Find the radius and the diameter to the nearest hundredth when C = 7π yd. Use 3.14 for π.

Mathematics

Answer:

Diameter = 7

Radius = 3.5

Step-by-step explanation:

Hi! Ace here.

So, the formula to find circumference is dπ or 2rπ

So to find the diameter, you do the circumference/π

To find the radius, you'd do the circumference/2π

Plug-in those numbers and there you go!

Hope this helps, let me know if you have any questions.

I know this was a very vague explanation so I encourage you to ask any questions. Thank you!

Answer:

B: 280

Step-by-step explanation:

The regression line predicts that when x equals 5:

log_{10}(y) = 2.447

In order to find the value for y, one must simply apply the following logarithmic property:

if : log_{b}(a) = c

then: b^c = a

Applying it to this particular problem:

log_{10}(y) = 2.2447\\10^{2.447}= y\\y=280

Therefore, the regression line predicts y will equal 280 when x equals 5.

A certain high school class consists of juniors and seniors. There are
Genrish500 [490]

Answer:

10 SENIORS

Step-by-step explanation:

x=# of seniors

y=# of juniors

x+y=23, x=2y-7

  1. plug the value of x in the second equation into the first
  2. (2y-7)+y=23
  3. Remove parentheses
  4. 2y-7+y=23
  5. Combine like terms
  6. 3y-7=23
  7. Add 7 to BOTH sides
  8. 3y=30
  9. divide BOTH sides by 3
  10. 3y/3=30/3
  11. y=10
  12. There are 10 juniors in the class
  1. FINAL STEPS
  2. Plug y (which is 10) into the first equation
  3. x+y=23
  4. x+10=23
  5. subtract 10 from BOTH sides
  6. x=13
  7. Since X equals the number of seniors, there are 10 seniors in the class

What is the slope of a line perpendicular to Line AB given A (6,2) and B (-3,2)
GarryVolchara [31]

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m of AB using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = A(6, 2) and (x₂, y₂ ) = B(- 3, 2)

m = \frac{2-2}{-3-6} = \frac{0}{-9} = 0

A line with a slope of zero is a horizontal line, parallel to the x- axis.

Thus a line perpendicular to AB is a vertical line parallel to the y- axis.

The slope of a vertical line is undefined

What is the probability of a player having their game terminated?
Oduvanchick [21]

Answer:

0.14

Step-by-step explanation:

When the game starts, either thee will be a hit or a miss.

The probability of hit = 0.3

Probability of miss = 0.7

Further, after a hit, the probability of hit = 0.3

And the probability of miss= 0.7

Continuing in this way, if we get 2 continuous miss, the game will terminate.

Hence,

the probability of game to terminate = Probability of first miss + Probability of second miss

                                                               = 0.7 +0.7

                                                               = 0.14
