The numbers 7,11,12,13,14,18,21,23,27,and 29 or written on supercars in the cards are placed on the table with the number space and down the probability of picking a car with an even number is

3/10

Step-by-step explanation:

There are 10 cards, 3 of which are even.

So, it would be a 3 out of 10 chance of picking an even card as 3 and 10 cannot be divided by the same number.

If you needed a percentage answer it would be 30%

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
