Which statement represents the biconditional statement of the conditional statements?

noname [10]

The measures of two angles have a sum of 180º if and only if the angles are supplements. This statement is true.

A biconditional statement has 2 parts : a conditional statement that states "If hypothesis, then conclusion" and a converse statement which states " If conclusion, then hypothesis" . When both these parts are true, then it is called a biconditional statement.

Talia tossed a penny many times. She got 30 heads and 70 tails. She said the experimental probability of getting heads was 30 70

-BARSIC- [3]

Answer:

The experimental probability of landing on heads is 0.3

Step-by-step explanation:

We are given the following in the question:

Number of heads = 30

Number of tails = 70

Talia said the probability of getting heads is $\frac{30}{70}$ .

She evaluated the wrong probability.

She did not considered total number of trials in the experiment.

Formula for probability:

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

Probability of heads =

$P(H) = \dfrac{30}{30+70} = \dfrac{30}{100} =0.3$

The experimental probability of landing on heads is 0.3

Answer:

$\frac{3}{2}$

Step-by-step explanation:

$[\frac{2}{5}-\frac{3}{10}+(3-1)]\div 1\frac{2}{5}\\\\=(\frac{4}{10}-\frac{3}{10}+2)\div\frac{5+2}{5}\\\\=(\frac{1}{10}+2)\div \frac{7}{5}\\\\=(\frac{2\cdot10+1}{10})\div \frac{7}{5}\\\\=\frac{21}{10}\div \frac{7}{5}\\\\=\frac{21}{10}\times \frac{5}{7}\\\\=\frac{21\cdot5}{10\cdot7}\\\\=\frac{3}{2}$

Enter the missing value into the box to complete the ratio comparing 500 meters to 3 kilometers.

4vir4ik [10]

3 kilometres = 3,000 metres

so the ratio is 500 : 3000

= 1 : 3000/500

= 1: 6

Ray Of Light [21]

I’m guessing the second one since it shows 32 and not 36
