Answer:

B. 1/8 chance

Step-by-step explanation:

Every time you flip a coin you have a 1/2 probability of landing on heads.

If you repeated the process three times in the row

It would be 1/2 x 1/2 x 1/2 = 1/8

The odds they all land on heads is 1/8

what is the slope and equation of a line that is perpendicular to the y-axis passing through (-5,-3)?​
Illusion [34]

Answer:

Slope is m=0

y=-3

Step-by-step explanation:

The slope of any line that is perpendicular to the y-axis is zero.

The reason is that any line that is perpendicular to the y-axis is also parallel to the x-axis and the slope of the x-axis is zero.

The equation of any line perpendicular to the y-axis is and passes through (a,b) is y=b.

The given point is (-5,-3) hence the required equation is

y=-3

PLEASE HELp tHHIS IS dUE IN AN HOUR!!!!! ITS MY LAST QuESTION Tony and Tiffany colleg\ct semi-precious stones. At the Rockhound
DIA [1.3K]

Answer:

Tiffany purchase the better buy.

Step-by-step explanation:

given data

Tiffany paid  = $38

snowflake obsidian = 9 pounds

Tony paid = $19

same type of stone = 3 pounds

solution

Tiffany shopped well in this scenario. Mainly because Tiffany paid less per pound than Tony. This can be calculated by dividing the total amount paid by the amount received by each

so for Tiffany

= $38 ÷ 9

= $4.22 per pound

and for Tony  

=$19 ÷ 3

= $6.33 per pound

so that here Tiffany paid $4.22 per pound and Tony paid $6.33 per pound

so here whole $2.11 more than Tiffany

so that with this Tiffany purchase the better buy.
