpha value = 0.05

For given right tailed test, with value of alpha = 0.05 and degree of freedom = 21, the  t- critical value =1.721

Solve for x in this equation: 3/4+ |5-x| = 13/4

Answers

Answer:

  x = 2.5 or 7.5

Step-by-step explanation:

Subtract 3/4.

  |5 -x| = 10/4 = 2.5

This resolves to two equations:

5 -x = 2.5   ⇒   x = 5 -2.5 = 2.55 -x = -2.5   ⇒   x = 5 +2.5 = 7.5

The solutions are x = 2.5 or 7.5.

Answer:

b ,a ,c

Step-by-step explanation:

The side opposite the smallest angle is the shortest

The smallest

x = 180 - 70 -62 = 48

48 is the smallest angle so b is the smallest side

The side opposite the largest angle is the longest side

70 is the largest angle so c is the longest side

Help plzzzzz hurry

Answers

Answer:

-9, -5, -4.1, -4

[tex]\\q\leq -4[/tex]

Step-by-step explanation:

I think what you're missing here is that there is a negative sign in front of the q. This means that whatever number you put in for q will be multiplied by negative 1. Positive numbers will become negative, and negative numbers will become positive.

If you substitute 9 for q you will get [tex]-9\geq 4[/tex], which is clearly not true, because -9 is way less than 4.

For writing the equation you divide both sides by -1. When you do this however, you must flip the inequality sign

[tex]-q\geq 4\\q\leq -4[/tex]

the > sign turned into <, and the q and 4 switched signs.

The variable y is directly proportional to the variable x. If y = 12 when x = 14, what is the value of x when y = 747

Answers

Answer:

871.5

Step-by-step explanation:

directly proportional

y = kx

y = 12 when x = 14

12 = k(14)

k = 12/14

k = 6/7

--------------------------

what is the value of x when y = 747

747 = (6/7) * x

Multiply both sides by 7/6

747 * 7/6 = x
